How aneuploidy affects metabolic control and causes cancer.
The complexity and diversity of cancer-specific phenotypes, including de-differentiation, invasiveness, metastasis, abnormal morphology and metabolism, genetic instability and progression to malignancy, have so far eluded explanation by a simple, coherent hypothesis. However, an adaptation of Metabolic Control Analysis supports the 100-year-old hypothesis that aneuploidy, an abnormal number of ...
متن کاملMutational inactivation of STAG2 causes aneuploidy in human cancer.
Most cancer cells are characterized by aneuploidy, an abnormal number of chromosomes. We have identified a clue to the mechanistic origins of aneuploidy through integrative genomic analyses of human tumors. A diverse range of tumor types were found to harbor deletions or inactivating mutations of STAG2, a gene encoding a subunit of the cohesin complex, which regulates the separation of sister c...
متن کاملHow aneuploidy may cause cancer and genetic instability.
It has been difficult to find a common cause for the many and complex phenotypes of cancer such as dedifferentiation, invasiveness, abnormal morphology, growth rate and metabolism, genetic instability, progression to malignancy, cellular heterogeneity of phenotypes and karyotypes, and clonal origin despite heterogeneity. Over 100 years ago aneuploidy, an abnormal balance of chromosomes, was pro...
متن کاملAneuploidy Causes Non-genetic Individuality
Phenotypic variability is a hallmark of diseases involving chromosome gains and losses, such as Down syndrome and cancer. Allelic variances have been thought to be the sole cause of this heterogeneity. Here, we systematically examine the consequences of gaining and losing single or multiple chromosomes to show that the aneuploid state causes non-genetic phenotypic variability. Yeast cell popula...
متن کاملHow the Nonextensivity Parameter Affects Energy Fluctuations
In this article, the effect of the nonextensivity parameter on the energy fluctuations of nonextensive systems is studied in two different versions of the Tsallis statistical mechanics. Once a general expression has been reported for the energy fluctuations in the second version (Tsallis work in 1988), the energy fluctuations of an ideal gas and a harmonic oscillator are studied in the second a...
