1. Jaburetox: update on a urease-derived peptide
Abstract Urease from Canavalia ensiformis seeds was the first enzyme ever to be crystallized, in 1926. These proteins, found in plants, bacteria and fungi, present different biological properties including catalytic hydrolysis of urea, and also enzyme-independent activities, such as induction of exocytosis, pro-inflammatory effects, neurotoxicity, antifungal

2. Desenvolvimento de vetores não virais para entrega gênica baseados na cadeia leve de dineína Rp3 = : Development of non viral vectors for gene delivery based on dynein light chain Rp3 / Development of non viral vectors for gene delivery based on dynein light chain Rp3
Gene delivery is a promising technique with great medical potential that consists in the introduction of exogenous nucleic acids, and can be applied for gene therapy as well as DNA vaccination. However, its use is still limited by the lack of an ideal delivery vector, which is both safe and efficient. Although much more effective, viral vectors still raise s

3. Retention of a recombinant GFP protein expressed by the yellow fever 17D virus in the E/NS1 intergenic region in the endoplasmic reticulum
The flaviviral envelope proteins, E protein and precursor membrane protein, are mainly associated with the endoplasmic reticulum (ER) through two transmembrane (TM) domains that are exposed to the luminal face of this compartment. Their retention is associated with the viral assembly process. ER-retrieval motifs were mapped at the carboxy terminus of these e

4. Effects of Epstein-Barr virus on the development of dendritic cells derived from cord blood monocytes: an essential role for apoptosis
OBJECTIVE: Epstein-Barr virus (EBV) is a ubiquitous human γ-herpes virus, which can adapt and evade host immune defense. Dendritic cells (DCs) play a pivotal role in the initiation and maintenance of immune responses. This study investigated the effects of EBV on cord blood monocytes derived DCs (CBDC). METHODS: Monocytes were isolated from cord blood and c

5. Papel de TGFβ-1 na regulação da expressão de MMPs seus inibidores (TIMPs e Reck) em modelo de carcinoma mamário humano: análise funcional de RECK e sua correlação com dados clínico-patológicos / Role of TGFβ-1 as a common regulator of MMPs and their inhibitors (TIMPs e RECK) in human breast cancer cell model: functional analysis of RECK and its correlation with clinical-pathological
The metastatic disease is the main mortality cause of breast cancer patients. The metastatic process involves a complex cascade of events, including the organized breakdown of the extracellular matrix (ECM) compounds. The degradation of ECM is tightly regulated by the balance between the activities of matrix metalloproteinases (MMPs) and their inhibitors, th

6. Construction of a recombinant adenovirus co-expressing truncated human prostate-specific membrane antigen and mouse 4-1BBL genes and its effect on dendritic cells
Our aim was to construct a recombinant adenovirus co-expressing truncated human prostate-specific membrane antigen (tPSMA) and mouse 4-1BBL genes and to determine its effect on dendritic cells (DCs) generated from bone marrow suspensions harvested from C57BL/6 mice for which the effect of 4-1BBL on DCs is not clear, especially during DCs processing tumor-ass

7. FGF2 species of 18 and 22.5 kDa: paracrine molecular signaling and biological functions / FGF2 de 18kDa e de 22,5kDa: sinalização molecular parácrina e funções biológias
FGF2 (Fibroblast Growth Factor 2), the founder of the FGF family, has regulatory functions in mitogenesis, differentiation, morphogenesis and tissue repair. Multiple FGF2 molecular species, sharing a C-terminal sequence of 155 amino acids, are translated from different iniciation sites of the same mRNA. The smaller, the FGF2-18kD, is extracellularly released

8. Kinetic study of Drosophila melanogaster cells transfected to produce the rabies vírus glycoprotein in bioreactor / Estudo cinético de células de Drosophila melanogaster transfectadas para a produção da glicoproteína da raiva em biorreator
The interest in using insect cells to produce complex proteins is due to its ease of cultivation and its glycosylation pattern equivalent to that of mammalian cells systems. The objective of this work was to identify the limiting or inhibiting factors for the production of a rabies virus glycoprotein (RVGP), expressed in the cytoplasmatic membrane of a trans

9. Estudo estrutural e funcional das proteínas PilZ e YaeQ do fitopatógeno Xanthomonas axonopodis pv citri / Structural and functional studies of PilZ and YaeQ from Xanthomonas axonopodis pv citri proteins
The aim of the project was to perform structural and functional studies of different Xanthomonas axonopodis pv citri (Xac) proteins including the hypothetical proteins YaeQ and SufE; RpfC, RpfF and RpfG involved in the quorum sensing and PilZ, FimX and PilB that play roles in type IV pilus (T4P) biogenesis. Several experimental techniques were employed inclu

10. Immune strategies using single-component LipL32 and multi-component recombinant LipL32-41-OmpL1 vaccines against leptospira
Genes encoding lipoproteins LipL32, LipL41 and the outer-membrane protein OmpL1 of leptospira were recombined and cloned into a pVAX1 plasmid. BALB/c mice were immunized with LipL32 and recombined LipL32-41-OmpL1 using DNA-DNA, DNA-protein and protein-protein strategies, respectively. Prime immunization was on day 1, boost immunizations were on day 11 and da

11. Expression, purification and characterization of surface proteins from Leptospira interrogans. / Expressão, purificação e caracterização de proteínas de superfície de Leptospira interrogans.
The whole-genome sequences of L. interrogans serovar Copenhageni and the bioinformatic tools allow us to choose fifteen genes encoding for conserved hypothetical proteins predicted to be exported to the membrane. The chosen genes were amplified by PCR from six predominant pathogenic serovars, the DNA cloned in an E. coli vector, the recombinant proteins expr

12. Action of recombinant Bauhinia inhibitors on prostate cancer cell line. / Ação de inibidores recombinantes de Bauhinia sobre a linhagem celular de câncer de próstata.
Prostate cancer occurs in Brazil with high rates of incidence and mortality. Invasion from the primary tumor and metastasis result in poorer prognosis. Diverse classes of protein play a role for the progression of metastasis. Tissue kallikreins, e.g., hK3 (PSA) and integrins are directly related to this neoplasia, as well as, in cell adhesion, differentiatio
