Receptor tyrosine kinase MET (c-MET) has received considerable attention as a potential target for gastric cancer (GC) therapy and a number of c-MET inhibitors have been developed. For successful drug development, proper preclinical studies especially using patient derived cancer cell lines are very important. We profiled MET and MET-related characteristics in 49 GC cell lines to utilize them as models in preclinical studies of GC. Forty-nine cell lines were analyzed for genetic, biological, and molecular status to characterize MET and MET-related molecules...

RATIONALE: Mesenchymal-to-epithelial transition (MET) exon 14 skipping mutation was a targetable alteration in nonsmall-cell lung cancer (NSCLC), and the MET inhibitor of crizotinib had the most efficacy among all the targeted drugs. Most of the cancer-related deaths are associated with metastasis. Circulating tumor cells (CTCs) have been a valuable biomarker in assessing metastasis. Recent experiences suggested that CTCs detection may help improve diagnosis and predict prognosis for patients with NSCLC...

Deficiency of the mitochondrial enzyme succinyl COA ligase (SUCL) is associated with encephalomyopathic mtDNA depletion syndrome and methylmalonic aciduria. This disorder is caused by mutations in both SUCL subunits genes: SUCLG1 (α subnit) and SUCLA2 (β subnit). We report here, two Tunisian patients belonging to a consanguineous family with mitochondrial encephalomyopathy, hearing loss, lactic acidosis, hypotonia, psychomotor retardation and methylmalonic aciduria. Mutational analysis of SUCLG1 gene showed, for the first time, the presence of c...

MET encodes a receptor tyrosine kinase c-MET for hepatocyte growth factor (HGF). The specific combination of c-MET and HGF activates downstream signaling pathways to trigger cell migration, proliferation, and angiogenesis. MET exon 14 alterations and MET gene amplification play a critical role in the origin of cancer. Several monoclonal antibodies and small-molecule inhibitors of c-MET have been evaluated in clinical trials. In patients with advanced non-small cell lung cancer, cabozantinib and crizotinib showed clear efficacy with a generally tolerable adverse events profile...

INTRODUCTION: Targeted therapies such as tyrosine kinase inhibitors (TKIs) have dramatically improved the treatment of lung adenocarcinoma, and detection of activating mutations of genes such as EGFR or anaplastic lymphoma kinase gene (ALK) is now mandatory in the clinical setting. However, additional targetable alterations are continuously being described and forcing us to adapt our detection methods. Here we have evaluated the ability of eight amplicon-based next-generation sequencing (NGS) panels to detect the recently described mesenchymal epithelial transition factor (MET) exon 14 (METex14) alterations or new mutations conferring resistance to TKIs...
