With the advance in the molecular understanding of cancers and prolife
rative disorders new approaches to managing these diseases may become
feasible. It has been recognized that a key feature of these diseases
is the pathological alteration in the molecular machineries of signall
ing pathways. This recognition which began to emerge in the early 1980
s induced us to explore the possibility of targetting the aberrant sig
nalling pathways for disease therapy. I now present evidence for the v
alidity of the approach.
