Intrauterine growth retardation (IUGR) has been linked to metabolic syndrome including insulin resistance, and overexpression of suppressors of cytokine signaling (SOCSs) proteins is thought to be associated with increased whole-body insulin sensitivity. The insulin-resistant IUGR rat model was established by maternal food restriction (about 30% of the normal rats). The weight, length, and homeostasis model assessment of insulin resistance (HOMA-IR) of IUGR-born rats was higher than the control group. Insulin receptor substrate (IRS)-1 expression decreased, whereas SOCS-1 and SOCS-3 increased in the skeletal muscle of IUGR rats compared with the control group. The recombination plasmids PGPU6/GFP/Neo-SOCS-1small hairpin RNA (shRNA) and PGPU6/GFP/Neo-SOCS-3shRNA were transfected into skeletal muscle cells, and the shRNAs efficiently inhibited the expression of SOCS-1 and SOCS-3. Insulin-stimulated glucose transporter-4 (GLUT4) translocation was also dramatically increased. In conclusion, these data provide additional information on the mechanism of insulin resistance associated with IUGR. Down-regulation of SOCS-1 and SOCS-3 ameliorates the capacity of glucose transport and provides a potential gene therapy approach to managing metabolic syndrome.

Diseases associated with metabolic syndromes are of major concern in developed countries. Nonalcoholic steatohepatitis (NASH) is one of the manifestations of metabolic syndrome in the liver. Previous studies have shown that NASH is also caused by malnutrition. In the present study, a case of malnutrition-associated NASH in a 66-year-old female with anorexia nervosa is reported. The patient had a body mass index (BMI) of only 11.1 kg/m2 and serum alanine aminotransferase levels of 1,495 IU/l. Steatohepatitis with fibrosis was confirmed by percutaneous liver needle biopsy. Total parenteral nutrition was conducted at first, followed by the administration of Stronger Neo-Minophagen C (a glycyrrhizin-containing preparation), ursodeoxycholic acid and prednisolone. The abnormal elevation of aminotransferase levels of the patient was prolonged and total bilirubin levels increased. Pioglitazone (15 mg/day), which has been identified to be effective for nonalcoholic steatohepatitis, was then administered. This resulted in marked reductions in aminotransferase and bilirubin levels within three months. Histological improvement of the liver was also confirmed by percutaneous liver needle biopsy after one year. The observations in the present case suggest that pioglitazone may be useful for the treatment of malnutrition-associated NASH.
