Illumina MouseRef-8 v2.0 expression beadchip
Description
Liposarcoma is a poorly understood malignancy of fat cells. Lipolysis, a central pathway of adipose tissue metabolism, has been implicated in cancer. Here, we generated tissue-specific single- and combined knockout mice for the two major lipases ATGL and HSL. Notably, double knockout (DAKO) mice developed late onset liposarcoma with complete penetrance, while single knockout mice appeared normal. DAKO whole transcriptome profiles differed from those of single knockout mice, revealing an early-onset tissue-specific response that persisted until the late-onset development of liposarcoma. Cancer-associated markers Gpnmb and G0s2 were among the most highly dysregulated genes in DAKO mice and also in human liposarcomas, suggesting a potential role for these proteins as liposarcoma-specific biomarkers. Taken together, our results demonstrate a novel epistatic interaction linking lipolysis with cancer. DAKO mice provide a promising model for studying early premalignant changes that lead to late-onset disease.

- Affymetrix Human Genome U133 Plus 2.0 Array (hgu133plus2)
Description
To obtain a separation of the epidermal and dermal compartments in order to examine compartment specific biological mechanisms in the skin we incubated 4 mm human skin punch biopsies in ammonium thiocyanate (NH4SCN). We wanted to test 1) the histological quality of the dermo-epidermal separation obtained by different incubation times 2) the amount and quality of extractable epidermal RNA, and 3) its impact on sample RNA expression profiles assessed by large-scale gene expression microarray analysis in both normal and inflamed skin. At 30 minutes incubation, the split between dermis and epidermis was not always histologically well-defined (i.e. occurred partly intra-epidermally) but varied between subjects. Consequently, curettage along the dermal surface of the biopsy was added to the procedure. This modified method resulted in an almost perfect separation of the epidermal and dermal compartments and satisfactory amounts of high-quality RNA were obtained. Hybridization to Affymetrix HG_U133A 2.0 GeneChips showed that ammonium thiocyanate incubation had a minute effect on gene expression resulting in only one significantly downregulated gene (cystatin E/M). We conclude that epidermis can be reproducibly and almost completely separated from the dermis of 4 mm skin biopsies by 30 min incubation in 3.8% ammonium thiocyanate combined with curettage of the dermal surface, producing high-quality RNA suitable for transcriptional analysis. Our refined method of dermo-epidermal separation will undoubtedly prove valuable in the many different settings, where the epidermal and dermal compartments need to be evaluated separately.

- Affymetrix Drosophila Genome 2.0 Array (drosophila2)
Description
Classical regeneration experiments in insects have demonstrated an important role for imaginal tissues (also called discs, the larval tissues that give rise to the adult appendages) in coupling tissue growth, maturation and patterning during development We used the rotund-Gal4 driver (Rn>) for disc-targeted silencing of the avalanche gene (avl; Rn>avl-RNAi), encoding a syntaxin that functions in the early endocytic machinery (H. Lu, D. Bilder, Nat Cell Biol 7, 1232; Dec, 2005). Rn>avl-RNAi discs reach near to normal size after 5 days of development, and then undergo unrestricted neoplastic growth. We were interested in identifying genes showing differential expression profiles in control and in neoplastic growth. We identified dilp8 as one of the most differentially expressed gene in control and Rn>avl-RNAi discs.

- Affymetrix Human Genome U133A Array (hgu133a)
Description
The purpose of this experiment was to identify oestrogen regulated genes in human primary cell cultures of neuronal and glial cells modelling the developing human nervous system. We were especially interested in genes involved in proliferation, differentiation and migration of neuronal cells and genes involved in or linked to neurodegenerative diseases. We have therefore assessed gene expression changes, using Affymetrix GeneChips (HG-U133A), of oestrogen treated human neuronal/ glial cell cultures. We continued with 14 selected genes and confirmed the gene expression changes, by relative quantitative real time PCR, of 6 genes (p< 0.05) important in neuronal development, three of which also are suggested to have links to neurodegenerative diseases.
