Project description:Microarray based mRNA profiling was used to identify the mechanism of action for the small molecule VLX60. MCF7 cells were treated with the drug candidate VLX60 for 6h prior to RNA isolation
Project description:Primary cultures of patient tumor cells (PCPTC) were used in a cell-based cytotoxicity screen. Microarray-based mRNA profiling was used to identify the mechanism-of-action for the small molecule VLX 50.
Project description:Microarray based mRNA profiling was used to identify the mechanism of action for the small molecule b-AP15. MCF7 cells were treated with b-AP15 (1µM) or vehicle for 6 hours, followed by RNA isolation and gene expression analysis.
Project description:Primary cultures of patient tumor cells (PCPTC) were used in a cell-based cytotoxicity screen. Microarray-based mRNA profiling was used to identify the mechanism-of-action for the small molecule VLX 50. MCF7 cells were treated with the PCPTC screening hit VLX 50 or DMSO control for 6h prior to RNA isolation. One sample per treatment. Data were analyzed using both MAS5.0 and RMA.
Project description:A phenotypic cell-based high-throughput screen identified a novel small molecule, CCI-006 with selective cytotoxic activity against MLL-rearranged leukaemia cell lines. The aim of this experiment was to identify the mechanism of action of CCI-006 by investigating the gene expression changes induced in a MLL-rearranged leukaemia cell line following a short incubation with the compound.
Project description:Microarray based mRNA profiling was used to charactarize the response to the compound VLX600 in cells grown as spheroids. Cells used was colon cancer cells HCT116 and HCT116HIF1a knock-out. We identify the small molecule VLX600 as a drug that is preferentially active against quiescent cells in colon cancer 3-D microtissues. The anticancer activity is associated with reduced mitochondrial respiration, leading to a bioenergetic catastrophe and tumor cell death. VLX600 shows enhanced cytotoxic activity under conditions of nutrient starvation. Microarray based mRNA profiling was used to charactarize the response to the compound VLX600 in cells grown as spheroids. Cells used was colon cancer cells HCT116 and HCT116HIF1a knock-out cells.
Project description:SPC2996 is a novel locked nucleic acid (LNA) phosphorothioate antisense molecule targeting the mRNA of the Bcl-2 oncoprotein. We investigated the mechanism of action of SPC2996 and the basis for its clinically observed immunostimulatory effects in chronic lymphocytic leukemia (CLL). Patients with relapsed CLL were treated with a maximum of six doses of SPC2996 (0.2-6mg/ kg) in a multicenter phase I trial. Microarray-based transcriptional profiling of circulating CLL cells was carried out before and after the first infusion of SPC2996 in eighteen patients. We used microarrays to characterize global gene expression changes of circulating CLL cells in response to SPC2996 infusion in 18 patients Key word : Response to therapeutic agent We performed microarray-based gene expression profiling in serial peripheral blood samples from 18 individual CLL patients before and after treatment with SPC2996
