ICYMI: New Online! Functions and therapeutic applications of pseudouridylation

Functions and therapeutic applications of pseudouridylation

Nature Reviews Molecular Cell Biology, Published online: 20 May 2025; doi:10.1038/s41580-025-00852-1Pseudouridine is a long-discovered RNA modification that has lately attracted much renewed interest. This Review discusses the emerging functions of pseudouridine in gene regulation and mitochondrial function, and its therapeutic potential following the successful use of pseudouridylation in SARS-CoV-2 mRNA vaccines.

Well, I live for these moments! A mutation in tRNA-modifying enzyme confuses the ribosome to synthesize aberrant and, most importantly, immunogenic peptides that enhance immune response against tumors! Amazing data in many different layers; from cell biology to clinical research! Congratulations!

Thrilled to share our latest work in Cancer Cell! 🚨 Led by @chenweller, Osnat Bartok, with amazing collaborators @Chrismcginnis, @AnsumanSatpathy, Andreas Schlosser, @EytanRuppin & more, we reveal that impaired translation fidelity enhances anti-tumor immunity!🧵(1/7)

This is a promising study! Looking forward to the era that specific cancers could be prevented like infectious diseases. The more neoantigens we discover, the higher the variability of the vaccines!

It's the hook that matters 🪝 A great study by a good friend @eirinibellou.bsky.social and the pioneering @schuhlab.bsky.social !!! Amazing, truly intuitive images and invaluable insights with clinical perspectives! Congratulations!!!

Why are some chromosomes like #21 in Down syndrome more error-prone in mammalian eggs? 🤔

Our new study in @naturecomms.bsky.social reveals why acrocentric chromosomes often mis-segregate, causing aneuploidy and miscarriages. (1/9)

Our latest work is out in Nature today! Using smFRET, we directly visualized recruitment of the eIF4F complex to the 5' cap of eukaryotic mRNAs and formation of an activated mRNA. Our findings reveal new and surprising roles for each eIF4F component. 1/3 www.nature.com/articles/s41...

These aspects are often overlooked in research. Our effort to design cancer therapeutics should be as delicate and complicated, as cancer and the human body are.

Another paper that shows the significance and therapeutic potential of aberrant translation in cancer. We have much more to learn from the ribosome!

Chemotherapeutic agents and leucine deprivation induce codon-biased aberrant protein production in cancer

Abstract. Messenger RNA (mRNA) translation is a tightly controlled process frequently deregulated in cancer. Key to this deregulation are transfer RNAs (tR

The ribosome decodes, catalyzes and moves. Everything you need to know about the cellular machine that defines life itself, described by one of the founding fathers of ribosome biology.

The ribosome comes to life

The ribosome is an ancient molecular machine that coverts the genetic information carried by mRNA into protein, a crucial step in linking genotype to phenotype. This review discusses landmark advances...
