Ultrastructure of hepatocyte nuclei in irradiated, adrenalectomized rats. 1984

S Orkisz, and H Bartel, and B Kmieć

A cytochemical study of hepatocyte nuclei of adrenalectomized and irradiated rats were performed. After irradiation alone the behaviour of the ribonucleoprotein components was studied according to Bernhard. The findings suggested that a delay occurs in the synthesis of preribosomal RNA in the nucleoli and in the transport of messenger RNA to the cytoplasm. The indirect effect of ionizing radiation on nuclear RNA synthesis is assumed to occur through the influence of cortical steroid hormones on the transcription process.

D002467	Cell Nucleus	Within a eukaryotic cell, a membrane-limited body which contains chromosomes and one or more nucleoli (CELL NUCLEOLUS). The nuclear membrane consists of a double unit-type membrane which is perforated by a number of pores; the outermost membrane is continuous with the ENDOPLASMIC RETICULUM. A cell may contain more than one nucleus. (From Singleton & Sainsbury, Dictionary of Microbiology and Molecular Biology, 2d ed)	Cell Nuclei,Nuclei, Cell,Nucleus, Cell
