CDKN2B-AS1 is downregulated in atherosclerosis. (A) RT-qPCR was used to detect the transcriptional level of CDKN2B-AS1 in atherosclerotic plaque and IMA tissues; n = 16; (B) RT-qPCR determination of transcription level of CDKN2B-AS1 in ox-LDL-exposed THP-1 macrophage-derived foam cells and THP-1 macrophages; * p < 0.05 vs. the IMA tissues or THP-1 cells; the measurement data were expressed in the form of mean ± standard deviation and analyzed by unpaired t-test, the experiment was repeated 3 times; IMA, internal mammary artery; THP-1, the human monocytic leukemia cell line; RT-qPCR, reverse transcription quantitative polymerase chain reaction; CDKN, cell-dependent kinase inhibitor.
