Affymetrix Mouse Genome 430 2.0 Array (mouse4302)
Description
We present a microarray analysis of primary mouse astrocytes exposed to HIV-1 in culture. Results are compared with previous genomic studies of HIV-1 effect in human astrocytes and human and macaque brains.
Publication Title
Gene expression profiles of HIV-1-infected glia and brain: toward better understanding of the role of astrocytes in HIV-1-associated neurocognitive disorders.

- Affymetrix Human Genome U133 Plus 2.0 Array (hgu133plus2)
Description
Antiretroviral therapy (ART) has reduced morbidity and mortality in HIV infection; however HIV-1-associated neurocognitive disorders (HAND) persist despite treatment. We used microarray analysis in post-mortem brain tissues to determine ART effectiveness in the brain and to identify molecular signatures of HAND under ART.

Significant effects of antiretroviral therapy on global gene expression in brain tissues of patients with HIV-1-associated neurocognitive disorders.

Illumina HiSeq 4000
Description
Transcription termination and mRNA export from the nucleus are closely regulated and coordinated processes. Nuclear export factors are recruited to actively transcribed genes through their interactions with protein complexes associated with transcription and co-transcriptional pre-mRNA processing. We determine a new role for the kinase WNK1 in the cross-talk of transcription termination and mRNA export. WNK1 was previously attributed a cytoplasmic role as a regulator of ion transport. However, we now show a nuclear function for this kinase where it is required for efficient mRNA export along with the transcription termination factor PCF11. Finally, we identify the phosphorylation of the CID domain of PCF11 as an important step for the release of the mRNA from the transcription locus, thus allowing efficient mRNA export to the cytoplasm. Overall design: RNA from cytoplasmic and nuclear extracts of HeLa cells was obtained, upon depletion of WNK1 kinase or from control cells. Upon pA selection, libraries were generated and sequenced. A duplicate experiment was performed for each sample.

WNK1 kinase and the termination factor PCF11 connect nuclear mRNA export with transcription.

- Affymetrix Mouse Expression 430A Array (moe430a)
Description
We undertook a survey of gene expression changes in primary microglial cultures with and without neurovirulent (FrCasE) and non-neurovirulent (Fr57E) virus infection to identify physiological changes that could be relevant to the induction of spongiform neurodegeneration. These gene expression analyses were performed using Affymetrix 430A mouse GeneChips (5 chips for each of the three experimental conditions, representing over 14,000 murine genes and ESTs. RNA from 5 separate microglial culture preparations were analyzed for Control (mock infected), Fr57E-, and FrCasE-infected microglia. Present/absent calls were based on MicroArray Suite 5.0 from Affymetrix. Affymetrix CEL files were analyzed using dChip software after normalization of the data between all 15 arrays. Statistical analyses were performed using ANOVA.

Description
Restricted feeding impacts the hepatic circadian clock of WT mice. Cry1, Cry2 double KO mice lack a circadian clock and are thus expected to show rhythmical gene expression in the liver. Imposing a temporally restricted feeding schedule on these mice shows how the hepatic circadian clock and rhythmic food intake regulate rhythmic transcription in parallel
