Genome-wide expression analysis of Middle Eastern colorectal cancer reveals FOXM1 as a novel target for cancer therapy.

To identify genes potentially playing an important role in the progression of colorectal carcinoma (CRC), we screened global gene expression using cDNA expression array on 41 CRC tissue samples and 25 noncancerous colorectal tissue samples. Among the up-regulated genes, forkhead box M1 (FOXM1) has been shown to play a critical role in pathogenesis of various malignancies. Using immunohistochemistry on 448 Saudi CRC samples in tissue microarray format, FoxM1 protein overexpression was seen in 66% of CRC tissues and was significantly associated with poorly differentiated and highly proliferative tumors (P = 0.

A modern regimen of pre-operative concurrent chemo-radiation therapy in locally advanced rectal cancer.

Purpose: To evaluate the efficacy and toxicity of preoperative concurrent capecitabine and radiotherapy in the treatment of resectable locally advanced rectal cancer (LARC).

Materials And Methods: We conducted a phase II trial to assess pathological complete response, tumor downstaging, toxicity and survival of capecitabine (825 mg/m(2) orally, twice daily) with radiotherapy (50.4 Gy/28 fractions) in 31 patients with LARC (cT3/T4 or N+) staged by endoscopic ultrasound (EUS).

Role of Nigella sativa and a number of its antioxidant constituents towards azoxymethane-induced genotoxic effects and colon cancer in rats.

This study examined the chemopreventive effect of Nigella sativa and some of its antioxidant constituents on a number of colon cancer biomarkers in rats induced with azoxymethane (AOM). Sixty male Sprague-Dawley rats were randomly assigned into ten subgroups: vehicle (1-5) and experimental (6-10). The rats in each group were fed one of the following diets: basal diet, (200 mg/kg) Nigella sativa, (0.

Bortezomib (Velcade) induces p27Kip1 expression through S-phase kinase protein 2 degradation in colorectal cancer.

S-phase kinase protein 2 (SKP2), an F-box protein, targets cell cycle regulators including cycle-dependent kinase inhibitor p27Kip1 via ubiquitin-mediated degradation. SKP2 is frequently overexpressed in a variety of cancers. We investigated the role of SKP2 and its ubiquitin-proteasome pathway in colorectal carcinoma using a panel of cell lines, clinical samples, and the NUDE mouse model.

Postoperative perineal hernia.

Large perineal hernia is an uncommon complication following abdominoperineal resection of the rectum, but it does present a difficult surgical dilemma. Repair of this hernia is a challenging surgical problem. Various methods of repair have been proposed and include an abdominal, perineal, or combined abdominoperineal approach to the hernia.
