Abstract

OBJECTIVE:

To probe into periostin's role in the pathological mechanism of hyperplasic scars, by examining the expression of periostin in hyperplasic scar tissues. To investigate the correlations between periostin and TGF-beta1, TGF-beta R I, TGF-beta R II.

METHODS:

RT-PCR was used to assess the mRNA expression levels of TGF-beta1, TGF-beta R I, TGF-beta R II in three kinds of tissues, which are keloid (K), hypertrophic scar (HS) and normal skin (SK). The protein expression of periostin was measured with Western blotting.

RESULTS:

The mRNA level of periostin in K was higher than that in SK. The mRNA expression of TGF-beta1 in K was higher than that in HS and SK. The mRNA level of TGF-beta R I in K was higher than that in HS and SK. The significances above all was at P < 0.01. The protein expression level of periostin in HS increased, compared with that in SK (P < 0.05). Periostin was related to TGF-beta1 positively (P <0.01).

CONCLUSIONS:

The periostin's expression is increased in keloids. Periostin is a cicatrix specific gene. Periostin appears to play an important role in the formation of keloids, which is related to TGF-beta1 closely.
