Figure Lengend Snippet: Galectin-1 promotes MMT in HPMCs through the TGF-β/Smad signaling pathway (A–D) WB analysis of TGF-β1 and p -Smad2/3 in HMrSV5 cells treated with CM from SGC-7901 cells (A and B) and HGC-27 cells (C and D) with different LGALS1 expression levels ( n = 3). (E–H) WB confirmed E-cadherin and vimentin expression in HMrSV5 cells treated with CM from SGC-7901 cells (E and F) and HGC-27 cells (G and H) with different LGALS1 expression levels or CM-OE- LGALS1 supplemented with ITD1. Data are represented as mean ± SD. ∗∗ p < 0.01, NS, p > 0.05.
