13. The zinc finger protein TcZFP2 binds target mRNAs enriched during Trypanosoma cruzi metacyclogenesis
Trypanosomes are parasitic protozoa in which gene expression is primarily controlled through the regulation of mRNA stability and translation. This post-transcriptional control is mediated by various families of RNA-binding proteins, including those with zinc finger CCCH motifs. CCCH zinc finger proteins have been shown to be essential to differentiation eve

14. Expression of phenazine biosynthetic genes during the arbuscular mycorrhizal symbiosis of Glomus intraradices
To explore the molecular mechanisms that prevail during the establishment of the arbuscular mycorrhiza symbiosis involving the genus Glomus, we transcriptionally analysed spores of Glomus intraradices BE3 during early hyphal growth. Among 458 transcripts initially identified as being expressed at presymbiotic stages, 20% of sequences had homology to previous

15. Occurrence of methicillin resistant Staphylococcus aureus (MRSA) among clinical samples in tehran-iran and its correlation with polymorphism of specific accessory gene regulator (AGR) groups
Methicillin-Resistant Staphylococcus aureus (MRSA) is responsible for an increasing number of serious hospital and community acquired infections. Virulence gene expression in Staphylococcus aureus is orchestrated by regulators such as the accessory gene regulator (agr). Staphylococcal strains are divided into four major agr groups (agrI-IV) on the basis of a

16. Expression of virulence genes by Listeria monocytogenes J0161 in natural environment
Majority of studies concerning the gene expression of Listeria monocytogenes have been done on pure culture states. Our objective was to study L.monocytogenes in a co-cultured state and to understand if microbes in their natural state of existence are different in their expression than that of the purely cultured lab grown forms. For a long period discussion

17. Mutações do gene cystic fibrosis transmembrane conductance regulator e deleções dos genes glutationa S-transferase em pacientes com fibrose cística no Brasil
OBJETIVO: Determinar os efeitos que a mutação do gene cystic fibrosis transmembrane conductance regulator (CFTR) e da deleção dos genes glutationa S-transferase (GST) mu-1 (GSTM1) e teta-1 (GSTT1) têm na evolução clínica da fibrose cística (FC) em pacientes da região sudeste do Brasil. MÉTODOS: Entre março de 2002 e março de 2005, incluímos no

18. Análise de genes modificadores relacionados à gravidade clínica da fibrose cística / Analysis of modifier genes related to the clinical severity in cystic fibrosis
Introduction: Cystic fibrosis (CF) is clinically manifested in various forms of gravity, modulated by different genotypes and environment. While the classes of mutations in the CFTR (Cystic Fibrosis Transmembrane Conductance Regulator) gene are well defined as modulators of severity in CF, polymorphisms remain controversial. Objective: To determine whether p

19. Influência do regulador CovR na resposta de Streptococcus mutans ao contato com saliva e sangue / Influence of the CovR regulator in Streptococcus mutans response to contact with saliva and blood
Streptococcus mutans é o principal patógeno da cárie dental em humanos, por ser capaz de se acumular no biofilme dentário principalmente na presença de sacarose e produzir e tolerar grandes concentrações de ácidos, os quais causam a desmineralização dos dentes. Além disto, S. mutans pode estar associado à etiologia da endocardite bacteriana, doen

20. Comparative analysis of two component signal transduction systems of the Lactobacillus acidophilus group
The Lactobacillus acidophilus group is a phylogenetically distinct group of closely related lactobacilli. Members of this group are considered to have probiotic properties and occupy different environmental niches. Bacteria generally sense and respond to environmental changes through two component systems (TCSs) which consist of a histidine protein kinase (H

21. Identification of coffee WRKY transcription factor genes and expression in resistance responses to pathogens.
In plants, WRKY proteins are a group of transcription factors existing as a gene superfamily that play important roles in regulation of defense response pathways. To assess the diversity of this protein family in coffee (Coffea spp.), data mining methods were used on a set of around 200,000 coffee expressed sequence tags. A total of 53 different putative WRK

23. Análises moleculares das vias de sinalização de morte celular originadas no retículo endoplasmático / Molecular analyses of cell death pathways signalling originated in the endoplasmic reticulum
Abiotic and biotic stresses are responsible for major losses in agricultural productivity world wise. Therefore, the understanding of mechanisms of plant stress response and adaptation to such conditions should provide the foundation for engineering plant stress tolerance and hence maximizing the yield of crops growing under adverse environmental conditions.

24. Expressão diferencial de genes em células foliculares de suínos
O objetivo neste trabalho foi identificar genes candidatos relacionados à ovulação em suínos. Para tanto, investigou-se a expressão diferencial dos genes STAR (steroidogenic acute regulator), GATA (GATA-binding protein 4), PGF2α (prostaglandin F2α), P4R (progesterone receptor), FSHR (follicle-stimulating hormone receptor) e CYP19 (cytochrome P450 arom
