Alphabetical list of terms

Record 1 2013-08-13

English

Subject field(s)
  • Biotechnology
  • Genetics
CONT

Neurons from the embryonic brain of Xenopus were transfected in vivo with a vector expressing luciferase cDNA [complementary DNA] using a simple lipofection procedure. Luciferase activity was monitored quantitatively, and the protein was immunolocalized in whole-mount embryonic brain.

French

Domaine(s)
  • Biotechnologie
  • Génétique
CONT

La lipofection voit également son importance augmenter, principalement en cancérologie dans le sillage des essais de Nabel et al. dont les résultats cliniques d'injections intramusculaires immunisantes ont été encourageants.

Spanish

Campo(s) temático(s)
  • Biotecnología
  • Genética
DEF

[Técnica de] introducción, en células eucariotas, de ADN, ARN o de otros compuestos, previamente encapsulados en liposomas.

Record 2 2013-04-02

English

Subject field(s)
  • Medication
  • Molecular Biology
DEF

Any of a group of peptides with antimicrobial properties.

CONT

Antitumor activity of magainin analogues against human lung cancer cell lines [compounds] originally isolated from African clawed frog Xenopus laevis skin, [that) inhibit the growth of bacteria and fungi.

OBS

From Hebrew "mágèn" (shield).

French

Domaine(s)
  • Médicaments
  • Biologie moléculaire
CONT

Magainin Pharmaceuticals et Sandoz s'associent pour développer et commercialiser des agents anticancéreux dérivés de l'antibiotique magainin, une molécule extraite de la peau de grenouille.

Record 3 2002-01-08

English

Subject field(s)
  • Mollusks, Echinoderms and Prochordates
CONT

We injected the frog kidney nuclei into the oocytes of the newt Pleurodeles waltlii whose proteins can be distinguished from those of Xenopus on two-dimensional gels.

CONT

... newts, crayfish and other crawling things ...

French

Domaine(s)
  • Mollusques, échinodermes et procordés
CONT

Nous avons injecté des noyaux de cellules rénales de Xénope dans des ovocytes du triton Pleurodeles waltlii dont les protéines peuvent être distinguées de celles du Xénope sur les gels bidimensionnels.

Record 4 1991-07-17

English

Subject field(s)
  • Cytology
CONT

Recently, several mesoderm-inducing factors(MIFs) have been discovered. These cause isolated Xenopus animal caps to form mesodermal cell types such as muscle, instead of their normal fate of epidermis. The MIFs fall into two classes. One comprises members of the fibroblast growth factor(FGF) family, and the other members of the transforming growth factor type beta(TGF-beta) family. Of the latter group, the most potent is XTC-MIF, a protein produced by Xenopus XTC cells. Here we show that XTC-MIF is the homologue of mammalian activin A.

OBS

Tiré du périodique londonien: Nature, 1990, 345 (6277), pp. 729-731.

French

Domaine(s)
  • Cytologie
CONT

Les activines, des inducteurs du mésoderme axial chez le xénope et le poulet. Nous avons rapporté, dans une brève récente, que l'inducteur mésodermique XTC-MIF (mesoderm inducing factor dérivé de la lignée de xénope XTC), appartenant à la famille TGF B, était l'équivalent de l'activine chez Xenopus.

We injected the frog kidney nuclei into the oocytes of the newt Pleurodeles waltlii whose proteins can be distinguished from those of Xenopus on two-dimensional gels.

French

Domaine(s)
  • Reptiles et amphibiens

Record 6 1980-08-06

English

Subject field(s)
  • Reptiles and Amphibians
OBS

(...) the genes that code for 5S ribosomal RNA in the frog Xenopus borealis were injected into oocytes of X. laevis.

French

Domaine(s)
  • Reptiles et amphibiens
OBS

Dans ces expériences, les gènes codant pour le RNA ribosomique "5S" (5S veut dire cinq unités Svedberg) de l'espèce Xenopus borealis furent injectés dans des ovocytes de X. Laevis.

Subject field(s)
  • Reptiles and Amphibians
OBS

The source of oocytes for most of our experiments is Xenopus laevis, a South African frog particularly well suited for laboratory conditions.

French

Domaine(s)
  • Reptiles et amphibiens
OBS

(...) nous avons utilisé les ovocytes de Xenopus laevis, un anoure d'Afrique du Sud particulièrement adapté aux études en laboratoire.
