(Submitter supplied) We aimed to clarify the role of miR-200b in cisplatin (CDDP) sensitivity in bladder cancer (BCa). CDDP resistant T24 cells (T24RC) were transfected with a miR mimic negative control (NC) or a miR-200b mimic, after which cells were treated with or without CDDP. We found that ectopic miR-200b expression re-sensitized the T24RC cells to CDDP. Gene expression microarray analysis revealed that the combination of miR-200b and CDDP affected genes involved in CDDP sensitivity and cytotoxicity.

(Submitter supplied) To clarify the effect of miRNAs, we carried out a gene expression microarray analysis of SW780 cells transfected with a miR-137 precursor or a negative control. We found that 1,326 probe sets (1,016 unique genes) were downregulated (>2-fold) by ectopic miR-137 expression, including the previously reported miR-137 target genes CDK6, CDC42 and AURKA. Moreover, Gene Ontology analysis revealed that genes related to the cell cycle were significantly enriched among the affected genes.

(Submitter supplied) We found frequent epigenetic silencing of microRNA-34b/c in human colorectal cancer. Introduction of miR-34b/c into a colorectal cancer cell line induced significant changes in gene expression profile. We also found overlap between the genes downregulated by miR-34b/c and those downregulated by DAC. Keywords: dose response

(Submitter supplied) 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.

(Submitter supplied) 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.
