FOXS1 and gastric cancer: In addition, Cao Y. et al. reported that miR-125a-5p expression was lower in human gastric cancer cell lines (SGC7901, HGC27 and BGC823) than in the normal gastric mucosa cell line GES1, with a similar pattern in 82 pairs of cancer tissues and matched normal tissues, as evidenced by RT-PCR analysis22,42, while FOXS1 was highly expressed in the above gastric cancer cell lines and gastric cancer tissues, revealing that the endogenous FOXS1 and miR-125a-5p levels were inversely correlated.
