Exploring the Role of MicroRNA Biomarkers in Diagnosis and Prognosis of Cancer

Thesis Abstract

Abstract
Cancer remains a significant health challenge globally, with early diagnosis and accurate prognosis being crucial for effective treatment and improved patient outcomes. MicroRNAs (miRNAs) have emerged as promising biomarkers in cancer research due to their regulatory role in gene expression and their stability in various biological samples. This thesis aims to explore the role of miRNA biomarkers in the diagnosis and prognosis of cancer, focusing on their potential applications in clinical practice. The introduction outlines the background of the study, highlighting the importance of early cancer detection and the limitations of current diagnostic methods. The problem statement emphasizes the need for novel biomarkers that can enhance early detection and improve prognostic accuracy in cancer patients. The objectives of the study include investigating the specific miRNA signatures associated with different cancer types, evaluating their diagnostic and prognostic value, and exploring the molecular mechanisms underlying their dysregulation in cancer. The literature review encompasses ten key areas, including the biology of miRNAs, their role in cancer development and progression, current methods for miRNA detection, and previous studies on miRNA biomarkers in various cancer types. The research methodology section details the experimental approach, sample collection and processing methods, miRNA profiling techniques, data analysis strategies, and statistical methods employed in the study. The discussion of findings chapter presents the results of miRNA profiling in cancer samples, highlighting the identification of specific miRNA signatures associated with different stages of cancer progression and treatment response. The analysis of miRNA-target interactions and signaling pathways provides insights into the molecular mechanisms underlying the dysregulation of miRNAs in cancer and their potential as therapeutic targets. In conclusion, this thesis underscores the significance of miRNA biomarkers in cancer diagnosis and prognosis, emphasizing their potential clinical utility for personalized treatment strategies and precision medicine approaches. The summary highlights the key findings of the study, including the identification of novel miRNA signatures and their implications for cancer management. Overall, this research contributes to the growing body of knowledge on miRNA biomarkers and their role in advancing cancer diagnostics and personalized medicine.
