Connecting glucose signalling to ubiquitin-dependent transporter endocytosis : ...

A metabolic switch on a yeast arrestin connects glucose signaling to transporte...

Endocytosis is a critical component of plasma membrane dynamics, by allowing the removal of proteins such as transporters or receptors in response to environmental cues. In yeast, transporter endocytosis requires their ubiquitylation at the plasma membrane by the Nedd4-like E3 ubiquitin ligase, Rsp5. Since the ubiquitylation of a given transporter occurs only in response to specific signals, this raises the que...

Modulatory activity of antioxidants against the toxicity of Rifampicin in vivo

The World Health Organization (WHO) has shown concern about the burden of tuberculosis in the developing countries. Even though rifampicin is an effective drug in the management of tuberculosis, it has been documented to have some toxic effects in humans. Therefore, this study intends to investigate the modulatory effect of vitamins C and E on the hepatotoxicity, sperm quality and brain toxicity of Rifampicin. ...
