在癌症的背景下,E-钙粘蛋白传统上被归类为肿瘤抑制因子,因为其在形成适当的细胞间连接中起重要作用,并且其在上皮肿瘤进展中的上皮-间充质转化(EMT)过程中下调。在一小部分上皮癌中,已经描述了E-钙粘蛋白基因(CDH 1)的生殖系或体细胞突变或表观遗传机制的下调。然而,最近的证据也指出了E-钙粘蛋白在肿瘤进展的几个方面的促进作用。其中包括保存炎性乳腺癌微栓子中的E-钙粘蛋白表达(或增加),卵巢癌中可能的“间充质向上皮转化”(MET),一些上皮癌中的集体细胞侵袭,最近E-钙粘蛋白表达与更具侵袭性的脑肿瘤亚群的相关性,以及E-cadherin参与细胞质和/或细胞核中特定信号网络的有趣可能性。在这篇综述中,我们解决了一个鲜为人知的,积极的作用,E-钙粘蛋白在癌症。
In the context of cancer, E-cadherin has traditionally been categorized as a tumor suppressor, given its essential role in the formation of proper intercellular junctions, and its downregulation in the process of epithelial-mesenchymal transition (EMT) in epithelial tumor progression. Germline or somatic mutations in the E-cadherin gene (CDH1) or downregulation by epigenetic mechanisms have been described in a small subset of epithelial cancers. However, recent evidence also points toward a promoting role of E-cadherin in several aspects of tumor progression. This includes preserved (or increased) E-cadherin expression in microemboli of inflammatory breast carcinoma, a possible “mesenchymal to epithelial transition” (MET) in ovarian carcinoma, collective cell invasion in some epithelial cancers, a recent association of E-cadherin expression with a more aggressive brain tumor subset, as well as the intriguing possibility of E-cadherin involvement in specific signaling networks in the cytoplasm and/or nucleus. In this review we address a lesser-known, positive role for E-cadherin in cancer.
