The Role of MicroRNAs in Cancer Progression: Mechanisms and Therapeutic Potential

Thesis Abstract

Abstract
MicroRNAs (miRNAs) are small non-coding RNA molecules that play crucial roles in the regulation of gene expression at the post-transcriptional level. In recent years, there has been a growing interest in understanding the role of miRNAs in cancer progression, as dysregulation of miRNA expression has been implicated in various aspects of tumorigenesis, including tumor initiation, growth, invasion, and metastasis. This thesis explores the mechanisms by which miRNAs contribute to cancer progression and the potential therapeutic opportunities that targeting miRNAs may offer in the treatment of cancer. Chapter One provides an introduction to the topic, including background information on miRNAs, the problem statement regarding their involvement in cancer progression, the objectives of the study, the limitations and scope of the research, the significance of the study, the structure of the thesis, and the definition of key terms. Chapter Two presents a comprehensive literature review that examines the current understanding of miRNA dysregulation in various types of cancer. The chapter discusses the specific miRNAs that have been implicated in cancer progression and their roles in regulating key oncogenic pathways. Chapter Three details the research methodology employed in this study, including the experimental approaches used to investigate the mechanisms by which miRNAs contribute to cancer progression. The chapter outlines the study design, sample collection and analysis methods, data interpretation techniques, and statistical analysis procedures. Chapter Four presents an in-depth discussion of the findings obtained from the research, including the identification of key miRNAs involved in cancer progression, their target genes, and the molecular mechanisms underlying their oncogenic functions. The chapter also discusses the potential therapeutic strategies that target miRNAs for the treatment of cancer. Chapter Five concludes the thesis by summarizing the key findings of the study and their implications for the field of cancer research. The chapter also discusses the potential future directions for research in this area and the clinical applications of targeting miRNAs in cancer therapy. Overall, this thesis provides valuable insights into the role of miRNAs in cancer progression, highlighting the complex regulatory networks that govern tumorigenesis and the potential therapeutic opportunities that targeting miRNAs may offer in the treatment of cancer.
