TL;DR: FoxO proteins play essential roles in the response to physiologic oxidative stress and thereby mediate quiescence and enhanced survival in the HSC compartment, a function that is required for its long-term regenerative potential.

TL;DR: The role of the mammalian FoxO transcription factor family (FoxO1, FoxO3, and FoxO4) in PI3K-AKT signaling appears to be an obligate event in the development of cancer.

TL;DR: LKB1 is established as a critical barrier to pulmonary tumorigenesis, controlling initiation, differentiation and metastasis in lung cancer, and expression profiling in human lung cancer cell lines and mouse lung tumours identified a variety of metastasis-promoting genes as targets of LKB1 repression.

TL;DR: It is shown that Foxo3a–/– female mice exhibit a distinctive ovarian phenotype of global follicular activation leading to oocyte death, early depletion of functional ovarian follicles, and secondary infertility, raising the possibility that accelerated follicular initiation plays a role in premature ovarian failure, a common cause of infertility and premature aging in women.

TL;DR: The generation and characterization of a p16Ink4a-specific knockout mouse that retains normal p19Arf function are described, establishing that p 16Ink 4a, along with p19 Arf, functions as a tumour suppressor in mice.
