Project description:To clarify the effect of miRNAs, we carried out a gene expression microarray analysis using GIST-T1 cells transfected with a miR-335 mimic or a negative control. We found that 1,095 probe sets (853 unique genes) were downregulated (>1.5-fold) by ectopic miR-335 expression. GIST-T1 cells were transfected with a mirVana miR-335 mimic (Ambion) or a mirVana miRNA mimic Negative Control #1 (Ambion). Forty-eight hours after transfection, total RNA extraction was carried out, and gene expression signatures were analyzed.
Project description:To clarify the effect of miRNAs, we carried out a gene expression microarray analysis using GIST-T1 cells transfected with a miR-34a mimic or a negative control. We found that 2,621 probe sets (1,933 unique genes) were downregulated (>1.5-fold) by ectopic miR-34a expression, including PDGFRA gene which was previously reported as a miR-34a target gene. GIST-T1 cells were transfected with a mirVana miR-34a mimic (Ambion) or mirVana miRNA mimic Negative Control #1 (Ambion).

Project description:To clarify the role of miR-186 in GIST, we carried out a gene expression microarray analysis using GIST-T1 cells transfected with a miR-186 inhibitor or a negative control. We found that 253 probe sets (229 unique genes) were upregulated (>1.5-fold) by inhibition of miR-186 in GIST-T1 cells.
