The synthesis of nuclear histones in early embryogenesis.
These results confirm and extend those of earlier investigations showing that actinomycin D affects the synthesis of histones in the early stages of development of the sea urchin embryo. Actinomycin D has a differential effect on the rates of synthesis of four classes of histones under a variety of conditions. It consistently and markedly inhibits the synthesis of the acid-soluble, lysine-rich ...
متن کاملPaternal effects on early embryogenesis
Historically, less attention has been paid to paternal effects on early embryogenesis than maternal effects. However, it is now apparent that certain male factor infertility phenotypes are associated with increased DNA fragmentation and/or chromosome aneuploidies that may compromise early embryonic development. In addition, there is a growing body of evidence that the fertilizing sperm has more...
متن کاملBivalent histone modifications in early embryogenesis.
Histone modifications influence the interactions of transcriptional regulators with chromatin. Studies in embryos and embryonic stem (ES) cells have uncovered histone modification patterns that are diagnostic for different cell types and developmental stages. For example, bivalent domains consisting of regions of H3 lysine 27 trimethylation (H3K27me3) and H3 lysine 4 trimethylation (H3K4me3) ma...
متن کاملThe role of neurohumors in early embryogenesis
In a previous paper (Buznikov, Chudakova & Zvezdina, 1964) it has been reported that serotonin (5-hydroxytryptamine, 5-HT) may be involved in early embryogenesis in various groups of animals. This conclusion was confirmed by Baker's recent publication (Baker, 1965) concerning 5-HT synthesis in Xenopus laevis embryos. Some other low molecular weight substances, neurohumors or related compounds, ...
متن کاملThe role of neurohumours in early embryogenesis
In previous papers (Buznikov, Chudakova & Zvezdina, 1964; Buznikov, Chudakova, Berdysheva & Vyazmina, 1968) we reported that fertilized eggs of the sea-urchin Strongylocentrotus dwbachiensis synthesized a number of neurohumours, such as serotonin (5-hydroxytryptamine, 5-HT), acetylcholine (ACh), adrenalin (A), noradrenalin (NA) and dopamine. Synthesis of 5-HT was also demonstrated in the fertil...
