Fig. 7. Inhibition of PRMT4 suppresses cell death in a LPS lung injury model.
A–D PRMT4 was silenced or overexpressed by i.t. administered lentiviral constructs for 14 days. Mice were then given (i.t.) LPS with or without a PRMT4 inhibitor as indicated for 24 h (n = 8). Lung tissues were stained with hematoxylin–eosin (H&E) (A, upper panels) and TUNEL staining (A, lower panels). B TUNEL-positive cells in lung tissues were quantitated. C PRMT4 overexpression and knockdown in lung tissues from A were analyzed by immunoblotting. The data from C were quantitated and plotted in D (n = 3). *P < 0.05 vs. scrambled control. Scale bar = 100 μm.
