Thesis Abstract

Abstract
MicroRNAs (miRNAs) are small non-coding RNA molecules that play crucial roles in gene regulation and are increasingly being recognized as key players in cancer progression and therapeutic potential. This thesis aims to explore the multifaceted roles of miRNAs in cancer biology, focusing on their involvement in tumor initiation, progression, metastasis, and response to therapy. Through a comprehensive review of the literature, this study provides insights into the diverse mechanisms by which miRNAs influence various aspects of cancer development and progression. Chapter 1 introduces the research topic, providing background information on miRNAs, cancer biology, and the current understanding of their roles in cancer. The problem statement highlights the gaps in knowledge that this study aims to address, and the objectives outline the specific goals and research questions. The limitations and scope of the study are discussed, along with the significance of the research and the structure of the thesis. Definitions of key terms are also provided to establish a common understanding of terminology used throughout the thesis. Chapter 2 presents a detailed literature review that synthesizes existing knowledge on miRNAs in cancer progression. Ten key themes are explored, including the dysregulation of miRNA expression in different cancer types, the functional roles of specific miRNAs in promoting or suppressing tumorigenesis, and the potential of miRNAs as diagnostic and prognostic biomarkers in cancer. Chapter 3 outlines the research methodology employed in this study, including the experimental approaches used to investigate miRNA expression patterns in cancer cells, the bioinformatics tools utilized to analyze miRNA target genes, and the in vitro and in vivo models used to study the functional effects of miRNAs on cancer progression. Eight key aspects of the research methodology are discussed in detail, highlighting the rigor and scientific validity of the study. Chapter 4 presents a comprehensive discussion of the findings, focusing on the impact of miRNAs on cancer cell proliferation, migration, invasion, and response to therapy. The results of experimental studies and bioinformatics analyses are critically evaluated, and the implications of the findings for understanding cancer biology and developing novel therapeutic strategies are discussed in depth. Chapter 5 concludes the thesis by summarizing the key findings and their implications for future research and clinical applications. The limitations of the study are acknowledged, and recommendations for further investigations are provided. The overall contribution of this research to the field of cancer biology and the potential translational impact on cancer therapy are highlighted. In conclusion, this thesis provides a comprehensive overview of the role of miRNAs in cancer progression and therapeutic potential, shedding light on the complex interplay between miRNAs and cancer biology. The findings presented in this study contribute to a deeper understanding of the molecular mechanisms underlying cancer development and offer insights into the potential use of miRNAs as diagnostic tools and therapeutic targets in the fight against cancer.
