C) Relative hGM-CSF and hIL-12 Torin 2 solubility dmso expression in A549 cells. D) Relative hGM-CSF and hIL-12 expression in Hep3B cells. HT: heating treatment. N = 5 repeated experiments. The effect of heat treatments on hGM-CSF and hIL-12 expression As shown in Figure 3A in non-heated A549 cells, first heat

treatment significantly increased hIL-12 levels in A549 cells infected with 100 vp 500 vp, 1000 vp virus, respectively, while the second heat treatment was more efficient in increasing hIL-12 levels in A549 cells (p < 0.05 at all 3 viral dosages). In non-heat treated Hep3B cells, first heat treatment significantly increased hIL-12 expressions in Hep3B cells 24 hrs after first heat treatment. The second heat treatment was also more efficient in increasing hIL-12 levels in Hep3B (p < 0.05 at all 3 viral dosages). These results suggest JAK inhibitor that hIL-12 expression is heat-inducible. In contrast, first heat treatment significantly increased hGM-CSF expression in A549 cells infected with 500 vp and 1000 vp virus in non-heat treated A549 cells shown in Figure 3B; however, second heat treatment did

not significantly increase hGM-CSF expression in A549 cells (p > 0.05). Selleckchem MEK inhibitor In non-heat treated Hep3B cells, first heat treatment increased hGM-CSF levels in Hep3B cells but showed no statistical difference (p > 0.05). After second heat treatment, significant difference was observed in Hep3B cells infected with 1000 vp virus. These results suggest that heat treatment can increase hGM-CSF

expression, but hGM-CSF expression is not heat-dependent. Figure 3 The time dependence Fenbendazole of hGM-CSF and hIL-12 expression in heat treated A549 and Hep3B cells. Cells were infected and heated as described in Figure 2. Medium was collected at 24 and 48 hrs after heating treatment. A) hIL-12 expression in A549 and Hep3B cells. B) hGM-CSF expression in A549 and Hep3b cells. C) Comparison of hIL-12 expression between cells heated for 24 hrs and cells without heating for 24 and 48 hrs. D) Comparison of hGM-CSF expression between cells heated for 24 hrs and cells without heating for 24 and 48 hrs. N = 5 repeated experiments. We further compared the expression of hIL-12 (Figure 3C) and hGM-CSF (Figure 3D) in A549 and Hep3B cells infected with the virus underlying heat treatment for 24 hrs and no heat treatment for 24 and 48 hrs. Results showed that there were no significant differences in hIL-12 levels between 24 and 48 hrs in both A549 and Hep3B cells infected with 3 different viral doses underlying no heat treatment, but a significant increase in A549 and Hep3B cells was observed after 24 hrs of heat treatment. These results suggest that hIL-12 expression is heat-inducible, but not time-dependent. In contrast, significant differences in hGM-CSF levels were observed in A549 and Hep3B cells infected with 500 vp and 1000 vp virus underlying no heat treatment for 24 and 48 hrs.
