It is mainly mediated by the poreforming protein Gasdermin (GSDM) family. Activated caspases cleave Gasdermin family members to release N-terminal domains that punch holes in the cell membrane, leading to cell swelling, rupture and death. Gasdermin B (GSDMB) belongs to the Gasdermin (GSDM) family and has pro-or anti-tumor effects. Studies on tumor cells have found that GSDMB is highly expressed in breast cancer, gastric cancer, liver cancer, cervical cancer and colon cancer cells. Therefore, scholars believe that GSDMB may be involved in cancer progression and metastasis as an oncogene. This article reviews the role of GSDMB in various malignant tumors, in order to provide new ideas for the clinical diagnosis, treatment and prognosis of tumors.展开更多
