Moreover, the data generated from the Cancer Cell Line Encyclopedia (CCLE) and Genomics of Drug Sensitivity in Cancer (GDSC)21,22 showed that the ELP5 mRNA expression across over 500 cancer cell lines was negatively correlated with the 50% inhibitory concentration (IC50) of gemcitabine (Supplementary Fig. 2a), suggesting that ELP5 was associated with gemcitabine resistance. This evidence concerns the gene ELP5 and cancer.
