Abstract:
:It has long-been accepted that normal somatic cells have intrinsic mechanisms that limit their proliferative lifespan. Recent work has now challenged this view by demonstrating that extrinsic factors might be determining proliferative potential.

杂志文章abstract::The Ndc80 complex (Ndc80, Nuf2, Spc24 and Spc25) is a highly conserved kinetochore protein essential for end-on anchorage to spindle microtubule plus ends and for force generation coupled to plus-end polymerization and depolymerization. Spc24/Spc25 at one end of the Ndc80 complex binds the kinetochore. The N-terminal ...
