Aird Lab

Department of Cellular & Molecular Physiology

Penn State College of Medicine (Hershey, PA)

Multiple positions open for postdoctoral fellows interested in metabolism.

See “Positions” tab for details.

 

The Aird lab focuses on:

  1. The mechanisms and pathological implications of cellular senescence.  Cellular senescence is a stable cell cycle arrest that is a tumor suppression mechanism and also plays a role in age-related pathologies.  In particular, her lab is interested in the intersection between cellular senescence and metabolism.  Understanding the mechanisms of how cells undergo and overcome this proliferative arrest may lead to novel therapeutic strategies for both cancer and aging. These projects aim to: 1) understand the earliest events in tumorigenesis; 2) identify novel crosstalk mechanisms between metabolism and epigenetics that underly both the cell cycle arrest and senescence-associated secretory phenotype (SASP); and 3) exploit senescence pathways as novel therapeutic strategies for cancer

  2. Metabolic reprogramming in ovarian cancer.  Very little is understood about the metabolic programming of normal Fallopian tube and how these pathways go awry in ovarian cancer.  These projects aim to: 1) characterize metabolism in normal Fallopian tube, primary ovarian cancer tumors, tumors within the ascites fluid, and metastatic sites; and 2) use this information to exploit metabolic vulnerabilities as novel ovarian cancer therapies.

  3. Nucleotide metabolism. Homeostasis of nucleotide metabolism is critical for the health of cells. We are interested in understanding novel pathways that regulate nucleotide metabolism and whether nucleotide biosynthesis is a metabolic vulnerability for some cancer cells. These projects aim to understand: 1) the interplay between the cell cycle and nucleotide metabolism; 2) ATR-mTORC1-mediated nucleotide metabolism in cancer cells with low p16; and 3) the cross-talk between nucleotide metabolism and the tumor microenvironment.

The Aird lab is currently funded by an R00 and F31 from the NIH/NCI, a Pilot Award from the Department of Defense Ovarian Cancer Research Program, an award from the Sandy Rollman Ovarian Cancer Foundation, and the Penn State Cancer Institute. Previous funders include the W. W. Smith Charitable Trust.
