Besides giving structural support, Sertoli cells regulate the fate of germ cells by supplying a variety of factors. These factors include hormones, several pro- and anti-apoptotic agents and also energetic substrates. Lactate is one of the compounds produced by Sertoli cells, which is utilized as an energetic substrate by germ cells, particularly(More)
The effects of dopamine (DA) and dopaminergic agonists and antagonists on ion transport were studied in isolated perfused gills of the crab Chasmagnathus granulatus. DA applied under steady state conditions (perfusion with hemolymph-like saline) produced a transient increase of the transepithelial potential difference (V(te)) from 2.2+/-0.2 to 4.8+/-0.3 mV,(More)
The purpose of this study was to evaluate the existence of a possible simultaneous regulation of fatty acid (FA) metabolism and lactate production by PPAR α and PPAR β/δ activation in Sertoli cells (SC). SC cultures obtained from 20-day-old rats were incubated with WY14643 or GW0742-pharmacological activators of PPAR α and PPAR β/δ respectively. The fatty(More)
