The goal of the Targeted Therapeutics in Cancer lab is to kill cancer cells. Our research interests include mitochondrial apoptosis, epigenetics, and metabolism.

1/New paper from Zheng Wu, Phong Nguyen et al. @cri-utsw.bsky.social shows how cells balance the two pathways that produce purine nucleotides: de novo purine biosynthesis (DNPB) and purine salvage. The surprising mechanism involves NUDT5, a Nudix hydrolase

NUDT5 regulates purine metabolism and thiopurine sensitivity by interacting with PPAT
Cells generate purine nucleotides through de novo purine biosynthesis (DNPB) and purine salvage. Purine salvage represses DNPB to prevent excessive purine nucleotide synthesis through mechanisms that ...

A fantastic viewpoint by @frezzalab.bsky.social network.febs.org/posts/thinki...

It reminds me of the lampost-and-key analogy described in this article by Michael Yaffe www.science.org/doi/10.1126/....
The goal is to understand network-based signalling.

Cells swapping their #mitochondria - this sounded like science fiction 🧪 when the first studies started coming out!

But now this has been observed in #cancer, #yeast, #molluscs, and under normal physiology - as a way to regulate energy demands, metabolism, cell fate & much more - true #powerhouses!
Cells are swapping their mitochondria. What does this mean for our health?
Researchers are studying why the energy factories are moving between cells and whether the process can be harnessed to treat cancer and other diseases.

Inhibition of HDAC6 alters fumarate hydratase activity and mitochondrial structure - Nature Communications
Here they show that HDAC6 inhibition regulates fumarate hydratase (FH), disrupts mitochondria, increases fumarate, and causes cancer cell death. This suggests that HDAC6 inhibition could be a strategy...

An interesting paper just published in Nature on HDAC6 as a valine sensor:
rdcu.be/d1waX
Human HDAC6 senses valine abundancy to regulate DNA damage
Nature - The histone deacetylase HDAC6 is a sensor of valine levels, and the abundance of valine in cells regulates DNA damage and cell homeostasis functions.
