Disease relevance of PSMD5

  • This interaction is demonstrated by the different susceptibility of Osborne-Mendel (OM) and S5B/P1 rat strains to obesity when offered a high-fat diet [1].
 

High impact information on PSMD5

  • Immunohistochemical studies demonstrated that Osborne-Mendel rats eating a chow diet had an increased number of mu opioid receptors in the arcuate nucleus when compared to S5B/Pl rats [2].
  • These immunohistochemical findings were supported by Real Time-PCR which demonstrated that the mRNA level of mu opioid receptors was also increased in the hypothalamus of Osborne-Mendel rats compared to S5B/Pl rats [2].
  • The same doses of DAMGO switched the diet preference of S5B/Pl rats to high fat but did not significantly increase food intake [2].
  • In satiated S5B rats, GHRP-2 stimulated intake of the LF diet in a dose dependent manner but did not affect the intake of the HF diet [3].
  • In addition, a differential regulation of ghrelin gene expression between OM and S5B rats may be important in their differential sensitivity to HF diet-induced obesity [3].
 

Analytical, diagnostic and therapeutic context of PSMD5

  • We have investigated these hypotheses in two strains of rat, the Osborne-Mendel (OM) rat that prefers diets high in fat and is sensitive to dietary obesity and the S5B/P1 (S5B) rat that prefers a low fat diet and is resistant to high fat diet induced obesity [3].
