Project description:OCC-1 is one of the earliest annotated long noncoding RNAs (lncRNAs) in colorectal cancer (CRC). In our study, we found that knockdown of OCC-1 by shRNAs promotes CRC cell growth both in vitro and in vivo. To gain insight into the molecular function of OCC-1, we profiled the gene expression of Caco-2 cells after OCC-1 knockdown by microarray.
Project description:BORIS expresses abnormally in colorectal cancer cells. Both the expression and the copy number of BORIS are remarkably higher in colorectal cancer cells than in normal colon or rectal cells. BORIS is potential diagnosis, prognosis or therapeutic target for colorectal cancer. To expand our view of the signaling pathway related with BORIS, altered gene expression by BORIS knockdown was assessed by microarray assay. To study the gene regulation by BORIS knockdown, microarray assay was applied to screen the gene expression regulated by BORIS siRNA in colorectal cancer cells HCT116 and Caco-2
Project description:LC-MS/MS glycoproteomic analysis of EGFR N-glycosylation profile. EGFR immunoprecipitated from colorectal cancer cell lines SW48 (wild-type and ST6Gal1 overexpression) and Caco-2 (wild-type and ST6Gal1 knock-out)
Project description:MicroRNAs regulate the biological aggressiveness of colorectal cancer (CRC) cells and might serve as potential prognostic factors and therapeutic targets. In this study, we therefore globally profiled microRNAs associated with aggressive growth in CRC cells, in an attempt to identify novel prognostic biomarkers in CRC patients. In detail, two different CRC cell lines (Caco-2 and HRT-18) with completely different growth rates and different E-cadherin expression were profiled for differences in more than 1000 human microRNAs by using microarray technology. Two-condition experiment, HRT-18 vs. Caco-2. Biological replicates: 3, independently grown and harvested. On each array, one BR of HRT-18 cells was directly compared to one BR of Caco-2 cells (serving as reference sample). All hybridizations were repeated with reversed dye assignment (dye-swap) as technical replicates.

Project description:Interferon-induced transmembrane protein 1 (IFITM1) is one of the three members of the interferon-induced transmembrane family and has recently been identified as a new molecular marker in human colorectal cancer. However, its functional roles in colorectal cancer are still elusive. In this study, we investigate the gene expression profiling of HT-29 cells with IFITM1 knockdown. We revealed that several invasive- and carcinogenesis-related genes were differentially expressed. We transfected siRNAs targeting firefly luciferase and human IFITM1 mRNAs into HT-29 colorectal adenocarcinoma cells. At 72 h post-transfection, total RNA was harvested for microarray hybridization. A siLuc-transfected sample was used as the baseline control.
Project description:Whole genome microarray data were analyzed to describe the changes in gene transcription profile in human Caco-2 cancer cells under the influence of the extract from iodine-biofortified and non-fortified carrot and lettuce. These iodine-biofortified vegetables can be used as a functional food. Four-condition experiment: iodine-biofortified carrot, non-fortified carrot, iodine-biofortified lettuce, non-fortified lettuce vs. Caco-2 colorectal adenocarcinoma cell line. Three biological replicates and three technical replicates.

Project description:To reveal the effects of carnosine on Caco-2 cells, we have employed whole genome microarray to detect genes that showed significantly different expression when exposed to carnosine. Caco-2 cells were treated with 1 mM carnosine for 3 days.
