Genes identified as being mutated in Wilms' tumour include TP53, a classic tumour suppressor gene (TSG); CTNNB1 (encoding β-catenin), a classic oncogene; WTX, which accumulating data indicate is a TSG; and WT1, which is inactivated in some Wilms' tumours, similar to a TSG. However, WT1 does not always conform to the TSG label, and some data indicate that WT1 enhances cell survival and proliferation, like an oncogene. Is WT1 a chameleon, functioning as either a TSG or an oncogene, depending on cellular context? Are these labels even appropriate for describing and understanding the function of WT1?
在维尔姆斯瘤中鉴定出的突变基因包括 TP53,一个经典的肿瘤抑制基因(TSG);CTNNB1(编码β-连环蛋白),一个经典的癌基因;WTX,越来越多的数据表明它是一个 TSG;以及 WT1,它在一些维尔姆斯瘤中失活,类似于 TSG。然而,WT1 并不总是符合 TSG 标签,有些数据表明 WT1 增强细胞存活和增殖,类似于癌基因。WT1 是变色龙吗,根据细胞环境,它可以作为 TSG 或癌基因发挥作用?这些标签是否甚至适合描述和理解 WT1 的功能?
