The expression of CCL11/eotaxin, CCR3 receptor and eosinophil peroxidase in tumor tissue in gastric and colon cancers
The purpose of the study was to analyze the expression of CCL11/eotaxin, CCR3 receptor to eotaxin and eosinophil peroxidase (EXP) in tumor tissue and its relation to tissue eosinophilia in gastric and colon cancers.Materials and methods. 52 patients with gastric cancer and 55 patients with colon can...

| description | The purpose of the study was to analyze the expression of CCL11/eotaxin, CCR3 receptor to eotaxin and eosinophil peroxidase (EXP) in tumor tissue and its relation to tissue eosinophilia in gastric and colon cancers.Materials and methods. 52 patients with gastric cancer and 55 patients with colon cancer were examined. The material of the study was samples of malignant tumors of the stomach and large intestine obtained during a surgery. The expression of CCL11/eotaxin, CCR3 and EXP in the tumor tissue was evaluated by immunohistochemical method. For statistical processing of the results, one-factor dispersion and correlationregression (by Spearman) methods of analysis were used.Results. High expression of CCL11/eotaxin by tumor cells is typical of stomach and colon cancers with eosinophilic infiltration of the tumor tissue. The CCR3 receptor to eotaxin on the cell membrane of infiltration of the tumor tissue in gastric and colon cancers is found in 100% of cases. Expression of CCR3 (at stomach cancer) and EXP (at stomach and colon cancers) by cells of the tumor microenvironment with eosinophilic granulocytes infiltration is significantly higher than in the cells of the tumor microenvironment without eosinophilic infiltration.Conclusion. Tissue eosinophilia in gastric and colon cancers develops due to the ability of transformed malignant cells to produce CCL11/eotaxin that mediates the attraction of CCR3-expressing eosinophil granulocytes in the tumor tissue. High level of EPX (marker enzyme of eosinophils) expression by cells of tumor microenvironment in the gastric and colon cancers with tissue eosinophilia suggests the expressed cytotoxic potential of eosinophilic granulocytes, which can be directed against tumor cells. |
