A heterogeneous family of water-soluble structural proteins found in cells of the vertebrate lens. The presence of these proteins accounts for the transparency of the lens. The family is composed of four major groups, alpha, beta, gamma, and delta, and several minor groups, which are classed on the basis of size, charge, immunological properties, and vertebrate source. Alpha, beta, and delta crystallins occur in avian and reptilian lenses, while alpha, beta, and gamma crystallins occur in all other lenses.
A subclass of crystallins that provides the majority of refractive power and translucency to the lens (LENS, CRYSTALLINE) in VERTEBRATES. Alpha-crystallins also act as molecular chaperones that bind to denatured proteins, keep them in solution and thereby maintain the translucency of the lens. The proteins exist as large oligomers that are formed from ALPHA-CRYSTALLIN A CHAIN and ALPHA-CRYSTALLIN B CHAIN subunits.

Decreased heat stability and increased chaperone requirement of modified human betaB1-crystallins. (1/136)

PURPOSE: To determine how deamidation and partial loss of the N- and C-terminal extensions alter the heat stability of betaB1-crystallin. METHODS: Human lens betaB1, a deamidated betaB1, Q204E, and alphaA-crystallins were expressed. Truncated betaB1 was generated by proteolytic removal of part of its terminal extensions. The aggregation and precipitation of these proteins due to heating was monitored by circular dichroism and light scattering. The effect of heat on the stability of both monomers and oligomers was investigated. The flexibility of the extensions in wild type and deamidated betaB1 was assessed by 1H NMR spectroscopy. RESULTS: With heat, deamidated betaB1 precipitated more readily than wild type betaB1. Similar effects were obtained for either monomers or oligomers. Flexibility of the N-terminal extension in deamidated betaB1 was significantly reduced compared to the wild type protein. Truncation of the extensions further increased the rate of heat-induced precipitation of deamidated betaB1. The presence of the molecular chaperone, alphaA-crystallin, prevented precipitation of modified betaB1s. More alphaA was needed to chaperone the truncated and deamidated betaB1 than deamidated betaB1 or truncated betaB1. CONCLUSIONS: Deamidation and truncation of betaB1 led to destabilization of the protein and decreased stability to heat. Decreased stability of lens crystallins may contribute to their insolubilization and cataract formation.  (+info)

Quantification of chick lens alphaA- and delta-crystallins in experimentally induced ametropia. (2/136)

PURPOSE: The role of the lens in experimentally induced ametropia is not known. A recent study of the chick lens demonstrated optical quality deterioration with the induction of refractive errors, without alteration in lens morphology, size or shape. A change in lens gradient of refractive index (which is dependent on alpha-, beta-, and delta-crystallin concentration and arrangement), could underlie this observation. The purpose of this work was to quantify the concentrations of alphaA- and delta-crystallin in lenses from chick eyes with induced high myopia or hyperopia. METHODS: White Leghorn chicks were unilaterally fitted on the day of hatching either with translucent plastic goggles to induce form-deprivation myopia (n=21) or with +15 D defocus goggles to induce hyperopia (n=14). The ungoggled contralateral eyes were used as controls. The chicks were refracted twice, once on the day of hatching and again seven days later, using streak retinoscopy. On day 7 chicks were sacrificed, lenses decapsulated, and soluble proteins were isolated. Western blot assays were optimized and used to assess crystallin concentration. RESULTS: Analysis revealed no significant difference in alphaA- or delta-crystallin concentration in lenses from eyes induced with form-deprivation myopia and hyperopia as compared to their respective control eyes. Analysis of the difference in medians of delta-crystallin between the control and treated groups of the myopia and hyperopia experiments revealed significance (p=0.030). CONCLUSIONS: This study suggests that with the induction of ametropia, the increased lens spherical aberration previously noted is not due to a change in the absolute concentration of lens alphaA- or delta-crystallin. However, results suggest that the myopic and hyperopic treatments had different effects on lens delta-crystallin concentration. Further investigation is necessary to expand the current knowledge of the role played by the lens in experimental ametropia.  (+info)

Morphological characterization of the Alpha A- and Alpha B-crystallin double knockout mouse lens. (3/136)

BACKGROUND: One approach to resolving some of the in vivo functions of alpha-crystallin is to generate animal models where one or both of the alpha-crystallin gene products have been eliminated. In the single alpha-crystallin knockout mice, the remaining alpha-crystallin may fully or partially compensate for some of the functions of the missing protein, especially in the lens, where both alpha A and alpha B are normally expressed at high levels. The purpose of this study was to characterize gross lenticular morphology in normal mice and mice with the targeted disruption of alpha A- and alpha B-crystallin genes (alpha A/BKO). METHODS: Lenses from 129SvEvTac mice and alpha A/BKO mice were examined by standard scanning electron microscopy and confocal microscopy methodologies. RESULTS: Equatorial and axial (sagittal) dimensions of lenses for alpha A/BKO mice were significantly smaller than age-matched wild type lenses. No posterior sutures or fiber cells extending to the posterior capsule of the lens were found in alpha A/BKO lenses. Ectopical nucleic acid staining was observed in the posterior subcapsular region of 5 wk and anterior subcapsular cortex of 54 wk alpha A/BKO lenses. Gross morphological differences were also observed in the equatorial/bow, posterior and anterior regions of lenses from alpha A/BKO mice as compared to wild mice. CONCLUSION: These results indicated that both alpha A- and alpha B-crystallin are necessary for proper fiber cell formation, and that the absence of alpha-crystallin can lead to cataract formation.  (+info)

Reduced survival of lens epithelial cells in the alphaA-crystallin-knockout mouse. (4/136)

alphaA-Crystallin (alphaA) is a molecular chaperone expressed preferentially in the lens. alphaA transcripts are first detected during the early stages of lens development and its synthesis continues as the lens grows throughout life. alphaA(-/-) mouse lenses are smaller than controls, and lens epithelial cells derived from these mice have diminished growth in culture. In the current work, we tested the hypothesis thatalphaA prevents cell death at a specific stage of the cell cycle in vivo. Seven-day-old 129Sv (wild-type) and alphaA(-/-) mice were injected with 5-bromo-2'-deoxyuridine (BrdU) to label newly synthesized DNA in proliferating cells. To follow the fate of the labeled cells, wholemounts of the capsule epithelial explants were made at successive times after the BrdU pulse, and the labeling index was determined. Immunofluorescence and confocal microscopy showed that both wild-type and alphaA(-/-) cells had a 3-hour labeling index of 4.5% in the central region of the wholemount, indicating that the number of cells in S phase was the same. Twenty-four hours after the pulse, individual cells labeled with BrdU had divided and BrdU-labeled cells were detected in pairs. The 24-hour labeling index in the wild-type lens was 8.6%, but in the alphaA(-/-) lens it was significantly lower, suggesting that some of the cells failed to divide and/or that the daughter cells died during mitosis. TUNEL labeling was rarely detected in the wild-type lens, but was significant and always detected in pairs in the alphaA(-/-) wholemounts. Dual labeling with TUNEL and BrdU also suggested that the labeled cells were dying in pairs in the alphaA(-/-) lens epithelium. Immunolabeling of wholemounts with beta-tubulin antibodies indicated that the anaphase spindle in a significant proportion of alphaA(-/-) cells was not well organized. Examination of the cellular distribution of alphaA in cultured lens epithelial cells showed that it was concentrated in the intercellular microtubules of cells undergoing cytokinesis. These data suggest that alphaA expression in vivo protects against cell death during mitosis in the lens epithelium, and the smaller size of the alphaA(-/-) lens may be due to a decrease in the net production of epithelial cells.  (+info)

Alteration of protein-protein interactions of congenital cataract crystallin mutants. (5/136)

PURPOSE: A recent study demonstrated the presence of protein-protein interactions among lens crystallins in a mammalian cell two-hybrid system assay and speculated about the significance of these interactions for protein solubility and lens transparency. The current study extends those findings to the following crystallin genes involved in some congenital cataracts: CRYAA (R116C), CRYAB (R120G), and CRYGC (T5P). METHODS: A mammalian two-hybrid system was used to assay the protein-protein interactions. Congenital cataract crystallin genes were cloned and fused into the two-hybrid system vectors (target and prey proteins). Together, with the third vector containing a reporter gene, chloramphenicol acetyltransferase (CAT), they were cotransfected into human HeLa cells. The presence of protein-protein interactions and the strength of these interactions were assayed by CAT ELISA. RESULTS: The pattern of changes in protein-protein interactions of those congenital cataract gene products with the three major crystallins, alphaA- or alphaB-, betaB2-, and gammaC-crystallins, differed. For the T5P gammaC-crystallin, most of the interactions were decreased; for the R116C alphaA-crystallin, the interactions with betaB2- and gammaC-crystallin decreased and those with alphaB-crystallin and heat-shock protein (Hsp)27 increased; and for the R120G alphaB-crystallin, the interactions with alphaA- and alphaB-crystallin decreased, but those with betaB2- and gammaC-crystallin increased slightly. An attempt was made to interpret the results on the basis of conformational change and disruption of dimeric interaction involving beta-strands. CONCLUSIONS: The results clearly indicate that crystallin mutations involved in congenital cataracts altered protein-protein interactions, which may contribute to decreased protein solubility and formation of cataract.  (+info)

Immunological detection of D-beta-aspartate-containing protein in lens-derived cell lines. (6/136)

PURPOSE: Although the presence of biologically uncommon D-beta-aspartate (D-beta-Asp) in lens protein is thought to be related to aging, we recently found this isomer in lens alphaA-crystallin from human newborns. The objective of this study was to examine whether D-beta-Asp occurs in protein from lens-derived cell lines. METHODS: We examined the expression of D-beta-Asp-containing protein in the lens-derived cell lines alphaTN4-1 and N/N1003A, by western blot and immunoprecipitation analysis using a polyclonal antibody against Gly-Leu-D-beta-Asp-Ala-Thr-Gly-Leu-D-beta-Asp-Ala-Thr-Gly-Leu-D-beta-Asp-Ala-Thr (peptide 3R), which corresponds to three repeats of positions 149-153 in human alphaA-crystallin. The anti-peptide 3R antibody, prepared in a previous study, is a useful tool for investigating D-beta-Asp-containing peptides. RESULTS: Western immunoblot and immunoprecipitation analysis showed that a 50 kDa protein in N/N1003A cells was strongly immunoreactive with the anti-peptide 3R antibody. Antibodies against alphaA- and alphaB-crystallin also stained this protein. On the other hand, the alphaTN4-1 cell line only expressed proteins of about 20 kDa, which also reacted to antibodies against alphaA-crystallin and alphaB-crystallin. CONCLUSIONS: The results indicate that the N/N1003A cell line expressed a 50 kDa D-beta-Asp-containing protein, which may share a common amino acid sequence with alphaA- and alphaB-crystallin.  (+info)

Induction of the differentiation of lentoids from primate embryonic stem cells. (7/136)

PURPOSE: To produce lens cells from primate embryonic stem (ES) cells in a reproducible, controlled manner. METHODS: Cynomologus monkey ES cells were induced to differentiate by stromal cell-derived inducing activity (SDIA). The lentoids produced by this treatment were processed for immunohistochemical and immunoblotting analysis. The effect of varying the concentration of fibroblast growth factor (FGF)-2 and the density of the ES colonies plated during the differentiation process were also examined. RESULTS: After a 2- to 3-week induction period, lentoids were produced by a subpopulation of ES colonies. Western blot analysis and immunohistochemistry revealed that these lentoids expressed alphaA-crystallin and Pax6. The number of lentoids resulting from treatment increased with increasing FGF-2 concentration and plated colony density. CONCLUSIONS: The differentiation of primate ES cells into lentoids can be achieved by treatment with SIDA. ES cells can be used to facilitate a greater understanding of the mechanisms functioning in differentiation in vivo and in vitro.  (+info)

Pathogenesis of axonal dystrophy and demyelination in alphaA-crystallin-expressing transgenic mice. (8/136)

We recently described a transgenic mouse strain overexpressing hamster alphaA-crystallin, a small heat shock protein, under direction of the hamster vimentin promoter. As a result myelin was degraded and axonal dystrophy in both central nervous system (especially spinal cord) and peripheral nervous system occurred. Homozygous transgenic mice developed hind limb paralysis after 8 weeks of age and displayed progressive loss of myelin and axonal dystrophy in both the central and peripheral nervous system with ongoing age. Pathologically the phenotype resembled, to a certain extent, neuroaxonal dystrophy. The biochemical findings presented in this paper (activity of the enzymes superoxide dismutase, catalase and transglutamase, myelin protein zero expression levels and blood sugar levels) confirm this pathology and exclude other putative pathologies like Amyothrophic Lateral Sclerosis and Hereditary Motor and Sensory Neuropathy. Consequently, an excessive cytoplasmic accumulation of the transgenic protein or a disturbance of the normal metabolism are considered to cause the observed neuropathology. Therefore, extra-ocular alphaA-crystallin-expressing transgenic mice may serve as a useful animal model to study neuroaxonal dystrophy.  (+info)

α-Crystallin, a member of small heat shock protein (sHsp) family, is comprised of αA and αB subunits and acts as a molecular chaperone by interacting with unfolding proteins to prevent their aggregation. The αA-crystallin homopolymer consists of 30-40 subunits that are undergoing dynamic exchange. α-Crystallin and αA-crystallin are poorer chaperones in the presence of the crowding agent, dextran. Using fluorescence resonance energy transfer, it is shown that the αAcrystallin subunit exchange rate strongly increased with temperature. Binding of reduced ovotransferrin to αA-crystallin markedly decreases the rate of subunit exchange, as does the presence of dextran. In addition, in the presence of dextran the effect of reduced ovotransferrin on decreasing the rate of subunit exchange of αA-crystallin is stronger than in the absence of dextran. Under the conditions of molecular crowding, the αA-crystallin subunit exchange rate is not temperature-dependent. The exchange rate of αA-crystallin

Purpose: : In our previous studies, we have demonstrated that alpha-crystallins can negatively regulate stress-induced apoptosis through suppression of the ERK-mediated pathway and activation of the AKT signaling pathway. In the present study, we present evidence to show that alpha-crystallins can regulate the ATR-p53 pathway to prevent UVA-induced apoptosis. Methods: : UVA was used to irradiate human lens epithelial cells stably expressing vector, alphaA, and alphaB. Western blot analysis was used for detection of ATR, CHK1/2 and p53 activation. Reporter gene activity assay was used to explore the transactivity of p53. Hoechst staining was used for apoptosis assay. Results: : Human lens epithelial cells expressing either alphaA- or alphaB-crystallin are substantially resistant to UVA-induced apoptosis. UVA-induces activation of ATR and CHK1/2 kinases to activate p53 in vector-transfected cells. However, in alphaA- or alphaB-crystallin-transfected cells, activation of ATR, CHK1/2 kinases and p53 ...

Abstract: : Purpose: To examine the dependence of lens cell signaling pathways on αA-crystallin and determine whether this novel function for αA-crystallin may be related to its association with α6 integrin. Methods: Mouse lenses obtained from wild type or αA knockout lenses were microdissected into epithelial and cortical fiber fractions. Immunoblot analysis with antibodies to activated forms of specific cell signaling proteins (Src, p38, ERK and JNK) was performed. Analysis of these cell signaling pathways was also performed with control mouse lens cultures and those transfected with wild type αA-crystallin or the R116C αA-crystallin mutant. The association of αA-crystallin with α6 integrin in mouse epithelial and cortical fiber fractions was analyzed by immunoprecipitation with antibodies to α6 integrin followed by immunoblotting for αA-crystallin. Similar studies were performed with chicken embryo lenses microdissected into central and equatorial epithelia, cortical and nuclear ...
Discussion. The data presented here indicate that heat incubation produces structural and functional changes in renatured a-, aA-, and aB-crystallins as well as in the native a-crystallin. The chain like structures observed in the 65 °C transmission electron micrographs may indicate the particles formed after heat incubation have a greater propensity to interact with each other than the native particles. These chains could also be artifacts of the negative staining process, however.. There are major differences in the heat-induced secondary structural transitions that separate the native a-crystallin from the other a-crystallins. Renatured a-crystallin exhibits more severe structural changes that are observable at lower incubation temperatures than the native a-crystallin. The effects of heat incubation on chaperone-like activity are also completely opposite, with the native a-crystallin samples showing an improvement and renatured a-crystallin samples showing a progressive decline in activity ...

Cultivate your understanding and knowledge of what the research on trust-building transparency is telling us and how we can begin to apply key learnings within our organizations.
On the first day of work for 2016, Mandaue City Mayor Jonas Cortes called on City Hall workers to continue advocating for transparency and excellence in their jobs.
The chaperone-like protein alpha-crystallin is a approximately 35 subunit hetero-oligomer consisting of alphaA and alphaB subunits in a 3:1 molar ratio and has the function of maintaining eye lens transparency. We studied the thermal denaturation of alpha-crystallin by differential scanning calorimetry (DSC), circular dichroism (CD), and dynamic light scattering (DLS) as a function of pH. Our results show that between pH 7 and 10 the protein undergoes a reversible thermal transition. However, the thermodynamic parameters obtained by DSC are inconsistent with the complete denaturation of an oligomeric protein of the size of alpha-crystallin. Accordingly, the CD data suggest the presence of extensive residual secondary structure above the transition temperature. Within the pH range from 4 to 7 the increased aggregation propensity around the isoelectric point (pI approximately 6) precludes observation of a thermal transition. As pH decreases below 4 the protein undergoes a substantial unfolding. ...
Human alpha-crystallins were separated from fetal, young, senile nondiabetic and diabetic lenses. The effects of aging and diabetes mellitus were studied by fluorescence measurements, including emission maximum, quantum yield and polarization, using both intrinsic probes (tryptophan and non-tryptophan) and extrinsic probes [4-(N-iodoacetoxy)N-methylamino-7-nitrobenz-2-oxa-1,3-diazole (IANBD) and 6-(p-toluidinyl)naphthalene-2-sulfonate (TNS)]. Results indicate that diabetic effects (glycation and aggregation) give fluorescence change to a far greater extent than that of aging. This was demonstrated by a large decrease in tryptophan quantum yield and an increase in non-tryptophan quantum yield, and also by a decrease in polarization of non-tryptophan. The sulfhydryl (SH)-specific probe IANBD shows a blue-shift in emission maximum, a decrease in intensity and an increase in polarization. The hydrophobic probe TNS shows a decrease in both intensity and polarization. These results suggest that tryptophan
The molecular chaperone alphaB-crystallin has emerged as a target for cancer therapy due to its expression in human tumors and its role in regulating tumor angiogenesis. alphaB-crystallin also reduces neuroinflammation, but its role in other inflammatory conditions has not been investigated. Here, we examined whether alphaB-crystallin regulates inflammation associated with tumors and ischemia. We found that CD45(+) leukocyte infiltration is 3-fold increased in tumors and ischemic myocardium in alphaB-crystallin-deficient mice. Notably, alphaB-crystallin is prominently expressed in CD11b(+) Gr-1(+) immature myeloid cells (IMCs), known as regulators of angiogenesis and immune responses, while lymphocytes and mature granulocytes show low alphaB-crystallin expression. alphaB-Crystallin deficiency results in a 3-fold higher accumulation of CD11b(+) Gr-1(+) IMCs in tumors and a significant rise in CD11b(+) Gr-1(+) IMCs in spleen and bone marrow. Similarly, we noted a 2-fold increase in CD11b(+) ...
Mutations in the small heat shock proteins α-crystallins have been linked to autosomal dominant cataracts in humans. Extensive studies in vitro have revealed a spectrum of alterations to the structure and function of these proteins including shifts in the size of the oligomer, modulation of subunit exchange and modification of their affinity to client proteins. Although mouse models of these mutants were instrumental in identifying changes in cellular proliferation and lens development, a direct comparative analysis of their effects on lens proteostasis has not been performed. Here, we have transgenically expressed cataract-linked mutants of αA- and αB-crystallin in the zebrafish lens to dissect the underlying molecular changes that contribute to the loss of lens optical properties. Zebrafish lines expressing these mutants displayed a range of morphological lens defects. Phenotype penetrance and severity were dependent on the mutation even in fish lines lacking endogenous α-crystallin. The ...
Description: The heat-shock proteins (HSPs) belong to a larger group of polypeptides, the stress proteins, that are induced in various combinations in response to environmental challenges and developmental transitions. Synthesis of the small (27-kD) HSP has been shown to be correlated with the acquisition of thermotolerance. The deduced 199-amino acid HSP27 protein shows sequence similarity to mammalian alpha-crystallins. Approximately 20% of its residues are susceptible to phosphorylation. The HSP27 gene, which is mapped to 7q11.23 and has 3 exons1, produced a 2.2-kb transcript in an in vitro transcription assay. Decreasing ROS in cells expressing mutant huntingtin, HSP27 protects cells against oxidative stress2. In other words, HSP27 is a suppressor of polyglutamine (polyQ)-mediated cell death3. Furthermore, MAPKAPK5 is a major stress-activated kinase that can phosphorylate HSP27 in vitro.. Primary Antibody. ...

Ample evidence suggests that oxidative stress and other external stressors contribute to retinal and retinal pigment epithelium (RPE) pathology, as implicated in diseases like age-related macular degeneration. Therefore the understanding of cellular protection against these insults is of therapeutic importance. We adapted two approaches for studying the mechanisms of macular and retinal degeneration. In one, the contribution and significance of these pathologic processes was investigated by use of cultured human and mouse RPE. In the in vivo counterpart studies, we assessed the importance of alpha-crystallins in the retina (and RPE) in models using knockout mice and cobalt chloride injections. In addition to alpha-crystallins, we looked at other oxidative stress protectants of the cell and examined the redox regulation and antioxidant functions mediated by hepatocyte growth factor (HGF). These studies have greatly contributed to the elucidation of the pathways involved in retinal dysfunction and ...

The ocular lens is one of two lenses in the optical train of a microscope, the other being the objective lens. Located in the eyepiece, the ocular lens is the nearest lens to the observer's eye providing additional magnification and directing the image into the observer's eye.Total MagnificationThe total magnification of a microscope is the product of the magnification of the ocular lens and the objective lens. For example, a 10x ocular lens and a 40x objective lens produce a total magnification of 400x.Monocular vs. Binocular MicroscopesMonocular microscopes have one ocular lens, while binocular microscopes have two ocular lenses--one for...

Figure 2. Medians of normalized data for αA-crystallin from treated (OD) and control (OS) lens samples. A: The OS and OD group medians were 1.01 and 1.05 respectively. Statistical analysis (Wilcoxon Signed Rank Test, p=0.90) revealed no significant difference in αA-crystallin concentration in lenses from form-deprived myopic (OD) and control (OS) eyes. B: The OS and OD group medians were 1.24 and 1.37 respectively. Statistical analysis (Wilcoxon Signed Rank Test, p=0.54) revealed no significant difference in αA-crystallin concentration in lenses from eyes induced with hyperopia (OD) versus control eyes (OS). Statistical analysis (Mann-Whitney, p=0.70) revealed no significance in the difference of medians between the myopic and hyperopic study.. ...
What Is Cataract? Cataract is the loss of transparency of the natural lens in the eye. The lens becomes transparent, frosted or stained glass, and complaints about vision begin. Objects appear as amorphous or fuzzy. Eye fatigue and headache occurs.. The structure of the innate lens in the eye consists of protein and water. The special sequence of the protein ensures that the lens is transparent and transparent. Over the years, small protein molecules begin to clump and eventually lose their lens transparency. When this turbidity covers the entire lens so that it cannot pass the light, mature cataracts occur.. Why Do Cataracts Occur ...

So if CEOs are starting to embrace social concepts for their businesses then that means the leadership model is starting to change in these organizations…or at least its starting to get very stressed. At the core of this change though is the concept of transparency. The software that enables social business has inherent transparency built in but is that enough? Unfortunately no, just because you enable information flow doesnt mean that it will actually flow anywhere. Underneath the software theres a need for a culture of transparency, which is fundamentally different from what often happens in businesses today. Transparency is build on trust, or maybe trust is built on transparency…frankly I dont know which comes first, theyre inexorably linked in my mind. I suppose I could have titled this Creating a Culture of Trust just as easily as transparency. Building an organization of trust requires free and open access to information and a culture that encourages openness (which is IMHO a ...
