Article Title: Expression of the CXCL12/CXCR4 and CXCL16/CXCR6 axes in cervical intraepithelial neoplasia and cervical cancer
doi: 10.5732/cjc.012.10063
Figure Lengend Snippet: Immunohistochemistry was used to detect the expression of CXCL16 and CXCR6 in tissue sections. Sections of invasive SCC, CIN3, CIN2, and normal cervix were stained for CXCL16 and CXCR6 (×200). Both CXCL16 and CXCR6 antigens are expressed in the epithelia and stroma of neoplastic squamous and glandular lesions. The epithelial staining is clearly intracellular and well defined, whereas stromal staining is generally diffuse and weak. CXCL16 and CXCR6 exhibit strong expression in the cytoplasm and membrane throughout the full thickness of the epithelium in SCC and CIN3. In contrast, CXCL16 or CXCR6 staining is decreased and confined to the basal layers of the epithelia in CIN2 lesions. The normal ectocervix shows weak staining for CXCL16 in epithelia and stroma but is consistently negative for CXCR6.
Article Snippet: After blocking with 7% horse normal serum for 30 min at room temperature, sections were incubated with mouse monoclonal anti-CXCL12 (R&D, dilution 1:25), mouse monoclonal anti-CXCR4 (R&D, dilution 1:80), goat polyclonal anti-CXCL16 (R&D, dilution 1:10), or mouse monoclonal anti-CXCR6 (R&D, dilution 1:40) overnight at 4°C.
