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 the regulation of gene expression. In cancer cells, dysregulation of miRNAs has been associated with tumorigenesis, metastasis, and drug resistance. This thesis aimed to explore the specific roles of miRNAs in regulating gene expression in cancer cells, focusing on their impact on cancer progression and potential therapeutic implications. Chapter 1 provides an introduction to the study, including the background of miRNA research in cancer, the problem statement regarding the dysregulation of miRNAs in cancer cells, the objectives of the study to investigate the specific roles of miRNAs, the limitations and scope of the research, the significance of the study in advancing cancer research, the structure of the thesis outlining the chapters, and the definition of key terms used throughout the study. Chapter 2 presents a comprehensive literature review covering ten key areas related to miRNAs in cancer, including the biogenesis of miRNAs, the mechanisms of miRNA-mediated gene regulation, the dysregulation of miRNAs in cancer, the role of miRNAs in cancer progression, metastasis, and drug resistance, the potential of miRNAs as diagnostic and prognostic markers, and the therapeutic targeting of miRNAs in cancer treatment. Chapter 3 details the research methodology employed in this study, including the experimental design, cell culture techniques, miRNA profiling methods, gene expression analysis, bioinformatics tools used for data analysis, and statistical approaches applied to interpret the results. The chapter also discusses the ethical considerations and potential biases in the research process. Chapter 4 presents a thorough discussion of the findings obtained from the study, highlighting the specific miRNAs identified to be dysregulated in cancer cells and their target genes involved in cancer-related pathways. The chapter explores the functional roles of these miRNAs in regulating gene expression and their implications for cancer progression. Furthermore, the potential therapeutic strategies targeting these dysregulated miRNAs are discussed. Chapter 5 provides a conclusion and summary of the thesis, summarizing the key findings, implications of the research, and potential future directions in the field of miRNA-based cancer therapeutics. The study underscores the importance of understanding the roles of miRNAs in cancer cells for developing targeted therapies that could improve cancer treatment outcomes. In conclusion, this thesis contributes to the current understanding of how miRNAs regulate gene expression in cancer cells and highlights the potential of miRNAs as diagnostic biomarkers and therapeutic targets in cancer. The findings of this study provide valuable insights into the complex molecular mechanisms underlying cancer progression and offer new avenues for developing more effective and personalized cancer treatments.
