Abstract:
Determining the relationships between miRNA expression, target genes, and cancer development is critical to cancer research. The possibility of correlating miRNA expression with plant or artificial ones provides prerequisites for cancer treatment. Based on the broad database of human miRNA expression for all cancer types, we grade human miRNAs by their expression level. The identified deficient miRNAs are compared with their target genes for coincidences in their expression directions. The replacement of human miRNAs is proposed to be implemented, using plant miRNAs closest to the human-deficient ones. Such plant substitutes are identified by analyzing the average complementarity of all human under-expressed miRNAs. It was established that the number of downregulated miRNAs is almost 2.5 times greater than that of upregulated miRNAs. There is no significant correlation between the expression of miRNA and genes, implying many other expression regulation mechanisms exist. Working on the organization of experimental verification of the obtained statistical studies, we present significant regularities that provide grounds for considering some plant microRNAs as possible means of compensating for insufficient expression of regulatory microRNAs in humans and animals in a wide range of oncological diseases.
Insights
This study identifies plant microRNAs (miRNAs) that can potentially replace deficient human miRNAs in cancer treatment. Findings suggest plant miRNAs may compensate for downregulated regulatory miRNAs in various oncological diseases.
Area of Science:
- Oncology
- Molecular Biology
- Bioinformatics
Background:
- MicroRNA (miRNA) expression is crucial for understanding cancer development.
- Identifying correlations between miRNA expression, target genes, and cancer is vital for research.
- Plant-derived miRNAs offer potential therapeutic avenues for cancer treatment.
Purpose of the Study:
- To grade human miRNAs by expression levels across all cancer types.
- To identify potential plant-based miRNA substitutes for deficient human miRNAs.
- To explore the feasibility of using plant miRNAs for compensating regulatory miRNA deficiencies in oncological diseases.
Main Methods:
- Analysis of a comprehensive database of human miRNA expression.
- Comparison of downregulated human miRNAs with their target genes.
- Identification of plant miRNAs with high complementarity to under-expressed human miRNAs.
Main Results:
- Downregulated miRNAs were found to be 2.5 times more prevalent than upregulated miRNAs.
- No significant direct correlation was observed between miRNA and gene expression.
- Plant miRNAs were identified as potential substitutes for deficient human miRNAs.
Conclusions:
- Plant miRNAs show promise in compensating for insufficient regulatory miRNA expression in human and animal cancers.
