Roxadustat in the treatment of anaemia in chronic kidney disease

816 views | Mar 31 2019

Del Vecchio L et al showed that Roxadustat is a chemical drug and thus has the potential of being cheaper than traditional ESAs. Given that the peaks of endogenous EPO are much lower than those observed with traditional ESA, it is possible to speculate the roxadustat (and more in general PHD inhibitors) will be safer than ESA on cardiovascular safety end-points. Considering that HIFs are involved in different pathways, with possible promotion of relevant side effects, their safety must be proven in long-term studies. [Read the Full Post]

Mechanisms of U46619-induced contraction in mice intrarenal arteries

1297 views | Mar 27 2019

Yan H et al. suggested that the U46619-induced contraction of mouse intrarenal arteries is mediated by Cav1.2 and SOC channel, through the activation of thromboxane-prostanoid receptors and its downstream signaling pathway. [Read the Full Post]

The Sirt1 activator, SRT1720, attenuates renal fibrosis by inhibiting CTGF and oxidative stress

794 views | Mar 24 2019

Ren Y et al. indicated that the Sirt1 activator, SRT1720, exerts protective effects against UUO-induced tubulointerstitial fibrosis. The mechanisms of action of SRT1720 may include, at least in part, the suppression of renal oxidative stress and the TGF-β1/CTGF signalling pathway. The Sirt1 activator may therefore be prove to be a potent therapeutic agent for the treatment of fibrotic kidney disease. [Read the Full Post]
