A new workhorse has arrived! Our lab installed a Waters Xevo G3 Q/ToF today. Looking forward to play with it for observing metabolites!!

Yesterday @roman-bushuiev.bsky.social visited our lab. He gave a seminar talk about his recent work on DreaMS (www.nature.com/articles/s41...), and provided a hands-on training to my lab members. Looking forward to what we will discover using this awesome tool!

Flying to Prague for #Metabolomics2024, the MetabolomeXchange meeting, and some other things. See you soon dear Metabolomics folks!

As Penicillium spp. are well-known producers of antibiotic compounds, we wondered if this effect can 'cross-protect' the other bacteria. We performed tripartite cultures of Penicillium-B. subtilis-(E. coli or Ps. putida), and saw that bacillibactin availability decides who will be dominant. 5/6

We wondered why, and we focused on a metabolite induced by coculture - bacillibactin, a siderophore of B. subtilis. We tested a B. subtilis 168 that cannot produce bacillibactin and saw that the inhibitory effect on specialized metabolism was weaker in cases with this strain. 3/6

This was an unexpected discovery from our project on 85 Penicillium spp.-B. subtilis cocultures. We expected coculture would boost Penicillium specialized metabolism. However, untargeted metabolomics told us the opposite. Most metabolites showed decreased amount in coculture. 2/6

Thanks to the KR-FR STARS grant, we could meet up with each other in Paris and Seoul in 2023, which brought us to the others of each one's local socities (KSP and AFERP). Congratulations everyone, especially Sarah, @mehdibeni.bsky.social and @adafede.bsky.social 🎉

We even put this table in our manuscript, which provides almost every available information on antibodies we used. Please never submit to this journal. I really doubt their expertise.

I submitted a manuscript to Pharmaceutical Biology, a @tandfresearch.bsky.social journal. They held it for a year with five-round minor revisions, then rejected it because we did not give UniProtID for epitopes of secondary antibodies, that is unknown to anyone. Are you kidding me??

My university opened a new facility equipped with two cutting edge Waters mass specs. SELECT SERIES cyclic IMS and MALDI/DESI multi-reflecting imaging MS! So looking forward to playing woth these machines.

After the SIMB NP meeting ended, I, my lab postdoc Eunjin, my colleague Chungsub, and two PhD students from SNU visited the Dorrestein lab and had a very nice scientific discussion. Thank you @pieterdorrestein.bsky.social and Ipsita! It was so fun to be back in the lab.

SIMB NP2025 starts with a keynote speach of Nobel Prize laureate Jennifer Doudna. A structure-based discovery of an ancestral CRISPR-Cas13 (doi.org/10.1126/scie...) and a viral proteome study (www.nature.com/articles/s41...) were discussed.

Last week our lab had a joint symposium with the plant-insect interaction & ecology lab led by Youngsung Joo, SNU (jooandlee-eco.weebly.com). Recently we won a grant together. Stay tuned for our collaboration on the ecological function of plant secondary metabolites, powered by metabolomics!
