FSTL1 promotes M2 polarization of macrophages via the DIP2A–Smad2/3 Axis in gastric cancer
Follistatin-like protein 1 (FSTL1) is aberrantly overexpressed in gastric cancer (GC) and modulates immune cell infiltration in the tumor microenvironment. However, the molecular mechanism underlying its regulation of macrophage polarization remains incompletely defined. In this study, we analyzed the expr...
