| Research Abstract |
The difference of inflammatory microenvironment between ovarian cancers and endometriosis was investigated. We detected three CXCR3 variants in human tissues. Quantitative analyses revealed differential expressions of three variants. CXCR3-alt was upregulated and CXCR3B was downregulated in caners compared with endometriosis. In situ hybridization demonstrated preferential expression of CXCR3B in non-cancerous vessels and CXCR3-alt was detectable mainly in tumor vessels. Collective data suggest that differential expression patterns of CXC chemokines and CXCR3 variants are involved in inflammatory microenvironments of ovarian cancers and cancer-associated conditions.
