Cell size and the cell cycle are intrinsically coupled and abnormal increases in cell size are associated with senescence and permanent cell cycle arrest. The mechanism by which overgrowth primes cells to withdraw from the cell cycle remains unknown. We investigate this here using CDK4/6 inhibito...
The evolution of new enzymatic functions is constrained and guided by the architecture of an organism’s metabolic and regulatory networks and environmental constraints. Here, we identify a kinase that has evolved from pyruvate phosphate dikinase. Through biochemical and systems-lev...
To elucidate the function of oxidative phosphorylation (OxPhos) during B-cell differentiation we employ CD23Cre-driven expression of the dominant-negative K320E mutant of the mitochondrial helicase Twinkle (DNT). DNT-expression depletes mitochondrial DNA during B cell maturation, reduces the abun...
Macrophage-derived foam cell plays a pivotal role in the plaque formation and rupture during the progression of atherosclerosis. Foam cells are destined to divergent cell fate and functions in response to external stimuli based on their internal states, which however is hidden in the traditional ...
