Osteo-Progenitors in Vascular Calcification

Osteoprotegerin: osteo-vascular connection.

[Vascular calcification in CKD].

As doenças cardiovasculares (DCV) constituem a principal causa de mortalidade em pacientes com doença renal crônica (DRC).1 O risco de óbito por DCV nessa população chega a ser 10 a 30 vezes maior que aquele observado na população geral. Esse aumento da mortalidade também ocorre em pacientes nos estágios precoces da DRC,2 assim como naqueles submetidos a transplante renal.3 A alta prevalência d...

Inflammation and Vascular Calcification Causing Effects of Oxidized HDL are Attenuated by Adiponectin in Human Vascular Smooth Muscle Cells

The role of oxidized high-density lipoprotein (oxHDL) and the protective effects of adiponectin in terms of vascular calcification is not well established. This study was conducted to investigate the effects of oxHDL with regards to inflammation and vascular calcification and to determine the protective role of adiponectin in attenuating the detrimental effects of oxHDL. Cell viability, mineral...

Inhibition of Phosphate-Induced Vascular Smooth Muscle Cell Osteo-/Chondrogenic Signaling and Calcification by Bafilomycin A1 and Methylamine.

BACKGROUND/AIMS Excessive phosphate concentrations trigger vascular calcification, an active process promoted by osteoinduction of vascular smooth muscle cells (VSMCs) with increased expression and activity of transcription factor RUNX2 (Core-binding factor α1, CBFA1), alkaline phosphatase (ALPL), TGFß1, transcription factor NFAT5, and NFAT5-sensitive transcription factor SOX9. The osteoinducti...

Vascular calcification in dialysis patients.

Renal osteodystrophy, vascular disease and mortality are believed to be linked in patients with chronic kidney disease (CKD), although to date most of the evidence is based only on statistical associations. The precise pathophysiology of vascular calcification in end stagerenal disease (ESRD) is unknown, but risk factors include age, hypertension, time on dialysis, and, most significantly, abno...
