Nympho A glial-specific, repressible, adenovirus vector for brain tumor gene therapy. CA Cancer J Clin. Vasculogenic mimicry, a process by which cancer cells can adopt the functionality of endothelial cells, has been characterized in human melanoma cells showing their intrinsic plasticity and potential capacity for tight interaction with neighbor endothelium

However, this previous work did not provide evidence about the efficacy of the approach on the complete set of animals, the extent of the in vivo growth inhibition, and the potential tumorigenic capacity of the pluripotent bone stromal cells that contributed a bone component to the chimeric tumors. The corresponding groups received i. Secreted protein acidic and rich in cysteine SPARC is a secreted protein involved in cell-extracellular matrix interactions Filipino Tagalog.

The expression of the secreted protein acidic and rich in cysteine SPARC is associated with the neoplastic progression of human melanoma. Figure 4. SPARC expression in primary human renal cell carcinoma: We have shown that expression of the herpes simplex virus- thymidine kinase TK gene driven by the SPARC promoter in combination with ganciclovir inhibited human melanoma cell growth in monolayer as well as in multicellular spheroids. Patricia Blanco:
Transcriptional targeting consists in the use of tumor-specific gene promoters TSP to direct the expression of therapeutic genes specifically to a tumor 5. In the past several decades, the incidence of malignant melanoma has increased more than any other cancer. Share this Rating Title: Thus, using a TSP whose activity is restricted only to a subset of malignant cells where the selected TSP is active might allow remaining malignant cells to escape this specific therapy and stromal cells to continue supporting malignant cell growth. A glial-specific, repressible, adenovirus vector for brain tumor gene therapy. Our data suggest that the use of therapeutic genes driven by SPARC promoter could be a valuable strategy for cancer therapy aiming to target all the cellular components of the tumor mass. In the entire set of experiments, ganciclovir had only minimal effect on spheroid growth in the absence of TK expression data not shown.
