Abstract
Background: Caffeine represents the most used psychoactive drug in the world acting through different mechanisms of action and on several molecular targets. It exerts an anti-cancer role in glioblastoma multiforme (GBM). This neoplasia is characterized by extensive hypoxic foci triggering hypoxia-inducible factors (HIFs) expression. Among these factors, HIF-1α performs a crucial role in the induction of vascular endothelium growth factor (VEGF), a key player in angiogenesis and cell migration.
Methods: In this work, we have investigated whether caffeine counteracts GBM progression by modulating hypoxic event. Moreover, we analyzed the activation of phosphoinositide three kinase (PI3K)/Akt and mammalian mitogen activated protein kinase/Erk kinase (MAPK/ERK) signaling cascades.
Results: Our results have indicated that this psychostimulant drug significantly reduced HIF-1α and VEGF expression in GBM cells exposed to hypoxia. This effect is mediated through inhibition of PI3K/Akt and MAPK/ERK signaling pathways both implied in HIFs regulation.
Conclusion: The present data give new insight into antitumor activity of caffeine during GBM progression.
Keywords: Caffeine, glioblastoma multiforme, hypoxia-inducible factors, vascular endothelium growth factor, PI3K/Akt, MAPK/ERK.

Induction of cell death in cancer cells by modulating telomerase activity using small molecule drugs
Telomeres are distinctive but short stretches present at the corners of chromosomes and aid in stabilizing chromosomal makeup. Resynthesis of telomeres supported by the activity of reverse transcriptase ribonucleoprotein complex telomerase. There is no any telomerase activity in human somatic cells, but the stem cells and germ cells undergone telomerase ...read more
