Affymetrix Human Gene 1.0 ST Array (hugene10st)
Description
In this study gene expression profiles for 307 cases of advanced bladder cancers were compared to molecular phenotype at the tumor cell level. TUR-B tissue for RNA extraction was macrodissected from the close vicinity of the tissue sampled for immunohistochemistry to ensure high-quality sampling and to minimize the effects of intra-tumor heterogeneity. Despite excellent agreement between gene expression values and IHC-score at the single marker level, broad differences emerge when samples are clustered at the global mRNA versus tumor cell (IHC) levels. Classification at the different levels give different results in a systematic fashion, which implicates that analysis at both levels is required for optimal subtype-classification of bladder cancer.

Description
Dynamical response to oxygen downshift under fermentation conditions was tested by taking sample before (S1) and after (S2, S3 and S4) the oxygen downshift. The dynamical changes relevant for ongoing research on physiology were applied.

Description
We aimed to provide a molecular description of Lynch syndrome-associated urothelial cancer in relation to molecular subtypes of sporadic bladder cancer. Whole genome mRNA expression profiles of 41 tumors and immunohistochemical stainings against FGFR3, KRT5, CCNB1, RB1, and CDKN2A (p16) of 37 tumors from Lynch syndrome patients were generated. Pathological data, microsatellite instability, anatomic location, and overall survival data was analyzed and compared with data from sporadic bladder cancer.

- Affymetrix Zebrafish Genome Array (zebrafish)
Description
The role of ERbeta2 in zebrafish larvae was investigated by injection of a Morpholino against ERbeta2. After 72hpf, the morphants showed a strong disruption in their sensory systems. ERbeta2 has been shown to be needed for the normal functioning of the sensory system organs, the neuromasts. The mechanisms involved in the neuromast disruption in ERbeta2 morphants was identified by microarrays gene screening. After comparison of two screening with low and hign concentration of Morpholinos, genes that were present in the two microarrays screening were selected. The genes were then chosen by relevance for the mechanisms involved in the role of ERbeta2 in neuromast development. The ngn1 transcription factor, Notch3 and Notch1a showed to be up-regulated, also confirmed by in situ hybridization. The Notch signaling is known to be involved in cell fate in developing neuromasts. The overall conclusion is that ERbeta2 by interacting with the notch signaling pathways is critical for normal development of the neuromast of the lateral line in zebrafish.
