Endometrial carcinoma: association of steroid hormone receptor expression with low angiogenesis and bcl-2 expression
Sivridis, E.; Giatromanolaki, A.; Koukourakis, M.; Anastasiadis, P. (2001)In endometrial tissues, malignant change may be accompanied by a loss of hormone dependence which is, usually, reflected in a parallel loss of oestrogen and progesterone receptors (ER and PR). In this study, the steroid ... -
