Effect of the induction of heat shock proteins (HSP) on the expression of inflammatory cytokines in the aorta in ApoE−/− mice. (A) Interleukin 6 (IL-6) and tumor necrosis factor-alpha (TNF-alpha) mRNA expression levels in the aorta after geranylgeranylacetone (GGA) administration. 10-week-old ApoE−/− mice, evidencing the formation of atheromas, were administered vehicle or GGA (500 mg/kg/day) for 24 h. Then, total RNA was extracted from the aorta. (B) IL-6 and TNF-alpha mRNA expression levels in the aorta after heat shock treatment. 10-week-old ApoE−/− mice, demonstrating the formation of atheromas, were treated in a 30 °C (control) or 41 °C (heat shock) warm bath for 30 min. After 24 h, total RNA was extracted from the aorta. Each bar represents the mean ± standard deviation (SD). Significant differences are marked on the chart (*p < 0.05; **p < 0.01). n = 5–8 mice per group.
