  • Title: Mitochondrial protein synthesis in interspecific somatic cell hybrids.
    Author: Zuckerman SH, Gillespie FP, Solus JF, Rybczynski R, Eisenstadt JM.
    Journal: Somat Cell Mol Genet; 1986 Sep; 12(5):449-58. PubMed ID: 3464102.
    Abstract:
    The fusion of an oligomycin (OLI)-resistant mutant of mouse LM(TK-) cells to a chloramphenicol (CAP)-resistant mutant of AK412 Chinese hamster cells resulted in a series of interspecific somatic cell hybrids. Hybrids selected in HAT medium retained only mouse mitochondrial genomes while hybrids selected in HAT plus CAP and OLI retained both hamster and mouse mitochondrial genomes in approximately equal amounts. Nuclear-coded mitochondrial proteins from both parental species were incorporated into mitochondria in all of the hybrids. However, the mitochondrially coded proteins of three individually isolated hybrid cell lines were predominantly mouse-specific, with only trace amounts of hamster protein detected.
