Hallmarks of Cancer: New Dimensions. Ol@
YSk d
The hallmarks of cancer conceptualization is a heuristic tool for distilling the vast A&0sD}I\K
complexity of cancer phenotypes and genotypes into a provisional set of underly- T+/Gz'
ing principles. As knowledge of cancer mechanisms has progressed, other facets of the disease have j&?NE1D>I
emerged as potential refinements. Herein, the prospect is raised that phenotypic plasticity and dis-
`Uw^,r
rupted differentiation is a discrete hallmark capability, and that nonmutational epigenetic reprogram- ffyKAZ{]po
ming and polymorphic microbiomes both constitute distinctive enabling characteristics that facilitate BT+ws@|[
the acquisition of hallmark capabilities. Additionally, senescent cells, of varying origins, may be added {4{ACp
to the roster of functionally important cell types in the tumor microenvironment.
