To exploit overexpression of erbB2 in human cancers, we constructed a single-chain immunotoxin (erb-38) that contains the Fv portion of monoclonal antibody e23 fused to a truncated form of Pseudomonas exotoxin A. In a Phase I study, five breast cancer patients and one esophageal cancer patient received three doses of erb-38 at 1.0 and 2.0 microg/kg.(More)
Colorectal cancer (CRC) displays a predilection for metastasis to liver. Although stromal cell-derived factor-1 (SDF-1)/CXCR4 plays an important role in the liver metastasis, the molecular mechanism still remains obscure. We previously reported that integrin αvβ6 was implicated in the progression of CRC. However, no data are currently available on the cross(More)
We previously reported that β6 integrin played an important role in the progression of colon cancer. In this study, we demonstrated that β6 integrin induced the expression of MMP-3/MMP-9 and the invasion of colon cancer cells. Moreover, that function was abolished by the inhibition of ERK/MAPK pathways or knockdown of ETS1, an important transcription factor(More)
Colorectal cancer (CRC), which is notorious for high morbidity and mortality around the world, shows a predilection for metastasis to liver. Interleukin-8 (IL-8), a chemokine with a defining CXC amino acid motif, has been reported to promote CRC cell migration and is associated with poor prognosis of CRC. However, the underlying molecular mechanism of(More)
Transvaginal cholecystectomy has been performed successfully at several research institutions worldwide using natural orifice transluminal endoscopic surgery (NOTES) techniques. However, it is a growing new surgical concept in China. Several technical challenges hinder the safe clinical application of NOTES. This study investigated transvaginal endoscopic(More)
Both transcriptional factor Ets-1 and integrin αvβ6 play an important role in the development and progression of cancer. The aim of our study was to investigate the expression of Integrin αvβ6 and Ets-1, two proteins’ correlation and their clinical significance in colorectal cancerous tissues. The specimens were arranged into microarray using the(More)
Hypoxia-inducible-1α (HIF-1α) expression was intimately correlated with apoptosis and proliferation of cancer cells. However, conclusions of different studies on the effects of HIF-1α expression on cell apoptosis and cell proliferation of hepatoma cells remain controversial. In view of the current status, we reassess(More)
PURPOSE Adjuvant chemotherapy is one of the significant treatments for colon cancer in clinic. However, it does not achieve the desired therapeutic efficacy, largely due to chemotherapeutic resistance. Integrinβ6 (ITGB6) is expressed in malignant colonic epithelia, but not in normal epithelia, and is associated with the progression, metastasis, and(More)
Gliomas are the most common and lethal primary tumors of the central nervous system (CNS). Despite current rigorous treatment protocols, effect of chemotherapy has failed to improve patient outcome significantly. Curcumin is a potent antioxidant that possesses both anti-inflammatory and anti-tumor activities, can suppress the initiation, promotion, and(More)
Norcantharidin has been used as an efficacious anticancer drug in China for many years, but its true mechanism remains poorly understood. Intriguingly, in an in vitro series study of anticancer drugs, we found that norcantharidin can effectively inhibit epithelial tumor cells from expressing integrin alphavbeta6. Our previous studies have confirmed that(More)
