Expression of genes involved in the UPR in HT29, HT29/Tun and HT29/MDR cells. ERAD: ER-associated degradation; UPR: unfolded protein response; ERQC: ER-quality control. Fold-Change (2^(− Delta Delta Ct)) is the normalized gene expression (2^(− Delta Ct)) in HT29/Tun or HT29/MDR cells, divided the normalized gene expression (2^(− Delta Ct)) in HT29 cells (n = 4), where Ct is the threshold cycle in qRT-PCR. Fold-change values greater than 1 indicate up-regulation, fold-change values less than 1 indicate down-regulation. The p values are calculated based on a Student’s t-test of the replicate 2^(− Delta Ct) values for each gene. p < 0.05 was considered significant. Genes significantly up- or down-regulated more than 2-fold either in HT29/Tun or HT29/MDR cells are in bold characters. (XLSX 16 kb)
