01). Taken together, comparison of the healthy population and HCV genotype 3–infected population does not indicate

BGB324 any evidence of a role for these two SNPs in natural clearance of HCV genotype 3 infection. The SNPs near the IL28B gene on chromosome 19 coding for IFN-λ3 recently reported to be associated with treatment response in HCV have excited clinicians and scientists alike, they have a potential to better identify patients with HCV genotype 1 infection who are likely to benefit from PEG-IFN/ribavirin therapy, and they may reveal mechanisms associated with viral clearance and immunity. In Europe, HCV genotype 2 and 3 can be as prevalent as HCV genotype 1 and although the treatment response for HCV genotype 2 and 3–infected patients

are much better, many patients do not achieve a sustained response after a full course of PEG-IFN/ribavirin therapy. Recent studies of predominantly HCV genotype 2–infected European patients show that the CC genotype at rs12979860 can predict SVR, but this is largely driven by patients LY2606368 molecular weight who do not achieve RVR.15 In studies of HCV genotype 2–infected Asian patients, the rs8099917 TT genotype was not associated with SVR.23 Rauch al.12 have also shown no effect of rs8099917 in HCV genotype 2/3–infected patients in a smaller cohort. Similarly, Montes-Cano et al.16 show an absence of association of rs12979860 with SVR in HCV genotype 2/3–infected patients. In HCV genotype 1–infected patients, the rs12979860 CC genotype shows association with very a high baseline viral load, natural clearance of the virus, and RVR to PEG-IFN/ribavirin therapy in addition to SVR.9, 13, 24 Paradoxically, high baseline viral load has been repeatedly shown to be associated with a poorer SVR. A model that explains the paradoxical effect or association of this genotype with high viral load and better therapeutic response is yet to be suggested. Although our data is taken from two populations of HCV genotype 2–infected and genotype 3–infected patients, we were interested in HCV genotype 3–infected patients for two reasons. First, we had sufficient number of samples and data

from HCV genotype 3–infected patients for statistical analysis, unlike other studies of HCV genotype 2 and 3 studies, in which genotype 2 was predominant.15, 25 Second, the SVR rate among HCV genotype 2–infected patients was high (93%, n = 70), significantly higher than HCV genotype 3–infected patients (80%, P = 0.0055) and the number of patients without SVR was too low for meaningful analysis. We found that in HCV genotype 3–infected patients, the CC genotype at rs12979860 compared to CT/TT, and the TT genotype at rs8099917 compared to TG/GG, are associated with high baseline viral load and RVR, but not SVR. This suggests that HCV genotype 3 patients with the so-called host-responder genotypes are more likely to relapse after an early response.

The increase in serum ALT level at 8 hours after Con A (15 mg/kg) administration was attenuated by an anti-VAP-1 antibody that is known to inhibit adhesive functions but not to interfere with the enzymatic activity of VAP-1.[9] However, the attenuation was only apparent at 8 hours (70% attenuated) but not at 24 hours (Fig. 1B). Consistent with this observation, LY2157299 solubility dmso histological analysis revealed that Con A-induced portal and lobular inflammation was minimally attenuated in anti-VAP-1-treated livers at 8 hours (statistically not significant) (Fig. 2A-D, Table 1). At 24 hours of hepatic injury, blocking lymphocyte recruitment into the liver was not sufficient to affect the overall injury markedly

(Fig. 2E-H, Table 2). Interestingly, some spatial difference occurred. The histological score for periportal inflammation was lower, as was the necrosis of the two rows of hepatocytes adjacent to

the space of Disse (interface) while the lobular inflammation and necrosis were not reduced. VAP-1 functions as an SSAO in addition to an adhesin.[13, 15] The catalytic activity of VAP-1 has been invoked in the induction of various liver diseases.[14, 15] Therefore, we examined whether an enzymatic inhibitor for SSAO can attenuate the hepatic injury derived by Con A. Although EMD 1214063 order there was no statistically significant difference in serum ALT level between the vehicle-treated and SSAO inhibitor-treated group (Fig. 1C), the values were 2,007 ± 391 for vehicle and Con A and 1,433 ± 332 for SSAO inhibitor

and Con A. Inhibiting α4 integrin, however, not only did not inhibit injury, there was a very significant almost 2-fold further increase in injury. Furthermore, anti-α4 antibody induced periportal inflammation that was not induced by Con A alone (Table 1). At 24 hours after Con A, the lobular inflammation was more severe with α4-integrin treatment (Fig. 2E-H, Table 2) and serum ALT levels were higher, particularly at 8 hours, to Con A alone (Fig. 1B). However, these blocking Baf-A1 supplier antibodies themselves did not cause any liver damage and systemic inflammation as shown in serum ALT and lung myeloperoxidase (MPO) level (Supporting Fig. 2). The liver is known to have a large amount of resident mononuclear cells including T cells, natural killer (NK) cells, and NKT cells. A further significant infiltration of mononuclear cells including NK cells and CD3+ lymphocytes and a decrease in NKT cells were noted with Con A (Supporting Fig. 3). Although the mononuclear cell values for anti-α4 and anti-VAP-1 antibody-treated mice were lower, they did not reach significance perhaps because only some subpopulations were decreased while others stayed the same or even increased (Fig. 3A). Indeed anti-VAP-1 antibodies attenuated the increase in CD4+ cells (Fig. 3B), but did not influence the NK and NKT cells (Supporting Fig. 3). There was no change in the number of CD8 T cells (Fig. 3B).

WANG, CHENG WEI TANG Corresponding Author: CHENG WEI TANG Affiliations: West China Hospital Objective: The annual incidence of gastroenteropancreatic neuroendocrine tumors (GEP-NETs) is still unclear in China. The objective of this study is to estimate the incidence of GEP-NETs in Chengdu city, the fourth biggest city of China. Methods: This study estimated the incidence of GEP-NETs in Chengdu city with the database of West China Hospital and population-based data from Chengdu Health Bureau during 2006 – 2010. Among the hospitals with the ability to diagnose GEP-NETs in Chengdu

city, the annual patients in West China Hospital were 25.6%∼28% of those in whole of the PARP inhibitor hospitals during the past five years. GEP-NETs incidence in Chengdu was yielded by the number of annual new patients with GEP-NETs in West China Hospital divided with the 25.6% ∼ 28% population of Chengdu city. Results: GEP-NETs incidence in Chengdu increased 1.89 folds during past 5 years from 1.13/100000 to 2.14/100000, p < 0.05. The average duration of symptom before diagnosis was 15 months. Application of GI-Endoscopy increased during the five years. About 46.4% of GEP-NETs were later stage when diagnosis was made. 77% patients were over 40 years. Proportions of GEP-NETs from most common primary sites were rectum 30.6%, pancreas 23.4%, gastric 13.3%, esophagus 11.3%. Proportions of insulinoma, vipoma and non-functional pancreatic neuroendocrine tumors (P-NETs) were 43.1%, 1.7% and 55.2% separately in the P-NETs. Conclusion: The incidence of GEP-NETs is

increasing in Chengdu area with a population of 14.04 million. There is a distinct epidemiologic profile for each primary site. The delayed diagnosis Galeterone reflects limited medical education regarding GEP-NETs, inadequate disease awareness and paucity of research funding. Key Word(s): 1. GEP-NETs; 2. Incidence; 3.

MicroRNA-148a was described to be down-regulated in several types of solid cancers, while it has not been studied in pancreatic cancer.

Thus, further down-regulation of these miRNAs might facilitate HCC metastasis. Further delineating the prognostic significance of these miRNAs individually or as a signature panel in a larger

cohort may shed light on clinical HCC stratification and prediction of postoperative TAM Receptor inhibitor tumor recurrence in HCC patients. Based on the above findings, we propose a sequential miRNA deregulation model involved in HCC development and metastasis. Because miRNA deregulation is an early event in liver carcinogenesis, accumulation of aberrant miRNA expressions drives HCC formation. The later global miRNA down-regulation exacerbates the preexisting miRNA deregulation and promotes metastasis formation by deregulating critical cell motility–associated pathways, which may consequently result in clonal selection that promotes cancer cells to detach from the primary HCC mass, survive in the blood stream, and form venous metastasis in the veins.

“Bone density disorders are prevalent in patients with chronic liver disease (CLD), who commonly present with hepatic osteodystrophy. However, the relationship between nutritional status and bone mineral density (BMD) has been scarcely studied in CLD. This single-center, cross-sectional study included outpatients consecutively diagnosed

with CLD during a 1.5-year period. The nutritional status was assessed with the Controlling Nutritional Status (CONUT) index; dual-energy X-ray absorptiometry scans and parameters of bone mineral metabolism were carried out. Bone fracture risk was estimated with the World Health Organization FRAX tool. Among the 126 patients recruited (58.7% male), osteopenia

and osteoporosis were present in 31.1% and 10.7%, respectively. The 10-year fracture risk was Decitabine mw significantly higher among women. Malnutrition estimated with the CONUT index was present in 29.9% of patients and was significantly more frequent in cirrhotic patients, 63.4% of whom were malnourished. Malnutrition stage directly correlated with hepatic function as expressed by the Model for End-Stage Liver Disease index. A non-significant relationship between CONUT-assessed nutritional status and BMD was documented. 25-Hydroxyvitamin-D3 (25[OH]-D3) and fracture risk correlated positively with the CONUT stage, and total cholesterol had an inverse relationship with BMD. Malnutrition assessed by the CONUT was very frequent in patients with liver cirrhosis. The CONUT score inversely correlated with liver function, while malnutrition stage directly correlated with BMD, fracture risk and 25(OH)-D3. Total cholesterol showed a negative association with BMD in this population. “

The expression of Sonic Hedgehog (SHH), a ligand of the HH pathway, was analyzed by immunohistochemistry in 84 NAFLD patients with different stages of fibrosis. In these patients, SHH expression increases concomitantly to fibrosis stage, ballooning, Fulvestrant mw portal inflammation, and fibrosis. Interestingly, at the univariate analysis age, body mass index, waist circumference, homeostasis model assessment-insulin resistance, essential hypertension, and fibrosis stage strongly correlated with hepatic expression of

SHH. In HH signaling, the interaction of SHH with the cell surface receptor Patched depresses Smoothened (SMO) activity, leading to nuclear localization of glioblastoma family transcription factors (GLI1, 2, and 3) that regulate the expression of cell-specific target genes.2 Interestingly, Guy and colleagues1 observed a significant correlation between nuclear accumulation of GLI2, liver fibrosis, and other risk factors for NAFLD. Accordingly, we found that GLI2 was overexpressed in liver extracts from rats treated with high fat/high fructose (HF/HFr) diet as compared with standard diet (Fig. 1A). We previously Alvelestat demonstrated that rats fed a HF/HFr diet histologically resemble human NAFLD, developing a rare fibrosis with increased collagen VI.3 Here we show that this dietetic regimen also increases hyaluronic

acid (HA) circulating levels (Fig. 1B). HA, as well as osteopontin, is an important ligand for CD44, a marker of cancer stem cells, whose expression is inhibited by SMO antagonists.4 We hypothesize that an interaction network may exist between HA and HH signaling. This hypothesis is strongly supported by data from Patched1 mutant Oxalosuccinic acid mice (Ptch1+/−), in which the HH pathway is constitutively

activated and displays high levels of circulating HA with respect to Ptch1+/+ mice (Fig. 1c). These results may explain why these mice are susceptible to developing fibrosis in diet-induced NAFLD.5 In conclusion, the relationships between the HH pathway and CD44 ligands, such as HA, may be critical for the comprehension of mechanisms that lead to fibrosis and hepatocellular carcinoma from NAFLD.

“In the March 2013 issue of Hepatology, in the article titled “Inhibition of hedgehog signaling attenuates carcinogenesis in vitro and increases tumor necrosis of cholangiocellular carcinomas” (volume 57, pages 1035-1045; doi: 10.1002/hep.26147), by Mona El Khatib, Anna Kalnytska, Vindhya Palagani, Uta Kossatz, Michael P.

4E). The HPLC www.selleckchem.com/HDAC.html profiles clearly show the metabolites distribution of each fraction and suggest that the bioactive compound(s) may be eluted from 15 to 20 minutes in fraction A (Fig. 4F). In order to identify the bioactive phytocompounds in the A fraction, a total of eight subfractions were further purified by semipreparative HPLC (data not shown). Two major compounds were then isolated

and identified to be the bioactive principles. They are RA and BC (Fig. 4G) by analyzing their mass, 1H-, 13C-, and 2D-NMR data as well as by comparing their 1H-, 13C-NMR data with those of commercial authentic samples (data not shown). We tested next whether authentic RA and BC reproduce the effects observed with the YGW extract by testing a wide range of concentrations for HSC morphologic reversal. Indeed, both RA and BC morphologically reverse activated HSCs to quiescent cells with increased UV-excited autofluorescence at concentrations of 135 and 270 μM (Fig. 5A). Using www.selleckchem.com/products/Nutlin-3.html the concentration of 270 μM, RA and BC are shown to down-regulate α1(I) procollagen 2 to 3-fold and to induce PPARγ 3 to 4-fold (Fig. 5B). Both RA and BC reduce MeCP2 protein level (Fig. 5C) and its enrichment in the Pparγ promoter (Fig. 5D). RA and BC also reduce EZH2 expression

and H3K27me2 at the Pparγ exon (Fig. 5E,F). Collectively, these results support that RA and BC are indeed active phytocompounds that render the YGW’s effect to inhibit Methocarbamol or reverse HSC activation by way of epigenetic derepression of Pparγ. We have previously shown that activation of canonical Wnt signaling underlies HSC activation11 by way of epigenetic repression of Pparγ involving MeCP2 and H3K27me2.16 Thus, we thought epigenetic derepression of Pparγ achieved by RA and BC is due to their ability to inhibit canonical Wnt signaling. Indeed, both RA and BC suppress the expression of Wnt10b and Wnt3a (Fig. 5G), the canonical Wnts up-regulated in HSC activation11 and TOPFLASH activity (Fig. 5H). Expression

of Necdin, which transcriptionally up-regulates Wnt10b,16 is also reduced by RA and BC (Fig. 5G), suggesting that these phytocompounds target the Necdin-Wnt-MeCP2 pathway for reversal of HSC activation. BC is the active ingredient of Sho-Saiko-To, a Japanese herbal medicine that has been tested for its antifibrotic effects in experimental models25 and patients.26 In contrast, studies on the effects of RA on liver fibrosis are limited to a few recent reports.27, 28 In one of these studies, RA was shown to prevent the development of CCl4-induced liver fibrosis in rats.27 As RA is an antioxidant, this effect on CCl4-induced oxidative liver damage and consequent liver fibrosis are rather expected. To extend this observation in a different etiological model, we considered testing the efficacy of RA for inhibiting progression of preexisting cholestatic liver fibrosis induced by BDL in mice.

human PBMC proliferation in mice was determined by flow cytometry with the following mAbs used for PBMC surface staining: allophycocyanin (APC)-H7 antihuman CD3 (clone SK7); APC-conjugated anti-CD4 (clone SK); BD Horizon V450 antihuman CD8 (clone RPA-T8); APC-conjugated antihuman CD11c (clone B-ly6); HU HRZN V500 MAB-conjugated antihuman CD45 (clone H130); Alexa Fluor 488–conjugated antihuman CD56 (clone B159); PerCP-Cy5.5 antihuman CD123 (clone 7G3); fluorescein isothiocyanate–conjugated Lineage cocktail 1 (Lin-1) (anti-CD3, CD14, CD16, CD19, CD20, and CD56); APC-H7 antihuman HLA-DR (clone L243); phycoerythrin Selleckchem Palbociclib (PE)-conjugated antihuman FasL (clone NOK-1); and biotin-conjugated antimouse H-2Db (clone KH95). The biotinylated mAbs were visualized

using PE-Cy7-streptavidin. Each of the above mAbs Romidepsin were purchased from BD Biosciences. PE-conjugated HBV core-derived immunodominant CTL epitope (HBcAg93)18 (Medical & Biological Laboratories Co., Ltd., Nagoya, Japan). Dead cells identified by light scatter and propidium iodide staining were excluded from the analysis. Flow cytometry was performed using a FACSAria II flow cytometer (BD Biosciences), and results were analyzed with FlowJo software (Tree Star, Inc., Ashland, OR). DCs can be classified into two main subsets: plasmacytoid DCs (pDCs) and myeloid DCs (mDCs).19, 20 pDCs were defined as CD45+Lin-1−HLA-DR+CD123+ cells, whereas mDCs were Parvulin defined as CD45+ Lin-1−HLA-DR+CD11c+ cells. Histochemical analysis and immunohistochemical staining using an antibody against human serum albumin (HSA; Bethyl Laboratories, Inc., Montgomery, TX), an antibody against hepatitis B core antigen (HBcAg) (Dako Diagnostika, Hamburg, Germany) and antibody against Fas (BD Biosciences, Tokyo, Japan) were performed as described previously.16 Immunoreactive materials were visualized using a streptavidin-biotin staining kit (Histofine SAB-PO kit; Nichirei, Tokyo, Japan) and diainobenzidine. For the terminal deoxynucleotidyl transferase dUTP nick end labeling (TUNEL)

assay in sliced tissues, we used an in situ cell death detection kit (POD; Roche Diagnostics Japan, Tokyo, Japan). Mice were sacrificed by anesthesia with diethyl ether, and livers were excised, dissected into small sections, and then snap-frozen in liquid nitrogen. Total RNA was extracted from cell lines using the RNeasy Mini Kit (Qiagen, Valencia, CA). One microgram of each RNA sample was reverse transcribed with ReverseTra Ace (Toyobo Co., Tokyo, Japan) and Random Primer (Takara Bio Inc., Kyoto, Japan). We analyzed the messenger RNA (mRNA) levels of Fas by reverse-transcription PCR, as previously reported, using Fas forward primer 5′- GGGCATCTGGACCCTCCTA-3′ and Fas reverse primer 5′- GGCATTAACACTTTTGGACGATAA-3′. mRNA expression levels of Fas and interferon-stimulated genes (ISGs) were compared using Mann-Whitney’s U test and unpaired t tests. A P value less than 0.

Some limitations of this study deserve attention. The study does not allow determining whether the observed reactions are indeed a response to a change of residence or rather a response to a change of routine associated with a change of residence. However, in both cases, novelty is the common Selleck Trichostatin A denominator to which individuals react. Future studies will have to address this issue. The interpretation of the observed responses as stress-reactions is tentative as no specific psychological measures of stress were used. However, as reactions to novelty commonly are described as stress–responses in literature,[10, 11, 50] we consider interpreting the findings as “stress–response”

as appropriate. A selection bias cannot be ruled out as study participants were solely recruited from individuals planning a stay at the health resort. However, spa therapy being covered by health insurance in Austria, selection based on income or

education is unlikely. In conclusion, this study shows that a travel-related temporary change of residence (CoR) leads to a mild stress response in humans as documented by an increase in BP and a disruption of sleep. BP responded already on LBH589 mw the day before CoR, indicating the effect of travel anticipation. Individual differences did not affect the response to any large extent. The findings have several implications. First, humans are sensitive to staying overnight in a novel environment. Second, individuals looking for restoration Cell press should consider several day stays as the restorative potential of a single day may be dampened by the novelty response. Third, tourist providers possibly could decrease the novelty response by providing experientially accessible information so tourists can get a “feeling” for their destination beforehand. Fourth, vacation studies and studies on resort-based spa therapy should not rely on measures taken on the days immediately preceding or following the onset of the stay, as these measures could be distorted by

the documented novelty response. The authors state that they have no conflicts of interest. “
“Objective. To evaluate whether changes in attack rates of fecal-orally transmitted diseases among travelers are related to changes in pretravel vaccination practices or better hygienic standards at travel destination. Methods. National surveillance data on all laboratory-confirmed cases of travel-related hepatitis A, shigellosis, and typhoid fever diagnosed in the Netherlands from 1995 to 2006 were matched with the number of Dutch travelers to developing countries to calculate region-specific annual attack rates. Trends in attack rates of non-vaccine-preventable shigellosis were compared with those of vaccine-preventable hepatitis A and typhoid fever. Trends were also compared with three markers for hygienic standards of the local population at travel destinations, drawn from the United Nations Development Programme database: the human development index, the sanitation index, and the water source index.

From month 4 to year 3, 63 (66%) of the patients with the Δ32

deletion and 264 (52%) of the patients without the deletion had a stable virological response (P=0.02). When the follow-up period was extended (month 4 to year 5), 44 patients (48%) and 168 patients (35%), respectively, were found to have a stable virological response (P=0.01). At year 5, differences were also noted between Δ32/wt and wt/wt patients when patients were categorized according to cART experience: in the cART-naïve subgroup, 51 and 45% of patients, respectively, had a stable response, and in the cART-pretreated subgroup, 46 and 27% of patients, respectively, had a stable response (this difference was significant; PMantel Haentzel=0.02). The percentage of patients with CD4 counts >500 cells/μL did not differ significantly between the Δ32 and wild-type patients; at year 3, 55 and 49% of patients, respectively, had CD4 counts >500 cells/μL Vemurafenib (P=0.26), and at year 5 these percentages were 52 and Maraviroc manufacturer 54%, respectively (P=0.73). After adjustment for confounding factors, the Δ32 deletion was significantly associated with a sustained virological response during the period from 4 months to 5 years post-enrolment

(P=0.04), and was nearly significantly associated with a sustained virological response during the period from 4 months to 3 years post-enrolment (P=0.07) (Table 2). In terms of the immunological response, the Δ32 deletion was not significantly associated with a CD4 count >500 cells/μL at year 3 (P=0.78) or at year 5 (P=0.15). Among 609 HIV-1-infected patients started on a PI-containing regimen, the frequency of patients heterozygous for CCR5 Δ32 was 16%: frequencies were 4% for patients born in Africa and 19% for patients born in Europe, similar to findings of previous studies carried Calpain out in similar populations [12,14,16,17]. The CCR5 Δ32 deletion was associated with a better virological response

to cART up to 3 and 5 years. A better virological response did not translate into a significantly better immunological response at any time during the study. At baseline, patients with the Δ32 deletion were older, had higher CD4 cell counts and had lower HIV RNA measurements than patients without the deletion. This might be explained by the effect of the CCR5 Δ32 deletion on the natural evolution of HIV infection before these patients started cART. Indeed, previous studies have shown that the presence of an allele with CCR5 Δ32 confers delayed progression to HIV-1 disease in the absence of cART [3,4]. Furthermore, the effect of the deletion may have contributed to a possible selection bias [19]. Indeed, the patients who could be included in the genetic bank study were those who had survived from 1997 to 2002, they were younger. This bias limits the interpretation of our results, as only those patients with a better prognosis were included in the study.

The 5240 bp genomic DNA fragment of clone P11-6B was sequenced and analyzed. The complete nucleotide sequence was determined, and a blast homology search revealed several ORFs (Fig. 1a). Among these, there were three entire ORFs coding, respectively, for a BglG, a BglF, and a BglB protein (Fig. 1b). Putative ribonucleic antiterminator sequences (RAT-like sequences 1 and 2) were also found, upstream from the selleck chemicals bglG and bglF genes. Sequence analysis showed that these genes were organized like the bgl operon

of E. coli (Schnetz et al., 1987; Schnetz & Rak, 1988). The first whole ORF, including 831 nucleotides, was found to encode a 277 amino acids member of the BglG family. The BglG protein is a transcriptional antiterminator. A putative ribonucleic antiterminator sequence (RAT-like sequence 1) was identified 51 bp upstream from the ATG. PTS regulatory domains (PRD1 and PRD2) were also found (Fig. 1b). These domains are conserved in the similar proteins from different species of bacteria (Schnetz et al., 1987; check details An et al., 2004). The second ORF, consisting of 1851 nucleotides, was found to encode a 617 amino acids member of the BglF family. The BglF protein is a β-glucoside-specific IIABC subunit of the PTS system. A putative ribonucleic antiterminator sequence (RAT-like sequence 2) was found 95 bp upstream from

the ATG, and a putative ribosome-binding site (RBS), AGGA, was identified 8 bp upstream Mirabegron from the start of the bglF ORF (Fig. 1b). Two typical domains, EIIB and EIIA, are conserved in BglF proteins. These domains contain two amino acids, a cysteine (position 26) and a histidine (position 538), identified as putative phosphorylation sites

(Saier, 1989). The end of the bglG ORF and the start of the bglF ORF are separated by 136 nucleotides. The third ORF, spanning 1392 nucleotides, was found to encode a protein 464 amino acids member of the BglB family. BglB is a β-glucosidase, a typical member of glycoside hydrolase family 1. Only 12 nucleotides separate the bglF and bglB ORFs. In this part of the sequence, a putative RBS, AGGAG, is present seven bases upstream from the start of the bglB ORF (Fig. 1b). Sequence analyses with the blastx program revealed a high degree of identity to the corresponding sequences of Enterobacter sp. 638, Pectobacterium carotovarum ssp. carotovarum (An et al., 2004), and E. coli K12 (Schnetz et al., 1987) (Table 2). Our blast analysis in GenBank of its deduced amino acid sequence indicates that it shares 94% homology with a deduced Enterobacter sp. 638 sequence that has never been studied functionally or characterized. The bglG and bglF ORFs identified on the insert also share high homology with Enterobacter sp. 638 ORFs. Our β-glucosidase may thus be an Enterobacter enzyme, in keeping with the fact that five of our 11 purified clones belong to this genus and display β-glucosidase activity.
