Neurobiology of Disease, 2012 HIV-associated neurocognitive disorder (HAND) is an increasingly common, progressive disease characterized by neuronal loss and progressively deteriorating CNS function. HIV-1 gene products, particularly gp120 and Tat elicit reactive oxygen species (ROS)

Novel Cell type-specific aptamer-siRNA delivery system for HIV-1 therapy [PDF]
, 2007 The successful use of small interfering RNAs (siRNAs) for therapeutic purposes requires safe and efficient delivery to specific cells and tissues. Here we demonstrate cell type-specific delivery of anti-HIV siRNAs via fusion to an anti-gp120 aptamer. The

High-salinity growth conditions promote tat-independent secretion of tat substrates in Bacillus subtilis [PDF]
, 2012 The Gram-positive bacterium Bacillus subtilis contains two Tat translocases, which can facilitate transport of folded proteins across the plasma membrane. Previous research has shown that Tat-dependent protein secretion in B.

Targeted Derepression of the Human Immunodeficiency Virus Type 1 Long Terminal Repeat by Pyrrole-Imidazole Polyamides [PDF]
, 2002 The host factor LSF represses the human immunodeficiency virus type 1 long terminal repeat (LTR) by mediating recruitment of histone deacetylase. We show that pyrrole-imidazole polyamides targeted to the LTR can specifically block LSF binding both in ...

Dynamic Post-Transcriptional Regulation of HIV-1 Gene Expression
Biology, 2012 Gene expression of the human immunodeficiency virus type 1 (HIV-1) is a highly regulated process. Basal transcription of the integrated provirus generates early transcripts that encode for the viral products Tat and Rev.

Activation of interleukin 2 and interleukin 2 receptor (Tac) promoter expression by the trans-activator (tat) gene product of human T-cell leukemia virus, type I. [PDF]
Proceedings of the National Academy of Sciences, 1987 Cotransfection of cDNA encoding the trans-activator gene product of human T-cell leukemia virus, type I (HTLV-I) (tat-I), which acts in trans to augment viral gene expression, has revealed strong regulatory effects of this viral protein on the inducible cellular promoters governing human interleukin 2 (IL-2) and IL-2 receptor (Tac) gene expression. The

Hyper-responsiveness to Stimulation of Human Immunodeficiency Virus-infected CD4+ T Cells Requires Nef and Tat Virus Gene Products and Results from Higher NFAT, NF-κB, and AP-1 Induction [PDF]
Journal of Biological Chemistry, 2004 A chronic state of immune hyperactivation is a feature of human immunodeficiency virus type-1 (HIV-1) infection. Studies on the molecular mechanisms by which HIV-1 can modulate the activation state of T cells indicate that both Nef and Tat can alter T cell activation.

Activation of Egr-1 expression in astrocytes by HIV-1 Tat: new insights into astrocyte-mediated Tat neurotoxicity [PDF]
, 2011 Human immunodeficiency virus type 1 (HIV-1) Tat plays an important role in HIV-associated neuropathogenesis; the underlying mechanisms are still evolving. We have recently shown that HIV-1 Tat induces expression of glial fibrillary acidic protein (GFAP),

Characterization of two new alleles at the goat CSN1S2 locus. [PDF]
, 2001 Two novel alleles at the goat CSN1S2 locus have been identified: CSN1S2(F) and CSN1S2(D). Sequence analyses revealed that the CSN1S2(F) allele is characterized by a G --> A transition at the 13th nucleotide in exon 3 changing the seventh amino acid of ...
