Stress-responsive genes and a persistent increase in Lcn2 expression induced by MALP-2. (A) HC11 cells were treated with LPS (10 µg/ml) or MALP-2 (10 ng/ml) for the indicated time periods and RNA samples prepared and quantified for IL-6, TNFα and cyclophilin mRNAs by RT-qPCR. The values for IL-6, TNFα were normalized to the cyclophilin values for the same sample and the zero time point for each gene set was used to normalize the results for all time points of that set. (B) HC11 cells were treated with 10 ng/ml MALP-2 for the time periods shown (MALP-2, Lcn2) or treated with MALP-2 for 4 hours then the cells were washed and the medium changed to the same medium lacking MALP-2 [MALP-2 (4 h), Lcn2]. Lcn2, TNFα and cyclophilin mRNA levels were quantified by RT-qPCR and normalized to cyclophilin. (C) HC11 cells were treated with MALP-2 at various concentrations for 12 h. Lcn2 and cyclophilin mRNAs were then quantified by RT-qPCR. All values were normalized to the average control value from cells treated with vehicle.
