BIMODAL MELANOMA PATHWAYS
Epidemiological data support that early-onset melanoma may represent gene-intermittent sun exposure interaction while late-onset melanoma may reflect chronic exposure sun damage.

RETINOIC ACID AND MELANOMA
In an in vitro model, retinoic acid receptor gamma (RARg) inhibits melanoma invasiveness by inducing expression of carbohydrate sulfotransferase-10 (CHST10).

C10, A TLR3 INHIBITOR
In a xenograft model, phenylmethimazole (C10) decreases toll like receptor-3 (TLR3) and non-canonical WNT5a signaling, and shows anti-melanoma activity.
