Targeting pancreatic cancer glutamine dependency confers vulnerability to GPX4-dependent ferroptosis.

Pancreatic ductal adenocarcinoma (PDAC) relies heavily on glutamine (Gln) utilization to meet its metabolic and biosynthetic needs. How epigenetic regulators contribute to the metabolic flexibility and PDAC's response and adaptation to Gln scarcity in the tumor milieu remains largely unknown. Here, we elucidate that prolonged Gln restriction or treatment with the Gln antagonist, 6-diazo-5-oxo-L-norleucine (DON), leads to growth inhibition and ferroptosis program activation in PDAC.

BMP4-GPX4 can improve the ferroptosis phenotype of retinal ganglion cells and enhance their differentiation ability after retinal stem cell transplantation in glaucoma with high intraocular pressure.

Activation of bone morphogenetic protein (BMP) 4 signaling promotes the survival of retinal ganglion cell (RGC) after acute injury. In this study, we investigated the role of the BMP4 signaling pathway in regulating the degeneration of retinal ganglion cells (RGCs) in a mouse glaucoma model and its potential application in retinal stem cell. Our results demonstrate that BMP4-GPX4 not only reduces oxidative stress and iron accumulation but also promotes neuroprotective factors that support the survival of transplanted RSCs into the host retina.

Fatty acid oxidation-induced HIF-1α activation facilitates hepatic urate synthesis through upregulating NT5C2 and XDH.

Dyslipidemia affects approximately half of all people with gout, and prior Mendelian randomization analysis suggested a causal role for elevated triglycerides in hyperuricemia (HU), but the underlying mechanisms remain elusive. We hypothesize that dyslipidemia promotes hepatic urate biosynthesis in HU and gout and fatty acid (FA) oxidation (FAO) drives this process. Here we developed a targeted metabolomics to quantify major metabolites in purine metabolic pathway in the sera of a human cohort with HU, gout, and normaluricemic controls.

Enhancer-driven Shh signaling promotes glia-to-mesenchyme transition during bone repair.

Plp1-lineage Schwann cells (SCs) of peripheral nerve play a critical role in vascular remodeling and osteogenic differentiation during the early stage of bone healing, and the abnormal plasticity of SCs would jeopardize the bone regeneration. However, how Plp1-lineage cells respond to injury and initiate the vascularized osteogenesis remains incompletely understood. Here, by employing single-cell transcriptional profiling combined with lineage-specific tracing models, we uncover that Plp1-lineage cells undergoing injury-induced glia-to-MSCs transition contributed to osteogenesis and revascularization in the initial stage of bone injury.
