Thesis Abstract

Abstract
The intricate molecular mechanisms underlying cancer progression continue to be a focal point of research in the field of biochemistry. MicroRNAs (miRNAs) have emerged as key regulators of gene expression and have been implicated in various biological processes, including cancer development and progression. This thesis delves into the exploration of the role of miRNAs in cancer progression, with a specific focus on their involvement in tumor initiation, growth, metastasis, and therapeutic resistance. Chapter one provides the foundation for this study, starting with an introduction to the significance of miRNAs in cancer biology. The background of the study elucidates the current understanding of miRNA functions and their dysregulation in cancer. The problem statement highlights the gaps in knowledge that necessitate further investigation, while the objectives of the study outline the specific goals and research questions. The limitations and scope of the study are discussed to provide clarity on the boundaries and constraints of the research. The significance of the study emphasizes the potential impact of the findings on cancer research and therapy. Finally, the structure of the thesis and definition of terms establish the framework for the subsequent chapters. Chapter two presents a comprehensive literature review that synthesizes existing knowledge on miRNAs and their role in cancer progression. Ten key aspects are explored, including the biogenesis of miRNAs, their mechanisms of action, and their impact on cancer hallmarks such as proliferation, invasion, and immune evasion. Chapter three details the research methodology employed in this study. Eight components are discussed, covering aspects such as sample collection, miRNA profiling techniques, bioinformatics analysis, and statistical methods used for data interpretation. This chapter provides insights into the experimental design and analytical approaches that were instrumental in investigating the role of miRNAs in cancer progression. Chapter four presents an in-depth discussion of the findings derived from the study. The analysis of miRNA expression patterns in different cancer types, their functional roles in promoting or suppressing tumorigenesis, and their potential as therapeutic targets are elaborated upon. The implications of these findings for understanding cancer progression mechanisms and developing novel treatment strategies are critically examined. Chapter five serves as the conclusion and summary of the thesis. The key findings, implications, and limitations of the study are summarized, providing a comprehensive overview of the research outcomes. Future research directions and potential clinical applications of miRNA-based therapies in cancer treatment are also discussed. In conclusion, this thesis contributes to the growing body of knowledge on the role of miRNAs in cancer progression, shedding light on the intricate molecular pathways that drive tumorigenesis and metastasis. The findings presented herein have the potential to advance our understanding of cancer biology and pave the way for innovative therapeutic interventions targeting miRNAs in the fight against cancer.
