Thesis Overview

The project titled "Exploring the Role of MicroRNAs in Cancer Progression and Potential Therapeutic Targets" focuses on investigating the intricate involvement of microRNAs in cancer progression and their potential as therapeutic targets for the treatment of cancer. This research aims to shed light on the underlying mechanisms by which microRNAs contribute to cancer development, metastasis, and drug resistance, as well as to explore how targeting specific microRNAs could offer novel therapeutic strategies for combating cancer. MicroRNAs are small non-coding RNA molecules that play crucial roles in regulating gene expression at the post-transcriptional level. Dysregulation of microRNAs has been implicated in various aspects of cancer biology, including cell proliferation, apoptosis, invasion, and metastasis. By targeting specific mRNAs, microRNAs can either promote or suppress tumorigenesis, making them attractive candidates for cancer therapy. The research will begin with a comprehensive literature review to provide a thorough understanding of the current knowledge regarding the roles of microRNAs in different types of cancer. This review will cover the mechanisms by which microRNAs influence cancer progression, the identification of dysregulated microRNAs in various cancer types, and the potential of microRNAs as diagnostic and prognostic biomarkers. Subsequently, the project will delve into the research methodology, detailing the experimental approaches and techniques that will be employed to investigate the expression patterns and functional roles of specific microRNAs in cancer cells. This will involve cell culture studies, molecular biology techniques such as qRT-PCR and Western blotting, as well as bioinformatics analysis to identify potential microRNA targets and signaling pathways involved in cancer progression. The findings of this research will be presented and discussed in detail in Chapter Four, highlighting the key microRNAs that are dysregulated in cancer and their impact on tumor growth, metastasis, and drug resistance. The discussion will also explore the therapeutic potential of targeting these microRNAs using various strategies, such as antisense oligonucleotides, small molecule inhibitors, or nanotechnology-based delivery systems. In conclusion, the project will summarize the main findings and their implications for cancer research and therapy in Chapter Five. The research outcomes are expected to provide valuable insights into the roles of microRNAs in cancer progression and offer new avenues for the development of targeted therapies that exploit the unique regulatory functions of microRNAs in cancer cells. Ultimately, this research aims to contribute to the growing body of knowledge on microRNAs in cancer and pave the way for innovative therapeutic approaches to improve cancer treatment outcomes.
