Salivary Protein Profiles among HER2/neu-Receptor-Positive and -Negative Breast Cancer Patients: Support for Using Salivary Protein Profiles for Modeling Breast Cancer Progression
It illustrates the presence of profilin-1 in the SKBR3 and HSG cell lysates and saliva sampled from healthy, benign, and malignant tumor patients. Profilin is a downregulated protein in the presence of malignancy, and it is visualized by the lighter bands associated with malignancy. It is also worth noting that the Her2/neu-receptor-negative band is darker than the Her2/neu-receptor-positive counterpart suggesting further downregulation of the profiling-1 protein.
