CCL5 and melanoma: This is consistent with the TCGA data of global PRELP (log2 5.7 to 13) (Additional file 1: Fig. S6A) and PRELPhigh (log2 > 10.6) (Additional file 1: Fig. S6B) melanoma with a higher OS (global PRELP; p = 0.00006; log-rank test = 17.72; PRELPhigh; p = 0.002; log-rank test = 9.472) upon high CCL5 expression.
