Opis:
Purpose: To evaluate the clinical significance of MMP-2 and TIMP-2 concentrations in the sera of patients diagnosed with colorectal cancer. Methods: The study group comprised 48 patients with colorectal carcinoma and 24 healthy controls. The serum concentration of MMP-2 and TIMP-2 proteins was evaluated by the ELISA method. Results: The mean level of MMP-2 in the sera of patients with colorectal cancer was 39.4 ng/ml and was significantly lower compared with the control (p<0.001). A decrease in TIMP-2 protein in the sera of patients with colorectal cancer was also observed where its mean level was 132.3 ng/ml. The concentration of MMP-2 and TIMP-2 did not correlated with any clinicopathological parameters, except for the patients’ age. In addition, the concentration of MMP-2 in the sera of patients with CRC correlated negatively with the number of white blood cells in the blood and the prothrombin index. The concentration of TIMP-2 correlated positively with potassium and urea concentration in the blood. Conclusions: The results of our study indicate lack of clinical usefulness of determining the levels of MMP-2 and TIMP-2 in the sera of patients with colorectal cancer. However, these proteins play an important role in the carcinogenesis of colorectal cancer.

Opis:
Purpose: Recent literature data indicate a key role of apoptosis in the pathogenesis of inflammatory bowel disease. The aim of the study was to evaluate the expression of Bax, Bid, Bcl-2 and Bcl-xl in non-dysplastic and dysplastic epithelium in inflamated mucosa of patients with ulcerative colitis. Methods: The study consists of 18 patients with diagnosed ulcerative colitis. The expression of proteins was determined immunohistochemically. Results: Lack of Bax expression in normal epithelium of the inflamed intestinal mucosa (94.4%) and a weak expression of this protein were found in dysplastic glandular cells (67%). The Bax expression of dysplastic epithelium correlates with reduced severity of chronic inflammation (p<0.005). Bid expression in non-dysplastic glands was found in 67% of cases vs. 16% in dysplastic epithelium that was associated with the occurrence of epithelial erosions or ulcers (p<0.05). Moderate cytoplasmic expression of Bcl-xl was noted in 27.7% of patients in normal epithelium and in 66.1% within dysplastic lesions. Bcl-xl expression in dysplastic glandular cells correlated with the presence of neutrophils in the lamina propria (p <0.05). Conclusions: The immunohistochemical expressions of Bax, Bcl-2 and Bcl-xl increase and Bid protein expression decreases in dysplastic glandular tubes as compared to non-dysplastic intestinal epithelium in inflamed mucosa, which may suggest an imbalance of controlled cell death in ulcerative colitis.

Opis:
Purpose: Growth differentiation factor-15 (GDF- 15) protein belongs to a transforming growth factor-β family which determines the growth and differentiation of cells. In cancers, GDF-15 influences on the proliferation, differentiation, viability, migration and invasiveness of cancer cells. The aim of our study was to evaluate the expression of GDF-15 in the tissue and its levels in sera of patients with colorectal cancer. Materials and methods: The level of GDF-15 in the sera of 55 patients diagnosed with colorectal cancer was determined using the ELISA method whereas expression of this protein was performed by immunohistochemical method. Results: The mean value of GDF-15 levels in the sera of patients with colorectal cancer was significantly higher than in healthy control group (p<0.001). The expression of GDF-15 in the tissue was weak, moderate and strong in 23.6%, 15.7% and 60.7% cases, respectively. Statistical analysis showed that the expression of GDF-15 correlated with patients’ age (p<0.005) and non-mucinous type of cancer (p<0.001). The high GDF-15 levels in the serum was associated with tumor size (p<0.01) and distant metastases (p<0.05). Conclusions: According to our results, we postulate that the level of GDF-15 in serum can be use to assess the metastatic behavior of colorectal cancer
