Early stages of many neurodegenerative diseases, such as Alzheimer's disease, vascular and frontotemporal dementia, and Parkinson's disease, are frequently associated with Mild Cognitive Impairment (MCI). A minimally invasive screening test for early detection of MCI may be used to select optimal patient groups in clinical trials, to monitor disease(More)
Members of the Bcl-2 family of proteins are characterized by their ability to modulate cell death. Bcl-2 and some of its homologues inhibit apoptosis, whereas other family members, such as Bax, will accelerate apoptosis under certain conditions. Here we describe the identification and characterization of a complementary DNA that encodes a previously unknown(More)
Many neurodegenerative diseases, such as Alzheimer's disease, Parkinson disease, vascular and frontotemporal dementias, as well as other chronic neurological pathologies, are characterized by slow development with a long asymptomatic period followed by a stage with mild clinical symptoms. As a consequence, these serious pathologies are diagnosed late in the(More)
Of six prostatic carcinoma cell lines examined (ALVA31, DU145, JCA1, LNCaP, ND1, and PC3) by flow cytometric analysis, all were found to be positive for Fas antigen. Furthermore, of the prostate tissue specimens studied (six cases), all revealed Fas expression in benign and malignant epithelial cells. The agonistic anti-Fas monoclonal antibody (IPO-4)(More)
A minimally invasive test for early detection and monitoring of Alzheimer's and other neurodegenerative diseases is a highly unmet need for drug development and planning of patient care. Mild Cognitive Impairment (MCI) is a syndrome characteristic of early stages of many neurodegenerative diseases. Recently, we have identified two sets of circulating(More)
BACKGROUND Fragments of DNA from cells dying throughout the body are detectable in urine (transrenal DNA, or Tr-DNA). Our goal was the optimization of Tr-DNA isolation and detection techniques, using as a model the analysis of fetal DNA in maternal urine. METHODS We isolated urinary DNA using a traditional silica-based method and using a new technique(More)
Early disease detection with a minimally invasive screening test will significantly increase effectiveness and decrease the cost of treatment. Here we propose a framework of a novel approach – Universal Screening Test (UST) for the detection of pathological processes in a particular organ system, organ, or tissue by RT-qPCR analysis of circulating cell-free(More)
The phenomenon of aging is distinct from processes associated with advanced age known to increase risk of diseases, such as cancer. Furthermore, the process of aging is not necessarily related to phenomena such as in vitro replicative senescence; however, any unifying hypothesis of aging must account for all age-dependent phenomena, including senescence. It(More)
In this issue of Clinical Chemistry, Hung et al. describe the results of a study originally devoted to investigation of the transrenal DNA (Tr-DNA) 1 phenomenon. These authors report on the presence of donor-derived, cell-free DNA and cells in the urine of sex-mismatched hematopoietic stem cell transplant (HSCT) recipients (1). The term Tr-DNA defines DNA(More)
