Indoxyl sulfate and p-cresyl sulfate directly promote vascular calcification via activation of inflammation and coagulation pathways

ABSTRACT: Vascular calcification contributes to high cardiovascular mortality in chronic kidney disease (CKD) patients. An association between the uremic toxins indoxyl sulfate (IS) and p-cresyl sulfate (PCS) and cardiovascular disease has been suggested. This study provides strong etiological evidence for indoxyl sulfate and p-cresyl sulfate as major contributors to vascular calcification in chronic kidney disease patients. Continuous exposure to indoxyl sulfate or p-cresyl sulfate in rats with chronic kidney disease promotes moderate to severe calcification in the aorta and peripheral vessels. Unbiased proteomic analyses of arterial samples coupled to functional bioinformatics annotation analysis revealed that calcification events were associated with acute phase response signaling, coagulation and glucometabolic signaling pathways, while escape from toxin-induced calcification was linked with liver X receptors and farnesoid X/liver X receptor signaling pathways. Activation of inflammation and coagulation pathways in the arterial wall plays a pivotal role in toxin-induced calcification and strongly associates with hyperglycemia and insulin resistance. These findings reveal new perspectives to establish novel therapeutic targets to prevent, halt progression or cure vascular calcification.

<h4>Background</h4>Protein-bound uremic toxins indoxyl sulfate (IS) and p-cresyl sulfate (PCS) have been associated with cardiovascular morbidity and mortality in patients with CKD. However, direct evidence for a role of these toxins in CKD-related vascular calcification has not been reported.<h4>Methods</h4>To study early and late vascular alterations by toxin exposure, we exposed CKD rats to vehicle, IS (150 mg/kg per day), or PCS (150 mg/kg per day) for either 4 days (short-term exposure) or ...[more]

Project description:The microcirculation serves crucial functions in adult heart that are distinct from those carried out by epicardial vessels. Microvessels are also governed by unique regulatory mechanisms, impairment of which leads to microvessel-specific pathology. While great progress has been made in understanding and treating coronary artery disease (CAD), there are few treatment options for patients with microvascular heart disease, primarily due to our limited understanding of underlying pathology. The advent of high-throughput analytical approaches of mRNA and protein expression in specific cells provides an opportunity to transform our understanding of microvessel biology and disease at the molecular level. Understanding responses of individual microvascular cells to the same physiological or pathophysiological stimuli requires the ability to isolate the specific cell types that comprise the functional units of the microcirculation in an adult heart, preferably from the same heart, to ensure that different cells have been exposed to the same in-vivo conditions. Furthermore, in-vitro functional and molecular analysis requires an integrated workflow that combines primary cell culture with high-throughput proteomic or transcriptomic analysis. Our goal was an integrated process for simultaneous isolation, culture, and proteomic profiling of the three main cell types comprising the microcirculation in adult mouse heart: endothelial cells (ECs), pericytes (PCs) and vascular smooth muscle cells (VSMCs). We developed an integrated platform for simultaneous isolation and culture of ECs, PCs and VSMCs from adult mouse heart, coupled with unbiased mass spectrometry (MS)-based characterization of protein expression in these cells. We defined microvascular cell proteomes, identified novel protein markers and confirmed established cell-specific markers. Isolating and analyzing microvascular cell types separately from the same preparation of adult mouse hearts allowed for separate investigations into the unique contributions of the different cell types to health and disease, and interactions among different cell types.
