Thesis Abstract

Abstract
MicroRNAs (miRNAs) are small non-coding RNA molecules that play a crucial role in the regulation of gene expression. In recent years, there has been increasing interest in understanding the role of miRNAs in cancer development and progression. This thesis aims to explore the intricate relationship between miRNAs and cancer, focusing on their involvement in tumor initiation, growth, metastasis, and response to therapy. Chapter 1 provides an introduction to the topic, presenting the background of the study and highlighting the problem statement. The objectives of the study are outlined, along with the limitations and scope of the research. The significance of the study is emphasized, and the structure of the thesis is detailed, along with the definition of key terms. Chapter 2 comprises a comprehensive literature review that examines the current understanding of miRNAs in cancer. Ten key areas are explored, including the biogenesis of miRNAs, their mechanisms of action, and their dysregulation in various cancer types. The role of miRNAs in cancer progression, metastasis, and drug resistance is also discussed. Chapter 3 focuses on the research methodology employed in this study. Eight key components are detailed, including the selection of miRNAs of interest, sample collection and processing, miRNA profiling techniques, bioinformatics analysis, and statistical methods used for data interpretation. The research design and ethical considerations are also addressed. Chapter 4 presents an in-depth discussion of the findings obtained from the study. The role of specific miRNAs in cancer development and progression is analyzed, with a focus on their potential as diagnostic biomarkers and therapeutic targets. The impact of miRNA dysregulation on key signaling pathways involved in cancer is also explored. Chapter 5 serves as the conclusion and summary of the thesis, highlighting the key findings and their implications for future research and clinical applications. The limitations of the study are acknowledged, and recommendations for further investigation are provided. Overall, this thesis contributes to the growing body of knowledge on the role of miRNAs in cancer and underscores the importance of understanding their complex interactions in cancer biology.
