    Abstract

    WFS1 Functions in ER Export of Vesicular Cargo Proteins in Pancreatic β-Cells

    Researchers showed that endoplasmic reticulum (ER) to Golgi transfer of vesicular cargo proteins required WFS1, an ER-associated membrane protein whose loss of function led to Wolfram syndrome.

    Drug-Dependent Morphological Transitions in Spherical and Worm-Like Polymeric Micelles Define Stability and Pharmacological Performance of Micellar Drugs

    It was observed that poly(2-oxazoline)-based polymeric micelles could be elongated over time from a spherical structure to worm-like structure, with elongation influenced by several conditions, including the amount and type of drug loaded into the micelles.

    CHK1 Protects Oncogenic KRAS-Expressing Cells from DNA Damage and Is a Target for Pancreatic Cancer Treatment

    Pharmacologic inhibition of CHK1 alone caused apoptotic growth suppression of both PDAC cell lines and organoids, which correlated with loss of MYC expression.

    Glutamine Deprivation Triggers NAGK-Dependent Hexosamine Salvage

    The authors identified that glutamine limitation in pancreatic ductal adenocarcinoma cells suppressed de novo hexosamine synthesis but resulted in increased free GlcNAc abundance.
