Figure Lengend Snippet: a , Phosphokinase array and densitometric quantification of serum-starved hVSMCs treated for 15 min with 500 ng ml −1 rhTIMP1 or vehicle control ( N = 1 donor). b , Western blot of total STAT3, phospho-STAT3 (S727 or Tyr705), total AKT, phospho-AKT (pAKT), total p38a, phospho-p38a (p-p38a) and GAPDH in serum-starved hVSMCs after 0 min, 5 min, 10 min, 15 min and 30 min rhTIMP1. c , Quantification of relative western blot band intensity, normalized to GAPDH. The points show independent hVSMC isolates ( N = 4), the bars indicate the means, and the error bars indicate s.e.m.; P value: one-way ANOVA. d , Number of clonally expanded patches formed by lineage-labeled VSMCs following 21 days of culture, without (white, circles) or with 500 ng rmTIMP1 (blue, squares) in samples treated with vehicle (DMSO), 10 µM TT101 (STAT3i), 100 nM MK-2206 (AKTi), 10 µM SB202474 (control inhibitor, ctrl), 10 µM SB203580 (p38i1) or 10 µM SB202190 (p38i2). The points show averages ( N = 3 Myh11–Confetti animals analyzed in triplicate), the bars indicate means, the error bars indicated s.e.m.; P value: two-tailed t -test. e , Quantification over time of clonally expanded patches formed by lineage-labeled VSMCs, treated with non-targeting control (NTC) or Stat3 -targeting siRNA (siSTAT3) ±500 ng rmTIMP1. The points indicate means ( N = 3 Myh11–Confetti animals analyzed in triplicate), and the error bars indicated s.e.m.; P = 2.2 × 10 −7 , generalized linear model. f , ChIP–qPCR analysis at STAT3 targets ( TWIST and JUNB ) and negative control ( AMICA1 ), in serum-starved control and rhTIMP1-treated hVSMCs (15 min, 500 ng ml −1 ), showing anti-STAT3 and control-IgG precipitated DNA as a percentage of the input. The bars show the means of independent hVSMC isolates ( N = 3 donors), and the error bars indicate the s.e.m.; P value: two-tailed t -test. g , pSTAT3 S727 immunostaining (magenta) in cryosections from carotid plaque in an Myh11–Confetti/Apoe animal (11 weeks HFD) with Myh11–Confetti signals (CFP, blue; RFP, red; YFP, yellow; GFP, green).
