Abstract:
Objective To study the relation between the expression of P130 Crk-associated substrate (P130Cas),phosphatase and tensin homolog (PTEN)and the epithelial-mesenchymal transition (EMT) of skin scar carcinoma.Methods Tissues of skin scar carcinoma,scar and normal skin were collected from 8 patients who were pathologically diagnosed as skin scar carcinoma with high differentiated squamous cell carcinoma.The expression of PTEN,P130Cas,E-cadherin and Vimentin in normal skin,skin scar and skin scar carcinoma tissues were detected by immunohistochemical method of S-P.Results The expression of PTEN,P130Cas and E-cadherin in normal skin,scar and skin scar carcinoma tissues were all significantly different (P ＜ 0.05).The expression of Vimentin in skin scar carcinoma tissues were significantly increased than that in normal skin and skin scar tissues,but there was no statistically significance difference between skin scar tissues and normal skin (P ＞ 0.05).The expression of PTEN in skin scar carcinoma tissues was negatively correlated with P130Cas (r =-0.78,P =0.023) and positively correlated with E-cadherin (r =0.83,P =0.011),but there were no correlation between PTEN and Vimentin (P ＞ 0.05);The expressions of P130Cas in skin scar carcinoma tissues was negatively correlated with Ecadherin (r =-0.74,P =0.035),but there were no statistically significant correlation between P130Cas and Vimentin (P＞0.05).Conclusions Both PTEN and P130Cas involved in the EMT process of skin scar carcinoma and may be an important mechanism in scar carcinogenesis.
