Abstract:
We analyzed the content of β-catenin fractions and activity and content of proteasomes in the tissues of patients with non-small cells lung cancer. The content of β-catenin fractions was elevated and proteasome-dependent proteolysis in the tumor tissue was enhanced in comparison with the corresponding unchanged lung tissue. A negative regression relationship of caspase-like activity of proteasomes and a positive correlation between the content of proteasomes and both fractions of β-catenin were found. We hypothesize that proteasomes are involved in the degradation of β-catenin due to caspase-like activity.
