Exploring the Role of MicroRNAs in Cancer Progression and Treatment Resistance

Thesis Abstract

Abstract
Cancer remains a significant global health challenge, with treatment resistance and disease progression posing major obstacles in achieving successful outcomes. This thesis delves into the intricate world of microRNAs (miRNAs) and their pivotal role in cancer progression and treatment resistance. MicroRNAs are small non-coding RNA molecules that function as crucial regulators of gene expression, thereby influencing various cellular processes, including proliferation, apoptosis, and metastasis. The introduction provides a comprehensive overview of the research topic, highlighting the importance of understanding the molecular mechanisms underlying cancer progression and treatment resistance. The background of the study delves into the existing body of literature on the role of microRNAs in cancer, emphasizing the need for further exploration in this field. The problem statement underscores the critical gaps in knowledge that this research aims to address, particularly in elucidating the specific miRNAs involved in treatment resistance and their potential as therapeutic targets. The objectives of the study outline the specific goals and research questions that guide this investigation, aiming to identify key miRNAs associated with cancer progression and treatment resistance. The limitations of the study acknowledge the constraints and challenges encountered during the research process, while the scope of the study delineates the boundaries and focus areas of the investigation. The significance of the study underscores the potential impact of the findings on advancing our understanding of cancer biology and improving treatment strategies. The literature review synthesizes existing research on miRNAs in cancer, examining the roles of different miRNAs in promoting tumor development, metastasis, and resistance to various therapies. The research methodology details the experimental approaches and techniques employed to investigate miRNA expression profiles, functional analyses, and their interactions with target genes in cancer cells. The discussion of findings analyzes the experimental results, highlighting the key miRNAs identified and their functional implications in cancer progression and treatment resistance. The conclusion summarizes the main findings of the study, emphasizing the potential clinical relevance of targeting specific miRNAs for therapeutic interventions in cancer. Overall, this thesis sheds light on the complex interplay between miRNAs and cancer pathogenesis, offering new insights into potential strategies for overcoming treatment resistance and improving patient outcomes in the fight against cancer.
