Renal AAV2-Mediated Overexpression of Long Non-Coding RNA H19 Attenuates Ischemic Acute Kidney Injury Through Sponging of microRNA-30a-5p
Renal ischemia-reperfusion (I/R) injury is a major cause of AKI. Noncoding RNAs are intricately involved in the pathophysiology of this form of AKI. Transcription of hypoxia-induced, long noncoding RNA , which shows high embryonic expression and is silenced in adults, is upregulated in renal I/R inj...

Summary: | Renal ischemia-reperfusion (I/R) injury is a major cause of AKI. Noncoding RNAs are intricately involved in the pathophysiology of this form of AKI. Transcription of hypoxia-induced, long noncoding RNA
, which shows high embryonic expression and is silenced in adults, is upregulated in renal I/R injury.
Lentivirus-mediated overexpression, as well as antisense oligonucleotide-based silencing, modulated

analyses used constitutive
knockout mice. In addition, renal vein injection of adeno-associated virus 2 (AAV2) carrying
caused overexpression in the kidney. Expression of
in kidney transplant patients with I/R injury was investigated.
is upregulated in kidney biopsies of patients with AKI, in murine ischemic kidney tissue, and in cultured and
sorted hypoxic endothelial cells (ECs) and tubular epithelial cells (TECs). Transcription factors hypoxia-inducible factor 1-
, LHX8, and SPI1 activate
in ECs and TECs.

, transient AAV2-mediated
overexpression significantly improved kidney function, reduced apoptosis, and reduced inflammation, as well as preserving capillary density and tubular epithelial integrity. Sponging of miR-30a-5p mediated the effects, which, in turn, led to target regulation of Dll4, ATG5, and Snai1.
overexpression confers protection against renal injury by stimulating proangiogenic signaling.
overexpression may be a promising future therapeutic option in the treatment of patients with ischemic AKI. |
