Abstract
Sow fertility is an economically important quantitative trait. Hundreds of quantitative trait loci (QTLs) containing tens of thousands of potential candidate genes are excavated. However, among these genes, non-coding RNAs including long non-coding RNAs (lncRNAs) are often overlooked. Here, it is reported that NORSF is a novel causal lncRNA for sow fertility traits in QTLs. QTLs are characterized for sow fertility traits at the genome-wide level and identified 4,630 potential candidate lncRNAs, with 13 differentially expressed during sow follicular atresia. NORSF, a lncRNA that involved in sow granulosa cell (sGC) function, is identified as a candidate gene for sow fertility traits as a G to A transversion at 128 nt in its transcript is shown to be markedly associated with sow fertility traits. Mechanistically, after forming the RNA:dsDNA triplexes with the promoter of Caspase8, NORSF transcript with allele G binds to an RNA-binding protein (RBP) NR2C1 and recruits it to the promoter of Caspase8, to induce Caspase8 transcription in sGCs. Functionally, this leads to a loss of inducing effect of NORSF on sGC apoptosis by inactivating the death receptor-mediated apoptotic pathway. This study identified a novel causal lncRNA that can be used for the genetic improvement of sow fertility traits.

Fabová Z, Loncová B, Harrath AH, Sirotkin AV. Involvement of circular RNAs in the control of porcine ovarian cell functions: Upregulation by ciR-00596 and downregulation by ciR-00646. Reprod Biol 2024; 24:100860. [PMID: 38762967 DOI: 10.1016/j.repbio.2024.100860] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/06/2023] [Revised: 01/24/2024] [Accepted: 01/31/2024] [Indexed: 05/21/2024]
Abstract
The current understanding of the role of circular RNAs (circRNAs) in regulating ovarian functions is inadequate. To assess the impact of ciR-00596 and ciR-00646 on the regulation of basic porcine ovarian granulosa cell functions, we conducted upregulation (utilizing overexpressing vectors) and downregulation (utilizing shRNA vectors) of these circRNAs. The relative expression of both circRNAs, cell viability and proliferation (accumulation of PCNA, cyclin B1, and XTT-positive cells), cytoplasmic (accumulation of bax and caspase-3) and nuclear (DNA fragmentation) apoptosis, and the release of progesterone, testosterone, estradiol, IGF-I, and oxytocin were evaluated. Transfection of cells with the ciR-00596 overexpression vector resulted in increases in cell viability and proliferation and the release of progesterone and IGF-I, while it decreased the cytoplasmic and nuclear apoptosis, testosterone, estradiol, and oxytocin output. CiR-00596 inhibition had the opposite effects. The overexpression of ciR-00646 decreased cell viability and proliferation, and the release of progesterone, IGF-I, and oxytocin, while increasing cytoplasmic and nuclear apoptosis and the output of testosterone and estradiol. Our findings are the first to show the stimulatory action of ciR-00596 and the inhibitory effect of ciR-00646 on ovarian cell functions, including the cell cycle, apoptosis, and secretory activity.

Theriogenology 2023; 205:50-62. [PMID: 37086585 DOI: 10.1016/j.theriogenology.2023.04.013] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/27/2022] [Revised: 03/23/2023] [Accepted: 04/14/2023] [Indexed: 04/24/2023]
Abstract
MicroRNAs (miRNAs) are involved in many physiological processes such as signal transduction, cell proliferation and apoptosis. Many studies have shown that miRNAs can regulate the process of follicular development. Our previous studies found that the expression of miR-29c-5p in buffalo atretic follicles was much higher than that in healthy follicles, suggesting that this miRNA may participate in the process of buffalo follicular atresia. In this study, we aim to explore to the role and molecular mechanisms of miR-29c-5p on the functions of buffalo granulosa cells (GCs). GCs cultured in vitro were transfected with miR-29c-5p mimics and its inhibitor, respectively, and it was found that the mimics significantly increased the apoptotic rate of GCs. They also inhibited the proliferation of GCs and the secretion of steroid hormones. The effect of the inhibitor was opposite to that of the mimics. MiR-29c-5p was subsequently shown to target the inhibin subunit beta A, (INHBA). Overexpression of INHBA could promote the production of activin A and inhibin A, and then reverse the effect of miR-29c-5p on buffalo GCs. In conclusion, these results suggest that miR-29c-5p promotes apoptosis and inhibits proliferation and steroidogenesis by targeting INHBA in buffalo GCs. This may ultimately promote atresia in buffalo follicles.

Abstract
The FecB mutation in the sheep BMPRIB is strongly correlated with high ovulation traits but its mechanism remains unclear. This study explored differentially expressed genes (DEGs) and their associated molecular mechanisms that may be involved in FecB mutation-induced high ovulation from the perspective of the hypothalamic-pituitary-gonadal (HPG) axis by conducting a systematic review and meta-analysis. The PubMed, EMBASE, CNKI, WanFang, and CBM databases were searched for eligible articles published before August 2022, focusing on mRNA sequencing of different tissues in the HPG axis in sheep with different FecB genotypes. A total of 6555 DEGs were identified from the analysis of six published articles and experimental results from our laboratory. The DEGs were screened by vote-counting rank and robust rank aggregation. Among these, in the follicular phase, FKBP5, CDCA7 and CRABP1 were upregulated in the hypothalamus. INSM2 was upregulated, while LDB3 was downregulated in the pituitary. CLU, SERPINA14, PENK, INHA and STAR were upregulated, while FERMT2 and NPY1R were downregulated in the ovary. On the HPG axis, TAC1 was upregulated and NPNT was downregulated. Many DEGs were found in sheep with different FecB genotypes. The genes FKBP5, CDCA7, CRABP1, INSM2, LDB3, CLU, SERPINA14, PENK, INHA, STAR, FERMT2, NPY1R, TAC1 and NPNT, may be associated with FecB mutation-induced high ovulation in different tissues. These candidate genes will further improve the mechanism of multiple fertility traits induced by the FecB mutation from the perspective of the HPG axis.

Abstract
Egg production is a vital biological and economic trait for poultry breeding. The 'hypothalamic-pituitary-ovarian (HPO) axis' determines the egg production, which affects the layer hens industry income. At the organism level, the HPO axis is influenced by the factors related to metabolic and nutritional status, environment, and genetics, whereas at the cellular and molecular levels, the HPO axis is influenced by the factors related to endocrine and metabolic regulation, cytokines, key genes, signaling pathways, post-transcriptional processing, and epigenetic modifications. MiRNAs and lncRNAs play a critical role in follicle selection and development, atresia, and ovulation in layer hens; in particular, miRNA is known to affect the development and atresia of follicles by regulating apoptosis and autophagy of granulosa cells. The current review elaborates on the regulation of the HPO axis and its role in the laying performance of hens at the organism, cellular, and molecular levels. In addition, this review provides an overview of the interactive network regulation mechanism of the HPO axis in layer hens, as well as comprehensive knowledge for successfully utilizing their genetic resources.

Abstract
The ovary is a female reproductive organ that plays a key role in fertility and the maintenance of endocrine homeostasis, which is of great importance to women's health. It is characterized by a high heterogeneity, with different cellular subpopulations primarily containing oocytes, granulosa cells, stromal cells, endothelial cells, vascular smooth muscle cells, and diverse immune cell types. Each has unique and important functions. From the fetal period to old age, the ovary experiences continuous structural and functional changes, with the gene expression of each cell type undergoing dramatic changes. In addition, ovarian development strongly relies on the communication between germ and somatic cells. Compared to traditional bulk RNA sequencing techniques, the single-cell RNA sequencing (scRNA-seq) approach has substantial advantages in analyzing individual cells within an ever-changing and complicated tissue, classifying them into cell types, characterizing single cells, delineating the cellular developmental trajectory, and studying cell-to-cell interactions. In this review, we present single-cell transcriptome mapping of the ovary, summarize the characteristics of the important constituent cells of the ovary and the critical cellular developmental processes, and describe key signaling pathways for cell-to-cell communication in the ovary, as revealed by scRNA-seq. This review will undoubtedly improve our understanding of the characteristics of ovarian cells and development, thus enabling the identification of novel therapeutic targets for ovarian-related diseases.

Abstract
Circular RNAs (circRNAs) are an abundant class of endogenous non-coding RNAs (ncRNAs) generated from exonic, intronic, or untranslated regions of protein-coding genes or intergenic regions. The diverse, stable, and specific expression patterns of circRNAs and their possible functions through cis/trans regulation and protein-coding mechanisms make circRNA a research hotspot in various biological and pathological processes. It also shows practical value as biomarkers, diagnostic indicators, and therapeutic targets. This review summarized the characteristics, classification, biogenesis and elimination, detection and confirmation, and functions of circRNAs. We focused on research advances circRNAs in the mammalian ovary under conditions including ovarian cancer, polycystic ovarian syndrome (PCOS), and maternal aging, as well as during reproductive status, including ovarian follicle development and atresia. The roles of circRNAs in high reproductive traits in domestic animals were also summarized. Finally, we outlined some obstructive factors and prospects to work with circRNA, aiming to provide insights into the functional research interests of circRNAs in the reproduction and gynecology areas.

Abstract
The high level of progesterone and 17β-estradiol ratio (P4/E2) in follicular fluid has been considered as a biomarker of follicular atresia. CYP11A1, the crucial gene encoding the rate-limiting enzyme for steroid hormone synthesis, has been reported differently expressed in the ovary during follicular atresia. However, the regulation mechanism of CYP11A1 expression during follicular atresia still remains unclear. Here, we have demonstrated that lnc2300, a novel pig ovary-specific highly expressed cis-acting long noncoding RNA (lncRNA) transcribed from chromosome 7, has the ability to induce the expression of CYP11A1 and inhibit the apoptosis of porcine granulosa cells (GCs). Mechanistically, lnc2300, mainly located in the cytoplasm of porcine GCs, sponges and suppresses the expression of miR-365-3p through acting as a competing endogenous RNA (ceRNA), which further relieves the inhibitory effects of miR-365-3p on the expression of CYP11A1. Besides, CYP11A1 is validated as a direct functional target of miR-365-3p in porcine GCs. Functionally, lnc2300 is an antiapoptotic lncRNA that reduces porcine GC apoptosis by inhibiting the proapoptotic function of miR-365-3p. In summary, our findings reveal a cis-acting regulation mechanism of CYP11A1 through lncRNA, and define a novel signaling pathway, lnc2300/miR-365-3p/CYP11A1 axis, which is involved in the regulation of GC apoptosis and follicular atresia.
