Overexpression of miR-19a and miR-20a in iPS-MSCs preserves renal function of chronic kidney disease with acute ischaemia-reperfusion injury in rat.

ABSTRACT: This study tested the hypothesis that therapy with double overexpression of miR-19a-3p and miR-20a-5p (miR^DOE ) to human inducible pluripotent stem cell-derived mesenchymal stem cells (iPS-MSCs) was superior to iPS-MSCs alone for preserving renal function in rat with pre-existing chronic kidney disease (CKD), followed by ischaemia-reperfusion (IR) injury. In vitro study demonstrated that the protein expressions of oxidative stress (NOX-1/NOX-2/NOX4/oxidized protein/p22phox), inflammatory downstream signalling (TLR2&4/MyD88/TRAF6/IKK-ß/p-NFκB/IL-1ß/IL-6/MMP-9) and cell apoptosis/death signalling (cleaved caspase-3/mitochondrial Bax/p-ERKs/p-JNK/p-p38) at time-points of 24-hour/48-hour cell cultures were significantly increased in p-Cresol-treated NRK-52E cells than in the control
