  • Title: [Cold adaptation and changes in peroxisome enzyme in various organs of the rat].
    Author: Locci-Cubeddu T, Cizza G, Formichi R, Marcassa C, Bergamini E.
    Journal: Boll Soc Ital Biol Sper; 1982 Aug 30; 58(16):1032-6. PubMed ID: 6128006.
    Abstract:
    In the rat brown fat peroxisomes - thermogenetic organules - an peroxisomal enzyme activities undergo remarkable changes during the adaptation to cold of the animals (see 3). In this paper was show that changes of peroxisomal enzyme activities occur also in liver and kidney during cold-adaptation. Catalase, L-hydroxyacid oxidase, uricase and D-aminoacid oxidase (DAO) were assayed as in (6). During cold-adaptation, the activity of the former three enzymes (Table 2) increases with the weight of the organs (Table 1) whereas that of DAO exhibits a much larger increase (Table 3). Results are discussed with regard to the contribution of the liver to non-shivering thermogenesis.
