Jin X, Yang GY (2023) Pathophysiological roles and applications of glycosphingolipids in the diagnosis and treatment of cancer diseases. Prog Lipid Res 101241. doi: 10.1016/j.plipres.2023.101241 PMID: 37524133
Objective: The authors review the tumor-related biological functions of GSLs and recent progress in using GSLs and related enzymes to diagnose and treat tumor diseases.
Summary: Glycosphingolipids (GSLs) are glycolipids present on the surface of living cell membranes. Specific GSLs and related enzymes are abnormally expressed in many cancer diseases and affect the malignant characteristics of tumors. The regulatory roles of GSLs in signaling pathways suggest that they are involved in tumor pathogenesis. GSLs have therefore been widely studied as diagnostic markers of cancer diseases and important targets of immunotherapy.
Usage: The stage-specific embryonic antigen-4 (SSEA4) mAb, MC-813-70, was mixed with Mab-ZAP at a molar ratio of approximately 3:1 with the complex used at nanomolar concentrations on MDA-MB-231 cells, a triple negative breast cancer cell known to express SSEA-4. The conjugate was able to reduce tumor viability in vitro.
