Heat Shock Protein 90 Alpha, Lass B Member 1: a Key Regulative Gene of Monitoring Duodenal Tumor for Obesity Induced by High-Fat Diet.

BACKGROUND: Effective methods of preventing and treating duodenal carcinoma, especially cancer induced by obesity (resulting from a high-fat diet) remains a longstanding challenge in medicine. METHODS: With regard to the objective, key genes were explored in the evolutional process in a group of normal, obese (high-fat diet), and duodenal tumor mice. Here, 23 genes were selected by the bioinformatics method. In order to correct the result, verification experiments were performed twice through online analysis. RESULTS: Finally, heat shock protein 90 alpha class B member 1, enriched in inflammation, tumors and steroid hormones-related pathways, was the statistically different gene in the evolutional process. CONCLUSIONS: This work provided a new perspective to understand the evolutional process in a group of normal, obese (high-fat diet), and duodenal tumor mice and a potential target gene for monitoring duodenal tumors for normal individuals especially for obesity induced by high-fat diet.
