OBJECTIVE Eriocalyxin B (EriB) is a natural diterpenoid purified from Isodon eriocalyx var. laxiflora and possesses strong antileukemic activity. In this study, we further investigated its effect and mechanism of action in human lymphoma. MATERIALS AND METHODS In vitro, a series of B- and T-lymphoma cells were treated with EriB. Cell apoptosis was(More)
Vascular endothelial growth factor-A, an angiogenesis stimulator expressed on both tumor endothelial and malignant T cells, is involved in tumor progression in T-leukemia/lymphoma. Here, we assessed the impact of therapeutic vascular endothelial growth factor-A blockade on tumor-endothelial cell interaction and on tumor progression. In a murine xenograft(More)
Mantle cell lymphoma (MCL) is a rare and aggressive type of B-cell non-Hodgkin's lymphoma. Patients become progressively refractory to conventional chemotherapy, and their prognosis is poor. However, a 38% remission rate has been recently reported in refractory MCL treated with temsirolimus, a mTOR inhibitor.Here we had the opportunity to study a case of(More)
Endothelial cells have special relevance in tumor progression. Here, we investigated the effect of the proteasome inhibitor bortezomib on tumor–endothelial cell interaction in T-cell leukemia/lymphoma. In vitro, T-leukemia/lymphoma cell lines and primary T-leukemia/lymphoma cells were cultured with endothelial cells, either together or separately in(More)
