Serum TK1 activity and TK1 protein concentrations in different clinical samples. (A) Serum thymidine kinase 1 (sTK1) activity (pmol/min/mL) in sera from healthy dogs (•) and dogs with mammary tumors (■). The error bars represent means ± standard deviation (SD). (B) Serum TK1 protein levels in sera from healthy dogs (•) and dogs with canine mammary tumors (CMTs) (■). (C) Comparison of sTK1 activity in healthy dogs (•) and dogs with benign (■) and malignant (▲) CMTs. (D) Comparison of sTK1 protein levels in healthy dogs (•) and dogs with benign (■) and malignant (▲) mammary tumors. The error bars represent means ± standard deviation (SD).
