描述:
Resistin, also known as adipocytespecific secretory factor (ADSF) and found in
inflammatory zone 3 (FIZZ3), is a member of a family of secreted cysteinerich
peptide hormones that also includes Resistinlike molecules RELM alpha, beta,
and gamma. These molecules play important roles in inflammation, glucose
metabolism, and insulin resistance. Mature mouse Resistin is a 12 kDa protein
with an Nterminal αhelical domain and a Cterminal βsandwich domain
that is stabilized by multiple intrachain disulfide bonds. Resistin circulates as
noncovalent trimers and disulfidelinked hexamers, with the trimeric form showing
greater bioactivity. Resistin can also form multimers with RELMβ. Mature mouse
Resistin shares 56% and 72% amino acid (aa) sequence identity with human and rat
Resistin, respectively. It shares 34% 42% aa sequence identity with mouse RELMα, β, and
γ. In rodents, Resistin is expressed by adipocytes and in the pituitaryand arcuate nucleus
of the hypothalamus. It is upregulated during adipogenesis, in obesity, and by insulin or
a high carbohydrate diet. This is in contrast to human Resistin which is produced by
macrophages and monocytes but not by adipocytes. Mouse Resistin induces proinflammatory
molecule production in adipocytes and promotes hepatic gluconeogenesis and insulin
resistance. Human Resistin promotes lipolysis by human and mouse adipocytes, but mouse
Resistin does not promote lipolysis by adipocytes of either species. Both mouse and
human Resistin promote vascular endothelial cell sprouting in vitro and
inflammatory reactions in vivo.
