Exploring the role of microRNAs in regulating gene expression in cancer cells

Thesis Abstract

Abstract
MicroRNAs (miRNAs) are small non-coding RNA molecules that play crucial roles in post-transcriptional gene regulation. In recent years, there has been a growing interest in understanding the impact of miRNAs on gene expression in various diseases, including cancer. This thesis aims to explore the role of miRNAs in regulating gene expression in cancer cells, focusing on how dysregulation of miRNAs can contribute to tumorigenesis and cancer progression. The introduction provides a comprehensive overview of miRNAs, their biogenesis, and mechanisms of gene regulation. The background of the study highlights the significance of miRNAs in cancer biology and the potential implications for cancer therapy. The problem statement emphasizes the need to unravel the complex interactions between miRNAs and their target genes in cancer cells. The objectives of the study include identifying key miRNAs involved in cancer development, elucidating their target genes, and understanding the molecular mechanisms underlying miRNA-mediated gene regulation. The limitations of the study are discussed, such as the challenges in accurately predicting miRNA targets and the heterogeneity of cancer cell populations. The scope of the study is defined in terms of the specific cancer types and experimental approaches that will be employed. The significance of the study lies in its potential to uncover novel biomarkers for cancer diagnosis and prognosis, as well as therapeutic targets for precision medicine. The structure of the thesis is outlined, including the chapters on literature review, research methodology, discussion of findings, and conclusion. The literature review synthesizes current knowledge on miRNA dysregulation in cancer, highlighting the roles of specific miRNAs in different cancer types. The research methodology section describes the experimental techniques used to study miRNA expression profiles, target gene validation, and functional assays in cancer cells. In the discussion of findings, the results of miRNA profiling and target gene analysis are presented and interpreted in the context of cancer biology. The implications of dysregulated miRNAs on key cellular processes, such as cell proliferation, apoptosis, and metastasis, are discussed. In conclusion, this thesis provides valuable insights into the role of miRNAs in regulating gene expression in cancer cells and offers new perspectives on the potential diagnostic and therapeutic applications of miRNAs in cancer. Further research in this area is warranted to fully exploit the clinical utility of miRNAs as biomarkers and targets for cancer treatment.
