Transcriptomic and miRNA profiling of colorectal adenocarcinoma and healthy mucosa

ABSTRACT: The ACTB gene, traditionally considered a reference gene, exhibits transcriptional instability in colorectal cancer tissues. The aim of this study was to evaluate the transcriptomic profile of colorectal adenocarcinoma, with a specific focus on structural genes and their regulatory networks within the tumor microenvironment. We conducted high-throughput mRNA profiling (Affymetrix GeneChip Human Gene 2.0 ST) of colorectal tumor tissues and healthy colonic mucosa. In parallel, a pilot microRNA screening (Affymetrix GeneChip miRNA 4.0) was performed on a subset of samples to uncover potential tumor-specific rewiring of regulatory networks involving ACTB and tumor-suppressive miRNAs.

Effect of mutant p53 R282W on miRNA expression

Project description:The H1299 cells stably transfected with mutp53 R282W or the control vector were respectively analyzed by Affymetrix GeneChip miRNA 4.0 microarray with three biological replications. The labeled RNA was consequently hybridized for sixteen hours to an Affymetrix GeneChip miRNA array according to the product manual. Microarrays were washed and stained in the Affymetrix Fluidics Station 450, and scanned on the Affymetrix G3000 GeneArray Scanner.

Expression data of miRNA profile from colorectal cancer and the adjacent normal tissues infected with F. nucleatum

Project description:Expression data of miRNA profile from colorectal cancer and the adjacent normal tissues infected with F. nucleatum. Colorectal cancer(CRC) is among the most common cancer types in the world and one of the most lethal cancers. Fusobacterium nucleatum (F. nucleatum) plays an etiologic role in the development of colorectal cancer, but specific tumor molecules involved in the progression of CRC induced by F. nucleatum is not clear. This study investigated some miRNAs and the genes involved in the progression of F. nucleatum-induced colorectal cancer by Affymetrix miRNA microarray technology. We used microarrays to detail the global programme of gene expression underlying cellularisation and identified distinct classes of up-regulated and down-regulated genes between Colorectal cancer and the adjacent normal tissues (CONTROL) infected without F. nucleatum . The miRNA array was performed using the affymetrix GeneChip® miRNA 3.0 Array (Affymetrix, Santa Clara, California, United States). The chip was processed using a commercial Affymetrix array service (GeneTech Biotechnology Limited Company, Shanghai, China). The affymetrix GeneChip® miRNA 3.0 Array contains 2,999 probe sets unique to human, mouse and rat pre-miRNA hairpin sequences, 2,216 human snoRNA and scaRNA probe sets and covers 153 organisms (19,724 probe sets). Raw data sets were extracted from all Cel files (raw intensity file) after scanning of slides. These raw data sets were separately analyzed using Expression Console and GeneSpring GX12.5 software followed by differential miRNA expression, fold change & cluster analysis.
