Predicting the translation efficiency of messenger RNA in mammalian cells
The degree to which translational control is specified by mRNA sequence is poorly understood in mammalian cells. Here, we constructed and leveraged a compendium of 3,819 ribosomal profiling datasets, ...

Chromosome mis-segregation triggers cell cycle arrest through a mechanosensitive nuclear envelope checkpoint - Nature Cell Biology
Hervé, Scelfo et al. show that chromosome mis-segregation induces mTORC2- and ATR-mediated p53 activation through a mechanosensitive checkpoint at the nuclear envelope triggered by altered heterochrom...

How do 250k regulatory sequences coordinate 15k genes in mammalian development? Just out: A genomic evidence board to decode the chaos by mapping enhancer-gene interactions across embryonic mouse tissues New resource with Miao Yu, Ming Hu, Bing Ren, and more. www.nature.com/articles/s41...
A modified version of the "Pepe Silvia" meme from It's Always Sunny in Philadelphia. A frantic man points at a chaotic evidence board covered with a sketch of a mouse embryo,  enhancers, and a gene, connected with tangled lines. He looks intense, as if he's trying to explain a complex, interconnected system. He says "Listen, listen. You don't understand! Those enhancers are everywhere! It's all connected!"

My first first-author paper was published this morning! Did you know eye lenses grow in layers throughout life and can be analyzed to study movement and foraging ecology. But eye lenses differ in bio molecular composition across fish taxa, especially for sharks! 🧪🌎🦑 link.springer.com/article/10.1...

"We report that numerous “miRNAs” previously reported in EMT and cancer contexts are not incorporated into RISC and are not capable of endogenously silencing target genes, despite the fact that hundreds of publications in the cancer field describe their roles" www.biorxiv.org/content/10.1...

🧪 #RNASky #RNABiology Our paper is now on bioRxiv. A short thread. This is the work of 2 former students (& me) - Sandipan dasgupta and Anand Ravi The whole project originated more than a decade ago during my postdoc days. I found that mRNAs can transfer between mammalian cells, not by exosomes>>

What are the consequences of excessive RNA production? We found that MYC hyper activation that increases RNA synthesis, also accelerates RNA decay, resulting in a new type of oncogenic stress- RNA catabolic stress. Happy to share this work was featured on the cover. aacrjournals.org/cancerdiscov...
