  Is metabolism involved in pancreatic carcinogenesis?
  Can we target metabolism to prevent pancreatic cancer?

  Pancreatic cancer is the deadliest among the most common types of human malignancies. In light of the limited effectiveness of the current therapeutic options, substantial benefits could be gained by improving our understanding of the factors that contribute to tumor onset, particularly for patients at elevated risk, with the hope of curtailing disease incidence and enhancing the opportunity to treat it early.

  Impaired metabolism is a hallmark of cancer. In the lab, we study how altered metabolism contributes to cell transformation and disease initiation. We are interested in whether pharmacological or dietary interventions can impact the susceptibility to develop pancreatic cancer.

  Pancreatic cancer is characterized by poor overall survival and few efficacious therapeutic interventions. One area that has offered significant scope for further exploration are the numerous metabolic disturbances in preclinical models of pancreatic cancer.

  Given the relative hypoxia of the tumor microenvironment and the limited nutrient availability, pancreatic tumor cells undergo substantial metabolic rewiring. Several of these derangements lead to imbalances in metabolites, including S-adenosylmethionine (SAM), α-ketoglutarate (αKG), and acetyl-CoA that are crucial to the regulation of epigenetic landscapes. They are substrate (SAM, acetyl-CoA) or substrates (αKG) for enzymes that modify chromatin conformation and regulate gene expression. In particular, we demonstrated that the availability of acetyl-CoA influences histone acetyl-transferase (HATs) activity, dictates global levels of histone acetylation.

  Of note, oncogenes actively reprogram both cell metabolism and epigenetics. Previously, we have demonstrated that pancreatic cancer initiation features abundant epigenetic reprogramming in the progression to neoplasia, and that the cytoplasmic enzyme ATP-citrate lyase (ACLY), which produces acetyl-CoA from citrate, is essential to the neoplastic process. In mouse models, Acly deletion diminishes the enhancement of histone acetylation that occurs in response to mutant KRAS.

  

  The role of mitochondrial for the generation of acetyl-CoA, and the downstream effects of mutant KRAS-induced acetyl-CoA on chromatin landscapes remain unknown.

  Our long-term goals are to identify how metabolic rewiring impacts the epigenome to facilitate alterations to cell fate in cancer. We intend to utilize acetyl-CoA to define the mitochondrial-to-nuclear connections that control epigenetic reprogramming in pancreatic cancer initiation. Our aims are to elucidate (1) the mechanisms by which mitochondrial function controls the availability of exported citrate and nucleo-cytoplasmic acetyl-CoA, and (2) the global effect of alterations in acetyl-CoA abundance on the epigenome and preneoplastic cell fate.

  We utilize acinar explants in vitro and lineage-traced mouse models of acinar-derived neoplasia to interrogate the chromatin accessibility and histone acetylation dynamics induced by alterations to acetyl-CoA.

  Mitochondria are key effectors of KRAS-triggered tumorigenesis. We study whether environmental factors impact mitochondrial structure or function and whether this increases the risk for pancreatic cancer later in life.
