Effect of NPAP1/C15orf2 overexpression on transcriptome of HEK293 cells

ABSTRACT: 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

Effect of FTO overexpression and knockdown on transcriptome of HEK293 cells

Project 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. We used microarrays to investigate global gene expression changes depending on the level of FTO We compared FTO overexpressing and FTO depleted cells to cells with endogeneus level of FTO to determine global gene expression changes.

Expression profiles from HEK293 cells by overexpression of TRPM7 channel

Project description:The functional activity of TRPM7 is essential for cell viability and growth, and its expression is up-regulated in certain pathological conditions. In order to assess the effects of TRPM7 activity on cellular gene expression, inducible HEK293 cell-lines harboring the wild-type mouse TRPM7 and a mutant lacking the kinase domain were established. By using microarray analysis, we identified genetic profiles altered in transcription significantly and specifically by the expression of the functional TRPM7 channel. Overexpression of TRPM7 channel in HEK cells induce the cell damage and cell death. So we used tetracycline-inducible system for channel expression. However, since the treatment of inducer itself could also affect the transcription profile, we established another cell-line harboring a nonfunctional TRPM7 mutant (TRPM7DKD) as a control in which the entire kinase domain at the C-terminus was deleted. The wild-type and the non-functional TRPM7 channels were induced transiently, and the comparative changes in cellular transcription were investigated
