Identification of ActivinβA and Gonadotropin Regulation of the Activin System in the Ovary of Chinese Sturgeon Acipenser sinensis

Animals
Activin is a dimeric growth factor with diverse biological activities in vertebrates. This study aimed to investigate the regulatory role of the activin signaling pathway in the ovary of the endangered, cultured sturgeon species Acipenser sinensis.

Follicle Stimulating Hormone in Cattle Breeding: Fundamentals, Innovations, and Scope

Animal Research and One Health, EarlyView.
FSH is crucial in cattle reproduction, with exogenous administration enhancing breeding and embryo production. Recombinant FSH offers advantages over pituitary‐extracted variants, including fewer injections, reduced stress, and safer production. These innovations improve breeding efficiency, optimize reproductive outcomes, and contribute to sustainable

Phylogenomic analyses reveal the evolutionary origin of the inhibin alpha-subunit, a unique TGFbeta superfamily antagonist. [PDF]

PLoS ONE, 2010
Transforming growth factor-beta (TGFbeta) homologues form a diverse superfamily that arose early in animal evolution and control cellular function through membrane-spanning, conserved serine-threonine kinases (RII and RI receptors).

Activin receptor 2A and activin receptor 2B genes in chicken: effect on carcass traits

Journal of Applied Animal Research, 2015
Carcass traits are of immense importance in chicken as some parts of the carcass particularly breast muscle and legs are mostly preferred by the consumers with good market price while the remaining parts have a lower price. Carcass traits primarily depend on the growth of the birds, which are controlled by the candidate genes.

Microbial Hydrolysates as Amino Acid Source in Cell Culture Media for Cellular Agriculture

Biotechnology and Bioengineering, EarlyView.
ABSTRACT The high cost of cultivation media remains one of the barriers to the commercialization of cultivated meat. Current serum‐free media reduce reliance on fetal bovine serum but only achieve modest cost savings. Especially at larger scales (> 20 m3), pharmaceutical‐grade amino acids and recombinant proteins remain major cost drivers.

Mitochondria‐endoplasmic reticulum organelle glue as maturation promoter for origination/dimensional dual‐cross cardiomyocytes

BMEMat, EarlyView.
Mitochondria‐endoplasmic reticulum contact sites (MERCS) are areas where the mitochondria and endoplasmic reticulum closely interact. In this study, we utilize synthetic organelle glues to artificially engineer MERCS for regulating cardiomyocyte development, through which the immature and chemo‐plasticity issues of undifferentiated cells are addressed.

Physiological roles of activins in the human ovary

Journal of Bio-X Research, 2018
. Initially discovered in the pituitary as stimulators of follicle stimulating hormone, activins are homo- or heterodimers of inhibin subunits, which belong to the transforming growth factor-β superfamily.

WNT4/beta-catenin pathway maintains female germ cell survival by inhibiting activin betaB in the mouse fetal ovary. [PDF]

PLoS ONE, 2010
Female germ cells are essential for organogenesis of the ovary; without them, ovarian follicles do not form and functional and structural characteristics of the ovary are lost.

Systemic aging fuels heart failure: Molecular mechanisms and therapeutic avenues

ESC Heart Failure, Volume 12, Issue 2, Page 1059-1080, April 2025.
Abstract Systemic aging influences various physiological processes and contributes to structural and functional decline in cardiac tissue. These alterations include an increased incidence of left ventricular hypertrophy, a decline in left ventricular diastolic function, left atrial dilation, atrial fibrillation, myocardial fibrosis and cardiac ...
