Assessment of gene expression levels of proopiomelanocortin (POMC) and melanocortin-1 receptor (MC1R) in vitiligo.

Proopiomelanocortin (POMC) and melanocortin 1 receptor (MC1R) are regulators of melanogenesis and pigmentation. Our objective was to estimate their levels, searching for a possible role of the melanocortin system in vitiligo. This study included 40 vitiligo patients and 40 controls.
