Contrary to our conclusion, Pu et al. reported that miRNA-34a-5p mimic-restoration sustained the multi-chemoresistance of MDR- SJSA-1 osteosarcoma cell lines via direct repression of angiotensin II type 1 receptor (AGTR1) [49], Delta-like ligand 1 (DLL1), the ligand of the Notch pathway, [50], and receptor tyrosine kinase CD117 [51]. Here, DLL1 is linked to osteosarcoma.
