The tumour suppressor gene p53 has been found to be mutated or inactivated at high frequency in several common human tumours. We have examined a series of exocrine pancreatic carcinomas for over-expression of mutant forms of p53 by immunohistochemistry with a panel of specific antibodies. We found immunodetectable p53 in 13 of 22 (60%) frozen pancreatic(More)
The objective of this study was to examine whether the functional genetic polymorphism Val158Met in the catechol-O-methyltransferase (COMT) gene influences cognitive deterioration in a sample of patients with psychosis under treatment with atypical antipsychotics. Eighty-seven patients with psychosis were genotyped for this polymorphism and were assessed(More)
Pharmacogenetic research has identified response-related mutant variants in metabolic enzymes and drug-targeted receptors. Allelic variants of dopaminergic and serotonergic receptors have been associated with clinical outcome and adverse events such as movement disorders. Deficient metabolic enzymes have been related to drug accumulation and toxic events.(More)
OBJECTIVE In the study of bipolar affective disorder and schizophrenia, there is some evidence suggesting a phenotypic and genetic overlap between the two disorders. A possible link between bipolar affective disorder and schizophrenia remains arguable, however. The authors hypothesized that dysbindin, which is a probable susceptibility gene for(More)
Minocycline possesses anti-inflammatory properties independently of its antibiotic activity although the underlying molecular mechanisms are unclear. Lipopolysaccharide (LPS)-induced cytokines and pro-inflammatory protein expression are reduced by minocycline in cultured macrophages. Here, we tested a range of clinically important tetracycline compounds(More)
Past laboratory and field studies show that the effort necessary to obtain food acts as a determinant of food selection and consumption. Two studies examined the impact of increasing the effort needed to obtain candy or potato chips on selection in a normal lunch setting. In the first study, food selection, acceptance and intake were obtained during the(More)
The expression of the EGF receptor, c-erbB-2 and PDGF receptor proteins has been studied in a series of human brain tumour biopsies and cell lines. Western blotting was used to determine the amount of protein present and their intrinsic and ligand promoted enzyme activities were studied by immunoprecipitation followed by autophosphorylation. EGF receptors(More)
There are several lines of evidence implicating the dopamine D3 receptor in the pathophysiology of schizophrenia. The Ser9Gly polymorphism of the dopamine D3 receptor gene (DRD3) has been the most extensively investigated DRD3 variant in connection with the disease but results have been inconclusive. Recent reports indicate that the Ser9Gly polymorphism is(More)
