Granulosa cell abnormalities are characteristics of premature ovarian insufficiency (POI). Abnormal expression of serine/arginine-rich splicing factor 1 (SRSF1) can cause various diseases, but the role of SRSF1 in mouse granulosa cells remains largely unclear. In this study, we found that SRSF1 was expressed in the nuclei of both mouse oocytes and granulosa cells. The specific knockout of Srsf1 in granulosa cells led to follicular development inhibition, decreased granulosa cell proliferation, and increased apoptosis. Gene Ontology (GO) analysis of RNA-seq results revealed abnormal expression of genes involved in DNA repair, cell killing and other signalling pathways. Alternative splicing (AS) analysis showed that SRSF1 affected DNA damage in granulosa cells by regulating genes related to DNA repair. In summary, SRSF1 in granulosa cells controls follicular development by regulating AS of genes associated with DNA repair, thereby affecting female reproduction.

Purpose: To investigate the protective effect of sub-hypothermic mechanical perfusion combined with membrane lung oxygenation on ischemic hypoxic injury of yorkshire brain tissue caused by traumatic blood loss.
Methods: This article performed a random controlled trial. Brain tissue of 7 yorkshire was selected and divided into the sub-low temperature anterograde machine perfusion group (n = 4) and the blank control group (n = 3) using the random number table method.

Backgrounds: Recent studies have found Several lncRNAs were proved differential expression in diminished ovarian reserve (DOR) patients, however, the mechanism of DOR caused by lncRNAs is still largely unclear.
Methods: High throughput sequencing was performed in ovarian GCs extracted from women with normal ovarian function and women with DOR. Bioinformation analysis was used to analyze the sequencing data and identify the differential expression of lncRNAs.

During ovary development, the dormant primordial follicles (PF) are stimulated and begin to develop into primary follicles (PrF), a process called follicle activation. Only activated follicles can continue to grow and release the eggs in the future, making the female animal fertile. The molecular events during PF activation are not fully understood.

Chronic stress can adversely affect the female reproductive endocrine system, potentially leading to disorders and impairments in ovarian function. However, current research lacks comprehensive understanding regarding the biochemical characteristics and underlying mechanisms of ovarian damage induced by chronic stress. We established a stable chronic unpredictable stress (CUS)-induced diminished ovarian reserve (DOR) animal model.

(AMK) as an oriental medicine has been used in the treatment of threatened abortion. (AT-I) is one of the major bioactive components of AMK. This study aimed to investigate the effect of AT-I on the secretion of estradiol (E) and progesterone (P) in feline ovarian granulosa cells (FOGCs), which is necessary for pregnancy.
