[Regulation of chromium on gene expression of skeletal muscles in diabetic rats].

Objective: To study the regulation of chromium on gene expression related to metabolism of skeletal muscles in diabetic rats.

Methods: Male Wistar rats were assigned to three groups: normal control group (NC), alloxan-induced diabetic control group (DM), and DM with chromium supplementation group (DM + Cr). 200 microg Cr/kg bw perday was supplemented orally for 60 days.

[Effects of chromium supplementation on IRS-1 expression of skeletal muscle in diabetic rats].

Objective: To study the effects of chromium supplementation on related gene expression to metabolism of skeletal muscles in diabetic rats.

Methods: cDNA fragments from the out related research were cloned, sequenced and its comparalarity analysis has been done. The RT-PCR were made using the primers designed according to the sequence of cDNA.
