Cytoplasmic Dna Synthesis
The incorporation of tritiated thymidine in Amoeba proteus was reinvestigated in order to see if it could be associated with microscopically detcctable structures. Staining experiments with basic dyes, including the fluorochrome acridine orangc, revealed the presence of large numbers of 0.3 to 0.5 # particles in the cytoplasm of all cells studied. The cffcct of nuclease digestion on the dye aff...
متن کاملChanges of Nerve Growth Factor Synthesis in Nonneuronal Cells in Response to Sciatic Nerve Transection
The intact sciatic nerve contains levels of nerve growth factor (NGF) that are comparable to those of densely innervated peripheral target tissues of NGF-responsive (sympathetic and sensory) neurons. There, the high NGF levels are reflected by correspondingly high mRNA N~F levels. In the intact sciatic nerve, mRNA N~F levels were very low, thus indicating that the contribution of locally synthe...

The intact sciatic nerve contains levels of nerve growth factor (NGF) that are comparable to those of densely innervated peripheral target tissues of NGF-responsive (sympathetic and sensory) neurons. There, the high NGF levels are reflected by correspondingly high mRNANGF levels. In the intact sciatic nerve, mRNANGF levels were very low, thus indicating that the contribution of locally synthesi...

متن کاملCytoplasmic Dna Synthesis in Amoeba Proteus
The application of electron microscope autoradiography to Amoeba proteus cells labeled with tritiated thymidine has permitted the identification of morphologically distinct particles in the cytoplasm as the sites of incorporated DNA precursor. The particles correspond to those previously described from light microscope studies, with respect to both H(3)Tdr incorporation and distribution in cent...
