Using morpholino antisense oligonucleotide (MO) technology, we blocked leptin A or leptin receptor expression in embryonic zebrafish, and analyzed consequences of leptin A knock-down on fish development. Embryos injected with leptin A or leptin…

A simple approach is described to synthesize and clone an inexhaustible supply of any homozygous and/ or heterozygous controls diluted with yeast genomic DNA to mimic human genome equivalents for use throughout the entire multiplex mutation assay. As…

Odontocetes and mysticetes are two extant suborders of cetaceans. It is reported that the former have no sense of olfaction, while the latter can smell in air. To explain the ecological reason why mysticetes still retain their sense of smell, two…

WDR45 and POLR3A are newly recognized genes; each is associated with a distinct neurodegenerative disease. WDR45 is an X-linked gene associated with a dominant form of Neurodegeneration with Brain Iron Accumulation (NBIA), manifested by progressive…

A unique phenotype of Waardenburg-Hirschsprung disease (WS4) accompanied by peripheral neuropathy and central dysmyelination has been recognized recently in association with SOX10 mutations. We report an infant boy with lethal congenital…

In primary cultures of adult rat hepatocytes the level of cholesterol 7-alpha-hydroxylase steady-state mRNA markedly decreased by 72 h. However, the addition of L-thyroxine (T4) and dexamethasone synergistically returned cholesterol…

COL27A1 is a member of the collagen fibrillar gene family and is expressed in cartilaginous tissues including the anlage of endochondral bone. To begin to understand its role in skeletogenesis, the temporospatial distributions of its RNA message and…

The cholesterol 7 alpha -hydroxylase gene (CYP7A1) plays an important role in regulation of bile acid biosynthesis and cholesterol homeostasis. Oxysterol receptor, LXR, stimulates, whereas the bile acid receptor, FXR, inhibits CYP7A1 transcription.…

Mitochondrial sterol 27-hydroxylase (CYP27Al) catalyses sterol side-chain oxidation of bile acid synthesis front cholesterol, and the first reaction of the acidic bile acid biosynthetic pathway. Hydrophobic bile acids suppress human CYP27Al gene…

In primary cultures of rat hepatocytes, transcription of the cholesterol 7 alpha-hydroxylase gene is induced synergistically by glucocorticoid and thyroid hormones. The objective of the present study was to evaluate the role of glucocorticoid and…

Six squamous cell carcinomas of the vulva (SCV) were karyotyped in short-term culture and in early passages as established cell lines. Each tumor was cytogenetically distinct, contained multiple chromosome rearrangements, and was karyotypically…

The pathogenesis of Crohn's disease (CD), an idiopathic inflammatory bowel disease, is attributed, in part, to intestinal bacteria that may initiate and perpetuate mucosal inflammation in genetically susceptible individuals. Paneth cells (PC) are the…

The mechanism of antiviral action of tricyclodecan-9-yl-xanthogenate (D609) was investigated in vitro. D609 inhibited herpes simplex virus type 1 (HSV-1) replication without apparent cytotoxicity. It reduced phosphorylation of virus-infected cell…

AGS1/RASD1 is a Ras-related protein identified as a dexamethasone-inducible cDNA and as a signal regulator in various functional and protein-interaction screens. As an initial approach to define the role of AGS1/RASD1 as a Ras-family member, we…
