The somatic mutation theory of aging, put forth over 30 years ago, was originally based on the observation that exposure to ionizing radiation could induce an "aged" phenotype and reduce lifespans in experimental animals. According to this theory, the age-related accumulation of genetic mutations ...
Mutation accumulation in somatic cells contributes to cancer development and is proposed as a cause of aging. DNA polymerases Pol ε and Pol δ replicate DNA during cell division. However, in some cancers, defective proofreading due to acquiredPOLE/POLD1exonuclease domain mutations causes marked...
The mutation theory of aging has not had serious experimental confirmation. There is some evidence that there is no significant accumulation of mutations with age in the nondividing neurons of the brain in mice. View chapter Chapter Autoantibodies Against Cytokines The Autoimmune Diseases (Fifth ...
The somatic mutation theory of aging posits that the accumulation of mutations in the genetic material of somatic cells as a function of time results in a decrease in cellular function. In particular, the accumulation of random mutations may inactivate genes that are important for the functioning ...
Single-cell whole genome sequencing (WGS) is expected to provide comprehensive assessments of somatic mutations [5]. 2.2. Ageing and somatic mutations Modern ageing theories can be categorized into two schools of thought: programmed and error theories [25].‘The somatic mutation theory’ or somatic...
The rates and patterns of somatic mutation in normal tissues are largely unknown outside of humans1–7. Comparative analyses can shed light on the diversity of mutagenesis across species, and on long-standing hypotheses about the evolution of somatic mut
The meaning of SOMATIC is of, relating to, or affecting the body especially as distinguished from the germplasm. How to use somatic in a sentence.
Single-Neuron Sequencing Analysis of L1 Retrotransposition and Somatic Mutation in the Human Brain - ScienceDirect Whole-genome sequencing of individual neurons from human brain shows that retrotransposition of the L1 element is infrequent. L1 insertions may thus genera... G Evrony,X Cai,E Lee,....

Somatic mtDNA mutation spectra in the aging human putamen.doi:10.1371/journal.pgen.1003990The accumulation of heteroplasmic mitochondrial DNA (mtDNA) deletions and single nucleotide variants (SNVs) is a well-accepted facet of the biology of aging, yet comprehensive mutation spectra have not been ...
