Cancer cells deviate from normal cell function by their out-of-control division and replication. Their ramped up metabolism depends on a continuous supply of certain nutrients. Identifying and then blocking cancer cells’ access to these essential nutrients can block the growth and spread of some cancers. Triple Negative Breast Cancer (TNBC) is not estrogen-dependent and hence does not respond to estrogen-blocking medications, leaving TNBC patients with less effective treatment options, but there is new hope. Duke University scientists have identified an amino acid to which TNBC cells are addicted, opening big doors of possibility that blocking access to the amino acid could offer an effective treatment option for some TNBC patients.
