A quantitative hypothesis for cancer genesis and progression-the endogenous
molecular-cellular network hypothesis, intended to include both genetic and
epigenetic causes of cancer-has been proposed recently. Using this hypothesis,
here we address the molecular basis for maintaining normal liver and
hepatocellular carcinoma (HCC), and the potential strategy to cure or relieve
HCC. First, we elaborate the basic assumptions of the hypothesis and establish a
core working network of HCC according to the hypothesis. Second, we quantify the
working network by a nonlinear dynamical system. We show that the working network
reproduces the main known features of normal liver and HCC at both the modular
and molecular levels. Lastly, the validated working network reveals that (i)
specific positive feedback loops are responsible for the maintenance of normal
liver and HCC; (ii) inhibiting proliferation and inflammation-related positive
feedback loops and simultaneously inducing a liver-specific positive feedback
loop is predicated as a potential strategy to cure or relieve HCC; and (iii) the
genesis and regression of HCC are asymmetric. In light of the characteristic
properties of the nonlinear dynamical system, we demonstrate that positive
feedback loops must exist as a simple and general molecular basis for the
maintenance of heritable phenotypes, such as normal liver and HCC, and regulating
the positive feedback loops directly or indirectly provides potential strategies
to cure or relieve HCC.
