The accumulated evidence supports the expression of estrogen receptor
variants at both the mRNA and protein levels. The relative level of ex
pression of some estrogen receptor variant mRNAs and possibly progeste
rone receptor variant mRNAs is altered during breast tumorigenesis and
breast cancer progression. The altered expression of estrogen recepto
r variants may effect estrogen signal transduction as well as the inte
rpretation of assays where the estimation of estrogen receptor levels
is used as a guide to treatment strategies and prognosis. (C) 1998 Els
