TRPM1 and melanoma: We looked for a positive correlation in the expression levels of TRPM1 and TRPM3 in the melanoma cases profiled by microarray in ref [25] (n=45), ref [26] (n=56), ref [27] (n=28), ref [28] (n=214) and at www.cbioportal.org, however no correlation was discovered (Supplementary Figure 10a-10e, left panels and Supplementary Table 6).
