ORP8 or ORP3 were overexpressed by infecting cells on day 10 with control (Blank) or ORP (Ad-ORP8, Ad-ORP3) adenoviral vectors, and collected for analysis on day 13. SGBS preadipocytes were transduced with an ORP11 shRNA (Sh-ORP11) or non-targeting (Sh-NT) shRNA lentivirus, followed by differentiation for 22 days. A. Western blots of total cell protein (10 µg/lane); ORP11, after 22 days of differentiation; ORP8 and ORP3, after 72 h of adenoviral transduction. The blots were probed with anti-β-actin as a loading control. B. The impacts of ORP11 silencing or ORP8/ORP3 overexpression on the mRNA levels of adipocyte differentiation markers adiponectin, aP2, leptin and PPARγ. In cells with ORP11 stably silenced also ORP8 and ORP3 mRNAs were quantified. The results are shown as fold changes relative to cells infected with the corresponding control viruses, and represent mean ± S.E., n = 3; *p<0.05. C. The cellular triglyceride concentration was measured by using an enzymatic assay. The results were normalized for total cell protein and are presented relative to cells infected with the corresponding control viruses (mean ± S.E., n = 3; *p<0.05, **p<0.01).
