Abstract

A mutational analysis of the matrix metalloproteinase (MMP) gene family in human melanoma identified somatic mutations in 23% of melanomas. Five mutations in one of the most commonly mutated genes, MMP8, reduced MMP enzyme activity. Expression of wild-type but not mutant MMP8 in human melanoma cells inhibited growth on soft agar in vitro and tumor formation in vivo, suggesting that wild-type MMP-8 has the ability to inhibit melanoma progression.

摘要

一项对人类黑色素瘤中基质金属蛋白酶(MMP)基因家族的突变分析发现,23%的黑色素瘤存在体细胞突变。在最常发生突变的基因之一MMP8中,有五个突变降低了MMP酶的活性。在人类黑色素瘤细胞中表达野生型而非突变型MMP8可抑制体外软琼脂上的生长和体内肿瘤形成,这表明野生型MMP-8具有抑制黑色素瘤进展的能力。
