To accelerate #mRNA vaccine and therapy research, we're excited to share our end-to-end protocol for mRNA design, synthesis and encapsulation in @natprot.nature.com. Protocol development led by @laura-leighton.bsky.social, Natasha Chaudhary and Tim [email protected] rdcu.be/eqiF1

Today, a huge milestone for personalised #mRNA therapeutics for inherited disease! A baby with an ultra-rare mitochondrial metabolic disease was treated at UPenn with an mRNA-encoded gene-corrector. The mRNA was made to treat a single individual in just 7 months! www.nejm.org/doi/full/10....

Systemic mRNA-LNP delivery beyond the liver? Check out our recent paper demonstrating cell-specific mRNA-LNP delivery using PEG- and target cell-specific antibodies. This approach can customised to any target cell-type with off-the-shelf mRNA-LNPs. 1/ sciencedirect.com/science/arti...

Exited to share our latest preprint! mRNA-LNPs are efficiently delivered to healthy livers, but what about liver tumours? Our postdoc @laura-leighton.bsky.social found liver tumours efficiently take up mRNA, enabling next generation mRNA-LNP cancer therapeutics. www.biorxiv.org/content/10.1...

Calling on #ONT #Nanopore #sequencing experts: when sequencing through a stretch of 120nt dA using a DNA plasmid kit (outsourced in our case), what should one expect as average length in the output? The loss we are seeing is a bit extreme #RNAsky

#mRNA meets Tardigrades! Delivery of an mRNA encoding a protein from the famously tough animal can protect healthy tissue from damaging radiation. Very creative! #RNAsky www.nature.com/articles/s41...

Not the best weather forecast for Brisbane 😬

Preach!

Interested in undertaking a PhD in the transformative field #mRNA cancer vaccines? I have an earmarked #PhD scholarship available for an outstanding domestic student to join our team at UQ and @basemrna.bsky.social. If this sounds like you, get in touch. study.uq.edu.au/study-option...

New #mRNA cap structures get you more bang (protein) for your buck! Nice new research from @jmcoller.bsky.social in collaboration with Trilink shows the CleanCap M6 analogue inhibits decapping and substantially increases protein expression in vivo. www.cell.com/molecular-th...

Wow this is super cool! Single-cell resolution imaging of #mRNA-LNP biodistribution in cleared mouse bodies. www.nature.com/articles/s41...

Exciting news! @basemrna.bsky.social and Vaxxas have been awarded the $2M USD Biomedical Advanced Research and Development Authority (BARDA) Patch Forward Concept Stage Prize to develop thermostable needle-free mRNA vaccines. www.uq.edu.au/news/article...

#mRNA meets cell therapies! It was great to collaborate with Fernando Guimaraes's team to develop mRNA CARs and delivered them to NK cells. NKs transfected with EphA2 CAR mRNA elicited a strong anti-tumour response in animal sarcoma models. onlinelibrary.wiley.com/doi/10.1002/...

Out of office

Awesome work from Michael Mitchell's lab at UPenn in @natureportfolio.bsky.social identifies novel LNPs that can deliver #mRNA to the placenta. Using the placenta-targeting LNPs to deliver VEGF mRNA improves pre-eclampsia in animal models. www.nature.com/articles/s41...

Earlier this year I had the opportunity to present a TEDx talk on the transformative potential of personalised #mRNA vaccines for cancer. The recording is out now: www.youtube.com/watch?v=BnSO... #RNAsky #RNAtx @basemrna.bsky.social

How I imagine our lab animals talk to each other.

There are more ways to design an mRNA than atoms in the universe, so how do you choose the best one? Our new @basemrna.bsky.social software, mRNArchitect enables you to tune expression, stability, reactogenicity and synthesisability to design more potent #mRNA drugs. www.biorxiv.org/content/10.1...

mRNA-encoded transcription factor inhibitors are a rapidly emerging class of drugs. In Science Translational Medicine a team at Harvard treated retinal disease in animals by inhibiting RUNX1. Stay tuned for our forthcoming work targeting cancer transcription factors. www.science.org/doi/10.1126/...

I made a starter pack for interesting people in the mRNA vaccines and therapeutics space. Message me if you want to be added. #RNAsky go.bsky.app/VSHfBce

ARC says they’ll release the Discovery Projects 2025 outcomes tomorrow. Recently, outcomes announcements have tended to happen at/around 11am Canberra time. My bot will pick up the announcement in RMS’s database and post immediately. Good luck!

Cool paper on ribozyme-mediated trans-ligation of mRNAs to deliver larger cargo. I love this concept, but the examples seem a little engineered. We can and do make conventional mRNAs up to 10kb and greater without any problems. Interested in what others think. #RNAsky www.science.org/doi/10.1126/...

Noncoding RNA pioneer Howard Chang will be the new Chief Scientific Officer of Amgen. Interesting move. www.fiercebiotech.com/biotech/amge...
