Runx3/Pebp2alphaC null mouse gastric mucosa exhibits hyperplasias due to stimulated proliferation and suppressed apoptosis in epithelial cells, and the cells are resistant to growth-inhibitory and apoptosis-inducing action of TGF-beta, indicating that Runx3 is a major growth regulator of gastric epithelial cells. Between 45% and 60% of human gastric cancer(More)
Dorsal root ganglion (DRG) neurons specifically project axons to central and peripheral targets according to their sensory modality. The Runt-related genes Runx1 and Runx3 are expressed in DRG neuronal subpopulations, suggesting that they may regulate the trajectories of specific axons. Here we report that Runx3-deficient (Runx3(-/-)) mice displayed severe(More)
Histone deacetylase (HDAC) inhibitors are a relatively new class of anti-cancer agents that play important roles in epigenetic or non-epigenetic regulation, inducing death, apoptosis, and cell cycle arrest in cancer cells. Recently, their use has been clinically validated in cancer patients resulting in the approval of two HDAC inhibitors, vorinostat and(More)
T lymphocytes differentiate in discrete stages within the thymus. Immature thymocytes lacking CD4 and CD8 coreceptors differentiate into double-positive cells (CD4(+)CD8(+)), which are selected to become either CD4(+)CD8(-)helper cells or CD4(-)CD8(+) cytotoxic cells. A stage-specific transcriptional silencer regulates expression of CD4 in both immature and(More)
BACKGROUND While several molecular markers of bladder cancer prognosis have been identified, the limited value of current prognostic markers has created the need for new molecular indicators of bladder cancer outcomes. The aim of this study was to identify genetic signatures associated with disease prognosis in bladder cancer. RESULTS We used 272 primary(More)
Runt-related transcription factor 3 (Runx3) is essential for normal mouse development, and Runx3 knock-out (KO) mice (FVB strain), which die within 24 h after birth, show various organ defects, such as lung hyperplasia. For proper early liver development, angiogenesis and liver cell differentiation mechanisms are necessary in mammals. Previous studies have(More)
Dorsal root ganglion (DRG) neurons project their axons to specific target layers in the gray matter of the spinal cord, according to their sensory modality (Neuron 30 (2001), 707; Cell 101 (2000), 485; Neuron 31 (2001), 59; J. Comp. Neurol. 380 (1997), 215; Sensory Neurons, Oxford Univ. Press, New York, 1992, p. 131). Expression of runt-related Runx/AML(More)
Runx3, a Runt domain transcription factor, determines neurotrophin receptor phenotype in dorsal root ganglion (DRG) neurons. Molecular mechanisms by which Runx3 controls distinct neurotrophin receptors are largely unknown. Here, we show that RUNX3 abolished mRNA induction of TRKB expression, and concomitantly altered the neurotrophin response in a(More)
RUNX3 is a transcription factor that functions as a tumor suppressor. In some cancers, RUNX3 expression is down-regulated, usually due to promoter hypermethylation. Recently, it was found that RUNX3 can also be inactivated by the mislocalization of the protein in the cytoplasm. The molecular mechanisms controlling this mislocalization are poorly understood.(More)
