克劳丁(Claudins)是紧密连接蛋白家族,可调节细胞旁通透性和细胞极性,在人类良恶性组织中具有不同的表达模式。到目前为止,已鉴定出大约27种克劳丁家族成员,它们具有不同的细胞和组织特异性表达。克劳丁 -3、-4和 -7是卵巢癌中表达差异最显著的克劳丁蛋白。虽然它们在卵巢肿瘤中的确切作用仍在阐明之中,但这些蛋白被认为对卵巢癌细胞的侵袭/扩散以及对化疗的耐药性至关重要。克劳丁 -3和克劳丁 -4是产气荚膜梭菌肠毒素(CPE)的天然受体,CPE是一种强效的溶细胞毒素。因此,这些表面蛋白可能是使用基于CPE的诊疗剂检测和治疗对化疗耐药的卵巢癌以及其他过度表达克劳丁 -3和 -4的侵袭性实体瘤的有吸引力的靶点。
Claudins are a family of tight junction proteins regulating paracellular permeability and cell polarity with different patterns of expression in benign and malignant human tissues. There are approximately 27 members of the claudin family identified to date with varying cell and tissue-specific expression. Claudins-3, -4 and -7 represent the most highly differentially expressed claudins in ovarian cancer. While their exact role in ovarian tumors is still being elucidated, these proteins are thought to be critical for ovarian cancer cell invasion/dissemination and resistance to chemotherapy. Claudin-3 and claudin-4 are the natural receptors for the Clostridium perfringens enterotoxin (CPE), a potent cytolytic toxin. These surface proteins may therefore represent attractive targets for the detection and treatment of chemotherapy-resistant ovarian cancer and other aggressive solid tumors overexpressing claudin-3 and -4 using CPE-based theranostic agents.
