The 12-LOX/12-HETE/GPR31 metabolic pathway promotes tumor-associated macrophage M2 polarization mediated pancreatic cancer development.

ABSTRACT:

Background

The 12-lipoxygenase (12-LOX)/12-hydroxyeicosatetraenoic acid (12-HETE) pathway is associated with various tumors. M2 macrophages in the tumor microenvironment promote tumorigenesis and progression. However, the role of the 12-LOX/12-HETE/G protein-coupled receptor 31 (GPR31) metabolic pathway and its relationship with M2 macrophages remains unclear in pancreatic cancer (PC).

Methods

The expression levels of 12-LOX, GPR31, and 12-HETE were detected in PC and mouse PC models using western blot and enzyme-linked immunosorbent assays (ELISA). In vivo and in vitro experiments were conducted using the 12-LOX inhibitor ML355 to investigate the role of the 12-LOX/12-HETE/GPR31 metabolic pathway in M2 macrophage polarization and tumor progression through flow
