OBJECTIVE: To determine the bioinformatical characteristics of differential gene expression in patients with chronic superficial gastritis (CSG) with the Pi-deficiency syndrome (PDS) and those of the non-Pi-deficiency syndrome (non-PDS), i.e. patients of CSG with Pi-Wei dampnese-heat syndrome and healthy persons.
METHODS: With the BRB-Array Tools software package, original data collection and bioinformatic: analysis of gene arrays were conducted in 6 CSG patients of PDS (CSG-PDS), 6 CSG patients of non-PDS (CSG-nPDS), and 6 healthy volunteers (Normal).
RESULTS: Compared with non-PDS, the gene expressions: in PDS with regards to protein synthesis, energy metabolism, immune reaction and ionic transport tended to be down-regulated, while those concerning secretion, cytoskeleton and ubiquitinization were up-regulated dominantly.
CONCLUSIONS: The two kinds of samples, CSG-PDS/Normal and CSG-PDS/CSG-nPDS, have their respective gene expression profiles with different characteristics. Gene expression profile has certain referential significance in syndrome classification.
