Both genetic variants and messenger RNA (mRNA) expression of DNA repair and tumor suppressor genes have been investigated as molecular markers for therapy outcome. However, the phenotypic impact of genetic variants often remained unclear, thus the rationale of their use in risk prediction may be limited. We therefore analyzed genetic variants together with(More)
DNA repair plays an important role in maintaining genomic integrity, and deficiencies in repair function are known to promote cancer development. Several studies have used the individual capacity to repair DNA damage in peripheral blood lymphocytes (PBLs) as a cancer risk marker. As the cell's ability to remove DNA damage may be correlated with(More)
The majority of patients tolerate radiotherapy well, but some of them suffer from severe side effects. To find genes possibly predictive for radiosensitivity, mRNA profiles were generated before and 6h after in vitro irradiation with 5Gy. We analyzed lymphocytes from four head and neck and eight breast cancer patients with strong acute radiation toxicity(More)
Functional gastrointestinal disorders (FGID) are common, but despite their relevance in public health care, the etiology of FGID remains essentially unknown. Stress has been suggested as a pathophysiological factor in FGID. The aims of the present study were (a) to determine the prevalence of FGID in a sample of apparently healthy students, and (b) to(More)
Radiotherapy is a powerful cure for several types of solid tumours, but its application is often limited because of severe side effects in individual patients. With the aim to find biomarkers capable of predicting normal tissue side reactions we analysed the radiation responses of cells from individual head and neck tumour and breast cancer patients of(More)
The role of butyrylcholinesterase (BChE) in the progression of Alzheimer's disease (AD) has recently become more crucial. In the AD brain, selective BChE inhibitors have been demonstrated to have a beneficial effect in vivo, probably by recovering cholinergic activity and/or by restoring AChE:BChE activity ratios to the levels observed in the healthy brain.(More)
