Project description:Studies in various animal models suggest an important role for pulmonary macrophages in the pathogenesis of pulmonary hypertension (PH). Yet, the molecular mechanisms characterizing the functional macrophage phenotype relative to time and pulmonary localization/compartmentalization remain largely unknown. Here, we utilized a hypoxic murine model of PH in combination with flow cytometry assisted cell sorting (FACS) to quantify and isolate lung macrophages from two compartments over time and characterized their programing via RNA sequencing (RNAseq) approaches. In response to hypoxia, we found an early increase in macrophage number that was restricted to the interstitial/perivascular compartment, without recruitment of macrophages to the alveolar compartment or changes in the number of resident alveolar macrophages. Principle component analysis demonstrated significant differences in overall gene expression between alveolar (AMs) and interstitial macrophages (IMs) at baseline and after 4 and 14 days hypoxic exposure. AM’s at both day 4 and 14 and IM’s at day 4 shared a conserved “hypoxia program” characterized by mitochondrial dysfunction, pro-inflammatory gene activation and mTORC1 signaling, while IM’s at day 14 demonstrated a unique anti-inflammatory/ pro-reparative programming state. We conclude that the pathogenesis of vascular remodeling in hypoxic PH involves an early compartment independent activation of lung macrophages towards a conserved hypoxia program, with the development of compartment specific programs later on in the course of disease. Thus, harnessing time and compartment specific differences in lung macrophage polarization needs to be considered in the therapeutic targeting of macrophages in hypoxic PH and potentially other inflammatory lung diseases.

Project description:The potential roles of mRNAs and lncRNAs in the development and the reoxygenation treatment of reversal of hypoxic pulmonary hypertension are still unknown. 24 healthy adult male C57/BL6 mice were divided into three groups (normoxia group, hypoxia group, hypoxia-normoxia group), lncRNA and mRNA microarray was performed，meanwhile，the changes of right ven-tricular systolic pressure (RVSP) and other physiological indexes were measured in the three groups. The results showed that the index of RVSP, the right ventricular hypertrophy index RV/(LV+S), pulmonary artery walls and the muscularization ratio of pulmonary arterioles were significantly increased after Hypoxia treatment, while they were attenuated after the normoxia condition restored. Moreover, the study revealed there were 62 lncRNAs and 99 mRNAs with significant difference expression were associated with the reversal of hypoxic pulmonary hypertension by reoxygenation in mice. Furthermore, the pathway enrichment and gene ontology analysis of 99 DEGS were performed. Interestingly, the result suggested that chemokine subfamily CCL2/ CXCL played a role in the occurrence, development and reversion of pulmonary hypertension by reoxygenation. This study was the first time to demonstrate the transcriptome profiles of lncRNAs and mRNAs in the lung tissue during the reversal of hypoxic pulmonary hypertension in mice by reoxygenation, which might further broaden the understanding of the pathogenesis and the therapeutic effect of oxygen recovery of hypoxic pulmonary hypertension.

Project description:Introgressed variants from other species can be an important source of genetic variation because they may arise rapidly, can include multiple mutations on a single haplotype, and have often been pretested by selection in the species of origin. Although introgressed alleles are generally deleterious, several studies have reported introgression as the source of adaptive alleles-including the rodenticide-resistant variant of Vkorc1 that introgressed from Mus spretus into European populations of Mus musculus domesticus. Here, we conducted bidirectional genome scans to characterize introgressed regions into one wild population of M. spretus from Spain and three wild populations of M. m. domesticus from France, Germany, and Iran. Despite the fact that these species show considerable intrinsic postzygotic reproductive isolation, introgression was observed in all individuals, including in the M. musculus reference genome (GRCm38). Mus spretus individuals had a greater proportion of introgression compared with M. m. domesticus, and within M. m. domesticus, the proportion of introgression decreased with geographic distance from the area of sympatry. Introgression was observed on all autosomes for both species, but not on the X-chromosome in M. m. domesticus, consistent with known X-linked hybrid sterility and inviability genes that have been mapped to the M. spretus X-chromosome. Tract lengths were generally short with a few outliers of up to 2.7 Mb. Interestingly, the longest introgressed tracts were in olfactory receptor regions, and introgressed tracts were significantly enriched for olfactory receptor genes in both species, suggesting that introgression may be a source of functional novelty even between species with high barriers to gene flow.

Project description:Pulmonary arterial hypertension (PAH) is a progressive disease in which pulmonary arterial (PA) endothelial cell (EC) dysfunction is associated with unrepaired DNA damage. BMPR2 is the most common mutant gene in PAH. We report that human PAEC with reduced BMPR2 have persistent DNA damage in room air after hypoxic exposure (reoxygenation), as do mice with EC deletion of Bmpr2 (EC-Bmpr2-/-) and persistent pulmonary hypertension. Similar findings are observed in PAEC with loss of the DNA damage sensor ATM, and in mice with Atm deleted in EC (EC-Atm-/-). Gene expression analysis of EC-Atm-/- and EC-Bmpr2-/- lung EC revealed reduced Foxf1, a transcription factor with relative selectivity for lung EC. Reducing FOXF1 in control PAEC induced DNA damage and impaired angiogenesis whereas transfection of FOXF1 in PAH PAEC repaired DNA damage and restored angiogenesis. Lung EC targeted delivery of Foxf1 to reoxygenated EC-Bmpr2-/- mice repaired DNA damage, induced angiogenesis and reversed pulmonary hypertension.
