title: Iron transport in NRK cells synchronized in G(1) by picolinic acid.
abstract: NRK cells treated with picolinic acid are arrested in G(1)(G0). After removal of the agent a wave of transferrin-dependent iron uptake was observed only in early G(1). Therefore, iron transport is a primary event in the reinitiation of cell growth and may be connected with subsequent metabolic steps leading to initiation of DNA synthesis.
