Aberrant constitutive activation of receptor-mediated downstream signalling plays
an active role in the deregulation of cell cycle control. The mitotic spindle
checkpoint is important in preventing abnormal mitotic cell cycle with chromosome
missegregation from achieving neoplastic aneuploidy. However, mechanisms coupling
receptor-mediated signalling to mitotic spindle checkpoint regulation remain
unclear. Pellino 1 is a receptor signal-responsive E3 ubiquitin ligase, and the
application of certain receptor-mediated signalling regulates the expression and
activity of Pellino 1. In the present study, Pellino 1 expression induced
extensive chromosome aneuploidy and allowed abnormal mitotic cells to adapt and
become aneuploid in vitro and in vivo. Pellino 1 directly interacted with BubR1,
a key component of mitotic spindle checkpoint, in a mitotic cell-cycle dependent
manner, and down-regulated the stability of BubR1 by ubiquitination-mediated
degradation and induced mitotic dysfunction. In summary, Pellino 1 expression
acts as an inhibitory signal of the homeostatic regulation of mitotic cell cycle
and checkpoint, and thus contributes to the initiation and progression of
neoplastic chromosome aneuploidy.
