Special thanks to Adam Palmer's lab, Matt Vander Heiden's lab, Omer Yilmaz's lab, and the folks at Genentech, all of whom were instrumental in this 5-FU story about RNA damage! Collaborative science is always the best!.

Thrilled to share our latest story on 5-FU inducing RNA damage during ribosome biogenesis - The whole thing started when Karl and Jung-Kuei were trying to figure out hiow limiting dNTPS skewed DNA repair. Never thought it would be RNA and tge ribosome!.

5-fluorouracil’s utility in cancer treatment has been attributed to inducing dNTP imbalance and DNA damage in cancer cells. Here, Chen et al. demonstrate that 5-FU’s efficacy results instead from RNA...

Thrilled to share this latest work led by Xiao-Kang Lun in Peng Yin's lab and Xueyang Yu in mine. Finally, single cell signaling can begin to rival single cell RNA-Seq, using CyTOF, phospho-antibodies and ACE amplification.

This is a really important thread from Lior Pachter about the mathematical underpinnings of scRNAseq.

Excited to share our latest story - JNK and Erk MAPK signaling controls senescence from damaged replication forks, and at later times drives the SASP. Means MEK inhibitors with topoisomerase chemo likely to be a bad combo!.

In the bioRxiv paper, we find that 5-FU shows no synergy at the cellular level with the DNA damaging drugs oxaliplatin or irinotecan - the combination given for GI cancer Rx. Instead, ribosome and tRNA biogenesis is impaired, driving an apoptotic signal that does not require p53.

RNA Damage? Happy to share Jung-Kuei Chen and Karl Merrick and @LabYaffe preprint that reports the major mechanism of 5-FU action in clinically relevant cancer treatment is through damage to structured RNAs.

5-fluorouracil (5-FU) is a successful and broadly used anti-cancer therapeutic. A major mechanism of action of 5-FU is thought to be through thymidylate synthase (TYMS) inhibition resulting in dTTP...

Fork reversal requires the RAD51 recombinase to overcome the CMG helicase, which remains bound to the stalled fork.
