Figure Lengend Snippet: A) miRNA microarray profiles were performed on RNA extracted from HT-29 cells treated with vehicle or 100 μM ACh for 4 h. Data were normalized using the global Lowess regression algorithm and are expressed as log base 2 transformed ratios of the sample signal to the control reference pool signal. miRNAs with statistically significant changes (p<0.05) after ACh treatment are shown in the heat map; red represents increased expression compared to the pooled reference control, and green represents decreased expression. B) Changes in miR-21, miR-221, and miR-222 expression were confirmed by qPCR in HT-29 and H508 human colon cancer cells. Results are means ± SE, n = 4. *, indicates p<0.05 for the test sample compared to control. C) Expression of miR-21, miR-221, and miR-222 in sporadic colonic cancers and adjacent normal-appearing tissue were measured by microarray. Results are means ± SE, n = 4. *, indicates p<0.05 for expression in cancer compared to normal.
Article Snippet: Human miRNA profiles were analyzed using Exiqon miRNA array 7th Gen (Product #208500) for HT-29 cells and mirVana miRNA Bioarrays v. 2 (Thermo Fisher Scientific) for human colon samples according to the manufacturer’s instructions.
