Patent

CA 2344995

Cancer associated antigens have been identified by autologous antibody screening of libraries of nucleic acids expressed in renal cancer cells using antisera from cancer patients. The invention relates to nucleic acids and encoded polypeptides which are cancer associated antigens expressed in patients afflicted with renal cancer. The invention provides, inter alia, isolated nucleic acid molecules, expression vectors containing those molecules and host cells transfected with those molecules. The invention also provides isolated proteins and peptides, antibodies to those proteins and peptides and cytotoxic T lymphocytes which recognize the proteins and peptides. Fragments of the foregoing including functional fragments and variants also are provided. Kits containing the foregoing molecules additionally are provided. The molecules provided by the invention can be used in the diagnosis, monitoring, research, or treatment of conditions characterized by the expression of one or more cancer associated antigens.

Des antigènes associés au cancer du rein ont pu être identifiés par criblage à l'aide d'anticorps autologues de bibliothèques d'acides nucléiques exprimés par les cellules cancéreuses du rein en utilisant des antisérums de patients cancéreux. L'invention porte sur des acides nucléiques et les polypeptides codés par eux qui sont des antigènes associés au cancer exprimés par des patients atteints du cancer du rein. L'invention porte notamment sur des molécules isolées d'acide nucléique, sur des vecteurs d'expression contenant ces molécules, et sur des cellules hôtes transfectées par ces molécules. L'invention porte également sur des protéines et des peptides isolés anticorps des protéines et des peptides et des lymphocytes T cytotoxiques qui reconnaissent lesdites protéines et lesdits peptides. L'invention porte en outre sur de leurs fragments dont des fragments fonctionnels et leurs variantes. Elle porte enfin sur des trousses contenant les susdites molécules. Les molécules de l'invention peuvent servir au diagnostic, au suivi, à la recherche ou au traitement d'états caractérisés par l'expression d'un ou plusieurs antigènes associés au cancer.
