Affymetrix Human Genome U133 Plus 2.0 Array (hgu133plus2)
Description
A consistent clinical feature of amyotrophic lateral sclerosis (ALS) is the sparing of eye movements. Pathological studies have confirmed that there is relative sparing of the cranial motor nuclei of the oculomotor, trochlear and abducens nerves, although pathological changes resembling those seen in anterior horn cells are present to a lesser degree. The aim of the present study is to combine LCM and microarray analysis to study the differences between motor neurons that are selectively resistant (oculomotor neurons) and those that are vulnerable (lumbar spinal motor neurons) to the disease process in amyotrophic lateral sclerosis.
Publication Title
Unravelling the enigma of selective vulnerability in neurodegeneration: motor neurons resistant to degeneration in ALS show distinct gene expression characteristics and decreased susceptibility to excitotoxicity.

Description
Gene expression profiling has been performed on astrocytes isolated using laser capture microdissection (LCM) from multiple sclerosis normal appearing white matter (NAWM) and control WM to identify whether specific glial changes exist in NAWM which contribute to lesion development or prevent disease progression

- Affymetrix Human Genome U133 Plus 2.0 Array (hgu133plus2)
Description
Gene expression profiling has been performed previously on motor cortex and spinal cord homogenates and of sporadic ALS cases and controls, to identify genes and pathways differentially expressed in ALS. More recent studies have combined the use of laser capture microdissection (LCM) with gene expression profiling to isolate the motor neurons from the surrounding cells, such as microglia and astrocytes, in order to determine those genes differentially expressed in the vulnerable cell population i.e. motor neuron.

- 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.

Description
Astrocyte dysfunction impacts their normal function, including neuronal support, thereby contributing to neurodegenerative pathologies including Alzheimer's disease (AD). Therefore to understand the role of astrocytes in the pathogenesis of age-related disorders we analysed the gene expression profile of astrocytes with respect to Alzheimer-type pathology.
