Figure EV1. FR prevents 5-HT-induced constriction and Gαq/Gα11 can be downregulated by lentiviral transduction.

Figure EV1

(A) Original traces of 5-HT dose–response curves (10−9 M–10−5 M) after pre-incubation with DMSO, Ket (10−6 M) or FR (10−6 M) in PAs. (B) PCR analysis of Gq protein subtypes in native mPASMCs and mPASMCs transduced with lentiviral sh-G11, sh-Gq RNA (negative controls). Murine lung tissue was used as positive control. (CF) Statistical analysis of relative Gα11 (C), Gαq (D), Gαi (E), and Gαs (F) mRNA expression in native mPASMCs (n = 3) and mPASMCs transduced with lentivirus (sh-control (ctrl), sh-G11, sh-Gq RNA or both, n = 3 independent experiments normalized to 18S housekeeping gene. (G, H) Original Western Blot (G) and analysis (H) of Gαq/11/14 protein expression of native mPASMCs and mPASMCs transduced with lentivirus (sh-control (ctrl), sh-G11, sh-Gq RNA or both, n = 3 independent experiments). GAPDH was used as housekeeper. Data information: Values are expressed as mean ± SEM. (CF, H) One-way ANOVA, Tukey’s post hoc test. Source data are available online for this figure.
