Hallmarks of Cancer: New Dimensions. zHX7%x,Cq
The hallmarks of cancer conceptualization is a heuristic tool for distilling the vast mhgvN-? "h
complexity of cancer phenotypes and genotypes into a provisional set of underly- I]-"Tw
ing principles. As knowledge of cancer mechanisms has progressed, other facets of the disease have sh/4ui{
emerged as potential refinements. Herein, the prospect is raised that phenotypic plasticity and dis- 'j9x(T1M1
rupted differentiation is a discrete hallmark capability, and that nonmutational epigenetic reprogram- MMy\u) 4
ming and polymorphic microbiomes both constitute distinctive enabling characteristics that facilitate ++!'6!l
the acquisition of hallmark capabilities. Additionally, senescent cells, of varying origins, may be added <xlyk/
to the roster of functionally important cell types in the tumor microenvironment.
