Bioinformatics Evaluation and Signaling Network Analysis of Total Target mRNA and Related SNP Function in People with Gastric Cancer

Stomach cancer is the fourth most common cancer and the second leading cause of cancer death in the world. In addition to significant costs, it imposes many problems on families that is a proper justification for identifying related biomarkers.

The miRBASE website was used to find bioinformatics information. In addition, mirWALK and miRNASN databases were searched to find miRNAs information. To find cancer pathways, the DAVID and KEGG databases were adopted.

The studies conducted on the first pathway reported that microRNA and has-miR-10a-3p, through binding to rs1049216 in the CASP3 gene, by exerting an inhibitory effect on this gene, prevents the development of cancer. In the second pathway, microRNA and has-miR-296-3p, by binding to rs1564483 in the BCL2 gene, by exerting an inhibitory effect on this gene, causes cancer. In the third pathway, microRNA and has-miR-194-3p, through binding to rs7177 in the CCND1 gene, by exerting an inhibitory effect on this gene, prevents the development of cancer.

In this research, cancer pathways involved in cancer were predicted. By finding three SNPs on specific regions of the three above-said genes, we found that these SNPs can be the cause of stomach cancer and can be introduced as biological biomarkers.
