Effects of CAPE treatment on radiation-induced increases in inflammatory cytokine mRNA levels in vivo. The TGF-β, TNF-α, IL-1α/βand IL-6 mRNA levels (a) 6 hours (b) 24 hours after20 Gy irradiation. The results are expressed as RNA ratio. The RNA ratio was determined from the mRNA level at indicated time after treatment to control for a specific gene. Data are the mean ± SE. * P < 0.05, CAPE-treated irradiated mice versus CAPE-untreated irradiated mice.
