Background: This study was conducted to evaluate fibroblast co-culture and Activin A on in vitro maturation and fertilization of mouse preantral follicles. Methods: The ovaries from 12-14-day-old mice were dissected, and 120-150 μm preantral follicles were cultured individually in α-MEM as based medium for 12 days. A total number of 456 follicles were cultured in four conditions: (i) base mediu...

Activin A is a member of the transforming growth factor β super family. Because of its extensive clinical usages, its recombinant production is beneficial. In this study, activin A was expressed in E. coli using the pET 21a expression vector. The optimization of the activin A production in E. coli was done by using the response surface methodology (RSM). At this stage, the effect of IPTG and la...

Abstract Background Activins are members of the transforming growth factor-? superfamily implicated in pathogenesis several immunoinflammatory disorders. Based on our previous studies demonstrating that overexpression activin-A murine lung causes pathology sharing key features coronavirus disease 2019 (COVID-19), we hypothesized activins and their natural inhibitor follistatin might be particul...

Background & Aims: The aim of this study was to assess the effect of core stabilization exercise on the serum level of Activin A and back performance scale in elderly women. Materials & Methods: This study was a semi-experimental research. Eighteen volunteer women with low back pain (age 69.1±2.45 years, body mass index 25.5±2.84 kg/m2 and fat percentage 33.7±2.95%) were randomly divided into ...

The activin/follistatin system is implicated in growth and differentiation of various cell types. Follistatin (FS), through binding and neutralizing activin, plays a major role in the regulation of activin bioavailability. We previously reported that ovarian PA1 cells constitutively secrete FS and show a decreased proliferation rate in response to exogenous activin only if cell surface associat...

The effect of activins AB and B on DNA synthesis stimulated by epidermal growth factor (EGF) was studied in primary cultured rat hepatocytes and compared with the effect of activin A, a suppressor of DNA synthesis. Activin AB inhibited DNA synthesis as assessed by [3H]thymidine incorporation. The inhibition by activin AB was detected at 6 ng/ml, and the 12.5 ng/ml concentration produced almost ...

Deregulated expression of activin A is reported in several tumors, but its biological functions in oral squamous cell carcinoma (OSCC) are unknown. Here, we investigate whether activin A can play a causal role in OSCCs. Activin A expression was assessed by qPCR and immunohistochemistry in OSCC tissues. Low activin A-expressing cells were treated with recombinant activin A and assessed for apopt...
