Fishing in the (deoxyribonucleotide) pool.
Deoxyribonucleoside triphosphates (dNTPs) are the building blocks of DNA, and a constant supply is essential for the synthesis and maintenance of both the nuclear and mitochondrial genomes. Antiviral nucleoside analogues and inborn errors of nucleotide metabolism frequently cause dNTP pool imbalances, leading to depletion of mtDNA (mitochondrial DNA) in nonreplicating tissues. mtDNA depletion, ...
متن کاملIn vitro experiments with primary mammalian cells: to pool or not to pool?
There are various strategies that can be adopted when performing in vitro experiments with primary cells such as mesenchymal stem cells. It is generally accepted that multiple donors need to be investigated to take into account donor to donor variability; this is especially critical when investigating primary human cells. However, increasingly it is being seen that studies are pooling the cells...
متن کاملHeteroduplex-induced mutagenesis in mammalian cells.
We have shown previously that heteroduplexes containing single-stranded loops are repaired efficiently in monkey cells, but not always correctly: 2% of the repair products acquired mutations within a 350 base-pair target (Weiss, U. and Wilson, J.H., Proc. Natl. Acad. Sci. USA 87:1123-1126, 1987). The structures of the mutant genomes, which are described here, are consistent with an error-prone ...
متن کاملBuffering of deoxyribonucleotide pool homeostasis by threonine metabolism.
Synergistically interacting gene mutations reveal buffering relationships that provide growth homeostasis through their compensation of one another. This analysis in Saccharomyces cerevisiae revealed genetic modules involved in tricarboxylic acid cycle regulation (RTG1, RTG2, RTG3), threonine biosynthesis (HOM3, HOM2, HOM6, THR1, THR4), amino acid permease trafficking (LST4, LST7), and threonin...
متن کاملCytoplasmic pool of histone H1 in mammalian cells.
Two types of cell populations, nondividing mouse liver cells and exponentially growing Friend erythroleukemia cells, were studied for the presence of a histone H1 pool in the cytoplasm. Purified cytoplasmic fractions were extracted with 5% perchloric acid and the resulting protein preparation was characterized by two types of electrophoresis, gel filtration, peptide mapping, ELISA and immunoblo...
