Figure Legend Snippet: Human SGBS adipocytes were pretreated with HT (1 h) (A), OA (48 h) or RSG (24 h) (B) at the concentrations indicated and then either treated with 10 ng/mL TNF-α (black-filled bars), or left untreated (open white bars), for 24 h. Adiponectin levels in the culture medium were determined by ELISA, and expressed as percent of unstimulated control (CTL). Bars represent means ± SD (n = 3). # p <0.05 versus CTL. * p <0.05 versus TNF-α. ** p <0.01 versus TNF-α.
Techniques Used: Enzyme-linked Immunosorbent Assay, Control
Figure Legend Snippet: SGBS cells were pretreated with either HT, OA or cotreated with HT + OA before 10 ng/mL TNF-α stimulation for 24 h. (A) Adiponectin in the culture medium was determined by ELISA, and expressed as percent of unstimulated control (CTL). (B) Adiponectin intracellular protein levels were determined by Western analysis using antibodies against adiponectin. Western analysis under reducing and denaturing condition here reveals the 30 kDa adiponectin monomer. Adiponectin expression was normalized to β-actin, and expressed as percent of unstimulated control (CTL). Data are means ± SD (n = 3). # p <0.05 versus CTL. * p <0.05 versus TNF-α alone. † p <0.05 versus each compound + TNF-α.
Techniques Used: Enzyme-linked Immunosorbent Assay, Control, Western Blot, Expressing
Figure Legend Snippet: SGBS cells were pretreated with either HT, OA or cotreated with HT + OA before 10 ng/mL TNF-α stimulation for 24 h. Adiponectin mRNA levels were determined by qPCR and normalized to 18S RNA. Data are expressed as fold induction over unstimulated control (CTL). Data are means ± SD (n = 3). # p <0.05 versus CTL. * p <0.05 versus TNF-α alone. † p <0.05 versus each compound + TNF-α.
Techniques Used: Control
Figure Legend Snippet: (A) SGBS cells were treated with 1 μmol/L HT, 10 μmol/L OA, or 1 μmol/L RSG in the absence or presence of the PPARγ antagonist GW9662 at 10 μmol/L (GW), and then stimulated with 10 ng/mL TNF-α for 24 h. Adiponectin levels in the culture medium were determined by ELISA, and expressed as percent of unstimulated control (CTL). Data are means ± SD (n = 3). # p <0.05 versus CTL. * p <0.05 versus TNF-α alone. † p <0.05 versus the compound-treated group without GW9662. (B) and (C) SGBS cells were treated with 1 μmol/L HT or 10 μmol/L OA before 10 ng/mL TNF-α stimulation for 24 h. (B) Whole-cell lysates were assayed by Western blotting using antibodies against PPARγ1, PPARγ2, and against β-actin, this last used as a loading control. Total PPARγ1 and PPARγ2 band intensities were normalized to β-actin, and are expressed as percent of unstimulated control (CTL). (C) Nuclear proteins were analyzed for PPARγ DNA-binding activity by ELISA as described in Methods. Data are expressed as percent of unstimulated control (CTL). (D) SGBS cells were treated with 1–10 μmol/L HT, or 10 μmol/L OA, or co-treated with OA + HT before 10 ng/mL TNF-α stimulation for 24 h. PPARγ mRNA levels were determined by qPCR and normalized to 18S RNA. Data are expressed as fold induction over unstimulated control (CTL). Bars represent means ± SD (n = 3). # p <0.05 versus CTL. * p <0.05 versus TNF-α. † p <0.05 versus each compound + TNF-α.

Figure Legend Snippet: SGBS cells were pretreated for 1 h with 10 μmol/L of the JNK inhibitor SP600125 (SP), the ERK1/2 inhibitor PD98059 (PD), or the p38 inhibitor SB203580 (SB), and then stimulated with 10 ng/mL TNF-α for 24 h. Culture media were analyzed for adiponectin by ELISA (A), and whole-cell lysates were assayed by Western blotting using antibodies against adiponectin (B) or PPARγ (C). Adiponectin and PPARγ expression were normalized to β-actin, and expressed as percent of unstimulated control (CTL). Bars represent means ± SD (n = 3). # p <0.05 versus CTL. * p <0.05 versus TNF-α.
Techniques Used: Enzyme-linked Immunosorbent Assay, Western Blot, Expressing, Control
Figure Legend Snippet: SGBS cells were treated with scrambled negative control siRNA (siControl), JNK1 siRNA (siJNK1), JNK2 siRNA (siJNK2), or JNK1 plus JNK2 siRNA, for 72 h. The mRNA expression levels of JNK1 and JNK2 were measured by qPCR, normalized to 18S RNA, and expressed as fold induction over scrambled negative control siRNA (A). JNK1 and JNK2 intracellular protein levels were assayed by Western blotting, normalized to β-actin, and expressed as percent of scrambled negative control siRNA (B). Bars represent means ± SD. # p <0.05 versus siControl. After 72 h of transfection, cells were stimulated with 10 ng/mL TNF-α for further 24 h. Adiponectin mRNA were determined by qPCR (C), while adiponectin intracellular and secreted protein levels were determined by Western analysis (D) and ELISA (E), respectively. Bars represent means ± SD. # p <0.05 versus siControl without TNF-α. * p <0.05 versus siControl with TNF-α.
Techniques Used: Negative Control, Expressing, Western Blot, Transfection, Enzyme-linked Immunosorbent Assay
Figure Legend Snippet: Pre-treatment with HT and OA before TNF-α stimulation prevents JNK activation and restores PPARγ expression and activity and, as a consequence, adiponectin levels. A coherent interpretation of the findings is as follows: upon binding to the cognate receptor, TNF-α induces reactive oxygen species (ROS) production and triggers an inflammatory signaling cascade involving, among others, the activation of JNK, which mediates the degradation of PPARγ (a transcription factor implicated in adiponectin gene expression through a PPAR-responsive element (PPRE) in its promoter). As a result, adiponectin expression is downregulated. Arrow indicates stimulation. Line indicates inhibition. MKK: MAP kinase kinase; pJNK: phosphorylated JNK.
