, and the groups of Rob Taylor, Nurten Akarsu, and Mark Craven.
@HHMINEWS
I’m honored and humbled to be joining this inspiring cohort of new HHMI Investigators, and extremely grateful for the talented scientists I’ve had the privilege of working with in my lab these past 15 years. This is really a reflection of their efforts and ingenuity!
@HHMINews
Happy to share our new mitochondrial proteome research review out today in

#Mitochondria
Excited to share our new discovery of a mitochondrial isoprene transporter published today in
@NatureCellBio
and led by
@mitojondrion
! Interesting example of transporter dual functionality.
#Mitochondria
After 10+ fantastic years in Madison, it is bittersweet to announce that my lab and I are moving to
@WUSTLmed
soon. I am so grateful to everyone at
@UWBiochem
and
@Morgridge_Inst
for their support and guidance. Stay healthy, and come visit us in St. Louis!
Equally excited to share our new
@nchembio
paper describing a mitochondria-specific repurposed kinase inhibitor to manipulate CoQ biosynthesis. Congrats to lead author
@nhmurray12
, Chris Asquith, and all our collaborators!
Many thanks for all the very kind messages! My team and I are excited by all the ways this will empower our science, hopefully in collaboration with many of you.
I’m pleased to share our new work on the mitochondrial phosphatase PPTC7 led by
@nieminm
! Check out the important roles this protein plays in mitophagy and metabolic regulation.
#mitochondria
CoQ10 is large and very hydrophobic, which limits its bioavailability. Our new study, led by
@LauraSteenberge
, shows that CoQ4 is a sufficient substitute for multiple CoQ functions in cells and can be targeted to mitochondria.

We are very excited to be up and running at

#Mitochondria
CoQ10 is a very hydrophobic molecule with poor bioavailability. In this new study, led by
@LauraSteenberge
, we build on prior work to show that the much more soluble CoQ4 is sufficient to rescue diverse CoQ functions and can be targeted to mitochondria.
I am happy to share (a bit late) our new review on coenzyme Q biology published recently in
@TrendsBiochem
. Congratulations to Dr. Rachel Guerra for leading the charge!
Coenzyme Q biochemistry and biosynthesis
Very excited to share our new
@MolecularCell
paper describing the structure and functionality of a CoQ-related complex. Wonderful collaboration with Adam Frost,

Quite honored to have
@SenatorBaldwin
visit our lab today! Senator Baldwin's grandfather, Dr. David E. Green, was a pioneer in mitochondrial biology. His lab's work at UW-Madison, especially on coenzyme Q, set the foundation for much of what we do today.
Very appreciative of this opportunity and thankful to my nominators and the amazing group of scientists I've had the privilege of working with. I certainly hope to emulate the incredible Stadtmans, both in their science and their mentorship!

A big congratulations to Kyle Robinson, who successfully defended his thesis today! That makes 12 new PhDs from our lab in as many years. Well done, Dr. Robinson!
Excited that our work, led by
@nieminm
, is out. This phosphatase is key for mitochondrial function and there is a lot left to learn. Those interested in knowing more should make Natalie your next faculty hire — she is fantastic and on the market!
COQ9 repurposed an ancient bacterial fold to help surmount the hydrophobic barriers of CoQ biosynthesis. Excited to have this work—led by two outstanding graduate students—now in print in

#tbt
today is David Ezra Green! Green worked out the reduction potentials of
#cysteine
#glutathione

#redox
potentials which had important implications for their role in biology. Paper!
I had my shoes shined (badly needed) at the Minneapolis airport today by a 94-year-old legend of a WWII vet named Paul. I asked him if he had any dietary secrets. “Nah, I eat EVERYTHING.” And also does karate and “teaches dancing.” Humbling.
#metabolism
Likewise thrilled to be teaming up with
@bradylabupenn
and the
@ASBMB
team to put together this program. So many great theme leaders and speakers already lined up. Join us in Chicago!
Have trainees who would like to learn mass spectrometry? Join us in Madison July 21-24 for our second annual North American Mass Spectrometry Summer School.

I echo this sentiment and congratulations. This was a special event. The whole experience (for me in 2016, last of the Obama administration) was very uplifting and left us with a sense of optimism about the future of science in our country. Congrats and enjoy!
Congrats to PECASE awardees!
It was a career highlight for me; my Dad flew in from India for this in 2010
If folks think this President has anything to do with PECASE selection or is likely to show up at ceremonies. they're deluded. So, don't be a killjoy!
I feel incredibly fortunate to have had the opportunity to train under
@Pagliarini_Lab
at
@uwmadisonipib

@JudithSimcox
as co-mentor along the way. Words cannot express how grateful I am for my amazing colleagues, friends, and family who always have my back. Thank you 🙏🏾
Multiple short presentation slots still open for early career scientists. The small meeting size (~150) offers a great chance to interact with prominent members of the field, and the breadth of topics helps us all expand our thinking.

CoQ is made in mitochondria, but gets transported to membranes throughout the cell through unknown means. This work implicates two poorly characterized mitochondrial inner membrane proteins in the process.
Did you miss the live broadcast of Session 1 of
@UMDF
Mitochondrial Medicine today? No worries! All meeting registrants have on-demand access to recordings of all conference presentations. Session 2 live on Friday, May 21st. to register.
We’d also like to thank
@NatureComms
and our anonymous reviewers, who provided three tough but very fair and insightful reviews that helped make the paper better. So nice when the peer review process works as it is intended!
How do you achieve site (mitochondria)-specific delivery of copper through elesclomol - a copper ionophore? Check out our recent paper that answers this question.
@KatsuFunai
@LauraSteenberge
Thanks, very glad to hear this! We purchased from Sigma in the past, but Santa Cruz Biotechnology and MedchemExpress also both sell CoQ4.
@PIHanson
This was a special honor! So great to be back on campus, meet former colleagues, and see all the ways the department and program have grown. Biological Chemistry is sure in good hands with
@PIHanson
at the helm!
I second that, Scot! Stay tuned for more to come from
@Zak_Bakes
. We'd like to keep him this side of the border, but he'd be a gem for any Canadian University.
Thanks for sharing Dave! And Canadian Unis look out for
@Zak_Bakes
who is a super talented PDF who will be looking for Faculty positions north of the border shortly.
