Description
In this study, we used RNA-sequencing to profile the long non-coding RNA (lncRNA) transcriptome in lesional skin from psoriasis patients before (PP) and after treatment (PT) with adalimumab and in normal skin from healthy individuals (NN). For this we sequenced total RNA from 18 psoriasis patients (before and after treatment) and 16 healthy controls. We created our own reference set of long non-coding RNAs by merging three long non-coding RNA reference data sets. The combined reference had 67,157 lncRNA transcripts with no overlaps. We identified differential expression of 971 lncRNAs between PP and NN, 157 between PP and PT, and 377 between PT and NN. Based on differentially expressed (DE) lncRNAs between PP and NN, we identified a molecular lncRNA signature that distinguishes psoriatic skin from healthy skin . Overall design: We recruited 18 psoriatic patients in our study. We took 5 mm punch biopsies from the edge of a psoriatic plaque before treatment and after one month of treatment with adalimumab. The mean improvement in the PASI over this time period was 53.1%. We obtained sixteen normal skin samples (N=16) from healthy control surgical discard specimens.

Affymetrix Mouse Genome 430 2.0 Array (mouse4302)
Description
Astrocytes react to brain injury in a heterogeneous manner with only a subset resuming proliferation and acquiring in vitro neural stem cell properties. In order to identify novel regulators of this astrocyte subset, we performed a genome-wide expression analysis of reactive astrocytes isolated 5 days after stab wound injury from the adult mouse cerebral cortex. The expression pattern was compared with astrocytes from normal cortex and adult neural stem cells isolated from the sub-ependymal zone (GSE18765). These comparisons revealed a set of genes up-regulated both in neurogenic neural stem cells and reactive astrocytes, including the lectins Galectin-1 and -3. These results, as well as the pattern of Galectin expression in the lesioned brain, led us to examine the functional significance of these lectins in brains of Galectin-1/3 double-knockout mice.

Description
Human rhinoviruses (HRV) are among the most common causes of respiratory infections in humans but can be frequently detected also in asymptomatic subjects. We evaluated the value of gene expression profiles to differentiate asymptomatic detection from symptomatic HRV infection in children.

- Affymetrix Yeast Genome 2.0 Array (yeast2)
Description
Dynamic mRNA gene expression from the wildtype YSBN6 during a nutritional downshift from glutamine to proline. Glutamine and proline were initially together in the media, with cells consuming exlusively glutamine (proline utilization inhibited due to nitrogen catabolite repression). The concentration of glutamine was frequently evaluated at-line, and the moment at which glutamine was not detected anymore is referred to as the time of the shift.

- 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.

- Affymetrix Mouse Gene 1.0 ST Array (mogene10st)
Description
Macrophage inflammatory protein 1alpha/CCL3 protein is a known pro-inflammatory cytokine that can mediate chemotaxis of monocytes and promote cell degranulation. Ccl3 gene expression is elevated in the CNS and visceral tissue of many lysosomal storage disorders. The deletion of Ccl3 in a mouse model of Sandhoff disease was reported to result in reduced monocyte-associated pathology in the brain, delayed neurodegeneration, and prolonged health. However, deletion of Ccl3 in a mouse model of Niemann-Pick C disease was dentrimental or neutral instead of beneficial. Prevention of neuronal loss was instead mediated by providing NPC1 to neurons.
