Cancer progression and therapy resistance remain significant challenges in oncology, leading to high mortality rates worldwide. MicroRNAs (miRNAs) have emerged as key regulators in cancer biology, influencing tumorigenesis, metastasis, and response to therapy. This thesis investigates the role of miRNAs in cancer progression and therapy resistance, aiming to enhance our understanding of the molecular mechanisms underlying these processes. The introduction provides a comprehensive overview of cancer biology, highlighting the importance of miRNAs as critical players in cancer development. The background of the study delves into the biogenesis and functions of miRNAs, emphasizing their regulatory roles in gene expression and signaling pathways. The problem statement underscores the urgent need to decipher the intricate interplay between miRNAs and cancer progression to identify novel therapeutic targets and strategies. The objectives of the study are outlined to elucidate the specific aims and research questions addressed in this thesis. By investigating the dysregulation of miRNAs in cancer cells, the study aims to identify key miRNAs implicated in tumor progression and therapy resistance. The limitations of the study are acknowledged, including the complexity of miRNA networks and the challenges in translating research findings into clinical applications. The scope of the study encompasses a multidisciplinary approach, integrating bioinformatics, cell biology, and molecular techniques to unravel the functional impact of miRNAs in cancer biology. The significance of the study lies in its potential to uncover novel biomarkers for cancer prognosis and therapy response, paving the way for personalized treatment strategies. The structure of the thesis is outlined to guide the reader through the sequential chapters and sections that compose this research work. Chapter two presents a comprehensive literature review, synthesizing existing knowledge on miRNAs in cancer progression and therapy resistance. Key findings from previous studies are analyzed to identify common miRNA signatures associated with aggressive tumor phenotypes and treatment resistance. The chapter highlights the diverse roles of miRNAs in modulating cancer cell proliferation, invasion, and metastasis, emphasizing their potential as therapeutic targets. Chapter three details the research methodology employed in this study, encompassing experimental design, sample collection, and data analysis procedures. The methodology section describes the cell culture models, miRNA profiling techniques, and bioinformatics tools utilized to characterize miRNA expression patterns in cancer cells. Various in vitro and in vivo assays are performed to validate the functional significance of candidate miRNAs in cancer progression and therapy resistance. Chapter four presents a detailed discussion of the research findings, elucidating the molecular mechanisms through which specific miRNAs regulate key oncogenic pathways in cancer cells. The results reveal novel insights into the crosstalk between miRNAs and target genes involved in tumor growth, angiogenesis, and immune evasion. The implications of these findings for developing targeted therapies and predictive biomarkers are discussed within the context of precision medicine. Chapter five concludes the thesis by summarizing the key findings, highlighting the major contributions to the field of cancer biology. The significance of miRNAs as diagnostic and prognostic markers in cancer progression is underscored, emphasizing the potential clinical applications of miRNA-based therapeutics. Future directions for research are proposed to further explore the therapeutic potential of miRNAs in overcoming therapy resistance and improving patient outcomes in cancer treatment. In conclusion, this thesis provides a comprehensive investigation into the role of miRNAs in cancer progression and therapy resistance, shedding light on the intricate regulatory networks that drive tumor development. The findings offer new insights into the molecular mechanisms underlying cancer pathogenesis and open avenues for developing innovative therapeutic strategies targeting miRNAs in cancer therapy.
