The herpes simplex virus type 1 genome encodes a set of genes (alpha genes) expressed in the absence of de novo viral protein synthesis. Earlier studies have shown that the product of the alpha 22 gene, a member of this set, is nucleotidylylated by casein kinase II and phosphorylated by viral protein kinases encoded by UL13 and US3. Mutants lacking the(More)
Alzheimer's disease is characterized by deposition of beta-amyloid peptide (Abeta) into plaques in the brain, leading to neuronal toxicity and dementia. Human immunodeficiency virus type 1 (HIV-1) infection of the central nervous system can also cause a dementia, and amyloid deposition in the central nervous system is significantly higher in HIV-1-infected(More)
To elucidate the mechanisms by which Epstein-Barr virus (EBV) latency III gene expression transforms primary B lymphocytes to lymphoblastoid cell lines (LCLs), the associated alterations in cell gene expression were assessed by using 4,146 cellular cDNAs arrayed on nitrocellulose filters and real-time reverse transcription-PCR (RT-PCR). A total of 1,405 of(More)
Epstein-Barr virus (EBV) latency III infection converts B lymphocytes into lymphoblastoid cell lines (LCLs) by expressing EBV nuclear and membrane proteins, EBNAs, and latent membrane proteins (LMPs), which regulate transcription through Notch and tumor necrosis factor receptor pathways. The role of NF-kappa B in LMP1 and overall EBV latency III(More)
STAT6 is a central mediator of IL-4-induced gene responses. STAT6-mediated transcription is depend ent on the C-terminal transcription activation domain (TAD), but the mechanisms by which STAT6 activates transcription are poorly understood. Here, we have identified the staphylococcal nuclease (SN)-like domain and tudor domain containing protein p100 as a(More)
Increased metabolism is a requirement for tumor cell proliferation. To understand the dependence of tumor cells on fatty acid metabolism, we evaluated various nodes of the fatty acid synthesis pathway. Using RNAi we have demonstrated that depletion of fatty-acid synthesis pathway enzymes SCD1, FASN, or ACC1 in HCT116 colon cancer cells results in(More)
The aerobic respiratory chain of Escherichia coli is branched and contains two terminal oxidases. The chain predominant when the cells are grown with low aeration terminates with the cytochrome d terminal oxidase complex, and the branch present under high aeration ends with the cytochrome o terminal oxidase complex. Previous work has shown that cytochrome d(More)
The herpes simplex virus infected-cell protein 0 (ICP0) acts as a promiscuous transactivator of genes introduced into eukaryotic cells by transfection or infection. The protein is highly posttranslationally modified by phosphorylation and nucleotidylylation. We have examined the electrophoretic mobility and phosphorylation of ICP0 in Vero and rabbit skin(More)
The products, RNA or proteins, of the herpes simplex virus 1 open reading frame U(L)43 have not been previously identified. The expression of an open reading frame antisense to U(L)43, U(L)43.5 (P. L. Ward, D. E. Barker, and B. Roizman, J. Virol. 70:2684-2690, 1996), has been reported. We report the existence of a transcript corresponding to the domain of(More)
The infected cell protein no. 0 (ICP0), the product of the alpha 0 gene, and an important herpes simplex virus 1 regulatory protein is encoded by three exons. We report that intron 1 forms a family of four stable nonpolyadenylylated cytoplasmic RNAs sharing a common 5' end but differing in 3' ends. The 5' and 3' ends correspond to the accepted splice donor(More)
