Fig. 6 Functional studies related to loss of BMPR2 in human monocytes. Induced pluripotent stem cells (iPSC) derived from HPAH patients or Controls were differentiated into induced monocytes (iMono) using a stepwise differentiation protocol outlined in the Methods. iMono of HPAH patients and Controls were compared for (A) CD14 cell surface expression, assessed by FACS; (B) Number of iMono per mL. on day 19 of differentiation.

( a-b ) Transfecting siPGR (200nM, 72 hr) effectively downregulated the mRNA and protein of PGR. ( c-e ) Knockdown of PGR reversed the pro-proliferative effects of progesterone (for 24 hr) in BMPR2-knockdown PASMCs. (c) used Alarmar blue assay, and (d-e) were EdU assay and its statistical graph. ( f ) Knockdown of PGR reversed the upregulation of these proteins induced by progesterone (for 2 hr) in BMPR2-knockdown PASMCs. Abbreviation: PGR, progesterone receptor. *, P <0.05; **, P <0.01; ***, P <0.001.

( a-b ) Progesterone (for 2 hr) promoted the nuclear translocation of c-JUN in BMPR2– knockdown PASMCs, which could be reversed by knockdown of PGR. ( c ) Nucleus and cytoplasm ratio of mean fluorescence intensity of c-JUN. ( d ) Compared with RLP30 (the positive control) and IgG (the negative control), the %input of cJUN was over 4%, demonstrating its binding to the promoter region of EDN1. ( e ) JASPAR database predicted that AP-1 (the dimer of c-JUN and c-FOS) could combine onto the promoter region of EDN1.

( a ) Alarmar blue assay showed that progesterone (24 hr) upregulated the proliferation in iPSCs-VSMCs of a HPAH patient, but not influenced iPSCs-VSMCs of a normal person. ( b-c ) Transwell assay showed that progesterone upregulated the migration (8 hr) in iPSCs-VSMCs of a HPAH patient, but not influenced iPSCs-VSMCs of a normal person. ( d ) Progesterone (2 hr) induced the phosphorylation of ERK in iPSCs-VSMCs. ( e ) In comparison with normal iPSCs-VSMCs, EDN1 was significantly increased in PAH iPSCs-VSMCs that could be further upregulated by progesterone (24 hr). Abbreviation: iPSCs, induced pluripotent stem cells; VSMCs, vascular smooth muscle cells; HPAH, hereditary pulmonary artery hypertension; BMPR2 mut, BMRP2-mutation carrier; WT, wild type. ns, non-significance; *, P <0.05.
