TLDR
Large-scale linkage studies of long-lived families, longitudinal candidate-gene association studies and the development of analytical methods provide the potential for future progress in human studies of longevity.Abstract:
Twin studies show that genetic differences account for about a quarter of the variance in adult human lifespan. Common polymorphisms that have a modest effect on lifespan have been identified in one gene, APOE, providing hope that other genetic determinants can be uncovered. However, although variants with substantial beneficial effects have been proposed to exist and several candidates have been put forward, their effects have yet to be confirmed. Human studies of longevity face numerous theoretical and logistical challenges, as the determinants of lifespan are extraordinarily complex. However, large-scale linkage studies of long-lived families, longitudinal candidate-gene association studies and the development of analytical methods provide the potential for future progress.read more

Inflammaging and anti-inflammaging: A systemic perspective on aging and longevity emerged from studies in humans
Claudio Franceschi,Miriam Capri,Daniela Monti,Sergio Giunta,Fabiola Olivieri,Federica Sevini,Maria Panagiota Panourgia,Laura Invidia,Laura Celani,Maria Scurti,Elisa Cevenini,Gastone Castellani,Stefano Salvioli +12 more
TL;DR: It is proposed that inflammaging can be flanked by anti-inflammaging as major determinants not only of immunosenescence but eventually of global aging and longevity.

Biodemography of human ageing.
TL;DR: Research by demographers, epidemiologists and other biomedical researchers suggests that further progress is likely to be made in advancing the frontier of survival — and healthy survival — to even greater ages.

TL;DR: Long-lived men presented several additional phenotypes linked to healthy aging, including lower prevalence of cancer and cardiovascular disease, better self-reported health, and high physical and cognitive function, despite significantly older ages than controls, several of these aging phenotypes were associated with FOXO3A genotype.

Association of FOXO3A variation with human longevity confirmed in German centenarians

TL;DR: This study investigated 16 known FOXO3A SNPs in an extensive collection of 1,762 German centenarians/nonagenarians and younger controls and provided evidence that polymorphisms in this gene were indeed associated with the ability to attain exceptional old age, and confirmed the initial discovery in the Japanese sample.
Journal ArticleDOI
Long live FOXO: unraveling the role of FOXO proteins in aging and longevity
TL;DR: The mechanisms by which FOXO factors contribute to longevity will be discussed in diverse animal models, from Hydra to mammals, and compelling evidence of FOXOs as contributors for extreme longevity and health span in humans will be addressed.

Interleukin-6 −174G/C polymorphism and longevity: a follow-up study
TL;DR: The mortality data of the cohort of 285 nonagenarians (representing mortality between 90 and 95 years of age) and correlated these to the IL-6 genotype showed the frequency of -174 allele G was clearly higher in the survivors than in the non-survivors.

TL;DR: Overall, the more genetically homogenous Ashkenazi ethnic group showed evidence for association in five genes examined suggesting that future studies in this population would gainfully focus on this ethnic group.

Paraoxonase 1 polymorphisms and survival

TL;DR: Investigating the impact of the PON 192Q/R polymorphism on susceptibility to CHD indicates that PON1 192RR homozygosity is associated with increased mortality in women in the second half of life and that this increased mortality is possibly related toCHD severity and survival after CHD rather than susceptibility to development of CHD.

Genome-Wide Scan for a Healthy Aging Phenotype Provides Support for a Locus Near D4S1564 Promoting Healthy Aging
TL;DR: The authors' results provide independent evidence that a locus on the long arm of chromosome 4 is associated with better physical aging and/or longevity, and previously linked to extreme longevity segregation as an autosomal dominant trait in centenarian families.
