Clinical Association of CD44 Expression with Proliferative Activity and Apoptotic State in Egyptian Patients Suffering from Ulcerative Colitis and Colorectal Carcinoma

BACKGROUND AND AIM: Cancer stem cell markers were thoroughly investigated as a promising strategy for the prediction of patient outcome and therapeutic response. The prospective role of CD44 cell adhesion molecule in tumorigenic potential and its association with the proliferative activity and apopt...

description BACKGROUND AND AIM: Cancer stem cell markers were thoroughly investigated as a promising strategy for the prediction of patient outcome and therapeutic response. The prospective role of CD44 cell adhesion molecule in tumorigenic potential and its association with the proliferative activity and apoptotic status of Egyptian patients with ulcerative colitis (UC) and colorectal cancer (CRC) were investigated in this study. MATERIAL AND METHOD: Flow cytometric analyses of CD44, DNA cell cycle, and apoptosis identified by Annexin V/PI were performed on colonic tissue specimens obtained from 44 CRC patients, 36 UC patients, and 30 controls. RESULTS: The CRC patients showed overexpression of CD44 marker (p < 0.0001) in comparison with UC and control groups. Regression analysis identified CD44 marker as an independent predictor for tumor staging and grading (p < 0.0001) of CRC patients. The CD44 expression was positively correlated with tumor stage (r = 0.656), tumor grade (r = 0.645), and the proliferative activity of DNA cell cycle (S phase, r = 0.396). However, CD44 expression was negatively correlated with early apoptosis (r = - 0.525). CONCLUSION: According to our findings, there was a significant and positive association between CD44 dysregulated expression and S phase of DNA cell cycle but a negative association with early apoptosis in CRC patients, suggesting CD44 role in apoptosis suppression reducing the tumor growth reserve.
