To investigate the regulation of mouse L-histidine decarboxylase (HDC) gene expression, we isolated genomic DNA clones encoding HDC. ... In this report we have analysed the mouse HDC gene structure and the process of DNA methylation in the context of cell-type specific and inducible gene expression.

To investigate the regulation of mouse L-histidine decarboxylase (HDC) gene expression, we isolated genomic DNA clones encoding HDC. Structural analysis revealed that the mouse HDC gene was composed of 12 exons, spanning ~24 kb. Northern blotting analysis indicated that, among the cell lines examined, a high level of...
