Recent experimental evidence suggested that the synthetic peptide desmopressin (DDAVP) interferes tumor angiogenesis by inducing the formation of angiostatin. It is also known that DDAVP stimulates the endothelial release of von Willebrand factor, a key element in resistance to metastasis. Vasopressin V2 receptor agonists such as DDAVP seem to evoke dual angiostatic and antimetastatic effects, ...

aceae) is frequently used in Asian countries as a traditional medicine. The major components of ginseng are ginsenosides. These ginsenosides have been reported to show various biological activities including antiinflammatory activity and antitumor effects. The pharmacological actions of these ginsenosides have been explained by the biotransformation of ginsenosides by human intestinal bacteria....

It has recently been demonstrated that in vivo administration of murine interleukin 12 (IL-12) to mice results in augmentation of cytotoxic natural killer (NK)/lymphocyte-activated killer cell activity, enhancement of cytolytic T cell generation, and induction of interferon gamma secretion. In this study, the in vivo activity of murine IL-12 against a number of murine tumors has been evaluated....

The role of some RNases as antitumoral agents has been recently emphasized. We have previously demonstrated a striking inhibitory effect of bovine seminal RNase on the in vitro growth of tumor cells of metastatic origin. This has prompted us to test the effects of this protein in vivo on the induction of metastatic foci in mice lungs after i.m. injection of a highly metastatic Lewis lung carcin...

The role of BRCA1 in breast cancer metastasis is a less explored area that might have importance in increased aggressiveness of BRCA1 defective triple negative cancers. The possible influence of BRCA1 on apico basal polarity and ezrin, radixin and meosin (ERM) proteins are discussed in this review as a reason for cell metastasis. This might help in developing antimetastatic drugs that could hel...
