Fenretinide treatment increases STRA6 expression: stimulated by retinoic acid 6 (STRA6) messenger RNA (mRNA) fold expressions increase significantly when the cells were treated with fenretinide for 6 days. CRBP1 was also induced, nearing significance (P = .05). There was no change in cellular retinoic acid binding protein 2 (CRABP2) or fatty acid binding protein 5 (FABP5) expression. Results represent the mean ± standard error of the mean (sem) from 6 independent experiments using tissues from different subjects. NS indicates not significant.
