1. Caracterização funcional da interação entre as proteínas CTSP-1 e CTCF / Functional characterization of the interaction between the proteins CTSP-1 and CTCF.
Cancer-testis (CT) antigens are immunogenic proteins expressed in gametogenic tissues and in different histological types of tumors, being considered promising candidates for cancer immunotherapy. However, little is known about their role in tumorigenesis. In 2006, we identified CTSP-1 as a novel CT antigen, frequently expressed in different types of tumors.

2. Estudos bioquímicos, funcionais e estruturais da septina humana SEPT2: fatores que determinam a formação de agregados / Functional and structural studies of human SEPT2: determinant factors triggering the sefl-assembly into amyloid fibrils
As septinas fazem parte de uma família de proteínas de ligação ao nucleotídeo guanina. As septinas têm mostrado ter um papel importante na citocinese e outros processos celulares, incluindo a determinação da polaridade celular e reorganização do citoesqueleto. Todos os membros da família de septinas são compostos por três domínios: um N-termina

3. Analysis of the stress-inducible transcription factor SsNAC23 in sugarcane plants
Stresses such as cold and drought can impair plant yield and induce a highly complex array of responses. Sugarcane (Saccharum spp.) is cultivated in tropical and subtropical areas and is considered a cold-sensitive plant. We previously showed that cold stress induces the expression of several genes in in vitro sugarcane plantlets. Here we characterize one of

4. 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.

5. Neurospora crassa mat A-2 and mat A-3 proteins weakly interact in the yeast two-hybrid system and affect yeast growth
Mating-type genes control the entry into the sexual cycle, mating identity and sexual development in fungi. The mat A-2 and mat A-3 genes, present in the mat A idiomorph of the filamentous fungus Neurospora crassa, are required for post-fertilization functions but are not essential for mating identity. Their putative roles as transcription factors are based

6. Estudos estruturais e funcionais da proteina stanniocalcina-1 humana, um novo marcador de microambiente de leucemia / Structural and functional studies of human protein stanniocalcina-1, a new microenvironmental marker of leukemia
Staniocalcins (STCs) represent a small family of glycoprotein hormones found in all vertebrates composed by STC1 and STC2, which have been initially implicated in calcium homeostasis and also recently implicated in several other processes. Stanniocalcin-1 (STC1), the first member found, was originally discovered in bony fishes and later identified in humans

7. Estudos das interações da septina 4 humana / Study of Human Septin 4 interactions
Septinas são proteínas ligantes a GTP encontradas desde fungos até metazoários. A primeira função identificada para septinas foi o seu papel central na organização e dinâmica do septo de divisão de leveduras. Uma das características marcantes é que septinas se organizam em heterofilamentos de 7 a 9 nm de espessura que foram purificados de diverso

8. Genes diferencialmente expressos em Paracoccidioides brasiliensis
Paracoccidioides brasiliensis is a thermally dimorphic fungus causing paracoccidioidomycosis, an endemic disease widespread in Latin America. The dimorphic transition from the mycelia (22 C) to the yeast (36 C) form is induced by a shift from the environmental temperature to that of the mammalian host. Genes that are differentially expressed in phases of P.

9. Identificação e estudo funcional de genes associados com doenças neurológicas / Identification an functional estudy of genes associated with neurological diseases
In this work we have used different approaches to the study of genes associated with CNS development and function as well as with neurological diseases: 1) one study involved the identification of the allele associated with an X-linked recessive sindromic form of mental retardation, Snyder-Robinson syndrome, in a Brazilian family. Using genetic linkage analy

10. Estudos funcionais e estruturais da proteina humana hnRNP Q/NSAP1 / Funcional and structural studies of human protein hnRNPQ
The members of the hnRNPs family (heterogenous nuclear ribonuclein proteins) play important roles in gene expression control and mRNAs metabolism. The proteins hnRNPD (AUF1) and hnRNPQ (NSAP1) were the main targets of this study. AUF1 has two RNA recognition motifs (RRM) and participates in the process of destabilization of a class of mRNAs that contain AU-r

11. Obtaining a fluorescent and resistant hybrid yeast to the nystatin / Obtenção de levedura híbrida fluorescente e resistente a nistatina
Vats contamination by wild yeasts can harm the efficiency and the productivity of ethanol industrial production and there are not efficient methods to control this type of contamination. Easiness, speed and the low cost would be desirable characteristics for the control of yeasts that eventually contaminate the fermentation process. With this aim, TAVARES (1

12. Identificação de interações proteína-proteína entre NS5 do vírus da febre amarela e proteínas celulares.
Yellow fever is an infectious disease caused by the yellow fever virus (YFV), a Flavivirus transmitted to humans by Aedes aegypti mosquitoes. Despite the existence of the yellow fever vaccine, the disease is endemic in South America and Africa, causing public health problems such as dispersed outbreaks, epidemics with variable impact and the risk of re-emerg
