PARP1 and PARylation as Novel Effectors of Gut Inflammation
Major Goals: Inflammatory bowel diseases (IBD) are complex, multifactorial disorders characterized by impaired host- microbiome interactions that lead to chronic and relapsing intestinal inflammation with incompletely understood etiology For the first time, we demonstrate that poly-ADP-ribosylation (PARylation), a post-translational protein modification known to profoundly affect cellular functions in other systems, plays active role in the gut epithelial cell biology, host-microbiome interactions, and mucosal inflammatory responses. We seek to determine the interplay between commensal microbiota and mucosal PARylation, work that may lead to novel approaches to IBD care.

Title: Reprogramming the Pancreatic Tumor Microenvironment to Increase Efficacy of Targeted
Therapies
Major Goals: The proposed research has relevance to public health because Pancreatic Ductal Adenocarcinoma (PDAC) is one of the most lethal malignancies with an approximate 8% 5-year survival rate despite therapy. The lack of an effective response of PDAC to various existing treatments contributes to poor prognosis, and makes this disease an unmet medical challenge. The proposed studies will use patient-derived advanced preclinical models of PDAC and combinatorial therapeutic strategies to increase the efficacy of treatment for each individual patient that will subsequently improve survival and outcome.

of GI Cancers
Role: Zavros (PI)
Sparking bench-to-bedside Team Science Award, University of Arizona Cancer Center
Funding period: 09/01/2020 – 09/31/2022
Total Direct Costs: $250,000

Funding agency: NIH
Grant Number: 2 R01 DK083402-06A1 (PI: Zavros)
Title of project: The role of Hedgehog Signaling in gastric tissue repair and regeneration
Funding period: 07/01/2016 – 04/30-2021 (NCE)
Total Direct Costs: $2,385,068 (30% effort)
Goals of the project: The objectives of this proposal are to 1) develop an understanding for the process of gastric regeneration, and to then 2) identify the mechanism by which the basic aging process of the stomach leads to an epithelium incapable of repair in response to injury.

Funding agency: NIH
Grant Number: 1U19AI116491-01, (Weiss and Wells PI, Zavros Project 1 PI)
Title of project: Organoids as a model system for studying gastrointestinal disease
Funding period: 05/01/2015 – 04/30/2021 (NCE)
Total Direct Costs: $1,483,920 (10% effort)
Goals of the project: The objective of this proposal is to identify the underlying mechanism by which H. pylori-host interactions trigger the disruption of epithelial cell differentiation using three-dimensional human gastric organoids generated through the directed differentiation of human pluripotent stem cells. We hypothesize that H. pylori primarily triggers hyperproliferation of the stem cell compartment in both the fundus and antrum leading to aberrant epithelial cell differentiation. Moreover, we hypothesize that differences in fundic pathology triggered by H. pylori are due to differences in target cell activation in the fundus versus antrum.

Funding agency: Goldman Pancreatic Cancer Grant, University of Cincinnati (PI: Zavros)
Title of project: Organoid-Based Preclinical Models of Pancreatic Cancer
Funding period: 09/01/2017 – 08/31/2019
Total Direct Costs: $110,000
Goals of the project: The objectives of this proposal are to develop patient-derived organoid models of pancreatic ductal adenocarcinoma (PDAC) to identify the mechanisms by which pancreatic cancer stem cells act as regulatory cells within the tumor microenvironment. The acquisition of such
knowledge is the first step required to achieve our long-term goal that is to better understand the development and maintenance of PDAC to develop an organoid-based platform for personalized medicine.

Project Number: 1 R01 DK083402-01, Zavros (PI)
Title of project: The role of Hedgehog Signaling in gastric tissue homeostasis and Disease
Funding period: 12/01/2010 – 11/30/2015
Total direct costs: $2,500,000 (50% effort)
Goals of the project: The major goal of this application is to identify the role of the Hedgehog signaling
pathway as a regulator of normal gastric epithelial cell differentiation, function and the development of gastric inflammation in response to Helicobacter pylori infection. We hypothesize that loss of Shh within the acid-secreting glands results in the disruption of gastric epithelial cell differentiation via activation of the Wnt signaling pathway.

Title of project: Advanced Multidisciplinary Training Program for Systems Biology
Funding period: 07/01/2013 – 06/30/2016
Total direct costs: $2,500,000
Goals of the project: The proposed Advanced Multidisciplinary Training Program for Systems Biology is designed to prime researchers to tackle complex mechanisms of human disease using cross-disciplinary approaches. Our goal is to award graduate student training slots to those students who fulfill
criteria that include dual mentorship by faculty working in different disciplines, and working in interdisciplinary teams to promote multidisciplinary learning. The objectives will be achieved by implementation of a training plan that incorporates the following features: 1) didactic and experiential training in interdisciplinary research concepts and approaches, 2) a student-centered and flexible curriculum custom tailored to meet the needs of each student via computational and biology elective courses, 3) a research project that will require the student to use interdisciplinary approaches under the mentorship of a multi-disciplinary set of faculty co-mentors, and 4) students engaged in a community that encourages interaction between students and mentors through seminars, data and journal clubs, and an annual retreat.

Title: Role of Hedgehog signaling in the development of gastric cancer
Funding period: 07/01/2010 – 06/31/2014
Total direct costs: $750,000 (30% effort)
Goals of the project: The goals of the project are to identify the mechanisms by which Shh expression and secretion drive cancer development. We hypothesize that during chronic inflammation Shh provides a continuous stimulus for the proliferation and engraftment of cancer-promoting cells and subsequently tumor growth.

Title: Role of inflammation and sonic hedgehog in the development of gastric cancer
Funding period: 06/01/2008 – 05/31/2009
Total direct costs: $25,000/year
Goals of project: The goals of the project are to first understand the role of sonic hedgehog in the maintenance of gastric epithelial cell differentiation, in particular the acid-secreting parietal cell. Second to determine the mechanism by which gastric inflammation, due to Helicobacter pylori infection results in disruption of sonic hedgehog expression and processing within the parietal cell. This mechanism is of significance to determining the role of inflammation as a trigger for parietal cell atrophy and the development of gastric cancer.

Title: Imaging the influx and engraftment of mesenchymal stem cells in the inflamed gastric mucosa
Funding Period: 01/01/2008-04/30/2008
Total direct costs: $15,000
Goals of project: Generate sufficient preliminary data for an NIH grant application to study mesenchymal stem cell (MSC) homing and engraftment to the gastric mucosa, in a new model with unique advantages. The consortium planning project will use the combined talents and resources available at 4
independent laboratories to prove the feasibility and utility of our approach for visualization and documentation of MSC in vivo within the gastric mucosa. Our specific goals are: 1) Implement an improved model system to allow us to accelerate stem cell homing and engraftment, and track these events in real time in living tissue, 2) Test the hypothesis that Sonic Hedgehog (Shh) regulates gastric mucosal cell differentiation and development from MSC cells and 3) Identify immune mediators that impact MSC homing to the gastric mucosa.
