In this study, we explored Q-3-Dec as a multi-target agent, which concomitantly impairs NF-κB/STAT3-dependent survival signaling, mitochondrial function, and O6-Methylguanine-DNA Methyltransferase (MGMT) expression, a DNA repair enzyme closely associated with chemoresistance, in glioma cells. The gene discussed is LIG4; the disease is central nervous system cancer.
