Human papillomaviruses (HPV) are associated with nearly all cervical cancers, 20% to 30% of head and neck cancers (HNC), and other cancers. Because HNCs also arise in HPV-negative patients, this type of cancer provides unique opportunities to define similarities and differences of HPV-positive versus HPV-negative cancers arising in the same tissue. Here, we(More)
MicroRNAs (miRNAs) posttranscriptionally regulate targeted messenger RNAs (mRNAs) by inducing cleavage or otherwise repressing their translation. We address the problem of detecting m/miRNA targeting relationships in homo sapiens from microarray data by developing statistical models that are motivated by the biological mechanisms used by miRNAs. The focus(More)
Brome mosaic virus (BMV) protein 1a has multiple key roles in viral RNA replication. 1a localizes to perinuclear endoplasmic reticulum (ER) membranes as a peripheral membrane protein, induces ER membrane invaginations in which RNA replication complexes form, and recruits and stabilizes BMV 2a polymerase (2a(Pol)) and RNA replication templates at these sites(More)
To identify the molecular mechanisms by which EBV-associated epithelial cancers are maintained, we measured the expression of essentially all human genes and all latent EBV genes in a collection of 31 laser-captured, microdissected nasopharyngeal carcinoma (NPC) tissue samples and 10 normal nasopharyngeal tissues. Global gene expression profiles clearly(More)
Polymorphisms in nitrosamine metabolism, DNA repair, and immune response genes have been associated with nasopharyngeal carcinoma (NPC). Studies have suggested chromosomal regions involved in NPC. To shed light on NPC etiology, we evaluated host gene expression patterns in 31 NPC and 10 normal nasopharyngeal tissue specimens using the Affymetrix Human(More)
Multiple conflicting findings have been presented which indicate that EBV may be found in anywhere from 0% to 51% of breast carcinomas. When EBV has been found causally associated with other human cancers, its DNA and one or more of its viral products have been detected in most tumor cells of a given biopsy. To test whether EBV has such an association with(More)
The nucleotide sequence of the nucleocapsid (N) protein gene of Berne virus (BEV; proposed family Toroviridae) was determined from two independent clones of a cDNA library. From the deduced amino acid sequence a basic protein of 18.3K was predicted. In vitro transcription and translation, followed by immunoprecipitation, were used to identify the gene. The(More)
