Figure Lengend Snippet: Drug prediction based on the common upregulated downstream targets after ALK1, ENG and SMAD4 knockdown and experimental validation in PMVECs. A) Experimental strategy: the common upregulated genes 117 (2h) and 112 (24h) after knockdown of the three HHT genes and stimulation with BMP9 for 2 and 24hrs (HHT disease signature) were uploaded separately on the Clue query app. The criteria of the drugs rank include samples >=3, normalized connectivity score, tas value >=0.20, and FDR value. B) top scoring 5 HHT (positive values) and anti-HHT drugs (negative values, indicated by brown color) are represented. (C-K) Effect of Brivanib on the expression of the common persistent downstream targets (LYVE1, GPNMB, RRAGD, ANKRD33, HS3ST2, MC5R, SLC25A47, FGF19, SHISA9, FRG2C, HIST1H2BE, and CPA4) after ALK1, ENG and SMAD4 knockdown was assessed by qRT-PCR in PMVECs. MOA, mode of action; cs, connectivity score; tas, transcriptional activity score. Data are represented as mean ± standard error mean (n=3). Two-way repeated measures ANOVA with a Bonferroni post-hoc test, * P= <0.5, ** P= <0.01, *** P= <0.001, **** P= <0.0001.
Article Snippet: Human healthy control pulmonary microvascular endothelial cells (PMVECs) (Cat # C12281, PromoCell GmbH, Heidelberg, Germany) were cultured in microvascular endothelial cell basal media (Cat # C-22120; PromoCell GmbH) supplemented with growth factors (Growth Medium MV SupplementPack, Cat # C-39220, PromoCell GmbH) and 100 U/mL Penicillin-Streptomycin Solution (Gibco) and used between passages 4 to 8.
