SMS2 deficiency significantly increased macrophage ABCA1, ABCG1, and SR-B1 protein levels. Macrophage lysates were subjected to SDS/PAGE and transferred to nitrocellulose membranes. Blots were probed with ABCA1, ABCG1, and SR-B1 antibodies. GAPDH was used as a loading control. Panel A, ABCA1, ABCG1, and SR-B1 fluorogram, which is representative of 3 independent experiments. Panel B, quantitative display of macrophage ABCA1, ABCG1, and SR-B1. Values are mean ± SD, N=4. *P<0.01.
