Figure 1. Relative expression levels of RNA methylation-related genes in both normal and PA embryos. The expression levels of METTL3 (A), METTL14 (B), FTO (C), and ALKBH5 (D) were analyzed by qRT-PCR. The data are represented as means ± S.E.M. (n = 3). * p<0.05, ** p<0.01, *** p<0.005 indicate the respective statistically significant differences.
