Arrest defective 1 (ARD1) is an acetyltransferase that is highly conserved across organisms, from yeasts to humans. The high homology and widespread expression of ARD1 across multiple species and tissues signify that it serves a fundamental role in cells. Human ARD1 (hARD1) has been suggested to be involved in diverse biological processes, and its role in(More)
Overexpression of Notch1 has been associated with breast cancer. We recently showed that visfatin stimulates breast cancer cell proliferation and invasion. The present study was undertaken to determine whether Notch1 signaling is affected by visfatin and to characterize the functional role of the visfatin-Notch1 axis in breast cancer. Visfatin and Notch1(More)
Ninjurin1 is a transmembrane protein involved in macrophage migration and adhesion during inflammation. It was recently reported that repression of Ninjurin1 attenuated the lipopolysaccharide (LPS)-induced inflammatory response in macrophages; however, the precise mechanism by which Ninjurin1 modulates LPS-induced inflammation remains poorly understood. In(More)
The RUNX family represents a small group of heterodimeric transcription factors that master-regulate osteogenesis and hematopoiesis in mammals. Their genetic defects cause human diseases such as cleidocranial dysplasia (CCD) and acute myelogenous leukemia. However, the mechanism(s) regulating their functions are still poorly understood. Here, we report a(More)
The Runt domain transcription factor, PEBP2/CBF, is a heterodimer composed of 2 subunits. The DNA-binding alpha subunit, or RUNX protein, interacts with a partner PEBP2beta/CBFbeta through the evolutionarily conserved Runt domain. Each of the genes encoding RUNX1 and PEBP2beta/CBFbeta is frequently involved in acute myeloid leukemia. The chimeric protein,(More)
AIMS Our aims were to determine the role of Notch1 in mediating visfatin-induced angiogenesis and to explore potential target genes involved. METHODS AND RESULTS Inhibition of Notch signalling attenuated visfatin-induced angiogenesis in vitro, ex vivo, and in vivo. Visfatin increased γ-secretase activity, Notch1 cleavage and activation, and Hes1 gene(More)
Notch1 has been reported to be highly expressed in triple-negative and other subtypes of breast cancer. Mutant p53 (R280K) is overexpressed in MDA-MB-231 triple-negative human breast cancer cells. The present study aimed to determine whether the mutant p53 can be a potent transcriptional activator of the Notch1 in MDA-MB-231 cells, and explore the role of(More)
The repair process after CNS injury shows a well-organized cascade of three distinct stages: inflammation, new tissue formation, and remodeling. In the new tissue formation stage, various cells migrate and form the fibrotic scar surrounding the lesion site. The fibrotic scar is known as an obstacle for axonal regeneration in the remodeling stage. However,(More)
Trichostatin A (TSA), histone deacetylase inhibitor, shows a promising therapeutic effect on cancer cells in combination with radiotherapy or chemotherapy. However, little has been reported on the combined treatment of TSA with hyperthermia. Here, we have assessed the effect of TSA/hyperthermia on human glioblastoma A172 cells and found that TSA increases(More)
Over the last few decades, molecular neurobiology has uncovered many genes whose deficiency in mice results in behavioral traits associated with human neuropsychiatric disorders such as autism, obsessive-compulsive disorder (OCD), and schizophrenia. However, the etiology of these common diseases remains enigmatic with the potential involvement of a battery(More)
