Abstract
BACKGROUND The MCP-1/CCR2 axis is one of the major chemokine signaling pathways that play a crucial role in the tumor microenvironment and has been involved in triggering various tumor progression mechanisms, such as increasing the immunosuppressive cells recruitment and promoting tumor cell proliferation and invasiveness. AIM The current study investigated the association of MCP1 (rs1024611) and CCR2 (rs1799864) genes variants with the risk as well as prognosis of colorectal cancer (CRC) and colorectal liver metastases (CRLM). SUBJECTS AND METHODS A retrospective cohort study involved 408 patients (284 CRC and 124 CRLM), and 284 healthy control was conducted. Genotyping of selected polymorphisms was performed by PCR-RFLP assays and confirmed by microchip and capillary electrophoresis. RESULTS The results highlighted a positive association between MCP1 rs1024611 (non-AA) and CCR2 rs1799864 (GA) genotypes with increased CRC and CRLM risk. Correlation between SNPs and clinicopathological characteristics revealed a positive association between MCP1 rs1024611 and CCR2 rs1799864 (dominant model) and CRC poor prognosis features. Kaplan-Meier survival analysis revealed a significant association between MCP1 rs1024611 non-AA carriers and decreased survival rate. Neoadjuvant treatment showed an improvement in CRC and CRLM survival rates among carriers of MCP1 and CCR2 wild-type genotype. FOLFIRI chemotherapy exhibits reduced survival rates for patients who carried mutated genotypes of MCP1 and CCR2 polymorphisms. CONCLUSION Considering our results, we suggest That both MCP1 and CCR2 polymorphisms may constitute independent factors for CRC and CRLM occurrence and can be helpful targets for an efficient therapeutic approach.

Abstract
BACKGROUND Recent studies suggest that SDF-1 and CXCR4 are expressed in certain cancer cells, and malignant cells use this chemokine/receptor system to promote tumor progression and metastasis. However, the pathophysiological significance of their expression in colorectal cancer (CRC) tissue has not been fully elucidated. OBJECTIVE The purpose of this study was to assess SDF-1/CXCR4 expression and to explore its contribution to colorectal cancer. METHODS We examined SDF-1 and CXCR4 mRNA expression in 124 primary colorectal tumour and 35 liver metastases tissues and matched adjacent noncancerous tissues by reverse transcriptase PCR (RT-PCR). Furthermore, their expression was analyzed by immunohistochemistry. The relationship between SDF-1/CXCR4 expression and clinicopathological features were analyzed by appropriate statistics. X2 test and Kaplan-Meier analysis were used to investigate the correlation between the ligand-receptor expression and prognosis of colorectal cancer patients. RESULTS The relative mRNA expression of SDF-1 and CXCR4 was significantly elevated in colorectal cancer tissues as compared with adjacent noncancerous tissues (P < 0.001). The high expression of proteins expression in colorectal cancer tissues was significantly correlated with tumor grade (P = 0.0001), clinical stage (P < 0.05), and lymphatic invasion (P < 0.05). Furthermore, patients with CXCR4 nuclear-type expression showed more frequent lymph node metastasis (p = 0.021), advanced clinical stage (p = 0.001) and lymphatic invasion (p = 0.03) than those with cytoplasm staining-type. Kaplan-Meier survival analysis revealed that high expression of the couple SDF-1/CXCR4 correlated with poor prognosis of colorectal cancer patients (P < 0.001). CONCLUSION SDF-1 and CXCR4 may play an important role in the progression of colorectal cancer. The present data suggest that there is a significant association between SDF-1/CXCR4 to enhance the liver metastases causing poor prognosis. Those proteins may potentially be used as an independent biomarker for the prognostic evaluation of colon cancer in the Tunisian cohort.

Abstract
The aim was to evaluate the relationship between SDF-1G801A polymorphism and its immunohistochemical expression in colorectal cancer tissues in the Tunisian cohort. The molecular and immunohistochemical analysis showed that SDF-1G801A polymorphic variant was higher in CRC patients with TNM stage II and III, the SDF-1 expression was significantly increased from normal mucosa to primary tumor (p < 0.05). CRC patients have higher frequency of A allele (52.01%) than controls (26.8%) (P = 0.0001). Thus, SDF-1 polymorphism is a risk factor of colorectal cancer susceptibility in our population, the polymorph genotype of SDF-1 maybe associated with clinical manifestations in CRC patients in Tunisia.

Abstract
One of the most important pathways which are frequently affected in colorectal cancer is p53/ (MDM2)/p14ARF pathway. We aim to determine the methylation pattern of p14/ARF in relation to mutation of p53. This correlation was studied to investigate whether their alterations could be considered as a predictor factor of prognosis in colorectal cancer and whether it can be useful in early-stage diagnosis. Statistical analyses show that p14/ARF hypermethylation was correlated with rectum location (p = 0.004), primary TNM stage (p = 0.016), and advanced Astler–Coller stage (p = 0.024). The RT-PCR that revel 31 % of patients did not express p14/ARF mRNA or at very low level. A high concordance between CpG hypermethylation and the low levels (p < 0.005) was shown. In addition, our analyses demonstrate that patients with mutation in the p53 gene have a lack of the protein expression (p < 0.005). This category with negative expression of p53 had a shorter survival rate (p < 0.005). On the one hand, MSP pattern of p14/ARF were correlated with a lack of p53 expression (p = 0.007). We found that p53/p14ARF pathway was frequently deregulated among our patients. In our study, we demonstrate that hypermethylation of p14/ARF occurs early during CRC tumorogenesis. However, we did not find correlation between p14/ARF and survival. These results suggest that p14/ARF methylation pattern may constitute a predictor factor of CRC in early stage but it could not be considered as a prognostic factor. On the other hand and because of the reversibility of the methylation mechanism, it may be appropriate to target the demethylation of p14/ARF to develop new drogues for CRC.

Abstract
BACKGROUND About 10% to 15% of sporadic colorectal cancers demonstrate high level of microsatellite instability that is generally associated with aberrant methylation of hMLH1 promoter. AIM To investigate the association between MSI status, hMLH1 protein expression and methylation status of the hMLH1 promoter in a cohort of Tunisian sporadic colorectal cancer. METHODS Expression of MLH1 and MSH2 was determined by immunohistochemistry and the MSI status was analysed by microfluid-based on-chip electrophoresis. Methylation of the hMLH1 gene promoter was determined by methylation-specific PCR. RESULTS Of the 150 colorectal cancers 57% were MSS, 28% were MSI-L and 15%were MSI-H. MSI-H tumors were more frequently right-sided, exhibited a stage III of TNM and tended more to be mucinous. The MSI status had no effect on overall patient survival. Most of the MSS/MSI-L 79% cancers were unmethylated at the hMLH1 promoter, while 26% MSI-H cancers were unmethylated. 84% of MSS and MSI-L expressed MLH1 and 52% of MSI-H expressed MLH1. Of the methylated MSI-H cases, 35% expressed MLH1 protein while 100% of the unmethylated MSI-H were positive for MLH1 staining. Of 11 MSI-H cancers with loss of MLH1 expression, all cases were also methylated while 50% MSI-H cancers with positive immunostaining for MLH1 were methylated at the hMLH1 promoter. CONCLUSION Our study showed that MSI-H phenotype was mucinous, right-side and exhibit stade III of TNM. The relative correlation of MLH1 expression and promotor hypermethylation of hMLH1 for the MSI status is similar to that reported for several study.
