I'm so relieved to finally get this one up as a preprint. We started this project back in 2019 when we created our first gemcitabine (GEMC) resistant (GEMR) #PDAC cell line. We showed that GEMR upregulates lipid synthesis and that targeting different steps could sensitise cells to GEMC. 1/n πŸ§ͺπŸ‘©β€πŸ”¬

Introducing Photochemical Action Plots as a Tool for Unlocking On‐Off Switchable Behavior in a Polymeric Eosin Y Photocatalyst Photochemical action plots are a powerful tool for investigating the wavelength-dependent efficiency of photochemical processes. Herein, we apply the photochemical action plot methodology developed b...

From photopolymerization (pubs.acs.org/doi/abs/10.1...) to ligation (pubs.acs.org/doi/abs/10.1...), wavelength-dependent quantum yields (www.nature.com/articles/s41...) and now photocatalysis: onlinelibrary.wiley.com/doi/10.1002/... - actions plots bring precision to photochemistry.

Ozone-enabled fatty acid discovery reveals unexpected diversity in the human lipidome - Nature Communications Fatty acids are fundamental biomolecular building blocks that are characterized by extraordinary structural diversity and present a formidable analytical challenge. Here the authors introduce a discov...

Ο‰-7 & Ο‰-10 PUFA: While both can be detected in neonatal skin lipids and some cancer cells (www.nature.com/articles/s41...), the Ο‰-7 PUFA, but no Ο‰-10 PUFA are found in liver tissue of obese mice on a high sugar & fat diet with MASH liver disease (pubs.acs.org/doi/abs/10.1...). What is FADS2 up to?

Skylite: Skyline-Based Lipid Isomer Retention Time Evaluation for Lipidomics in Metabolic Dysfunction-Associated Steatohepatitis Metabolic dysfunction-associated steatotic liver disease (MASLD) is the most prevalent liver disorder worldwide and can progress to steatohepatitis. Elevated de novo lipogenesis (DNL) is a key contrib...

We detected omega-7 polyunsaturated fatty acids (Ο‰-7 PUFA) in the livers of obese mice with liver disease (MASH, MC4R-KO), now published:

pubs.acs.org/doi/10.1021/...

Ο‰-9 PUFA in membrane lipids are also elevated - potential future biomarkers?

The Skylite workflow is based on LC-MS/MS.
