Figure Lengend Snippet: IRAK1 is required for CC chemokine secretion. (A and B), HaCaT cells were transfected with expression constructs encoding a scrambled negative control shRNA sequence (open bars) or IRAK1 specific shRNA (filled bars). (C and D), cells were transfected with either an empty (open bars) or IRAK1(1-217) (filled bars) expression construct. Geneticin selected cells were treated with medium only, 10 ng/ml IL-1β or 50 ng/ml TNF-α for 24 hours. Secretion of CCL5 (A and C) and CCL20 (B and D) was determined by ELISA. Expression of CCL5 and CCL20 in the control cells (open bars, scrambled shRNA (A and B) or empty vector (C and D)) was defined as 100 pct. Expression of CCL5 and CCL20 in the IRAK1 targeted cells (filled bars, IRAK1 specific shRNA (A and B) or IRAK1(1-217) expression vector (C and D)) is graphically represented relative to the control cells. * p < 0.05 compared to control cells transfected with scrambled shRNA plasmid (A and B) or empty vector (C and D) and receiving the same treatment.
Article Snippet: Control plasmid containing a scrambled shRNA sequence was also obtained from SuperArray.
