The qRT-PCR was performed using RT2 Profiler PCR Array Human Glycosylation (Qiagen) or custom primers for genes not repre- sented on the array (Dataset S1). Fold change (miR-treated/scramble) was calculated by taking the average relative expression of miR-treated samples (n = 4 independent experiments, normalized to GAPDH) over the average SI CORRECTION relative expression of the scramble treated cells (n = 4 independent experiments, normalized to GAPDH). Where the fold change was less than 1, the negative inverse is shown. P values for treated vs. scramble were calculated using Student’s t test. Statistically significant (P ≤ 0.05) down-regulation is in bold; up-regulation is underlined. GAGs, glycosaminoglycans; NC O-linked, noncanonical O-linked; See Table S1 for glycan type distribution. *Genes for which luciferase data were obtained (Fig. 1).
