This book presents original results on the leading edge of cancer research. Chapter One summarizes what is currently known regarding the epigenetic regulation of osteosarcoma pathways and oncogenes, as well as clinical trials of drugs that exert epigenetic regulation. Chapter Two critically discusses the role of ECM-dependent signaling in osteosarcoma progression. Chapter Three illustrates the harmful effects of ultraviolet radiation exposure by focusing on photocarcinogenesis. Chapter Four examines the psychology of sunscreen use and outlines the key psychological factors associated with sunscreen use. Chapter Five reviews the cellular and molecular mechanism of Regulatory T cells (Tregs) and Transforming Growth Factor-ss mediating cervical cancer development. Chapter Six examines the affect of the American cranberry extract on expression of insulin-like growth factor-I and insulin-like growth factor binding proteins in human prostate cancer cells in vitro. Chapter Seven discusses the design of synthetic peptides to specifically interfere the papillomavirus binding factor/14-3-3beta binding to restore papillomavirus binding factor apoptotic functions. Chapter Eight examines brain development using correlations between Diffusion Kurtosis and neurite orientation dispersion and density imaging (NODDI) in neonates and young children. Chapter Nine highlights the opportunities that are available to prevent the late effects related to stress and fears, emphasizing the importance of teaching patients resiliency and how to cope.
