The activation of stress protein kinases is essential for proper cellular adaptation to external stimuli. In the yeast Saccharomyces cerevisiae, an increase of extra cellular osmolarity activates the MAP kinase pathway of Hog1, which is derived from a...
Cytotoxic T lymphocytes (CTLs) eliminate virus-infected tumor cells or alloantigen through a lyric mechanism, which involves the secretion of a cytoplasmic granules containing cytotoxic proteins, perforin and granzymes, of which the two most important are...
A team of researchers from the Autonomous University of Barcelona published a study showing that transposons can silence genes adjacent to or significantly reduce its expression by induction of synthesis of an antisense RNA. This new mechanism is now...
In the Faculty of Medicine of the University of Valladolid, the group of eicosanoids studied the role of iPLA2 (phospholipase A2 calcioindependiente) in group VI in the process of incorporation and release of arachidonic acid from phospholipids and,...
BMPs (bone morphogenetic proteins) are determining factors in the mechanisms of embryonic development and differentiation of tissues such as bone, muscle and nervous. It knows its restrictive action on neuronal differentiation, promoting the maintenance...
