Exploring the role of microRNAs in cancer progression and therapy resistance

Thesis Abstract

Abstract
MicroRNAs (miRNAs) have emerged as key players in cancer biology, with significant implications for cancer progression and therapy resistance. This thesis explores the role of miRNAs in cancer progression and therapy resistance, focusing on their regulatory functions in cancer cells. The study investigates the dysregulation of specific miRNAs in cancer, their impact on tumor development, metastasis, and resistance to therapy, providing insights into potential therapeutic strategies targeting miRNAs for cancer treatment. Chapter 1 provides an introduction to the research topic, including the background of the study, problem statement, objectives, limitations, scope, significance, structure of the thesis, and definitions of key terms. Chapter 2 presents a comprehensive literature review comprising ten key areas related to miRNAs in cancer progression and therapy resistance. The review discusses the current understanding of miRNA dysregulation in various cancer types, their roles in promoting tumor growth, metastasis, and resistance to conventional therapies. Chapter 3 details the research methodology employed in this study, including sample collection, miRNA profiling techniques, bioinformatics analysis, and experimental approaches to investigate the functional roles of specific miRNAs in cancer progression and therapy resistance. The chapter outlines the experimental design, data analysis methods, and statistical approaches used to interpret the findings. In Chapter 4, the discussion of findings delves into the results obtained from the experimental investigations, highlighting the dysregulated miRNAs identified in cancer cells, their functional roles in promoting tumorigenesis and therapy resistance, as well as the molecular mechanisms underlying their actions. The chapter also examines the potential implications of targeting specific miRNAs as therapeutic interventions in cancer treatment. Chapter 5 concludes the thesis by summarizing the key findings, discussing their implications for cancer research and therapy development. The study underscores the importance of miRNAs as critical regulators of cancer progression and therapy resistance, emphasizing the potential of miRNA-based therapeutics in improving cancer treatment outcomes. Future directions for research and clinical applications of miRNA-targeted therapies are also addressed in the conclusion. In conclusion, this thesis provides valuable insights into the role of miRNAs in cancer progression and therapy resistance, highlighting the potential of miRNA-based strategies for precision medicine in cancer treatment. The findings contribute to the growing body of knowledge on miRNA biology in cancer and lay the groundwork for future research aimed at harnessing the therapeutic potential of miRNAs for personalized oncology interventions.
