Using principles from social media to explore cytoskeletal regulatory networks in dividing human cells


Over 100 proteins orchestrate mitotic spindle movements and thereby define the plane of cell division in all cells. How these players jointly steer the spindle towards a predefined position is not clear. To address this, we are undertaking a novel approach of analyzing terabytes of live-cell movies of dividing human cells lacking distinct regulators of spindle function, where abstractly what we are looking at is identifying which players are ‘functionally’ connected with which other players. This is a combinatorial problem, and to address this scalably, this project will adapt and repurpose powerful new computational tools that have been highly successful for large social network data.
