Resumo: Abstract Nowadays, it is necessary to search for different high-scale production strategies to produce recombinant proteins of economic interest. Only a few microorganisms are industrially relevant for recombinant protein production: methylotrophic yeasts are known to use methanol efficiently as the sole carbon and energy source. Pichia pastoris is a methylotrophic yeast characterized as being an economical, fast and effective system for heterologous protein expression. Many factors can affect both the product and the production, including the promoter, carbon source, pH, production volume, temperature, and many others; but to control all of them most of the time is difficult and this depends on the initial selection of each variable. Therefore, this review focuses on the selection of the best promoter in the recombination process, considering different inductors, and the temperature as a culture medium variable in methylotrophic Pichia pastoris yeast. The goal is to understand the effects associated with different factors that influence its cell metabolism and to reach the construction of an expression system that fulfills the requirements of the yeast, presenting an optimal growth and development in batch, fed-batch or continuous cultures, and at the same time improve its yield in heterologous protein production.

Título: Hipermetilación del gen supresor de tumores p53 en pacientes pediátricos con leucemia linfoblástica aguda / Hypermethylation of tumor suppressor gene p53 in Chilean pediatrics patients under 15 years with acute lymphoblastic leukemia

Resumo: La leucemia linfoblástica aguda (LLA) es la neoplasia maligna hematooncólogica más frecuente en pacientes pediátricos contando hasta 75% de las leucemias y 32-35% del total de cánceres infantiles. Aunque la LLA es considerada una enfermedad con base genética, es cada vez más evidente que alteraciones epigenéticas desempeñan un rol central en su patogénia y progresión. La hipermetilación de regiones promotoras de genes es asociada con la pérdida de función génica. El gen supresor de tumores p53 (GST), es uno de los principales genes en el ciclo celular y apoptosis. El objetivo de este trabajo fue determinar el estado de metilación en la región del promotor-exón 1 del GST p53 y la asociación con la supervivencia en menores de 15 años con LLA. Se analizaron 40 pacientes provenientes de la Región de la Araucanía-Chile. La hipermetilación del p53 se determinó combinando enzimas de restricción sensibles a metilación (HpaII y EcoR II) y reacción en cadena de la polimerasa. Los resultados indicaron que 15/40 casos (37,5%) presentaron hipermetilación. Se encontró una diferencia estadística en la supervivencia según estado de metilación de p53 en el grupo de niñas (p=0,02). Considerando el total de pacientes, una tendencia a mejor supervivencia cuando los recuentos de leucocitos fueron <30.000/mm3 (p=0,08). Se encontró frecuentemente hipermetilado el gen p53 en la región del promotor-exon1. Esto indicaría que la hipermetilación del GST p53 puede ser un evento importante en la patogénesis de la LLA.

Acute lymphoblastic leukemia (ALL) is the most common hematology oncology malignancy in pediatric patients counting up to 75% of leukemias and 32­35% of all childhood cancers. Although ALL is considered a disease with a genetic basis, it is increasingly clear that epigenetic alterations play a central role in the pathogenesis and work was to determine the methylation status in promoter-exon1 of the TSG-p53 and association with survival in children under 15 years with ALL. In our study 40 patients from the Araucanía Region, Chile were analyzed. Hypermethylation of p53 was determined by combining restriction enzymes sensitive to methylation (HpaII and EcoR II) and polymerase chain reaction. Results indicated that 15/40 cases (37.5%) showed hypermethylation. Statistical difference was found in survival according to p53 methylation status in the girls group (p=0.02). Considering all patients, there was a trend to improved survival when leukocyte counts were <30.000/ul (p=0.08). We found the p53 gene frequently hypermethylated in the promoter-exon1 region. This would indicate that TSG p53 hypermethylation may be an important event in the pathogenesis of ALL.

Título: Development of a novel vector for cloning and expressing extremely toxic genes in Escherichia coli

Resumo: Background: Escherichia coli has been widely used as a host to clone and express heterologous genes. However, there are few vectors available for cloning and expressing extremely toxic genes, which limits further basic and applied research on extremely toxic proteins. Results: In this study, a novel vector pAU10 was constructed in E. coli. pAU10 utilizes the combination of the efficient but highly repressible T7-lacO promoter/operator and the strong rrnBT2 transcriptional terminator upstream of the T7 promoter to strictly control unwanted transcription of the extremely toxic gene; in addition, the trp promoter/operator is oriented opposite to the T7 promoter to control the production of the antisense RNA that may block the translation of leaky mRNA. Without the supplementation of IPTG and L-tryptophan in the culture medium, transcription of the extremely toxic gene by the T7 promoter is highly repressed, and the trp promoter produces the antisense RNA, which strictly prevents unwanted expression of the extremely toxic protein in E. coli. With the supplementation of IPTG and L-tryptophan, the T7 promoter efficiently transcribes the extremely toxic gene, and the trp promoter does not produce the antisense RNA, ensuring efficient expression of the extremely toxic protein in E. coli. Tight regulation and efficiency of expression of an extremely toxic gene cloned in the vector pAU10 were confirmed by cloning and expressing the restriction endonuclease-encoding gene bamHI without its corresponding methylase gene in E. coli JM109(DE3). Conclusion: pAU10 is a good vector used for cloning and expressing extremely toxic genes in E. coli.

Título: Putative 3-nitrotyrosine detoxifying genes identified in the yeast Debaryomyces hansenii: in silico search of regulatory sequences responsive to salt and nitrogen stress
Fonte: Electron. j. biotechnol;29:1-6, sept. 2017. graf, tab.
Idioma: en.
Projeto: DGAPA-UNAM.
Resumo: Background: During salt stress, the yeast Debaryomyces hansenii synthesizes tyrosine as a strategy to avoid the oxidation of proteins. Tyrosine reacts with nitrogen radicals to form 3-nitrotyrosine. 3-nitrotyrosine prevents the effects of associated oxidative stress and thus contributes to the high halotolerace of the yeast. However, the mechanism of how D. hansenii counteracts the presence of this toxic compound is unclear. In this work, we evaluated D. hansenii's capacity to assimilate 3-nitrotyrosine as a unique nitrogen source and measured its denitrase activity under salt stress. To identify putative genes related to the assimilation of 3-nitrotyrosine, we performed an in silico search in the promoter regions of D. hansenii genome. Results: We identified 15 genes whose promoters had binding site sequences for transcriptional factors of sodium, nitrogen, and oxidative stress with oxidoreductase and monooxygenase GO annotations. Two of these genes, DEHA2E24178g and DEHA2C00286g, coding for putative denitrases and having GATA sequences, were evaluated by RT-PCR and showed high expression under salt and nitrogen stress. Conclusions: D. hansenii can grow in the presence of 3-nitrotyrosine as the only nitrogen source and has a high specific denitrase activity to degrade 3-nitrotyrosine in 1 and 2 M NaCl stress conditions. The results suggest that given the lack of information on transcriptional factors in D. hansenii, the genes identified in our in silico analysis may help explain 3-nitrotyrosine assimilation mechanisms.

Resumo: Background: Streptomyces clavuligerus was the producer of clavulanic acid, claR, a pathway-specific transcriptional regulator in S. clavuligerus, positively regulates clavulanic acid biosynthesis. In this study, the promoter-less kanamycin resistance gene neo was fused with claR to obtain strain NEO from S. clavuligerus F613-1. The claR-neo fusion strain NEO was mutated using physical and chemical mutagens and then screened under high concentrations of kanamycin for high-yield producers of clavulanic acid. Results: The reporter gene neo was fused downstream of claR and used as an indicator for expression levels of claR in strain NEO. After three rounds of continuous treatment and screening, the high-yield clavulanic acid-producing strain M3-19 was obtained. In the shaking flask model, the clavulanic acid titer of M3-19 reached 4.33 g/L, which is an increase of 33% over the titer of 3.26 g/L for the starting strains S. clavuligerus F613-1 and NEO. Conclusions: Our results indicate that neo can be effectively used as a reporter for the expression of late-stage biosynthetic genes when screening for high-yield strains and that this approach has strong potential for improving Streptomyces strains of industrial value.

Título: High interleukin-4 expression and interleukin-4 gene polymorphisms are associated with susceptibility to human paracoccidioidomycosis
Fonte: Mem. Inst. Oswaldo Cruz;110(6):781-785, Sept. 2015. tab, graf.
Idioma: en.
Resumo: Paracoccidioidomycosis (PCM) is caused by dimorphic fungi from theParacoccidioides brasiliensis complex. Previous studies have demonstrated that the severity of disease is associated with a T-helper 2 immune response characterised by high interleukin (IL)-4 production. In the present study we analysed two polymorphisms in the IL-4gene (-590 C/T and intron-3 microsatellite) in 76 patients with PCM and 73 control subjects from an endemic area. The production of IL-4 by peripheral blood mononuclear cells after antigen or phytohaemagglutinin stimulation was determined by ELISA. A significant correlation was observed between the RP2/RP2 intron-3 genotype and infection with Paracoccidioides sp.(p = 0.011), whereas the RP1/RP1 genotype was correlated with resistance. No significant correlation was observed for the IL-4promoter polymorphism. Furthermore, the low IL-4 expression observed in the control group compared with patients was associated with the RP1/RP1 genotype. These results suggest that IL-4polymorphisms might be associated with the ability of the host to control Paracoccidioides sp.infection. The relevance of this polymorphism is supported by the observation that patients with disease produce high levels of IL-4 following mitogen or antigen stimulation. The IL-4gene is located in the cytokine cluster region of chromosome 5 where other polymorphisms have also been described.

Título: Small activating RNA induces myogenic differentiation of rat adipose-derived stem cells by upregulating MyoD
Fonte: Int. braz. j. urol;41(4):764-772, July-Aug. 2015. graf.
Idioma: en.
Projeto: National Natural Science Foundation of PR China.
Resumo: ABSTRACTPurpose:RNA activation (RNAa) is a mechanism of gene activation triggered by promoter-targeted small double stranded RNAs (dsRNAs), also known as small activating RNAs (saRNAs). Myogenic regulatory factor MyoD is regarded as the master activator of myogenic differentiation cascade by binding to enhancer of muscle specific genes. Stress urinary incontinence (SUI) is a condition primarily resulted from urethral sphincter deficiency. It is thus expected that by promoting differentiation of adipose-derived stem cells (ADSCs) into myoblasts by activating MyoD gene through RNAa may offer benefits to SUI.Materials and Methods:Rats ADSCs were isolated, proliferated in vitro, and identified by flow cytometry. Purified ADSCs were then transfected with a MyoD saRNA or control transfected. Real-time polymerase chain reaction (RT-PCR) and western blotting were used to detect MyoD mRNA and protein expression, respectively. Immunocytochemical staining was applied to determine the expression of desmin protein in transfected cells. Cell viability was measured by using CellTiter 96® AQueous One Solution Cell Proliferation Assay kit.Results:Transfection of a MyoD saRNA (dsMyoD) into ADSCs significantly induced the expression of MyoD at both the mRNA and protein levels, and inhibited cell proliferation. Desmin protein expression was detected in dsMyoD treated ADSCs 2 weeks later.Conclusion:Our findings show that RNAa mediated overexpression of MyoD can promote transdifferentiation of ADSCs into myoblasts and may help treat stress urinary incontinence (SUI)–a condition primarily resulted from urethral sphincter deficiency.

Resumo: BackgroundThe hepatitis C virus has been recognized as the leading cause of chronic liver disease in the world. Host genetic factors have been implicated in the persistence of hepatitis C virus infection. Single nucleotide polymorphisms at positions -607 C/A (rs1946518) and -137 G/C (rs187238) in the IL-18 gene promoter have been suggested to be associated with delayed hepatitis C virus clearance and persistence of the disease.ObjectiveIdentify these polymorphisms in a population infected with hepatitis C virus from the Brazilian Amazon region.MethodsIn a cross-sectional analytical study conducted in Belém, Pará, Brazil, 304 patients infected with hepatitis C virus were divided into two groups: group A, patients with persistent infection; group B, patients with spontaneous clearance. The control group consisted of 376 volunteers not infected with hepatitis C virus. Samples were analyzed by RT-PCR for the detection of viral RNA and by RFLP-PCR to evaluate the presence of the -137 G/C and -607 C/A IL-18 gene promoter polymorphisms.ResultsComparison of polymorphism allele frequencies between the patient and control groups showed a higher frequency of allele C at position -607 among patients (P=0.02). When the association between the polymorphisms and viral infection was analyzed, patients carrying genotype C/A at position -607 were found to be at higher risk of persistent hepatitis C virus infection (P=0.03).ConclusionThe present results suggest a possible role of the -607 IL-18 gene promoter polymorphism in the pathogenesis of hepatitis C virus infection.

ContextoO vírus da hepatite C é reconhecido como a maior causa de doença hepática crônica no mundo. Fatores genéticos do hospedeiro têm sido implicados na persistência da infecção pelo vírus da hepatite C. Polimorfismos de nucleotídeos únicos na posição -607 C/A (rs1946518) e -137 G/C (rs187238) na região promotora do gene da IL-18 têm sido evidenciados em alguns estudos que sugerem sua associação ao atraso na depuração do vírus da hepatite C e na persistência da doença.ObjetivoO presente estudo pretende identificar esses polimorfismos em uma população da região da Amazônia Brasileira infectada pelo vírus da hepatite C.MétodosEstudo do tipo transversal analítico no município de Belém-PA foi realizado em 304 pacientes infectados pelo vírus da hepatite C, divididos em: grupo A, pacientes com infecção persistente; grupo B, pacientes que apresentaram clareamento viral. Como grupo controle participaram 376 voluntários não infectados pelo vírus da hepatite C. As amostras foram submetidas à RT-PCR, para detecção do RNA viral e, posteriormente, à RFLP-PCR para avaliação do polimorfismo na região promotora do gene da IL-18, nas posições -137 G/C e -607 C/A.ResultadosA comparação das frequências dos polimorfismos no grupo de pacientes com o grupo controle demonstrou uma maior frequência do alelo C na posição -607 entre os pacientes (P=0,02) que no grupo controle. Na análise da associação dos polimorfismos com a infecção viral foi obtido que portadores do genótipo C/A na posição -607 possuíam maior risco de infecção persistente pelo vírus da hepatite C (P=0,03).ConclusãoNossos resultados sugerem uma possível implicação do polimorfismo da região promotora -607 do gene IL-18 na patogenia da infecção pelo vírus da hepatite C.

Knowing their status offers the possibility to establish strategies to help with professional development and training. Objectives. 1) To describe the characteristics of pediatric intensive care residency programs across Argentina. 2) To assess whether certain characteristics are related to a higher vacancy filling rate. 3) To assess job placement in the hospital where residents are trained. Design. Descriptive, observational study. National survey. Inclusion criteria. Pediatric intensive care residency programs in place between April 1st, 2014 and May 31st, 2014. Results. Thirty-one residency programs were analyzed. Only 11/31 had an annual hospitalization volume >400patients. There were no guidelines and/or criteria for care in 9/31. The program suited the national reference frameworkin17/31. There was no head ofresidents or resident trainer in 13/31. Only 5/31 had been certified by the Ministry of Health. There were 65 vacancies; this number increased in the past four years; vacancy filling rate decreased from 59% in 2009 to 30% in 2013. Sixty percent of residents got a job in the pediatric intensive care unit where they were trained. A multivariate logistic regression analysis identified the outcome measure annual hospitalization volume >400 patients as an independent predictor of vacancy filling rate >60%. Conclusions. 1) Vacancy filling is deficient. 2) The number of certified residency programs is scarce. 3) Pediatric intensive care units with a higher number of hospitalizations were associated with a higher vacancy filling rate. 4) More than half of residents got a job in the pediatric intensive care unit where they were trained.
