Excited to share our latest story on the regulation of lysosomal BMP lipids! Co-led with Raghav Jain, we show that PLA2G15 is a BMP hydrolase that regulates lipid levels under the transcriptional control of TFEB. @JudithSimcox @UWBiochem @HHMINEWS
New! Online now: Hepatic lipid remodeling in cold exposure uncovers direct regulation of bis(monoacylglycero)phosphate lipids by phospholipase A2 group XV https://t.co/QcT4tpbNWl

Great work by Mugagga, @LainyVonBank and @_JessDavidson from the Simcox Lab! SCD1 is known to regulate the production of monounsaturated fatty acids and development of diabetes in response of high carbohydrate diet. We showed loss of SCD1 also controls acylcarnitine levels.
Research from the James Ntambi and @JudithSimcox Labs reveals an enzyme’s important role in maintaining a healthy balance of lipids in our bodies. More on their latest research:

As promised, a 🧵 on our recent article now out in @NatureSMB! Co-led with @AbbyBartlett_ @Pagliarini_Lab @JudithSimcox, we find ACAD10/11 are NOT like other acyl-CoA dehydrogenases and instead catabolize atypical lipids called 4-hydroxy acids 🤯#lipidtime

5/ There are still many unanswered questions on PLA2G15 post-translational regulation and stereoisomer specificity for BMPs to be explored in the future. But this is a huge step forward for the field and I’m thrilled to be a part of such impactful, collaborative research.

4/ This is exciting, as PLA2G15 was identified as a BMP lipid hydrolase not only by us but also in recent work from our collaborators in the @abu_remaileh lab who further characterized PLA2G15 as a potential therapeutic target in NPC disease.

3/ We identified PLA2G15 as a target of TFEB; TFEB directly binds and suppresses transcription of Pla2g15 during cold exposure. Through knockdown, knockout, and rescue models in cells and mice, we determined that PLA2G15 degrades BMP lipids.

2/ As part of the metabolic adaptation to cold exposure, lysosomal lipid processing is altered and BMP lipid levels are increased in the liver. We found that this response is transcriptionally controlled by TFEB. Knockdown of TFEB leads to cold intolerance in mice.

1/ Localized to the lysosome, BMP lipids are known to mediate lipid and protein degradation. While they are critical to lysosomal function, there are still many unanswered questions regarding BMP lipid regulation.

Stoked for the opportunity to share some of my translational research with the Biochemistry community at the University of Utah next week!
We will be welcoming nine talented Graduate Student Rising Stars to share their research with us on Monday May 19th, starting at 9:30am in HSEB 1730. The symposium will be followed by the Pace Keynote talk by Dr. Toto Olivera at 4pm!

“I love the flexibility of working in science”, she whispers to herself as she rolls into lab on a weekend morning for the umpteenth time to do cell culture and check a mass spec run.
