Mcp-1 In Colorectal Cancer: Benefits Of Exercise, Jamie Lee Mcclellan

Theses and Dissertations

The etiology of colon cancer is a complex phenomenon that involves both genetic and environmental factors. However, only about 20% have a familial basis with the largest fraction being attributed to environmental causes that can lead to chronic inflammation. Tumors associated macrophages drive the pro-inflammatory response in the tumor micro-environment and are associated with poor prognosis in certain cancers. Monocyte chemoattractant protein 1 (MCP-1) is thought to be the most important chemokine for recruitment of macrophages to the tumor microenvironment. In chapter 1, we examined the timing and magnitude of the intestinal inflammatory cytokine response in relation to tumorigenesis in …

Six1 Overexpression Promotes Epithelial– Mesenchymal Transition And Malignant Progression In Models Of Cervical And Colon Cancer, Hanwen Xu

Theses and Dissertations

Inappropriate expression of embryonic genes, particularly homeodomain transcription factors, contributes to tumorigenesis and tumor progression. The overexpression of Six1, a member of the Six family of homeodomain transcription factors, has been found in various human cancers, and is associated with tumor progression and metastasis. We have previously determined that the expression of SIX1 mRNA increased during in vitro progression of human papillomavirus type 16 (HPV16)- immortalized human keratinocytes (HKc/HPV16) toward a differentiation-resistant (HKc/DR) phenotype. However, the mechanism(s) of how Six1 promotes HPV16- mediated transformation remain unknown. In this study, we explored the role of Six1 at early stages and late …

Longitudinal Changes In The Inflammatory Potential Of Diet And Risk Of Cancer In Women, Fred Kinyuytabung

Theses and Dissertations

Introduction: The dietary inflammatory index (DII) assesses an individual’s overall diet quality with regards to its inflammatory potential on a continuum from maximally anti-inflammatory (lower or healthier DII scores) to maximally pro-inflammatory (higher or unhealthy DII scores). The DII measured at one point in time has been associated with cancer risk in previous studies; however, data are lacking regarding the change in DII over time and how these changes impact cancer risk. We assessed changes in the DII, and evaluated associations between cumulative history, and changes over time in dietary inflammatory potential, and risk of colorectal cancer (CRC) and breast …

Trends And Determinants Of Up-To-Date Status With Colorectal Cancer Screening In Tennessee, 2002-2008, Sreenivas P. Veeranki, Shimin Zheng

ETSU Faculty Works

BACKGROUND:

Screening rates for colorectal cancer (CRC) are increasing nationwide including Tennessee (TN); however, their up-to-date status is unknown. The objective of this study is to determine the trends and characteristics of TN adults who are up-to-date status with CRC screening during 2002-2008.

METHODS:

We examined data from the TN Behavioral Risk Factor Surveillance System for 2002, 2004, 2006 and 2008 to estimate the proportion of respondents aged 50 years and above who were up-to-date status with CRC screening, defined as an annual home fecal occult blood test and/or sigmoidoscopy or colonoscopy in the past 5 years. We identified trends …

Individual, Disease, And Work-Related Factors Associated With Work Patterns, Presenteeism And Sick Pay Policy Of The Colorectal Cancer Survivor After Treatment, Kristin A. Roper

Graduate Doctoral Dissertations

Participation of colorectal cancer survivors (CRC) in the workforce has been described by clinicians, survivors, and researchers as a way to improve mood, quality of life (QOL), and survival. Maintaining self-esteem and financial independence have also been attributed to continued employment of the CRC survivor. The purpose of this cross-sectional survey was to describe patterns of employment of the CRC survivor and to examine the individual, disease, and work-related factors that influence presenteeism and perceived adequacy of sick pay (ASP) policy. The Conceptual Model of Nursing and Health Policy and the Pathways to Work Life Recovery guided the design, selection …
