phenethyl isothiocyanate/hypoxia

Phenethyl isothiocyanate (PEITC), a natural dietary isothiocyanate, has anti-cancer activity in various in vitro and in vivo models. PEITC inhibits angiogenesis but the molecular mechanisms that underlie this effect are not known. We have now demonstrated that PEITC is an effective inhibitor of

Phenethyl isothiocyanate (PEITC), a natural dietary isothiocyanate, inhibits angiogenesis but the molecular mechanisms that underlie this effect are not known. In this study, under hypoxic conditions (1% O2), we examined the effect of PEITC on the intracellular level of the hypoxia inducible factor

Hypoxia occurs frequently in various solid tumors and elicits a cellular response designed to improve cell survival through adaptive processes, thereby accelerating cancer progression and the development of chemotherapy resistance. Tumor necrosis factor-related apoptosis-inducing ligand (TRAIL), a

Hypoxia-inducible factor 1α (HIF-1α) plays a crucial role in facilitating tumor progression and metastasis. Reducing the levels of HIF-1α might therefore be an important anticancer strategy. This could be achieved by understanding the key cellular events involved in HIF-1α activation. Present study

The transcription factor hypoxia-inducible factor-1 (HIF-1) consists of oxygen-sensitive HIF-1α and constitutive HIF-1β. HIF-1α is undetectable in normal cells, but cancer cells frequently express HIF-1α to support their growth, angiogenesis, and high glycolysis (also known as the Warburg effect).
