[The effect of alpha-melanocyte-stimulating hormone and its analog on the growth of human melanoma cell lines with different phenotypes].
Investigation of physiological effects of alpha-MSH and its analog (NLe4, D-Phe7)-alpha-MSH on human melanoma cells with different phenotypes has shown that these peptides have a growth-modulating activity. The effect of inhibition or activation of the growth of melanoma cells depended on their phenotypes. (NLe4, D-Phe7)-alpha-MSH activated 1.5-2.5-fold the growth of amelanotic BRO cells at concentrations of 10(-6)-10(-12) M, but inhibited the growth of melanin-producing MS cells under the same conditions not affecting the growth of human lung fibroblasts.
