Affymetrix Mouse Gene 1.0 ST Array (mogene10st)
Description
MacroH2As core histone variants have a unique structure that includes C-terminal nonhistone domain. MacroH2As are highly conserved in vertebrates, and are thought to regulate gene expression. However the nature of genes regulated by macroH2As and the biological significance of macroH2As for the organism remain unclear. Here we examine macroH2A function in vivo by knocking out both macroH2A1 and macroH2A2 in the mouse.

Description
Background: MicroRNA-196b-5p (miR-196b-5p) has been previously involved in carcinogenesis, though its role in colorectal cancer (CRC) patients and biology remains controversially. In our current study, we systematically explored the clinical significance and biological relevance of miR-196b-5p, as well as the underlying molecular mechanisms regulated by miR-196b-5p in colorectal cancer.

- Affymetrix Rat Genome 230 2.0 Array (rat2302)
Description
Amyotrophic lateral sclerosis (ALS) is caused by the progressive degeneration of motor neurons. Mutations in the Cu/Zn superoxide dismutase (SOD1) are found in about 20% of patients with familial ALS. Mutant SOD1 causes motor neuron death through an acquired toxic property. Although, molecular mechanism underlying this toxic gain-of-function remains unknown, evidence support the role of mutant SOD1 expression in non-neuronal cells in shaping motor neuron degeneration. We have previously found that in contrast to non-transgenic, SOD1G93A-expressing astrocytes induced apoptosis of co-cultured motor neurons. This prompted us to investigate whether the effect on motor neuron survival was related to a change in the gene expression profile. Through high-density oligonucletide microarrays we found changes in the expression of genes involved in transcription, signaling, cell proliferation, extracellular matrix construction, response to stress and steroid and lipid metabolism. Decorin, a small multifunctional proteoglycan, was the most up-regulated gene. Down-regulated genes included the insulin-like growth factor-1 receptor and the RNA binding protein ROD1. We also analyzed the expression of selected genes in purified motor neurons expressing SOD1G93A and in spinal cord of asymptomatic and early symptomatic ALS-rodent model.

- Affymetrix Human Genome U133A Array (hgu133a)
Description
Invasive extravillous trophoblasts (EVTs) of the human placenta are critically involved in successful pregnancy outcome since they remodel the uterine spiral arteries to increase blood flow and oxygen delivery to the placenta and the developing fetus. To gain more insights into their biological role different primary cell culture models are commonly utilised. However, access to early placental tissue may be limited and primary trophoblasts rapidly cease proliferation in vitro impairing genetic manipulation. Hence, trophoblastic cell lines have been widely used as surrogates to study EVT function. Although the cell lines share some molecular marker expression with their primary counterpart, it is unknown to what extent they recapture the invasive phenotype of EVT. Therefore, we here report the first thorough GeneChip analyses of SGHPL-5, HTR-8/SVneo, BeWo, JEG-3 and the novel ACH-3P trophoblast cells in comparison to previously analysed primary villous cytrophoblasts and extravillous trophoblasts.

Description
We aimed to analyze the effects of Wnt-1 overexpression on the mRNA expression profile of human melanoma in a mouse xenograft model and correlated the results with then presence or absence of lymphangiogenesis and metastasis. Affymetrix gene expression analysis revealed activation of canonical and non-canonical targets genes in response to Wnt-1 as compared with controls. In regard to lymphangiogenic factors, the amount of VEGF-C was the single best marker to correlate with the amount of lymph-angiogenesis.
