Abstract   Hypoxia is known as an important trigger for the development of metastases in human cancers. Heat shock proteins (Hsps) are up-regulated by cellular stressors including hypoxia. To date, the functional role of Hsps within the hypoxic tumor microenvironment for esophageal squamous cell cancer (ESCC) remains poorly defined. Methods CoCl₂ was used to induce hypoxia in cultured ESCC cells which was confirmed by 2′,7′ –dichlorofluorescin diacetate (DCFDA) assay. 7-Dimethylaminoethylamino-17-demethoxygeldanamycin (17-DMAG), a selective Hsp90 inhibitor, was used to treat 2 ESCC cell lines, KYSE-170 and -510 cells pretreated with or without CoCl₂₂₂₂₂ in different concentrations, followed by cytotoxicity (MTT) and migration assays. In parallel, expression of Hsp90, vascular endothelial growth factor (VEGF), hypoxia-inducible factor-1α (HIF-1α), and markers related to epithelial-mesenchymal transition (EMT) such as snail/E-cadherin, by immunoblot or ELISA while analyzing cell proliferation and migration of treated ESCC cells. Results CoCl₂ induced hypoxia was supported by induction of reactive oxygen species (ROS). CoCl₂ (200 μM) significantly suppressed cell viability and proliferation with a concomitant up-regulation of VEGF and HIF-1α in a dose-dependent fashion. In contrast, cell migration was significantly increased in response to CoCl₂ while down-regulating E-cadherin with a concomitant increase in Snail expression. 17-DMAG decreased expression of VEGF and HIF-1α while inhibiting cell migration and invasion. Conclusion Our data demonstrate that CoCl2 induced hypoxia promotes EMT and angiogensis, which are inhibited by 17-DMAG. These results suggest that hypoxia induced EMT and angiogensis is Hsp90 dependent in ESCC.

Abstract Background Endoscopic resection is the treatment of choice for early esophageal cancers. However, resections comprising more than 70–80 % of the circumference are associated with a high risk of stricture formation. Currently, repetitive local injections and/or systemic steroids are given for prevention. Case report We present here the case of a 78-year-old male patient who had a near circumferential endoscopic submucosal dissection for a pT1a mm, L0, V0, R0, G2 esophageal squamous cell cancer. At the end of endoscopic resection, 80 mg of triamcinolone was injected locally. The patient was then treated with oro-dispersible budesonide tablets (2 × 1 mg/day) and nystatin (4 × 100 000 I.E.) for 8 weeks. This treatment resulted in complete healing without any stricture formation and did not result in any complications. Discussion Treatment with orodispersible budesonide tablets could help prevent strictures after large endoscopic resections in the esophagus.
