AB  - We investigated the effects of centrally administered orexigenic hormone ghrelin on energy imbalance-induced inflammation. Rats were subjected for four weeks to three different dietary regimes: normal (standard food), high-fat (standard food with 30% lard) or food-restricted (70%, 50%, 40% and 40% of the expected food intake in 1st, 2nd, 3rd and 4th week, respectively). Compared to normal-weight controls, starved, but not obese rats had significantly higher levels of proinflammatory cytokines (TNF, IL-1 beta, IFN-gamma) in the blood. When compared to normally fed animals, the hearts of starved and obese animals expressed higher levels of mRNAs encoding proinflammatory mediators (TNF, IL-1 beta, IL-6, IFN-gamma, IL-17, IL-12, iNOS), while mRNA levels of the anti-inflammatory TGF-beta remained unchanged. Intracerebroventricular (ICV) injection of ghrelin (1 mu g/day) for five consecutive days significantly reduced TNF, IL-1 beta and IFN-gamma levels in the blood of starved rats, as well as TNF, IL-17 and IL-12p40 mRNA expression in the hearts of obese rats. Conversely, ICV ghrelin increased the levels of 1FN-gamma, IL-17,1L-12p35 and IL-12p40 mRNA in the heart tissue of food-restricted animals. This was associated with an increase of immunosuppressive ACTH/corticosterone production in starved animals and a decrease of the immunostimulatory adipokine leptin both in food-restricted and high-fat groups. Ghrelin activated the energy sensor AMP-activated protein kinase (AMPK) in the hypothalamus and inhibited extracellular signal-regulated kinase (ERK) in the hearts of obese, but not starved rats. Therefore, central ghrelin may play a complex role in energy imbalance-induced inflammation by modulating HPA axis, leptin and AMPK/ERK signaling pathways. (C) 2011 Elsevier Inc. All rights reserved.

AB  - The peroxisome proliferator-activated receptor gamma (PPAR gamma) is a gene candidate for the onset of type 2 diabetes mellitus (T2DM). We investigated the association of the PPAR gamma Pro12Ala gene with the onset of T2DM for the first time in the Serbian population. The study population consisted of 197 controls and 163 T2DM patients. The 12Ala allele tended to be more frequent in the group of T2DM patients (0.11) compared to the control subjects (0.09). The results from this study indicate that the PPAR gamma(2) 12Ala allele presents a non-significant risk factor for T2DM development in the Serbian population.

AB  - We investigated the effect of compound C, a well-known inhibitor of the intracellular energy sensor AMP-activated protein kinase (AMPK), on proliferation and viability of human U251 and rat C6 glioma cell lines. Compound C caused G(2)/M cell cycle block, accompanied by apoptotic glioma cell death characterized by caspase activation, phosphatidylserine exposure and DNA fragmentation. The mechanisms underlying the pro-apoptotic action of compound C involved induction of oxidative stress and downregulation of antiapoptotic molecule Bcl-2, while no alteration of pro-apoptotic Bax was observed. Compound C diminished AMPK phosphorylation and enzymatic activity, resulting in reduced phosphorylation of its target acetyl CoA carboxylase. AMPK activators metformin and AICAR partly prevented the cell cycle block, oxidative stress and apoptosis induced by compound C. The small interfering RNA (siRNA) targeting of human AMPK mimicked compound C-induced G(2)/M cell cycle arrest, but failed to induce oxidative stress and apoptosis in U251 glioma cells. In conclusion, our data indicate that AMPK inhibition is required, but not sufficient for compound C-mediated apoptotic death of glioma cells. (c) 2009 Elsevier Inc. All rights reserved.
