In contrast, four m6A regulators including insulin like growth factor binding protein 1 (IGFBP1), insulin like growth factor binding protein 2 (IGFBP2), insulin like growth factor 2 mRNA binding protein 1 (IGF2BP1), and insulin like growth factor binding protein 1 (IGFBP1), alkB homolog 5 (ALKBH5), and one m1A regulators (tRNA methyltransferase 61A (TRMT61A)), exhibited higher expression levels in Con compared to PTSD. This evidence concerns the gene IGFBP2 and post-traumatic stress disorder.
