The Bcl-2 protein family plays a central role in mitochondrial membrane permeabilization. This event and the ensuing release of cytochrome c are decisive in the apoptotic cascade. Therefore, a better knowledge of these processes and their regulation will probably lead to the development of novel therapeutic strategies for treatment of apoptosis-related(More)
During cerebral inflammation uracil nucleotides leak to the extracellular medium and activate glial pyrimidine receptors contributing to the development of a reactive phenotype. Chronically activated microglia acquire an anti-inflammatory phenotype that favors neuronal differentiation, but the impact of these microglia on astrogliosis is unknown. We(More)
As a model organism Saccharomyces cerevisiae has greatly contributed to our understanding of many fundamental aspects of cellular biology in higher eukaryotes. More recently, engineered yeast models developed to study endogenous or heterologous proteins that lay at the root of a given disease have become powerful tools for unraveling the molecular basis of(More)
Multilocus sequence typing (MLST) represents the gold standard genotyping method in studies concerning microbial population structure, being particularly helpful in the detection of clonal relatedness. However, its applicability on large-scale genotyping is limited due to the high cost and time spent on the task. The selection of the most informative(More)
Restoration of the p53 pathway, namely by reactivation of mutant (mut) p53, represents a valuable anticancer strategy. Herein, we report the identification of the enantiopure tryptophanol-derived oxazoloisoindolinone SLMP53-1 as a novel reactivator of wild-type (wt) and mut p53, using a yeast-based screening strategy. SLMP53-1 has a p53-dependent(More)
An increasing number of researchers are using the Saccharomyces cerevisiae chronological aging model to gain insight into the post-mitotic cellular aging. Recently, an alternative approach to the traditional cellular viability assay by colony-forming unit (CFU) counts, based on the propidium iodide (PI) staining combined with flow cytometry (PI-FCM), was(More)
In the last years there was an increase in the use of several organisms such as plants and yeast for medical and biotechnological purposes. Both organisms are very useful when research in humans is nonpossible or unfeasible due to ethical issues. There are several advantages of using model organisms such as the availability of genomic information, the(More)
