Abstract
Aging is a major risk factor for impaired cardiovascular health. Because the aging myocardium is characterized by microcirculatory dysfunction, and because nerves align with vessels, we assessed the impact of aging on the cardiac neurovascular interface. We report that aging reduces nerve density in the ventricle and dysregulates vascular-derived neuroregulatory genes. Aging down-regulates microRNA 145 (miR-145) and derepresses the neurorepulsive factor semaphorin-3A. miR-145 deletion, which increased Sema3a expression or endothelial Sema3a overexpression, reduced axon density, mimicking the aged-heart phenotype. Removal of senescent cells, which accumulated with chronological age in parallel to the decline in nerve density, rescued age-induced denervation, reversed Sema3a expression, preserved heart rate patterns, and reduced electrical instability. These data suggest that senescence-mediated regulation of nerve density contributes to age-associated cardiac dysfunction.

Abstract
RATIONALE Nox4 is a constitutively active NADPH oxidase that constantly produces low levels of H2O2. Thereby, Nox4 contributes to cell homeostasis and long-term processes, such as differentiation. The high expression of Nox4 seen in endothelial cells contrasts with the low abundance of Nox4 in stem cells, which are accordingly characterized by low levels of H2O2. We hypothesize that Nox4 is a major contributor to endothelial differentiation, is induced during the process of differentiation, and facilitates homeostasis of the resulting endothelial cells. OBJECTIVE To determine the role of No×4 in differentiation of murine inducible pluripotent stem cells (miPSC) into endothelial cells (ECs). METHODS AND RESULTS miPSC, generated from mouse embryonic wildtype (WT) and Nox4-/- fibroblasts, were differentiated into endothelial cells (miPSC-EC) by stimulation with BMP4 and VEGF. During this process, Nox4 expression increased and knockout of Nox4 prolonged the abundance of pluripotency markers, while expression of endothelial markers was delayed in differentiating Nox4-depleted iPSCs. Eventually, angiogenic capacity of iPSC-ECs is reduced in Nox4 deficient cells, indicating that an absence of Nox4 diminishes stability of the reached phenotype. As an underlying mechanism, we identified JmjD3 as a redox target of Nox4. iPSC-ECs lacking Nox4 display a lower nuclear abundance of the histone demethylase JmjD3, resulting in an increased triple methylation of histone 3 (H3K27me3), which serves as a repressive mark for several genes involved in differentiation. CONCLUSIONS Nox4 promotes differentiation of miPSCs into ECs by oxidation of JmjD3 and subsequent demethylation of H3K27me3, which forced endothelial differentiation and stability.

Abstract
Background:
The modulation of vascular smooth muscle cells (VSMC) phenotypes is a highly important process in the formation of neointima and in resolution of inflammation after vascular injury. Underlying genetic mechanisms that control the phenotypic switch of VSMC in disease are not completely understood. On this basis, the phenotypic regulation of VSMC in restenosis development was examined in the mouse carotid artery injury model.
Methods and Results:
Wire-induced injury, an established mouse-model to study restenosis, was applied to induce vascular injury in C57BL/6 mice. Time-resolved single-cell RNA-sequencing (scRNAseq) and massive-analysis-of-cDNA-ends (MACE)-RNAseq of neointima obtained by laser capture microdissection were performed to detect genetic changes in neointima development. Single-cell RNA-sequencing of C57BL/6 mice at different time points after wire-induced injury revealed an expanding, highly proliferative activated VSMC cluster, which exhibited low expression of SMC marker genes. Analysis for differentially regulated genes (DEG) and pseudotime clustering identified a unique marker gene signature, including high expression of TIMP Metallopeptidase Inhibitor 1 (Timp1), which was identified as main ordering gene of the modulation processes′ pseudo temporal states. MACEseq confirmed upregulation of Timp1 selectively in neointima forming VSMCs. Integration with atherosclerosis scRNAseq data indicated differences in gene signatures of activated VSMC populations. Transcription factor analysis of modulated VSMC identified BACH1, a factor involved in reactive oxidative stress response and proliferation of SMCs, as potential regulatory target for re-differentiation of VSMCs after vascular injury.
Conclusion:
ScRNAseq identified a unique cell cluster responsible for neointima formation. Targeting the transcription factors driving the cluster (like BACH1) can be exploited to combat neointima development.

Abstract
BACKGROUND Circular RNAs (circRNAs) are generated by back splicing of mostly mRNAs and are gaining increasing attention as a novel class of regulatory RNAs that control various cellular functions. However, their physiological roles and functional conservation in vivo are rarely addressed, given the inherent challenges of their genetic inactivation. Here, we aimed to identify locus conserved circRNAs in mice and humans, which can be genetically deleted due to retained intronic elements not contained in the mRNA host gene to eventually address functional conservation. METHODS AND RESULTS Combining published endothelial RNA-sequencing data sets with circRNAs of the circATLAS databank, we identified locus-conserved circRNA retaining intronic elements between mice and humans. CRISPR/Cas9 mediated genetic depletion of the top expressed circRNA cZfp292 resulted in an altered endothelial morphology and aberrant flow alignment in the aorta in vivo. Consistently, depletion of cZNF292 in endothelial cells in vitro abolished laminar flow-induced alterations in cell orientation, paxillin localization and focal adhesion organization. Mechanistically, we identified the protein SDOS (syndesmos) to specifically interact with cZNF292 in endothelial cells by RNA-affinity purification and subsequent mass spectrometry analysis. Silencing of SDOS or its protein binding partner Syndecan-4, or mutation of the SDOS-cZNF292 binding site, prevented laminar flow-induced cytoskeletal reorganization thereby recapitulating cZfp292 knockout phenotypes. CONCLUSIONS Together, our data reveal a hitherto unknown role of cZNF292/cZfp292 in endothelial flow responses, which influences endothelial shape.

Abstract
Objective The NADPH oxidase Nox4 is an important source of H2O2. Nox4-derived H2O2 limits vascular inflammation and promotes smooth muscle differentiation. On this basis, the role of Nox4 for restenosis development was determined in the mouse carotid artery injury model. Methods and results Genetic deletion of Nox4 by a tamoxifen-activated Cre-Lox-system did not impact on neointima formation in the carotid artery wire injury model. To understand this unexpected finding, time-resolved single-cell RNA-sequencing (scRNAseq) from injured carotid arteries of control mice and massive-analysis-of-cDNA-ends (MACE)-RNAseq from the neointima harvested by laser capture microdissection of control and Nox4 knockout mice was performed. This revealed that resting smooth muscle cells (SMCs) and fibroblasts exhibit high Nox4 expression, but that the proliferating de-differentiated SMCs, which give rise to the neointima, have low Nox4 expression. In line with this, the first weeks after injury, gene expression was unchanged between the carotid artery neointimas of control and Nox4 knockout mice. Conclusion Upon vascular injury, Nox4 expression is transiently lost in the cells which comprise the neointima. NADPH oxidase 4 therefore does not interfere with restenosis development after wire-induced vascular injury.

Abstract
OBJECTIVE Oxidative stress is a risk factor for atherosclerosis. NADPH oxidases of the Nox family produce ROS but their contribution to atherosclerosis development is less clear. Nox2 promotes and Nox4 rather limits atherosclerosis. Although Nox1 with its cytosolic co-factors are largely expressed in epithelial cells, a role for Nox1 for atherosclerosis development was suggested. To further define the role of this homologue, the role of its essential cytosolic cofactor, NoxO1, was determined for atherosclerosis development with the aid of knockout mice. METHODS AND RESULTS Wildtype (WT) and NoxO1 knockout mice were treated with high fat diet and adeno-associated virus (AAV) overexpressing pro-protein convertase subtilisin/kexin type 9 (PCSK9) to induce hepatic low-density lipoprotein (LDL) receptor loss. As a result, massive hypercholesterolemia was induced and spontaneous atherosclerosis developed within three month. Deletion of NoxO1 reduced atherosclerosis formation in brachiocephalic artery and aortic arch in female but not male NoxO1-/- mice as compared to WT littermates. This was associated with a reduced pro-inflammatory cytokine signature in the plasma of female but not male NoxO1-/- mice. MACE-RNAseq of the vessel did not reveal this signature and the expression of the Nox1/NoxO1 system was low to not detectable. CONCLUSIONS The scaffolding protein NoxO1 plays some role in atherosclerosis development in female mice probably by attenuating the global inflammatory burden.

Abstract
AIMS The protein Scrib (Scribble 1) is known to control apico-basal polarity in epithelial cells. The role of polarity proteins in the vascular system remains poorly characterized; however, we previously reported that Scrib maintains the endothelial phenotype and directed migration. On this basis, we hypothesized that Scrib has anti-atherosclerotic functions. METHODS AND RESULTS Tamoxifen-induced Scrib-knockout mice were crossed with ApoE-/- knockout mice and spontaneous atherosclerosis under high-fat diet (HFD), as well as accelerated atherosclerosis in response to partial carotid artery ligation and HFD, was induced. Deletion of Scrib resulted in increased atherosclerosis development in both models. Mechanistically, flow- as well as acetylcholine-induced endothelium-dependent relaxation and AKT phosphorylation was reduced by deletion of Scrib, whereas vascular permeability and leucocyte extravasation were increased after Scrib knockout. Scrib immune pull down in primary carotid endothelial cells and mass spectrometry identified Arhgef7 (Rho Guanine Nucleotide Exchange Factor 7, βPix) as interaction partner. Scrib or Arhgef7 down-regulation by siRNA reduced the endothelial barrier function in human umbilical vein endothelial cells. Gene expression analysis from murine samples and from human biobank material of carotid endarterectomies indicated that loss of Scrib resulted in endothelial dedifferentiation with a decreased expression of endothelial signature genes. CONCLUSIONS By maintaining a quiescent endothelial phenotype, the polarity protein Scrib elicits anti-atherosclerotic functions.
