JUN and cancer: With the aid of systems biology, a rank-based radiosensitivity index (RSI) derived from 10 genes (AR, c-JUN [JUN], STAT1, PKC [PRKCB], Rel A [RELA], cABL [ABL1], SUMO1, CDK1, HDAC1, and IRF1), has been generated to predict the survival fraction at 2 Gy (SF2) across 48 cancer cell lines2.
