But, at the same time, were learning how this product may work. Peter Nelson, whos a medical oncologist at the Fred Hutchinson Cancer Center in Seattle is looking at the very genes that are regulated by the constituents of PC SPES. Here hes doing an in vitro assay where hes growing prostate cancer cells, the LNCaP cell line, in the absence or presence of an extract of PC SPES, extracting RNA from that, and binding that RNA to a gene micro array and asking what genes are up regulated and what genes are down regulated. Hes already identified a couple of dozen genes, many of which are outside the androgen and estrogenic dependent pathway that shows that theres a broader range of activity than mere phytoestrogens.
