Fig. 5

A Levels of TGF-β in ascites of non-PM group (n = 12) and PM group (n = 18) GC patients; B Pearson analysis of the correlation between MPO-DNA in ascites of PM group (n = 18) GC patients and TGF-β levels; C Detection of LIF mRNA levels by RT-qPCR and protein expression of LIF, Smad2/3 by Western Blot; D ChIP-qPCR to detect potential binding sites of Smad2/3 in the LIF promoter region; E Dual-Luciferase reporter assay to investigate the transcriptional regulation of LIF by Smad2/3; F ELISA to measure the levels of LIF in GC cell culture medium. * Indicates that P < 0.05 and cell experiments are repeated at least three times.
