Abstract
Analysis of bone marrow aspirates (BMAs) is an essential step in the diagnosis of hematological disorders. This analysis is usually performed based on a visual examination of samples under a conventional optical microscope, which involves a labor-intensive process, limited by clinical experience and subject to high observer variability. In this work, we present a comprehensive digital microscopy system that enables BMA analysis for cell type counting and differentiation in an efficient and objective manner. This system not only provides an accessible and simple method to digitize, store, and analyze BMA samples remotely but is also supported by an Artificial Intelligence (AI) pipeline that accelerates the differential cell counting process and reduces interobserver variability. It has been designed to integrate AI algorithms with the daily clinical routine and can be used in any regular hospital workflow.

Abstract
PURPOSE Hip fracture is a public health problem worldwide. Traditional prognostic models do not include blood biomarkers, such as those obtained by proteomics. This study aimed to investigate the relationships between serum inflammatory biomarkers and frailty in older adults with hip fracture as well as adverse outcomes at one and three months after discharge. METHODS A total of 45 patients aged 75 or older who were admitted for hip fracture were recruited. At admission, a Comprehensive Geriatric Assessment (CGA) was conducted, which included a frailty assessment using the Clinical Frailty Scale (CFS). Blood samples were collected before surgery. Participants were followed up at one and three months after discharge. The levels of 45 cytokines were analyzed using a high-throughput proteomic approach. Binary logistic regression was used to determine independent associations with outcomes, such as functional recovery, polypharmacy, hospital readmission, and mortality. RESULTS The results showed that IL-7 (OR 0.66 95% CI 0.46-0.94, p = 0.022) and CXCL-12 (OR 0.97 95% CI 0.95-0.99, p = 0.011) were associated with better functional recovery at three months after discharge, while CXCL-8 (OR 1.07 95% CI 1.01-1.14, p = 0.019) was associated with an increased risk of readmission. CONCLUSIONS These findings suggest that immunology biomarkers may represent useful predictors of clinical outcomes in hip fracture patients.

Abstract
PURPOSE The gut microbiota plays important roles in health and disease. We questioned whether the gut microbiota and related metabolites are altered in monoclonal gammopathies and evaluated their potential role in multiple myeloma and its response to treatment. EXPERIMENTAL DESIGN We used 16S rRNA sequencing to characterize and compare the gut microbiota of patients with monoclonal gammopathy of undetermined significance (n = 11), smoldering multiple myeloma (n = 9), newly diagnosed multiple myeloma (n = 11), relapsed/refractory multiple myeloma (n = 6), or with complete remission (n = 9). Short-chain fatty acids (SCFA) were quantified in serum and tested in cell lines. Relevant metabolites were validated in a second cohort of 62 patients. RESULTS Significant differences in alpha- and beta diversity were present across the groups and both were lower in patients with relapse/refractory disease and higher in patients with complete remission after treatment. Differences were found in the abundance of several microbiota taxa across disease progression and in response to treatment. Bacteria involved in SCFA production, including Prevotella, Blautia, Weissella, and Agathobacter, were more represented in the premalignant or complete remission samples, and patients with higher levels of Agathobacter showed better overall survival. Serum levels of butyrate and propionate decreased across disease progression and butyrate was positively associated with a better response. Both metabolites had antiproliferative effects in multiple myeloma cell lines. CONCLUSIONS We demonstrate that SCFAs metabolites and the gut microbiota associated with their production might have beneficial effects in disease evolution and response to treatment, underscoring its therapeutic potential and value as a predictor.

Abstract
Subsets of multiple myeloma (MM) and monoclonal gammopathies of undetermined significance (MGUS) present with a monoclonal immunoglobulin specific for hepatitis C virus (HCV), thus are presumably HCV-driven, and antiviral treatment can lead to the disappearance of antigen stimulation and improved control of clonal plasma cells. Here we studied the role of hepatitis B virus (HBV) in the pathogenesis of MGUS and MM in 45 HBV-infected patients with monoclonal gammopathy. We analyzed the specificity of recognition of the monoclonal immunoglobulin of these patients and validated the efficacy of antiviral treatment (AVT). For 18 of 45 (40%) HBV-infected patients, the target of the monoclonal immunoglobulin was identified: the most frequent target was HBV (n=11), followed by other infectious pathogens (n=6) and glucosylsphingosine (n=1). Two patients whose monoclonal immunoglobulin targeted HBV (HBx and HBcAg), implying that their gammopathy was HBV-driven, received AVT and the gammopathy did not progress. AVT efficacy was then investigated in a large cohort of HBV-infected MM patients (n=1367) who received or did not receive anti-HBV treatments and compared to a cohort of HCV-infected MM patients (n=1220). AVT significantly improved patient probability of overall survival (P=0.016 for the HBV-positive cohort, P=0.005 for the HCV-positive cohort). Altogether, MGUS and MM disease can be HBV- or HCV-driven in infected patients, and the study demonstrates the importance of AVT in such patients.

Abstract
INTRODUCTION Hip fractures are the most common fracture leading to hospitalization and are associated with high costs, mortality rates and functional decline. Although several guidelines exist for preventing new fractures and promoting functional recovery, they tend to focus on osteoporosis treatment and do not take into account the complexity of frailty in older adults and geriatric syndromes, which are important factors in individuals at risk of suffering from frailty fractures. Moreover, most health systems are fragmented and are incapable of providing appropriate management for frail and vulnerable individuals who are at risk of experiencing fragility fractures. Multicomponent interventions and physical exercise using tele-rehabilitation could play a role in the management of hip fracture recovery. However, the effectiveness of exercise prescription and its combination with a comprehensive geriatric assessment (CGA) is still unclear. METHODS This randomized clinical trial will be conducted at the Hospital Universitario de Navarra (Pamplona, Spain). A total of 174 older adults who have suffered a hip fracture and fulfil the criteria for inclusion will be randomly allocated to either the intervention group or the control group. The intervention group will receive a multicomponent intervention consisting of individualized home-based exercise using the @ctive hip app for three months, followed by nine months of exercise using Vivifrail. Additionally, the intervention group will receive nutrition intervention, osteoporosis treatment, polypharmacy adjustment and evaluation of patient mood, cognitive impairment and fear of falling. The control group will receive standard outpatient care according to local guidelines. This research aims to evaluate the impact of the intervention on primary outcome measures, which include changes in functional status during the study period based on the Short Physical Performance Battery. DISCUSSION The findings of this study will offer valuable insights into the efficacy of a comprehensive approach that considers the complexity of frailty in older adults and geriatric syndromes, which are important factors in individuals at risk of suffering from frailty fractures. This study's findings will contribute to the creation of more effective strategies tailored to the requirements of these at-risk groups.

Abstract
Osteoporosis is a skeletal disease that can increase the risk of fractures, leading to adverse health and socioeconomic consequences. However, current clinical methods have limitations in accurately estimating fracture risk, particularly in older adults. Thus, new technologies are necessary to improve the accuracy of fracture risk estimation. In this observational study, we aimed to explore the association between serum cytokines and hip fracture status in older adults, and their associations with fracture risk using the FRAX reference tool. We investigated the use of a proximity extension assay (PEA) with Olink. We compared the characteristics of the population, functional status and detailed body composition (determined using densitometry) between groups. We enrolled 40 participants, including 20 with hip fracture and 20 without fracture, and studied 46 cytokines in their serum. After conducting a score plot and two unpaired t-tests using the Benjamini-Hochberg method, we found that Interleukin 6 (IL-6), Lymphotoxin-alpha (LT-α), Fms-related tyrosine kinase 3 ligand (FLT3LG), Colony stimulating factor 1 (CSF1), and Chemokine (C-C motif) ligand 7 (CCL7) were significantly different between fracture and non-fracture patients (p < 0.05). IL-6 had a moderate correlation with FRAX (R2 = 0.409, p < 0.001), while CSF1 and CCL7 had weak correlations with FRAX. LT-α and FLT3LG exhibited a negative correlation with the risk of fracture. Our results suggest that targeted proteomic tools have the capability to identify differentially regulated proteins and may serve as potential markers for estimating fracture risk. However, longitudinal studies will be necessary to validate these results and determine the temporal patterns of changes in cytokine profiles.

Abstract
Despite the approval of several drugs for AML, cytarabine is still widely used as a therapeutic approach. However, 85% of patients show resistance and only 10% overcome the disease. Using RNA-seq and phosphoproteomics, we show that RNA splicing and serine-arginine-rich (SR) proteins phosphorylation were altered during cytarabine resistance. Moreover, phosphorylation of SR proteins at diagnosis were significantly lower in responder than non-responder patients, pointing to their utility to predict response. These changes correlated with altered transcriptomic profiles of SR protein target genes. Notably, splicing inhibitors were therapeutically effective in treating sensitive and resistant AML cells as monotherapy or combination with other approved drugs. H3B-8800 and venetoclax combination showed the best efficacy in vitro, demonstrating synergistic effects in patient samples and no toxicity in healthy hematopoietic progenitors. Our results establish that RNA splicing inhibition, alone or combined with venetoclax, could be useful for the treatment of newly diagnosed or relapsed/refractory AML.

Abstract
CRISPR is becoming an indispensable tool in biological research, revolutionizing diverse fields of medical research and biotechnology. In the last few years, several CRISPR-based genome-targeting tools have been translated for the study of hematological neoplasms. However, there is a lack of reviews focused on the wide uses of this technology in hematology. Therefore, in this review, we summarize the main CRISPR-based approaches of high throughput screenings applied to this field. Here we explain several libraries and algorithms for analysis of CRISPR screens used in hematology, accompanied by the most relevant databases. Moreover, we focus on (1) the identification of novel modulator genes of drug resistance and efficacy, which could anticipate relapses in patients and (2) new therapeutic targets and synthetic lethal interactions. We also discuss the approaches to uncover novel biomarkers of malignant transformations and immune evasion mechanisms. We explain the current literature in the most common lymphoid and myeloid neoplasms using this tool. Then, we conclude with future directions, highlighting the importance of further gene candidate validation and the integration and harmonization of the data from CRISPR screening approaches.

Abstract
Background Pancreatic ductal adenocarcinoma (PDAC) is characterized by dense desmoplastic stroma that limits the delivery of anticancer agents. VCN-01 is an oncolytic adenovirus designed to replicate in cancer cells with a dysfunctional RB1 pathway and express hyaluronidase. Here, we evaluated the mechanism of action of VCN-01 in preclinical models and in patients with pancreatic cancer. Methods VCN-01 replication and antitumor efficacy were evaluated alone and in combination with standard chemotherapy in immunodeficient and immunocompetent preclinical models using intravenous or intratumoral administration. Hyaluronidase activity was evaluated by histochemical staining and by measuring drug delivery into tumors. In a proof-of-concept clinical trial, VCN-01 was administered intratumorally to patients with PDAC at doses up to 1×1011 viral particles in combination with chemotherapy. Hyaluronidase expression was measured in serum by an ELISA and its activity within tumors by endoscopic ultrasound elastography. Results VCN-01 replicated in PDAC models and exerted antitumor effects which were improved when combined with chemotherapy. Hyaluronidase expression by VCN-01 degraded tumor stroma and facilitated delivery of a variety of therapeutic agents such as chemotherapy and therapeutic antibodies. Clinically, treatment was generally well-tolerated and resulted in disease stabilization of injected lesions. VCN-01 was detected in blood as secondary peaks and in post-treatment tumor biopsies, indicating virus replication. Patients had increasing levels of hyaluronidase in sera over time and decreased tumor stiffness, suggesting stromal disruption. Conclusions VCN-01 is an oncolytic adenovirus with direct antitumor effects and stromal disruption capabilities, representing a new therapeutic agent for cancers with dense stroma. Trial registration number EudraCT number: 2012-005556-42 and NCT02045589.

Abstract
Multiple myeloma (MM) remains an incurable plasma cell malignancy. While its origin is enigmatic, an association with infectious pathogens including hepatitis C virus (HCV) has been suggested. Here we report nine patients with monoclonal gammopathy of undetermined significance (MGUS) or MM with previous HCV infection, six of whom received antiviral treatment. We studied the evolution of the gammopathy disease, according to anti-HCV treatment and antigen specificity of purified monoclonal immunoglobulin, determined using the INNO-LIA™ HCV Score assay, dot-blot assays, and a multiplex infectious antigen microarray. The monoclonal immunoglobulin from 6/9 patients reacted against HCV. Four of these patients received antiviral treatment and had a better evolution than untreated patients. Following antiviral treatment, one patient with MM in third relapse achieved complete remission with minimal residual disease negativity. For two patients who did not receive antiviral treatment, disease progressed. For the two patients whose monoclonal immunoglobulin did not react against HCV, antiviral treatment was not effective for MGUS or MM disease. Our results suggest a causal relationship between HCV infection and MGUS and MM progression. When HCV was eliminated, chronic antigen-stimulation disappeared, allowing control of clonal plasma cells. This opens new possibilities of treatment for MGUS and myeloma.

Abstract
Service-Learning is an educational methodology that allows student learning while addressing community needs. A program in microbiology and infectious diseases was implemented in Universidad Complutense de Madrid, Spain. University lecturers, clinical microbiologists, doctorate students, and undergraduates from several Bachelor Degrees and courses worked in an interdisciplinary team along with social institutions that attend disadvantaged persons. Using commercial movies that deal with infectious diseases, the students learn clinical microbiology, prepare divulgation materials, visit social centers to accompany, and help others to know about illnesses and prevention. The program was developed through two academic years and involved 58 voluntary students, 13 teachers and tutors, and 4 social entities as community partners. Postsurvey evaluation of the program revealed a highly satisfactory achievement of goals: acquiring scientific and personal competencies by university students, including critical analysis and science diffusion, solving problems or collaborative team working, and contributing, together with the tutors, to the social responsibility of the university.

Abstract
Among the different mechanisms involved in oxidative stress, protein carbonylation and lipid peroxidation are both important modifications associated with the pathogenesis of several diseases, including cancer. Hematopoietic cells are particularly vulnerable to oxidative damage, as the excessive production of reactive oxygen species and associated lipid peroxidation suppress self-renewal and induce DNA damage and genomic instability, which can trigger malignancy. A richer understanding of the clinical effects of oxidative stress might improve the prognosis of these diseases and inform therapeutic strategies. The most common protein carbonylation and lipid peroxidation compounds, including hydroxynonenal, malondialdehyde, and advanced oxidation protein products, have been investigated for their potential effect on hematopoietic cells in several studies. In this review, we focus on the most important protein carbonylation and lipid peroxidation biomarkers in hematological malignancies, their role in disease development, and potential treatment implications.

Abstract
FMS-like tyrosine kinase 3 (FLT3) is a key driver of acute myeloid leukemia (AML). Several tyrosine kinase inhibitors (TKIs) targeting FLT3 have been evaluated clinically, but their effects are limited when used in monotherapy due to the emergence of drug-resistance. Thus, a better understanding of drug-resistance pathways could be a good strategy to explore and evaluate new combinational therapies for AML. Here, we used phosphoproteomics to identify differentially-phosphorylated proteins in patients with AML and TKI resistance. We then studied resistance mechanisms in vitro and evaluated the efficacy and safety of rational combinational therapy in vitro, ex vivo and in vivo in mice. Proteomic and immunohistochemical studies showed the sustained activation of ERK1/2 in bone marrow samples of patients with AML after developing resistance to FLT3 inhibitors, which was identified as a common resistance pathway. We examined the concomitant inhibition of MEK-ERK1/2 and FLT3 as a strategy to overcome drug-resistance, finding that the MEK inhibitor trametinib remained potent in TKI-resistant cells and exerted strong synergy when combined with the TKI midostaurin in cells with mutated and wild-type FLT3. Importantly, this combination was not toxic to CD34+ cells from healthy donors, but produced survival improvements in vivo when compared with single therapy groups. Thus, our data point to trametinib plus midostaurin as a potentially beneficial therapy in patients with AML.

Abstract
Control of oxidative stress in the bone marrow (BM) is key for maintaining the interplay between self-renewal, proliferation, and differentiation of hematopoietic cells. Breakdown of this regulation can lead to diseases characterized by BM failure such as the myelodysplastic syndromes (MDS). To better understand the role of oxidative stress in MDS development, we compared protein carbonylation as an indicator of oxidative stress in the BM of patients with MDS and control subjects, and also patients with MDS under treatment with the iron chelator deferasirox (DFX). As expected, differences in the pattern of protein carbonylation were observed in BM samples between MDS patients and controls, with an increase in protein carbonylation in the former. Strikingly, patients under DFX treatment had lower levels of protein carbonylation in BM with respect to untreated patients. Proteomic analysis identified four proteins with high carbonylation levels in MDS BM cells. Finally, as oxidative stress-related signaling pathways can modulate the cell cycle through p53, we analyzed the expression of the p53 target gene p21 in BM cells, finding that it was significantly upregulated in patients with MDS and was significantly downregulated after DFX treatment. Overall, our results suggest that the fine-tuning of oxidative stress levels in the BM of patients with MDS might control malignant progression.

Abstract
Exogenous cytokines are widely applied to enhance the anti-tumor ability of immune cells. However, systematic comparative studies of their effects on chimeric antigen receptor (CAR)-engineered T (CART) cells are lacking. In this study, CART cells targeting folate receptor-alpha were generated and expanded ex vivo in the presence of different cytokines (IL-2, IL-7, IL-15, IL-18, and IL-21), and their expansion, phenotype and cytotoxic capacity were evaluated, in vitro and in vivo. Moreover, the effect of the administration of these cytokines along with CART cells in vivo was also studied. IL-2, IL-7, and IL-15 favored the ex vivo expansion of CART cells compared to other cytokines or no cytokine treatment. IL-7 induced the highest proportion of memory stem cell-like CART cells in the final product, and IL-21 supported the expansion of CART cells with a younger phenotype, while IL-2 induced more differentiated CART cells. IL-2 and IL-15-exposed CART cells secreted more proinflammatory cytokines and presented stronger tumor-lysis ability in vitro. However, when tested in vivo, CART cells exposed to IL-2 ex vivo showed the least anti-tumor effect. In contrast, the administration of IL-15 and IL-21 in combination with CART cells in vivo increased their tumor killing capacity. According to our results, IL-7 and IL-15 show promise to promote ex vivo expansion of CART cells, while IL-15 and IL-21 seem better suited for in vivo administration after CART cell infusion. Collectively, these results may have a profound impact on the efficacy of CART cells in both hematologic and solid cancers.

Abstract
PURPOSE The main objective of this study is to describe the prevalence, degree and risk of corneal involvement, and visual impact in a pediatric population with blepharokeratoconjunctivitis (BKC). METHODS Retrospective, observational, case-control study. Clinical records of patients ≤16 years old with BKC seen between 2006 and 2012 were reviewed. The prevalence and relative risk of corneal involvement was evaluated between patients with and without corneal affection through a univariate and multivariate analysis with logistic regression. Visual acuity at presentation and at last follow-up visit was also analyzed. RESULTS One hundred and fourteen children with BKC, with a male-to-female ratio of 1 : 1 and a mean age at diagnosis of 9.13 years. The mean follow-up time was 26.4 (±25) months. Corneal involvement was present in 39.5% of patients, varying from superficial punctate keratitis to perforation. Corneal changes were not seen in children under 4 years old. The risk of corneal affection was greater in patients with photophobia, hordeolum, female gender and asymmetric disease (OR of 2.69, 11.6, 2.35 and 2.77, respectively). The mean best-corrected visual acuity at presentation was 0.20 (corneal affected group), compared to 0.11 (unaffected group; P=0.02). CONCLUSIONS Our study showed an older age at time of diagnosis and a worse visual outcome in patients with BKC and corneal disease compared with previous reports. Early diagnosis and detection of risk factors for corneal involvement, as well as adequate treatment, is mandatory to prevent serious long-term visual repercussions in children with BKC.

Abstract
Oncolytic adenoviruses can promote immune responses against tumors by expressing and/or displaying tumor-associated antigens. However, the strong immunodominance of viral antigens mask responses against tumor epitopes. In addition, defects in major histocompatibility complex class I antigen presentation pathway such as the downregulation of the transporter-associated with antigen processing (TAP) are frequently associated with immune evasion of tumor cells. To promote the immunogenicity of exogenous epitopes in the context of an oncolytic adenovirus, we have taken advantage of the ER localization of the viral protein E3-19K. We have inserted tumor-associated epitopes after the N-terminal signal sequence for membrane insertion of this protein and flanked them with linkers cleavable by the protease furin to facilitate their TAP-independent presentation. This strategy allowed an enhanced presentation of the exogenous epitopes in TAP-deficient tumor cells in vitro and the generation of higher specific immune responses in vivo that were able to significantly control tumor growth.

Abstract
PURPOSE Tumor targeting upon intravenous administration and subsequent intratumoral virus dissemination are key features to improve oncolytic adenovirus therapy. VCN-01 is a novel oncolytic adenovirus that combines selective replication conditional to pRB pathway deregulation, replacement of the heparan sulfate glycosaminoglycan putative-binding site KKTK of the fiber shaft with an integrin-binding motif RGDK for tumor targeting, and expression of hyaluronidase to degrade the extracellular matrix. In this study, we evaluate the safety and efficacy profile of this novel oncolytic adenovirus. EXPERIMENTAL DESIGN VCN-01 replication and potency were assessed in a panel of tumor cell lines. VCN-01 tumor-selective replication was evaluated in human fibroblasts and pancreatic islets. Preclinical toxicity, biodistribution, and efficacy studies were conducted in mice and Syrian hamsters. RESULTS Toxicity and biodistribution preclinical studies support the selectivity and safety of VCN-01. Antitumor activity after intravenous or intratumoral administration of the virus was observed in all tumor models tested, including melanoma and pancreatic adenocarcinoma, both in immunodeficient mice and immunocompetent hamsters. CONCLUSIONS Oncolytic adenovirus VCN-01 characterized by the expression of hyaluronidase and the RGD shaft retargeting ligand shows an efficacy-toxicity prolife in mice and hamsters by intravenous and intratumoral administration that warrants clinical testing.

Abstract
Streptomyces clavuligerus ATCC 27064 and S. clavuligerus ΔccaR::tsr cultures were grown in asparagine-starch medium, and samples were taken in the exponential and stationary growth phases. Transcriptomic analysis showed that the expression of 186 genes was altered in the ccaR-deleted mutant. These genes belong to the cephamycin C gene cluster, clavulanic acid gene cluster, clavams, holomycin, differentiation, carbon, nitrogen, amino acids or phosphate metabolism and energy production. All the clavulanic acid biosynthesis genes showed Mc values in the order of -4.23. The blip gene-encoding a β-lactamase inhibitory protein was also controlled by the cephamycin C-clavulanic acid cluster regulator (Mc -2.54). The expression of the cephamycin C biosynthesis genes was greatly reduced in the mutant (Mc values up to -7.1), while the genes involved in putative β-lactam resistance were less affected (Mc average -0.88). Genes for holomycin biosynthesis were upregulated. In addition, the lack of clavulanic acid and cephamycin production negatively affected the expression of genes for the clavulanic acid precursor arginine and of miscellaneous genes involved in nitrogen metabolism (amtB, glnB, glnA3, glnA2, glnA1). The transcriptomic results were validated by quantative reverse transcription polymerase chain reaction and luciferase assay of luxAB-coupled promoters. Transcriptomic analysis of the homologous genes of S. coelicolor validated the results obtained for S. clavuligerus primary metabolism genes.

Abstract
Adenovirus (Ad) i-leader protein is a small protein of unknown function. The C-terminus truncation of the i-leader protein increases Ad release from infected cells and cytotoxicity. In the current study, we use the i-leader truncation to enhance the potency of an oncolytic Ad. In vitro, an i-leader truncated oncolytic Ad is released faster to the supernatant of infected cells, generates larger plaques, and is more cytotoxic in both human and Syrian hamster cell lines. In mice bearing human tumor xenografts, the i-leader truncation enhances oncolytic efficacy. However, in a Syrian hamster pancreatic tumor model, which is immunocompetent and less permissive to human Ad, antitumor efficacy is only observed when the i-leader truncated oncolytic Ad, but not the non-truncated version, is combined with gemcitabine. This synergistic effect observed in the Syrian hamster model was not seen in vitro or in immunodeficient mice bearing the same pancreatic hamster tumors, suggesting a role of the immune system in this synergism. These results highlight the interest of the i-leader C-terminus truncation because it enhances the antitumor potency of an oncolytic Ad and provides synergistic effects with gemcitabine in the presence of an immune competent system.

Abstract
The oat2 gene, located in the clavulanic acid gene cluster in Streptomyces clavuligerus, is similar to argJ, which encodes N-acetylornithine:glutamic acid acetyltransferase activity. Purified proteins obtained by expression in Escherichia coli of the argJ and oat2 genes of S. clavuligerus posses N-acetyltransferase activity. The kinetics and substrate specificities of both proteins are very similar. Deletion of the oat2 gene did not affect the total N-acetylornithine transferase activity and slightly reduced the formation of clavulanic acid under standard culture conditions. However, the oat2 mutant produced more clavulanic acid than the parental strain in cultures supplemented with high levels (above 1 mM) of arginine. The purified S. clavuligerus ArgR protein bound the arginine box in the oat2 promoter, and the expression of oat2 was higher in mutants with a disruption in argR (arginine-deregulated), confirming that the Arg boxes of oat2 are functional in vivo. Our results suggest that the Oat2 protein or one of its reaction products has a regulatory role that modulates clavulanic acid biosynthesis in response to high arginine concentrations.

Abstract
Clavulanic acid is a secondary metabolite produced by Streptomyces clavuligerus. It possesses a clavam structure and a characteristic 3R,5R stereochemistry essential for action as a beta-lactamase inhibitory molecule. It is produced from glyceraldehyde-3-phosphate and arginine in an eight step biosynthetic pathway. The pathway is carried out by unusual enzymes, such as (1) the enzyme condensing both precursors, N2-(2-carboxyethyl)-arginine (CEA) synthetase, (2) the beta-lactam synthetase cyclizing CEA and (3) the clavaminate synthetase, a well-characterized multifunctional enzyme. Genes for biosynthesis of clavulanic acid and other clavams have been cloned and characterized. They offer new possibilities for modification of the pathway and for obtaining new molecules with a clavam structure. The state of the regulatory proteins controlling clavulanic acid biosynthesis, as well as the relationship between the biosynthetic pathway of clavulanic acid and other clavams, is discussed.

Abstract
A cluster of genes argCJBDRGH containing most of the arginine biosynthesis genes has been found in Streptomyces clavuligerus after sequencing a 8.3 kb DNA region containing overlapping sequences of two DNA fragments known to contain arginine biosynthesis genes. Subcloning, complementation of E. coli arginine auxotrophic strains and enzymatic assays confirmed the identity of each gene. S1 nuclease mapping studies and Northern hybridization analysis revealed the formation of two large transcripts corresponding to argCJBDR and argGH. The amount of each of these mRNAs is 10 to 44 times higher in a S. clavuligerus argR-disrupted mutant than in the wild type confirming the existence of an ArgR-mediated control of arginine biosynthesis gene expression. A low level constitutive monocistronic transcript of argR was observed in S. clavuligerus cells. Most of the argGH transcript initiating at an adenine 29 nt upstream of the argG initiation codon appears to stop at a termination stem and loop structure present downstream of the argG gene.

Abstract
The beta-lactamase inhibitor clavulanic acid is formed by condensation of a pyruvate-derived C3 unit with a molecule of arginine. A gene (pyc, for pyruvate converting) located upstream of the bls gene in the clavulanic acid gene cluster of Streptomyces clavuligerus encodes a 582-amino-acid protein with domains recognizing pyruvate and thiamine pyrophosphate that shows 29.9% identity to acetohydroxyacid synthases. Amplification of the pyc gene resulted in an earlier onset and higher production of clavulanic acid. Replacement of the pyc gene with the aph gene did not cause isoleucine-valine auxotrophy in the mutant. The pyc replacement mutant did not produce clavulanic acid in starch-asparagine (SA) or in Trypticase soy broth (TSB) complex medium, suggesting that the pyc gene product is involved in the conversion of pyruvate into the C3 unit of clavulanic acid. However, the beta-lactamase inhibitor was still formed at the same level as in the wild-type strain in defined medium containing D-glycerol, glutamic acid, and proline (GSPG medium) as confirmed by high-pressure liquid chromatography and paper chromatography. The production of clavulanic acid by the replacement mutant was dependent on addition of glycerol to the medium, and glycerol-free GSPG medium did not support clavulanic acid biosynthesis, suggesting that an alternative gene product catalyzes the incorporation of glycerol into clavulanic acid in the absence of the Pyc protein. The pyc replacement mutant overproduces cephamycin.

Abstract
beta-Lactam antibiotics are produced by prokaryotic and eukaryotic organisms. The genes for beta-lactam biosynthesis are organized in clusters but the location of the different genes is not identical. Biosynthesis genes are clustered with genes for resistance (bla, pbp) and for the efflux of the antibiotic (cmcT) in prokaryotes. Comparison of proteins reveals much larger differences for primary metabolism enzymes than for beta-lactam biosynthesis enzymes in producing organisms. This suggests a horizontal transfer of the beta-lactam antibiotic biosynthesis genes.

Abstract
Two genes, claR and car, encoding proteins involved in clavulanic acid biosynthesis, have been found in a 2.8-kb BglII-EcoRI DNA fragment of Streptomyces clavuligerus adjacent to the region containing the cephamycin and clavulanic acid biosynthesis gene cluster. claR encoded a protein of 431 amino acids (deduced Mr 47080), that showed a significant degree of homology with several transcriptional activators of the LysR family. The ClaR protein contained two helix-turn-helix (HTH) motifs in the amino and carboxyl terminal regions. The second gene, car, encoded a protein of 247 amino acids (Mr 26629) that showed a strong similarity to oxydoreductases of the SDR family. Twelve amino acids of the amino-terminal region were identical to those previously obtained by Edman degradation of the purified clavulanic-9-aldehyde reductase of S. clavuligerus. Amplification of the claR gene in multicopy plasmids resulted in a threefold increase in clavulanic acid production and in a five- to sixfold increase of alanylclavam biosynthesis, whereas cephamycin production was significantly reduced both in defined and in complex media. By contrast, amplification of the car gene had no significant effect on clavulanic acid and alanylclavam or cephamycin production. Both claR and car are expressed as monocistronic transcripts; the level of transcript declined rapidly after 48h in complex media, but low sustained levels of both transcripts were observed in defined GSPG medium until 96h. claR and car were not significantly expressed in mutants disrupted in the ccaR gene, a regulatory gene that controls positively clavulanic acid and cephamycin biosynthesis. These results indicate that clavulanic acid and cephamycin biosynthesis in S. clavuligerus is controlled by a cascade of regulatory proteins that include CcaR and ClaR.

Abstract
The argR gene of Streptomyces clavuligerus has been located in the upstream region of argG. It encodes a protein of 160 amino acids with a deduced M(r) of 17117 for the monomer. Transformants containing the amplified argR gene showed lower activity (50%) of the biosynthetic ornithine carbamoyltransferase (OTC) activity and higher levels (380%) of the catabolic ornithine aminotransferase (OAT) activity than control strains. Amplification of an arginine (ARG) box-containing sequence results in a 2- to 2.5-fold derepression of ornithine acetyltransferase and OTC, suggesting that the repressor is titrated out. Footprinting experiments using the pure homologous arginine repressor (AhrC) of B. subtilis showed a protected 38 nt region (ARG box) in the coding strand upstream of argC. The protected region contained two tandemly repeated imperfect palindromic 18-nt ARG boxes. The repressor-operator interaction was confirmed by bandshift experiments of the DNA fragment containing the protected region. By computer analysis of the Streptomyces sequences available in the databases, a consensus ARG box has been deduced for the genus Streptomyces. This is the first example of a clear regulation of an amino acid biosynthetic pathway in Streptomyces species, challenging the belief that actinomycetes do not have a well-developed regulatory system of these pathways.

Abstract
A regulatory gene (ccaR), located within the cephamycin gene cluster of Streptomyces clavuligerus, is linked to a gene (blp) encoding a protein similar to a beta-lactamase-inhibitory protein. Expression of ccaR is required for cephamycin and clavulanic acid biosynthesis in S. clavuligerus. The ccaR-encoded protein resembles the ActII-ORF4, RedD, AfsR, and DnrI regulatory proteins of other Streptomyces species, all of which share several motifs. Disruption of ccaR by targeted double recombination resulted in the loss of the ability to synthesize cephamycin and clavulanic acid. Complementation of the disrupted mutant with ccaR restored production of both secondary metabolites. ccaR was expressed as a monocistronic transcript at 24 and 48 h in S. clavuligerus cultures (preceding the phase of antibiotic accumulation), but no transcript hybridization signals were observed at 72 or 96 h. This expression pattern is consistent with those of regulatory proteins required for antibiotic biosynthesis. Amplification of ccaR in S. clavuligerus resulted in a two- to threefold increase in the production of cephamycin and clavulanic acid.

Abstract
The argG gene of Streptomyces clavuligerus (Scl) has been cloned by complementation of argG mutants of Escherichia coli and S. lividans (Sl). The argG nucleotide (nt) sequence showed that it corresponds to a new type of argG different from the corresponding genes of S. coelicolor (Sco) and Sl. It encodes a 43,250-Da protein that showed higher similarity to argininosuccinate synthetases (ASS) from Methanococcus vannielii and Methanosarcina barkeri than to ASS deduced from other Streptomyces argG. No hybridization of the Scl argG was found with the homologous genes of Sl or Sco. The argH gene was located downstream from argG in Scl. The genomic region around argG and argH in Scl was different from the homologous regions in other Streptomyces and is not genetically unstable, unlike in Sco and Sl. Amplification of argG in transformant Scl[pULAR113] results in a 2.3-fold increase in the production of clavulanic acid (CA) in relation to the control strain Scl[pIJ699].
