HIC1 ( hypermethylated in cancer 1 ) is a tumor suppressor gene located on chromosome 17p13.3, a region frequently hypermethylated or deleted in human neoplasias. In mouse, Hic1 is essential for embryonic development and exerts an antitumor role in adult animals. Since Hic1 ‐deficient mice die perinatally, we generated a conditional Hic1 null allele by flanking the Hic1 ‐coding region by lox P sites. When crossed to animals expressing Cre recombinase in a cell‐specific manner, the Hic1 conditional mice will provide new insights into the function of Hic1 in developing and mature tissues. Additionally, we used gene targeting to replace sequence‐encoding amino acids 186–893 of Hic1 by citrine fluorescent protein cDNA. We demonstrate that the distribution of Hic1‐citrine fusion polypeptide corresponds to the expression pattern of wild‐type Hic1 . Consequently, Hic1‐citrine “reporter” mice can be used to monitor the activity of the Hic1 locus using citrine fluorescence. genesis 49:142‐151, 2011. © 2011 Wiley‐Liss, Inc.
