The ovary is the female reproductive organ, consisting of oocytes and somatic cells (granulosa cells, theca cells, endothelial cells, supporting connective tissue) []. The granulosa cells play an important role in the fate of follicular development or atresia in poultry. Apoptosis was also induced upon p66SHC overexpression (Figure 4K), as shown by decreased Bcl2 and increased Bax and cleaved caspase 3 (Figure 4L). Primary ovarian insufficiency (POI) or premature ovarian failure (POF) is a common cause of female infertility [2,3,4]. KGN, a human granulosa-like tumor cell line, was a gift from Prof. The granulosa cells will also secrete _____ which inhibits FSH release from the anterior pituitary, •Ovaries contain follicles which will develop into ova 2. 1): (1) follicular growth through primordial, primary, and secondary stages (gonadotropin-independent phase), (2. PTEN (encoding phosphatase and tensin homolog) is a well-known tumor suppressor gene that functions as a mediator of apoptosis and is crucial for mammal reproduction. The human granulosa cells were identified by detection of the marker FSHR using immunocytochemistry and the proportion of cells staining positive for FSHR is >. In addition, activin, either alone or with FSH, has an autocrine action on granulosa cell differentiation and oocyte maturation, leading overall to promotion and maintenance of folliculogenesis [1-3]. The functions of GCs include the production of a myriad of growth factors that are vital for oocyte development, and of sex steroids, which regulate ovarian function. ANGPTL4 inhibits granulosa cell proliferation in polycystic ovary syndrome by EGFR/JAK1/STAT3-mediated induction of p21. The formation of the antral follicle stage is defined by the establishment of a fluid-filled cavity in the follicle, known as the antrum, and the differentiation of the granulosa cells into two populations, mural granulosa cells and cumulus granulosa cells (Figure 1F). Learn about the diagnosis,. The cells building the follicle, a primary functional unit of the ovary, such as granulosa cells (GCs), were demonstrated to possess certain stem-like properties. Granulosa cells are a type of cell in your ovaries that produce estrogen and progesterone. The corona radiata is the innermost layer of the cells of the cumulus oophorus and is directly adjacent to the zona pellucida, the inner protective glycoprotein layer of the ovum. Human ovarian granulosa cell lines KGN (Procell CL-0603) were kindly provided by Procell Life Science & Technology Co. Heavy, irregular menstrual bleeding and. Granulosa cell tumors (GCTs) are rare ovarian tumors that produce high estrogen and can cause irregular periods, bleeding or early puberty. We identified a unique A-kinase anchoring protein (AKAP13) containing a Rho guanine. 001; Fig. Exogenous hormone administration. In the ovary, the corpus luteum (CL) forms a temporal structure. To achieve these functions, GCs are the most active cell lineage in the ovaries in terms of. And then, all animals were sacrificed, ovaries and blood were collected for testing. The adult-subtype representing 95% of all GCTs, develop in perimenopausal or postmenopausal women, at a peak age. Consequently, estrogen levels begin to rise. Oocytes mature in follicles surrounded by nurturing granulosa cells and all are enclosed by a basal lamina. Taken together with our findings, this emphasizes the need for. This phenotype is also observed when. They are distinct from other ovarian carcinomas in their hormonal activity; their ability to secrete estrogen, inhibin, and Müllerian inhibiting substance. These studies suggest the impor-tance of granulosa-theca interaction in the mechanism of regulating ovarian follicular development. Background The major function of the ovary is to produce oocytes for fertilisation. We propose that the proximal promoter region can be. The human granulosa cell line (KGN) was provided by Professor Qiao Jie, Department of Obstetrics and Gynecology, Peking University Third Hospital. 25 (OH) D3 promotes ovarian granulosa cell proliferation by promoting the ability of cells to divide, and may accelerate cell cycle progression by up-regulating THBD and down-regulating CDKN2D express. In addition. Thus, it is possible that proliferative signals exerted via ERK1/2-pathway could be not sufficient to counteract the pro-apoptotic stimulus during the early/mid-antral. 001; Fig. 9 The effect of ECM proteins on granulosa cell proliferation is dependent on follicle size, suggesting that the ECM composition within. (Theca is greek for 'box'). They are estrogen secreting tumours and present as large, complex, ovarian masses. It predicts the ovarian response in controlled ovarian hyperstimulation cycles. Granulosa cell. The luteinizing hormone receptor (LHCGR) is expressed at low levels in mural granulosa cells and cumulus cells of antral follicles and is induced dramatically in granulosa cells but not in cumulus cells by follicle-stimulating hormone (FSH). They also give rise to granulosa theca cell tumors (GCT), which form about 5 percent of ovarian neoplasms and are the commonest sex cord-stromal tumors of the ovary (70 percent). Granulosa cells (GCs) are closely associated with oocytes and the production of female sex hormones. On this basis, it is very likely that the oocyte ages as the ovary ages. The granulosa cells are peri-luteal cells; however, the cytoplasm is still relatively compact compared to granulosa cells collected from ovulatory follicles (). We now demonstrate for the first time that GDF8 is expressed in human granulosa cells and follicular fluid. Then, the effects of PA alone or combined with melatonin on viability, apoptosis and endoplasmic reticulum (ER) stress in granulosa cells were detected by methyl thiazolyl tetrazolium (MTT) assay, flow cytometry assay and western. Degenerated granulosa cells and cumulus cells have been shown in relation to mitochondrial swelling, leading to cell apoptosis and follicle atresia. They are distinct from other ovarian carcinomas in their hormonal activity; their ability to secrete estrogen, inhibin, and Müllerian inhibiting substance. In cultured rat granulosa cells, DHT suppressed follicle stimulating hormone (FSH)-induced granulosa cell proliferation and increased the accumulation of cells in the G2/M phase. A juvenile form that develop in children and young women has distinct clinical and pathologic features (hyperestrinism and precocious puberty). The generation of genomically stable and functional oocytes has great potential for preserving fertility and restoring ovarian function. At the antral stage, atresia essentially results from the apoptosis of granulosa cells (GCs) [1,2]. Most granulosa cell tumors (95%) occur after the menopause (adult form) and are unusual before. The granulosa cells will secrete progesterone after ovulation. To delineate the gene expression profiles in pre-granulosa cells during primordial follicle formation, Lgr5-EGFP-single-positive cells were isolated from embryonic day (E) 17. Mutation of FOXL2 in granulosa-cell tumors of the ovary. Iron overload in EMFF induces granulosa cell ferroptosis. Cells were washed with PBS and incubated with fluorescently coupled secondary antibody. Bovine luteal cells produce progesterone (P4), an important steroid hormone, to maintain pregnancy 8. The cells were thoroughly washed with. Objective: To study the biological effects of resveratrol on the growth, electrophysiology, and mitochondrial function of human granulosa cells (h-GCs). Granulosa cell tumors are the most common sex-cord stromal tumors reported in domestic animals and have been reported in horses, cows, and dogs, and laboratory animals such as non-human primates, mice, and rats. Although GCs are sources of pro-angiogenic factors for the developing follicle, these cells make up an avascular layer that surrounds the oocytes in the cortical region of the ovary and are separated from the theca cells (which are. The ovarian follicle, consisting of an oocyte surrounded by granulosa and theca cells, represents the basic functional unit of the ovary. It remains elusive whether functional oocytes can be generated from adult female somatic cells through reprogramming to. Finally, the lymphocyte separation solution was added and centrifuged at 626 ×g for 10 min. To investigate the implication of EGR1 and SOX9 in. In the present study, we focused on characterizing the proteome in granulosa cells in patients with biochemical premature ovarian insufficiency (bPOI) in order to identify differential proteins and investigate the fundamental mechanisms of POI. The function of ovarian granulosa cells is bound up with follicle development and POI process, knockdown of DANCR might influence. Patient(s): This study included h-GCs from seven infertile women undergoing assisted reproductive techniques. Polycystic ovary syndrome. The formation of the antral follicle stage is defined by the establishment of a fluid-filled cavity in the follicle, known as the antrum, and the differentiation of the granulosa cells into two populations, mural granulosa cells and cumulus granulosa cells (Figure 1F). ; discus proligerus can refer to the attachment between cumulus oophrous and membrane granulosa. Presently, there are no reports on the effects of BMP15 on non-luteinized human granulosa cells, which reflect granulosa cells of growing. This work, for the first time, demonstrated the global gene expression pattern in specific follicular compartments using high-throughput technology. Granulosa cell tumors (GCTs) of both adult (AGCT) and juvenile (JGCT) types can rarely be completely or dominantly cystic, creating diagnostic difficulty because the cyst lining epithelium is often denuded. The results of the present study showed that SGPL1 was expressed mainly in granulosa cells, Leydig cells, spermatocytes, and round spermatids. CCs are supporting cells of the oocyte that protect the oocyte from the microenvironment, which helps oocyte growth and maturation in the follicles. 25 (OH) D3 promotes ovarian granulosa cell proliferation by. Granulosa cells (GCs) must respond appropriately to follicle-stimulating hormone (FSH) for proper follicle maturation. 5 per 100 000 women per year 6-8. This is followed by the formation of small, fluid-filled cavities within the follicle that coalesce to form the early antral (or tertiary) follicle ( 8 ). Follow-up information was obtained by. Cell morphology in E 2-treated cells (B). (15,10,6) They are usually unilateral and benign in mares. Zhou et al. Ovarian development requires the combination of germ cells and several types of somatic cells. 8 Adult granulosa cell tumors occur more often in middle-aged and postmenopausal. FSHR is a granulosa cell specific protein expressed and localized in the cytoplasm of granulosa cells (Fig. Among all species investigated, cattle have become an excellent model for in vitro studies on follicular biology, both because of their resemblance with humans in terms of follicular biology and the importance of reproductive failure as a cause of lost. After treatment with FSH, the mRNA level of Wnt2 was increased in cultured granulosa cells (Castanon et al. Granulosa cells seeded onto uncoated tissue culture plastic flatten in a monolayer and spread with little interaction between neighboring cells, 21, 29, 30, 32 - 36 similar to fibroblast cells. Design: Preclinical study. Its main purpose in many animals is to. It secretes hormones that influence stages of the menstrual cycle. Jun 5, 2021 · The cells building the follicle, a primary functional unit of the ovary, such as granulosa cells (GCs), were demonstrated to possess certain stem-like properties. We established an SV40 large T-immortalized primary human granulosa-lutein cell line, which was named SVOG 28. Follicular fluid (FF) exosomal microRNAs (miRNAs) have been proven to regulate the function of GCs. GCTs can be divided into adult (95%) and juvenile (5%) types based on histologic findings. 2 Proliferation and steroid synthesis of GCs are regulated by many factors, including IGF, BDNF, LH, and FSH. It secretes hormones that influence stages of the menstrual cycle. And then, all animals were sacrificed, ovaries and blood were collected for testing. The granulosa lutein cells do have aromatase, and use it to produce estrogens, using the androgens previously synthesized by the theca lutein cells, as the granulosa lutein cells in themselves do not have the 17α-hydroxylase or 17,20 lyase to produce androgens. It has two histopathologic types with different clinical and biologic features: adult GCT and juvenile GCT. They represent a multipotent cell population that has been differentiated to neuronal cells, chondrocytes, and osteoblasts in vitro. As the basic unit of reproduction, ovarian follicles are composed of a central oocyte and the surrounding endocrine cells (the inner layer is composed of granulosa. As the technology development, RNA-seq is a very useful tool to uncover the transcriptomic changes of oocytes and granulosa cell and to discover the interaction of different types of cells and. , 2010). Granulosa cells were plated at 5 × 10 4 and theca cells at 2. GCs surround the oocyte, promote oocyte development, produce sex steroids and growth factors, and overall contribute to normal folliculogenesis and menstrual cycle [ 1]. The specific expression profile and function of circular RNAs (circRNAs) in mammalian ovarian follicles, especially during the atresia process, are unclear. DANCR is associated with POI and knockdown of DANCR induces granulosa cells aging. [Google Scholar] Zhang M, Su YQ, Sugiura K, Xia G, and Eppig JJ. Mutation of FOXL2 in granulosa-cell tumors of the ovary. One of the first ligand-receptor systems to be identified in the. Granulosa cell tumors account for 5-8% of all ovarian tumors. Adult granulosa cell tumors are uncommon ovarian tumors mainly diagnosed after the age of 30, and the average age is roughly 55. Granulosa cells can also have specific names depending upon location within the follicle. Adult granulosa cell tumour of the ovary is a type of ovarian sex cord / stromal tumour. This study investigated the role and underlying mechanism of GH in OS and apoptosis in granulosa cells (GCs) of patients with polycystic ovary syndrome (PCOS). Culture of granulosa cells has for long provided a useful tool to understand the molecular processes underlying ovarian follicle development. She declined further surgery or treatment due to fertility desires. Modelling of complex biological systems was performed using Ingenuity Pathway Analysis (IPA). Granulosa cell tumors are thought to arise from normal proliferating granulosa cells of the late preovulatory follicle and exhibit many morphological and biochemical features of these cells. The first wave of pre-granulosa cells contributes to the formation of the first class of PFs in the medulla area and will be the follicles contributing to the onset of puberty (Zheng et al. The surface area of each granulosa cell was measured by an area measurement system associated with the BZ-9000 microscope. categorized Sertoli-Leydig tumors as a separate group, both in the dog and in cattle. The present study aimed to extend the culture of GCs in vitro. Therefore, OGCs offer a potent. Granulosa cell tumors account for 12% of all sex cord-stromal tumors. Granulosa cell tumors of the ovary cause higher than normal levels of estrogen in a woman's body. The hormonal features of AGCT explain the clinical manifestations and. The ovarian follicle is the basic functional unit of the ovary, comprising theca cells and granulosa cells (GCs). The analyses elucidated a clear tendency of granulosa cells in shifting its expression profile from proliferation to differentiation during follicular development. When granulosa cells overexpressed p66SHC (Figure 4G-H), the inhibition of ROS (Figure 4I) and MDA generation and the promotion of SOD in cells (Figure 4J) by MDL-800 were broken. The functions of GCs include the production of a myriad of growth factors that are vital for oocyte development, and of sex steroids, which regulate ovarian function. What Are Granulosa Cell Tumors? Granulosa cell tumors are tumors that develop from the granulosa cells (a somatic cell of the sex cord). Granulosa cells are ovarian follicular cells that produce oestrogen and progesterone, and have stem-like properties. Sertoli cell tumours can present mildly hard to hard on strain elastography. Oleic acid is an abundant free fatty acid present in livestock that are in a negative energy-balance state, and it may have detrimental effects on female reproduction and fertility. In this study, we compared the in vitro fertilization and embryo transfer (IVF-ET) results of 22 patients with PCOS and 25 patients with tubal factor infertility and detected the ROS levels in the GCs of these two groups. Expression of LHCGR is increased in a significant subpopulation of granulosa cells (GCs) in small antral follicles from PCOS. The granulosa cells simultaneously undergo a series of major changes in form and function (luteinization). Methods: Granulosa cells from immature female mice were cultured for 24 h in medium containing PA and/or melatonin. A thick glycoprotein layer develops between the oocyte and the zona granulosa, called the zona pellucida. The granulosa cell number is a key determinant of the follicular oxygen concentration , and in a mathematical model, the oxygen concentration in follicles was predicted to be low [5, 6]. Granulosa cells, one of somatic cells in follicle, play a key part in the follicle development in PCOS. IGF-I also amplifies the synergism observed between FSH and testosterone in aromatase expression. Granulosa cells secrete inhibin. To further support our findings, the same results were obtained based on mIF, confirming overlap with the. The human granulosa cells were identified by detection of the marker FSHR using immunocytochemistry and the proportion of cells staining positive for FSHR is >. Granulosa cell tumors constitute less than 5 % of all ovarian tumors. ; discus proligerus can refer to the attachment between cumulus oophrous and membrane granulosa. Adult granulosa cell tumor (AGCT) is a rare ovarian cancer representing two to five percent of all ovarian malignancies. 5a), and play important roles in FGC development and in the formation of. A thick glycoprotein layer develops between the oocyte and the zona granulosa, called the zona pellucida. report that the CNOT6/6L subunit of the CCR4-NOT complex is downstream effectors of the pituitary gonadotropin follicle-stimulating hormone (FSH) in ovarian granulosa cells. It is the most common (70%) sex cord stromal tumor and the most common (80%) hormone-producing ovarian tumor 2-5. In culture, human GCs are viable for several days and produce progesterone, yet. Furthermore, GCs express markers specific for MSCs such as CD105, CD90 and CD44 and differentiate into other cell types such as osteoblasts, neurons and chondrocytes [ 9 ]. , 2010). The major functions of granulosa cells include the production of sex steroids, as well as myriad growth factors thought to interact with the oocyte during its development. Dynamic expression of Impdh2 in oocytes, granulosa cells, and preimplantation embryos. PFA is characterized morphologically by oocyte growth to a diameter of >20 μm, and proliferation and transition of the squamous pre-GCs into cuboidal/columnar granulosa cells (GCs). Adult granulosa cell tumors are uncommon ovarian tumors mainly diagnosed after the age of 30, and the average age is roughly 55. Granulosa cells (GCs) are multilayered somatic cells within the follicle that provide physical support and microenvironment for the developing oocyte. Although the role of macroautophagy/autophagy in ovarian function has been reported, its contribution to the regulation of GC characteristics remains elusive. 8 women with PCOS and 8 women without PCOS were included in this study. Only about 30,000 make it to the primordial follicle stage. ; Ocala, FL), suspended in DMEM/F12 supplemented medium as described above. HS induced ROS accumulation and reduced the viability of granulosa cells. It has been confirmed that during the ovarian follicular development process there are. GCT accounts for 2% to 5% of all ovarian cancers and can be divided into two subtypes according to the differences of the age of patients, clinical and histopathologic features. Granulosa cell tumors (GCTs) are a type of ovarian tumor. Then the key gene in granulosa cell was measured by RT-PCR. One representative experiment of. CCs are supporting cells of the oocyte that protect the oocyte from the microenvironment, which h. Granulosa cell abnormalities are characteristics of premature ovarian insufficiency (POI). Several previous research reports have demonstrated the involvement of the AKT and ERK signaling pathways. The postnatal mouse ovary is rich in quiescent and early-growing oocytes, each one surrounded by a layer of somatic granulosa cells (GCs) on a basal lamina. She developed tumor progression and drug-induced nephritis after. Granulosa cells express vimentin , while luteinized GC populations were also reported to express Oct-4 [14,40], further reinforcing suggestions of resemblance to MSC populations. Granulosa cells start to express FSH receptors at the primary follicle stage. This type of tumor is known as a sex cord-stromal tumor and usually occurs in adults. 2019 Dec 24;29 (13):4256-4267. Richards, in Encyclopedia of Reproduction (Second Edition), 2018 Cumulus Cells Are Unique. tween granulosa cell tumor and Sertoli-Leydig cell tu- mor.

In addition to oocyte cells, follicular fluid contains granulosa, thecal and ovarian surface epithelial cells. . Granulosa cells
This study was done using follicular cells collected from bovine ovarian follicles at the early developmental stage. Three-dimensional chromatin architecture is an important transcription regulator; however, little is known about its dynamics and role in transcriptional regulation of granulosa cells during chicken folliculogenesis. The factors needed for GCs to differentiate within each layer are transforming growth factor beta (TGFB) and insulin-like growth factor (IGF), as well as the activation and modification of biochemical pathways involved in folliculogenesis. CCs are supporting cells of the oocyte that protect the oocyte from the microenvironment, which helps oocyte growth and maturation in the follicles. 2013; Schmidt et al. There are about 30 trillion (3 × 10 13) human cells in the adult human body, varying from about 20 to 40 trillion depending on the sex, age and weight, and a roughly equal number of bacterial cells. As ERβ is primarily expressed in the granulosa cells (GCs), we explored the gonadotropin-regulated GC genes that induce maturation of antral follicles. Fluorescence microscopy, colored with DAPI. In recent years, the role of Neuregulin-1 (NRG1), a member of the EGF-like factor family, has received considerable attention due to its neurodevelopmental and cardiac function. Notably, a positive effect on the preservation of ovarian function was evidenced, since the loss of follicles in the POI-like mouse ovaries. Moreover, in vitro experiments indicated that TIMP1 had the ability to promote the cell proliferation and elevate the transcriptional levels of four genes associated with goat prolificacy, including BMPR-1B, BMP15, GDF9, and FSHB, in granulosa cells. Diagnosed and treated early, it's not likely to return. Here we first report that the suppression of auto. The granulosa cells expressing FOXO3 coincided with apoptotic cells, indicating a role of FOXO3 as a proapoptotic factor in granulosa cells of porcine ovaries. categorized Sertoli-Leydig tumors as a separate group, both in the dog and in cattle. The corpus luteum is a transient endocrine organ that predominantly secretes progesterone, and its primary function is to prepare the estrogen primed endometrium for implantation. Granulosa cell tumors are the most frequently diagnosed ovarian tumor in bitches, representing up to 50% of tumor in female dogs, and arise from the granulosa cells in the tertiary follicles. Altered expression of ITGAX, TAB2, and especially CAV1, a dysregulated hub, may contribute to oxidative stress, abnormal lipid metabolism, and. Testicular granulosa cell tumor of the adult type is a very rare tumor, and to date, only a small number of cases have been reported. Sera, follicular fluids and granulosa cells were obtained from individuals undergoing IVF-ET treatment. Pathological changes in GCs are found in several ovarian disorders. A study conducted by.

Among all species investigated, cattle have become an excellent model for in vitro studies on follicular biology, both because of their resemblance with humans in terms of follicular biology and the importance of reproductive failure as a cause of lost. A 37 year old G0 female was initially diagnosed with granulosa cell tumor (GCT) after left ovarian cystectomy for symptomatic pelvic mass in 2005. But despite their separation from oocytes, the somatic cells, now called granulosa cells, maintain contact with oocytes using transzonal processes, or TZPs. Ovarian granulosa cell tumors are a form of sex-cord stromal tumors that account for 1%-2% of all ovarian tumors and can be of the juvenile or adult type []. During follicle formation, granulosa cells (GCs) change their morphology and physiological properties. In contrast, these granulosa cells express other progesterone binding proteins, one of which is referred to as Progesterone Receptor Membrane Component 1 (PGRMC1). With development of gap junctions they connect to each other and to the oocyte []. ; Ocala, FL), suspended in DMEM/F12 supplemented medium as described above. During early embryonic development, at 7. TZPs originate from granulosa cells, and some of them terminate at the oolemma to provide a means of direct connection between oocytes and granulosa cells. Steroidogenesis and cell viability were studied to explore the granulosa cell function on BMPR-IB gene modulation. All data. Here the authors show that granulosa cell mevalonate pathway abnormalities contribute to aneuploidy during ovarian aging and that supplementation. These tumors are considered. Rosales-Torres showed that FSH increased S1P synthesis in granulosa cells by phosphorylating SphK1 15. Pathological changes in GCs are found in several ovarian disorders. 5 μg/ml FSH for 6 h prior to LPS exposure or treated with 2.

The dynamic transcriptional regulation and interactions of human germlines and surrounding somatic cells during folliculogenesis remain unknown. 402C > G; p. Granulosa cells of the ovary are very important components that are involved in the production of sex steroid hormones and a milieu of growth factors involved in interaction with oocyte development. The yolks were removed carefully from the follicles with ophthalmic scissors. Oocyte meiotic defects increase with age and contribute to decreased oocyte quality. Providers often use surgery to treat it. Due to the secretive activity of granulosa cells (GCs), they play a vital role in folliculogenesis. Adult-type granulosa cell tumors (AGCT) account for 1-2% of all ovarian tumors and 95% of granulosa cell tumors. Granulosa cells, one of somatic cells in follicle, play a key part in the follicle development in PCOS. Excess estradiol, when sensed by the hypothalamus and anterior pituitary, decreases the production of gonadotropin-releasing hormone, FSH, and LH. Bovine granulosa cells were isolated from adult bovine ovaries obtained from a local abattoir as described previously [17,18,38]. Interestingly, granulosa cells in the outermost layers of Enzy-FL expressed CYP17A1 by Day 4 of culture while maintaining inhibin α-subunit expression and a cuboidal nucleus. In contrast, medullar BPG cells differentiate along a distinct pathway to become wave 1 granulosa cells. No staining was observed in the theca cells (H). All the experiments were repeated three times, and the representative images are shown. Granulosa cells were identified on cytospin preparations on the basis of their morphology. By FIB imaging, a special ciliary structure was discovered in granulosa cells for the first time. Thus, in primordial, primary and small preantral follicles apoptotic cell death affects oocytes, while in late preantral,. Once isolated, the granulosa cells were divided and were either used for subsequent experiments such as RNA or protein extraction, or cultured for immunofluorescence staining, or stored at −80° C until further analysis. Breast cancer amplified sequence 2 (BCAS2) is necessary for spermatogenesis, oocyte development, and maintaining the genome integrity of early embryos in mice. Although the physiological properties of normal granulosa cells have been studied extensively, little is known about the molecular mechanism of GCT progression. The most common site is the tongue, followed by the mammary gland, upper respiratory tract ( throat and bronchus), and gastrointestinal tract (esophagus, large intestine and perianal area, stomach, small intestine, and bile duct). CircRNA expression profiles were generated from porcine. HS induced ROS accumulation and reduced the viability of granulosa cells.
