All breast cancers are not created equal. In up to 70 percent of all breast cancers, the tumor has receptors for the hormone estrogen. Today, these estrogen-receptor-positive cancers can be treated relatively well. Because these tumors need estrogen for their growth, the receptor is the target of a number of drugs that interfere with estrogen expression, bind to the receptor or speed up its degeneration. However, around a third of all patients does not react to therapy or develops resistance. So far it has not been possible to accurately predict who will respond to this therapy because the underlying molecular mechanisms are not yet understood entirely.

In a comprehensive molecular study, a group of scientists led by Prof. Mohamed Bentires-Alj from the Department of Biomedicine at the University and the University Hospital of Basel has now identified an important player in this process named LATS. They were able to show how this enzyme, in cooperation with other proteins, influences the development and treatment of breast cancer.

Researchers - Genes - Cells - Tumor - Suppressors

The researchers focused on cancer-inhibiting genes that prevent normal cells from becoming cancerous. In particular, they studied the tumor suppressors LATS1...
