Inhibition of M2 tumor-associated macrophages polarization by modulating the Wnt/β-catenin pathway as a possible...

The problem of liver cancer is becoming increasingly important due to the epidemic of metabolic diseases and persistent high alcohol consumption. This determines great attention to the development and improvement of methods for early diagnosis and treatment of liver cancer. Huang et al presented a study in the World Journal of Gastroenterology, in which they showed that the use of the traditional Chinese medicine Calculus bovis (CB) can suppress tumor growth in mice by inhibiting M2 tumor-associated macrophages (TAM) through modulating the activity of the Wnt/β-catenin pathway. The interaction of CB components with the Wnt/β-catenin pathway, M2 TAM polarization, and tumor dynamics were studied using network pharmacology, transcriptomics, and molecular docking. It is now generally accepted that the polarization of TAM and the differentiation of the functions of M1 and M2 phagocytes are of great importance for the progression of neoplasms. It is assumed that M2 TAM promote proliferation and migration of tumor cells. Attempts to medicinally influence the Wnt/β-catenin pathway in order to modulate phagocyte polarization now belong to one of the most promising areas of immunotherapy of oncological diseases. Undoubtedly, the work of the Chinese authors deserves attention and further development.
