1. Identification of the molecular mechanisms associated with acute type A aortic dissection through bioinformatics methods
Aortic dissection is characterized by the redirection of blood flow, which flows through an intimal tear into the aortic media. The purpose of this study was to find potential acute type A aortic dissection (AAAD)-related genes and molecular mechanisms by bioinformatics. The gene expression profiles of GSE52093 were obtained from Gene Expression Omnibus (GEO

2. Perspectivas para triagem Genética da intolerância à lactose: rastreamento do polimorfismo -13910 C/T, no gene MCM6, em neonatos
Lactose intolerance has been, for many years, considered as a worldwide problem in many children and adults. Objective: The aim is to investigate the prevalence of polymorphism -13910C/T, in a neonatal tracking, for early diagnosis of lactose tolerance/intolerance. Material and Methods: A cross-sectional case study of 310 Brazilian newborns. DNA was extracte

3. A new member of the MCM protein family encoded by the human MCM8 gene, located contrapodal to GCD10 at chromosome band 20p12.3–13
The MCM8 protein from HeLa cells, a new member of the MCM family, co-isolates through several steps with MCM6 and MCM7, and MCM8 co-immunoprecipitates with MCM4, MCM6 and MCM7, proteins reportedly forming a helicase complex involved in initiation of DNA replication. MCM8 mRNA is expressed in placenta, lung and liver, but is also significantly expressed in ad

4. Identification and functional characterization of a new member of the human Mcm protein family: hMcm8
The six minichromosome maintenance proteins (Mcm2–7) are required for both the initiation and elongation of chromosomal DNA, ensuring that DNA replication takes place once, and only once, during the S phase. Here we report on the cloning of a new human Mcm gene (hMcm8) and on characterisation of its protein product. The hMcm8 gene contains the central Mcm

5. Tup1p represses Mcm1p transcriptional activation and chromatin remodeling of an a-cell-specific gene
In yeast, a number of regulatory proteins expressed only in specific cell types interact with general transcription factors in a combinatorial manner to control expression of cell-type-specific genes. We report a detailed analysis of activation and repression events that occur at the promoter of the a-cell-specific STE6 gene fused to a β-galactosidase gene

6. Drosophila Minichromosome Maintenance 6 Is Required for Chorion Gene Amplification and Genomic Replication
Duplication of the eukaryotic genome initiates from multiple origins of DNA replication whose activity is coordinated with the cell cycle. We have been studying the origins of DNA replication that control amplification of eggshell (chorion) genes during Drosophila oogenesis. Mutation of genes required for amplification results in a thin eggshell phenotype, a

7. In vivo interactions of archaeal Cdc6/Orc1 and minichromosome maintenance proteins with the replication origin
Although genome analyses have suggested parallels between archaeal and eukaryotic replication systems, little is known about the DNA replication mechanism in Archaea. By two-dimensional gel electrophoreses we positioned a replication origin (oriC) within 1 kb in the chromosomal DNA of Pyrococcus abyssi, an anaerobic hyperthermophile, and demonstrated t

8. Base modification pattern at the wobble position of Xenopus selenocysteine tRNA(Sec).
We examined the base modification pattern of Xenopus tRNA(Sec) using microinjection into Xenopus oocytes, with particular focus on the wobble base U34 at the first position of the anticodon. We found that U34 becomes modified to mcm5U34 (5-methylcarboxymethyluridine) in the oocyte cytoplasm in a rather complex manner. When the tRNA(Sec) gene is injected into

9. In vitro studies of the binding of the ARGR proteins to the ARG5,6 promoter.
ARGRI, ARGRII, and ARGRIII regulatory proteins control the expression of arginine anabolic and catabolic genes in Saccharomyces cerevisiae. We show here that they are also required in vitro to observe a protein-DNA complex with the promoter of the ARG5,6 gene. The specific binding of ARGR proteins in vitro is stimulated by arginine. Antibodies raised against

10. The E2 Ubiquitin Conjugase Rad6 Is Required for the ArgR/Mcm1 Repression of ARG1 Transcription
Transcription of the Saccharomyces cerevisiae ARG1 gene is under the control of both positive and negative elements. Activation of the gene in minimal medium is induced by Gcn4. Repression occurs in the presence of arginine and requires the ArgR/Mcm1 complex that binds to two upstream arginine control (ARC) elements. With the recent finding that the E2 ubiqu

11. Role of alpha2 protein in donor locus selection during mating type interconversion.
The homeodomain protein alpha2p plays a role both in transcriptional repression in the process of cell type determination and in donor selection during mating interconversion. We have explored the mechanism of alpha2p-directed donor selection by examining the effects on donor preference of mutants deficient in alpha2p-mediated transcriptional repression. As

12. Amino termini of histones H3 and H4 are required for a1-alpha2 repression in yeast.
The Saccharomyces cerevisiae alpha2 repressor controls two classes of cell-type-specific genes in yeast through association with different partners. alpha2-Mcm1 complexes repress a cell-specific gene expression in haploid alpha cells and diploid a/alpha cells, while a1-alpha2 complexes repress haploid-specific genes in diploid cells. In both cases, repressio
