The Department of Biochemistry and Molecular Biology is dedicated to the education of medical and graduate students in biochemistry, molecular biology and nutrition. Researchers in our highly interactive department utilize cutting-edge techniques to discover the molecular basis of disease, including research focused on cancer, infectious disease and aging.

Biochemistry research at the College of Medicine is in part driven by analytical technologies and instrumentation, such as protein production and purification, spectroscopy, structure analysis, mass spectrometry, and biosensor-based protein-protein interaction analysis. Molecular and cell biology are major experimental approaches complementing biochemistry and enable the elucidation of cellular processes at the biochemical level related to human disease.

The department consists of 12 faculty, including 2 full-time educators and 10 independent laboratory heads, with externally funded programs. Our outstanding faculty and their exceptional teams of research scientists, postdoctoral scholars, graduate students and undergraduate researchers are key to our success. The collaborative nature of the department and the wide array of scientific approaches, from structural biology and biophysical methods, to cell biology and animal studies, contribute to the exciting research environment.

Our department has a long history of outstanding educational programs for both PhD and MS candidates. Our graduate programs include:

Our research-intensive graduate programs offer high quality mentored research experiences. These train our students to be successful scientists and independent thinkers, prepared for a variety of careers. Students from our programs hold careers in a range of scientific areas including academic and industry research, teaching roles, government positions and science writing and policy.

We continue to expand the department by hiring additional faculty with interests in new areas of biochemistry and molecular biology, afforded by the rapid expansion of technical capabilities and new discoveries in basic biology.

Research at the Department of Biochemistry & Molecular Biology

Our major disease focus has been on cancer. Cancer is a multifaceted disease and basic biochemical/molecular research on a broad range of cellular processes has been extremely powerful in understanding cancer biology—from transformation, to metastasis, to response, to treatment. Cancer biology is a "big tent" under which many disparate areas of inquiry can be united and focused.

The cancer biology research program emphasizes:

  • Control of cell proliferation (Bouchard, Noguchi, Reginato)
  • Signal transduction (Bouchard, Noguchi, Reginato)
  • DNA replication and repair (Berkowitz, Noguchi)
  • Cancer metabolism (Reginato, Bouchard)
  • Metastasis (Reginato)
  • Computational biology (Somarowthu)
  • Transcription and epigenetics (Bouchard, Reginato, Noguchi, Sell, Somarowthu)
  • Apoptosis (Bouchard, Reginato, Noguchi)
  • Aging (Noguchi, Sell)
  • Viral carcingogenesis (Bouchard)

A second research theme is directed toward understanding structure-function relationships in biological macromolecules. This includes studies of:

  • Membrane proteins (Loll, Chaiken)
  • Cytoskeleton and signal integration (Padrick)
  • Receptor-ligand interactions (Chaiken, Loll)
  • Enzymology and drug design (Loll, Chaiken)
  • Post-translational protein modifications (Bouchard, Noguchi, Reginato, Strochlic)
  • Molecular-level studies of specific diseases, including:
    • HIV and hepatitis (Chaiken, Abrams, Bouchard)
    • Malaria (Vaidya)
    • Sepsis (Loll)
    • Neurodegenerative disease (Loll, Saunders)
    • Aging (Noguchi, Sell)
    • Infertility and developmental defects (Berkowitz, Strochlich)

Another initiative arising from this approach is in the development of small molecule inhibitors (Loll, Chaiken, Reginato), including development of new antibiotics (Loll).

Meet Our Faculty – Eishi Noguchi, PhD

"I am interested in DNA damage response. One example of DNA damage is when you go outside, you are exposed to ultraviolet rays (UV). You might enjoy the sunshine but the UV cuts your DNA. When you drink alcohol, it converts into something very toxic that also cuts your DNA. That is acetaldehyde, which also causes hangovers. I'm interested in how our bodies fix that kind of DNA damage..."
