Transforming growth factor beta (TGF beta) immunoreactivity was determined
in endometria from non-drug-therapy and tamoxifen-treated patients. Section
s were scored for pathology and quantity image analysis performed to determ
ine levels of glandular- or fibrosis-associated TGF beta1. Tamoxifen-treate
d patients displayed greater levels of endometrial dysplasia and glandular
hyperplasia, in addition to a statistically significant (P < 0.0001) elevat
ion in gland-associated TGF<beta>1 protein. (C) 2000 Elsevier Science Ltd.
