Association Of Body Mass Index Genetic Risk Markers With Body Composition During Adolescence, Brice A. Smoker

Senior Theses

Background. Obesity affects nearly a fifth of all children in the United States and is a common risk factor for numerous chronic diseases. Many risk factors contribute to obesity, including race and genetics. Obesity is partially heritable, and many genetic loci have been identified as being associated with body mass index (BMI) in adults. Some of these loci have also been associated with childhood BMI, with effects strengthening with age. A previous genome-wide association study (GWAS) identified five single nucleotide polymorphisms (SNPs) associated with changes in BMI in children aged 1 – 17 years.

Purpose. The purpose of the current …

The Contribution Of Adipose Tissue From Ovariectomized Mice To Colon Cancer, Meredith Smith Carson

Theses and Dissertations

Obesity is considered a major public health concern worldwide due to the increased incidences of metabolic dysfunction and cancer risk. The obese state is, in part, attributable to the overconsumption of calorie-dense foods commonly seen in a standard Western diet, which aids in the progression of chronic, lowgrade inflammation. The role of estrogen varies depending on menopausal status, where estrogen deficiency coupled with increased visceral fat associated with post-menopause leads to increased secretions of pro-inflammatory adipokines and cytokines. However, the presence of estrogen in a premenopausal state has been shown to attenuate the pro-inflammatory response, which has been demonstrated when …

Macrophages And Associated Inflammation Differentially Impact Obesity, Colorectal Cancer And Obesity-Enhanced Colorectal Cancer, Jackie Bader

Theses and Dissertations

Colorectal Cancer (CRC) is the third-most common malignancy for men or women, with chronic inflammation considered as a primary risk factor. Obesity is also considered a chronic inflammatory disease and is associated with increased CRC incidence. Further, obesity and CRC occur in men and women differently with the highest incidence of either disease found in men, suggesting that female sex hormones may play a protective role in inflammatory diseases. Macrophages can promote inflammation and are a driving force in obesity-associated metabolic dysfunction. Conversely, macrophages also contribute to pro-tumoral responses including, proliferation, angiogenesis and tissue remodeling. This heterogeneity of macrophage behavior …
