Obesity-Induced Peritoneal Dissemination Of Ovarian Cancer And Dominant Recruitment Of Macrophages In Ascites, Rosa Mistica C. Ignacio, Eun-Sook Lee, Andrew J. Wilson, Alicia Beeghly-Fadiel, Margaret M. Whalen, Deok-Soo Son

Chemistry Faculty Research

One-fifth of cancer deaths are associated with obesity. Because the molecular mechanisms by which obesity affects the progression of ovarian cancer (OC) are poorly understood, we investigated if obesity could promote the progression of OC cells using the postmenopausal ob/ob mouse model and peritoneal dissemination of mouse ID8 OC cells. Compared to lean mice, obese mice had earlier OC occurrence, greater metastasis throughout the peritoneal cavity, a trend toward shorter survival, and higher circulating glucose and proinflammatory chemokine CXCL1 levels. Ascites in obese mice had higher levels of macrophages (Mφ) and chemokines including CCL2, CXCL12, CXCL13, G-CSF and M-CSF. Omental …

Effect Of Larval Starvation On Lipid Content Of Drosophila Melanogaster Over 15 Days, Fabian Leija, Allen Gibbs

LSAMP Poster Presentations

Starvation-resistant Drosophila melanogaster, common fruit flies, deriving from 121 generations of starvation selection, have resulted in genetically, behaviorally, and physiologically different individuals compared to non-resistant counterparts. Starvation-resistant Drosophila are more obese, containing twice as much lipids as control flies.This is a result of starvation-resistant fly larva feeding for 5 days and then entering the pupa stage while non-resistant flies only feed for 4 days.

In this experiment, we hope to answer the question of whether the starvation-resistant flies are genetically predisposed to be substantially more obese than wild populations or if it is a result of this alternate behavior …

Obesity, Noah Rhodes

Global Issues in Public Health

Obesity is a worldwide issue that can be defined as a non-communicable condition which means that it is non-infectious and non-transmissible and it is defined as having a BMI over 30 even though BMI doesn’t account for the person’s muscle mass which causes some athletes to be considered obese just because they weigh a lot for their height. Diagnosing obesity can be a long process which includes a health history being taken, a general physical exam, calculation of BMI, and measuring waist circumference. Diagnosis of obesity also involves checking for problems such as high blood pressure, variation of cholesterol levels …
