ABSTRACT
Objective@#To find the different electrophoretic profiles of prion protein in carcinous and individual pericarcinous tissues in lysates of gastric, colon, liver, lung, thyroid, and laryngeal cancers.@*Methods@#Sodium dodecyl sulfate polyacrylamide gel electrophoresis (SDS-PAGE) and Western blot were used to test the amounts and electrophoretic patterns of total PrP and the tolerance of PK (protease K) digestion among six various cancer tissue types.@*Results@#A mass of PrP signals with a large molecular weight were identified in the homogenates of peripheral tissues. The amounts and electrophoretic patterns of total PrP did not differ significantly between carcinous and pericarcinous tissues. PrPs in all types of the tested cancer samples were PK sensitive but showed diversity in the tolerance of PK digestion among various tissue types.@*Conclusions@#The study revealed that the included electrophoretic patterns of carcinous and pericarcinous tissues were almost similar. Unlike PrP-specific immunohistochemical assay, evaluation of PrP electrophoretic patterns in the peripheral organs and tissues by Western blot does not reflect tumor malignancy.
