Transferrin Reduces the Production of Soluble Transferrin Receptor

Experimental Biology and Medicine, 1995
The effect of homologous diferric transferrin from which contaminating transferrin receptor has been removed by monoclonal antibody affinity chromatography on soluble transferrin receptor concentrations was studied in K562 cells and HL60 cells in culture.

Materials‐Guided Gene‐Ionizable Lipid Nanoparticles to Reverse Iron‐Associated Immune Resistance in Renal Cancer

Advanced Science, EarlyView.
ABSTRACT Iron overload is a common metabolic disturbance in cancer and contributes to poor outcomes in renal cell carcinoma (RCC), yet its effects on the tumour immune microenvironment remain unclear. Here we identify a previously unrecognized immunosuppressive axis in which iron overload downregulates the palmitoyltransferase ZDHHC12 in CD8+ T cells ...

MiR‐940 Suppresses Ferroptosis by Controlling Expression of Key Regulatory Genes

Advanced Science, EarlyView.
A CRISPR‐based screening identified miR‐940 as a critical suppressor of ferroptosis in cancer. By coordinating the downregulation of pro‐ferroptotic genes with the upregulation of GPX4, miR‐940 establishes a regulatory network that protects against ferroptosis and correlates with poor clinical outcomes in distinct cancer entities.

CAMKK2-CAMK4 signaling regulates transferrin trafficking, turnover, and iron homeostasis

Cell Communication and Signaling, 2020
Background Circulatory iron is a hazardous biometal. Therefore, iron is transported in a redox-safe state by a serum glycoprotein - transferrin (TF). Different organs acquire iron from the systemic circulation through a tightly regulated mechanism at the

Synergistic Remodeling of Tumor Immune Microenvironment via a DNA Nanodevice Integrating STING Activation and Lysosome‐Targeted PD‐L1 Degradation

Advanced Science, EarlyView.
A rational design DNA nanoplatform not only achieves efficient PD‐L1 degradation but also triggers robust STING signaling. The nanodevice effectively reprograms “cold” tumors, leading to potent inhibition of tumor growth and metastasis in vivo. ABSTRACT The cGAS‐STING pathway is a cornerstone of innate antitumor immunity; however, its therapeutic ...

p300 Degradation by the p53‐SIAH1 Axis Relieves TBK1 Acetylation to Enhance Innate Antiviral Immunity

Advanced Science, EarlyView.
This study identifies p300 as the acetyltransferase that acetylates TBK1 and inhibits its phosphorylation. Activation of the p53‐SIAH1 axis by immune response downregulates p300 expression to sustain innate antiviral immunity. Conditional p300 knockout in alveolar epithelial cells in vivo promotes antiviral responses and suppresses virus replication ...

Inhibition of KDEL Receptors Remodels the Tumor Microenvironment for T Cell Independent Tumor Regression

Advanced Science, EarlyView.
Inhibition of KDELR2 in a small fraction of tumor cells generates sustainable immunogenic cell death conditions within the tumor microenvironment. These conditions promote the regression of tumors in a T cell independent manner. During regression, macrophages prime T cells that subsequently provide systemic protection against recurrence. The potency of

Serum hepcidin as a diagnostic test of iron deficiency in premenopausal female blood donors

Haematologica, 2011
Background Currently used indicators of iron status have limitations. Hepcidin, a key regulator of iron metabolism, is reduced in iron deficiency. We sought to determine the properties of hepcidin as a diagnostic test of iron deficiency.Design and ...

Human Urine Stem Cells Alleviate Pulmonary Fibrosis via Inhibiting Macrophage‐Myofibroblast Transition

Advanced Science, EarlyView.
Therapeutic role and mechanism of human urine stem cells (hUSCs) in pulmonary fibrosis. hUSCs alleviated pulmonary fibrosis by selectively inhibiting macrophage‐myofibroblast transition (MMT) in two ways: on one hand, hUSCs inhibited mitochondrial reactive oxygen species (mtROS) production and apoptosis/senescence of epithelial cells in pulmonary ...

Transferrin Receptor Mediated Brain Uptake During Ischemia and Reperfusion

Journal of Pharmacy & Pharmaceutical Sciences, 2013
Purpose. Drug delivery by transferrin receptor-mediated transport at the blood-brain barrier has shown beneficial effects in animal models of stroke, but it is unclear whether receptor mediated uptake remains functional in the ischemic tissue.
