TWEAK upregulates α-SMA expression in dermal fibroblasts. Human dermal fibroblasts in vitro received TWEAK stimulation. (A,B) The mRNA and protein expression levels of α-SMA were measured after 48-h stimulation. ^∗p < 0.05, compared with the 0 ng/ml group; Δp < 0.05, compared with the 10 ng/ml group. (C,D) The mRNA and protein expression levels of α-SMA were measured after 250 ng/ml stimulation (0–48 h). ^∗p < 0.05, compared with the 0 h group; Δp < 0.05, compared with the 12 h group. (E,F) By immunofluorescence and flow cytometry, the expression of α-SMA was detected in cells that received siRNA transfection plus TWEAK stimulation (250 ng/ml, 48 h). ^∗p < 0.05, compared with blank group; Δp < 0.05, compared with TWEAK alone group; #p < 0.05, compared with TWEAK + control siRNA group. n = 3. Representative images are shown. Bar = 5 μm.
