Evaluation of antiproliferative activities..", it says:
Quote:
The antiproliferative activities on tumoral cells, namely, human breast cancer (MCF-7 and MDA-MB-231), hepatoma (HepG2) and myeloid leukemia (HL-60), of ethanolic extracts from two species of Ganoderma, G. lucidum and G. sinense, were investigated. Though both extracts had certain antiproliferative activities, their chemical characteristics, including nucleosides, triterpenoids and sterols, were significantly different. Their effects on MDA-MB-231 cells were further studied...

I guess would have to see the net effect on MCF7 or other ER+ BC cell lines. The furher study with 231 cells is with ER- cell line.
The Silva study abstract doesn't specify ER status of the cell line. But I believe Silva was the researcher I contacted who got into the cultivation/environment influence on Ganoderma luciderm effects.
