Thesis Abstract

Abstract
MicroRNAs (miRNAs) are small non-coding RNAs that play crucial roles in gene regulation and have emerged as key players in cancer development and progression. This thesis aims to explore the intricate mechanisms by which miRNAs influence cancer initiation, metastasis, and response to therapy. The study delves into the dysregulation of miRNAs in various cancer types and their impact on oncogenic pathways. Through a comprehensive literature review, ten critical aspects of miRNA involvement in cancer are analyzed, shedding light on their potential as diagnostic markers and therapeutic targets. The research methodology section outlines the experimental approaches used to investigate miRNA expression profiles, target genes, and functional implications in cancer cell lines and patient samples. Various techniques, including next-generation sequencing, qRT-PCR, and bioinformatics analyses, are employed to decipher the complex miRNA-mediated regulatory networks in cancer. The results obtained from these analyses are discussed in detail in the findings chapter, highlighting significant miRNA alterations associated with different stages of cancer progression. The discussion section critically evaluates the implications of the findings, emphasizing the potential of miRNAs as biomarkers for early cancer detection and prognosis prediction. Furthermore, the therapeutic targeting of dysregulated miRNAs holds promise for developing novel treatment strategies to combat cancer progression. The limitations of the study are acknowledged, including the challenges in identifying specific miRNA targets and elucidating their precise functions in cancer biology. In conclusion, this thesis underscores the importance of miRNAs in orchestrating the complex molecular events that drive cancer development and progression. By elucidating the role of miRNAs in cancer pathogenesis, this research contributes to a deeper understanding of the underlying mechanisms and paves the way for future translational applications in precision medicine. The significance of this study lies in its potential to impact clinical practice by providing insights into personalized cancer treatment strategies based on miRNA signatures. Ultimately, this work highlights the pivotal role of miRNAs as key regulators of oncogenesis and emphasizes their therapeutic potential in combating cancer progression.
