The Ability of Glyphosate to Impair Metabolic Homeostasis Via the Gut Microbiome and Metabolites
Funding Agency: National Institute of Allergy Environmental Health Sciences
Funding Amount: $1,838,500
Project Objective: Increased rates of obesity and diabetes parallels the increased pesticide usage in the United States, especially the use of glyphosate, but to date no study has comprehensively examined the impact of glyphosate exposure on the development of obesity and diabetes. The current work will determine if glyphosate impairs metabolic homeostasis, and if this is due to changes in the gut microbiota and bacterially-derived metabolites, like bile acids. These studies will help understand the impact of environmental exposures on host metabolism and could lead to more targeted therapeutic approaches to treat metabolic disease.

The role of asymmetric protein dimethylation during the human papillomavirus lifecycle
Funding Agency: National Institute of Allergy and Infectious Disease
Funding Amount: $1,901,557
Project Objective: Persistent infection with human papillomaviruses (HPVs) is the primary risk factor for cervical cancer development. Yet, the mechanisms that HPVs use to optimize the cellular environment and establish a persistent infection are not understood. These studies will remove this knowledge gap by providing mechanistic insights into how these viruses establish persistent infections and furthering our understanding of potential therapeutic targets for HPV-cancers.
Interplay of the cGAS/STING Immune Pathway and Oncogenic Papillomaviruses
Funding Agency: American Cancer Society
Funding Amount: $792,000
Project Objective: Human papilloma viruses (HPVs) cause persistent infections that are responsible for an estimated 5% of cancers worldwide. The mechanisms through which these viruses cause persistent infections are currently unknown. These studies will establish the role of the anti-viral response pathway known as cGAS/STING on the ability of HPVs to overcome cellular defenses and establish persistent infections that lead to cancer.

Role of the hepatic GABA shunt in insulin resistance and hyperinsulinemia
Funding Agency: National Institutes of Health
Funding Amount: $1,918,750
Co-Investigator: Frank Duca, ACBS
Project Objective: The severity and incidence of type 2 diabetes is positively related to liver fat concentration. As fat accumulates in the liver, the liver produces and releases more GABA, an inhibitory neurotransmitter. This project aims to understand how liver GABA production and release, can be manipulated to affect insulin sensitivity.
Pre-clinical tests of novel GABA transaminase inhibitors to treat obesity induced hyperglycemia, hyperinsulinemia, and insulin resistance
Funding Amount: $100,000
Co-Investigator: May Khanna, New York University
Project Objective: Liver GABA production is catalyzed by GABA transaminase and is positively associated with the severity of insulin resistance and elevations in blood insulin concentration. GABA transaminase inhibition or knockdown improves insulin sensitivity and lowers serum insulin. Available GABA transaminase inhibitors were developed to treat epilepsy and cross into the brain resulting in unacceptable side effects for a medication to treat diabetes. From 14 lead molecules, we aim to optimize novel GABA transaminase inhibitors with improved efficacy and specificity, and limited blood brain barrier penetrance.
