PTGES3 proteolysis using the liposomal peptide-PROTAC approach.

ABSTRACT:

Background

Hepatocellular carcinoma (HCC) is the leading cause of cancer-related deaths worldwide, and the lack of effective biomarkers for early detection leads to poor therapeutic outcomes. Prostaglandin E Synthase 3 (PTGES3) is a putative prognostic marker in many solid tumors; however, its expression and biological functions in HCC have not been determined. The proteolysis-targeting chimera (PROTAC) is an established technology for targeted protein degradation. Compared to the small-molecule PROTAC, the peptide PROTAC (p-PROTAC) utilizes peptides bound to target proteins to mediate the ubiquitination and degradation of undruggable proteins. This study aimed to use the PROTAC technology to develop a PTGES3 degrader liposome complex containing a PTGES3-binding peptide and the E3
