Thesis Overview

The project titled "Investigating the Role of MicroRNAs in Cancer Progression and Therapy Resistance" aims to explore the intricate involvement of MicroRNAs in the progression of cancer and the development of resistance to therapeutic interventions. MicroRNAs are small non-coding RNA molecules that play crucial roles in regulating gene expression at the post-transcriptional level. In cancer, dysregulation of MicroRNAs has been implicated in various aspects of tumorigenesis, including tumor growth, metastasis, and resistance to chemotherapy and targeted therapies. This research project will delve into the specific MicroRNAs involved in promoting cancer progression and therapy resistance across different cancer types. By investigating the expression profiles of these MicroRNAs in cancer cells and tissues, the study aims to elucidate their functional roles in driving tumorigenesis and mediating resistance to standard cancer treatments. Understanding the mechanisms by which these MicroRNAs contribute to cancer progression and therapy resistance is crucial for developing novel therapeutic strategies that target these molecules to improve patient outcomes. Furthermore, the project will employ advanced molecular biology techniques, bioinformatics analyses, and in vitro and in vivo experimental models to characterize the regulatory networks and signaling pathways modulated by these MicroRNAs in cancer cells. By integrating multi-omics data and functional studies, the research aims to unravel the complex interactions between MicroRNAs and their target genes, as well as their impact on key cellular processes involved in cancer progression and therapy response. Overall, this research overview underscores the significance of investigating the role of MicroRNAs in cancer biology and therapy resistance. By unraveling the molecular mechanisms underlying the dysregulation of MicroRNAs in cancer cells, this project seeks to provide valuable insights into novel therapeutic targets and biomarkers for improving cancer treatment efficacy and patient outcomes.
