Abstract

In contrast with sun exposure–induced melanoma, rarer melanocytic tumors and neoplasms with low mutational burden present opportunities to study isolated signaling mechanisms. These include uveal melanoma and blue nevi, which are often driven by mutations within the G protein–coupled signaling cascade downstream of cysteinyl leukotriene receptor 2. Here, we review how the same mutations within this pathway drive the growth of melanocytes in one tissue but can inhibit the growth of those in another, exemplifying the role of the tissue environment in the delicate balance between uncontrolled cell growth and senescence.

GPCR CysLTR1/2 介导的信号通路在黑色素细胞增殖和衰老中的作用

与阳光照射诱导的黑色素瘤相比，较罕见的黑色素细胞肿瘤和突变负荷较低的肿瘤为研究孤立的信号转导机制提供了机会。这些肿瘤包括葡萄膜黑色素瘤和蓝痣，它们通常是由半胱氨酰白三烯受体2下游的G蛋白偶联信号级联中的突变驱动的。在这里，我们将回顾这一通路中的相同突变是如何在一个组织中驱动黑色素细胞生长，但在另一个组织中却能抑制黑色素细胞生长的，从而说明组织环境在细胞失控生长与衰老之间的微妙平衡中所起的作用。
