Assessing Feasibility And Readiness To Address Obesity Through Policy In American Indian Reservations, Valarie Blue Bird Jernigan, Gail Boe, Carolyn Noonan, Leslie Carroll, Dedra Buchwald Oct 2016

Assessing Feasibility And Readiness To Address Obesity Through Policy In American Indian Reservations, Valarie Blue Bird Jernigan, Gail Boe, Carolyn Noonan, Leslie Carroll, Dedra Buchwald

Journal of Health Disparities Research and Practice

The Institute of Medicine and Centers for Disease Control and Prevention (CDC) have identified policy and environmental strategies as critical to the prevention and control of obesity. However such strategies are rare in American Indian communities despite significant obesity-related disparities. Tribal policymaking processes differ by tribal nation and are often poorly understood by researchers and public health practitioners, hindering the dissemination, implementation, and successful scale-up of evidence-base obesity strategies in tribal communities. To address these gaps in knowledge we surveyed 138 diverse stakeholders in two American Indian reservations to assess the feasibility of and readiness to implement CDC-recommended obesity policy ...


The Contributions Of Skeletal Muscle Pkc Theta To Diet-Induced Obesity, Erika Harness, Joseph S. Marino, Phd, Yvette Huet, Phd Aug 2016

The Contributions Of Skeletal Muscle Pkc Theta To Diet-Induced Obesity, Erika Harness, Joseph S. Marino, Phd, Yvette Huet, Phd

Journal of Health Disparities Research and Practice

Protein Kinase C- Theta (PKCθ) is a gene predominantly expressed in hematopoietic cells and skeletal muscle. In skeletal muscle, PKCθ regulates fat metabolism and insulin sensitivity. PKCθ activity increases in response to high levels of diacylglycerol in the cell, a common outcome of chronic high fat diet consumption and obesity. PKCθ is associated with skeletal muscle metabolic dysfunction, which may exacerbate weight gain and metabolic disease. The purpose of this study was to test the hypothesis that the selective deletion of PKCθ from skeletal muscle protects against diet-induced obesity.

Mice lacking PKCθ in skeletal muscle were created using Cre-Lox recombination ...


An Intervention To Promote Navajo Gardening, Nutrition, And Community Wellness, Sonia Avitia, Mark C. Bauer, Phd, Linda Garcia Aug 2016

An Intervention To Promote Navajo Gardening, Nutrition, And Community Wellness, Sonia Avitia, Mark C. Bauer, Phd, Linda Garcia

The rates of diabetes and obesity in Navajo communities are higher than national rates. A healthy diet of fresh fruits and vegetables will help to prevent and reduce such rates. So the project focuses on promoting gardening to make vegetables and fruits more accessible at the comfort of one’s own home. Previous research in this area shows that gardeners consume 2 more servings of fruits and vegetables than nongardeners. Thirty participants were recruited by flyer distribution at chapter houses, senior centers, and community centers, from four Navajo targeted areas: Shiprock, NM; Tsaile, AZ; Lukachukai, AZ, and Hogback, NM. With ...


Leptin Induces Proliferation And Notch Expression In Pancreatic Cancer, Felice Watson, Ruben Gonzalez-Perez, Phd Aug 2016

Leptin Induces Proliferation And Notch Expression In Pancreatic Cancer, Felice Watson, Ruben Gonzalez-Perez, Phd

Journal of Health Disparities Research and Practice

Pancreatic adenocarcinoma (PA) is an aggressive cancer. It develops in a way that causes almost no detectable symptoms, which leads to a rapid progression and a short survival rate.

Researchers have discovered a link between pancreatic cancer (and other cancer types) and obesity. High levels of leptin, an appetite hormone secreted by adipocytes, have been found in obese people. Studies have shown that the absence of leptin in the body or severe leptin resistance can lead to uncontrolled eating and weight gain, hence, its connection to obesity. Consequently, our lab is analyzing the relationship between obesity and leptin and what ...


Exploration Of Antagonist Efficacy For Lpra2 Like Peptide, Ayobami Loye, Ruben R. Gonzalez-Perez, Phd Aug 2016

Exploration Of Antagonist Efficacy For Lpra2 Like Peptide, Ayobami Loye, Ruben R. Gonzalez-Perez, Phd

Journal of Health Disparities Research and Practice

Leptin is a small protein hormone that controls satiety and is produced by adipocytes. Obese people have increased levels of circulating leptin. Excessive leptin levels cause a break down in the control of leptin signaling pathways leading to increased angiogenesis, proliferation, cell migration, invasion, and anti-apoptotic events. Obesity and leptin signaling have been linked to cancer progression. Literature shows that LPrA2 is an effective leptin antagonist as it decreases proliferation of breast cancer cells in vitro.

This project compares the effectiveness of LPrA2 like compounds in breast cancer cell-line MDA-MB-468 (M-468 BCs). We hypothesize that the new peptide antagonists have ...
