ETA receptor overexpression alters cell cycle in 661W cells. a Representative images. FACS analysis of cell cycle in empty and ETA receptor vector 661W stable clones following 24 h treatment with either 100 nM ET-1 or ET-3. Arrows show Sub G peak; arrowheads show G0/G1 peak. b–d Quantitation of b cell cycle phases, c G0/G1 phase and d Sub G phase. Bars represent mean ± SEM (n = 3). Asterisks indicated statistical significance *p < 0.05, by one-way ANOVA and Tukey’s post hoc test. ns no statistical significance
