Research breakthrough could halt melanoma metastasis
Date:11/14/2012

Additionally, the team found that levels of mda-9/syntenin were higher than levels of RKIP in malignant and metastatic melanoma cells while levels of RKIP were higher than levels of mda-9/syntenin in healthy melanocytes, which are the cells that produce pigment in the skin, eyes and hair. The inverse relationship between the two proteins suggests that changes in their levels of expression could be used as a diagnostic tool, enabling clinicians to track the development of the disease or gauge a patient's response to treatments.

"Our findings represent a major breakthrough in understanding the genetic mechanisms that lead to metastasis in melanoma. Prior studies have shown that levels of mda-9/syntenin are elevated in a majority of cancers, including melanoma, suggesting that our findings could be applicable for a wide range of diseases," says Fisher.

Now that the researchers have demonstrated the ability of RKIP to inhibit mda-9/syntenin-mediated metastasis, they are focusing their attention on developing small molecules imitating RKIP that could be used as new treatments for melanoma.
