Thermoelasticity of Elastin [PDF]

Nature, 1970
THERE is some controversy about the presence in elastin of an ordered structure1–3. Mammi et al.4 now report evidence for the occurrence of some degree of α-helix conformation in the native protein. The conformation was previously5 observed in soluble elastin; the temperature coefficient of the α-helix had different values in solvents such as water or ...

A mammalian Wnt5a-Ror2-Vangl2 axis controls the cytoskeleton and confers cellular properties required for alveologenesis. [PDF]

, 2020
Alveolar formation increases the surface area for gas-exchange and is key to the physiological function of the lung. Alveolar epithelial cells, myofibroblasts and endothelial cells undergo coordinated morphogenesis to generate epithelial folds (secondary

Matrikines are key regulators in modulating the amplitude of lung inflammation in acute pulmonary infection [PDF]

, 2015
Bioactive matrix fragments (matrikines) have been identified in a myriad of disorders, but their impact on the evolution of airway inflammation has not been demonstrated.

Raman Microscopy at the Organic–Inorganic Interfaces in Human Calcified Aortic Valves Shows the Co‐Existence of Whitlockite Crystals and Carbonated Hydroxyapatite‐Mineralized Collagen Fibrils

Advanced Functional Materials, EarlyView.
This study advances our understanding of aortic valve stenosis by capturing spatially resolved chemical and structural changes at the nanoscale. The findings highlight the potential of combined Raman and electron microscopy for understanding calcification mechanisms across diverse tissue types.

Elastin‐Specific Autoimmunity in Smokers With Thoracic Aortic Aneurysm and Dissection is Independent of Chronic Obstructive Pulmonary Disease

Journal of the American Heart Association: Cardiovascular and Cerebrovascular Disease, 2019
Background Thoracic aortic aneurysm (TAA) and dissection (TAD) are characterized by progressive disorganization of the aortic wall matrix, including elastin, a highly immunogenic molecule.

Plasma Soluble Human Elastin Fragments as an Intra-Aneurysmal Localized Biomarker for Ruptured Intracranial Aneurysm [PDF]

, 2018
Background—Fragmentation of the tunica media is a hallmark of intracranial aneurysm formation, often leading to aneurysmal progression and subsequent rupture.

Cardiac‐Derived ECM Microspheres for Enhanced hiPSC‐CMs Maturation

Advanced Functional Materials, EarlyView.
Cardiac extracellular matrix microspheres derived from decellularized porcine heart provide a biomimetic 3D microenvironment for human induced pluripotent stem cell–derived cardiomyocytes (hiPSC‐CMs). This platform supports short‐ and long‐term culture, enhances structural organization, and promotes electrophysiological and functional maturation of ...

PKCε Increases Extracellular Elastin and Fibulin-5/DANCE in Dermal Fibroblasts

Cellular Physiology and Biochemistry, 2018
Background/Aims: In the earlier study, the selective PKCε activator DCP-LA increased elastic fibres in the dermis of HR-1 hairless mice. As a process of elastic fibre formation, tropoelastin, an elastin monomer, is secreted into the extracellular space ...
