Cyclic AMP response element binding protein binding protein (CBP), a nuclear transcriptional coactivator protein, is an important component of the cAMP signal transduction pathway. In this study, we systematically analyzed the pattern and frequency of CBP gene alterations in esophageal squamous cell carcinoma (ESCC) samples from Linzhou (Linxian), China. Experimental Design: Using microsatellite markers D16S475, D16S2622, and D16S523 within the chromosome 16p13.3 locus flanking the CBP gene, we observed loss of heterozygosity (LOH), microsatellite instability (MSI), or homozygous deletion in 16 of 26 ESCC samples. Additional ESCC samples were analyzed using different sets of microsatellite markers (CS1-CS5) within the introns or in close proximity to the 3' end of the CBP gene.
