Summary: Intravenous delivered nanomedicine needs to escape from the blood vessel to exert therapeutic effects. While many powerful anticancer nanomedicine strategies rely on the tumor-derived enhanced permeability and retention (EPR) effect for escaping, it is not applicable to all tumors. Recent advancements have been made in inducing endothelial leakiness at the tumor to decrease reliance on EPR.

Summary: DNM2 plays a crucial role in cancer by promoting cell migration, invasion, metastasis, as well as tumor cell proliferation and survival. Therapeutic targeting of DNM2 has shown promising results in reducing cell proliferation, inducing apoptosis, and reducing invasive phenotype in cancer cells, both in vitro and in vivo animal models.

Summary: The production of plastics has played a crucial role in modern society, but the accumulation of plastics in the environment poses a significant threat to environmental sustainability and human health. This study focuses on the biological effects of nanoplastics, specifically anionic polystyrene and poly(methyl methacrylate), and reports that their introduction disrupts the vascular endothelial cadherin junctions. The findings provide important insights into the behavior and impact of nanoplastics, which can guide innovations for a sustainable plastics industry and environmental remediation.

Summary: Nanoparticles with unique physicochemical properties can overcome biological barriers and are considered one of the best materials with anticancer properties. The interaction of nanoparticles with the endothelium can lead to nanoparticle-modulated endothelial leakiness (NanoEL), which can be beneficial for drug delivery but also carries risks. Understanding the mechanism and degree of induction of NanoEL, as well as the potential risks, is crucial for the development of effective therapeutic strategies.

Summary: This study found that DKK1 was upregulated in patients with PH, hypoxia-induced PH mice, and human pulmonary artery endothelial cells. DKK1 regulated SHMT2 transcription, impacting cellular metabolism and mitochondrial function, leading to a proproliferative and antiapoptotic phenotype in endothelial cells. Treatment with a neutralizing anti-DKK1 antibody showed potential in attenuating PH.

Summary: This study investigated the expression profiles of dynamin isoforms and their roles in endocytosis in brain endothelial cells. Dyn2 was found to be the highest expressed isoform, and it was necessary for transferrin uptake and played a role in the late stage of vesicle fission during endocytosis. The results suggested that Dyn2 mediates clathrin-dependent endocytosis for amyloid-beta internalization from basolateral to apical side into brain endothelial cells, while Dyn1 and Dyn3 did not have the same role.

Summary: Cerebrovascular microcirculation is crucial for brain function, and angiogenesis plays a significant role in remodeling the microcirculation. Hypoxia is an important regulator of angiogenesis, but it also negatively affects cerebral vascular tissue. Establishing a model that promotes cerebral microvasculogenesis without causing injury is essential.

Summary: Research has identified dynamin 2 and pacsine 2 as functional partners in podosomes of Src-transformed NIH 3T3 cells, co-operatively regulating the organization of podosomes. They interact and promote each other's localization at podosomes, thereby affecting podosome formation and maturation.

Summary: This study investigates the molecular mechanisms underlying the regulation of actin by dynamin in human podocytes. The results suggest that the affinity of the K562E mutant for lipid membranes and its atypical self-assembling properties lead to actin disorganization in podocytes. Furthermore, the interaction between actin and membranes mediated by dynamin is critical for actin bundle formation and podocyte morphology and functions.

Summary: Oxidative stress is a driving factor in the pathogenesis of atrial fibrillation (AF), with hydrogen sulfide (H2S) playing an important role in regulating electrical remodeling and susceptibility to AF. Patients with AF had significantly lower plasma sulfide levels, and those with persistent AF had even lower levels compared to paroxysmal AF patients. Additionally, CSE knockout mice showed decreased atrial sulfide levels, increased atrial superoxide levels, and enhanced propensity for induced persistent AF compared to wild type mice.

Summary: Cigarette smoking increases the risk of acute respiratory distress syndrome (ARDS) and causes emphysema. Smoke-exposed AKR mice were found to be more susceptible to LPS-induced acute lung injury (ALI) than C57BL/6 mice. Therefore, we investigated strain-dependent lung transcriptomic responses to cigarette smoke (CS).

Summary: Using single-cell mass cytometry, researchers have identified a subpopulation of human cardiac fibroblasts in fibrotic tissue of pulmonary arterial hypertension patients that display features of both mesenchymal and lymphoid origin cells. Induction of IL-1 beta in these fibroblasts results in immune competency and suggests modulation of fibroblast secretome as a potential therapeutic approach for pulmonary arterial hypertension and other inflammation-related fibrotic diseases.
