RNA Pol II inhibition activates cell death independently from the loss of transcription When RNA polymerase II (RNA Pol II) is inhibited, the inhibition is sensed and signaled to mitochondria, leading to programmed cell death independently of the loss of RNA Pol II transcription activity...

I’m excited to highlight our latest paper, just published in Cell πŸŽ‰

We report the existence of a previously uncharacterized signaling pathway that is responsible for activating cell death upon loss of gene expression.

Transient APC/C inactivation by mTOR boosts glycolysis during cell cycle entry - Nature APC/C activity is transiently inhibited to generate a pulse of glycolysis that is required for mammalian cell cycle entry.

Check out our new paper by postdoc Debasish Paul, out now in @Nature.com. Cells need a boost of energy to jumpstart the cell cycle, but how can this happen while the APC/C is inhibiting glycolysis? We found cells solve this paradox through a highly dynamic mechanism.
