Exploring the Role of MicroRNAs in Cancer Progression: Implications for Targeted Therapies

Thesis Abstract

Abstract
The intricate regulatory role of microRNAs (miRNAs) in cancer progression has gained significant attention in recent years due to their potential as novel therapeutic targets. This thesis delves into the exploration of miRNAs and their implications for targeted therapies in cancer. The study begins with an introduction highlighting the significance of miRNAs in cancer biology and the urgent need for innovative treatment strategies. The background of the study provides a comprehensive overview of miRNA biogenesis, function, and dysregulation in cancer, setting the stage for a detailed investigation into their role in tumorigenesis and metastasis. The problem statement underscores the limitations of current cancer therapies and emphasizes the potential of miRNAs as promising candidates for targeted interventions. The objectives of the study are outlined to elucidate the specific aims of exploring the relationship between miRNAs and cancer progression, identifying key miRNAs involved in oncogenesis, and evaluating the therapeutic potential of targeting miRNAs in cancer treatment. The limitations of the study are acknowledged, including the complexities of miRNA research and the challenges associated with clinical translation. The scope of the study delineates the focus on specific miRNAs implicated in different cancer types and their mechanistic roles in promoting or inhibiting tumorigenesis. The significance of the study lies in its potential to contribute to the development of personalized cancer therapies that target specific miRNAs to modulate tumor growth and metastasis. The structure of the thesis provides a roadmap for navigating the chapters, from the introduction to the conclusion, ensuring a coherent flow of information. Defined terms and concepts related to miRNAs, cancer progression, and targeted therapies are clarified to facilitate a comprehensive understanding of the research findings. The literature review encompasses ten key studies that highlight the current knowledge on miRNA dysregulation in cancer and the therapeutic strategies aimed at modulating miRNA expression for clinical benefit. The research methodology section outlines the experimental approaches used to investigate miRNA expression profiles, target identification, and functional validation in cancer cell lines and animal models. The discussion of findings delves into the intricate interplay between miRNAs and cancer pathways, highlighting the potential of miRNA-based therapies to overcome drug resistance and improve patient outcomes. In conclusion, this thesis underscores the pivotal role of miRNAs in cancer progression and emphasizes the promising implications of targeting miRNAs for precision medicine in oncology. By elucidating the complex regulatory networks governed by miRNAs, this study aims to pave the way for innovative targeted therapies that could revolutionize cancer treatment paradigms and improve patient survival rates.
