Importantly there is a deficiency in basic science translation and clinical studies including women or female pre-clinical models #InclusionMatters. Everyone equally deserves breakthrough medications treatments and cures for illnesses. It all begins with NIH funded basic science to study diversity

Ultimately, we propose a coordinated transcriptional mechanism involving Xbp1 and Myc to alleviate UPR and stimulate beta cell proliferation in obese female mice

We unify independent observations of UPR (Laura Alonso
@JimJohnsonSci Jesper Gromada) and Myc (Vincent Poitout Adolfo Garcia Ocaña Donald Scott Andy Stewart) regulated beta cell proliferation, while identifying novel aspects of stress attenuation and Myc transcriptional co-regulators

High confidence transcriptional target (HCT) analysis (McKenna/Ochsner) lead us to identify the enrichment of specific Myc co-regulators (Hcfc1 and Wdr5) that may determine specific gene programs activated by Myc during UPR and Xbp-1 activation to drive beta cell proliferation

Acute Lepr KO induces an Xbp1 regulated transcriptional program to resolve UPR stress during adaptive beta cell proliferation. UPR resolution involved attenuation of HSF1 gene regulation and increased ribosomal biogenesis associated with prominent MYC transcriptional activity

Overall, we captured the transcriptional signatures of beta cell populations undergoing adaptive stress (without decompensation) and attenuation in association with significant beta cell proliferation (~20% of all beta cells) in obese female mice following acute leptin receptor KO

Obesity is the most potent physiologic stimulus to expand beta cells in both humans and pre-clinical models, representing a significant opportunity to identify relevant robust targets that translate to humans to expand and regenerate beta cells as replacement therapy in #T1D #T2D

This was fun project not possible without my amazing co-authors: Dr. Sean Hartig animal studies, writing, support, mentorship; Peter Masschelin talented grad student at the time performed single cell analyses; Drs. Neil McKenna and Scott Ochsner for innovative bioinformatics tool

Also shoutout to the amazing Dr. Kendra Carmon!
