Research Overview

Research Interests

Genome maintenance mechanisms relevant to the biology of cancer and aging, including DNA replication, DNA repair, DNA damage response and cell cycle checkpoints; investigating the mechanisms required for preservation of genomic integrity in response to environmental factors and toxins, including alcohol and aldehydes


Research Program: Genome Maintenance Mechanisms

Genomic instability is a hallmark of cancers and age-related diseases. Our long-term goal is to understand how cells maintain genomic integrity to regulate lifespan and avoid tumorigenesis. Emerging evidence suggests that a variety of environmental factors and toxins damage DNA, leading to an arrest of the DNA replication fork, the actual site of DNA synthesis. Arrested replication forks are prone to collapse, posing serious threats to genomic integrity, suggesting that DNA replication problems are critical drivers of genomic instability that promotes aging and tumorigenesis.

The Noguchi lab works with mammalian cells and fission yeast (Schizosaccharomyces pombe). Fission yeast is an exceptional model system for studying cell cycle control and genome maintenance mechanisms that are highly conserved amongst most eukaryotes, including humans. Our general approach defines principles and identifies important proteins in fission yeast and then determines whether human homologues of these proteins have related function using mammalian cell culture. 

Current Research Projects

  • Identify and investigate the mechanisms of DNA replication at difficult-to-replicate chromosomal regions. There are numerous chromosomal regions that are prone to DNA damage. These regions are difficult to replicate, and are often associated with repetitive DNA sequences and high rates of transcription. We investigate the mechanisms that prevent genomic instability at these difficult-to-replicate regions, including telomeres and highly transcribed regions.
  • Investigate the mechanisms of alcohol-mediated esophageal carcinogenesis. Alcohol consumption is a major cause of esophageal cancer. We investigate the role of acetaldehyde, the primary metabolite of alcohol, in genomic instability and esophageal cancer development. We also investigate DNA repair mechanisms that are responsible for the repair of alcohol/acetaldehyde-mediated DNA damage.
  • Investigate the genetic mechanisms that govern lifespan extension by preserving genomic integrity. Aging begins at the molecular level: accumulation of damaged cellular constituents leads to cell dysfunction or cell senescence. Such damage also occurs on chromosomal DNA, leading to genomic instability. Therefore, our goal is to understand how cells maintain genomic integrity to regulate lifespan. We are also interested in the role of the TOR pathway in lifespan regulation under calorie-restricted conditions.  

Environmental factors or even our metabolism can cause DNA damage during DNA replication, leading to genomic instability, which is a hallmark of cancer and aging. Therefore, our research projects will provide a framework for guiding investigations that will greatly impact the biology of cancer and aging.
