Abstract

SUMMARY: The aim of the present study was to determine the role of myocardial microvascular endothelial cells (MMVEC) in impaired angiogenesis of type 2 diabetic Goto‐Kakizaki (GK) rats. A microRNA (miRNA) microarray was used to assess miRNA expression in MMVEC from GK and Wistar rats. Upregulation of miRNA‐320 was observed in MMVEC from GK rats using real‐time reverse transcription–polymerase chain reaction (RT‐PCR). So far, nine miRNAs have been reported to target angiogenic factors and/or receptors, including kinase insert domain containing receptor (Flk‐1), insulin‐like growth factor 1 (IGF‐1) and insulin‐like growth factor 1 receptor (IGF‐1R). The predicted genes targeted by miR‐320 include Flk‐1, IGF‐1 and IGF‐1R. Western blot analysis and RT‐PCR were used to analyse the protein and mRNA expression, respectively, of the putative genes IGF‐1 and IGF‐1R. The expression of IGF‐1 and IGF‐1R proteins decreased significantly in diabetic MMVEC. However, the expression of IGF‐1 mRNA increased rather than decreased. The mRNA expression of IGF‐1R did not differ significantly between diabetic and control MMVEC. Transfection of an miR‐320 inhibitor into MMVEC from GK rats confirmed that miR‐320 impaired angiogenesis. The proliferation and migration of diabetic MMVEC improved after transfection of the miR‐320 inhibitor. In addition, the miR‐320 inhibitor significantly increased the expression of IGF‐1 protein, but had no effect on the expression of IGF‐1R. Eleven miRNAs were upregulated in MMVEC from GK rats compared with those in Wistar rats: let‐7e, miR‐129, miR‐291‐5p, miR‐320, miR‐327, mir‐333, miR‐363–5p, miR‐370, miR‐494, miR‐503 and miR‐664. The results indicate that upregulation of miR‐320 in MMVEC from GK rats may be responsible for the inconsistency between the expression of IGF‐1 protein and mRNA and therefore related to impaired angiogenesis in diabetes. Transfection of an miR‐320 inhibitor may be a therapeutic approach for the treatment of impaired angiogenesis in diabetes.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
