Technical Abstract: Syrian hamsters fed a high fat (HF) diet similar in fat content to the American diet become insulin resistant (IR). We have shown earlier that replacing cellulose in this HF diet with hydroxypropylmethylcellulose (HPMC) significantly decreases the incidence of IR. HPMC significantly reduced the glucose infusion rate, fasting plasma insulin, plasma lipids, overall fat distribution in non-adipose tissues, and the cell size of adipose tissues. The underlying mechanisms of these beneficial physiological effects are unknown. A cDNA microarray, constructed from Chinese hamster ovary cells, was used to analyze gene expression in liver tissues from hamsters fed the HF or the HF with HPMC diets. Genes related to fat metabolism, glucose metabolism, insulin metabolism, inflammation and glucose transport, were differentially expressed between the two groups. These results indicate that HPMC may prevent the cellular oxidative damage leading to diabetes by normalizing fat metabolism.
