IL-6 expression changes are confirmed by confocal microscopy and real time RT-PCR.

<p>(<b>A</b>) The increased IL-6 protein expression in the adipose tissues of obese and overweight individuals as compared with lean subjects was confirmed by confocal microscopy. (<b>B</b>) Real-time RT-PCR data also confirmed the increased IL-6 gene expression in obese adipose tissues (16.60±2.214 fold) as compared with lean/ overweight (9.376±1.656 fold) adipose tissue samples (<i>P</i> = 0.0108).
