My “Eureka” moment. A cure for cancer.

... a growth factor receptor blocker / inhibitor drug which partially binds to target cell growth factor receptors, not bound accurately enough to activate the cell growth factor receptor function, but sufficiently bound to block growth factor binding to the growth factor receptors. Whatever the ...

cAMP 2nd Messenger Pathway and Experiments

... the protein extract from the cyc+ cells was treated to inactiate adenylyl cyclase activity only. This adenylyl cyclase activity was definitely inactivated. Stimulating hormone, ATP, GTP, and Mg2+ were included in mixture. Mixture was: cell membranes from the cyc- cells, protein extracts from ...
