Negative correlation between the relative mRNA expression of RBP4 and IL-1β in human adipose tissue explants.

<p>RBP4 mRNA relative expression ratios in samples from subcutaneous adipose tissue of 18 healthy middle-aged females with a wide range of BMIs were determined by quantitative PCR and normalized to succinate dehydrogenase complex subunit A (SDHA) by 2^−ΔΔCT method. Due to a non-normal distribution, IL-1β mRNA relative expression ratios were subjected to logarithmic transformation. Correlation between RBP4 and IL-1β expression was determined by Pearson correlation coefficient (R = −0.535; p<0.05).
