Co-regulated expression of HAND2 and DEIN by a bidirectional promoter with asymmetrical activity in neuroblastoma

Abstract excerpt

BACKGROUND: HAND2, a key regulator for the development of the sympathetic nervous system, is located on chromosome 4q33 in a head-to-head orientation with DEIN, a recently identified novel gene with stage specific expression in primary neuroblastoma (NB). Both genes are expressed in primary NB as well as most NB cell lines and are separated by a genomic sequence of 228 bp. The similar expression profile of both...
