Figure Lengend Snippet: Peretinoin inhibits human cardiovascular cell calcification without inducing liver cell APOC3 secretion. (A) APOC3 and (B) APOA1 mRNA levels and secreted protein in HepG2 treated for 24 hours with 0.1% DMSO vehicle (control), 1 μmol/L ATRA, 1 μmol/L 9-cis retinoic acid (9-cis RA), 1 μmol/L peretinoin, 13-cis retinoic acid (13-cis RA), or 1 μmol/L AGN 193109 (AGN). (C) CYP7A1 and (D) HNF4α, PPARGC1α mRNA levels in HepG2 cells treated for 24 hours. Alizarin red stain and relative quantification for (E) primary human coronary artery SMC and (F) VIC treated for three weeks, and (G) primary human femur osteoblasts treated for one three weeks in CM, OM, or PM with DMSO vehicle (0.01%), 1 μmol/L peretinoin, or 1 μmol/L ATRA. (H) RAR siRNA knockdown validation by mRNA level quantification, and Alizarin red stain and relative quantification for primary human femur osteoblasts treated for two weeks in OM with negative control, RARα, RARβ, or RARγ siRNA. Error bars indicate STDEV of mean. aP < 0.0001 vs control, bP < 0.0001 vs peretinoin, cP < 0.0001 vs AGN, dP < 0.001 vs control, eP < 0.001 vs peretinoin, fP < 0.01 vs peretinoin, gP < 0.01 vs control, hP < 0.01 vs AGN, iP < 0.001 vs AGN, *P < 0.05, **P < 0.01, ***P < 0.001, ****P < 0.0001 analyzed by ANOVA or Student’s t-test; n = 6 independent experiments for HepG2 and n = 3 donors for primary human VIC, SMC, and osteoblasts.
Article Snippet: Cell culture Human coronary artery SMC (PromoCell, Heidelberg, Germany) were expanded in Smooth Muscle Cell Growth Medium 2 (PromoCell) supplemented with epidermal growth factor (0.5ng/mL), insulin (5μg/mL) basic fibroblast growth factor- B (2ng/mL), and 5% fetal bovine serum, and cells were used between passages 3 and 8.
