Effects of coffee extracts with different roasting degrees on mRNA expression levels of genes related to anti-inflammatory cytokines in LPS (15 mg/Kg.B.W/day)-injected C57BL/6 mice. Ten-week-old male C57BL/6 mice were pretreated with coffee extracts (300 mg/Kg.B.W/day) of four different roasting degrees for 10 days. The mRNA expression levels of (A) IL-10 and (B) IL-1α were measured by qRT-PCR and β-actin was used as a housekeeping gene. Different alphabets indicate significant differences (p < 0.05). Each bar represents the mean ± standard error (n = 6). LPS, lipopolysaccharide; IL-10, interleukin 10; IL-1α, interleukin 1-alpha; qRT-PCR, quantitative real-time reverse transcriptase-PCR.
