title: Gene expression profiling reveals an inflammatory process in the anx/anx mutant mice.
abstract: Anorexia (anx) is a recessive mutation that causes lethal starvation in homozygous mice. Studies of anx/anx mice hypothalamus have shown abnormalities in the orexigenic (NPY/AGRP neurons) and the anorexigenic (POMC/CART neurons) pathways. By gene expression profiling using cDNA and oligonucleotide microarrays, we have shown that a surexpression of genes involved in inflammatory process occurred in anx mice hypothalamus. This inflammatory process could be the cause of the anorexia phenotype observed in these mice.
