 Origin Outbred Wistar rats were transferred from the BioBreeding Laboratories in Ottawa, Canada, to the Institute of Pathophysiology (formerly the Institute of Diabetes Gerhardt Katsch) in Karlsburg, Germany in 1981. By selective breeding of RT1<sup><i>a</i></sup> or RT1<sup><i>u</i></sup> homozygous from the outbred Wistar rats, two inbred lines were generated as WOK.1A (Wistar Ottawa Karlsburg RT1<sup><i>a</i></sup>) or WOK.1W respectively (Kov&#225;cs, 1997). Wistar Ottawa Karlsburg W. (Sep 16, 2010) 
 Strain Characteristics WOKW rats and BB/OK rats were originated from the same colony of Wistar rat and both strains possess RT1<i>u</i> haplotype (Kov&#225;cs, 1997). WOKW rats develop polygenic inherited metabolic syndrome resembling human disorder such as obesity, dyslipidemia, impaired glucose tolerance (IGT), hyperinsulinemia and hyperleptinemia (Kov&#225;cs, 1997; Kov&#225;cs, 2000; van den Brandt, 2000; van den Brandt, 2002). By breeding analysis of disease-prone WOKW and disease-resistant DA rats, several QTLs associated with metabolic syndrome were mapped (Kov&#225;cs, 2000; Kl&#246;ting, 2001; Baguhl, 2009). Some of them were sex-specific. (Sep 16, 2010)
