L-methionine-induced alterations in molecular signatures in MCF-7 and LNCaP cancer cells.

Background: Methionine inhibits proliferation of breast and prostate cancer cells. Here, we determined the influence of L-methionine on functional molecular signatures in these cell lines.

Methods: MCF-7 and LNCaP cells were treated with L-methionine (5 mg/ml) for 72 h.
