Why are they there?
Do they locally generate metabolites to regulate chromatin?
Could they become new drug targets or disease biomarkers?

These findings highlight how subcellular localization and moonlighting functions can reshape how we think about metabolism.

Native chromatome profiling reveals hundreds of metabolic enzymes in the nucleus across tissues - Nature Communications Here proteomic chromatome analysis shows metabolic enzymes widely localize to chromatin in cancer in a tissue-specific manner.

New paper out in Nature Communications:

We found >250 metabolic enzymes on chromatin.
Only ~20 had been reported before.
This means hundreds of metabolic enzymes may have unexplored nuclear roles.

Mitochondria-derived nuclear ATP surge protects against confinement-induced proliferation defects - Nature Communications The authors uncover a mechano-metabolic adaptation where confinement induces rapid mitochondrial relocalization to the nuclear periphery, generating localized nuclear ATP surges that support chromatin remodeling, DNA repair, and cell cycle progression.

Earlier this summer we have published this. Looks like a similar localization of mitochondria in the centre of the nucleus: www.nature.com/articles/s41...

Dr. Jane Goodall has passed away. Her groundbreaking work with chimpanzees and her lifelong dedication to conservation changed how we see and care for our planet.

Happy to share the Biodiversity Cell Atlas white paper, out today in @nature.com. We look at the possibilities, challenges, and potential impacts of molecularly mapping cells across the tree of life.

Open questions:
Is nuclear metabolism linked to #aging?
Can we reverse the aging process by restoring nuclear metabolism?
What else besides PIP2?

Our study links nuclear PIP2 metabolism to nucleoli structure, histone modification, and cell cycle progression. This provides evidence that nuclear metabolism oscillations can control cell cycle progression, which, when altered, can induce cell cycle arrest and cell senescence.

4) The aberrant localization of PIP2 in the nucleus/nucleoli and the alteration of the nucleoli structure lead to changes in the accumulation of histone marks. For example, H4K20me1 decreases, which subsequently affects proper cell cycle progression.

3) What happens to cells when we interfere with PIP2 metabolism in the nucleus? In addition to preventing cell cycle progression, the structure of the nucleolus is affected and the localization of PIP2 to the Fibrillarin-labeled nucleoli region is altered.

2) We used our lab's gold standard chromatome protocol to study the oscillation of metabolic enzymes on chromatin during the cell cycle. We identified a correlation between cell cycle progression and PIP2 metabolism on chromatin.

1) By integrating FUCCI reporters and classical proliferation/senescent markers, we identified a population of cells, which we termed G0-senescent, that had never before been identified using FUCCI.

Our initial question was: does the cell cycle control the association of metabolic enzymes with chromatin? The short answer is YES!
We adapted the FUCCI system and extensively characterized U2OS FUCCI using HT-microscopy and FACS.
