ABCC1 and lung adenocarcinoma: Notably, miR-134 itself has been reported to sensitize cisplatin-resistant human lung adenocarcinoma cells to cisplatin, vincristine, and 5-fluorouracil by targeting the 3′-UTR of Forkhead box M1 (FOXM1) mRNA, leading to the downregulation of multidrug resistance-associated protein 1 (MRP1) protein levels [98], and has also been reported to sensitize AML cells to cytarabine by targeting the 3′UTR of MAPK signaling-interacting kinase 1 (MNK1) and 2 (MNK2) mRNAs [99].
