Down-regulation of TP53 Is a Highlighted Molecular Event in Gastric Ulcer

Gastric ulcer as an acid related gastrointestinal disease is known as a one of the most public gastrointestinal disorders.

Explore the crucial dysregulate proteins and biochemical pathways in gastric ulcer is the main aim of this projects.

Number of 100 proteins from STRING database were analyzed by cytoscape and its applications to find the central proteins and also the related biochemical pathways. Action map analysis was applied to explore regulatory relationship between the critical proteins.

Common results of network analysis and gene ontology revealed that IL6, ALB, TNF, INS, IL1B, IL10, TP53, CXCL8, and PTGS2 are the highlighted related proteins in gastric ulcer. Six clusters of biochemical pathways including “Response to external stimulus”, “multicellular organismal process”, “regulation of biological quality”, “cellular response to stimulus”, “cellular response to chemical stimulus”, and “transport” were identified as the dysregulated pathway in patients.

It seems that down-regulation of TP53 by IL2, PTGS2, and TNF is a main process that occurs in patients.
