1. ESTRATÉGIAS PARA CONSERVAÇÃO DE ACESSOS DE COQUEIRO ANÃO DO BAG DA EMBRAPA TABULEIROS COSTEIROS. / CONSERVATION STRATEGIES FOR COCONUT DWARF ACCESSIONS OF EMBRAPA COASTAL TABLELANDS BAG.
A conservação do coqueiro tem sido alvo de estudos nos últimos anos por organizações de pesquisa pública e privada. Essas pesquisas têm se concentrado na obtenção de protocolos por crescimento lento ou criopreservação. O armazenamento, como meio de manutenção da viabilidade do pólen, é importante para a preservação da variabilidade genética

4. "Um biossusceptômetro supercondutor AC para quantificar o ferro hepático". / A Superconductor AC Susceptometer to Quantify Liver Iron.
This work consisted in the development of a system to measure the magnetization of large paramagnetic and diamagnetic samples. The main application was susceptometric measurements of the hepatic tissue for quantification of the iron overload. Iron excess is commonly observed in thalassemic and sickle cell anemia patients who have repeatedly received red bloo

5. Bag1 Functions In Vivo as a Negative Regulator of Hsp70 Chaperone Activity
Studies on the Hsp70 chaperone machine in eukaryotes have shown that Hsp70 and Hsp40/Hdj1 family proteins are sufficient to prevent protein misfolding and aggregation and to promote refolding of denatured polypeptides. Additional protein cofactors include Hip and Bag1, identified in protein interaction assays, which bind to and modulate Hsp70 chaperone activ

6. Polypyrimidine tract binding protein and poly r(C) binding protein 1 interact with the BAG-1 IRES and stimulate its activity in vitro and in vivo
The 5′-untranslated region of Bag-1 mRNA contains an internal ribosome entry segment (IRES) and the translation of Bag-1 protein can be initiated by both cap-dependent and cap-independent mechanisms. In general, cellular IRESs require non-canonical trans-acting factors for their activity, however, very few of the proteins that act on cellular IRESs have be

7. Bag-1 Internal Ribosome Entry Segment Activity Is Promoted by Structural Changes Mediated by Poly(rC) Binding Protein 1 and Recruitment of Polypyrimidine Tract Binding Protein 1
We have shown previously that an internal ribosome entry segment (IRES) directs the synthesis of the p36 isoform of Bag-1 and that polypyrimidine tract binding protein 1 (PTB-1) and poly(rC) binding protein 1 (PCBP1) stimulate IRES-mediated translation initiation in vitro and in vivo. Here, a secondary structural model of the Bag-1 IRES has been derived by u

8. A recombinant retrovirus encoding alkaline phosphatase confirms clonal boundary assignment in lineage analysis of murine retina.
Recombinant retroviruses encoding the histochemically detectable enzyme beta-galactosidase have been used to investigate lineage in the vertebrate nervous system. Identification of the descendants of individual progenitors is straightforward when progeny cells are arranged in a reproducible, clustered pattern, but difficulties in interpretation arise when pr

9. Plasticity of the neoplastic phenotype in vivo is regulated by epigenetic factors
Age of host and transplantation-site microenvironment influence the tumorigenic potential of neoplastically transformed liver epithelial cells. Tumorigenic BAG2-GN6TF rat liver epithelial cells consistently form tumors at ectopic sites, but differentially express tumorigenicity or hepatocytic differentiation in the liver depending on host age and route of ce

10. Co-chaperones Bag-1, Hop and Hsp40 regulate Hsc70 and Hsp90 interactions with wild-type or mutant p53
Using highly purified proteins, we have identified intermediate reactions that lead to the assembly of molecular chaperone complexes with wild-type or mutant p53R175H protein. Hsp90 possesses higher affinity for wild-type p53 than for the conformational mutant p53R175H. The presence of Hsp90 in a complex with wild-type p53 inhibits the binding of Hsp40 and H

11. Chaperone action in the posttranslational topological reorientation of the hepatitis B virus large envelope protein: Implications for translocational regulation
The large L envelope protein of the hepatitis B virus utilizes a new folding pathway to acquire a dual transmembrane topology in the endoplasmic reticulum (ER). The process involves cotranslational membrane integration and subsequent posttranslational translocation of its preS subdomain into the ER. Here, we demonstrate that the conformational and functional

12. A role for endothelial cell lipoxygenase in the oxidative modification of low density lipoprotein.
Oxidative modification of low density lipoprotein (LDL) has been implicated as a factor in the generation of macrophage-derived foam cells in vitro and in vivo. However, the exact mechanism of LDL oxidation has not been established. The present studies show that cellular lipoxygenase activity is involved in endothelial cell-induced oxidation of LDL. Inhibito
