We enriched a total of one hundred and sixty-seven mRNAs related to HAT1 and PD-L1, among which nine key mRNAs (K-mRNAs, for details, see the description in the “Methods” section) were significantly correlated (using a simple linear correlation with a p value less than 0.05) with the natural log half-maximal inhibitory concentration (LN-IC50) of JQ-1 in the melanoma cell lines. Here, CD274 is linked to melanoma.
