    Baricitinib and β Cell Function in Patients with New-Onset Type 1 Diabetes

    In this Phase II, double-blind, randomized, placebo-controlled trial, scientists assigned patients with type 1 diabetes diagnosed during the previous 100 days to receive baricitinib or matched placebo orally for 48 weeks.

    Inflammation-Induced Subcutaneous Neovascularization for the Long-Term Survival of Encapsulated Islets without Immunosuppression

    Researchers showed that the induction of neovascularization via temporary controlled inflammation through the implantation of a nylon catheter could be used to create a subcutaneous cavity that supported the transplantation and optimal function of a geometrically matching islet-encapsulation device.

    BHLHE40 Inhibits Ferroptosis in Pancreatic Cancer Cells via Upregulating SREBF1

    Researchers highlighted the important roles of basic helix-loop-helix transcription factor 40 (BHLHE40)-mediated lipid peroxidation in inducing ferroptosis in pancreatic cancer (PCa) cells and provided a novel mechanism underlying sterol regulatory element-binding factor 1 (SREBF1) overexpression in PCa.

    Abstract

    SMAD4 Endows TGF-β1-Induced Highly Invasive Tumor Cells with Ferroptosis Vulnerability in Pancreatic Cancer

    The authors showed that SMAD4 status almost determined the orientation of transforming growth factor β1 (TGF-β1)-induced epithelial-mesenchymal transition via the SMAD4-dependent canonical pathway in PDAC, which altered ferroptosis vulnerability.
