Expression data from human sarcoma patient samples treated with either vehicle control or Nutlin-3a

Project description:This study has examined the molecular mechanisms underlying sensitivity of sarcomas to Nutlin-3a, a non-genotoxic activator of the p53 pathway. Human patient material was collected immediately following surgical resection, dissected into small pieces and ex planted onto gelatin sponges immersed in media containing either vehicle control or Nutlin-3a (10uM and/or 50uM) for 48 hours. Nutlin-3a represents a novel targeted therapy for the treatment of sarcomas. We have examined expression profiles of genes upregulated in sarcoma patient derived tissues following nutlin-3a treatment ex vivo 16 samples ((Vehicle control and Nutlin-3a (10uM and 50uM) treated samples)) from 6 sarcoma patients

Human BJ fibroblasts containing control vs. BRD7 shRNA

Project description:Transcriptional profiling of human BJ fibroblasts comparing control FF shRNA expressing cells vs. BRD7 shRNA expressing cells under two conditions, either untreated or treated with 8uM nutln-3a for 8 hours. This experiment was done using two independent shRNAs targeting BRD7. Nutlin-3a was used to stabilize p53 and induce its transcriptional activity. Two-condition experiment, FF shRNA cells vs. BRD7 shRNAs cells in two experimental conditions, either untreated or treated with nutlin-3a.

Interruption of p53-MDM2 Interaction by Nutlin-3a in Human Lymphoma Cell Models Initiates a Cell-Dependent Global Effect on Transcriptome and Proteome Level

Project description:In most lymphomas, p53 signaling pathway is inactivated by various mechanisms independent to p53 gene mutations or deletions. In many cases, p53 function is largely regulated by alterations in the protein abundance levels by the action of E3 ubiquitin-protein ligase MDM2, targeting p53 to proteasome-mediated degradation. In the present study, an integrating transcriptomics and pro-teomics analysis was employed to investigate the effect of p53 activation by a small-molecule MDM2-antagonist, nutlin 3a, on three lymphoma cell models following p53 activation. Our analy-sis revealed a system-wide nutlin 3a-associated effect in all examined lymphoma types, identifying in total of 4037 differentially affected proteins involved in a plethora of pathways, with significant heterogeneity among lymphomas. Our findings include known p53-targets and novel p53 activa-tion effects, involving transcription, translation, or degradation of protein components of path-ways, such as a decrease in key members of PI3K/mTOR pathway, heat-shock response, and gly-colysis, and an increase in key members of oxidative phoshosphorylation, autophagy and mito-chondrial translation. Combined inhibition of HSP90 or PI3K/mTOR pathway with nutlin 3a-mediated p53-activation enhanced the apoptotic effects suggesting a promising strategy against human lymphomas. Integrated omic profiling after p53 activation offered novel insights on the regulatory role specific proteins and pathways may have in lymphomagenesis.

Pharmacological inhibition of WIP1 sensitizes acute myeloid leukemia cells to MDM2 inhibitor Nutlin-3a

Project description:The wild-type p53-inducible protein phosphatase WIP1, encoded by the PPM1D gene, is a negative regulator of p53 and is involved in cell cycle control and DNA damage stress-response. In acute myeloid leukemia (AML), the restoration of p53 activity through MDM2 inhibition proved efficacy in a number of combination strategies. We investigated the therapeutic potential of its inhibition through the selective WIP1 inhibitor (WIP1i) GSK2830371, in association with the MDM2 inhibitor Nutlin-3a (Nut-3a) in a panel of AML cell lines and performed gene expression analysis of single agent and combined treatments. A p53-related signature was significantly upregulated in the TP53-wildtype MV-4-11 AML cell line. Moreover, drug-specific transcriptional changes likely contribute to the synergistic combination effect.

Transcriptomics analysis in 3T3L1 preadipocytes with activation of p53 via Nutlin-3a treatment

Project description:3T3L1 preadipocytes were treated with DMSO control and Nutlin-3a (prepared in DMSO) and total RNA extracted from the treated cells were subjected to illumina based RNA-seq to analyze and compare transcriptome to understand gene expression regulation influenced by p53 activation via Nutlin-3a treatment.
