Thesis Abstract

Abstract
Cancer is a complex and multifaceted disease that continues to pose significant challenges to healthcare professionals and researchers worldwide. In recent years, the emerging field of microRNAs (miRNAs) has garnered considerable attention due to their pivotal roles in regulating gene expression and cellular processes. This thesis investigates the role of miRNAs in cancer development and progression, with a focus on understanding their mechanisms of action and potential implications for cancer diagnosis and treatment. The introductory chapter provides a comprehensive overview of the study, including the background, problem statement, objectives, limitations, scope, significance, and structure of the thesis. Definitions of key terms related to miRNAs and cancer are also provided to establish a solid foundation for the subsequent chapters. The literature review chapter critically examines existing research on miRNAs and their involvement in various types of cancer. Ten key themes are explored, including the dysregulation of miRNAs in cancer, their impact on tumor initiation and progression, and their potential as diagnostic and prognostic biomarkers. The research methodology chapter outlines the approach taken to investigate the role of miRNAs in cancer. Eight key components are discussed, such as the selection of study samples, miRNA profiling techniques, data analysis methods, and validation strategies. The findings chapter presents a detailed discussion of the results obtained from the study, highlighting the specific miRNAs implicated in cancer development and progression. The potential mechanisms by which these miRNAs exert their effects on tumorigenesis are explored, providing insights into novel therapeutic targets and diagnostic strategies. In the conclusion and summary chapter, the key findings of the study are synthesized and contextualized within the broader landscape of cancer research. The implications of the study for cancer diagnosis, prognosis, and therapy are discussed, along with recommendations for future research directions in the field of miRNA-based cancer therapeutics. Overall, this thesis contributes to our understanding of the role of miRNAs in cancer development and progression, shedding light on the intricate molecular mechanisms underlying this complex disease. By elucidating the functions of miRNAs in cancer biology, this research has the potential to inform the development of innovative approaches for cancer diagnosis and treatment, ultimately improving patient outcomes and advancing the field of oncology.
