Objective To express mouse peroxisome proliferator activated receptor γ2 (mPPARγ2) in NIH3T3 fibroblasts mediated by the recombinant retrovirus and study its *** The mPPARγ2 gene was subcloned into retrovirus vector pGCEN to generate the recombinant pGCEN/mPPARγ2. Then it was packaged into PA317 cells and selected with G418. Viral supernatants were harvested and then used to infect NIH3T3 fibroblasts. PPARγ activator 5,8,11,14-eicosatetraynoic acid (ETYA) was used to induce the mPPARγ2-expressing NIH3T3 cells into adipocyte *** The recombinant retrovirus pGCEN/mPPARγ2 was constructed, and the higher titers of the viral supernatants were obtained. mPPARγ2 was expressed in NIH3T3 cells mediated by the recombinant retrovirus. Lipid accumulation obviously existed in these induced adipocytes which morphologically resembled mature adipocytes in vivo and expressed tissue specific adipocyte P2 (AP2) and Leptin *** An adipocyte differentiation model in vitro was successfully established. The work is the basis for further research on the molecular mechanism of adipocyte differentiation induced by PPARγ2.

OBJECTIVE: To report the clinical characteristics, biochemical profiles, diagnosis and treatment of one Chinese pedigree with glucocorticoid-remediable aldosteronism (GRA) and to study its molecular mechanism. METHODS: Plasma and urinary aldosterone, cortisol and plasma renin activities were dynamically tested and diagnostic therapy with dexamethasone was undergone in 3 affected subjects. Long-distance PCR as well as DNA sequencing were applied to detect the fusion gene in this pedigree. RESULTS: In this GRA pedigree, there were 4 affected subjects who had hypertension, hypokalemia and low basic and provoked renin activity. Three patients were given dexamethasone treatment, and had a significant decrease in plasma aldosterone concentrations (PACs) (from 192 +/- 9 ng/L to 87 +/- 7ng/L, P
