In the brain, aquaporin-1 (AQP-1), a water channel for high osmotic water permeability, is mainly expressed in the apical membrane of the ventricular choroid plexus and regulates formation of cerebrospinal fluid (CSF). Although the physiology of AQP-1 has been the subject of several publications, much less is known about the trans-acting factors involved in(More)
Thyroid transcription factor-1 (TTF-1) belongs to the Nkx family of homeodomain-containing proteins and regulates expression of several important genes in the brain. Our previous studies showed that TTF-1 plays an important role in water homeostasis in the subfornical organ of rats and is involved in cerebrospinal fluid formation by regulation of(More)
TTF-1 is a member of the NKx family of homeodomain genes, and is required for morphogenesis and fetal diencephalon development. Our previous studies have shown that TTF-1 expression is maintained in some regions of the postnatal rat brain and transactivates the gene expression of several neuropeptides. In this study, a potential role for TTF-1 in the(More)
OBJECT The aim of this study was to investigate changes in electroencephalography (EEG) patterns obtained from added or repositioned electrodes after those initially implanted had failed to indicate the true local ictal onset zone. The authors focused on the following matters: rationale for adding or repositioning electrodes, topographic and frequency(More)
OBJECTIVE α-Melanocyte-stimulating hormone (α-MSH) and agouti-related peptide (AgRP) control energy homeostasis by their opposing actions on melanocortin receptors (MC3/4R) in the hypothalamus. We previously reported that thyroid transcription factor-1 (TTF-1) controls feeding behavior in the hypothalamus. This study aims to identify the function of TTF-1(More)
BACKGROUND Inflammation plays a role in the response to metabolic stress in type 2 diabetes. However, the effects of rosiglitazone on inflammation of skeletal muscle have not been fully examined in type 2 diabetes. METHODS We investigated the effects of the insulin-sensitizing anti-diabetic agent, rosiglitazone, on the progression of skeletal muscle(More)
Thyroid transcription factor 1 (TTF-1) is required for morphogenesis of the fetal diencephalon. Previous reports showed that mice carrying a TTF-1 null mutation lacked normal development of the pituitary gland. In this study, a role for TTF-1 in the regulation of growth hormone and prolactin transcription was identified. In-situ hybridization analysis(More)
We have recently found that thyroid transcription factor-1 (TTF-1), a homeodomain-containing transcription factor, is postnatally expressed in discrete areas of the hypothalamus and closely involved in neuroendocrine functions. We now report that transcription of cyclooxygenase-2 (COX-2), the rate limiting enzyme in prostaglandin biosynthesis, was inhibited(More)
We have previously reported that TTF-1, a homeodomain-containing transcription factor, regulates circadian rhythm of pituitary adenylate cyclase-activating polypeptide gene expression in the rat hypothalamus. In this study we found that TTF-1 mRNA was specifically expressed in the rat suprachiasmatic nucleus (SCN) and colocalized with Period 2 (Per2), a(More)
CD137 is a member of the tumor necrosis factor/nerve growth factor receptor superfamily. Interaction of CD137 with its ligand (CD137L) affects the apoptosis, proliferation and differentiation of immune cells. Interestingly, the CD137 receptor/ligand system involves the bi-directional transduction of signals. The expression of CD137 and its ligand is not(More)
