Phthalate esters (PAEs)are by far the most widely used plasticisers and are categorized as high and low,depending on their molecular weight.Because of their extensive use,humans are most likely exposed to PAEs in the workplace and home environment through direct as well as indirect sources.Injection,inhalation,intravenous injection and skin absorption are potential pathways of expo-sure.With respect to health effects,phthalates are often classified as endocrine disruptors because of their ability to interfere with the endocrine syste m in the body.Furthermore,PAEs possess reproductive toxicity because of their influence on development of the reproductive system in infancy and development and differentiation of germ cells in adults.PAEs promote pathogenesis and development of liver cancer by activating peroxisome proliferator-activated receptor (PPAR)and DNA methylation.In addition, PAEs,which inhibit the i mmune functions of macrophages and pro mote hypersensitive response,pos-sess immunotoxicity.PAEs are also carcinogens that promote pathogenesis and development of cancers including breast,ovarian and so me other cancers.

Gastrointestinal stromal tumors are the common mesenchymal tumors of the gastrointestinal tract. The constitutive activation of KIT is one of the earlies ttransforming events in GISTs and occurs mainly through activating mutations in the kit gene. PDGFRa is associated with the pathogenesis of GISTs too. The main mutative site of KIT gene are exon11, exon9, exon13 and exon17 and those of PDGFRA are exon18, exon12 and exon14.The clinical parameter and the response to imatinib of GISTs are associated with the site and type of gene mutation. Imatinib mesylate is a small-molecule inhibitor that selectively inhibit the tyrosine kinase and the clinical use of it is one milestone of the targeted therapy of GISTs. We review the gene mutation and targeted therapy development of gastrointestinal stromal tumors in this article.
