In the article by J. Jongsma et al.,entitled “Androgen Deprivation of the Prohormone Convertase-310 Human Prostate Cancer Model System Induces Neuroendocrine Differentiation,”which appeared in the February 1, 2000 issue of Cancer Research (pp. 741–748), the title appeared incorrectly. The correct title should read: “Androgen Deprivation of the PC-310 Human Prostate Cancer Model System Induces Neuroendocrine Differentiation.”
