Thesis Abstract

Abstract
Cancer is a complex and multifaceted disease that continues to pose significant challenges to human health worldwide. MicroRNAs (miRNAs) have emerged as crucial regulators of gene expression, playing pivotal roles in various cellular processes, including those involved in cancer development and progression. This thesis focuses on exploring the role of miRNAs in cancer, with a particular emphasis on their involvement in promoting tumor initiation, growth, metastasis, and resistance to therapy. The introductory chapter sets the stage by providing a comprehensive overview of the background of the study, outlining the problem statement, objectives, limitations, scope, significance of the study, structure of the thesis, and defining key terms to enhance understanding. Chapter two delves into a detailed literature review encompassing ten critical aspects related to miRNAs and cancer, highlighting existing knowledge gaps and key findings in the field. Chapter three presents the research methodology employed in this study, including the study design, sample collection, miRNA profiling techniques, data analysis methods, and statistical approaches utilized to investigate the role of miRNAs in cancer development and progression. The methodology section also discusses the ethical considerations and potential biases that may have influenced the study outcomes. Chapter four offers an in-depth discussion of the findings obtained from the research, presenting a comprehensive analysis of the role of specific miRNAs in different types of cancer, their molecular mechanisms of action, and their clinical implications. The chapter also explores potential therapeutic strategies targeting miRNAs to combat cancer progression and improve patient outcomes. In the concluding chapter, the key findings of the study are summarized, and their implications for cancer research and therapy are discussed. The limitations of the study are acknowledged, and future research directions are proposed to further elucidate the role of miRNAs in cancer progression. Overall, this thesis contributes valuable insights into the intricate network of miRNA-mediated regulatory mechanisms in cancer and underscores the potential of miRNAs as diagnostic biomarkers and therapeutic targets in oncology.
