The effect of overexpression of a combination of genes on their abundance. RAW 264.7 cells were transiently transfected with ABCA1 + scavenger receptor type BI (SR-BI) + phospholipid transfer protein (PLTP) + CYP27A1 (A) or caveolin-1 (B). The abundance of individual proteins was assessed by Western blot and quantitated by densitometry as described in Materials and Methods. Numbers under the blots indicate increase of abundance of the indicated protein (fold, relative to mock-transfected cells).
