We invite you to our next SYSBIO OPEN JOURNAL CLUB, to be held on
Tuesday 01/10/19 from 15:30 TO 17:00 H. 

We will discuss the following preprint:

ABSTRACT:To divide, most animal cells drastically change shape and round
up against extracellular confinement. Mitotic cells facilitate this
process by generating intracellular pressure, which the contractile
actomyosin cortex directs into shape. Here, we introduce a genome-scale
microcantilever- and RNAi-based approach to phenotype the contribution
of > 1000 genes to the rounding of single mitotic cells against
confinement. Our screen analyzes the rounding force, pressure and volume
of mitotic cells and localizes selected proteins. We identify 49 genes
relevant for mitotic rounding, a large portion of which have not
previously been linked to mitosis or cell mechanics. Among these,
depleting the endoplasmic reticulum-localized protein FAM134A impairs
mitotic progression by affecting metaphase plate alignment and pressure
generation by delocalizing cortical myosin II. Furthermore, silencing
the DJ-1 gene uncovers a link between mitochondria-associated
Parkinson's disease and mitotic pressure. We conclude that mechanical
phenotyping is a powerful approach to study the mechanisms governing
cell shape.
