PXDNL and neoplasm: In m6A-TSHub, a total of 184,554 and 499,369 m6A sites derived from 23 normal human tissues and 25 matched tumor samples were collected (m6A-TSDB), from which some potential patterns for the tissue-specific m6A modification sites were revealed (e.g., heart-enriched genes RYR2 and PXDNL; Figure S2).
