Exploring the Role of MicroRNAs in Regulating Gene Expression in Cancer Cells

Thesis Abstract

Abstract
MicroRNAs (miRNAs) are small non-coding RNA molecules that play crucial roles in post-transcriptional regulation of gene expression. In the context of cancer, dysregulation of miRNAs has been implicated in various aspects of tumorigenesis, including cell proliferation, apoptosis, and metastasis. This thesis aims to explore the specific roles of miRNAs in regulating gene expression in cancer cells, with a focus on understanding how these molecules contribute to the pathogenesis of cancer. Chapter One provides an introduction to the study, presenting the background of miRNAs, the problem statement, objectives, limitations, scope, significance, and the structure of the thesis. The definitions of key terms related to miRNAs and cancer are also outlined to provide a comprehensive understanding of the topic. Chapter Two presents a detailed literature review covering ten key aspects related to miRNAs and cancer. This includes an overview of miRNA biogenesis, their mechanisms of action in gene regulation, and the current understanding of their roles in cancer development and progression. The literature review also discusses the clinical implications of miRNAs in cancer diagnosis, prognosis, and therapy. Chapter Three outlines the research methodology employed in this study. It includes descriptions of the experimental approaches used to investigate the roles of specific miRNAs in regulating gene expression in cancer cells. The chapter covers sample collection, cell culture techniques, molecular biology methods, bioinformatics tools, and data analysis strategies. Chapter Four presents the findings of the study, showcasing the results obtained from experiments investigating the regulatory functions of select miRNAs in cancer cells. The discussion delves into the specific genes targeted by these miRNAs and the impact of their dysregulation on cancer cell behavior. Furthermore, the chapter explores the potential therapeutic implications of targeting these miRNAs in cancer treatment. Chapter Five offers a conclusion and summary of the thesis, highlighting the key findings, implications, and future research directions in the field of miRNAs and cancer. The thesis contributes to the growing body of knowledge on the intricate regulatory roles of miRNAs in cancer pathogenesis and underscores the potential of miRNAs as therapeutic targets in cancer treatment. In conclusion, this thesis sheds light on the essential roles of miRNAs in regulating gene expression in cancer cells. By elucidating the molecular mechanisms by which miRNAs influence cancer progression, this study provides valuable insights that may lead to the development of novel therapeutic strategies for combating cancer.
