elastin

elastin

 [e-las´tin]
a yellow scleroprotein, the essential constituent of elastic connective tissue; it is brittle when dry, but flexible and elastic when moist.

e·las·tin

(ē-las'tin), [MIM*130160]
A yellow elastic fibrous mucoprotein that is the major connective tissue protein of elastic structures (for example, large blood vessels, tendons, ligaments); elastins precursor is proelastin.
Synonym(s): elasticin

elastin

(ĭ-lăs′tĭn)
n.
A protein similar to collagen that is the principal structural component of elastic fibers.

elastin

A fibrous protein which is similar to collagen (in that one-third of the amino acids are glycine) with abundant proline, valine, and arginine, and which is formed by cross-linking small globular subunits to lysine residues. Elastin’s elasticity is ideally suited for its prominent role in arterial walls, vocal cords, alveolar septa, and ligaments, and has an amorphous wavy appearance by light microscopy. Defects in the cross-linking in elastin’s unique beta spiral, as well as increases or decreases in elastin, are implicated in coronary heart disease, emphysema, type-V Ehlers-Danlos syndrome, Menke’s kinky hair disease, pseudoxanthoma elasticum, and X-linked cutis laxa.

(ĕ-las'tin)
A yellow elastic fibrous mucoprotein that is the major connective tissue protein of elastic structures (large blood vessels, tendons, and ligaments).
Synonym(s): elasticin.

elastin

the major protein found in ELASTIC FIBRES, responsible for the extensible and resilient nature of tissues, such as the skin, lung and larger blood vessels.

These collagen peptides boost skin elasticity, reduce eye wrinkle depth up to 20%, and increase pro- collagen and elastin levels.
In order to estimate the mechanical behaviour of elastin-rich fascia and collagen-rich fascia along the vaginal length, comparison has been made from experiments after digesting or removing either collagen or elastin from artery, elastin-rich spleen, and collagen-rich liver [53-55].

It is well-known that MMP2 plays a pivotal role in the pathogenesis of vascular calcification involved in elastin degradation and VSMC transdifferentiation to an osteoblast-like phenotype [19, 33-35].
In excess they lead to oxidative stress, which contributes to health problems, as well as premature skin aging by destroying collagen and elastin. "Sun damage, excessive alcohol intake, and cigarette smoke can produce excessive free radical damage," says Dattner, adding that eating foods rich in antioxidants can help prevent this oxidative damage.
Invigorates dermal circulation and cell turnover boosts collagen and elastin and fortifies skin's immunity to defend against free-radicals that can age skin prematurely.
In control group of calves, elastin was observed in mild amount on 10th day interval, while it was mild to moderate on 20th and 30th day interval.

In addition, stimulation of fibroblasts results in stimulating the synthesis of elastin - the protein responsible for skin firmness and elasticity.
They hypothesized that abnormal elastic fibers accumulated in the dermis can be potent inducers of movement and terminal differentiation of keratinocytes via the 67 kDa protein, an elastin receptor.
