The obtained antibody stainings were quantified by an experienced pathologist using the H-score system, which revealed a significant up-regulation of PTTG1 in the cytoplasmic (mean in tumor: 124.1, mean in control: 79.78, P: 3.97e-08) and nuclear (mean in tumor: 125.4, mean in control: 30.66, P: 4.35e-16) compartments of tumor cells in comparison to cells in paired pseudo stratified epithelia that were used as controls. Here, PTTG1 is linked to neoplasm.
