Illumina HumanWG-6 v3.0 expression beadchip
Description
Cutaneous, acral and mucosal subtypes of melanoma were evaluated by whole-genome sequencing, revealing genes affected by novel recurrent mutations to the promoter (TERT, DPH3, OXNAD1, RPL13A, RALY, RPL18A, AP2A1), 5-UTR (HNRNPUL1, CCDC77, PES1), and 3-UTR (DYNAP, CHIT1, FUT9, CCDC141, CDH9, PTPRT) regions. TERT promoter mutations had the highest frequency of any mutation, but neither they nor ATRX mutations, associated with the alternative telomere lengthening mechanism, were correlated with greater telomere length. Genomic landscapes largely reflected ultraviolet radiation mutagenesis in cutaneous melanoma and provided novel insights into melanoma pathogenesis. In contrast, acral and mucosal melanomas exhibited predominantly structural changes, and mutation signatures of unknown aetiology not previously identified in melanoma. The majority of melanomas had potentially actionable mutations, most of which were in components of the mitogen-activated protein kinase and phosphoinositol kinase pathways.

Description
Gene expression changes were assessed from the non sun-exposed skin of the lower back of 98 healthy males aged 19-86. We show that contrary to previous thought, genome wide transcriptional activity does not display an exclusively linear correlation with ageing, but rather, in human skin, undergoes a period of significant transient change between 30 and 45 years of age. The identified transient transcriptional changes suggest a period of heightened metabolic activity and cellular damage mediated primarily through the actions of TP53 (tumour protein 53) and TNF (tumour necrosis factor). We also identified a subgroup of the population characterised by increased expression of a large group of hair follicle genes that correlates strongly with a younger age of onset and increasing severity of androgenetic alopecia.

- Affymetrix Arabidopsis ATH1 Genome Array (ath1121501)
Description
Stresses that target mitochondrial function lead to altered transcriptional responses for 100-1000s of genes genome wide, and are signalled via retrograde communication pathways within the cell. rao2 mutants contain a mutation in the NAC family transcription factor ANAC017 and cannot induce stress responsive genes (such as the mitochondrial alternative oxidase 1a) in response to mitochondrial dysfunction. We sought to define the global gene network regulated through RAO2 function in response to mitochondrial stress (mimicked through treatment of plants with antimycin A - a specific inhibitor of complex III in the mitochondrial electron transfer chain), and non-specific stress signals such as hydrogen peroxide. We have defined global stress responses that are positively and negatively mediated by RAO2 function, and show that greater than 80% of transcripts that are differentially regulated under H2O2 stress require proper functioning of ANAC017 for a normal stress responses.

Description
A transcriptomic meta-analysis of over 400 microarrays was undertaken to compare LPC lines against datasets of; muscle and embryonic stem cell lines, embryonic and developed liver (DL), and HCC. Uploaded here, is the array data from seven of the ten LPC lines used. These seven were prepared in our laboratory. The remaining LPC arrays and arrays from other tissues/cells were obtained from the GEO.
