Cloning and expression of a novel mouse somatostatin receptor (SSTR2B).

abstract：:We employed cDNA representational difference analysis to identify new genes that are upregulated by 2,3,7,8-tetrachlorodibenzo-p-dioxin (TCDD) in a human hepatoblastoma cell line HepG2. We isolated several TCDD-responsive cDNAs. Sequence analysis revealed that one of them encodes E16/CD98LC/hLAT1, an integral membrane...
