Worms

C. elegans provide a simple, genetically tractable whole animal model for determining how changing the levels of a metabolite like SAM can affect cells or change physiological parameters such as lipid accumulation or aging.

Human Cells

We use human cell lines to test our models in a more complex environment and determine initial relevance to human biology.

Mice

Mice provides a whole animal system to model effects of changing methylation on mammalian physiology

About

Walker lab;
Program in Molecular Medicine
UMASS Medical School
Worcester, MA

The Walker lab is part of the Program in Molecular Medicine at UMASS Medical School. PMM has labs working on metabolism, structural biology, virology, neurobiology and development on organisms from yeast to humans. We have a bi-weekely post-doc seminar series (Confabs), a student presentation series (IGP). Within UMASS, we particiapte in MetNet, a monthly metabolism-centered seminar series with talks from UMASS labs as well as outside speakers. We also attend yearly C. elegans meetings.

Our Projects

We study how changing the level of the metabolite S-adenosylmethionine alters methylation patterns changing stress-responses, aging and lipid accumulation

Amy K Walker

PI

Still at the bench with various projects in the lab, learning some code. Outside of lab, I experiment in the kitchen, garden and puzzle-person.

Adwait Godbole

Postdoc

Hi, I am a postdoc in the Walker lab where I am interested in understanding how S-adenosyl methionine levels influence the transcriptional response to environmental stress conditions. Specifically I am interested in understanding the cellular role of the SAM synthases. I picked up my worm skills in a previous life in The Scripps Research Institute in Florida where I worked on a project that involved understanding the mechanism of action of age modulating compounds. If I am not in the lab, you might find me enjoying (?) a run on the Charles River Esplanade or rooting around in an antique/vintage shop.

Christofer Welsh

Graduate Student: Mello Scholar 2019

I am interested in exploring the role of metabolic signaling in regulation of the expression of genes that facilitate cellular homeostasis. My project involves investigating how intracellular trafficking is regulated to stabilize the Golgi apparatus during membrane stress due to abnormal lipid homeostasis. I enjoy listening to music while picking my worms. In my spare time I like playing games, reading, or cooking (and eating) different kinds of food!
