MicroRNAs (miRNAs) fine-tune protein expression and regulate cell functions. Aberrant miRNA regulation is linked to cancer, making them promising biomarkers and therapeutic targets for molecular-targeted cancer therapy.
Area of Science:
- Biochemistry
- Molecular Biology
- Genetics
Background:
- MicroRNAs (miRNAs) are short, single-stranded RNAs regulating protein expression by modifying mRNA translation.
- These molecules are crucial for cellular processes like development, growth, and apoptosis.
- Dysregulated miRNA expression is implicated in the pathogenesis of various diseases, particularly cancer.
Purpose of the Study:
- To review the roles of miRNA-protein interactions in cancer progression.
- To explore the potential of miRNAs as cancer biomarkers and therapeutic targets.
- To discuss future applications of miRNA-based molecular-targeted therapy.
Main Methods:
- Literature review of studies on miRNA function in cancer.
- Analysis of research on miRNA-protein and miRNA-mRNA interactions.
- Synthesis of findings regarding miRNA expression changes in cancer tissues and exosomes.
Main Results:
- Cellular and extracellular miRNA expression changes correlate with cancer prognosis.
- miRNAs directly bind to proteins and mRNAs, influencing cancer progression.
- miRNA-protein systems represent a key regulatory mechanism in cancer.
Conclusions:
- miRNAs are critical regulators of cellular functions and are involved in cancer development.
- Altered miRNA expression patterns serve as potential biomarkers for cancer diagnosis and prognosis.
- miRNA-based strategies offer promising avenues for molecular-targeted cancer therapy.

Tumor Progression
Colon cancer is one of the best-documented examples of tumor progression. Early mutation in the APC gene in colon cells causes a small growth on the colon wall called a polyp. With time, this polyp grows into a benign, pre-cancerous tumor. Further...
