Expression data from wild-type and HMGN1 knockout mice injected with N-nitrosodiethylamine


ABSTRACT: HMGN1 contributes to the shortened latency of liver tumorigenesis by changing a chromatin structure and expression of relevant genes To assess the molecular mechanisms underlying accelerated tumor development in Hmgn1-/- mice, we performed the gene expression profiling of liver cells at early stages Expression profiles has been compared between Hmgn1+/+ and Hmgn1-/- mice livers at 4 weeks after birth and at 12 weeks after DEN or saline (control) injection at 4 weeks

<h4>Unlabelled</h4>We report that HMGN1, a nucleosome-binding protein that affects chromatin structure and function, affects the growth of N-nitrosodiethylamine (DEN)-induced liver tumors. Following a single DEN injection at 2 weeks of age, Hmgn1(tm1/tm1) mice, lacking the nucleosome-binding domain of HMGN1, had earlier signs of liver tumorigenesis than their Hmgn1(+/+) littermates. Detailed gene expression profiling revealed significant differences between DEN-injected and control saline-inject  ...[more]
