Exploring the Role of MicroRNAs in Cancer Development and Progression

Thesis Abstract

Abstract
Cancer is a complex disease characterized by uncontrolled cell growth and proliferation, leading to the formation of tumors. MicroRNAs (miRNAs) are small non-coding RNA molecules that play crucial roles in regulating gene expression and have been implicated in various cellular processes, including cancer development and progression. This thesis aims to explore the role of miRNAs in cancer, focusing on their involvement in the initiation, promotion, and metastasis of tumors. Chapter One provides an introduction to the topic, including background information on miRNAs, the problem statement, objectives of the study, limitations, scope, significance, and structure of the thesis. The definitions of key terms related to miRNAs and cancer are also provided to establish a foundational understanding for the subsequent chapters. Chapter Two presents a comprehensive literature review of current research on miRNAs in cancer, highlighting key findings and identifying gaps in knowledge. The review covers various aspects, including the dysregulation of miRNAs in different cancer types, their mechanisms of action, and their potential diagnostic and therapeutic implications. Chapter Three outlines the research methodology employed in this study. This chapter details the experimental techniques used to investigate the expression profiles of specific miRNAs in cancer cells and tissues, as well as the bioinformatics analyses employed to identify miRNA targets and pathways associated with cancer development and progression. Chapter Four presents the findings of the study, focusing on the role of specific miRNAs in promoting cancer cell proliferation, migration, and invasion. The results demonstrate the dysregulation of miRNAs in cancer cells and their impact on key signaling pathways involved in tumor growth and metastasis. Chapter Five summarizes the key findings of the study and provides a conclusion based on the results obtained. The implications of the research findings for cancer diagnosis, prognosis, and treatment are discussed, along with recommendations for future research directions in the field of miRNA-based cancer therapeutics. Overall, this thesis contributes to the growing body of knowledge on the role of miRNAs in cancer development and progression, shedding light on the intricate molecular mechanisms underlying tumorigenesis and offering insights into potential therapeutic strategies for combating this deadly disease.
