[Transforming growth factor-alpha in human lung cancer tissue]
1China-Japan Friendship Hospital, Beijing.
Abstract:
12 cases of human lung cancer tissue were analyzed for the presence of transforming growth factor-alpha with RIA. Histologically 9 were squamous cell carcinoma and 3 were adenocarcinoma. Except one squamous carcinoma, TGF-alpha could be detected in 11 cases. TGF-alpha level was from 0.26 ng to 1.26 ng per gram tissue. There was no significant difference in TGF-alpha level between squamous cell carcinoma and adenocarcinoma. The relationship between TGF-alpha and human lung cancer remains for further study.
