Tan IIA inhibits oxLDL-induced CD36 expression by inhibiting Nrf2 expression and PPARγ activity. (A, B) Effects of oxLDL on CD36 expressions at mRNA levels measured by qRT-PCR and protein levels detected by Western blot in macrophage, respectively; GAPDH, glyceraldehyde-3-phosphate dehydrogenase as an internal control. (C, D) Effects of Tan IIA on oxLDL-induced CD36 expressions at mRNA levels and protein levels in macrophages, respectively. (E) Effects of Tan IIA on oxLDL-induced caspase-1 activation in the cells detected by Western blot. (F) Effects of Tan IIA on oxLDL-induced IL-1β productions measured by ELISA in macrophages. (G, H) Effects of Nrf2 and PPARγ gene knockdown by siRNA on CD36 expression on the cell membrane, respectively, detected by flow cytometry, presented by mean fluorescence intensity (MFI). (I, J) Effects of Tan IIA on oxLDL-mediated Nrf2 expression measured by RT-PCR and oxLDL-mediated PPARγ activity measured by a commercial kit in the cells.
