Patent

CA 2665371

Herein disclosed is an alternatively-spliced [AS] variant of MN/CA9 mRNA and its related protein - AS MN/CA IX. Unlike the tumor-associated, full- length [FL] MN/CA9 mRNA and FL MN/CA IX, which in most tissues signify oncogenesis and/or hypoxia, the AS MN/CA9 mRNA is constitutively-expressed under normoxia and is not stimulated by hypoxia, and the AS MN/CA IX is not confined to the cell membrane. Provided herein are diagnostic/ prognostic methods for preneoplastic/neoplastic disease to differentiate between AS and FL MN/CA9 expression, and probes, primers, and antibodies useful in such methods. Also disclosed are methods to treat pre-neoplastic/neoplastic disease involving the MN gene and protein, which methods are based on the ability of AS MN protein (AS MN/CA IX) to interfere with the catalytic activity of FL MN protein (FL MN/CA IX); such methods may also use AS MN protein fragments that have that interference capability. Such methods may comprise increasing the levels of AS MN/CA IX relative to the levels of FL MN/CA IX. Exemplary therapeutic methods may comprise the administration of agents, such as, AS MN/CA IX itself, a vector expressing AS MN/CA9 mRNA, an antisense oligonucleotide that blocks expression of FL MN/CA IX but not that of AS MN/CA IX, a vector expressing such an antisense oligonucleotide, a FL MN/CA9 isoform-specific siRNA, or a vector expressing such FL MN/CA9 isoform-specific siRNA. Further disclosed are methods to identify agents capable of modulating levels of AS MN/CA IX.

L'invention concerne un variant ayant subi un épissage alternatif [AS] de l'ARNm MN/G49 et sa protéine apparentée AS MN/CA IX. Contrairement à l'ARNm [FL] MN/C/49 de longueur complète, associé aux tumeurs et à FL MN/CA IX1, qui signifient dans la plupart des tissus, une oncogenèse et/ou une hypoxie, l'ARNm AS MWCA9 est exprimé de manière constitutive dans des conditions de normoxie et n'est pas stimulé par l'hypoxie, et AS MN/CA IX n'est pas confinée dans la membrane cellulaire. L'invention concerne en outre des procédés diagnostiques/pronostiques pour maladie pré-néoplasique/néoplasique, pour différencier l'expression de AS et de FL MN/CA9, et des sondes, amorces et anticorps utiles dans de tels procédés. L'invention concerne également des procédés pour traiter une maladie pré-néoplasique/néoplasique impliquant le gène et la protéine MN, lesquels procédés sont basés sur la capacité de la protéine AS MN (comme AS MN/CA IX) à interférer avec l'activité catalytique de la protéine FL MN (FL MN/CA IX); de tels procédés peuvent également utiliser des fragments de la protéine AS MN, qui ont cette capacité d'interférence. Ces procédés peuvent comprendre l'augmentation des taux de AS MN/CA IX par rapport aux taux de FL MN/CA IX. Des procédés thérapeutiques exemplaires peuvent comprendre l'administration d'agents, comme AS MN/CA IX elle-même, un vecteur exprimant l'ARNm AS MN/CA IX, un oligonucléotide antisens, qui bloque l'expression de FL MN/CA IX, mais pas celle d AS MN/CA IX, un vecteur exprimant un tel oligonucléotide antisens, un ARNsi spécifique de l'isoforme FL MN/CA 9, ou un vecteur exprimant un tel ARNsi spécifique de l'isoforme FL MN/CA 9. On décrit en outre, des procédés pour identifier des agents capables de moduler les taux en AS MN/CA IX.
