Research progress of carboxyl peptide fragment of clostridium perfringens enterotoxin in the treatment of tumors / 肿瘤研究与临床

There are approximately 85 ％ of malignant tumors derived from epithelial cells,and a therapeutic method of epithelial cells has become the focus of cancer treatment.Claudin-3 and Claudin-4 as important components of the tight junction structure are abundantly expressed in malignant tumors,and the clostridium perfringens enterotoxin (CPE) as Claudin-3 and Claudin-4 specific binding ligand has important significances in the treatment of tumors.However,because of the large intestinal toxicity,clinical application of CPE has been limited greatly.Carboxyl peptide fragment of CPE (C-CPE) is a specific binding domain of CPE,which has specificity without intestinal toxicity.This review will present some advances of C-CPE in cancer therapy.

Research progress of relationship between claudin protein and pancreatic neoplasms / 国际外科学杂志

claudin protein is the major component of tight junctions complex between cells,which plays an important role in cells junction and adhesion. Its specific expression in different tissues directly affects the biological behavior of tumor cells. In pancreatic tumors, the claudin's expression provides an important refer-ence for the diagnosis and treatment of tumors. In addition, claudin are involved in the proliferation and ap-optosis of tumor cells. In the treatment of tumors, claudin-mediated targeting therapy has great prospects forthe same.
