 en Morphological changes in the nucleus of the yeast Saccharomyces cerevisiae check for this species in other resources induced by the expression of gene pol of HIV-1
Sariol, Carlos; Falcon, Viviana & Morales-Grillo, Juan

Abstract

The present paper reports and discusses the effect of the expression of the gene pol of the human immunodeficiency virus (HIV) on the nucleus of the Saccharomyces cerevisiae check for this species in other resources yeast. This unexpected result is characterized by a loss of the nuclear membrane limits as well as of the characteristic homogeneity of the chromatin. This group of changes gives to the nucleus of the yeast a worm-eaten aspect after the induction of the expression of the pol gene. The possible relation of these changes with apoptosis and the possibility that S. cerevisiae may constitute a model for their study are discussed.

Resumen

En el presente trabajo se reporta y se discute el efecto de la expresión del gen pol del virus de la inmunodeficiencia humana (VIH) sobre el núcleo de la levadura Saccharomyces cerevisiae check for this species in other resources . Este resultado inesperado, se caracteriza por una pérdida de los límites de la membrana nuclear asi como de la homogeneidad característica de la cromatina. Estos cambios en su conjunto le confieren al núcleo de la levadura un aspecto carcomido luego de la inducción de la expresión del gen pol. La posible relación de estos cambios con la apoptosis y la posibilidad que S. cerevisiae pudiera constituir un modelo para el estudio de este fenómeno son discutidos.
