A new full-length cDNA (ZFOR4) that encodes an opioid receptor has been isolated from the teleost zebrafish. The encoded polypeptide is 375 amino acids long and shows high sequence similarity to other delta-opioid receptors, including ZFOR1, the other delta-opioid receptor from zebrafish previously characterized by us. In situ hybridization studies have(More)
Mutations in the PARKIN gene have been identified in families with recessively inherited Parkinson disease (PD). Common DNA-polymorphisms at the PARKIN gene could contribute to the risk for PD in the general population. Here we searched for DNA-polymorphisms in the PARKIN promoter. We found two single nucleotide polymorphisms (-324 A/G and -797 A/G). In(More)
In addition to its well-established effect on T cells, cyclosporin A (CsA) also inhibits inflammatory cytokine production by macrophages. However, little is known about the mechanism of action of CsA on macrophage cytokine production. We measured the effect of CsA on basal and phorbol-myristate-acetate (PMA)-stimulated production of interleukin-6 using the(More)
Partial thyroxine-binding globulin deficiency (TBG-PD) is an endocrine defect with a prevalence of 1:4 000 in newborns. Due to the presence of a single TBG gene on the X chromosome, most familial TBG defects follow an X-linked inheritance pattern. Abnormal T4 binding to T4-binding prealbumin (TTR) is a rare cause of euthyroid hyperthyroxinemia, which is(More)
Breast carcinoma is a public health problem worldwide. It is known that both genetic and environmental factors are important for breast carcinogenesis and that structural and/or functional alterations at p53 gene are commonly observed in breast tumors. In addition, polymorphisms of several genes in either their coding or non-coding sequences have been found(More)
We have synthesized and assayed dimethylaminophenyl, pyrrolidin-1-ylphenyl and carbazole containing phenstatins and isocombretastatins as analogues of the highly potent indoleisocombretastatins with extended or reduced ring sizes. This is an attempt to explore beyond the structural constraints of the X-ray crystal structures the zone of the colchicine site(More)
Autosomal dominant polycystic kidney disease is a multi-organic hereditary disorder. It is responsible for 7-10% of cases of end stage renal failure. It is caused by mutations in the genes PKD1 and PKD2. Both polycystic kidney disease's forms have a pathogeny and similar clinic, but in the patients with mutation in PKD2, the clinical manifestations appear(More)
BACKGROUND Two or more primary colorectal tumors coexisting at the time of diagnosis are considered to be synchronous tumors. It is estimated that synchronous colorectal cancer (SCRC) only accounts for 1.1% to 8.1% of all colorectal cancers (CRCs), and its molecular basis is still poorly understood. PATIENTS AND METHODS We evaluated the microsatellite(More)
