CA 2241317

The present invention provides polynucleotide sequences designated PANC1A and PANC1B which are associated with a genomic sequence related to pancreatic cancer as well as other cancers. The present invention also provides for PANC1A and PANC1B antisense molecules. The invention further provides genetically engineered expression vectors and host cells for the production of purified PANC1A and PANC1B polypeptide; antibodies, antagonists and inhibitors of PANC1A and PANC1B polypeptide; and pharmaceutical compositions and methods of treatment based on the polypeptide, its antibodies, antagonists and inhibitors. The invention specifically provides for use of the polypeptide as a diagnostic composition for the detection of pancreatic cancer in individuals at risk for and subject to pancreatic cancer. The invention also relates to therapeutic methods and compositions based upn the nucleotide sequences for PANC1A and PANC1B.

L'invention concerne des séquences de polynucléotides dénommées PANC1A et PANC1B, qui sont associées à une séquence génomique en relation avec le cancer du pancréas ainsi qu'avec d'autres cancers. Elle concerne également des molécules antisens correspondant à PANC1A et PANC1B; des vecteurs d'expression et des cellules hôtes mis au point par génie génétique, destinés à la production du polypeptide PANC1A et du polypeptide PANC1B purifié; des anticorps, des antagonistes et des inhibiteurs des polypeptides PANC1A et PANC1B; et des compositions pharmaceutiques et des méthodes de traitement basées sur lesdits polypeptides, leurs anticorps, antagonistes et inhibiteurs. L'invention concerne spécifiquement l'utilisation des polypeptides comme composition diagnostique permettant de détecter le cancer du pancréas chez les individus qui sont prédisposés à ce type de cancer ou en sont déjà porteurs. Elle concerne enfin des méthodes et des compositions thérapeutiques basées sur les séquences de nucléotides correspondant à PANC1A et PANC1B.
