Frequent somatic gene conversion as a mechanism for loss of heterozygosity in tumor suppressor genes.

Genome Res 2022 May 26. Epub 2022 May 26.

SOKENDAI, The Graduate University for Advanced Studies

The major processes to carcinogenesis include inactivation of tumor suppressor genes (TSGs). While Knudson's two-hit model requires two independent inactivating mutations, perhaps more frequently, inactivation of a TSG can occur through loss of heterozygosity (LOH) of one inactivating mutation. Deletion and uniparental disomy (UPD) have been well documented as the mechanisms of LOH, but the role of gene conversion is poorly understood. Read More

Senescence-induced endothelial phenotypes underpin immune-mediated senescence surveillance.

Genes Dev 2022 May 26. Epub 2022 May 26.

Cancer Research UK Cambridge Institute, University of Cambridge, Cambridge CB2 0RE, United Kingdom.

Senescence is a stress-responsive tumor suppressor mechanism associated with expression of the senescence-associated secretory phenotype (SASP). Through the SASP, senescent cells trigger their own immune-mediated elimination, which if evaded leads to tumorigenesis. Senescent parenchymal cells are separated from circulating immunocytes by the endothelium, which is targeted by microenvironmental signaling. Read More

Bufalin stimulates antitumor immune response by driving tumor-infiltrating macrophage toward M1 phenotype in hepatocellular carcinoma.

J Immunother Cancer 2022 May;10(5)

Institute of Infectious Disease, Shuguang Hospital Affiliated to Shanghai University of Traditional Chinese Medicine, Shanghai, 201203, People's Republic of China

Background: Immunotherapy for hepatocellular carcinoma (HCC) exhibits limited clinical efficacy due to immunosuppressive tumor microenvironment (TME). Tumor-infiltrating macrophages (TIMs) account for the major component in the TME, and the dominance of M2 phenotype over M1 phenotype in the TIMs plays the pivotal role in sustaining the immunosuppressive character. We thus investigate the effect of bufalin on promoting TIMs polarization toward M1 phenotype to improve HCC immunotherapy. Read More
