[Mechanism of silybin action, III. Resorption of the flavonolignane derivative silybin into rat liver cells (author's transl)]. 1980

J Sonnenbichler, and J Mattersberger, and G Hanser

After tritium labelling of silybin the time-dependent uptake of the flavonolignane derivative into rat liver was measured. Within the liver cells the distribution of silybin (and -metabolites) in cytosol, nuclear constituents and membrane material was determined and the accumulation of the flavonolignane derivative in cytosol and nuclear membranes confirmed by autoradiography. Within the nuclei a preferential binding on chromosomal proteins was found.

D009698	Nucleoproteins	Proteins conjugated with nucleic acids.	Nucleoprotein
D011485	Protein Binding	The process in which substances, either endogenous or exogenous, bind to proteins, peptides, enzymes, protein precursors, or allied compounds. Specific protein-binding measures are often used as assays in diagnostic assessments.	Plasma Protein Binding Capacity,Binding, Protein
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

D000818	Animals	Unicellular or multicellular, heterotrophic organisms, that have sensation and the power of voluntary movement. Under the older five kingdom paradigm, Animalia was one of the kingdoms. Under the modern three domain model, Animalia represents one of the many groups in the domain EUKARYOTA.
