Affymetrix Human Genome U133 Plus 2.0 Array (hgu133plus2)
Description
Microarrays were used to detail the global program of gene expression underlying differences in the organisation of inflammatory cells classified by the expression of the CD21L and IL-17A genes. Synovia were defined by the expression of the CD21L and IL-17A genes as determined by semi-quantitative PCR.
Publication Title
Co-expression of CD21L and IL17A defines a subset of rheumatoid synovia, characterised by large lymphoid aggregates and high inflammation.

- Affymetrix Mouse Genome 430 2.0 Array (mouse4302)
Description
IL-4d2 is a natural splice variant of IL-4 which lacks the region encoded by the second exon. Numerous recent reports suggested that the expression levels of IL-4d2 change in various diseases, especially those with pulmonary involvement, but the effects of IL-4d2 on the lungs in vivo have never been studied. Replication-deficient adenovirus-mediated gene delivery of mouse IL-4d2 to mouse lungs in vivo was used, and the effects compared with similar adenoviral delivery of mouse IL-4 or with infection with a NULL viral construct.
Publication Title
Alternatively spliced variants of interleukin-4 promote inflammation differentially.

Description
Reduced or absent cytotrophoblast invasion of the maternal uterine spiral arteries is a common clinical finding in studies of pregnancies complicated by preeclampsia, suggesting that the mechanisms behind invasion of these cells is perturbed. The placenta initially develops in a low oxygen environment of 1-2% oxygen until after the 10th week of pregnancy. During this time oxygen concentration exerts a major influence over trophoblast activity and, in vitro, hypoxia inducible factors are proposed to be one of many key regulators of first trimester trophoblast behaviour. We used a global gene expression microarray approach to identify signalling pathways involved in invasion of the first trimester trophoblast cell line HTR8/SVneo under hypoxic conditions where HIF-1 was active. Additionally, first trimester placental samples from different gestational age groups were labelled with anti HIF-1 and HIF-2 to evaluate whether HIFs are differentially expressed and localised across the period of development characterised by hypoxia (6-8 weeks) and maternal blood perfusion (10-12 weeks). Eighty-eight genes were differentially expressed between cells cultured in 1% oxygen (where HIF-1 was localised to the nucleus) and 5% oxygen (where HIF-1 was cytoplasmic). 65% of the genes were predicted to contain HIF-1:ARNT transcription factor binding sites. Increased nuclear localisation of HIF-1 was seen in extravillous cytotrophoblasts in early first trimester compared with late, while cellular expression of HIF-2 in the villous stroma was higher in late first trimester. While HIFs and their downstream targets are clearly induced in trophoblasts during early placental development, and in vitro hypoxic conditions, the mechanism and pathways by which invasion is increased under hypoxic conditions is not clear from the gene expression profile. Further insight beyond the transcription level is required to fully understand this complex phenomenon.

Hypoxia induced HIF-1/HIF-2 activity alters trophoblast transcriptional regulation and promotes invasion.

Description
Objective: An intronic GGGGCC-repeat expansion of C9ORF72 is the most common genetic variant of amyotrophic lateral sclerosis (ALS) and frontotemporal dementia. The mechanism of neurodegeneration is unknown, but a direct effect on RNA processing mediated by RNA foci transcribed from the repeat sequence has been proposed.

- Affymetrix Human Exon 1.0 ST Array [probe set (exon) version (huex10st)
Description
Aims: Loss of nuclear TDP-43 characterises sporadic and most familial forms of amyotrophic lateral sclerosis (ALS). TDP-43 (encoded by TARDBP) has multiple roles in RNA processing. We aimed to determine whether 1) RNA splicing dysregulation is present in lower motor neurons in ALS and in a motor neuron-like cell model, and 2) TARDBP mutations (mtTARDBP) are associated with aberrant RNA splicing using patient-derived fibroblasts.
