procyanidin a 2/hypoxia

Hypoxia-inducible factor-1 (HIF-1) is over-expressed in gliomas and has become one of the most compelling tumor targets. In this study, we found that oligomer procyanidins (F2) can suppress the expressions of HIF-1α and its target genes in U87 cells, and also down-regulate the EGFR/PI3K/AKT/mTOR and

Overexpression of hypoxia-inducible factor-1 (HIF-1) α, a transcription factor which immortalizes tumors by inducing expression of the genes involved in cell survival, migration and angiogenesis, is closely associated with poor prognosis, increased risk of metastasis and increased mortality.

Procyanidins are polyphenols with antioxidant, anti-obesity, and anti-inflammatory properties. Procyanidin B2 (PCB2) gallate; specifically, PCB2 3,3''-di-O-gallate (PCB2DG), inhibits cytokine production in T cells. However, the molecular interactions and partners of PCB2DG underlying this

Hypoxia-induced oxidative stress and excessive proliferation of pulmonary artery smooth muscle cells (PASMCs) play important roles in the pathological process of hypoxic pulmonary hypertension (HPH). Grape seed procyanidin extract (GSPE) possesses antioxidant properties and has beneficial effects on

OBJECTIVE To study the direct effect of hawthorn leaf procyanidins on cardiomyocytes subjected to ischemia-reperfusion injury and elucidate their therapeutic mechanism on ischemic heart diseases. METHODS Cultured cardiomyocytes of neonatal rats were subjected to anoxia-reoxia injury which simulated
