Additionally, Y Song et al. established a nomogram based on the expression level of seven m6A-related lncRNAs (AC008669.1, AC010336.1, AC097376.3, AC130710.1, ACAP2-IT1, AL138820.1 and CACNA1G-AS1) to predict survival rate of patients with ovarian cancer, revealing that m6A-related lncRNAs may act an important role in ovarian cancer treatment [151]. This evidence concerns the gene PTGDR and ovarian cancer.
