The evolution of aging and lifespan
Trends Genet. 2023 Sep 14:S0168-9525(23)00186-5. doi: 10.1016/j.tig.2023.08.005. Online ahead of print.ABSTRACTAging is a nearly inescapable trait among organisms yet lifespan varies tremendously across different species and spans several orders of magnitude in vertebrates alone. This vast phenotypic diversity is driven by distinct evolutionary trajectories and tradeoffs that are reflected in patterns of diversification and constraint in organismal genomes. Age-specific impacts of selection also shape allele frequencies in populations, thus impacting disease susceptibility and environment-specific mortality risk. Further, ...

Whole-genome doubling in tissues and tumors
Trends Genet. 2023 Sep 13:S0168-9525(23)00187-7. doi: 10.1016/j.tig.2023.08.004. Online ahead of print.ABSTRACTThe overwhelming majority of proliferating somatic human cells are diploid, and this genomic state is typically maintained across successive cell divisions. However, failures in cell division can induce a whole-genome doubling (WGD) event, in which diploid cells transition to a tetraploid state. While some WGDs are developmentally programmed to produce nonproliferative tetraploid cells with specific cellular functions, unscheduled WGDs can be catastrophic: erroneously arising tetraploid cells are ill-equipped to c...

The searchable chromosome

Online ahead of print.ABSTRACTTo date, genome structure and dynamics have been studied mostly independently; their interplay is a notable blind spot of the field. Brückner, Chen, et al. recently demonstrated an integrated experimental approach sensitive to both, uncovering a striking robustness of enhancer-promoter search times (dynamics) to changes in genomic separation (structure).PMID:37690888 | DOI:10.1016/j.tig.2023.08.006 (Source: Trends in Genetics : TIG)

Dynamics of the Streptomyces chromosome: chance and necessity
Trends Genet. 2023 Sep 5:S0168-9525(23)00166-X. doi: 10.1016/j.tig.2023.07.008. Online ahead of print.ABSTRACTStreptomyces are prolific producers of specialized metabolites with applications in medicine and agriculture. Remarkably, these bacteria possess a large linear chromosome that is genetically compartmentalized: core genes are grouped in the central part, while the ends are populated by poorly conserved genes including antibiotic biosynthetic gene clusters. The genome is highly unstable and exhibits distinct evolutionary rates along the chromosome. Recent chromosome conformation capture (3C) and comparative genomics ...
