摘要: Guanylyl cyclase C is a sensitive and specific biomarker for metastatic colorectal cancer. A variant of the guanylyl transcript was identified that possesses 142-bp deletion at 3" end exon 1 reflecting alternative splicing mRNA, introducing shift in open reading frame prevents translation C-related product. This human intestine colon carcinomas, but not extraintestinal tissues or tumors. These studies demonstrate GCC splice contribute to pool transcripts detected by RT-PCR tissues. They indicate primers amplify regions downstream from are required assess full complement (GCC + GCCvar) body fluids staging postoperative surveillance patients with
