Table 1. HPLC detection of the effect of CDKN2B-AS1 on cholesterol level in THP-1 macrophage-derived foam cells.

Group	TC (μg/mg cell protein)	FC (μg/mg cell protein)	CE (μg/mg cell protein)	CE/TC (%)
oe-NC	465.14 ± 12.34	188.22 ± 10.25	298.24 ± 14.05	64.10
oe-CDKN2B-AS1	289.21 ± 11.02^a	119.83 ± 9.32 ^a	162.79 ± 13.05 ^a	56.38

Note: TC, total cholesterol; FC, free cholesterol; CE, cholesterol ester; ^a, p < 0.05 vs. the oe-NC group; the measurement data is expressed in the form of mean ± standard deviation and analyzed by unpaired t-test, the experiment was repeated 3 times; THP-1, the human monocytic leukemia cell line; NC, negative control; CDKN, cell-dependent kinase inhibitor.
