An intact nef gene is essential for rapid development of immunodeficiency in human immunodeficiency virus and simian immunodeficiency virus infections. To assess the role of nef in the immune response, mice transgenic for SIV nef were constructed and…
The induction of spongiform myeloencephalopathy by murine leukemia viruses is mediated primarily by infection of central nervous system (CNS) microglia. In this regard, we have previously shown that CasBrE-induced disease requires late, rather than…
We have sequenced about 5 kb of the Escherichia coli chromosome downstream from the tolC gene, looking for a topoisomerase gene. This region does not contain a topoisomerase gene.
Using a combination of standard cDNA library screening techniques and the Polymerase Chain Reaction (PCR) we have isolated and sequenced DNA fragments corresponding to the human reticulocyte cytochrome b5 mRNA. The reticulocyte specific sequence…
Human papillomavirus (HPV) type 18 DNA was found in an aggressively invasive adenocarcinoma tumor from a woman who had an intact hymen and denied any prior sexual intercourse. The viral DNA was detected within the tumor tissue by polymerase chain…
