Low oxygen (O2) levels are a naturally occurring feature of embryonic development, adult physiology, and diseases such as those of the cardiovascular system. Although many responses to O2 deprivation are mediated by hypoxia-inducible factors (HIFs), researchers are finding a growing number of HIF-independent pathways that promote O2 conformance and hypoxia tolerance. Here, we describe HIF-independent responses and how they impact cardiovascular tissue homeostasis.

The endothelium is the gatekeeper of vessel health, and its dysfunction is pivotal in driving atherogenesis. Here, we present a protocol to replicate endothelial-macrophage crosstalk during atherogenesis, called the "atherogenesis-on-chip" model, based on the Emulate dual-channel perfusion system. We describe a model for studying endothelial-macrophage interactions during atherogenesis in human aortic endothelial cells and human macrophages using qPCR and secretome analysis, fluorescence microscopy, and flow cytometry.

As an important element of the human body, iron participates in numerous physiological and biochemical reactions. In the past decade, ferroptosis (a form of iron-dependent regulated cell death) has been reported to contribute to the pathogenesis and progression of various diseases. The stability of iron in cardiomyocytes is crucial for the maintenance of normal physiological cardiac activity.

Background: Calcification of the radial artery is one of the main causes of anastomotic stenosis in autogenous arteriovenous fistulas in uremic patients. However, the pathogenesis of calcification is still unknown. This study attempted to screen and validate the risk factors for vascular calcification in patients with uremia.

Sodium-glucose cotransporter-2 inhibitors (SGLT2i) have shown efficacy in clinical trials for slowing chronic kidney disease (CKD) progression, but real-world data in diverse populations are limited. This retrospective study evaluated the effectiveness and safety of SGLT2i versus renin-angiotensin-aldosterone system (RAAS) blockade in CKD patients. Data from Ramathibodi Hospital (2010-2022) were analyzed, including 6,946 adults with CKD stages 2-4, with and without diabetes, who received SGLT2i (n = 1,405) or RAAS blockade (n = 5,541) for at least three months.

Osteogenic differentiation is crucial in normal bone formation and pathological calcification, such as calcific aortic valve disease (CAVD). Understanding the proteomic and transcriptomic landscapes underlying this differentiation can unveil potential therapeutic targets for CAVD. In this study, we employed RNA sequencing transcriptomics and proteomics on a timsTOF Pro platform to explore the multiomics profiles of valve interstitial cells (VICs) and osteoblasts during osteogenic differentiation.
