Title of the item:

Expression profile of NF-κB regulated genes in sporadic colorectal cancer patients.

Colorectal cancer (CRC) is the fourth leading worldwide cause of cancer-associated mortalities. Nuclear factor-κB (NF-κB) is a transcriptional regulator of multiple genes associated with CRC. Tumor tissue were compared with normal adjacent mucosa from 30 sporadic patients with CRC were investigated. A total of 8 non-CRC patients were analyzed as a control group. In the present study, the protein expression of NF-κB/p65 was detected by immunohistochemistry, and the gene expression profiles of cyclin D1 (CCND1), prostaglandin-endoperoxide synthase 2, vascular endothelial growth factor A, matrix metallopeptidase 9, BCL2 apoptosis regulator (BCL2), BCL2 like 1, nitric oxide synthase 2, tumor necrosis factor and arachidonate lipoxygenase were detected by reverse transcription-quantitative polymerase chain reaction. NF-κB/p65 and genes expression profiles were classified according to tumor-node-metastasis (TNM) clinicopathological parameters, followed by statistical analysis. Higher protein expression of NF-κB/p65 in the cytoplasm of tumor tissues compared with adjacent normal mucosa was reported; this increment was positively associated with all clinicopathological parameters, except for tumor localization site.
