ABSTRACTGene expression studies of subcutaneous adipose tissue may help to better understand the mechanisms behind body fat changes in HIV-infected patients who initiate antiretroviral therapy (ART). Here, we evaluated early changes in adipose tissue gene expression and their relationship to fat changes in ART-naive HIV-infected patients randomly assigned to initiate therapy with emtricitabine/tenofovir plus efavirenz (EFV) or ritonavir-boosted lopinavir (LPV/r). Patients had abdominal subcutaneous adipose tissue biopsies at baseline and week 16 and dual-energy-X-ray absorptiometry at baseline and weeks 16 and 48. mRNA changes of 11 genes involved in adipogenesis, lipid and glucose metabolism, mitochondrial energy, and inflammation were assessed through reverse transcription-quantitative PCR (RT-qPCR). Additionally, correlations between gene expression changes and fat changes were evaluated. Fat increased preferentially in the trunk with EFV and in the limbs with LPV/r (P< 0.05). After 16 weeks of exposure to the drug regimen, transcripts ofCEBP/A,ADIPOQ,GLUT4,LPL, andCOXIVwere significantly down-regulated in the EFV arm compared to the LPV/r arm (P< 0.05). Significant correlations were observed betweenLPLexpression change and trunk fat change at week 16 in both arms and betweenCEBP/AorCOXIVchange and trunk fat change at the same time point only in the EFV arm and not in the LPV/r arm. When combined with emtricitabine/tenofovir as standard backbone therapy, EFV and LPV/r induced differential early expression of genes involved in adipogenesis and energy metabolism. Moreover, these mRNA expression changes correlated with trunk fat change in the EFV arm. (This was a substudy of a randomized clinical trial [LIPOTAR study] registered atClinicalTrials.govunder identifier NCT00759070.)

Дисбаланс в секреции адипокинов жировой тканью при ожирении может играть роль в развитии сердечно-сосудистых заболеваний. Нами было проведено исследование уровня экспрессии генов адипонектина и оментина-1 в жировой ткани у лиц с ожирением и ишемической болезнью сердца (ИБС). Показано, что сниженные концентрация в сыворотке крови и экспрессия гена адипонектина в подкожной жировой ткани могут вносить вклад в развитие ИБС при ожирении. ИБС ассоциирована с низкой концентрация оментина-1 в сыворотке крови. Imbalance in the secretion of adipose tissue adipokines may play a role in the development of cardiovascular diseases associated with obesity. Investigation of adiponectin and omentin-1 genes expression levels in adipose tissue was conducted in patients with obesity and coronary artery disease (CAD). Our study has shown that reduced adiponectin serum concentration and subcutaneous adipose tissue gene expression may contribute to CAD development. CAD is associated with a low serum omentin-1 concentration.
