Resveratrol restores sensitivity of glioma cells to temozolamide through inhibiting the activation of Wnt signaling pathway.

Malignant gliomas are aggressive primary neoplasms that originate in the glial cells of the brain or the spine with notable resistance to standard treatment options. We carried out the study with the aim to shed light on the sensitization of resveratrol to temozolomide (TMZ) against glioma through the Wnt signaling pathway. Initially, glioma cell lines with strong resistance to TMZ were selected by 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide (MTT) assay.

MicroRNA-499a decelerates glioma cell proliferation while accelerating apoptosis through the suppression of Notch1 and the MAPK signaling pathway.

As the most common and lethal of intracranial tumors, glioma accounts for 81% of all malignant brain tumors. Research data have identified the role of microRNAs (miRs) as functional suppressors in the progression of Glioma. The present study aimed to, ascertain as to whether microRNA-499a (miR-499a) influences cell proliferation and apoptosis through the MAPK signaling pathway by targeting Notch1 in glioma.
