Background and aims: MEHMO is an X-linked syndrome comprising Mental retardation, Epilepsy, Hypogenitalism, Microcephaly and Obesity. It is caused by a damaging p.Ile465Serfs frameshift mutation in EIF2S3 that encodes the □ subunit of eukaryotic translation initiation factor 2 (eIF2), essential for protein synthesis and regulation of the integrated stress response. Patients with this EIF2S3 mutation also have neonatal hypoglycemia, early onset insulin-...

Adult GH deficiency (GHD) is associated with prediabetes and low levels of GH are found in obesity. We hypothesized that zinc-α2-glycoprotein (ZAG), a novel adipokine reduced in obesity, is regulated by GH. ZAG serum and adipose tissue expression were measured in three study populations: i) cachectic (BMI=19.3±0.5 kg/m2), lean/overweight (BMI=26.0±0.5 kg/m2) and obese (BMI=36.0±1.6 kg/m2) patients with chronic obstructive pu...

The role of adipokines and inflammatory cytokines of adipose tissue for development of the growth hormone deficiency (GHD)-related metabolic derangements has not yet been completely understood. Therefore, we screened the protein level of 120 adipokines in subcutaneous adipose tissue (ScAT) of patients with GHD in adulthood.Subjects and methods: Sixteen GHD (10M/6F) with BMI 27±1.0 kg/m2, age 30±2 yrs and sixteen controls matched for ...

Growth hormone deficiency (GHD) in adults seems to predispose to insulin resistance (IR). Development of GHD related IR could be associated with adipose tissue (AT) derived signals. To investigate the nature of this pathological regulation we 1) measured gene expressions for leptin, adiponectin, TNFalpha, IL-6, 11beta HSD1, SREBP, PPARgamma in the AT of untreated GHD adults, and 2) assessed effect of euglycemic hyperinsulinemia (HI) at the gene level.Met...
