Exploring the Role of MicroRNAs in Cancer Development and Progression

Thesis Abstract

Abstract
MicroRNAs (miRNAs) are small non-coding RNA molecules that play crucial roles in post-transcriptional gene regulation. In recent years, miRNAs have emerged as key regulators in various biological processes, including cancer development and progression. This thesis aims to explore the role of miRNAs in cancer by investigating their involvement in the initiation, progression, and metastasis of different types of cancer. The study focuses on understanding how dysregulation of miRNAs contributes to cancer pathogenesis and how targeting specific miRNAs could be utilized as a therapeutic strategy. Chapter One provides an introduction to the research topic, background information on miRNAs, the problem statement, objectives of the study, limitations, scope, significance, structure of the thesis, and definitions of key terms related to miRNAs and cancer. Chapter Two presents a comprehensive literature review that covers ten key aspects of miRNAs in cancer development and progression. This includes the role of miRNAs in cancer initiation, metastasis, drug resistance, and potential biomarkers for cancer diagnosis and prognosis. Chapter Three details the research methodology employed in this study. It outlines the experimental approaches, sample collection procedures, miRNA profiling techniques, bioinformatics analysis methods, and statistical tools utilized to investigate the role of miRNAs in cancer. Chapter Four focuses on the discussion of findings obtained from the study. It elaborates on the specific miRNAs identified to be dysregulated in various types of cancer, their target genes, and the molecular mechanisms underlying their involvement in cancer progression. Furthermore, this chapter discusses the potential therapeutic implications of targeting specific miRNAs in cancer treatment. In Chapter Five, the thesis concludes with a summary of the key findings, implications of the research, limitations of the study, and suggestions for future research directions. The study underscores the significance of miRNAs as critical regulators in cancer biology and highlights the potential of miRNA-based therapies for cancer management. Overall, this thesis contributes to the growing body of knowledge on the role of miRNAs in cancer development and progression, providing insights that could pave the way for the development of novel miRNA-based therapeutic strategies for cancer treatment.
