P-Glycoprotein Drives Glioblastoma Survival and Chemotherapy Resistance: Potential as a Promising Liquid Biopsy Biomarker.

ABSTRACT: Drug resistance is a major challenge in cancer therapy, and the expression of efflux pumps such as P-glycoprotein (P-gp, ABCB1) often correlates with poor prognosis in various tumors, including glioblastoma (GB). Considering that different roles for these proteins have been established in the biology of various tumors, this study aimed to investigate the functions of P-gp in GB-derived cells by evaluating its survival, migratory, and apoptosis-regulating capabilities, as well as its potential as a liquid biopsy biomarker. P-gp expression was diminished via siRNA to determine its exact role in GB biology. The P-gp mRNA levels were evaluated by using quantitative real-time RT-PCR. With respect to liquid biopsy, circulating cell-free RNA was extracted from plasma belonging to patients diagnos
