Project description:Transcriptional profiling of CHO-K1 cells comparing to in-house serum-free and suspension adapted CHO-K1 cells in the exponential phase. Goal was to determine the effects of serum on CHO-K1 cells.
Project description:CHO-K1 (wildtype) and CHO-K6 (stablely overexpressing human HER2) cells were terated with 10 ug/ml transtuzumab or pertuzumab and their combination for 24 h and then the whole gene expression was analyzed by cDNA array.
Project description:Transcriptional profiling and gene expression profiling analysis of sorted CD8+IL-10+ T cells compared to CD8+IL-10- T cells using IL-10-GFP(tiger) reporter mice Two sample, CD8+IL-10+ T cells vs CD8+IL-10- T cells. Three replicate per array.
Project description:CHO cells grown in serum-free medium have an absolute requirement for putrescine supplementation due to their deficiency in activity of the enzyme arginase. Consequently, principally in this system, polyamines play a central but poorly-understood role in cell proliferation Cell growth arrest, mainly in the S- and G2/M phases was observed. We used differential gene expression data to investigate the impact of polyamine deprivation on the transcriptome of CHO cells
Project description:Chinese hamster ovary cells (CHO) were exposed to highly concentrated feed solution during a fed-batch cultivation which causes an unphysiological osmolality increase (>300 mOsm/kg) affecting cell physiology, morphology and proteome. To get a deeper insight into underlying molecular mechanisms involved in cellular hyperosmolality response, we performed a comparative quantitative label-free proteome study of hyperosmolality-exposed vs. control CHO cells by nanoLC-ESI-MS measurement approach (orbitrap-MS). Our observations correlate well with the data from recent CHO-based fluxome and transcriptome studies and expose hitherto unknown targets involved in response to hyperosmotic pressure in mammalian cells.
