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 studied the expression of mRNA and the level of CAP1 (adenylate cyclase-associated protein 1) and cofilin proteins in the tissues of patients with non-small cell lung cancer. The expression of mRNA and the level of CAP1 in tumor tissue increased during growth of the primary tumor and its metastasis. It was shown that with the growth of the primary tumor, the content of cofilin in the tumor tissue decreases against the background of increased expression of its mRNA; in regional metastasis, the content of cofilin and expression of the corresponding mRNA increased.
