Pituitary adenylate cyclase-activating polypeptide (PACAP) is a neuropeptide with pleiotropic functions. We report here that PACAP-deficient (PACAP-/-) mice showed increased immobility in a forced swimming test, which was reduced by the antidepressant desipramine, to a similar extent as in wild-type mice. The atypical antipsychotic risperidone and the(More)
Pituitary adenylate cyclase-activating polypeptide (PACAP) is one of the neurotransmitters that transfers light signals from the retina to the hypothalamic suprachiasmatic nucleus (SCN) where the master clock of mammalian circadian rhythm locates, and is suggested to be implicated in the mechanism of light-induced phase shift of the circadian clock. Here,(More)
BACKGROUND The skeletal muscle is an unusual site for metastasis from renal cell carcinoma (RCC). Metastatic RCC must be differentiated from benign primary soft-tissue tumors because aggressive surgical resection is necessary. CASE PRESENTATION We present the case of a 65-year-old man with metastatic RCC in the gluteus maximus muscle (3.8 cm in diameter)(More)
Psychostimulants, including amphetamine, act as antihyperkinetic agents in humans with hyperkinetic disorder such as attention-deficit hyperactivity disorder and are known to be effective in enhancing attention-related processes; however, the underlying mechanisms have not been adequately addressed. Mice lacking the Adcyap1 gene encoding the neuropeptide(More)
We have recently shown that in PC12 cells, pituitary adenylate cyclase-activating polypeptide (PACAP) and NGF synergistically stimulate PACAP mRNA expression primarily via a mechanism involving a p38 mitogen-activated protein kinase (MAPK)-dependent pathway. Here we have analyzed p38 MAPK activation by PACAP and the mechanism underlying this action of PACAP(More)
Pituitary adenylate cyclase-activating polypeptide (PACAP) is a highly conserved neuropeptide and widely expressed in both brain and peripheral tissues, including several reproductive organs (e.g., testis and ovary). PACAP stimulates syntheses of several sexual hormones and steroids, suggesting it has possible roles in reproductive function. In this study,(More)
Metabolomics has recently undergone rapid development; however, metabolomic analysis in cerebrospinal fluid (CSF) is not a common practice. We analyzed the metabolite profiles of preoperative CSF samples from 32 patients with histologically confirmed glioma using gas chromatography/mass spectrometry (GC/MS). We assessed how alterations in the metabolite(More)
Using pituitary adenylate cyclase-activating polypeptide (PACAP)-deficient mice, we investigated whether PACAP is involved in the intoxicating effects of ethanol. The structure of PACAP is highly conserved during evolution, and in Drosophila, loss-of-function mutations in a PACAP-like neuropeptide gene, amnesiac, result in impairment of memory retention and(More)
Cartilage provides the template for endochondral ossification and is crucial for determining the length and width of the skeleton. Transgenic mice with targeted expression of recombinant cartilage-derived morphogenetic protein-1 (CDMP-1), a member of the bone morphogenetic protein family, were created to investigate the role of CDMP-1 in skeletal formation.(More)
BACKGROUND Aberrant microRNA (miRNA) expression plays an essential role in osteosarcoma (OS) pathogenesis. Recent studies have shown that dysregulation of miRNA expression is associated with increased tumorigenesis and poor prognosis in several types of cancers, including OS. The aim of this study was to investigate the relevant microRNAs involved in the(More)
