Using two-dimensional (2-D) electrophoresis, two non-histone chromatin protein fractions (NHCP1 and NHCP2) from three animal tumours (Kirkman-Robbins hepatoma, Morris hepatoma 7777 and Ehrlich ascites cells) and normal hamster liver were analyzed. Apart from many common components several tissue specific polypeptides of the NHCP1 and NHCP2 fractions were detected. It was found that some spots present in electropherograms of non-histone proteins of tumour cells (M X 10(-3)/pI): 17-24/4.9-6.5 (NHCP1 and NHCP2); 34-41/4.9-6.0 (HCP1 and NHCP2); 44-46/5.3-7.5 (HCP2); 46-49/5.0-7.5 (NHCP1); 49/5.9-7.5 (NHCP2) and 102-134/5.6-7.0 (NHCP1) were absent from normal liver.

D002286 Carcinoma, Ehrlich Tumor A transplantable, poorly differentiated malignant tumor which appeared originally as a spontaneous breast carcinoma in a mouse. It grows in both solid and ascitic forms. Ehrlich Ascites Tumor,Ascites Tumor, Ehrlich,Ehrlich Tumor Carcinoma,Tumor, Ehrlich Ascites
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
D002843 Chromatin The material of CHROMOSOMES. It is a complex of DNA; HISTONES; and nonhistone proteins (CHROMOSOMAL PROTEINS, NON-HISTONE) found within the nucleus of a cell. Chromatins
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.

D006224 Cricetinae A subfamily in the family MURIDAE, comprising the hamsters. Four of the more common genera are Cricetus, CRICETULUS; MESOCRICETUS; and PHODOPUS. Cricetus,Hamsters,Hamster
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.
