Abstract
As an emerging discipline, panvascular diseases are a set of vascular diseases with atherosclerosis as the common pathogenic hallmark, which mostly affect vital organs like the heart, brain, kidney, and limbs. As the major responser to the most common stressor in the vasculature (hypoxia)-hypoxia-inducible factors (HIFs), and the primary regulator of pressure and oxygen delivery in the vasculature-vascular smooth muscle cells (VSMCs), their own multifaceted nature and their interactions with each other are fascinating. Abnormally active VSMCs (e.g., atherosclerosis, pulmonary hypertension) or abnormally dysfunctional VSMCs (e.g., aneurysms, vascular calcification) are associated with HIFs. These widespread systemic diseases also reflect the interdisciplinary nature of panvascular medicine. Moreover, given the comparable proliferative characteristics exhibited by VSMCs and cancer cells, and the delicate equilibrium between angiogenesis and cancer progression, there is a pressing need for more accurate modulation targets or combination approaches to bolster the effectiveness of HIF targeting therapies. Based on the aforementioned content, this review primarily focused on the significance of integrating the overall and local perspectives, as well as temporal and spatial balance, in the context of the HIF signaling pathway in VSMC-related panvascular diseases. Furthermore, the review discussed the implications of HIF-targeting drugs on panvascular disorders, while considering the trade-offs involved.

Hypoxia Triggers Osteochondrogenic Differentiation of Vascular Smooth Muscle Cells in an HIF-1 (Hypoxia-Inducible Factor 1)-Dependent and Reactive Oxygen Species-Dependent Manner.

Abstract
Objective- Vascular calcification is associated with high risk of cardiovascular events and mortality. Osteochondrogenic differentiation of vascular smooth muscle cells (VSMCs) is the major cellular mechanism underlying vascular calcification. Because tissue hypoxia is a common denominator in vascular calcification, we investigated whether hypoxia per se triggers osteochondrogenic differentiation of VSMCs. Approach and Results- We studied osteochondrogenic differentiation of human aorta VSMCs cultured under normoxic (21% O2) and hypoxic (5% O2) conditions. Hypoxia increased protein expression of HIF (hypoxia-inducible factor)-1α and its target genes GLUT1 (glucose transporter 1) and VEGFA (vascular endothelial growth factor A) and induced mRNA and protein expressions of osteochondrogenic markers, that is, RUNX2 (runt-related transcription factor 2), SOX9 (Sry-related HMG box-9), OCN (osteocalcin) and ALP (alkaline phosphatase), and induced a time-dependent calcification of the extracellular matrix of VSMCs. HIF-1 inhibition by chetomin abrogated the effect of hypoxia on osteochondrogenic markers and abolished extracellular matrix calcification. Hypoxia triggered the production of reactive oxygen species, which was inhibited by chetomin. Scavenging reactive oxygen species by N-acetyl cysteine attenuated hypoxia-mediated upregulation of HIF-1α, RUNX2, and OCN protein expressions and inhibited extracellular matrix calcification, which effect was mimicked by a specific hydrogen peroxide scavenger sodium pyruvate and a mitochondrial reactive oxygen species inhibitor rotenone. Ex vivo culture of mice aorta under hypoxic conditions triggered calcification which was inhibited by chetomin and N-acetyl cysteine. In vivo hypoxia exposure (10% O2) increased RUNX2 mRNA levels in mice lung and the aorta. Conclusions- Hypoxia contributes to vascular calcification through the induction of osteochondrogenic differentiation of VSMCs in an HIF-1-dependent and mitochondria-derived reactive oxygen species-dependent manner.

Decreased left ventricular stroke volume is associated with low-grade exercise tolerance in patients with chronic obstructive pulmonary disease. BMJ Open Respir Res 2017; 4:e000158. [PMID: 28176968 PMCID: PMC5278312 DOI: 10.1136/bmjresp-2016-000158] [Citation(s) in RCA: 5] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/12/2016] [Revised: 11/02/2016] [Accepted: 12/22/2016] [Indexed: 01/11/2023] Open
Abstract
BACKGROUND Low-grade exercise tolerance is associated with a poor prognosis in patients with chronic obstructive pulmonary disease (COPD). The 6 min walk test (6MWT) is commonly used to evaluate exercise tolerance in patients with COPD. However, little is known regarding the relationship between cardiac function and exercise tolerance in patients with COPD. The aim of this study was to identify predictive factors in cardiac function for low-grade exercise tolerance in patients with stable COPD. METHODS We recruited 57 patients with stable COPD (men 54, women 3) to perform the 6MWT. Patients with underlying orthopaedic disease or heart failure were excluded. Cardiac function was evaluated by echocardiography and contrast-enhanced cardiac CT. We also measured pulmonary function and the 6MWT distance. RESULTS Forced expiratory volume in 1 s (FEV1) and per cent predicted FEV, along with left ventricular end diastolic volume and left ventricular cardiac output as measured by cardiac CT, were significantly related to the 6MWT distance. On multivariate analysis, left ventricular stroke volume was the factor most closely associated with a decreased walked distance in the 6MWT. CONCLUSIONS Decreased left ventricular stroke volume was associated with low-grade exercise tolerance in patients with stable COPD without heart failure.
