Figure 8. ShRNA-mediated suppression of PQBP1 inhibits lipid storage in white adipocytes.

Figure 8

A) Western blot shows that PQBP1-shRNA-IRES-ZsGreen plasmid suppresses PQBP1 protein in primary mouse white adipocytes. Non-silencing shRNA (ns-ShRNA) was used as a control. The band intensities are corrected with GAPDH and standardized with non-transfected cells (NT). B) Primary white adipocytes were stained by Oil Red after transfection with PQBP1-shRNA-ZsGreen or non-silencing shRNA-ZsGreen plasmid. Non-transfected cells (arrowheads) possess large lipid droplets while PQBP1-shRNA-transfected cells (green) show small granules (arrows). Non-silencing shRNA-transfection did not affect the size of lipid granules (arrows in lower panels).
