Uncovering genes and small molecules that prolong lifespan through enhanced molecular stability.

Lab focus

During aging, many biological processes go out of balance. Changes are apparent at the level of the whole animal, tissues, cells, molecules, and metabolism. We believe that changes at the molecular level drive the changes at higher levels. Animals have extensive endogenous mechanisms that maintain balance (homeostasis) in young animals. These homeostatic mechanisms degrade with age. We believe that we can prevent this degradation and re-engage these maintenance systems in older animals, which will prevent disease and extend lifespan.

The Lithgow lab concentrates on identifying small drug-like molecules that re-engage and enhance homeostatic mechanisms in the microscopic nematode worm C. elegans. We aim to boost mechanisms that prevent protein misfolding and remove damaged proteins and other forms of molecular damage. Frequently, treatment with such molecules results in lifespan extension and postpones disease pathology. We now collaborate with other Buck researchers to test the effectiveness of these compounds to prevent chronic disease in mouse models.

Why it matters

Aging mechanisms are novel targets for both proliferative diseases such as cancer and degenerative diseases such as Alzheimer’s. The characterization of normal aging mechanisms is vital for the development of new therapeutic avenues for these devastating conditions. Aging mechanisms discovered in the worm model are very likely to be important in humans as well and may influence drug discovery. We also believe that demonstrating the effectiveness and mechanisms of non-drug interventions like nutrients and diet may provide information for people to make lifestyle choices to help them live better longer.

One theme continues to emerge from our work – that aging and disease stem from common mechanisms. Delaying disease by delaying the aging process is a real proposition.

  • David Hall  Research Associate

    After completing his degree in molecular, cell and developmental biology at the University of California, Santa Cruz, David came to the Buck in June 2014 out of an interest in gerontology, where he joined the Kapahi lab. There, for several years he worked on a combination of C. elegans-based assays, compound library screens and mass spectrometry experiments for several projects, including studies of advanced glycation end products (AGEs), connections between circadian clocks and dietary restriction, and the kidney disease cystinuria. At the same time there, he was also introduced to and involved in the CITP project in collaboration with Lithgow Lab, where he contributed to the setup and operation of the CITP's Automated Lifespan Machine (ALM) network, and also developed new methods and assay applications for it which became adapted for use project-wide. The CITP grew to become a greater and greater focus of David's work, to where he is now the project coordinator for Lithgow Lab's CITP effort. In this role, he works closely with collaborating labs and the Lithgow CITP members in the planning, setup, acquisition and analysis of data for the project, as well as troubleshooting and maintenance for the ALM network. In the CITP, the main objective is to discover robust, highly-reproducible healthspan and lifespan benefits derived from drug treatment regimens across three distinct Caenorhabditis species, which in turn are also composed of several strains of highly diverse genetic backgrounds.
