-
signaling molecules called tyrosine kinases
-
were to creating intracellular signals.
-
Well, it turns out that certain kinds of tumors
-
you use a special tyrosine kinase called BCRABL
-
and that that tyrosine kinase can be inhibited by a drug
-
that was designed to inhibit it, called Gleevec.
-
Now, this is one of the first examples of
-
what's called rational drug design,
-
in that biologists have
-
identified this particular tyrosine kinase.
-
They knew it was involved in
-
signaling inside certain kinds of cancers,
