Abstract

Variation on chromosome 9p21 is associated with risk of coronary artery disease (CAD). This genomic region contains the CDKN2A and CDKN2B genes which encode the cell cycle regulators p16(INK4a), p14(ARF) and p15(INK4b) and the ANRIL gene which encodes a non-coding RNA. Vascular smooth muscle cell (VSMC) proliferation plays an important role in the pathogenesis of atherosclerosis which causes CAD. We ascertained whether 9p21 genotype had an influence on CDKN2A/CDKN2B/ANRIL expression levels in VSMCs, VSMC proliferation and VSMC content in atherosclerotic plaques. Immunohistochemical examination showed that VSMCs in atherosclerotic lesions expressed p16(INK4a), p14(ARF) and p15(INK4b). Analyses of primary cultures of VSMCs showed that the 9p21 risk genotype was associated with reduced expression of p16(INK4a), p15(INK4b) and ANRIL (P = 1.2 × 10(-5), 1.4 × 10(-2) and 3.1 × 10(-9)) and with increased VSMC proliferation (P = 1.6 × 10(-2)). Immunohistochemical analyses of atherosclerotic plaques revealed an association of the risk genotype with reduced p15(INK4b) levels in VSMCs (P = 3.7 × 10(-2)) and higher VSMC content (P = 5.6 × 10(-4)) in plaques. The results of this study indicate that the 9p21 variation has an impact on CDKN2A and CDKN2B expression in VSMCs and influences VMSC proliferation, which likely represents an important mechanism for the association between this genetic locus and susceptibility to CAD.

  • Chromosome 9p21 encodes the long non-coding RNA ANRIL, which regulates cell proliferation, adhesion, and apoptosis, central mechanisms of atherogenesis and endometriosis.

    “Chr9p21 encodes the long non-coding RNA(ncRNA) ANRIL, which has been demonstrated to regulate cell proliferation, adhesion and apoptosis,(43, 44) - central mechanisms of atherogenesis (13, 43) and endometriosis. (2, 3)”

    From Endometriosis and Risk of Coronary Heart Disease (2016) · cites this paper as [44]

    The Introduction identifies ANRIL as a non-coding RNA gene at 9p21, and the Results and Discussion link ANRIL expression to cell-cycle regulators in vascular smooth muscle cells. The paper also associates 9p21 variation with smooth muscle cell proliferation in atherosclerosis, but it does not demonstrate that ANRIL regulates adhesion or apoptosis. The citing sentence attributes its endometriosis point to other references, not this source. (LLM, conf=0.86)

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.
