We recently reported that anti-inflammatory macrophages contribute to the initiation of colorectal carcinogenesis in IBD patients by inducing epithelial-mesenchymal-transition associated alterations in colonic epithelial cells. In this process, TGFβ1 dependent upregulation of the adhesion molecule L1CAM is one key event, paving the way to colitis associated tumorigenesis and metastatic spread.
We have determined the tumor-initiating activity of (+/-)syn- and (+/-)anti-7,12-dimethylbenz[a]anthracene-3,4-diol-1,2-epoxide (syn- and anti-DMBADE), the two metabolically formed bay-region diol epoxides of DMBA, and we have also analyzed mutations in the H-ras gene from tumors induced by these compounds. Using a two-stage, initiation-promotion protocol for tumorigenesis in mouse skin, we hav...
Emerging evidence suggests that the Notch/Delta-like ligand 4 (Dll4) pathway may offer important new targets for antiangiogenesis approaches. In this study, we investigated the clinical and biological significance of Dll4 in ovarian cancer. Dll4 was overexpressed in 72% of tumors examined in which it was an independent predictor of poor survival. Patients with tumors responding to anti-VEGF the...
Despite recent advances in the management of a wide variety of solid tumors, the outcomes for patients with metastatic urothelial carcinoma (MUC) remain extremely poor. Cisplatin-based combination chemotherapy remains the standard of care for first-line systemic treatment of MUC, and for more than 20 years there have been no other US Food and Drug Administration-approved treatment options avail...
Systemic chemotherapy has become the cornerstone of therapy for retinoblastoma. The advent of novel chemotherapeutic and antiangiogenesis agents together with new routes of drug administration including periocular, intravitreal and intra-ophthalmic artery injection will hopefully revolutionize the management of this sight-threatening and potentially fatal infantile ocular neoplasm.
The chick embryo chorioallantoic membrane (CAM) is commonly used as an experimental in vivo assay to study both angiogenesis and antiangiogenesis in response to tissues, cells or soluble factors. This article summarizes literature data about the use of the CAM in the study of tumor angiogenesis and particularly our experimental data concerning the study of angiogenesis in multiple myeloma and i...
The pleiotropic effects of resveratrol include anti-inflammatory, antioxidant, and anticancer activities, and thus unique possibilities exist to explore mechanistic pathways of chemoprevention. The aim of this study was to investigate the role of microRNA (miRNA) alterations induced by resveratrol in the context of chemopreventive mechanisms against dextran sodium sulfate (DSS)-induced colitis-...
