Graft versus-host disease (GVHD) severely limits the application of allogeneic hematopoietic stem cell transplantation (allo-HSCT) in treating leukemia. Dendritic cells (DCs) are critical for the development. Here, we examined the effect of proteasome inhibitor Bortezomib on DCs in vitro. Primary cultured mouse DCs were treated with Bortezomib and their proliferation was observed. The expressio...
Purpose: Searching for novel strategies to modulate apoptosis in neuroblastoma, we investigated the potential of the proteasome inhibitor bortezomib. Experimental Design: The effect of bortezomib on TRAIL (TNF-related apoptosis-inducing ligand)induced apoptosis signaling pathways was analyzed in neuroblastoma cell lines, primary neuroblastoma cultures, and in an in vivo model. Results: Bortezom...
The proteasome inhibitor bortezomib is a new targeted treatment option for refractory or relapsed acute lymphoblastic leukemia (ALL) patients. However, a limited efficacy of bortezomib alone has been reported. A terminal pro-apoptotic endoplasmic reticulum (ER) stress/unfolded protein response (UPR) is one of the several mechanisms of bortezomib-induced apoptosis. Recently, it has been document...
BACKGROUND In vitro depletion of alloreactive T cells using the proteasome inhibitor bortezomib is a promising approach to prevent graft-versus-host disease after allogeneic stem cell transplantation. We have previously described the ability of bortezomib to selectively eliminate alloreactive T cells in a mixed leukocyte culture, preserving non-activated T cells. Due to the role of regulatory T...
Despite advances in the treatment of T‑cell acute lymphoblastic leukemia (T‑ALL), the outcome of T‑ALL treatment remains unsatisfactory, therefore, more effective treatment is urgently required. The present study examined the cytotoxicities of bortezomib in combination with daunorubicin against human Jurkat and Molt‑4 T‑ALL cells and primary T‑ALL cells. Compared with treatment alone, co‑exposu...
The cellular and molecular effects of the proteasome inhibitor bortezomib on breast cancer cells are as yet poorly characterized. Here, in a panel of six breast cancer cell lines, bortezomib reduced viability in a concentration-dependent, time-dependent, and cell line-dependent manner. Proteasome activity was relatively high in two of the three more resistant cell lines. No relationship was obs...
Bortezomib is a proteasome inhibitor with proven efficacy in multiple myeloma and non-Hodgkin's lymphoma. This study reports the effects of bortezomib in B-cell lymphoma cell lines with differing sensitivity to bortezomib to investigate factors that influence sensitivity. Bortezomib induced a time- and concentration-dependent reduction in cell viability in five lymphoma cell lines, with EC(50) ...
Bortezomib (Velcal) was the first proteasome inhibitor to be approved by the US Food and Drug Administration to treat patients with relapsed/refractory multiple myelomas. Previous studies have demonstrated that bortezomib inhibits tumor cell proliferation and induces apoptosis by blocking the nuclear factor (NF)-κB pathway. However, the exact mechanism by which bortezomib induces cancer cell ap...
PURPOSE Single-agent chemotherapy is largely the treatment of choice for systemic therapy of metastatic melanoma, but survival rates are low, and novel adjuvant and systemic therapies are urgently required. Endoplasmic reticulum (ER) stress is a potential therapeutic target, and two relatively new drugs, fenretinide and bortezomib (Velcade), each acting via different cellular mechanisms, induce...
IMPORTANCE Spontaneous reports to the National Registry of Drug-Induced Ocular Side Effects and case reports in the literature suggest an association between bortezomib use and chalazia. OBSERVATIONS To our knowledge, there have been 24 reports of bortezomib-associated chalazia. Fourteen reports were collected from the National Registry of Drug-Induced Ocular Side Effects. These reports origi...
