Analysis of basal protein levels in the five NSCLC cell lines also failed to reveal any clear correlations between OTX015 sensitivity and basal protein levels of BRD2, BRD3, BRD4, MYC, MYCN, cyclin D1, P21, BCL2 or p-Tyr705STAT3 (Supplementary Figure S1B). This evidence concerns the gene BRD4 and non-small cell lung carcinoma.
