The results indicated that YTHDF2 knockdown accelerated the growth rates of AGS, SGC7901, as well as BGC823 cells (Fig. 2B, 2C).​ To further detect the impact of YTHDF2 knockdown on cell migration, transwell chamber assays were carried out in the above stable cell lines, and we found that suppression of YTHDF2 expression augmented the migratory potential of GC cells (Fig. 2D). The gene discussed is YTHDF2; the disease is gastric cancer.
