Crystallins: 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.alpha-Crystallins: 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.Lens, Crystalline: A transparent, biconvex structure of the EYE, enclosed in a capsule and situated behind the IRIS and in front of the vitreous humor (VITREOUS BODY). It is slightly overlapped at its margin by the ciliary processes. Adaptation by the CILIARY BODY is crucial for OCULAR ACCOMMODATION.beta-Crystallin B Chain: The basic subunit of beta-crystallins.beta-Crystallin A Chain: The acidic subunit of beta-crystallins.gamma-Crystallins: A subclass of crystallins that found in the lens (LENS, CRYSTALLINE) of VERTEBRATES. Gamma-crystallins are similar in structure to BETA-CRYSTALLINS in that they both form into a Greek key-like structure. They are composed of monomeric subunits.beta-Crystallins: A class of crystallins that provides refractive power and translucency to the lens (LENS, CRYSTALLINE) in VERTEBRATES. Beta-crystallins are similar in structure to GAMMA-CRYSTALLINS in that they both contain Greek key motifs. Beta-crystallins exist as oligomers formed from acidic (BETA-CRYSTALLIN A CHAIN) and basic (BETA-CRYSTALLIN B CHAIN) subunits.alpha-Crystallin A Chain: One of the subunits of alpha-crystallins. Unlike ALPHA-CRYSTALLIN B CHAIN the expression of ALPHA-CRYSTALLIN A CHAIN is limited primarily to the lens (LENS, CRYSTALLINE).alpha-Crystallin B Chain: One of the alpha crystallin subunits. In addition to being expressed in the lens (LENS, CRYSTALLINE), alpha-crystallin B chain has been found in a variety of tissues such as HEART; BRAIN; MUSCLE; and KIDNEY. Accumulation of the protein in the brain is associated with NEURODEGENERATIVE DISEASES such as CREUTZFELDT-JAKOB SYNDROME and ALEXANDER DISEASE.delta-Crystallins: A subclass of crystallins found in the lens (LENS, CRYSTALLINE) in BIRDS and REPTILES. They are inactive forms of the enzyme argininosuccinate lyase.Cataract: Partial or complete opacity on or in the lens or capsule of one or both eyes, impairing vision or causing blindness. The many kinds of cataract are classified by their morphology (size, shape, location) or etiology (cause and time of occurrence). (Dorland, 27th ed)Molecular Sequence Data: Descriptions of specific amino acid, carbohydrate, or nucleotide sequences which have appeared in the published literature and/or are deposited in and maintained by databanks such as GENBANK, European Molecular Biology Laboratory (EMBL), National Biomedical Research Foundation (NBRF), or other sequence repositories.Polymerase Chain Reaction: In vitro method for producing large amounts of specific DNA or RNA fragments of defined length and sequence from small amounts of short oligonucleotide flanking sequences (primers). The essential steps include thermal denaturation of the double-stranded target molecules, annealing of the primers to their complementary sequences, and extension of the annealed primers by enzymatic synthesis with DNA polymerase. The reaction is efficient, specific, and extremely sensitive. Uses for the reaction include disease diagnosis, detection of difficult-to-isolate pathogens, mutation analysis, genetic testing, DNA sequencing, and analyzing evolutionary relationships.alpha 1-Antitrypsin: Plasma glycoprotein member of the serpin superfamily which inhibits TRYPSIN; NEUTROPHIL ELASTASE; and other PROTEOLYTIC ENZYMES.Amino Acid Sequence: The order of amino acids as they occur in a polypeptide chain. This is referred to as the primary structure of proteins. It is of fundamental importance in determining PROTEIN CONFORMATION.Base Sequence: The sequence of PURINES and PYRIMIDINES in nucleic acids and polynucleotides. It is also called nucleotide sequence.Argininosuccinate Lyase: An enzyme of the urea cycle which splits argininosuccinate to fumarate plus arginine. Its absence leads to the metabolic disease ARGININOSUCCINIC ACIDURIA in man. EC 4.3.2.1.Receptors, Adrenergic, alpha: One of the two major pharmacological subdivisions of adrenergic receptors that were originally defined by the relative potencies of various adrenergic compounds. The alpha receptors were initially described as excitatory receptors that post-junctionally stimulate SMOOTH MUSCLE contraction. However, further analysis has revealed a more complex picture involving several alpha receptor subtypes and their involvement in feedback regulation.Hypoxia-Inducible Factor 1, alpha Subunit: Hypoxia-inducible factor 1, alpha subunit is a basic helix-loop-helix transcription factor that is regulated by OXYGEN availability and is targeted for degradation by VHL TUMOR SUPPRESSOR PROTEIN.Cattle: Domesticated bovine animals of the genus Bos, usually kept on a farm or ranch and used for the production of meat or dairy products or for heavy labor.Electrophoresis, Polyacrylamide Gel: Electrophoresis in which a polyacrylamide gel is used as the diffusion medium.Protein Binding: The process in which substances, either endogenous or exogenous, bind to proteins, peptides, enzymes, protein precursors, or allied compounds. Specific protein-binding measures are often used as assays in diagnostic assessments.Recombinant Proteins: Proteins prepared by recombinant DNA technology.Proto-Oncogene Proteins c-maf: Maf proto-oncogene protein is the major cellular homolog of the V-MAF ONCOGENE PROTEIN. It was the first of the mammalian MAF TRANSCRIPTION FACTORS identified, and it is induced in activated T-LYMPHOCYTES and regulates GENETIC TRANSCRIPTION of INTERLEUKIN-4. c-maf is frequently translocated to an immunoglobulin locus in MULTIPLE MYELOMA.Reverse Transcriptase Polymerase Chain Reaction: A variation of the PCR technique in which cDNA is made from RNA via reverse transcription. The resultant cDNA is then amplified using standard PCR protocols.Mutation: Any detectable and heritable change in the genetic material that causes a change in the GENOTYPE and which is transmitted to daughter cells and to succeeding generations.Native Polyacrylamide Gel Electrophoresis: Polyacrylamide gel electrophoresis under conditions in which the components, such as PROTEINS, being separated can remain in their naturally folded state.Models, Molecular: Models used experimentally or theoretically to study molecular shape, electronic properties, or interactions; includes analogous molecules, computer-generated graphics, and mechanical structures.Binding Sites: The parts of a macromolecule that directly participate in its specific combination with another molecule.alpha7 Nicotinic Acetylcholine Receptor: A member of the NICOTINIC ACETYLCHOLINE RECEPTOR subfamily of the LIGAND-GATED ION CHANNEL family. It consists entirely of pentameric a7 subunits expressed in the CNS, autonomic nervous system, vascular system, lymphocytes and spleen.Immunoglobulin Light Chains: Polypeptide chains, consisting of 211 to 217 amino acid residues and having a molecular weight of approximately 22 kDa. There are two major types of light chains, kappa and lambda. Two Ig light chains and two Ig heavy chains (IMMUNOGLOBULIN HEAVY CHAINS) make one immunoglobulin molecule.RNA, Messenger: RNA sequences that serve as templates for protein synthesis. Bacterial mRNAs are generally primary transcripts in that they do not require post-transcriptional processing. Eukaryotic mRNA is synthesized in the nucleus and must be exported to the cytoplasm for translation. Most eukaryotic mRNAs have a sequence of polyadenylic acid at the 3' end, referred to as the poly(A) tail. The function of this tail is not known for certain, but it may play a role in the export of mature mRNA from the nucleus as well as in helping stabilize some mRNA molecules by retarding their degradation in the cytoplasm.Cloning, Molecular: The insertion of recombinant DNA molecules from prokaryotic and/or eukaryotic sources into a replicating vehicle, such as a plasmid or virus vector, and the introduction of the resultant hybrid molecules into recipient cells without altering the viability of those cells.Protein Conformation: The characteristic 3-dimensional shape of a protein, including the secondary, supersecondary (motifs), tertiary (domains) and quaternary structure of the peptide chain. PROTEIN STRUCTURE, QUATERNARY describes the conformation assumed by multimeric proteins (aggregates of more than one polypeptide chain).Immunoglobulin Heavy Chains: The largest of polypeptide chains comprising immunoglobulins. They contain 450 to 600 amino acid residues per chain, and have molecular weights of 51-72 kDa.

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

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 ...

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

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 ...

PURPOSE: To investigate racial differences of lens transparency properties and the prevalence of lens opacification by age. METHODS: Lenses of randomly selected Asian (1,038 Japanese and 517 Singaporeans) and Caucasian (1,045 Icelanders) subjects were evaluated for their lens transparency property (LTP). The prevalence of lens opacification was determined with a newly proposed WHO cataract classification system. RESULTS: LTP increased with aging for all nationalities. Light scattering intensity was significantly higher in the Singaporeans followed by the Icelandic subjects. The prevalence of cortical opacification in Singaporeans was significantly higher than those of the other nationalities up to the age of 60, and the prevalence in Asians was significantly higher than that in Caucasians aged 60-69. Cortical opacification was more prevalent than the other types for both Japanese and Icelanders in their 50s, 60s and 70s. Regarding the central optical zone, the prevalence in the Singaporeans was ...
