Nigrin b and ebulin l are type 2 ribosome-inactivating proteins (RIPs) with 10(4) times less cellular and in vivo toxicity than ricin that are currently being considered for the construction of anti-cancer conjugates. Here we provide evidence that both RIPs can be used for the construction of
Targeting tumour neovasculature using antibodies to the endothelial receptor CD105 (endoglin), is a potentially useful approach for anti-tumour therapy. We report on the preparation and the cytotoxicity of a novel immunotoxin consisting in the non-toxic type 2 ribosome-inactivating protein (RIP)
Ribosome-inactivating proteins (RIPs) are a family of enzymes that trigger the catalytic inactivation of ribosomes. The most known member of the family is the highly poisonous two-chain ricin isolated from Ricinus communis L. Sambucus species contain a number of two-chain RIPs structurally and
Aqueous extracts of mistletoe (Viscum album L.) contain toxic proteins (lectins) MLI (viscumin), MLII, and MLIII. We previously cloned the gene encoding MLIII precursor. In the present study, a gene fragment encoding the carbohydrate-binding subunit of mistletoe toxic lectin MLIII was cloned and
OBJECTIVE
Endoglin (ENG; CD105) is a co-receptor of the transforming growth factor-β (TGF-β) family that is highly expressed in proliferating endothelial cells. Often coopted by cancer cells, ENG can lead to neo-angiogenesis and vasculogenic mimicry in aggressive malignancies. It exists both as a
