Protein degradation plays important roles in biological processes and is tightly regulated. Further, targeted proteolysis is an emerging research tool and therapeutic strategy. However, proteome-wide technologies to investigate the causes and consequences of protein degradation in biological systems are lacking. We developed "multiplexed proteome dynamics profiling" (mPDP), a mass-spectrometry-based approach combining dynamic-SILAC labeling with isobaric mass tagging for multiplexed analysis of ...[more]

Molecular Signature of response and potential pathways related to resistance to the HSP90 inhibitor, 17-AAG, in breast cancer.

Project description:We have done transcriptional profiling of 17-AAG treated (24h, 48H) breast cancer cell lines to understand the mechanisms of the drug action and indicate novel set of pharmacodynamic biomarkers of the drug response as well as of resistance Two-condition experiment, Untreated vs. Treated sensitive cells. Phenotype replicates: 8 untreated replicates, 14 treated replicates.

Aedes aegypti Aag-2 cells proteome modulation in response to Chikungunya virus infection

Project description:Chikungunya virus (CHIKV) is a single-stranded positive RNA virus that belongs to the genus Alphavirus and is transmitted to humans by infected Aedes aegypti and Aedes albopictus bites. In humans, CHIKV can cause painful symptoms during acute and chronic stages of infection. However, the virus-vector interaction has characteristics that allow a persistent infection, not disturbing the mosquito’s fitness. Here, we aimed to clarify aspects of CHIKV infection in Ae. aegypti Aag-2 cells through label-free quantitative proteomic analysis and transmission electron microscopy (TEM). We used MOI 0.1 to infect Aag-2 cells in biological triplicates over 48 h. TEM images show a high load of intracellular viral cargo at 48 hpi, as well as an elongated unusual mitochondria morphology that might indicate a mitochondrial imbalance. Moreover, a total of 196 Ae. aegypti protein groups were up or downregulated upon infection, related to protein synthesis, energy metabolism, signaling pathways and apoptosis. These regulated Aag-2 proteins might have roles in antiviral and/or in pro-viral mechanisms during CHIKV infection, to support the balance between viral propagation and the survival of host cell, leading to the persistent infection.

Native SEC-MS of the human HT29 colon adenocarcinoma cell line treated with the HSP90 inhibitor tanespimycin (17-AAG)

Project description:The molecular chaperone heat shock protein 90 (HSP90) works in concert with its co-chaperones to stabilize its client proteins, which include several drivers of oncogenesis and malignant progression. Pharmacologic inhibitors of HSP90 are proposed to trigger widespread remodeling of cellular protein complexes, including dissociation of co-chaperones from HSP90, disruption of client protein signaling networks, and recruitment of the protein ubiquitination and degradation machinery. However, proteomic studies to date have focused on inhibitor-induced changes in total protein levels, often overlooking protein complex alterations. Here, we use size-exclusion chromatography in combination with mass spectrometry (SEC-MS) to characterize the changes in native protein complexes following treatment with the HSP90 inhibitor 17-AAG in the human HT29 colon adenocarcinoma cell line.

Gene expression profile of CD4+ T-cells restimulated by anti-CD3 and anti-ICOS compared to anti-CD3 alone

Project description:Engagement of the ICOS receptor represents a key event in a process that culminates in Bcl6 expression and acquisition of the TFH and TFR phenotype. To better understand the essentials of ICOS-mediated signaling pathway, we profiled the changes in gene expression elicited after co-ligation of ICOS and CD3 compared with CD3 ligation alone. Naïve CD4+ T-cells were purified from single cell suspensions of B6 spleen and stimulated with anti-CD3 and anti-CD28 for 2d followed by resting overnight before 20 min of incubation with anti-CD3 and/or anti-ICOS and cross-linking with goat anti-hamster Ab for 8h. RNA was prepared, amplified, labeled and hybridized to Mouse Gene 1.0 ST Array (Affymetrix), in quadruplicates for anti-CD3 ligation and duplicates for anti-CD3/ anti-ICOS co-ligation.

Drug combination of 17-AAG and Belinostat on MDA-MB-231 breast cancer cells

Project description:Breast cancer is the most common cancer that threatens women's health. While the strategy of drug combination can help to reduce adverse effects and to overcome the resistance of clinical treatment of single drug. In this work, we report the synergetic effect between a HSP90 inhibitor 17-AAG and a HDAC inhibitor Belinostat, on the triple-negative breast cancer MDA-MB-231 cells. The RNA-Seq data analysis showed that the most over-represented KEGG pathways in the combination group came from migration or invasion related genes, which were not observed in the differentially expressed genes after the treatment of 17-AAG or Belinostat alone.

Transcription profiling of human peripheral blood monocytes from a patient with a heterozygous deletion of the CARMA1 gene cultured with anti-CD3, anti-CD3 and anti-CD28 or lipopolysaccharide

Project description:PBMCs were isolated from whole blood taken from one patient and one healthy control. Cells were cultured in media (RPMI) alone, with 1µg/ml anti-CD3, with 1µg/ml anti-CD3 & 1µg/ml anti-CD28 or with 0.5ng/ml LPS. Cells were harvested after 24 or 48 hours, RNA isolated using Trizol, purified using RNeasy columns and labelled using Illumina TotalPrep RNA Amplificiation kit (Applied Biosystems) before hybridisation to Illumina HumanRef-8 arrays.
