We use Kaplan-Meier - Plotter database analysis (http://www.kmplot.com/analysis/), the result shows: High expression of ALKBH5, HNRNPA2B1, IGF2BP1, KIAA1429, YTHDC1, METTL3, YTHDF1 and YTHDF2 was associated with shorter progression-free survival (PFS) in ovarian cancer patients. This evidence concerns the gene YTHDC1 and ovarian cancer.
