    Genetic Risk Converges on Regulatory Networks Mediating Early Type 2 Diabetes

    To identify early disease-driving events, researchers performed traditional and multiplexed pancreatic tissue imaging, sorted-islet cell transcriptomics and islet functional analysis of early-stage T2D and control donors.

    Urolithin C Alleviates Pancreatic β-Cell Dysfunction in Type 1 Diabetes by Activating Nrf2 Signaling

    Non-obese diabetic mice were administrated with urolithin C (UC) to evaluate UC-mediated protection of type 1 diabetes. The inflammation of the pancreas islets was examined by hematoxylin and eosin staining.

    Analysis of BRCA1- and BRCA2-Related Pancreatic Cancer and Survival

    This study included 234 consecutively identified patients with germline BRCA PVs and a diagnosis of PDAC. Of patients with BRCA1, 33 of 69 were males with a median age of 63 years. Of patients with BRCA2, 84 of 165 were males, and the median age was 64 years.

    Grad Students With Type 1 Diabetes Aim To Build a Better Future As Researchers, Advocates and Mentors

    PhD student Jasmine Maghera, who was diagnosed with T1D when she was 11, remembers being told that five years from her diagnosis she wouldn’t need to take insulin anymore: technology would make injecting insulin obsolete. Now Maghera’s goal is to create and share that technology.
