Proteomic analysis of the zone of degeneration at the mitosis–meiosis transition stage in wild‐caught male catshark (Scyliorhinus canicula), correlated with an unusually high‐water temperature in the English Channel

Journal of Fish Biology, EarlyView.
Abstract In the context of current global change, variations in water temperature are one of the environmental conditions with serious consequences for marine life, including reproductive processes. In the small spotted catshark Scyliorhinus canicula, spermatogenesis occurs in spermatocysts composed of synchronously developing germ cells associated ...

Steroid Hormones Are Potent and Putatively Endogenous Activators of Human Bitter Taste Receptors

Annals of the New York Academy of Sciences, EarlyView.
Human bitter taste receptors are not only involved in sensing tastants within the oral cavity but also play crucial roles in internal tissues of the body. The current report identifies numerous structurally and functionally diverse steroid hormones as activators of the two human bitter taste receptors, TAS2R14 and TAS2R46.

Antenatal betamethasone impairs markers of cardiac development and function in near‐term lambs

Experimental Physiology, EarlyView.
Abstract figure Summary of key molecular differences in the left ventricle of near‐term lambs exposed to antenatal betamethasone, compared to saline. Pregnant ewes received two doses of either saline (Saline) or betamethasone (Betamethasone, intramuscular, 11.4 mg) given 24 h apart, before delivery at 140 days of gestation (dG, term = 150 dG).
