Over Expression and Its Significance of Bid Protein in Keloid / 中国微创外科杂志

ABSTRACT

0.05),there were more apoptosis-starting cells found in normal skin(1738.33?348.89/mm2)than in keloid(891.67?395.00/mm2)(t=-5.565,P=0.000).The number of positive stained fibroblast cells in dermis significantly increased in keloid group(911.67?323.61/mm2),compared with that in normal skin group(220.00?80.00/mm2)(t=7.188,P=0.000).This result that the protein expression level of Bid was higher in keloid(0.46?0.08)than that in normal skin tissue(0.02?0.01)(t=18.905,P=0.000)was proven by western blotting test.Conclusions The number of apoptosis-starting cells in epidermis of normal skin is more than that in keloid.Bid protein in dermis of keloid is over expressed.
