] AIM: To investigate the expression of the urotensin Ⅱ (UⅡ) receptor GPR14 in the aorta of apoE knockout mouse. METHODS: The expression of GPR14 in the aorta of apoE knockout C57BL/6J mice at various ages (18 weeks, 28 weeks, and 38 weeks old, respectively) was determined with competitive RT-PCR. A binding assay of [ 125 I]-UⅡ on the aortic tissue was also performed in 28 weeks group. RESULTS: We found significant upregulation of GPR14 mRNA at all three ages. Compared with wild type group at the same age, the GPR14 mRNA level in apoE knockout mice increased 54.2% in 18 week group (P
ABSTRACT
5 fold) were noted.Six significant differential proteins in gel were identified by LTQ-ESI,e.g.endoplasmin precursor,acidic leucin-rich nuclear phosphoprotein 32 family member A,serotransferrin precursor,stress-70 protein precursor,fibronectin precursor,complement C3 precursor,fibrinogen gamma polypeptide.CONCLUSION: The protein profile of apoE-/-/LDLR-/-mouse liver exhibits significant difference compared to that of WT mice.The results imply that lipid metabolism relative polygenetic mutation contributes to the alteration of mouse liver protein expression profile,especially that lipid metabolism related perhaps participates in dysfunction in lipid metabolism during atherogenesis.
