In contrast, in melanoma, only 34, 73, 6, 137 and 146 genes’ expression correlated with the expression levels of TAAR1, TAAR2, TAAR5, TAAR6, and TAAR8 (r > 0.7, p < 0.05), considering that TAAR1, TAAR2, and TAAR5 expression levels in melanoma were below the cut-off value 0.5 TPM. Here, TAAR2 is linked to melanoma.
