The Ribosomal Rna of Hamster-mouse Hybrid Cells
The ribosomal RNA (rRNA) of a series of hamster-mouse somatic cell hybrids was studied. Mouse 28S rRNA was separated from its hamster counterpart by a two-step procedure involving sucrose gradient centrifugation of ribosomes and polyacrylamide gel electrophoresis of rRNA. Both hamster and mouse types of rRNA were synthesized in the 11 hybrids tested, including hybrids containing only about one-...
متن کاملEvaluation of the mutagenic effects of SV40 in mouse, hamster, and mouse-human hybrid cells.
We have examined the ability of SV40 to induce changes in drug or temperature resistance in mouse, hamster, and mouse-human hybrid cells. SV40 induced a substantial increase of cells resistant to 5-bromodeoxyuridine + trifluorothymidine in Balb/c 3T3 cells and induced an increase of hybrid cells resistant to 6-thioguanine. SV40 was found to be nonmutagenic or weakly mutagenic in other test syst...
متن کاملInterspecific recombination of mitochondrial DNA molecules in hybrid somatic cells.
The mitochondrial DNA (mtDNA) in rodent-human hybrid somatic cells was studied in strains that contain nucleotide sequences from both parental mtDNAs. A test for linkage of rodent to human mtDNA was devised on the basis of the density and sequence differences between these DNAs. When a mixture of rodent and human mtDNAs was banded in a CsCl gradient and each fraction hybridized with a mixture o...
متن کاملSynchronization of Mitochondrial Dna Synthesis in Chinese Hamster Cells (line Cho) Deprived of Isoleucine
Mitochondrial DNA (mit-DNA) synthesis was compared in suspension cultures of Chinese hamster cells (line CHO) whose cell cycle events had been synchronized by isoleucine deprivation or mitotic selection. At hourly intervals during cell cycle progression, synchronized cells were exposed to tritiated thymidine ([(3)H]TdR), homogenized, and nuclei and mitochondria isolated by differential centrifu...
متن کاملRevisiting the mouse mitochondrial DNA sequence.
The existence of reliable mtDNA reference sequences for each species is of great relevance in a variety of fields, from phylogenetic and population genetics studies to pathogenetic determination of mtDNA variants in humans or in animal models of mtDNA-linked diseases. We present compelling evidence for the existence of sequencing errors on the current mouse mtDNA reference sequence. This includ...
