GSS does not inhibit LPS‐induced GEF‐H1 activation but blocks LPS‐induced Myd88 expression. A, ECs were incubated with GSS for 2 h before LPS stimulation for 24 h, and the expression of Myd88 was determined by Western blot. B, The Western blot results are presented as a histogram showing the band intensity values. C, ECs were pre‐treated with GSS for 2 h followed by LPS stimulation for 24 h, and the inhibitory effect on GEF‐H1 was determined by Western blot. D, The Western blot results are presented as a histogram showing the band intensity values. *P < .05 vs negative control. ^# P < .05 vs the corresponding LPS treatment group
