Project description:In order to discover critical pathways /networks or therapeutic targets in pleural mesothelioma we profiled 55 tumors along with paired normal tissue (for 41 tumors) using Affymetrix U133 plus 2.0 chips RNA isolated from frozen resected tumor and normal tissues was hybridized to Affymetrix U133 plus 2.0 chips to discover genes upregulated/downregulated in mesothelioma tumors compared to paired normal non-tumor adjacent tissue as well as find differences between the different tumors
Project description:We screened pleural effusion proteomes of mesothelioma and lung adenocarcinoma patients to identify novel soluble mesothelioma biomarkers. We performed quantitative mass spectrometry-(MS-) based proteomics using isobaric tags for relative and absolute quantification (iTRAQ) and used narrow range immobilized pH gradient/high resolution isoelectric focusing (IPG/HiRIEF; pH 4 to 4.25) prior to analysis by nano liquid chromatography-coupled MS/MS. Pleural effusions from patients with malignant mesothelioma (n=6), lung adenocarcinoma (n=6), or benign mesotheliosis (n=7) were analyzed, and more than 1,300 proteins were identified.

Project description:Regional delivery of oncolytic viruses has been shown to promote immune responses. Malignant pleural effusions comprise an immunosuppressive microenvironment, and the ability of oncolytic viruses to generate immune responses following regional delivery in patients with malignant pleural effusions is unknown. We conducted a phase I clinical trial that studied the intrapleural administration of oncolytic vaccinia virus to establish the safety and feasibility in patients with malignant pleural effusion due to malignant pleural mesothelioma or metastatic disease. In patients with malignant pleural mesothelioma, by correlative analysis of pre- and post-treatment tumor biopsies, we provide insight into tumor-specific viral uptake and associated immune responses.
Project description:For establishing a live-cell biobank of Malignant Pleural Mesothelioma (MPM) samples, cultures of two MPM patients were compared to the original tumor tissue using Affymetrix OncoScan Microarrays for genome-wide CNV and LOH detection.
