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 critical roles in post-transcriptional gene regulation, including in cancer cells. This thesis explores the intricate mechanisms by which miRNAs regulate gene expression in cancer cells, with a focus on understanding their role in tumorigenesis and potential implications for cancer therapy. Chapter 1 provides an introduction to the study, presenting the background of miRNAs, the problem statement, objectives, limitations, scope, significance, and the overall structure of the thesis. The definitions of key terms related to miRNAs and cancer biology are also outlined to facilitate understanding. Chapter 2 comprises a comprehensive literature review that delves into existing research on miRNAs and their involvement in cancer development and progression. Ten key themes are identified and discussed, shedding light on the current understanding of the field. Chapter 3 details the research methodology employed in this study. It covers aspects such as sample collection, experimental techniques, data analysis, and statistical methods. The chapter is divided into eight sections to provide a clear overview of the research approach. In Chapter 4, the findings of the study are extensively discussed. The results of experiments investigating the role of specific miRNAs in regulating gene expression in cancer cells are presented and analyzed. The implications of these findings for cancer biology and potential therapeutic strategies are also explored. Finally, Chapter 5 concludes the thesis by summarizing the key findings and insights gained from the study. The significance of the research in advancing our understanding of miRNA-mediated gene regulation in cancer cells is highlighted, along with recommendations for future research directions in this field. In conclusion, this thesis contributes to the growing body of knowledge on the role of miRNAs in cancer biology. By elucidating the mechanisms by which miRNAs regulate gene expression in cancer cells, this study offers valuable insights that may pave the way for the development of novel therapeutic approaches for cancer treatment.
