Deposition of amyloid-β (Aβ) peptides into specific encephalic structures has been pointed as an important event related to Alzheimer’s disease pathogenesis and associated with activation of glial cells, neuroinflammation, oxidative responses, and cognitive deficits. Aβ-induced pro-oxidative damage may regulate the activity of glutamate transporters,(More)
Glioblastoma multiforme is the main and most frequent tumor in adults' central nervous system. With a survival average of 5% two years after diagnosis, this type of cancer is a main health problem. Substances like the chalcones have been tested in order to develop new treatments. Here, we studied the effects of three synthetic chalcones (A23, C31 and J11)(More)
Gliomas are a malignant tumor group whose patients have survival rates around 12 months. Among the treatments are the alkylating agents as temozolomide (TMZ), although gliomas have shown multiple resistance mechanisms for chemotherapy. Guanosine (GUO) is an endogenous nucleoside involved in extracellular signaling that presents neuroprotective effects and(More)
Malignant gliomas have resistance mechanisms to chemotherapy that enable tumor invasiveness and aggressiveness. Alternative therapies in cancer treatment, as statins, have been suggested to decrease proliferation, inhibit cell migration, and induce cell death. The aim of this study was to evaluate the effect of atorvastatin (ATOR) on cell viability,(More)
