Figure 9.

Effect of hydroxytyrosol (HT) on the expression levels of HSP60, a marker protein of the inflammation process in Raw264.7 cells previously subjected to inflammation caused by LPS (0.1 μg·mL⁻¹). Quantification of protein levels by densitometric analysis is shown in bar graphs. Results are means ± SEM (n = 9) and are expressed as percentage of expression compared to actin levels in Western-blot analysis. Different capital letters indicate the existence of significant differences (from p < 0.01 to p < 0.001) in the different experimental conditions. HSP60, Heat shock proteins (Chaperon) of 60 kDa; LPS, Lipopolysaccharide.
