PTK6 is up-regulated in BC tissues. (A) Upregulated PTK6 mRNA expression in 15 matched tumor and paracancerous epithelium tissues. (B) Western blots show significantly upregulated protein expression of PTK6 in 15 pairs of resection specimens from BC patients. (C) The relative quantity of PTK6 protein was determined by densitometric analysis. (D) Immunohistochemical representative images of PTK6 expression in BC samples (a) BC, scored as (-); (b) BC, scored as (+); (c) BC, scored as (++); (d) BC, scored as (+++) (scale bar, 100 µm).
