FoxOs in Tumor Suppression and Stem Cell Maintenance

The FoxO transcription factors have been implicated in many processes including tumor suppression and cell death. In this issue, two groups now report on mice that conditionally lack the three predominant FoxO transcription factors. Demonstrate that FoxOs are critical for the long-term maintenance of hematopoietic stem cells, and show that FoxOs suppress the formation of hemangiomas and lymphom...

FOXOs in the maintenance of vascular homoeostasis.

The mammalian FoxO (forkhead box O) transcription factors FoxO1, FoxO3 and FoxO4 represent one of several effector arms of the PI3K (phosphoinositide 3-kinase)-Akt signalling network that has been linked to cancer, metabolism and aging. Specific roles of the FoxOs in the vascular cell types have been investigated to reveal that they play redundant yet critical roles in the proliferation and sur...

Cell, Tumor, and Stem Cell Biology EZH2 Is Essential for Glioblastoma Cancer Stem Cell Maintenance

Overexpression of the polycomb group protein enhancer of zeste homologue 2 (EZH2) occurs in diverse malignancies, including prostate cancer, breast cancer, and glioblastoma multiforme (GBM). Based on its ability to modulate transcription of key genes implicated in cell cycle control, DNA repair, and cell differentiation, EZH2 is believed to play a crucial role in tissue-specific stem cell maint...

FOXOs and sirtuins in vascular growth, maintenance, and aging.

Blood vessels form the first organ in the developing embryo and build extensive networks that supply all cells with nutrients and oxygen throughout life. As blood vessels get older, they often become abnormal in structure and function, thereby contributing to numerous age-associated diseases including ischemic heart and brain disease, neurodegeneration, or cancer. First described as regulators ...

Down-regulation of HSP40 gene family following OCT4B1 suppression in human tumor cell lines

Objective(s): The OCT4B1, as one of OCT4 variants, is expressed in cancer cell lines and tissues more than other variants and plays an important role in apoptosis and stress (heat shock protein) pathways. The present study was designed to determine the effects of OCT4B1 silencing on expressional profile of HSP40 gene family expression in three different human tumor cell lines. Materials and Met...
