Effect of tail domain and kinase domain mutations in BMPR2 on gene expression in rat Hc92 cells studied by RNA-Seq

Project description:We sequenced RNA from rat Hc92 cells transformed with empty vector, tail domain BMPR2 and kinase domain BMPR2 knockout vectors Comparison of Hc92 cells lacking BMPR2 tail domain vs those lacking BMPR2 kinase domain, using empty vector treated cells as control for both.

Transcription profiling of mouse inducible BMPR2 mutant vs. controls in lung with and without elevated RVSP

Project description:Familial pulmonary arterial hypertension (fPAH) is associated with mutations in BMPR2. Many of these mutations occur in the BMPR2 tail domain, leaving the SMAD functions intact. In order to determine the in vivo consequences of BMPR2 tail domain mutation, we created a smooth-muscle specific doxycycline inducible BMPR2 mutation with an arginine to termination mutation at amino acid 899. When these SM22-rtTA x TetO7-BMPR2R899X mice had transgene induced for 9 weeks, starting at 4 weeks of age, they universally developed pulmonary vascular pruning as assessed by fluorescent microangiography. Approximately half the time the induced animals developed elevated right ventricular systolic pressures (RVSP), associated with extensive pruning, muscularization of small pulmonary vessels, and development of large structural pulmonary vascular changes. These lesions included large numbers of macrophages and T-cells in their adventitial compartment, as well as CD133 positive cells in the lumen. Small vessels filled with CD45 positive and sometimes CD3 positive cells were a common feature in all SM22-rtTA x TetO7-BMPR2R899X mice. Gene array experiments show changes in stress response, muscle organization and function, proliferation and apoptosis, and developmental pathways before RVSP increases. Our results show that the primary phenotypic result of BMPR2 tail domain mutation in smooth muscle is pulmonary vascular pruning leading to elevated RVSP, associated with early dysregulation in multiple pathways with clear relevance to PAH. This model should be useful to the research community in examining early molecular and physical events in the development of PAH, and as a platform to validate potential treatments. Experiment Overall Design: Each array is an individual female mouse, age-matched, with two mice & arrays used for each of controls (transactivator only), BMPR2-R899X with normal RVSP, and BMPR2-R899X with high RVSP.

Proteomic changes in liver tissue of Rat (Rattus norvegicus) following formalin exposure

Project description:Formaldehyde (HCHO) is the simplest form of aldehyde and it is naturally present in a wide range of resources. In spite of its cosmopolitan presence, formaldehyde can have deleterious health effects at higher concentrations like leukemia. However, most of the studies carried out so far have focused on the effect of formaldehyde exposure through inhalation and not much has been studied on the its exposure through food. In this context, the present study was carried out to investigate the effect of formaldehyde exposure through drinking water on the liver proteome of rat which would not only be helpful in assessing the impact of formaldehyde on health of organisms but also would be helpful in understanding the mechanism of detoxification.

Structural basis for ALK2/BMPR2 receptor complex signaling through kinase domain oligomerization

Project description:Upon ligand binding, bone morphogenetic protein (BMP) receptors form active tetrameric complexes, comprised of two type I and two type II receptors, which then transmit signals to SMAD proteins. The link between receptor tetramerization and the mechanism of kinase activation, however, has not been elucidated. Here, using hydrogen deuterium exchange mass spectrometry (HDX-MS) and molecular dynamics (MD) simulations, combined with analysis of SMAD signaling, we show that the kinase domain of the type I receptor ALK2 and type II receptor BMPR2 form a heterodimeric complex via their C-terminal lobes. Formation of this dimer is essential for ligand-induced receptor signaling and is targeted by mutations in BMPR2 in patients with pulmonary arterial hypertension (PAH). We further show that the type I/type II kinase domain heterodimer serves as the scaffold for assembly of the active tetrameric receptor complexes to enable phosphorylation of the GS domain and activation of SMADs.
