Patients with COPD have evidence of greater cutaneous elastin degradation than age- and smoking-matched controls. Our findings represent evidence of enhanced degradation of elastin outside of the lung in COPD, and we believe that systemic elastin degradation may be a novel systemic feature of COPD. Furthermore, we have found increased expression of MMP-9 in the skin of patients with COPD, a protease implicated in the pathogenesis of emphysema, and these data suggest a role in systemic elastin degradation in COPD.. Elastin degradation in non-sun-exposed skin was associated with both emphysema severity and aortic pulse wave velocity. We speculate that the systemic elastin degradation demonstrated in the skin may also occur in other elastin-rich structures, such as the walls of large conduit arteries, and is an explanation for the increased arterial stiffness in COPD.. Development of emphysema, arterial stiffness and elastin degradation are features of normal ageing, reinforcing the importance of ...
Mice deficient in the macrophage elastase matrix metalloproteinase-12 (MMP-12) do not develop cigarette smoke induced emphysema or show high levels of macrophage accumulation in the lung on exposure to cigarette smoke. However, monocyte migration to the lung in MMP-12 deficient mice can occur in the presence of an appropriate stimulus. This study used an in vivo model to investigate that stimulus.. Bronchoalveolar lavage (BAL) fluid from wild-type smoke exposed mice (and not MMP-12 deficient controls) showed monocyte chemotactic activity. MMP-12 itself was not chemotactic. Fractionation of BAL fluid from wild-type mice found that elastin fragments were the only matrix protein fragments present in the chemotactic fraction of the fluid. The use of an elastin fragment antibody resulted in monocyte chemotaxis inhibition, even in the presence of cigarette smoke.. Porcine pancreatic elastase generates a model of emphysema that closely resembles human emphysema. Elastin fragment inhibition by elastin ...
Rationale: After a myocardial infarction, necrosed cardiomyocytes are replaced by fibrotic tissue. Subsequent thinning and expansion of this non-elastic scar contributes to cardiac dilatation and congestive heart failure. We attempted to restore the elastic properties of the scar by implanting the infarct area with cells expressing elastin.. Methods: Full-length elastin cDNA was generated by PCR using the human lung cDNA library, and then transfected (in adenoviral vector) into rat bone marrow stromal cells (BMSCs). Western blot and immuno-staining confirmed expression of elastin protein. Seven days after coronary artery ligation, BMSCs transfected with genes for either adeno-elastin (BMSC+Elastin) or adeno-green fluorescence protein (BMSC), or media (control group) were injected into the infarct area of adult rats (n=8/group).. Results: Over 8 weeks following cell or media implantation, cardiac function (fractional shortening by echocardiography), ventricular volumes, and load independent ...

We demonstrated that PRT-201 fragments elastin, a protein present in blood vessel walls. The fragmentation of elastin in the outside wall of the blood vessel is thought to inhibit formation of neointimal hyperplasia thereby reducing the risk of patency loss. Elastase causes localized fragmentation of elastin protein fibers present in blood vessel walls. The elastin fragments generated by elastase are chemoattractants for scar forming cells, meaning that the fragments attract these scar forming cells, inhibiting their migration to the lumen. The cells recognize the elastin fragments via receptors present on the cell surface that bind to specific elastin fragment sub-types. The importance of elastin fragments in vascular biology, including the response to vascular injury has been established in the scientific literature over three decades. Published academic studies conducted in animals provide evidence that fragmentation of elastin in the outer wall of the blood vessels from administration of ...

The elastin receptor complex contains a component of 67 kilodaltons that binds to a glycoconjugate affinity column containing beta-galactoside residues and is eluted from this column with lactose. This protein component is also released from the surface of cultured chondroblasts by incubation with lactose, and its association with immobilized elastin is inhibited by lactose. Since lactose also blocks elastic fiber formation by cultured chondroblasts, the galactoside-binding property of the elastin receptor is implicated in this process. ...
While characterizing developmental changes in aortic wall composition in sheep, we observed very rapid accumulation of elastin and collagen in the immediate perinatal period. Thoracic aortic elastin content increased by 41%, and collagen content increased by 49% in approximately 1 week, between 140 days gestation and 3 days postpartum (term = 145 days). Even larger changes were observed in the abdominal aorta. Elastin content increased by 66%, and collagen increased by 57%. The pronounced increase in wall tissue accumulation near birth preceded a marked postnatal increase in arterial pressure. We propose that this elastin and collagen accumulation is a preadaptive response in preparation for the later increase in pressure. The prenatal and postnatal events that initiate this synthesis and accumulation are not known. We also found that, in the 3 weeks after this initial rapid increase, accumulation of elastin and collagen was markedly reduced in the abdominal, but not the thoracic, aorta. This ...
Elastomeric proteins are known by their great resilient properties being able to withstand significant deformations without rupture, returning to their original state when the stress is removed. In this family we find elastin like polymers (ELPs) that have the ability to undergo inverse temperature transition1 along with other smart behaviour properties. Furthermore, they present astonishing biocompatibility, making them ideal for a huge range of applications especially in health sciences. Ind this work we have studied the production of GAG220, and ELP composed by the monomer VPAVG, expressed by E. coli. Since GAG220 and the culture medium used were designed by us it is vital to understand the polymer kinetics formation profile in order to identify the peak of production. A set of experiments was planned comprising a screening of the production at different environmental conditions, namely incubation temperature, dissolved oxygen tension and primary carbon source concentration. The results ...
The physical and chemical properties of the mammalian aorta are known to vary as a function of distance from the heart. These properties are highly dependent collagen and elastic fibers. In order to evaluate the mechanisms which regulate the accumulation of these two connective tissue proteins, gene expression was evaluated at both the biosynthetic and messenger RNA levels. Short-term (3 h) explant cultures of the medial portion of four segments of the descending aorta in newborn pigs were incubated in the presence of [3H] proline. Collagen production was quantified by collagenase digestion and elastin production was determined by immunoprecipitation. Between the conus arteriosus and the bifurcation of the iliac arteries, relative collagen synthesis increased 2-fold (from 5.8 to 12.0% of total protein synthesis), while relative elastin synthesis declined 10-fold (from 16.4 to 1.6% of total protein synthesis). Similarly, collagen production increased more than 7-fold (from 6.7 to 49.8 X 10(3) molecules

Ever wondered how to get more elastin in skin without getting those injections? Curious to know how to increase both collagen and eliastin in your skin the chemical free, safe and healthy way?. One thing you should know first though…your skin doesnt stay soft, firm and supple as the years roll by. Why? The main reason - the loss of the two vital skin proteins called collagen and elastin.. This is simply part of the aging process. In your earlier years, the collagen and elastin content of human skin was at high levels.. But now, the loss of collagen and elastin in skin starts appearing. As time slips by, skin starts to sag, develop fine lines and winkles which are all due to a breakdown of those two proteins.. Many people dont know this, but the skincare products advertised that claim to add back elastin in skin dont work. You can apply all the skincare cream that says "collagen elastin added" on the label but youre wasting your time and money.. The reason - those two proteins are much too ...

Chronic obstructive pulmonary disease (COPD) is a major health problem worldwide and is now the third leading cause of death in the United States. There is a lack of therapies that can stop progression of the disease and improve survival. New drug discovery can be aided by the development of biomarkers, which can act as indicators of severity in the course of the disease and responses to therapy. This perspective brings together the laboratory and clinical evidence, which suggest that elastin degradation products can fulfill the need for such a biomarker. Elastin is a recognized target for injury in COPD. The amino acids desmosine and isodesmosine exist only in matrix elastin; can be measured specifically and sensitively in plasma, urine, and sputum; and indicate changes in the systemic balance between elastase activity and elastase inhibition brought on by the systemic inflammatory state. The biomarker levels in sputum reflect the state of elastin degradation in the lung specifically. Clinical ...
The intracellular domains of the membrane-anchoring regions of some precursors of epidermal growth factor (EGF) family members have intrinsic biologic activities. We have determined the role of the human proEGF cytoplasmic domain (proEGFcyt) as part of the proEGF transmembrane-anchored region (proEGFctF) in the regulation of motility and elastinolytic invasion in human thyroid cancer cells. We found proEGFctF to act as a negative regulator of motility and elastin matrix penetration and the presence of proEGFcyt or proEGF22.23 resulted in a similar reduction in motility and elastinolytic migration. This activity was counteracted by EGF-induced activation of EGF receptor signaling. Decreased elastinolytic migratory activity in the presence of proEGFctF and proEGFcyt/proEGF22.23 coincided with decreased secretion of elastinolytic procathepsin L. The presence of proEGFctF and proEGFcyt/proEGF22.23 coincided with the specific transcriptional up-regulation of t-SNARE member SNAP25. Treatment with ...
Having beautiful, smooth and firm skin allows one to feel good about their appearance and have a healthy self-image - qualities that help people live better, longer. To this end, biochemist Dr Chantal Burnison designed the breakthrough ingredient Ethocyn, used in the finest wrinkle creams today. As confirmed by eminent M.D. and skin physiologist Dr. Peter T. Pugliese, "The single most important cause of age related skin wrinkles and sagging is the loss of skin elastin fibers. Everyone, whether female or male, will begin to lose skin elastin fibers at age 25. Elastin fibers are the restorative force in the skin.". Elastin gives the skin resiliency and the ability to stretch and snap back into shape, much like a rubber band. When we are young, our skin has high levels of elastin - on average, 14-18 percent. As we age, our elastin levels naturally decrease. Clinical trials confirm that in patients 40 years and older elastin levels drop to as low as .1% and on average are in the 9% range. For this ...

Collagens and elastin are important proteins that provide skin its firmness and elasticity. Skin care products have incorporated ingredients that indirectly help maintain and generate skin collagens and elastin for the past years. The new trend, on the other hand, is to dig into the cellular level metabolic mechanism of senescent fibroblasts directly. Last year, Induchem companies produced a new complex named Neodermyl, which could provide what skin cells needed to build collagens and elastin.. Neodermyl is Methyl Glucoside Phosphate Proline Lysine Copper Complex. The long name indicates what active ingredients Neodermyl contains. They are three groups of ingredients, each of which is necessary to feed and regulate cellular collagen and elastin synthesis. First, Neodermyl provides MG6P (Methyl-Glucoside-6-Phosphate). MG6P is pre-activated glucose that can feed skin cells with energy without causing harmful glycation. Then, proline and lysine in Neodermyl are amino acids. How proline and lysine ...
Substances like Cynergy TK(TM) that contains functional keratin(TM) can stimulate elastin and collagen re-growth in your skin. For elastin and collagen to grow these proteins have to be stimulated by another substance that is capable of making this production possible.

Researchers from Jefferson Medical College of Thomas Jefferson University, Philadelphia, have developed the first transgenic, or genetically altered, mouse used to study the causes and effects of photoaging on human skin. The mouse line, developed by microinjecting fertlized mouse eggs with human elastin promoter DNA, which produces skin fibers that promote elasticity, has enabled researchers to learn more about how the ultraviolet light causes skin aging and wrinkling.
The artificial elastin 100xELP has high similarity to human elastin and consists of oligomeric repeats of the pentapaptide Val-Pro-Gly-Xaa-Gly (Xaa - any amino acid but proline). Hence it solely consists of units that resemble the hydrophobic domain of natural elastin. Therefore it is not able to be linked to a network. However, 100xELP exhibits a good ability to be solved in aqueous solution depending on the salt concentration and temperature. It can undergo an inverse transition, i.e. the protein is soluble in an aqueous solution below its transition temperature but insoluble above this critical value ...

Introduction: Accelerated arterial stiffening is a common complication of type 2 diabetes that is patho-mechanistically linked to a severely increased cardiovascular risk. Unfortunately, up to date specific strategies to effectively address diabetic vascular stiffening are elusive. The discovery of non-coding microRNAs (miRs) provides new opportunities for innovative therapeutical approaches. Specifically, microRNA-29b may potentially serve as a comprehensive regulator of vascular fibrosis as well as elastin breakdown, both contributing to diabetic arterial stiffness.. Objective: This study was designed to investigate the role of miR-29b as potential mediator and therapeutic target of diabetic aortic stiffness.. Method and Results: Ex vivo mechanical testing of thoracic aortae via pressure myography revealed increased aortic stiffness in diabetic db/db mice. Vascular stiffening was accompanied by increased elastin fragmentation and collagen deposition (EvG and Picrosirius Red staining). qRT-PCR, ...

A study of the affinities for cholesterol from serum lipoproteins by elastin and collagen components of the arterial wall was undertaken. The low-density lipoproteins (LDL) of human serum and very low-density lipoproteins (VLDL) of rabbit serum were incubated with bovine tendon collagen and with porcine aortic elastin. Cholesterol analysis of the elastin residues revealed a significant ability of the elastin to bind the lipoprotein cholesterol. Succinylation of the LDL did not seem to inhibit the amount of cholesterol transfer. The collagen also bound cholesterol but to a lesser extent. A concurrent project of tissue culturing aortas from various animals with primary interest in growth rate was done. A strain of Japanese quail resistant to experimental atherosclerosis (REA) showed significantly less proliferation of cells as compared with a strain susceptible to experimental atherosclerosis (SEA) grown under identical conditions which may suggest something about the genetic predispositions to ...

Melt That Fat Deals contours bodies using two LED lights, one that shrinks fat cells and one that increases collagen and elastin production. The 635nm infrared light penetrates down to fat cells in the waist, hips, thighs, and arms, and creates temporary holes in their membranes. This forces the fat cells to release their stored fatty acids and water and shrink in size, resulting in lost inches. Meanwhile, the 880nm red light spurs the body to increase collagen and elastin production, resulting in tighter skin. The noninvasive treatment doesnt require any downtime because the system includes six large, flexible pads, multiple areas of the body can be treated in one 20-minute session.

Morphology change analysis of aorta images acquired from biological experiments plays a critical role in exploring the relationship between lamina thickness (LT), interlamellar distance (ILD) and fragmentation (furcation points) with respect to pathological conditions. An automated software tool now is available to extract elastic laminae (EL) and measure LT, ILD and fragmentation along their ridge lines in a fine detailed aspect. A statistical randomized complete block design (RCBD) and F-test were used to assess potential (non)-uniformity of LT and ILD along both radial and circumferential directions. Illustrative results for both normotensive and hypertensive thoracic porcine aorta revealed marked heterogeneity along the radial direction in nearly stress-free samples. Quantifying furcation point densities were also found that can offer new information about potential elastin fragmentation, particularly in response to increased loading due to hypertension. Furthermore, when biological ...

The main components responsible for the mechanical behavior of the arterial wall are collagen, elastin, and smooth muscle cells (SMCs) in the medial layer. We determined the structural and mechanical changes in porcine carotid arteries after administration of Triton X-100, elastase, and collagenase using the inflation?deflation test. The arteries were intraluminarly pressurized from 0 to 200 mmHg, and the outer diameter of the artery was measured. The pressure?strain elastic modulus was determined based on the pressure/diameter ratio. The intima?media thickness, wall thickness, thickness of the tunica adventitia layer, and the area fractions of SMCs, elastin, and collagen within the arterial wall (AA(SMC/elastin/collagen, wall)) were measured using stereological methods. The relative changes in the relevant components of the treated samples were as follows: the decrease in AA(SMC, wall) after administration of Triton X-100 was 11% ? 7%, the decrease in AA(elastin, wall) after administration of ...
