Fastest Time to Cancer by Loss of Tumor Suppressor Genes.
Irvine, United States. In Bull Math Biol, 23 Nov 2014
With the loss of tumor suppressor gene function known to be responsible for a high percentage of breast and colorectal cancer (and a good fraction of lung cancer and other types as well), it is important to understand how genetic instability can be orchestrated toward carcinogenesis.
DEAR1, a Novel Tumor Suppressor That Regulates Cell Polarity and Epithelial Plasticity.
Houston, United States. In Cancer Res, 26 Oct 2014
This review will highlight the role of the novel TRIM protein DEAR1 (annotated as TRIM62) in the regulation of apical-basal polarity and acinar morphogenesis as well as its function as a chromosome 1p35 tumor suppressor and negative regulator of TGFβ-driven epithelial-mesenchymal transition (EMT).
Coordinated regulation of protein synthesis and degradation by mTORC1.
Boston, United States. In Nature, 18 Oct 2014
Genetic activation of mTORC1 through loss of the tuberous sclerosis complex tumour suppressors, TSC1 or TSC2, or physiological activation of mTORC1 in response to growth factors or feeding resulted in increased NRF1 expression in cells and tissues.
Molecular genetics of clear-cell renal cell carcinoma.
Dallas, United States. In J Clin Oncol, Jul 2014
Several additional tumor suppressor genes have been identified near the VHL gene, within a region that is frequently deleted in ccRCC on chromosome 3p: SETD2, BAP1, and PBRM1.
Tumor Suppression and Promotion by Autophagy.
Santiago, Chile. In Biomed Res Int, Dec 2013
Specifically, tumor suppressor genes that negatively regulate mTOR, such as PTEN, AMPK, LKB1, and TSC1/2 stimulate autophagy while, conversely, oncogenes that activate mTOR, such as class I PI3K, Ras, Rheb, and AKT, inhibit autophagy, suggesting that autophagy is a tumor suppressor mechanism.
