1. Identificação molecular, caracterização e análise de expressão de um gene inibidor de serina protease da lagarta Helicoverpa armigera (Lepidoptera: noctuidae) na cultura de algodão
Resumo Sabe-se que os inibidores de serina protease (serpinas), uma superfamília de inibidores de protease, estão envolvidos em vários processos fisiológicos, como desenvolvimento, metamorfose e imunidade inata. Neste estudo, um cDNA de serpina de comprimento total, denominado Haserpin1, foi isolado da lagarta Helicoverpa armigera na cultura de algodão.

2. Elevada frequência de Aeromonas spp. e genes de virulência em cultivos de tilápia-do-nilo (Oreochromis niloticus) em tanques-rede, na região semiárida de Pernambuco, Brasil
RESUMO Objetivou-se avaliar a ocorrência de Aeromonas spp. em peixes e amostras de água na região semiárida de Pernambuco e avaliar a frequência de aerolissina (aerA), enterotoxina citotóxica (act), enterotoxina citotônica (alt) e serina protease (ahp) nesses isolados. Foram analisados 70 peixes vivos e oito mortos com sinais clínicos de aeromoniose

3. [PROVISIONAL] Boundaries in metagenomic screenings using lacZα-based vectors
Article Metagenomics approaches have been of high relevance for providing enzymes used in diverse industrial applications. In the current study, we have focused on the prospection of protease and glycosyl hydrolase activities from a soil sample by using the lacZα -based plasmid pSEVA232. For this, we used a functional screen based on skimmed milk agar and a

4. Targeting of Virulence Factors and Plasmid Profiling of Klebsiella pneumoniae Causing Urinary Tract Infection in Sylhet City of Bangladesh
ABSTRACT Studies were conducted to characterize Klebsiella pneumoniae isolates from urinary tract infection (UTI) patients in Sylhet city of Bangladesh. At the same time, all isolates were screened for some common virulence genes and four significant isolates were searched for plasmid number and sizes by mini alkaline-lysis method. Among five tested isolates

5. Identification of potential target genes of USP22 via ChIP-seq and RNA-seq analysis in HeLa cells
Abstract The ubiquitin-specific protease 22 (USP22) is an oncogene and its expression is upregulated in many types of cancer. In the nucleus, USP22 functions as one subunit of the SAGA to regulate gene transcription. However, the genome-wide USP22 binding sites and its direct target genes are yet clear. In this study, we characterized the potential genomic b

6. The role of ClpX in erythropoietic protoporphyria
ABSTRACT Hemoglobin is an essential biological component of human physiology and its production in red blood cells relies upon proper biosynthesis of heme and globin protein. Disruption in the synthesis of these precursors accounts for a number of human blood disorders found in patients. Mutations in genes encoding heme biosynthesis enzymes are associated wi

7. Heterozygous HTRA1 missense mutation in CADASIL-like family disease
The aim of this study was to find related pathogenic genes in cerebral autosomal dominant arteriopathy with subcortical infarcts and leukoencephalopathy in (CADASIL)-like patients. The direct sequencing and high-throughput multiplex polymerase chain reaction (PCR) was performed to screen for related genes. The clinical and imaging data of a CADASIL-like pati

8. An overview of the molecular and epidemiological features of HIV-1 infection in two major cities of Bahia state, Brazil
BACKGROUND The high mutation rate of the human immunodeficiency virus (HIV) has created a public health challenge because the use of antiretroviral drugs can generate selective pressure that drives resistance in these viruses. OBJECTIVE The aim of this work was to characterise the molecular and epidemiological profile of HIV in Bahia, Brazil. METHODS D

9. Highly Solvent Tolerance in Serratia marcescens IBBPo15
ABSTRACT The aim of this study was to investigate the solvent tolerance mechanisms in Serratia marcescens strain IBBPo15 (KT315653). Serratia marcescens IBBPo15 exhibited remarkable solvent-tolerance, being able to survive in the presence of high concentrations (above 40%) of toxic organic solvents, such as cyclohexane, n-hexane, n-decane, toluene, styrene,

10. Filogenia molecular de Toxoplasmatinae: comparação entre inferências baseadas em sequências genéticas mitocondriais e de apicoplasto
Resumo A filogenia da subfamília Toxoplasmatinae tem sido amplamente investigada com diversos marcadores moleculares. Neste estudo, a filogenia molecular da subfamília Toxoplasmatinae foi analisada através de genes de apicoplasto e mitocondriais. Foram analisadas sequências parciais de genes de apicoplasto codificadores da protease caseinolítica (clpC),

11. Exploring plant growth-promotion actinomycetes from vermicompost and rhizosphere soil for yield enhancement in chickpea
Abstract The main objective of the present study was to isolate and characterize actinomycetes for their plant growth-promotion in chickpea. A total of 89 actinomycetes were screened for their antagonism against fungal pathogens of chickpea by dual culture and metabolite production assays. Four most promising actinomycetes were evaluated for their physiologi

12. Bioactive Cyanopeptides Produced by Sphaerocavum brasiliense Strains (Cyanobacteria)
The halogenated compounds aeruginosin and cyanopeptolin (protease inhibitors) are well documented in several cyanobacteria. In this work, the presence of genetic coding for aeruginosin and cyanopeptolin in Sphaerocavum genus and their characterization by mass spectrometry and potential toxic effects were investigated. Three strains of Sphaerocavum brasiliens
