钙黏素和整合素在卵巢上皮性癌中的研究进展

Research progress on cadherins and integrins in ovarian epithelial cancer

卵巢上皮性癌(EOC)是妇科癌症中最致命的恶性肿瘤。在过去的30年间,虽然诊断和治疗水平取得了进展,但是卵巢上皮性癌的发病率和死亡率却保持不变。卵巢上皮性癌腹膜转移癌晚期发病于附着的小簇癌细胞,这些癌细胞从初始部位脱落并经由腹水携带附着于腹部腹膜或网膜。这种行为表明细胞-细胞或细胞-基质黏附机制调节卵巢上皮性癌的生长和增殖。复杂的下游信号可能受黏附分子和共表达激活的信号蛋白之间的功能性串扰所影响,导致卵巢上皮性癌细胞的增殖/存活和迁移/侵袭。本文旨在阐述细胞与细胞机制的影响,该过程由钙黏素和细胞-细胞外基质黏附,由整合素对膜受体和细胞质蛋白质介导的信号级联放大,这些在卵巢上皮性癌细胞的增殖、迁移和侵袭中起着一定的作用。

Epithelial ovarian cancer（ EOC） is the most deadly malignant tumor in gynecological cancer.In the past 30 years,although the levels of diagnosis and treatment have made progress,the incidence of EOC and mortality are constant. Over the past few decades,a comprehensive study for molecular mechanisms of EOC progression has been conducted in order to develop new and more effective treatments. Advanced peritoneal metastases occur in the attached small clusters of cancer cells,which shed from the initial site and carried it through the ascites to the abdominal peritoneum or omentum. This behavior suggests that cell-cell or cell-matrix adhesion mechanisms regulate the growth and dissemination of EOC. Complex downstream signaling may be affected by functional crosstalk between adhesion molecules and,co-expressed and activated signaling proteins,which affect the proliferation/survival and migration/invasion of EOC cells. The aim of this review is to define effects of cell and cellular mechanisms,which are adhered by the cadherin and the cell-extracellular matrix,and cascaded by integrin-mediated membrane receptor and cytoplasmic protein-mediated cascade amplification,which is expressed in proliferation,migration and invasion of epithelial ovarian cancer cells.
