A possible relationship between transforming growth factor beta receptor type I (TbetaRI) and type II (TbetaRII) protein expression in human granulosa cells and the quality of preimplantation embryo development in vitro was studied using immunoblot analysis of TbetaRI and TbetaRII in hyperstimulated granulosa cells and morphological assessment of the cleavage potential of the zygotes in vitro. Washed granulosa cells were collected from

As one of the essential lignan derivative found in traditional Chinese medicinal herbs, secoisolariciresinol diglucoside (SDG) was proved to promote women's health through its phytoestrogenic properties. Increasingly studies indicated that this compound could be a potential drug capable of preventing estrogen-related diseases. Here, we aimed to investigate whether SDG can counteract cyclophosphamide (CTX) induced premature ovarian insufficiency (POI) and further explore its specific molecular mechanism.

We hypothesized that human chorionic gonadotropic (hCG) could replace LH in the maturation media for buffalo oocytes, and hCG administration before ovum pick-up (OPU) enhances in-vitro development of buffalo oocytes. Objectives were 1) to investigate the effect of hCG supplementation on nuclear maturation, oocyte development, and granulosa cell mRNA abundance of genes related to growth and antioxidant pathways and 2) to determine the effect of hCG administration before OPU on in-vitro oocyte development. In Experiment 1, buffalo oocytes retrieved from slaughterhouse ovaries were maturated in the media supplemented with 0.

Forkhead box L2 (FOXL2) encodes a transcription factor essential for sex determination, and ovary development and maintenance. Mutations in this gene are implicated in syndromes involving premature ovarian failure and granulosa cell tumors (GCTs). This rare cancer accounts for less than 5% of diagnosed ovarian cancers and is causally associated with the FOXL2 c.

Objective: Polycystic ovary syndrome (PCOS) is a reproductive endocrine disease characterized by reproductive dysfunction and metabolic abnormalities. The purpose of this study was to explore the expression characteristics of coding and non-coding RNAs in granulosa cells of PCOS, and to provide data support for understanding the pathogenesis of PCOS.
Methods: Three patients with PCOS (according to the 2003 Rotterdam diagnostic criteria) and three normal controls were selected.

N-(1,3-dimethylbutyl)-N'-phenyl-p-phenylenediamine-quinone (6PPD-Q), an environmental pollutant derived from the ozonolysis of the widely used tire rubber antioxidant 6PPD, has been found to accumulate in air, dust, and water, posing significant health risks. While its reproductive toxicity in male organisms has been established, its effects on female reproductive health remain unclear. Polycystic ovary syndrome (PCOS), a common endocrine disorder in premenopausal women, is known to be influenced by environmental pollutants.
