The mechanisms that silence the estrogen receptor gene alpha, in certain breast cancer cell lines may be closer to being unlocked, according to a new study. The researcher says this study provides a basis for understanding how the complex pattern of estrogen receptor gene alpha methylation and transcriptional silencing is generated, as well as for understanding the relationship between this pattern and its function during breast cancer progression. By understanding this mechanism, scientists say, researchers will be able to design therapies and drugs that are very precise in the target they recognize.
