RÉSUMÉ
Objective To evaluate the inhibiting effect of antisense vascular smooth muscle alpha adenovirus vector on tubular epithelial myofibroblast transdifferentiation induced by TGF-?1.Methods The pAdanti-?-SMA was constructed and identified.The ?-SMA expression in tubular epithelial cells(TEC) was detected by immunofluorescence and Western blot.Five groups were designed as control(A),TEC transfected by 2 ?l pAdanti-?-SMA(B),TEC induced by TGF-?1(C),TEC induced by TGF-?1 and transfected by 2 ?l pAdanti-?-SMA(D),TEC induced by TGF-?1 and transfected by 10 ?l pAdanti-?-SMA(E).Results The pAdanti-?-SMA was successfully constructed.The expression of ?-SMA in TEC induced by TGF-?1 was inhibited by pAdanti-?-SMA.Conclusion Tubular epithelial myofibroblast transdifferentiation can be inhibited by pAdanti-?-SMA.
