Project Overview: Examine the role of microRNAs in regulating gene expression in cancer cells and explore their potential as therapeutic targets

Cancer is a complex disease characterized by uncontrolled cell growth and proliferation, often driven by disruptions in the regulation of gene expression. MicroRNAs (miRNAs) are small non-coding RNAs that play crucial roles in post-transcriptional gene regulation by binding to target messenger RNAs (mRNAs) and either inhibiting their translation or promoting their degradation. In recent years, there has been growing interest in understanding the role of miRNAs in cancer development and progression, as well as their potential as therapeutic targets.

Research Objectives

The primary objective of this project is to examine the role of miRNAs in regulating gene expression in cancer cells. This will involve a comprehensive analysis of the dysregulated miRNA expression patterns in various types of cancer, as well as their specific target genes and pathways. By elucidating the molecular mechanisms by which miRNAs contribute to cancer pathogenesis, we aim to gain insights into potential therapeutic strategies targeting these molecules.

Methodology

This project will involve a combination of bioinformatic analyses, cell culture experiments, and animal models to investigate the functional significance of specific miRNAs in cancer. High-throughput sequencing technologies will be used to profile miRNA expression profiles in cancer cells, followed by computational prediction algorithms to identify their target genes. Functional assays, such as luciferase reporter assays and CRISPR/Cas9-mediated gene editing, will be employed to validate the interactions between miRNAs and their targets.

In addition, the therapeutic potential of targeting dysregulated miRNAs in cancer will be explored using in vitro and in vivo models. Synthetic miRNA mimics or inhibitors will be used to modulate the levels of specific miRNAs in cancer cells, followed by assessments of their effects on cell proliferation, migration, and invasion. Furthermore, nanoparticle-based delivery systems will be utilized to deliver miRNA-targeting agents in animal models to evaluate their efficacy and safety.

Significance and Expected Outcomes

Understanding the role of miRNAs in cancer gene regulation has the potential to uncover novel biomarkers for cancer diagnosis and prognosis, as well as identify new therapeutic targets for drug development. By elucidating the mechanisms by which miRNAs contribute to cancer progression, this project aims to provide valuable insights that could lead to the development of more effective and personalized cancer therapies.

Overall, this project will contribute to advancing our knowledge of cancer biology and may ultimately lead to the development of innovative treatment strategies that exploit the regulatory functions of miRNAs in cancer cells.
