Figure 2A represents the IHC staining of FAK and VEGFR2 in all breast cancer tissues, and the frames are TNBC subtypes. Figure 2B shows high expression and low expression of FAK and VEGFR2 in the same patients. We found that there was a positive correlation between FAK and VEGFR2 protein expressions in TNBC subtypes, which is similar with the analytic results from the public database (Table 1), suggested that FAK gene and protein expressions are associated with VEGFR2 gene and protein expressions. This evidence concerns the gene PTK2 and breast cancer.
