Shen-Qi-Di-Huang Decoction induces autophagy in podocytes to ameliorate membranous nephropathy by suppressing USP14.

Ethnopharmacological Relevance: Shen-Qi-Di-Huang decoction (SQDHD) is a renowned decoction in traditional Chinese medicine, dating back to the Qing Dynasty. SQDHD has been widely applied in treating renal diseases, including Membranous nephropathy (MN), with its proven positive clinical outcomes. Nevertheless, the precise mechanism by which SQDHD exerts its therapeutic effects on MN remains uncertain.

Astragaloside IV relieves passive heymann nephritis and podocyte injury by suppressing the TRAF6/NF-κb axis.

The pathogenesis of membranous nephropathy (MN) involves podocyte injury that is attributed to inflammatory responses induced by local immune deposits. Astragaloside IV (AS-IV) is known for its robust anti-inflammatory properties. Here, we investigated the effects of AS-IV on passive Heymann nephritis (PHN) rats and TNF-α-induced podocytes to determine the underlying molecular mechanisms of MN.

Fangji Huangqi decoction ameliorates membranous nephropathy through the upregulation of BNIP3-mediated mitophagy.

Ethnopharmacological Relevance: Fangji Huangqi Decoction (FJHQ), a traditional Chinese medicinal formula outlined in Zhang Zhongjing's "Jin Gui Yao Lue" during the Han Dynasty, is often used to treat conditions characterized by symptoms like edema and dysuria, including membranous nephropathy (MN). Despite its proven clinical effectiveness, the exact mechanisms through which FJHQ acts on MN remain elusive.

Aim Of The Study: This study aimed to investigate whether FJHQ enhances BNIP3-mediated mitophagy in podocytes by promoting BNIP3 expression and whether this improvement leads to the amelioration of MN.

Revealing conformational dynamics of 2'-O-methyl-RNA guanine modified G-quadruplex by replica exchange molecular dynamics.

Thrombin-binding DNA aptamer (TBA) can fold into an antiparallel unimolecular G-quadruplex (G4) structure. Different types of modifications lead to various effects on the structure and stability of the G4 structure. Previous study has shown that a modified TBA (mTBA) that 2'-deoxy guanine (dG) at positions 10 and 11 in the TBA sequence were replaced by 2'-O-methyl-RNA guanine (2'OMe-G) can't fold into a well-defined G4 structure.

Synthesis, in vitro and in vivo biological evaluation, docking studies, and structure--activity relationship (SAR) discussion of dipeptidyl boronic acid proteasome inhibitors composed of beta-amino acids.

A series of novel dipeptidyl boronic acid proteasome inhibitors composed of beta-amino acids were synthesized, in vitro and in vivo biologically evaluated, and theoretically modeled for the first time. From the screened racemic compounds in enzyme, 4i was the most active. The IC(50) value of its pure enantiomer 4q was 9.
