Insights

Vascular calcification (VC) is increasing with aging populations. The Silent Information Regulator (SIRT) family shows promise in treating VC by targeting cellular aging mechanisms.

Area of Science:

  • Biomedical Science
  • Molecular Biology
  • Gerontology

Background:

  • Vascular calcification (VC) prevalence rises with population aging, affecting individuals with hypertension, diabetes, and chronic kidney disease.
  • VC involves abnormal calcium phosphate deposition in vascular walls, representing a form of vascular aging with no current pharmacological treatments.
  • The Silent Information Regulator (SIRT) family (SIRT1-SIRT7) comprises deacetylases crucial for cellular processes including aging and metabolism, earning them the name 'longevity proteins'.

Purpose of the Study:

  • To explore the therapeutic potential of the SIRT family in mitigating vascular calcification.
  • To investigate the mechanisms by which SIRT proteins may suppress VC, including their role in cellular aging pathways.

Main Methods:

  • Review of existing literature on SIRT family functions and their involvement in vascular aging and calcification.
  • Analysis of studies demonstrating the effects of SIRT activation or modulation on cellular processes relevant to VC.

Main Results:

  • SIRT proteins can alleviate vascular aging by inhibiting inflammation, reducing endoplasmic reticulum stress, and lowering mitochondrial oxidative stress.
  • SIRT family members, particularly SIRT1, SIRT2, SIRT3, SIRT6, and SIRT7, have shown potential in promoting DNA damage repair, a key factor in suppressing VC.
  • These mechanisms collectively contribute to the suppression of vascular calcification.

Conclusions:

  • The SIRT family holds significant therapeutic promise for treating vascular calcification.
  • Targeting SIRT pathways may offer a novel pharmacological strategy to combat VC and associated vascular aging.

Atherosclerosis III: Management

Management of atherosclerosis involves an integrated strategy encompassing pharmacological treatment, surgical interventions, lifestyle changes, and nutrition therapy to address the multifactorial nature of the disease.Pharmacological TherapyA cornerstone of atherosclerosis management is the use of pharmacological agents. Statins, such as atorvastatin, are pivotal in inhibiting HMG-CoA reductase, an enzyme that catalyzes an initial step in cholesterol synthesis in the liver. This reduction in...

Atherosclerosis I: Introduction

Atherosclerosis is a progressive disorder characterized by the buildup of plaques on the arterial inner wall, causing them to narrow and harden over time. These plaques comprise lipids, calcium, blood components, carbohydrates, and fibrous tissue. The process primarily affects the intima of large and medium-sized arteries, reducing blood flow in any artery.Etiology and risk factorsThe cause of atherosclerosis is multifactorial, involving a complex interplay among endothelial injury, lipid...

Peripheral Artery Disease III: Interprofessional Care

Peripheral Artery Disease (PAD) is characterized by narrowed arteries that diminish blood flow to the extremities. Effective management of PAD requires an interprofessional approach involving various healthcare professionals. The critical aspects of interprofessional care for PAD patients focus on risk factor modification, drug therapy, exercise therapy, nutrition therapy, critical limb ischemia care, and interventional radiology and surgical procedures.The primary treatment goal for PAD...

Antihypertensive Drugs: Vasodilators

Vasodilators, primarily affecting the smooth muscles within arterial and venous walls, are commonly used for hypertension treatment. Medications such as minoxidil and hydralazine primarily target arteries and arterioles, while sodium nitroprusside acts on arterioles and venules. Minoxidil, functioning as a prodrug, is metabolized by hepatic sulfotransferase into its active form, minoxidil sulfate, after oral administration. This metabolite binds to the sulfonylurea receptor (SUR) component of...

Mechanism of Angiogenesis01:10

Mechanism of Angiogenesis

Blood vessel formation starts early during embryonic development, around day 7. In the extraembryonic yolk sac, mesodermal precursor cells called hemangioblast proliferate and differentiate into angioblast. Angioblasts express vascular endothelial growth factor receptor 2 or VEGFR2, which binds VEGF-A, a proangiogenic factor, guiding blood vessel formation. VEGF signaling promotes angioblasts to form a blood island in the developing embryo. Angioblasts further differentiate, giving rise to...
