Abstract

BACKGROUND: Aberrant proliferation and migration of vascular smooth muscle cells (VSMCs) play an important role in the pathogenesis of cardiovascular diseases including coronary heart disease (CHD). MicroRNAs has reported play critical roles in VSMCs function. The present study was to investigate the effects of microRNA‑23 (miR-23) on VSMCs and uncover its potential mechanism. METHODS: Cell viability was detected by CCK-8 assay. Cell apoptosis was measured by flow cytometry. Dual luciferase reporter assay was conducted to verify whether BCL2L11 is a target gene of miR-23. The protein levels of BCL2L11 and caspase-3 were detect by quantitative real time PCR and western blot. RESULTS: Our results showed that the expression of miR-23 was upregulated in peripheral blood of CHD patients compared with controls. Overexpression of miR-23 promoted VSMCs proliferation and inhibited VSMCs apoptosis. Downregulation of miR-23 suppressed VSMCs proliferation and promoted VSMCs apoptosis. In addition, we identified BCL2L11 was a direct gene of miR-23. Overexpression of miR-23 decreased the levels of BCL2L11 and caspase-3, and downregulate of miR-23 increased the levels of BCL2L11and caspase-3 in VSMCs. CONCLUSION: Our findings suggest that miR-23 plays a crucial role in controlling VSMCs proliferation and apoptosis by targeting BCL2L11.

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • miR-23 is upregulated in the peripheral blood of patients with coronary heart disease.

    “Similarly, researchers have observed that miR-23 is also upregulated in the peripheral blood of patients with coronary heart disease (CHD).”
  • Overexpression of miR-23 can promote the proliferation of vascular smooth muscle cells and inhibit apoptosis through the target BCL2L11.

    “Overexpression of miR-23 can promote the proliferation of VSMCs and inhibit apoptosis through another target BCL2L11 [49].”

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.
