Circulating Cancer Cells Torpedoed by Peptide–Chemo Conjugate

Cancer presents a moving target called metastasis that keeps ducking countermeasures. But metastasis can be targeted, animal studies have shown, by agents that bind to the surface proteins that are found on circulating cancer cells. According to a new study, one such agent, called 123B9, can be linked to a chemotherapeutic drug, paclitaxel, resulting a new and potentially effective countermeasure against metastatic cancer.Cancer drugs usually target stationary targets such as tumors . But when c
