SLC9A1 and breast cancer: Jia et al. have revealed that adipose mesenchymal stem cell (ADMSC)-derived exosomes, containing miR-1236, can decrease BC cell resistance against DDP by inhibiting the solute carrier family 9 member A1 (SLC9A1) Na+/H+ anti-porter and inactivating the Wnt/β-catenin signaling pathway (Jia et al., 2020).
