Investigating the role of miRNA in regulating gene expression in cancer cells

Thesis Abstract

Abstract
MicroRNAs (miRNAs) are small non-coding RNA molecules that play a crucial role in post-transcriptional gene regulation. In cancer cells, dysregulation of miRNAs has been implicated in the development and progression of various types of cancers. This study aimed to investigate the specific role of miRNAs in regulating gene expression in cancer cells, with a focus on understanding the underlying mechanisms and potential implications for cancer therapy. The research began with a comprehensive review of the literature on miRNAs and their involvement in cancer. The literature review highlighted the importance of miRNAs in cancer biology and their potential as diagnostic and therapeutic targets. The review also identified gaps in knowledge regarding the specific mechanisms by which miRNAs regulate gene expression in cancer cells. The research methodology employed in this study included both in vitro and in silico approaches. Cancer cell lines were used to investigate the expression levels of specific miRNAs and their target genes. In silico analysis was performed to predict potential miRNA-target interactions and elucidate the regulatory networks involved in cancer cell gene expression. The findings of this study revealed that several miRNAs were differentially expressed in cancer cells compared to normal cells. Furthermore, specific miRNAs were identified to target key genes involved in cancer progression, highlighting their potential as therapeutic targets. The in silico analysis provided insights into the complex regulatory networks controlled by miRNAs in cancer cells. The discussion of the findings delved into the implications of these results for cancer research and therapy. The study elucidated the role of miRNAs as critical regulators of gene expression in cancer cells and provided a deeper understanding of the mechanisms underlying their dysregulation in cancer. The potential for targeting specific miRNAs as a strategy for cancer treatment was also discussed. In conclusion, this research contributes to the growing body of knowledge on the role of miRNAs in cancer biology. The findings underscore the importance of miRNAs in regulating gene expression in cancer cells and suggest potential avenues for the development of novel therapeutic strategies targeting miRNAs. Further research in this area is warranted to fully exploit the therapeutic potential of miRNAs in cancer treatment.
