Each point represents the mean ± S.E. of at least three independent experiments. (B) 3T3-L1 adipocytes were transfected with control (Luc), SMRT, NCoR, or PPARγ siRNA. 24 h post transfection, cells were treated with vehicle (Control), 1 µM Rosi (Rosi), 10 ng/ml TNFα (TNFα), or both (Rosi+TNFα) for additional 24 h. Glycerol released into the media and protein concentrations of cell lysate were determined as described in Materials and Methods .

Figure Lengend Snippet: (A) 3T3-L1 adipocytes were treated with DMSO, 660 nM TSA, 20 µM SAHA, 10 µM MS275, or 5 µM MC1568 for 24 h.

Figure Lengend Snippet: (A and B) 3T3-L1 adipocytes were pretreated with vehicle (DMSO) or 660 nM TSA, together with or without 1 µM Rosi (Rosi) for 24h. Cells were then treated with or without 10 ng/ml TNFα for 30 min. Cellular proteins were solubilized and subjected to SDS-PAGE and Western analysis with the indicated antibodies. Representative immunoblots and quantification data from five independent experiments are shown in 5A and B, respectively. (C) ERK phosphorylation correlates highly with lipolysis in the treatments of Rosi, TNFα, or both in the presence or absence of TSA, as shown by fitting with linear regression. Individual values were obtained from the experiments described in Figures. 1 and 7B.

Figure Lengend Snippet: Time course of LPS-induced TNF-α in serum in Dutch belted rabbits primed with TSST-1. Groups of three rabbits were injected with 10.0 ng (i.v.) of TSST-1 (primed)/kg or an equivalent volume of PBS (unprimed). All rabbits were injected with LPS (10 μg/kg [i.v.]) 12 h later. Control rabbits injected with 5 μg of TSST-1 and PBS/kg 12 h later did not develop detectable levels of TNF-α. (∗, P ≤ 0.05).

Figure Lengend Snippet: Direct comparison of LPS-induced TNF-α in serum in mice and rabbits primed with TSST-1. Groups of three BALB/c-AnNCr mice and three Dutch belted rabbits were injected with TSST-1 at doses of 200 μg/kg (i.p.) or 10.0 ng/kg (i.v.), respectively. After 12 h, mice and rabbits were injected with LPS at doses of 400 μg/kg (i.p.) or 10 μg/kg (i.v.), respectively. TNF-α activity in serum was measured at 2 h postinjection of LPS in both species. The levels of TNF-α due to LPS alone were calculated from previous time course studies with the same mice and rabbits. Injection of TSST-1 alone did not induce detectable levels of TNF-α in serum in control animals. The mean peak TNF-α level induced by TSST-1 plus LPS in mice did not significantly differ from that measured in rabbits.
