RNA seq from GBM cell lines and primary cultures after irradiation

Glioblastoma is the most common, aggressive tumor of CNS, with a 5-year overall survival rate of 5%. The treatment is challenging due to its location and the inevitable recurrence in 80% of the cases. To understand the cause behind this recurrence, we established an in vitro radiation survival model that mimics clinical scenarios. GBM Parent (P) cells, after being given a lethal dose of radiation, undergo tremendous cell death but leave behind a small residual surviving population that shows senescence phenotype. These residual (RS) cells eventually reverse from senescence (End of senescence) and give rise to aggressive relapse (R). To find molecular players behind this reversal of senescence, we carried out RNA sequencing of GBM cell lines U87MG and SF268 at mentioned stages of senescence post-radiation treatment.
