[The effects of dopa and oxygen on RNA concentrations in cultured chick embryonal retinal pigment epithelial cells].

Abstract

We measured RNA and DNA concentrations in cultured chick embryonal retinal pigment epithelial cells to investigate the effects of dopa and oxygen on DNA and RNA synthesis. RNA/DNA ratios were decreased by addition of 250 microM dopa. Decrease of RNA/DNA ratios was suppressed when the oxygen concentrations were reduced from 20% to 10%. Incubation with medium… (More)
