CROMOSOMA HUMANO [2 records]

Record 1 2012-02-15

English

Subject field(s)
  • Biochemistry
  • Viral Diseases
DEF

A host-encoded siaglycoprotein which is found in all mammals examined to date.

OBS

It occurs in two forms at least: the cellular, normal form (PrPc) and the disease-causing abnormal form (PrPsc).

French

Domaine(s)
  • Biochimie
  • Maladies virales
DEF

Sialoglycoprotéine codée à partir d'un gène cellulaire simple identifié chez tous les mammifères étudiés.

OBS

Elle existe sous deux isoformes : une forme normale, non infectante appelée PrPc (pour cellulaire) et une forme anormale appelée PrPres (pour résistante à la protéinase K).

Spanish

Campo(s) temático(s)
  • Bioquímica
  • Enfermedades víricas
CONT

Existe una proteína prión normal presente en las membranas de las células nerviosas, codificada por un gen celular localizado en el cromosoma humano 20.

Record 2 2007-08-08

English

Subject field(s)
  • Genetics
CONT

Human artificial chromosomes (HAC) have been considered as a possible vector for human gene therapy. In our previous work a minichromosome (MC), isolated from a patient, was transformed with a selectable marker gene (neo) which was targeted into its centromere; the MC was then size reduced, by X-ray exposure, to be easily manipulated and further engineered. The method developed for gene targeting, based on the use of chromosome specific centromeric satellite DNA as transfection carrier, is highly efficient and reproducible.

French

Domaine(s)
  • Génétique
CONT

En effet, les chromosomes artificiels humains (HAC) décrits constituent les premières constructions chromosomiques possédant tous les attributs (télomères, origines de réplication, centromère) d'un chromosome humain viable. [...] Les généticiens manquent encore d'informations précises sur les séquences qui, au niveau du centromère et des origines de réplications, sont nécessaires au fonctionnement du chromosome.

Spanish

Campo(s) temático(s)
  • Genética
DEF

Construcción análoga al cromosoma artificial de levadura, que consta de un centrómero y telómeros de origen humano, que permitiría la clonación de fragmentos de ADN muy grandes y su transferencia a las células humanas para aplicar la terapia génica.
