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

Oligomer procyanidins (F2) isolated from grape seeds inhibits tumor angiogenesis and cell invasion by targeting HIF-1α in vitro.

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.

Procyanidin B2 gallate regulates TNF-α production from T cells through inhibiting glycolytic activity via mTOR-HIF-1 pathway.

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

Grape seed procyanidin extract attenuates hypoxic pulmonary hypertension by inhibiting oxidative stress and pulmonary arterial smooth muscle cells proliferation.

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
