title: Heavy incorporation of 3H-prostaglandin F2 alpha in the neoplastic cells as revealed by autoradiographic studies.
abstract: A marked uptake (9-fold) of the 3H-PGF2 alpha was found specifically over heterochromatin in the nuclei of neoplastic cells. Lower but significant uptakes of 3H-PGF2 alpha were also found in the nuclei of control epidermal cells, which indicate the presence of nuclear receptors in the epidermal neoplastic cells.
