HNRNPA1 and gastric cancer: In addition, Zhang et al. discovered that exosome lncFERO derived from gastric cancer cells enhances the stearoyl-coenzyme A desaturase-1 protein expression while recruiting heterogeneous nuclear ribonucleoprotein A1 (hnRNPA1), leading to dysregulated PUFA levels and suppressed ferroptosis activity, thereby reducing chemosensitivity of cancer stem cells (CSCs) [81].
