CA 2465274

A highly sensitive assay is disclosed which utilizes a method for gene specific primed amplification of mRNA libraries from rare cells and rare transcripts found in blood. The assay allows detection of rare mRNA (10 copies/cell) found in 1 to 10 cells isolated through immunomagnetic enrichment. The assay is an improvement over multiplex PCR and allows efficient detection of rare coding sequences for circulating carcinoma cells in the blood. The methods are useful in profiling of cells isolated from tissues or body fluids and serves as an adjunct to clinical diagnosis of diverse carcinomas including early stage detection and classification of circulating tumor cells. Monitoring of nucleic acid and protein profiles of cells either in conventional or microarray formats, facilitates management of therapeutic intervention including staging, monitoring response to therapy, confirmation of remission and detection of regression.

La présente invention concerne un dosage hautement sensible qui utilise une technique d'amplification amorcée spécifique du gène de bibliothèques d'ARNm issus de cellules rares et de transcrits rares trouvés dans le sang. Ce dosage permet de détecter des ARNm (10 copies /cellule) trouvés dans une à dix cellules isolées via un enrichissement immunomagnétique. Ce dosage constitue une amélioration par rapport à la PCR multiplex et permet de détecter efficacement des séquences de codage rares de cellules de carcinome circulant dans le sang. Ces techniques conviennent pour établir le profil de cellules isolées issues de tissus ou de fluides anatomiques et elles servent d'auxiliaire pour un diagnostic clinique de divers carcinomes, notamment dans la détection au stade précoce et dans la classification des cellules tumorales circulant. La surveillance des profils d'acide nucléique et de protéine de cellules dans des formats soit classiques, soit de jeu ordonné de microéchantillons, facilite la gestion d'intervention thérapeutique comprenant la classification par stades, la surveillance de la réponse à la thérapie, la confirmation de rémission et la détection de régression.
