Strategies to enhance the immunogenicity of tumors are urgently needed. Although vaccination with irradiated dying lymphoma cells recruits a tumor-specific immune response, its efficiency as immunogen is poor. Annexin V (AxV) binds with high affinity to phosphatidylserine on the surface of apoptotic and necrotic cells and thereby impairs their uptake by(More)
Annexins constitute an evolutionary conserved multigene protein superfamily characterized by their ability to interact with biological membranes in a calcium dependent manner. They are expressed by all living organisms with the exception of certain unicellular organisms. The vertebrate annexin core is composed of four (eight in annexin A6) homologous(More)
Acquired resistance to apoptosis by tumor cells remains a major obstacle for cancer treatment, and hence the analysis of resistance to apo-ptosis constitutes a major goal in the development of antitumoral drugs. We have established a butyrate-resistant human colon adenocarcinoma cell line (BCS-TC2.BR2) from nontumorigenic BCS-TC2 cells to analyze whether(More)
