BRD7 mediates hyperglycaemia-induced myocardial apoptosis via endoplasmic reticulum stress signalling pathway.

Bromodomain-containing protein 7 (BRD7) is a tumour suppressor that is known to regulate many pathological processes including cell growth, apoptosis and cell cycle. Endoplasmic reticulum (ER) stress-induced apoptosis plays a key role in diabetic cardiomyopathy (DCM). However, the molecular mechanism of hyperglycaemia-induced myocardial apoptosis is still unclear.

HMGB1 mediates hyperglycaemia-induced cardiomyocyte apoptosis via ERK/Ets-1 signalling pathway.

Apoptosis is a key event involved in diabetic cardiomyopathy. The expression of high mobility group box 1 protein (HMGB1) is up-regulated in diabetic mice. However, the molecular mechanism of high glucose (HG)-induced cardiomyocyte apoptosis remains obscure.

[Regulation of p14(ARF) expression and induction of cell apoptosis with c-myc in a p53-independent pathway].

Objective: To explore the regulation of p14(ARF) expression and induction of cell apoptosis with the mutant and wild-type c-myc genes in a p53-independent pathway of signal transduction.

Methods: The mutant and wild-type c-myc genes were transfected by lentivirus into HCC1937 to form the stable over-expression cell lines. Uninfected cells and lentivirus-infected ones carrying no c-myc gene acted as blank and infection controls respectively.

Protective effects of Salvia plebeia compound homoplantaginin on hepatocyte injury.

Salvia plebeia R. Br is a traditional Chinese herb which has been considered as an inflammatory mediator used for treatment of many infectious diseases including hepatitis. Previously, the compound homoplantaginin was isolated in our group.
