We have found that the microsatellite marker AFM207zg5 (DXS995) maps to all previously described deletions which are associated with X-linked mixed deafness (DFN3) with or without choroideremia and mental retardation. Employing this marker and pHU16 (DXS26) we have identified two partially overlapping yeast artificial chromosome clones which were used to(More)
Aging is associated with impaired mitochondrial function caused by accumulation of oxygen free radical-induced mitochondrial (Mt) DNA mutations. One prevailing theory is that age-associated diseases, including Alzheimer's disease (AD), may be precipitated, propagated, or caused by impaired mitochondrial function. To investigate the role of MtDNA relative to(More)
The matrix protein M1 of influenza virus A/WSN/33 was shown by immunofluorescent staining to be transported into the nuclei of transfected cells without requiring other viral proteins. We postulated the existence of a potential signal sequence at amino acids 101 to 105 (RKLKR) that is required for nuclear localization of the M1 protein. When CV1 cells were(More)
The membrane-binding affinity of the matrix (M) protein of vesicular stomatitis virus (VSV) was examined by comparing the cellular distribution of wild-type (wt) virus M protein with that of temperature-sensitive (ts) and deletion mutants probed by indirect fluorescent-antibody staining and fractionation of infected or plasmid-transfected CV1 cells. The(More)
The long-term propagation ofprimary human prostate cancer (PCA)in vivo or in vitro has been rare. Most such PCAS are phenotypically different from most PCAs in humans; i.e., they make little prostate specific antigen and respond little, if at all, to androgen deprivation. A serially transplant able, primary human PCA, designated CWR22, exhibits a clonal(More)
Staphylococcal enterotoxin B and related toxins that target T cells have the capacity to elicit systemic inflammation, tissue injury, and death. Genes that encode mediators of inflammation can be globally inhibited by blocking the nuclear import of stress-responsive transcription factors. Here we show that cell-permeant peptides targeting Rch1/importin(More)
In-use testing of disinfectants is necessary to ensure efficacy over time. The current official procedure for testing disinfectants, the Association of Official Analytical Chemists (AOAC) use-dilution method, cannot be adapted to repeated sampling techniques of use-life testing. It is therefore necessary to use an alternative method when evaluating the(More)
Convincing epidemiological data suggest an inverse association between cancer and neurodegeneration, including Alzheimer's disease (AD). Since both AD and cancer are characterized by abnormal, but opposing cellular behavior, i.e., increased cell death in AD while excessive cell growth occurs in cancer, this motivates us to initiate the study into unraveling(More)
