Expression of SPARC in smooth muscle tissue of ob/ob mice and its clinical significance / 中国基层医药

ABSTRACT

Objective To investigate the secreted protein acidic and rich in cysteine (SPARC) expression in the smooth muscle tissue of ob/ob mice.Methods Study timeFebruary 2017 to June 2017.Six ob/ob mice and 6 littermates aged 10 weeks were selected for the trial.The mesenteric artery smooth muscle tissues were collected.qRT -PCR was used to detect SPARC mRNA expression in smooth muscle tissue.The protein expression of SPARC was assayed by Western blot.Results The SPARC mRNA [(1.73 ± 0.65)] and protein [(1.73 ± 0.65)] in smooth muscle tissue of ob/ob mice presented higher expression compared with those in the littermates [(1.00 ± 0.31),(1.00 ± 0.33),t =8.437,5.533,all P ＜ 0.05].Conclusion The higher expression of SPARC in smooth muscles tissue of ob/ob mice may be involved in diabetes combined with atherosclerosis.
