Hepatoma-associated nonhistone chromosomal proteins. 1984

A L Burkhardt, and D P Huang, and J F Chiu

In order to compare nonhistone proteins in normal and neoplastic hepatocytes, we elicited antisera to Morris hepatoma 7777 dehistonized chromatin. By the enzyme-linked immunosorbent assay, the antisera demonstrated specificity for Morris hepatoma 7777 and little reactivity to normal rat liver chromatin. Morris hepatomas 7288c, 7800 and 5123tc shared some antigenic hepatoma nonhistone proteins. Neoplasia induced in rats fed 3'-methyl-4-dimethylaminoazobenzene changed the immunospecificity of the liver chromatin to a new type that was antigenically similar to Morris hepatoma 7777. Fetal rat liver chromatin and regenerating rat liver chromatin did not bind antibody. To further characterize the antigenic nonhistone proteins, we analyzed Morris hepatoma 7777 chromatin and normal rat liver chromatin by the immunoblot technique. Nonhistone proteins that demonstrated immunoreactivity were predominantly high molecular weight proteins.

D002868	Chromosomal Proteins, Non-Histone	Nucleoproteins, which in contrast to HISTONES, are acid insoluble. They are involved in chromosomal functions; e.g. they bind selectively to DNA, stimulate transcription resulting in tissue-specific RNA synthesis and undergo specific changes in response to various hormones or phytomitogens.
