Correction for: Silencing of long non-coding RNA H19 downregulates CTCF to protect against atherosclerosis by upregulating PKD1 expression in ApoE knockout mice


Figure 5. H19 is involved in atherosclerotic vulnerable plaque formation and intraplaque angiogenesis through down-regulating PKD1 by recruiting CTCF in ApoE knockout mice with AS. (A) The expression pattern of PKD1 in the aortic tissues of normal and AS mice determined by RT-qPCR. * p < 0.05 vs. the control group. (B) The overexpressing efficiency of H19, CTCF and PKD1 assessed by RT-qPCR. * p < 0.05 vs. the oe-NC + oe-NC + oe-NC group; # p < 0.05 vs. the oe-H19 + oe-CTCF + oe-NC group. (C) The atherosclerotic vulnerable plaque formation evaluated by HE staining (× 400) (The arrow referred to lipid vacuoles, * represented inflammatory cells and # indicated fractured smooth muscle). (D) The number of new blood vessels measured by Immunohistochemical staining (× 400) (The arrow referred to CD34-positive cells). (E) The protein levels of MMP-2, VEGF, p53 and TIMP-1 in atherosclerotic plaques normalized to GAPDH after transfection determined by Western blot analysis. * p < 0.05 vs. the oe-NC + oe-NC + oe-NC group. The data were measurement data and expressed by mean ± standard deviation. Data differences between two groups were analyzed by unpaired t-test; comparisons made among multiple groups were analyzed by one-way ANOVA. The experiments were repeated three times independently.
