Mild replication stress causes premature centriole disengagement via a sub-critical Plk1 activity under the control of ATR-Chk1.

A tight synchrony between the DNA and centrosome cycle is essential for genomic integrity. Centriole disengagement, which licenses centrosomes for duplication, occurs normally during mitotic exit. We recently demonstrated that mild DNA replication stress typically seen in cancer cells causes premature centriole disengagement in untransformed mitotic human cells, leading to transient multipolar spindles that favour chromosome missegregation.

PLK1 controls centriole distal appendage formation and centrobin removal via independent pathways.

Centrioles are central structural elements of centrosomes and cilia. In human cells, daughter centrioles are assembled adjacent to existing centrioles in S-phase and reach their full functionality with the formation of distal and subdistal appendages one-and-a-half cell cycles later, as they exit their second mitosis. Current models postulate that the centriolar protein centrobin acts as placeholder for distal appendage proteins that must be removed to complete distal appendage formation.

Cost Effectiveness of Sacral Neuromodulation and OnabotulinumtoxinA in Managing Refractory Idiopathic Overactive Bladder.

Little information from clinical and modelled studies are available on cost effectiveness of OnabotulinumtoxinA and SNM for the treatment of idiopathic overactive bladder. We aimed to summarize the evidence in this regard from different healthcare systems. Seven studies from 5 countries were reviewed.
