Leveraging Proteostasis Mechanisms to Promote Healthy Aging

The Bennett Lab studies the fundamental principles of how cells build, maintain, and destroy proteins. Our research aims to define mechanisms that can be leveraged to promote healthy aging and combat human aging-associated disorders.

About The Bennett Lab

The Bennett research group aims to identify pathways and cellular factors that can be targeted to predictably impact proteostasis function to both exacerbate and diminish steady-state and stress-induced proteostasis capacity.
The research group utilizes integrated molecular, genetic, and systems-level approaches to examine mechanisms that catalyze proteome remodeling. We employ global and quantitative proteomic platforms that enable systematic analyses of protein homeostasis. These platforms enable studies aimed at detailing how the proteome responds to both genetic and environmental challenges to proteostasis.

Research Directions

Proteostasis Regulation

Understanding how cells regulate the synthesis, folding, and degradation of proteins to maintain cellular health.

Cellular Stress Responses

Exploring how cells respond to stress conditions to alter cellular stress resilience.

Proteostasis Network and Aging

We apply global and molecular approaches to manipulate the proteostasis network to improve tissue function during aging.

Ubiquitin Biology

Identifying and characterizing ubiquitin-dependent mechanisms that regulate cellular quality control pathways

A collaborative study with the Goldrath Lab investigating T-cell proteostasis is published
  • Fun collaboration with our favorite T-cell experts. Nicole’s tour de force establishes that terminally exhausted tumor-infiltrating lymphocytes have reduced expression of three key ubiquitin ligases and signatures of proteostasis dysfunction.
  • Xuezhen and Fulin spearheaded some truly stunning deep proteomics from in vivo isolated T-cell populations. Congrats to everyone involved.
Xuezhen's HUWE1 study is published

Congrats to team HUWE1 for this impressive and comprehensive study. It sets the standard for defining ubiquitin ligase substrates using rapid proteomic profiling.

Collaborative study with the Lykke-Andersen lab selected for prize in RNA Journal
  • Congrats to Tim and all the authors that participated in this study.
