changes in cell fine structure during lens regeneration in xenopus laevis. | changes at the level of cell fine structure have been studied during lens regeneration in the toad, xenopus laevis, where cornea gives rise to the new lens. the transformation of these cells may be divided into three phases. (1) in the cornea, flattened cells become cuboidal and rough endoplasmic reticulum increases in amount. (2) in the new lens vesicle, cisternae of the rough er break down into vesicles, smooth-walled vesicles and free ribosomes increase in number, and mitochondria can become ... | 1965 | 14326107 |

a comparative study in vivo and in vitro of the ability of ribosomes from xenopus liver and ovary to incorporate l-[u-14c]leucine. | 1. a system for the incorporation in vitro of amino acids into protein is described for the south african clawed toad (xenopus laevis laevis daudin). 2. the incorporation of l-[u-(14)c]leucine by xenopus-liver microsomes is very much greater per mg. of microsomal rna than the incorporation by ovary microsomes. 3. the incorporation by xenopus-liver and -ovary polysomes is approximately the same when expressed per mg. of polysomal rna. 4. it was predicted from the above results that ovary microsom ... | 1966 | 5966272 |

retinal ganglion cells: specification of central connections in larval xenopus laevis. | in a series of xenopus larvae (stages 28 to 35), the left eye cup was dorsoventrally and anteroposteriorly inverted. after metamorphosis, the retinotectal projection was mapped by recording action potentials evoked in the tectum by a small spot of light projected on the retina. normal retinotectal projection was found following rotation of the eye cup at stage 28 to 29. rotation of the eye cup at stage 30 resulted in anteroposterior inversion of the retinotectal projection; rotation at stages 31 ... | 1967 | 6021901 |

fine structure of rna codewords recognized by bacterial, amphibian, and mammalian transfer rna. | nucleotide sequences of 50 rna codons recognized by amphibian and mammalian liver transfer rna preparations were determined and compared with those recognized by escherichia coli transfer rna. almost identical translations were obtained with transfer rna from guinea pig liver, xenopus laevis liver (south african clawed toad), and e. coli. however, guinea pig and xenopus transfer rna differ markedly from e. coli transfer rna in relative response to certain trinucleotides. transfer rna from mammal ... | 1967 | 5335001 |

ornithine-urea cycle activity in xenopus laevis: adaptation in saline. | the concentration of urea in the blood and the rate of urea excretion were markedly elevated in xenopus maintained in hypertonic saline for 2 to 3 weeks. these changes were accompanied by a twofold increase in the activity of the ornithine-urea cycle as measured in liver slices. the activity of carbamoyl phosphate synthetase rose threefold in frogs adapted to saline. these results suggest that changes in activities of urea cycle enzymes may be important in the adaptation of aquatic organisms to ... | 1967 | 5212401 |

renaturation and hybridization studies of mitochondrial dna. | the products of the renaturation reaction of mitochondrial dna from oocytes of xenopus laevis have been studied by electron microscopy and cscl equilibrium density gradient centrifugation. the reaction leads to the formation of intermediates containing single-stranded and double-stranded regions. further reactions of these intermediates result in large complexes of interlinking double-stranded filaments. the formation of circular molecules of the same length as native circles of mitochondrial dn ... | 1968 | 5641404 |
estrogen induces lipophosphoprotein in serum of male xenopus laevis. | administration of estradiol 17beta to male xenopus laevis induces the appearance in serum of large amounts of a serum lipophosphoprotein which is not readily removed from the circulation and which can be resolved from other serum components by chromatography on triethylaminoethyl-cellulose. the initial rate of production of serum lipophosphoprotein is independent of the amount of estrogen administered, but the maximum rate of production and the time taken to attain this rate are dose-dependent. | 1968 | 5642316 |
