We also determined the methylation sites by performing single-base elongation- and ligation-based qPCR amplification (SELECT) analysis for the detection of single m6A locus at single-base resolution63, and found that m6A levels of A3656 in the 3′ UTR of Nox2 were significantly increased upon H37Rv(ΔEsxB) infection, compared to those infected with H37Rv, but this increment was not observed in mMettl14−/− macrophages (Fig. 3g). The gene discussed is CYBB; the disease is infection.
