Information from provider
| Provider | Leena Alhonen |
| Provider affiliation | Laboratory Animal Center, University of Eastern Finland |
| Genetic information | Mice have disrupted spermidine/spermine N1-acetyltransferase (SSAT) gene resulting in lost capability to catabolize polyamines via acetylation pathway. Endogenous X chromosomal mouse spermidine/spermine N1-acetyltransferase gene was disrupted by replacing part of exon 1 with neo gene. |
| Phenotypic information | Largely normal, insulin resistance at old age, altered susceptibility to ischemia-reperfusion or endotoxin induced tissue injury. These mice are an excellent counterpart to mice with SSAT overexpression. |
| Breeding history | Targeting in RW-4 ES cells injected into C57BL/6J blastocysts, mice later backcrossed to inbred C57BL/6 for more than 20 generations. Maintenance in C57BL/5JOlaHsd strain. |
