Role of resistin in the porcine uterus: effects on endometrial steroidogenesis.

Context The adipose tissue produces adipokines - hormones essential to many biological functions, including reproduction. Aims We hypothesised that resistin, one of the adipokines, is present in the blood plasma, uterine luminal flushings (ULF) and uterus of pigs during the oestrous cycle and early pregnancy, and that resistin influences uterine steroidogenesis. Methods This study aimed to determine the expression of resistin in the porcine endometrium and myometrium during the cycle and pregnancy by quantitative real-time polymerase chain reaction and western blot (WB).

Acupuncture and traditional Chinese medicine (TCM) have shown certain benefits in assisted in vitro fertilization and embryo transfer (IVF-ET). In this study, we evaluated the efficacy and safety of the combination of acupuncture combined with the Bushen Quyu decoction in patients with failures of IVF-ET. This study was conducted at Shanghai Yangpu District Hospital of TCM from May to November of 2021.

Patients And Methods: Materials and Methods: To test our hypothesis, this case-control study consisted of 20 healthy donors (control group); 49 patients with a positive diagnosis of COVID-19 according to PCR analysis; 15 patients with a positive diagnosis of COVID-19 in combination with renal cell cancer; 29 patients with a positive diagnosis of COVID-19 in combination with critical limb ischemia, 10 pregnant womens with COVID-19.
In Brief: PI3K-AKT signaling activates steroidogenesis by inducing estradiol and progesterone production, while MEK-ERK1/2 signaling regulates steroidogenesis by inhibiting estradiol and inducing progesterone production in granulosa cells (GCs). Both pathways are essential for glycolytic and mitochondrial metabolism in these cells.
Abstract: The PI3K-AKT and MEK-ERK1/2 signaling pathways are integral to fundamental cellular processes, such as proliferation, viability and differentiation.
Article Synopsis
- Determining progesterone levels in mares' serum is crucial for identifying issues related to their estrus cycle or luteal insufficiency, but current methods lack quick, accurate results within two hours.
- This study assesses the effectiveness of the mini VIDAS device, a commercial enzyme-linked fluorescent assay, against the traditional radioimmunoassay (RIA) for progesterone measurement in mares.
- Results indicate a strong correlation between mini VIDAS and RIA measurements; however, the mini VIDAS may have limitations in precision at lower progesterone levels, which could affect diagnostic accuracy.
