Attenuating Atherosclerosis through Inhibition of the NF-B/NLRP3/IL-1 Pathway-Mediated Pyroptosis in Vascular Smooth Muscle Cells (VSMCs).

Objective: We investigated the effects of resveratrol (Res) and MCC950 on the pyroptosis of vascular smooth muscle cells (VSMCs) and the potential pathway.

Objective: This study evaluated the cost effectiveness of denosumab versus alendronate for secondary prevention of osteoporotic fractures among post-menopausal women in China.

Methods: A validated individual-level simulation model of osteoporotic fractures in the Chinese setting was adapted. Allowing both treatment discontinuation and waning effects, the analysis aimed to evaluate the incremental cost-effectiveness ratio of denosumab compared to alendronate by simulating a cohort of previously fractured individuals over the residual lifetime from the healthcare system perspective.

Roles of klotho and stem cells in mediating vascular calcification (Review).

Vascular calcification, characterized by the active deposition of calcium phosphate in the vascular walls, is commonly observed in aging, diabetes mellitus and chronic kidney disease. This process is mediated by different cell types, including vascular stem/progenitor cells. The anti-aging protein klotho may act as an inhibitor of vascular calcification through direct effects on vascular stem/progenitor cells with osteogenic differentiation potential.

Curcumin suppresses glioblastoma cell proliferation by p-AKT/mTOR pathway and increases the PTEN expression.

Background: Glioblastoma (GB) is the most common neoplasm in the brain. Curcumin, as a known polyphenolic compound extracted from turmeric, is a chemotherapy used in some cancer treatments in China. However, the effect of curcumin on the survivability of GB cells remains to be elucidated.

Captopril Attenuates the Upregulated Connexin 43 Expression in Artery Calcification.

Objective: Vascular calcification is commonly observed in atherosclerosis and diabetes. The renin-angiotensin II system is associated with the regulation of arterial stiffening. The aim of this study was to examine whether the angiotensin-converting enzyme inhibitors captopril attenuates artery calcification.

Vildagliptin and G-CSF Improved Angiogenesis and Survival after Acute Myocardial Infarction.

Background: Myocardial infarction (MI) is one of the most important diseases that has stimulated interest in understanding cardiac function recovery. SDF-1 is a chemotactic factor and a pro-angiogenic molecule; SDF-1 degradation is inhibited by dipeptidyl peptidase-4 (DPP4) inhibitors, such as vildagliptin. We investigated whether vildagliptin affects angiogenesis in MI and improves cardiac function recovery.

Losartan Inhibits Vascular Calcification by Suppressing the BMP2 and Runx2 Expression in Rats In Vivo.

The blockade of renin-angiotensin II system has been shown to reduce morbidity and mortality in hypertension, atherosclerosis, diabetes and chronic kidney disease. Since vascular calcification (VC) is commonly found in these diseases, the aim of this study was to examine whether or not losartan, a widely used angiotensin II receptor blockers, inhibits VC in rats in vivo. A rat model of VC was generated by treating rats with a combination of warfarin and vitamin K1.

In this study, we aimed to determine the effects of TMP on angiotensin II (Ang II)-induced hypertrophy in neonatal rat cardiomyocytes and its possible mechanisms of action.

Endothelin-1 stimulates the expression of L-type Ca2+ channels in neonatal rat cardiomyocytes via the extracellular signal-regulated kinase 1/2 pathway.

The cardiac L-type Ca(2+) channel current (I(Ca,L)) plays an important role in controlling both cardiac excitability and excitation-contraction coupling and is involved in the electrical remodeling during postnatal heart development and cardiac hypertrophy. However, the possible role of endothelin-1 (ET-1) in the electrical remodeling of postnatal and diseased hearts remains unclear. Therefore, the present study was designed to investigate the transcriptional regulation of I(Ca,L) mediated by ET-1 in neonatal rat ventricular myocytes using the whole-cell patch-clamp technique, quantitative RT-PCR and Western blotting.

Macrophages overexpressing VEGF target to infarcted myocardium and improve neovascularization and cardiac function.

Background: Clinical trials of vascular endothelial growth factor (VEGF) gene therapy have proven that VEGF has beneficial effects on the ischemic heart disease; however, the lack of a delivery system targeted to the injured myocardium reduces the local therapeutic efficacy of VEGF and increases its possible adverse effects. This study was performed to determine if macrophages transfected with human VEGF165 could incorporate into blood vessels and target to ischemic myocardial tissue to induce neovascularization and improve cardiac function.

Methods: Macrophages, macrophages transfected with hVEGF165 or phosphate buffered saline (PBS) were injected intravenously into the mice immediately after coronary artery ligation.
