The evolution of longevity [PDF]

open access: yesCurrent Biology, 2002
According to the evolutionary theory of ageing, genes will not evolve for the purpose of promoting ageing. Moreover, the mutation–accumulation theory predicts that mutations in different genes will cause ageing in different evolutionary lineages. However, as discussed, empirical evidence does not generally support mutation–accumulation as a mechanism ...

Mitochondrial TrxR2 regulates metabolism and protects from metabolic disease through enhanced TCA and ETC function

open access: yesCommunications Biology, 2022
TrxR2 overexpression in mice enhances metabolism and prevents high-fat diet induced metabolic deficits in mice through alteration in function of several enzymes in the tricarboxylic acid cycle and complexes of the electron transport chain.

Ironing out exercise on immuno-oncological outcomes

open access: yesJournal for ImmunoTherapy of Cancer, 2022
Despite accumulating evidence that supports the beneficial effects of physical exercise in inhibiting cancer progression, whether exercise modulates its effects through systemic and cellular changes in iron metabolism and immune-tumor crosstalk is ...

The Longevity of Sirtuins

open access: yesCell Reports, 2012
Controversy has recently arisen over the role of sirtuins in metazoan aging. In this issue of Cell Reports, Banerjee et al. demonstrate that Drosophila Sir2 is necessary for life span extension in response to dietary restriction and that its overexpression in the fat body increases the life span.

Correlates of estimated lifetime cruciate ligament survival inform potential rupture risk reduction strategies: findings from the Exceptional Aging in Rottweilers Study

open access: yesScientific Reports, 2023
Cranial cruciate ligament (CCL) rupture is one of the most commonly diagnosed orthopedic conditions of pet dogs, making estimated lifetime cruciate ligament survival an attractive endpoint for studies attempting to define clinical and genetic correlates ...

Utilization of defined microbial communities enables effective evaluation of meta-genomic assemblies

open access: yesBMC Genomics, 2017
Background Metagenomics is the study of the microbial genomes isolated from communities found on our bodies or in our environment. By correctly determining the relation between human health and the human associated microbial communities, novel mechanisms

A large‐scale retrospective study in metastatic breast cancer patients using circulating tumour DNA and machine learning to predict treatment outcome and progression‐free survival

open access: yesMolecular Oncology, EarlyView.
There is an unmet need in metastatic breast cancer patients to monitor therapy response in real time. In this study, we show how a noninvasive and affordable strategy based on sequencing of plasma samples with longitudinal tracking of tumour fraction paired with a statistical model provides valuable information on treatment response in advance of the ...
