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.

  • Edward Anderton  PhD Candidate, USC-Buck Biology of Aging Program

    Edward Anderton is a 2nd year PhD student in the USC-Buck Biology of Aging Program in the Lithgow lab. Originally from Yorkshire in the United Kingdom, Edward received his integrated bachelors-master’s degree in biochemistry from the University of Oxford. His thesis project focused on differential expression of Hox genes in the evolution of the mammalian brain. After graduating, he worked in project management for the UK’s largest retail bank for three years before returning to his real passion - science and solving aging. He is particularly interested in how declining mitochondrial function and quality control drives aging phenotypes. When he isn't buried in papers he likes to climb cliffs and boulders, travel to distant countries and explore the great outdoors.

  • Manish Chamoli, PhD  Research Scientist, Larry L. Hillblom Fellow

    Dr. Chamoli earned his PhD in aging biology in June 2015 from the National Institute of Immunology in India after completing a five-year integrated master’s in biotechnology. His PhD work was focused on understanding molecular pathways mediating dietary restriction–induced longevity using C. elegans as a model organism. His research was supported by a fellowship from the Indian government’s Department of Biotechnology. Manish joined the Lithgow lab as a postdoctoral fellow in February 2015. He is now working in collaboration with the Andersen lab to utilize novel pharmacological agents to understand the role of autophagic processes in aging and age-related neurodegeneration. His current work is supported by a three-year postdoctoral fellowship from the Larry L. Hillblom Foundation.

  • Anna Foulger  Research Associate

    Anna joined the Buck in 2014 and is a Research Associate in the Lithgow Lab working on several different projects. She is currently working with Suzanne Angeli researching the questions of mitochondrial dysfunction in age with C. elegans and mammalian cells, as well as working with Renuka Sivapatham on studying therapies for Alzheimer’s Disease in mice. Anna also assists with various projects with Dipa Bhaumik and occasionally with the Caenorhabditis Intervention Testing Program (CITP), which is focused on testing robust compounds that extend the lifespan and healthspan in worms. Additionally, she is on several publications with more to come. Anna graduated Magna Cumme Laude from San Francisco State University with a Bachelors Degree in zoology in 2018. In addition to her scientific work, Anna has years of experience in the animal care field and volunteers with animals whenever she can.

  • 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.
