Research aims to starve breast cancer cells
Date:8/29/2011

m like a loss for healthy cells, it bolsters the cancer-fighting potential for drugs that block SLC6A14 by making it a more specific cancer target. "Since the normal cells do not depend on this transporter, you can use a drug that selectively blocks it to target cancer cells" Ganapathy said.

The compound they used is alpha-methyl-DL-tryptophan, already used in humans for short periods when they are getting a PET scan in certain areas of the brain. When the researchers treated estrogen receptor-positive breast cancer cells with it or put it in the drinking water of the mice with the cells, rapid growth stopped and the cancer cells died. Further studies showed alpha-methyl-DL-tryptophan seemed to impact only cells expressing the SLC6A14 transport system. Even another type of breast cancer, estrogen receptor-negative, wasn't impacted.
