ABSTRACT
OBJECTIVE@#To investigate the differential expression of microRNA (miRNA) in colon between ulcerative colitis (UC) and ulcerative colitis related colorectal cancer (UCRCC).@*METHODS@#An UC mouse model was built by dextran sodium sulfate, and an UCRCC mouse model by dextran sodium sulfate and 1,2-diformylhydrazine. RNAs were extracted from the colon, purified and hybridized with fluorescence-labeled miRNA oligonucleotide gene chip. Real-time fluorescence quantitative PCR was used to verify the expression variation of miRNA. SAM was employed for the data analysis.@*RESULTS@#The up-regulated miRNAs in colon cancer included has-miR-194, has-miR-215, has-miR-93, has-miR-192, has-miR-92a, has-miR-29b, and has-miR-20a (median false discovery rate<5%), while the down-regulated miRNAs were has-miR-1231, has-miR-195, has-miR-143, and has-miR-145 (median false discovery rate<5%).@*CONCLUSIONS@#Significant differential expression of miRNA was found between the UC mouse and UCRCC mouse, which may be related to the onset, erosion and transfer of colorectal cancer.
