Thesis Abstract

**Abstract
** Cancer is a complex and multifactorial disease characterized by uncontrolled cell growth and proliferation. Epigenetic modifications, which alter gene expression without changing the underlying DNA sequence, have emerged as critical players in cancer development. This thesis aims to investigate the role of epigenetic modifications in cancer development, focusing on how these modifications influence gene expression patterns and cellular behavior. The study will explore various epigenetic mechanisms, including DNA methylation, histone modifications, and non-coding RNAs, and their impact on key cellular processes such as cell cycle regulation, apoptosis, and metastasis. The literature review provides a comprehensive overview of current research on epigenetic modifications in cancer, highlighting the significance of aberrant epigenetic changes in tumorigenesis and tumor progression. Through an in-depth analysis of ten key studies, this chapter elucidates the diverse ways in which epigenetic alterations can drive cancer development and influence treatment outcomes. The research methodology section outlines the experimental approaches and techniques employed in this study, including cell culture assays, epigenetic profiling, and bioinformatics analysis, to investigate the epigenetic landscape of cancer cells. The findings from this investigation reveal intricate connections between epigenetic modifications and cancer development, underscoring the dynamic interplay between genetic and epigenetic factors in shaping the cancer phenotype. The discussion delves into the implications of these findings for cancer therapy and precision medicine, emphasizing the potential of targeting epigenetic vulnerabilities in cancer cells to develop novel treatment strategies. Furthermore, the study emphasizes the importance of considering the heterogeneity of epigenetic alterations across different cancer types and individual patients to optimize therapeutic interventions. In conclusion, this thesis provides valuable insights into the role of epigenetic modifications in cancer development, highlighting their potential as biomarkers for early detection and prognostic indicators for treatment response. By elucidating the intricate mechanisms underlying epigenetic dysregulation in cancer, this study contributes to advancing our understanding of cancer biology and paves the way for innovative therapeutic approaches targeting epigenetic vulnerabilities. The significance of this research lies in its potential to revolutionize cancer treatment paradigms and improve patient outcomes through personalized and targeted interventions based on the unique epigenetic profiles of individual tumors.
