HNRNPA2B1 and acute respiratory distress syndrome: Expression levels of m6A regulators across all cell types in septic ARDS were examined, and t-SNE plots of these m6A regulators are shown in Fig. 2B. Notably, WTAP, HNRNPA2B1, and HNRNPC exhibited higher expression across all cell types, whereas other m6A regulators showed minimal or no significant expression (Fig. 2C).
