Summary : Since last years, the proteasome has emerged as a real and exciting target for anticancer therapy. Velcade
® (bortezomib, formerly known as PS341) remains the first selective proteasome inhibitor that has demonstrated significant preclinical activity in several tumor models and a significant efficacy in patients with refractory or relapsed multiple myeloma, resulting in an accelerated approval in US and Europe in such a setting. The major biological effect of bortezomib is the inhibition of the nuclear transcription factor NFκB, with subsequent inhibition of the growth tumor cells, induction of apoptosis, inhibition of angiogenesis and of cellular adhesion. The better understanding of the role of proteasome in the regulation of tumor cell growth has led to the development of new therapeutic approaches, notably in patients with multiple myeloma but also seems to hold interesting promises in other hematologic malignancies and solid tumors. This review provides a summary of the rationale for using proteasome inhibitors and an update on available and ongoing clinical studies involving human malignancies. |
