Recombinant human phenylalanine hydroxylase (hPAH) was produced in high yields in Escherichia coli using the pET and pMAL expression vectors. In the pMAL system, hPAH was fused through the target sequences of the restriction protease factor Xa (IEGR) or enterokinase (D4K) to the C-terminal end of the highly expressed E. coli maltose-binding protein (MBP).(More)
Familial breast-ovarian cancer has been demonstrated to be frequent but unevenly distributed in Norway. This was assumed to be caused by the reduced population size created by the medieval Bubonic plagues 25 generations ago, and by the following rapid expansion. We have previously reported that four mutations account for 68% of the BRCA1 mutation carriers.(More)
Women with a family history of breast cancer are commonly offered regular clinical or mammographic surveillance from age 30. Data on the efficacy of such programmes are limited. Clinical, pathological and outcome data were recorded on all breast and ovarian cancers diagnosed within familial breast cancer surveillance programmes at collaborating centers in(More)
Dedicated clinics have been established for the early diagnosis and treatment of women at risk for inherited breast cancer, but the effects of such interventions are currently unproven. This second report on prospectively diagnosed inherited breast cancer from the European collaborating centres supports the previous conclusions and adds information on(More)
Several studies of survival in women with BRCA1 mutations have shown either reduced survival or no difference compared to controls. Programmes for early detection and treatment of inherited breast cancer, have failed to demonstrate a significant improvement in survival in BRCA1 mutation carriers.One hundred and sixty-seven women with disease-associated(More)
AIM To assess the effectiveness of annual ovarian cancer screening (transvaginal ultrasound and serum CA125 estimation) in reducing mortality from ovarian cancer in women at increased genetic risk. PATIENTS AND METHODS A cohort of 3532 women at increased risk of ovarian cancer was screened at five European centres between January 1991 and March 2007.(More)
Inherited breast cancer is a heterogenous group of diseases. We examined this heterogeneity in a prospective series of inherited breast and ovarian cancers, previously demonstrated to include 84% of inherited cancers. Ninety-two tumours (65 breast and 27 ovarian) in 82 patients from 70 kindreds were prospectively diagnosed. Fifteen of the breast cancers(More)
Ten BRCA mutations were demonstrated to be frequent in the Norwegian population. We present maps verifying the uneven distribution of prevalences according to municipality. We tested incident breast cancer cases treated in Mid-Norway from 1999 onwards for these mutations. Uptake of testing was 97% and 2.5% were demonstrated to be mutation carriers. Ten(More)
We wanted to compare the sensitivities of breast magnetic resonance imaging (MRI) and the conventional screening programme consisting of mammography (XRM) +/- ultrasound for early diagnosis of breast cancer in BRCA1/2 mutation carriers. BRCA1/2 mutation carriers were examined prospectively by both breast MRI and XRM +/- ultrasound. Eight hundred and(More)
