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...
MYC Induces Oncogenic Stress through RNA Decay and Ribonucleotide Catabolism in Breast Cancer
MYC induces a previously uncharacterized type of oncogenic stress by increasing global RNA degradation and downstream ribonucleotide catabolism and ROS accumulation; this catabolic vulnerability can b...

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! 🧪🌎🦑

"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"

🧪 #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>>
