Correlation Analysis of miRNA, mRNA and Degradomics

The key point of combined analysis of miRNA, mRNA and degradomics is the results of tumor degradation analysis. The miRNA sequence used in tumor degradation analysis is all the miRNA, identified by mRNA sequencing. The database compared with the database is the sequence obtained by transcriptome sequencing. The relationship pair information between miRNA and target genes can be obtained by degradation sequencing. Then through the miRNA- target gene network regulation map, we can directly show that miRNA regulates multiple target genes and the same target gene is regulated by multiple miRNA. Through the integrated analysis of these three data, we can explore the regulatory mechanism involved in the process of tumor gene expression.

The purpose of our research.

1. Obtaining the "panorama" of the expression profile is beneficial to the omni-directional analysis and study of the expression of miRNA, mRNA and Degradomics in tumors.

2. Mining common and unique sequence analysis among tumor samples;

3. Compared with related databases, classification annotation non-coding RNA;

GO enrichment histogram.

Among all the selected miRNA target genes, the corresponding GO of these genes is annotated as follows.Molecular Function, Biological Process and Cellar Component.It is divided into three categories, and the GO function in each category is changed from the number of target genes annotated to.Sort from high to low, and map, Abscissa is the classification of GO, ordinate is the target base. Because of the percentage, the target genes annotated to the same GO can be seen visually.

KEGG pathway diagram

Display and description of Pathway road map: red indicates that it is annotated to a certain ko node and is up-regulated.Genes that are significantly differentially expressed. Blue or purple represent those that are annotated to a ko node and down-regulated. Author of differentially expressed genes. The four digits in the box indicate the EC numbers of various enzymes; hollow circle. Circles represent small molecular compounds; solid arrows indicate the direction of biochemical reactions; dotted arrows connect.


Network Regulation Analysis of miRNA-mRNA.

MiRNA- target gene network regulation map can directly show that miRNA regulates multiple target genes and the same target gene is regulated by multiple miRNA. Researchers can determine the miRNA- target gene pairs of concern according to their own research needs for follow-up experimental verification.
