Investigating the Role of MicroRNAs in Cancer Development and Progression.

Thesis Abstract

Abstract
Cancer remains a significant global health burden, with a complex and multifaceted etiology. Among the various molecular mechanisms implicated in cancer development and progression, microRNAs (miRNAs) have emerged as key regulators of gene expression and cellular processes. This thesis investigates the role of miRNAs in cancer, focusing on their involvement in the development and progression of various cancer types. The study aims to provide a comprehensive understanding of how miRNAs contribute to cancer pathogenesis and to explore their potential as diagnostic biomarkers and therapeutic targets. The introductory chapter sets the stage by providing a background of the study, presenting the problem statement, objectives, limitations, scope, significance, structure of the thesis, and definitions of key terms related to miRNAs and cancer. The literature review chapter critically examines existing research on the role of miRNAs in cancer, highlighting key studies that have elucidated the molecular mechanisms underlying miRNA dysregulation in different cancer types. The chapter also discusses the potential clinical implications of miRNAs as biomarkers and therapeutic targets in cancer treatment. The research methodology chapter outlines the experimental approach employed in this study, including sample collection, miRNA profiling techniques, bioinformatics analysis, and statistical methods used for data interpretation. The chapter also details the selection criteria for study participants, ethical considerations, and quality control measures implemented to ensure the reliability and validity of the study results. In the discussion of findings chapter, the results of the study are presented and critically analyzed in the context of the existing literature. The chapter discusses the differential expression of miRNAs in cancer tissues compared to normal tissues, the functional roles of specific miRNAs in cancer progression, and the potential mechanisms underlying miRNA dysregulation in cancer cells. The implications of these findings for cancer diagnosis, prognosis, and treatment are also explored. Finally, the conclusion and summary chapter provide a comprehensive overview of the key findings of the study, highlighting the main contributions to the field of cancer research. The chapter also discusses the limitations of the study, future research directions, and the potential clinical applications of miRNAs as biomarkers and therapeutic targets in cancer management. 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 regulatory networks that drive oncogenic processes. The findings of this study have the potential to inform the development of novel diagnostic and therapeutic strategies for improving cancer patient outcomes.
