New solution for therapeutic cancer vaccine failure

submitted by: mdanderson
http://www.mdanderson.org/newsroom/news-releases/2013/cancer-vaccines-ch... Vaccines designed to turn the immune system against cancer have been logically constructed and tested against many cancers. Almost all have failed or shown minimal effect. They spark creation of killer T cells against the cancer, but generally have little effect on tumors, both in patients and mouse models. Willem Overwijk, Ph.D., and colleagues at MD Anderson discovered that a common vaccine component is...

Endothelin-1 is a transcriptional target of p53 in epidermal keratinocytes and regulates UV induced melanocyte homeostasis

submitted by: arup.indra
Keratinocytes contribute to melanocyte activity by influencing their microenvironment, in part, through secretion of paracrine factors. Here we discovered that p53 directly regulates Edn1 expression in epidermal keratinocytes and controls UV-induced melanocyte homeostasis. Selective ablation of EDN1 in murine epidermis (EDN1ep-/-) does not alter melanocyte homeostasis in newborn skin but decreases dermal melanocytes in adult skin. Results showed that keratinocytic EDN1 in a non-cell...
