Western blot analysis of HGSC tissue extracts using the same monoclonal antibody (MAB160) further confirmed its specificity, showing two distinct bands between 35 and 40 kDa representing the two splice variants CXCR3-A and CXCR3-B (Figures 1b, band at 55 kDa is a remnant of the loading control α-tubulin).18 In cases of CXCR3 positivity, 100% of tumor cells displayed CXCR3 expression. This evidence concerns the gene CXCR3 and neoplasm.
