Fraction C4 (100 mg) was passed over a Sephadex LH-20 column (30 mm × 800 mm, 80 g) and then eluted with MeOH (500 mL) to obtain compound 20 (15 mg). Fraction E3 (1 g) was subjected to chromatography on ODS (30 mm × 150 mm, 50 g) and then eluted successively with solvents AZD6244 price of decreasing polarity (MeOH/H2O, 4:6 600 mL−6:4 600 mL−7:3 600 mL−9:1 600 mL−1:0 600 mL) to yield seven fractions, E3-1−E3-7. Compound 21 (8 mg) was obtained as granulated crystal from E3-6. Fractions F (18 g), G (15 g), H (20 g), and I (20 g) were subjected to chromatography on ODS (50 mm ×

250 mm, 250 g) and then eluted successively with solvents of decreasing polarity (MeOH/H2O, 3:7 3 L−5:5 3 L−7:3 3 L−9:1 3 L−1:0 3 L) to yield 11 fractions, F1−F11, eight fractions, G1−G8, seven fractions, H1−H7, and

eight fractions, I1−I8. Compound 1 (10 mg) was obtained as granulated crystal from F-5. Isolation of the following 15 compounds was performed by preparative HPLC: compounds learn more 2 (18 mg; tR 75.0 min), 12 (30 mg; tR 38.9 min), 13 (20 mg; tR 46.8 min), and 14 (60 mg; tR 53.5 min) were isolated from fraction D3 (500 mg) by HPLC system I; compound 18 (4 mg; tR 41.8 min) was isolated from fraction A2 (60 mg) by HPLC system VI; compounds 3 (15 mg; tR 70.3 min), 4 (15 mg; tR 45.8 min), 5 (14 mg; tR 58.9 min), and 6 (14 mg; tR 65.9 min) were isolated from fraction I4 (200 mg) by HPLC system II; compounds 7 (40 mg; tR 33.5 min) and 8 (60 mg; tR 49.6 min) were isolated from

If the glucoevatromonoside inhibit the Na+K+ATPase, a reversion of the viral inhibition by cells exposure to culture medium containing an increased amount of K+ would be expected. Therefore, MEM was modified to contain 27 mM of potassium (5 times more than in the usual MEM = 5.4 mM). When Vero cells were infected and remained in this modified

MEM (lane 6), the HSV replication occurred characteristically suggesting that the K+ supplementation GW786034 order did not cause any alterations to the host cells, and consequently to the virus replication. In the same way, when the infected cells were treated with glucoevatromonoside and remained in the modified medium (lane 7), the viral protein levels were not inhibited. Furthermore, the treatment with glucoevatromonoside at 0.26 μM (IC100)

using the plaque reduction assay performed with K+ supplementation reestablished 22% of the viral replication capacity (data not this website shown), so these results indicated that the ion K+ is required to HSV-1 replication confirming the results obtained by Nagai et al. (1972). Still striving to elucidate the mechanism of antiherpes activity of glucoevatromonoside, its ability to interfere on virus release was investigated through the determination of intracellular and extracellular HSV-1 titers. Digitoxin, an inhibitor of this stage (Su et al., 2008), was used as a positive control. Every glucoevatromonoside tested concentrations significantly (p < 0.0001) reduced the extracellular

and intracellular virus titers confirming the inhibition of this step of virus replication (data not shown). Farnesyltransferase For example, the lower tested concentration (0.065 μM) reduced the extracellular and intracellular virus titers more than 99.99% (a reduction of 4.8 Log) and 90% (a reduction of 1.6 Log), respectively. In the same way, the percentages of virus release in the presence of different concentrations of glucoevatromonoside and digitoxin were calculated. These compounds inhibited HSV-1 release in a concentration-dependent manner. However, the glucoevatromonoside at its IC50/2 (0.065 μM) was more effective (99.7% of viral release inhibition) than the digitoxin at its IC50/2 (0.17 μM. (76% of viral release inhibition). It is well known that HSV infect epidermis and mucosae cells, and a rapid viral cell-to-cell spread is very important to the establishment of productive primary or recurrent infections in humans (Nyberg et al., 2004). The effect of different concentrations (0.015–0.25 μM) of glucoevatromonoside on HSV-1 cell-to-cell spread was evaluated through a viral plaque size reduction assay, and the results showed a significant (p < 0.001) reduction in the areas of formed viral plaques (from 56% to 98%), when compared to those formed in viral control (data not shown). This effect could be a consequence of the inhibition of viral release.

5, 0.05, 0.005 and 0.0005, respectively), and measured luciferase activity after 1, 2, 3, 4, 7 and 10 days. We did not test a lower infectious doses of 100 TCID50 per well, since at such a low dose stochastic effects would start to play an unacceptably large role, resulting in only 50% of the tested wells being infected. For comparison, infections were also performed using rgEBOV-eGFP, using eGFP fluorescence as a read-out, and rgEBOV-WT, using CPE as a read-out. For rgEBOV-eGFP, the first isolated eGFP-positive cells appeared after 2 days in wells receiving the highest dose, and after 4 days using

102 TCID50 (Fig. 3A). However, the eGFP-positive cells were initially very rare and locating them required extensive scanning of the well. A robust eGFP-signal throughout most of the well became apparent after 3 to 4 days using higher doses Bosutinib chemical structure (104 and 103 TCID50), but only after 7 days at lower doses (102 TCID50). Similar results were obtained using rgEBOV-WT, with mild isolated CPE becoming apparent between 3 and 7 days post-infection, depending on the infectious dose, and clear CPE throughout the well being visible at day 4 post-infection using the highest dose, and 7 to 10 days post-infection for the other doses (Fig. 3B). In contrast, an increase in reporter activity was already detected using rgEBOV-luc2

for all infectious doses at day 1 Trametinib post-infection (Fig. 3C). When determining the Z′-factor (Zhang et al., 1999), infectious doses of 103 TCID50 or higher yielded Z′-factors of >= 0.5 already at day 1, indicating a very robust assay, whereas the lower doses of 102 and 101 TCID50 yielded a Z′-factor of >= 0.5 at days 2 and 3 post-infection,

respectively (Fig. 3D). When comparing this to the results obtained with rgEBOV-eGFP and rgEBOV-WT, it becomes apparent that rgEBOV-luc2 allows much quicker turnaround times for screening assays, and represents an extremely robust assay even at low infectious doses (Fig. 3D). For comparison, all drug-screening efforts with eGFP-expressing EBOV have thus far used high infectious doses (MOI = 5), with readout 2 days post-infection (Panchal et al., 2010 and Panchal et al., 2012). As a proof-of-concept that rgEBOV-luc2 is feasible for use as an antiviral www.selleck.co.jp/products/erastin.html screening tool, we assessed the effect of two well-characterized neutralizing antibodies as well as the effect of a DsiRNA directed against the viral polymerase L. For testing of the neutralizing antibodies, 100 TCID50 (equivalent to an MOI of 0.005) of rgEBOV-luc2 were preincubated with the previously characterized neutralizing antibodies 133/3.16 and 226/8.1 or the non-neutralizing antibody 42/.37, and then used to infect Vero cells. After two days, reporter activity was measured. As expected, there was a clear drop in reporter activity for both neutralizing antibodies, with 226/8.1 showing a 2.

We have previously argued that oculomotor involvement in spatial working memory is task-specific (Ball et al., 2013). While eye-abduction reduces performance on the Corsi Blocks task (where locations are directly indicated), it has no effect on Arrow Span (where locations are symbolically indicated by the direction of an arrow; Shah & Miyake, 1996). We therefore do not claim that the oculomotor system will contribute to encoding and maintenance during all forms of spatial memory task. Instead, we argue the oculomotor system

contributes to optimal spatial memory during encoding and maintenance specifically when the to-be-remembered locations are directly indicated by a change in visual salience, but not when memorized locations are indirectly indicated by the meaning of symbolic cues. This interpretation check details of the role of oculomotor involvement in working memory is consistent with previous findings that have demonstrated the oculomotor system mediates orienting to sudden peripheral events, but not endogenous orienting or maintenance of attention in response to symbolic cues ( Smith

et al., 2012). Furthermore, it also provides a means to reconcile apparently conflicting theories of spatial rehearsal in working memory that have attributed maintenance either to oculomotor processes (e.g., Pearson and Sahraie, 2003 and Postle learn more et al., 2006) or to higher-level attentional processes (e.g., Awh, Vogel, & Oh, 2006). We argue that spatial memory tasks in which memoranda are directly Metformin cost signaled by a change in visual salience involve a critical contribution from the oculomotor system during the encoding and maintenance of to-be-remembered location, while spatial memory tasks in which locations are indirectly signaled by the meaning of symbolic cues predominantly utilize higher-level attentional processes for encoding and rehearsal. The results of Experiment 3 clearly demonstrate that although the oculomotor system contributes to the encoding and maintenance of

spatial locations in working memory, there is no evidence that the ability to plan and execute eye-movements to the memorized locations is necessary for subsequent accurate retrieval. This result can be related to so-called “looking at nothing” debate in the literature, which has focused on the experimental observation that participants frequently make regular eye-movements to empty regions of space that were previously occupied by salient visual stimuli (e.g., Altmann, 2004 and Richardson and Spivey, 2000). This has been interpreted as demonstrating that eye-movements form part of integrated mental representations that include visual and semantic properties of encoded stimuli (Ferreira et al., 2008, Richardson et al., 2009 and Spivey et al., 2004).

Chlorophyll extract was measured as fluorescence and converted to concentration using spinach extract standards. Rock surface area was determined by water volume displacement ( Cooper and Testa, 2001) and epilithic algal biomass reported as μg Chl a cm−2 rock. Leaf material

was processed within a few days of collection to determine mass loss and fungal colonization from each stream site. Leaves were removed from each bag and gently rinsed with deionized water to remove sandy debris. From each leaf bag, ergosterol content (as an indication of fungal biomass) and organic leaf decay rates were determined. Ergosterol concentration (μg Ergosterol mg−1 ash-free dry weight (AFDW) leaf) was measured from 30 haphazardly collected hole punches of leaf tissue. Ergosterol was extracted from leaf punches by incubating in methanol for 2 h followed Apoptosis inhibitor by potassium hydroxide hydrolysis at 80 °C (Newell et al., 1988). Next, sterols were isolated through a pentane extraction at 21 °C. Pentane soluble sterol extracts were dried under a constant stream of N2 gas and re-dissolved in methanol for high pressure liquid chromatography (HPLC) analysis. The separation module (Waters 2695) injected 100 μl of solution through the column (Novapak C18) at a rate of 1.5 ml min−1. The Waters 2998 detector was set

at an absorbance of 282λ. Retention times and concentrations were compared to a pure ergosterol standard (Fluka HPLC grade > 95%; Newell et al., 1988). For leaf loss rates, leaves were dried in an oven at 60 °C until constant weight was reached. Leaf weights were corrected for the 30

this website hole punches taken for ergosterol. Dry leaves were ground and a subsample taken to determine AFDW (i.e., leaf organic content) by ashing in a muffle oven for 5 h at 550 °C. Sugar maple leaf decay rates (k) were calculated for each point using the negative natural log of the percent AFDW remaining at the end of the incubation ( Petersen and Cummins, 1974). Dissolved O2 and N2 concentrations from leaf incubations were determined using membrane inlet mass spectrometry (MIMS) from N2:Ar and O2:Ar ratios (Kana et al., 1994). Ar ratios were converted to concentrations using gas saturated water standards at 20 and 30 °C L-NAME HCl and by applying Henry’s law with published gas constants for Ar, N2, and O2 (Lide and Frederikse, 1995 and Wilhelm et al., 1977). O2 and N2 flux rates were calculated as the difference between initial and final gas concentrations divided by the incubation time. Leaf biofilm oxygen consumption (e.g., O2 uptake; R) and denitrification rates (e.g., N2 flux) were expressed as μg gas h−1 g−1 AFDW leaf. Prior to analysis, parameters were grouped as follows: (1) landscape, (2) water quality, (3) DOM characteristics, and (4) benthic. One N2 flux measurement was removed as an outlier prior to analysis because this point had a z-score < −4 (i.e., greater than 4 standard deviations way from the mean) and poor analytical reproducibility on multiple sample injections.

Some studies on the western Alps, for example, show that repeated prescribed burning with a short fire return

interval may have negative effects on fauna ( Lemonnier-Darcemont, 2003 and Lyet et al., 2009), and favour alien vegetation encroachment in the short-term ( Lonati et al., 2009). Fire has been a driver of landscape evolution and a mirror of human activities in the Alpine region. This review paper is intended to assist in creating and shaping the future through understanding fire history of the Alps and its fire traditions, as well as its specificities. Due to vulnerability of high mountain environments, the Alpine vegetation can be used as an indicator for global change and climate warming in particular (Pauli et al., 2003). For example, the check details advent of a new generation of large wildfires at the Alpine belt could mirror a more general trend towards increasing global warming. The climate warming recorded in the Alpine region from 1890 to 2000 results in double the one assessed at global level (Böhm et al., 2001); the environmental impact brought by a further increase of air temperature might lead to very serious consequences, e.g., affecting the water cycle, the occurrence of avalanches, floods and landslides, the ecological heritage, GSK2118436 mouse the vertical shift of the tree line (Grace et al., 2002), and worsening fire

severity. In this key, the role of the Alps in monitoring climate change evolution is particularly valuable in investigating potential human-induced, and human-affecting, developments, so strictly associated to the Anthropocene. Current global processes, chiefly climate and land use Tyrosine-protein kinase BLK changes, suggest that a complete removal of such

a disturbance from the Alpine area is neither feasible nor advisable. Consequently, we are likely to be forced again to live with fire and to apply traditional knowledge to the principles of fire – and land – management, namely creating resilient landscapes, adapted communities and adequate fire management policies (Dellasala et al., 2004). The unevenness of human population density in the Alpine region is a key issue in defining ad hoc management strategies. On the one hand, land abandonment of marginal areas, alongside climate anomalies, is leading to a new generation of unmanageable large fires (third fire generation sensu Castellnou and Miralles, 2009), where lack of accessibility and fuels build-up are the main constraints, with a greater effect than the often blamed climate change. This will pose a challenge in the future, for instance when shrinking government budgets might result in less capacity of fire services. Furthermore, unbalanced fire regimes such as fire exclusion or very frequent surreptitious use of fire could determine a loss of both species richness and landscape diversity, as it is happening with alpine heathlands ( Lonati et al., 2009 and Borghesio, 2014). Using planned fire for land management and fire prevention ( Fernandes et al.

73m2BS (mL/min/1,73 m2Body Surface).6 Data with homogeneous distribution were shown as mean and standard deviation. All others were shown as median and range. Student’s t-test for paired samples was employed to compare variables with normal distribution, and the Wilcoxon test was used to compare non-normal distribution variables. The latter was also employed to compare the microalbuminuria levels before and after

the substitution of celecoxib to enalapril. The chi-squared test was used to compare the findings in UDE in symptomatic patients during indomethacin and celecoxib use. The study was approved by local ethics committee. Twenty patients were included, of whom 12 were females. Follow-up time was 10.1 ± 5.2 years, age at diagnosis had a median of 17.5 months (3–178) and at last evaluation was 14.0 ± 5.3 years. Five patients

were born from consanguineous parents and two patients were siblings. VX-809 solubility dmso Seven patients, five of whom females, presented with polyhydramnio and/or prematurity, characteristics of neonatal BS. Neurosensorial deafness was observed in two patients (one female), and they are classified as BS with deafness. Eleven patients showed characteristics of classic BS. No patient presented with hypocalciuria, thus excluding the diagnosis of Gitelman syndrome. Seventeen patients received indomethacin for 5.9 ± 5.3 years in a dosage of 2.1 ± 0.6 mg/Kg/day divided in three doses. An increase was observed in height-for-age selleck chemicals llc Z-score, from -3.3 ± -2.1 to -2.2 ± 1.2 (p = 0.01), and in weight-for-age Z-score, from median = -2.9 (-5.7 – 2.5) to median = -1.05 (-4.9- 2.5) (p = 0.0004), without a significant change in the creatinine clearance, which varied from crotamiton median

= 105 (64-277) to median = 144 (71-279) mL/min/1.73m2BS (p = 0.34); and with metabolic and electrolyte stability. However, four patients had hyperfiltration at the beginning and eight presented hyperfiltration at the end of the treatment. Seven of 17 patients had GI symptoms, and UDE evidenced gastritis in three cases and gastric ulcer, a severe finding, in four. Nineteen patients received celecoxib, during a median of 35 months (8-144). An increase was observed in height-for-age Z-score from -2.4 ± -1.7 to 1.8 ±1.3 (p = 0.02) and in weight-for-age Z-score from -1.3 ± 1.5 to -0.81 ± 1.2 (p = 0.01), as well as a reduction in creatinine clearance from 147 ± 52 to 119 ± 31 mL/min/1.73m2BS (p = 0.04). Nine patients presented with hyperfiltration at the beginning of treatment; at the end, hyperfiltration was detected in only two patients. Seven of 19 patients presented GI symptoms, but UDE evidenced mild gastritis in three cases and no case of ulcer. Comparing indomethacin with celecoxib, positive findings in UDE were more present in indomethacin group, although not significant (p = 0.06); however, indomethacin was associated with more severe compromise. During the treatment with celecoxib, no patient developed gastric ulcer.

Among these 178 patients, the highest eosinophil percentage in BALF was 2.6% (Table 1); in contrast, the eosinophil percentage in peripheral blood was highly variable and reached a maximum of 22.0% in one case. We categorized each subject into one of three groups (<4%, 4%–10%, and ≥10%) according to the peripheral

blood eosinophil percentage as described by Renston et al.8; we then evaluated the presence of several allergic diseases on the basis of medical records (Table 1). Although some patients with peripheral blood eosinophilia had comorbidities, such as asthma or allergic rhinitis, others did not have additional clinically apparent diseases. Percentage of peripheral blood eosinophils of <4% or ≥4% were not associated Selleck Akt inhibitor with the stage of sarcoidosis according to the results of the chi-square test. Several studies have paid special attention to eosinophil percentage in BALF in patients with sarcoidosis, and eosinophils represented over 1% of all the inflammatory Olaparib molecular weight cells only in a few cases.1, 2 and 3 Similarly, among the 178 patients examined in this retrospective study, the highest eosinophil percentage in BALF was 2.6%. To the best of our knowledge, only three sarcoidosis cases with elevated eosinophil percentage in BALF have been reported,4, 5 and 6 and in these

cases, the authors speculated the co-occurrence of chronic

eosinophilic pneumonia. In contrast, Renston et al. reported that 41% of patients with sarcoidosis showed an increase of peripheral blood eosinophil percentage more than 4%.8 In the population used in this project, peripheral blood eosinophilia, IKBKE which was defined as >4%, was observed in 35.4% patients (63/178). Some patients had comorbidities (i.e. asthma, allergic rhinitis) that would potentially cause eosinophilia. However, others did not show any evidence of comorbidities on the basis of medical records. Considering both the report by Renston et al. and the present findings, sarcoidosis might be directly associated with peripheral eosinophilia in some patients. That is, peripheral eosinophilia in patients with sarcoidosis might not always indicate coexisting allergic diseases. The mechanism underlying the co-occurrence of sarcoidosis and BALF eosinophilia is unclear. Tani et al. demonstrated that concentrations of IL-4, IL-5, and IFN-γ were increased in BALF4 in their case. Shijubo et al. discussed the possibility that factors related to migration of both CD4-positive lymphocytes and eosinophils, such as lymphocyte-chemoattractant factor (LCF) and IL-2,5 were involved. In these two previous reports, there was no description of the clinical course of concomitant sarcoidosis or BALF eosinophilia.

The Cys–AG73 peptide (CGG–RKRLQVQLSIRT) and a scrambled Cys–AG73T control peptide (CGG–LQQRRSVLRTKI) were synthesized manually using the 9-fluorenylmethoxycarbonyl (Fmoc)-based solid-phase strategy and were prepared in the COOH terminal

amide form and purified by reverse-phase high-performance liquid chromatography. Dox-encapsulating liposomes composed of DSPC, DSPE–PEG2000–OMe, and DSPE–PEG2000–Mal at a molar ratio of 94:4:2 were prepared by a reverse-phase evaporation method and a remote loading method. For coupling, AG73 peptide at a molar ratio of 2-fold DSPE–PEG2000–Mal was added to the Dox-encapsulating liposomes, and the mixture was incubated for 24 h at 4 °C to conjugate the cysteine of the Cys–AG73 peptide with the maleimide of the Dox-encapsulating liposomes using a thioether bond. Dinaciclib solubility dmso The resulting AG73 peptide-conjugated CDK inhibitor Dox-encapsulating liposomes (AG73–Dox) were passed through a Sephadex G-50 spin column to remove any excess peptide. AG73–Dox was modified with

6 mol% PEG and 2 mol% peptides. The particle size and zeta potential of the liposomes were measured using NICOMP 380 ZLS (Particle Sizing Systems, Santa Barbara, CA, USA). 293T human embryonic kidney carcinoma cells that stably overexpressed syndecan-2 (293T-Syn2) and murine colorectal carcinoma cells (colon26) were cultured in DMEM that was supplemented with 10% FBS, penicillin (100 U/ml), streptomycin (100 μg/ml), and puromycin (0.4 or 100 μg/ml) at 37 °C in a humidified 5% CO2 atmosphere. Male BALB/c mice (6 weeks old) were purchased from Tokyo Laboratory Animals Science Co., Ltd. (Tokyo, Japan). Animal use and relevant experimental procedures were approved by the Tokyo University of Pharmacy and Life Science Committee on the Care and Use of Laboratory Animals. The

intracellular uptake of liposomes was determined by flow cytometry analysis [9]. 293T-Syn2 cells (1×105 cells/well) were seeded in a 24-well plate and incubated for 48 h at 37 °C in 5% CO2. Colon26 cells (5×104 cells/well) were also seeded in a 24-well plate and incubated for 24 h at 37 °C in 5% CO2. The medium was then replaced with Dox-encapsulating liposomes (Dox–PEG), AG73–Dox, or Dox-encapsulating Non-specific serine/threonine protein kinase AG73T peptide-modified liposomes (AG73T–Dox) that were diluted with culture medium for a final Dox concentration of 20 μg/ml. The plates were incubated for 1 h at 37 °C. The medium was removed; subsequently, each cancer cell line was washed with phosphate-buffered saline (PBS), and the cell samples were examined by flow cytometry using an FACScan (Becton Dickinson, San Jose, CA, USA). Cell-associated Dox was excited with an argon laser (488 nm). Data were collected in 10,000 gated events and analyzed with the CELL Quest software program. 293T-Syn2 cells (2 or 5×104 cells/well) were seeded in a 24-well plate and incubated for 48 h at 37 °C in 5% CO2.

Primers used for PCR amplification were osgshsp-F TACCTgTTTgAgTgCggTgACT and osgshsp-R gATACgACgCATggACTggA; they were designed

from four peptide sequences obtained by mass spectrometry of protein (Supplementary Fig. 2A, boxed region) and matched those of crystallin. Putative crystallin sequences were examined for homogeneity by published crystallin sequences with Blast (http://www.ncbi.nlm.nih.gov/BLAST). RACE-PCR was carried AZD2281 purchase out as previously described [29]. Based on the verified sequence of the 979 bps fragment of crystallin cDNA, two primers crystallin-5RACE, osgshsp-a387 gCggTAggAgTTgCTCC, osgshsp-a516 CCAgAgggTgggCACATC, and crystallin-3RACE, osgshsp-s300 TCgCTgggATACCTggAgC and osgshsp-s600, gATCTgCCTgTATgAgCTCTCCg were PCR-amplified and cloned for the 5′ and 3′ ends, respectively. Two adapter primers for both ends were provided in the Marathon cDNA Amplication Kit (Clontech, Mountain View, CA, USA). The (RACE)-PCR thermal cycle profile was as follows: 94 °C for 1 min; 30 s at 94 °C, 4 min at 72 °C, and 10 min at 72 °C for 30 cycles; followed by an extension at 72 °C for 10 min. The amplified

fragment was verified with subcloning into a pCR II vector for sequencing. To minimize polymerization errors during PCR, a proofreading polymerase was employed in PCR reactions. Real time reverse transcription (RT)-PCR was used to quantify the Selleckchem Gemcitabine expression of mRNA for crystallin with expression of actin as reference. The primers osgshsp-F TACCTgTTTgAgTgCggTgACT and osgshsp-R gATACgACgCATggACTggA were used to amplify a 130 bp fragment of grouper crystallin. A standard curve was constructed by

serially diluting a linearized plasmid containing the open reading frame of grouper crystallin. Grouper beta actin primers were applied to normalize the starting quantity of RNA. Typical profile times used were initial step, 95 °C for 15 min, followed by a second step at 94 °C for 15 s, 60 °C for 30 s and 72 °C for 30 s for 40 cycles with melting curve analysis. The level of target mRNA was normalized to the level of actin and compared to control (healthy grouper) and the values were calculated by the 2−ΔΔCT method. To elucidate the evolutionary history of crystallin, novel crystallin sequences were identified Mannose-binding protein-associated serine protease in zebrafish and eight mammalian species, and used to explore the phylogenetic relationships of the crystallin gene family. A neighbor-joining phylogenetic tree was produced by the MEGA3.1 program [30] on the basis of a ClustalW alignment of the nucleotide sequences of the open-reading frames along with all known complete sequences of crystallin cDNA with the complete deletion of gaps for 1000 bootstrap replications. Numbers indicated bootstrap confidence values through 1000 replications; only bootstrap values over 70% are exhibited. RAW 264.
