To further confirm the TAZ expression results in GBM, a western blot assay was used to measure the GBM cell lines, tissues derived from normal tissue, tumor center and peritumor, the result revealed that TAZ was commonly expressed in GBM cell lines (U118, U251 LN229, A172 and U87) and highly expressed in tumor center compared to normal tissue. The gene discussed is WWTR1; the disease is glioblastoma.
