Antitumor effect of B16 melanoma cells genetically modified with the angiogenesis inhibitor rnasin.
The growth of new blood vessels is an essential condition for the development of tumors with a diameter greater than 1-2 mm and also for their metastatic dissemination. RNasin, the placental ribonuclease inhibitor, is known to have antiangiogenic activity through the inhibition of angiogenin and basic fibroblast growth factor. Nevertheless, the administration of the recombinant form of a protein poses several limitations; as a result, we have studied the antitumor effect of RNasin in a murine gene therapy model. RNasin cDNA was subcloned into the pcDNA3 expression vector, and the resulting recombinant plasmid was used to transfect the B16 murine melanoma cell line. An RNasin inverted constr…

Peptides in apoptosis research
Apoptosis is a complex process that plays a central role in physiological and pathological cell death. This fast evolving research area has experienced incredible development in the past few years. Progress in the knowledge of the structure of many of the main molecular actors of the apoptotic signal transduction pathways has driven the design of synthetic peptides that in some cases can function as simplified versions of their parent proteins. These molecules are contributing to a better understanding of the activity and regulation of apoptotic proteins and also are setting the basis for the discovery of effective drugs to combat important diseases related to apoptosis. Most applications o…
