Liu performed immunohistochemical staining in 20 matched BC and adjacent normal tissues with a BC tissue microarray (TMA) and found the upregulation of WTAP (p = 0.002), KIAA1429 (p < 0.001), and RBM15 (p = 0.012) but no significant changes in METTL3, METTL14, METTL16, or RBM15B in BC specimens (Liu et al., 2019), which was different from mRNA expression. This evidence concerns the gene VIRMA and breast cancer.
