Variable number tandem repeats (VNTR) within non-coding regions of a number of genes have been correlated with susceptibility to various disease states. In particular, a VNTR polymorphism of a 16 or 17 bp element within intron 2 of the human serotonin transporter gene has been correlated with a predisposition to affective disorders. We have demonstrated… (More)
[Arginine]vasopressin (AVP) is a neuropeptide physiologically synthesized in the hypothalamus but pathologically expressed by small-cell lung cancer (SCLC). A minimal 65 bp AVP promoter can restrict basal activity to SCLC in vitro, but a 199 bp fragment directs 5-fold higher expression in SCLC [Coulson, Stanley and Woll (1999) Br. J. Cancer 80, 1935-1944].… (More)
OBJECTIVE To assess whether substance P and the corresponding neurokinin 1 (NK1) receptor are expressed in human articular cartilage, and whether these molecules have a role in chondrocyte mechanotransduction. METHODS Transgenic studies, immunohistochemistry, Western blotting, and reverse transcriptase-polymerase chain reaction were used to assess the… (More)
The antiplatelet drug ticlopidine was assessed as an agent for improving the patency of Brescia-Cimino arteriovenous fistulas as access for hemodialysis. In a double-blind randomized study over 1 month, two of six fistulas in the ticlopidine group and five of nine in the placebo group failed. A further one placebo and two ticlopidine patients still had… (More)
The dopamine (DAT) and serotonin (SERT) transporter genes both contain variable number of tandem repeats (VNTR) in non-coding gene regions which have been correlated with a predisposition to a variety of CNS disorders. There is considerable homology between individual DAT and SERT repeat DNA sequences, which is reflected in their ability to compete with… (More)
Following the establishment of a chronic varicella-zoster virus infection in the rat, behavioural allodynia and hyperalgesia were observed in the injected, but not the contralateral hind limb up to 33 days post-infection. This model may prove useful in investigating mechanisms involved in the establishment of post-herpetic neuralgia.
Arginine vasopressin (AVP) is often expressed in small cell lung cancer (SCLC), and a 65-bp AVP minimal promoter fragment is sufficient to restrict activity to SCLC in vitro. We now describe a motif with homology to the neuron-restrictive silencer element (NRSE) within this fragment. Electrophoretic mobility shift analysis demonstrated that multiple… (More)
We have demonstrated that a variable number tandem repeat domain (VNTR) within intron 2 of the serotonin transporter gene is a transcriptional regulatory domain which is potentially correlated with a predisposition to affective disorders and other behavioural conditions. This correlation based on copy number of the VNTR alone (nine, 10 or 12 copies of 16/17… (More)
We have recently developed cell line models that express the endogenous rat preprotachykinin-A (rPPT) gene and support reporter gene expression directed by the rPPT promoter. These are the neuronal derived cell line NF2C and the pancreatic cell lines RINm5F and a derivative RIN-1027-B2. Reporter gene activity in these cell lines is similar to that observed… (More)
Sera from eight of 17 patients with acute viral hepatitis was deficient in its ability to support neutrophil bactericidal function in vitro. This defect appeared to be related to the viral infection itself. Sera from patients with drug hepatitis or mechanical obstructive jaundice did not show this effect.
