A novel therapeutic strategy targeting the mesenchymal phenotype of malignant pleural mesothelioma by suppressing LSD1 [array]

Project description:Transcriptome analysis following knock down of LSD1 in ACC-MESO-1 cells. Malignant pleural mesothelioma (MPM) is a highly aggressive tumor that has a low overall survival; however, no significant treatment advances have been made in the past 15 years. In this study we investigated whether targeting lysine-specific demethylase 1 (LSD1/KDM1), a histone-modifying enzyme responsible for demethylating histone H3 lysine 4 and lysine 9, could represent a novel therapeutic strategy for patients with MPM. We found that suppressing LSD1 induces an epithelial phenotype in sarcomatoid MPM cells, while attenuating the mesenchymal phenotype sensitized MPM cells to cisplatin-induced apoptosis through the FAK pathway. To investigate the potential mechanisms underlying FAK pathway activation, we performed transcriptome analysis using two different shRNA constructs against the LSD1.

Identification of novel markers for malignant pleural mesothelioma diagnosis

Project description:Diagnosis of malignant pleural mesothelioma (MPM) is difficult, the most common differential diagnosis being benign pleural diseases and metastatic adenocarcinomas. In order to identify novel markers able to improve diagnostic accuracy, we performed a genome-wide gene expression analysis on tumor cells lines established from pleural effusions (13 MPM and 4 lung adenocarcinoma). Our microarray analysis led to the identification of genes encoding novel cellular and soluble markers whose expression was validated by RT-qPCR. Immunohistochemical staining of tumor biopsies with anti-type-III collagen antibodies were positive in mesothelioma cells but not in adenocarcinoma cells. Using ELISA, we showed that the C-C motif chemokine 2 (CCL2) concentration was significantly higher in pleural effusions from patients with mesothelioma (n = 61) than in subjects with adenocarcinoma (n = 25) or with benign pleural effusions (n = 15): median (interquartile range) = 2.99 ng/mL (1.76-6.01) versus 0.99 ng/mL (0.51-1.83) and 1.47 ng/mL (0.80-1.56), respectively, P < 0.0001. Conversely, the galectin-3 concentration was lower in mesothelioma: 11.50 ng/mL (6.73-23.53) versus 24.74 ng/mL (20.42-70.35) and 17.64 ng/mL (14.81-24.68), respectively, P < 0.0001. The AUC for CCL2 were 0.8030 and 0.7716 for differentiating mesothelioma from adenocarcinoma or benign effusions, respectively. Similarly, the AUC obtained for galectin-3 were 0.7980 and 0.6923, respectively. In conclusion, type-III collagen, CCL2 and galectin-3 are promising new diagnostic markers for mesothelioma.

Chromosomal aberration of malignant pleural mesothelioma cell lines

Project description:To identify regions that display DNA copy number alterations in malignant pleural mesothelioma (MPM), we carried out array comparative genomic hybridization (CGH) analysis with 14 MPM cell lines. Regions of genomic aberrations observed in >20% of individuals were 9p21.3, 13q12.11, 16p13, and 22q12.2 of losses. The most frequent alteration was 9p21.3, which include the p16INK4/p14ARF. The loss of 22q12.2 regions include the NF2 was observed in 3 out of 14 cell lines. In 3 cell lines, loss of 13q12.11 region which contains Large Tumor Suppressor, homolog 2 (LATS2) was detected. Human malignant pleural mesothelioma cell lines were profiled on Agilent 244K aCGH arrays according to manufacturer’s instructions. Pooled normal human genomic DNA was used as the reference.
