A. Ontogeny of m6A abundance throughout brain development. Total RNA was isolated from mouse brain at embryonic day 18 (E18), postnatal day 0 (P0), postnatal day 14 (P14), and adulthood, then subjected to immunoblot analysis to detect m6A-containing transcripts. Ethidium bromide staining of 28S rRNA bands is shown as a loading control.
B. FTO demethylates a wide range of cellular transcripts. FTO was expressed in HEK293T cells for 48h, and cellular RNA was subjected to immunoblot analysis to detect m6A.
