Abstract:
:Primary mouse embryo fibroblasts passed in culture go through a period of declining growth rate and then after a period of minimal proliferation begin to grow again, generating, under appropriate conditions, an immortal 3T3 line. The 3T3 cells, but not the primary mouse embryo fibroblasts, are able to synthesize and to secrete mitogen regulated protein (MRP, also known as proliferin). We report here that the level at which the change in gene expression occurs during this spontaneous immortalization process is post-transcriptional, reflecting a change in either RNA processing or transcript stability. To our knowledge, this is the first report of an alteration at the post-transcriptional level of gene expression that accompanies immortalization.

杂志文章abstract::SIRT5 is one of the seven mammalian sirtuins which are NAD+-dependent deacylases. In human beings, SIRT5 gene encodes for four SIRT5 protein isoforms, namely SIRT5iso1, SIRT5iso2, SIRT5iso3, and SIRT5iso4. Previous studies have focused mostly on SIRT5iso1. Characteristics regarding localization, activity and tissue di...
