I am honored to be on the ballot for @ASNKidney Councilor at large. Truly thankful to all the support and encouragement!

Kidney casts contain high levels of PROM1, a marker linked to cell damage and dedifferentiation based upon new #ASNCJASN study. https://t.co/G3LaMD65Hh

@Carmendemigue12 @KidneyInCVD Thank you so much Carmen! So kind of you. Big kudos to all the team, but especially Azuma Nanamatsu who has been the driving force behind this work.

What proteins do kidney tubular casts contain? More than what you think but with notable absences. New in CJASN https://t.co/NgvPDvHlxh

Times have changed. Reviewing papers stopped being predominantly a duty and an academic privilege, to also becoming an integral part of a multi-billion dollar publishing industry. Compensate reviewers? Any other examples of industry sustained by free work?

This perspective in ⁦⁦@asnpublications⁩ CJASN discusses the importance of spatial biology in studying kidney disease and the translational implications to identify therapeutic targets and biomarkers. https://t.co/ZjINVRGkGM

Happy to contribute to this superb work!

[ASN Publications @asnpublications]

The lymphatic system has historically been understudied due to the difficulty of distinguishing it from the blood vasculature. This #ASNKidney360 paper's authors optimized an antibody-based method for imaging hard-to-visualize adult murine kidney lymphatics. Read more: https://t.co/llmDQbxNC1

Linking histology with Omics. Happy to contribute to this work that offers a really nice tool. ⁦@_hubmap⁩ https://t.co/NNdGg0Nu98

Kudos to all the team @IUKidney and all the collaborators and especially the participant heroes from @KPMProject who made this work possible

[IU School of Medicine @IUMedSchool]

Kidney diseases are a leading cause of death in the U.S. They affect 14% of adults, often without knowing it. IU researchers are mapping kidney cell types to improve diagnosis and open the door to more precise therapies.

@ivivek87 Thanks! Yes, there were intermediary states THY1+, PROM1+(and VCAM1+), but loss of THY1 and persistence of PROM1 seems to correlate with injury and maladaptive repair.

[Tarek M. Ashkar (El-Achkar) @AshkarLab]

Our latest in ⁦@ScienceAdvances⁩ from a large collaboration through ⁦@KPMProject⁩ . We characterize a population of PTs in human kidney that express the regenerative marker THY1. THY1+ PTs are lost in kidney disease https://t.co/7VRrhl8wp7

[ASCI @the_asci]

Kidney cells can protect themselves during injury, but the mechanisms were unclear.

ASCI member Tarek M. El-Achkar @AshkarLab & team @IUMedSchool now show that oxidative stress induces an isoform of uromodulin that re-routes to the mitochondria to enhance energy production.

Very nice excited to see this work published and also the super well done editorial by @Vishal_D_Patel
