摘要: Model organisms have emerged as suitable and reliable biological tools to study the properties of proteins whose function is altered in human disease. In case PI3K PTEN cancer-related proteins, several vertebrate invertebrate models, including mouse, fly, worm amoeba, been exploited obtain relevant functional information that has conserved from these humans along evolution. The yeast Saccharomyces cerevisiae an eukaryotic unicellular organism lacks a canonical mammalian-like PI3K/PTEN pathway PIP3 physiological second messenger, PIP2 being essential for its life. mammalian can be reconstituted S. cerevisiae, generating growth alteration phenotypes easily monitored perform vivo analysis molecular constituents this pathway. Here, we review current nonmammalian model systems function, summarize our knowledge orthologs species propose sensitive sensor oncogenicity tumor suppressor activity.
