WNT10A是WNT基因家族的重要成员,该家族编码一类分泌型糖蛋白,通过调控WNT信号通路参与胚胎发育、细胞增殖和分化等关键生物学过程。WNT10A编码的蛋白质作为配体与细胞膜上的Frizzled受体结合,激活经典的β-catenin依赖通路或非经典的平面细胞极性(PCP)通路,主要作用于皮肤、牙齿、毛发和骨骼等组织的形态发生。其突变可导致多种遗传病,如少汗型外胚层发育不良(EDA),表现为牙齿缺失、汗腺发育异常和毛发稀疏。WNT10A功能丧失突变还会引起牙本质发育不全和某些骨骼畸形。该基因过表达可能激活异常细胞增殖,与某些肿瘤如结直肠癌的发生相关;而表达降低则可能导致组织再生障碍或发育缺陷。WNT家族共有的特点是均含23-24个保守半胱氨酸残基,形成特定三维结构以结合受体。WNT10A与家族其他成员(如WNT3、WNT5A)功能部分重叠,但在牙齿发育中具有不可替代的作用。目前研究发现WNT10A单核苷酸多态性(SNP)与肥胖和2型糖尿病易感性相关,其机制可能涉及脂肪细胞分化调控。术语说明:WNT是"Wingless/Integrated"的缩写,源于果蝇翅发育基因与小鼠乳腺肿瘤基因的融合发现;外胚层发育不良(ectodermal dysplasia)指源自外胚层的组织(如皮肤附件)发育异常;平面细胞极性(planar cell polarity, PCP)描述细胞在组织平面内的定向排列特性。
The WNT gene family consists of structurally related genes which encode secreted signaling proteins. These proteins have been implicated in oncogenesis and in several developmental processes, including regulation of cell fate and patterning during embryogenesis. This gene is a member of the WNT gene family. It is strongly expressed in the cell lines of promyelocytic leukemia and Burkitt's lymphoma. In addition, it and another family member, the WNT6 gene, are strongly coexpressed in colorectal cancer cell lines. The gene overexpression may play key roles in carcinogenesis through activation of the WNT-beta-catenin-TCF signaling pathway. This gene and the WNT6 gene are clustered in the chromosome 2q35 region.

Wnt信号基因家族由结构相关基因,其编码分泌信号蛋白。这些蛋白质有牵连肿瘤发生并在几个发育过程,包括胚胎发育过程中细胞命运和图案化的调节。此基因是WNT基因家族的一个成员。它在早幼粒细胞白血病和伯基特淋巴瘤的细胞系中强烈表达。此外,它和其他家庭成员,WNT6基因,强烈结肠癌细胞系中共表达。基因表达可能癌变通过WNT-β-连环蛋白的TCF信号转导通路的活化中起关键作用。此基因和WNT6基因都聚集在染色体2q35区域。 [由RefSeq的,2008年7月提供]
