Streszczenie:

α-Crystallin is the major protein of the eye lens and a member of the family of small heat-shock proteins. Its concentration in the human eye lens is extremely high (about 450 mg/mL). Three-dimensional structure of native α-crystallin is unknown. First of all, this is the result of the highly heterogeneous nature of α-crystallin, which hampers obtaining it in a crystalline form. The modeling based on the electron microscopy (EM) analysis of α-crystallin preparations shows that the main population of the α-crystallin polydisperse complex is represented by oligomeric particles of rounded, slight

Streszczenie:

Age-related cataract is a result of crystallins, the predominant lens proteins, forming light-scattering aggregates. In the low protein turnover environment of the eye lens, the crystallins are susceptible to modifications that can reduce stability, increasing the probability of unfolding and aggregation events occurring. It is hypothesized that the α-crystallin molecular chaperone system recognizes and binds these proteins before they can form the light-scattering centres that result in cataract, thus maintaining the long-term transparency of the lens. In the present study, we investigated th

α-crystallin is a major structural protein in the eye lenses of vertebrates that is composed of two relative subunits, αA and αB crystallin, which function in maintaining lens transparency. As a member of the small heat-shock protein family (sHsp), α-crystallin exhibits chaperone-like activity to prevent the misfolding or aggregation of critical proteins in the lens, which is associated with cataract disease. In this study, high-purity αA and αB crystallin proteins were expressed from E. coli and purified by affinity and size-exclusion chromatography. The size-exclusion chromatography experime

Streszczenie:

The role of α-crystallin, a small heat-shock protein and chaperone, may explain how the lens stays transparent for so long. α-Crystallin prevents the aggregation of other lens crystallins and proteins that have become unfolded by ‘trapping’ the protein in a high-molecular-mass complex. However, during aging, the chaperone function of α-crystallin becomes compromised, allowing the formation of light-scattering aggregates that can proceed to form cataracts. Within the central part of the lens there is no turnover of damaged protein, and therefore post-translational modifications of α-crystallin

αH-Crystallin, a high molecular weight form of α-crystallin, is one of the major proteins in the lens nucleus. This high molecular weight aggregate (HMWA) plays an important role in the pathogenesis of cataracts. We have shown that the chaperone-like activity of HMWA is 40% of that of α-crystallin from the lens cortex. Refolding with urea significantly increased—up to 260%—the chaperone-like activity of α-crystallin and slightly reduced its hydrodynamic diameter (Dh). HMWA refolding resulted in an increase in chaperone-like activity up to 120% and a significant reduction of Dh of protein parti

Several studies reported that α-crystallin concentrations in the eye lens cytoplasm decrease with a corresponding increase in membrane-bound α-crystallin with age and cataracts.

This study uses the electron paramagnetic resonance (EPR) spin-labeling method to investigate the α-crystallin binding to bovine CM and NM derived from the total lipids extracted from a single lens.

Using a range of different salt conditions, the rate and extent of precipitation of reduced α-lactalbumin have been altered. The interaction of α-crystallin with reduced α-lactalbumin under these various salt conditions was then studied using a range of spectroscopic techniques.

The lens of the eye needs to be completely transparent in order to allow all light entering the eye to reach the retina. This transparency is maintained by the highly ordered structure of the lens proteins the crystallins. Any disruption to the lens proteins can cause an opacity to develop which is known as cataract. During cortical cataract formation there is increased truncation of the lens crystallins. It is believed that overactivation of calcium-dependent cysteine proteases, the calpains, is responsible for the increased proteolysis of the crystallins seen during cataractogenesis. Within

Abstract Alumina (Al2O3) coatings on stainless steel substrates were fabricated by electromagnetically accelerated plasma spraying (EMAPS), which generated a high-velocity pulsed plasma jet of more than 2.5 km/s with a high peak pressure of 1 MPa. High amounts of α-Al2O3 crystalline phase in the raw powder was preserved in the EMAPS coatings where the ratio of α-Al2O3 to γ-Al2O3 was approximately 65:35, which is generally different from the α-Al2O3-rich coatings formed from α-Al2O3 raw powders using conventional spraying methods, such as plasma spraying, detonation gun spraying, and high-veloc

Abstract Nano-dispersed α-Al2O3/YAG composite coatings were successfully obtained by plasma spraying of the granulated Al2O3/Y2O3 powder, and the post heat treatment. The as-sprayed coating was composed of an amorphous phase, metastable Y-Al-O solid solution. After the heat treatment around 1473K, two crystalline phases, α-Al2O3 and YAG, precipitated, so that the fine dispersed Al2O3/YAG composite coatings were formed. The sizes of the precipitates could be widely controlled by time and temperature of the heat treatment. Hardness and wear property were evaluated in this nano-structured CMC coa

Polyamide 6 (PA6) is a semi-crystalline thermoplastic used in many engineering applications due to good strength, stiffness, mechanical damping, wear/abrasion resistance, and excellent performance-to-cost ratio. In this report, two structure-property relationships were explored. First, carbon nanotubes (CNT) and graphene (G) were used as reinforcement molecules in simulated and experimentally prepared PA6 matrices to improve the overall mechanical properties. Molecular dynamics (MD) simulations with INTERFACE and reactive INTERFACE force fields (IFF and IFF-R) were used to predict bulk and You
