## Abstract

The overarching goal of this Program Project Grant (PPG), “Comparative Genomics of Longevity and
Alzheimer’s disease” is to identify mechanisms responsible for health and longevity, with the focus on
genome/epigenome stability and Alzheimer’s disease (AD) and related dementias (ADRD), in long-lived
mammalian species. Mammals differ over 100-fold in their maximum lifespans, from 2 years in a shrew to over
200 years in the bowhead whale. Characterization of the processes responsible for this disparity in lifespan will
enable the development of interventions to prevent or cure age-related diseases including AD and ADRD. The
central hypothesis of this PPG is that long-lived species have evolved more efficient mechanisms to
maintain genome/epigenome stability and prevent Alzheimer’s and ADRD, which can be adapted to
extend human healthspan. In the previous phase of the PPG, we generated exciting data that support our
hypothesis. Specifically, we identified DNA double strand break repair as a mechanism that strongly correlates
with longevity; improved DNA repair in mouse cells by specific amino acid changes; showed that the naked mole
rat hyaluronan synthase 2 gene improves mouse health and lifespan and delays ADRD pathology; showed that
mutation rates are lower in long-lived species; developed epigenetic clocks for naked mole rats; discovered
mechanisms responsible for longevity and genome stability in the longest-lived mammal, the bowhead whale;
identified omics profiles of long-lived species; identified a potential mechanism for sporadic AD in degu; and
generated new mouse models with genes from long-lived mammals. In the next cycle we will expand our studies
to developing interventions and applying novel omics techniques. This PPG is comprised of four integrated
projects and three cores. Project 1 (Gorbunova; Garcia) is focused on mechanisms responsible for more efficient
genome/epigenome stability and developing anti-aging and AD and ADRD interventions. Project 2 (Seluanov;
O’Banion) develops novel animal models of AD resilience (naked mole rat) and sporadic AD (degu). Project 3
(Vijg; Fang) investigates mutations and epimutations in animals with diverse lifespans and in AD models using
novel, high throughput single-molecule approaches. Project 4 (Gladyshev; Tyshkovskii) uses multi-omics to
identify genes and pathways involved in genome/epigenome stability across species and developing aging,
longevity and AD biomarkers. The research team consists of investigators dedicated to longevity research who
are experts in comparative biology and DNA repair (Gorbunova), long-lived rodents (Seluanov), AD and ADRD
(O’Banion), mutagenesis and single-cell approaches (Vijg), comparative genomics and biomarkers (Gladyshev;
Tyshkovskiy); cutting-edge omics techniques, proteomics, and mass spectrometry (Garcia); long-read
sequencing (Fang) and bioinformatics (Zhang, Core C). Moreover, we developed a collection of primary cells
and tissues, and animal colonies, to ...
