Affymetrix Human Genome U133 Plus 2.0 Array (hgu133plus2)
Description
Cutaneous squamous cell carcinoma (cSCC) is one of the most common malignancies in fair skinned populations worldwide and its incidence is increasing. Despite previous observations of multiple genetic abnormalities in cSCC, the oncogenic process remains elusive. The purpose of this study was to investigate the transcriptomes of cSCC and actinic keratoses (AK), to elucidate key differences between precursor AK lesions and invasive carcinoma.

Description
To gain insight into the function of Nuclear pore associated protein 1 (NPAP1, formerly C15orf2), we overexpressed NPAP1 in HEK293 cells. We detected no significant difference between NPAP1-expression of induced and uninduced cells in three technical replicates, exept for an approximately 10-fold increase in the NPAP1 transcript itself. This indicates that overexpression of NPAP1 does not change mRNA expression profiles of HEK293 cells. We used microarrays to investigate global gene expression changes depending on the level of NPAP1/C15orf2
Publication Title
The imprinted NPAP1/C15orf2 gene in the Prader-Willi syndrome region encodes a nuclear pore complex associated protein.

Description
To gain insight into FTO function, we knocked down and overexpressed FTO in HEK293 cells.Genetrail analyses of expression profiles pointed to the RNA splicing and processing machinery. Intriguingly, using immunocytochemistry and confocal laser scanning microscopy, we observed strong enrichment of FTO in nuclear speckles and - to a lesser extent - in nucleoli, but not in other known nuclear bodies. We also studied RNA samples of Fto knockout and wild type mice with regard to content of methylated and unmethylated nucleosidesand observed that ratios of modified and unmodified uracil and adenine were different depending on the presence of FTO. Taken together, our data suggest that FTO is involved in RNA processing and modification.

Description
The goal of this experiment was to investigate the molecular mechanism of how Set-beta regulates neurite growth. Set-betas subcellular localization is regulated by posttranslational modifications. We found that Set-beta suppresses neurite growth of purified postnatal rat retinal ganglion cell (RGC) primary neurons when it is overexpressed in the nucleus, whereas recruiting Set-beta to cellular membrane by fusing myr-tag to its N-terminus promotes neurite growth. Here, we transfected purified by immunopanning postnatal rat RGC with wild-type Set-beta which localizes to the nucleus, myr-Set-beta which is recruited to cellular membranes, and mCherry control, and analyzed with microarrays Set-betas subcellular localization-dependent effects on gene expression. We found that wild-type Set- regulated expression of significantly more genes than myr-Set-, consistent with wild-type Set-s nuclear localization and previously described roles in regulating transcription. These data reveal potential downstream gene effectors regulating neurite growth, and specific candidate genes could be validated and tested in future experiments.
