Iron‐dependent lysosomal LDL oxidation induces the expression of scavenger receptor A in human THP‐1 monocytes

FEBS Open Bio, EarlyView.
In human monocytic cells THP‐1, a limited uptake of native—not oxidized—LDL/VLDL induced expression of scavenger receptor A and cellular adhesion. Induction was inhibited by lysosomotropic (WR‐1065) and lipophilic (BHT) antioxidants and by siRNAs against ferritinophagy.

GDP‐fucose transporter SLC35C1: a potential regulatory role in cytosolic GDP‐fucose and fucosylated glycan synthesis

FEBS Open Bio, EarlyView.
The inactivation of SLC35C1 (GDP‐fucose transporter) and enzymes involved in GDP‐fucose biosynthesis was studied. Fucose supplementation increases the level of GDP‐fucose to abnormal, millimolar values in the absence of the TSTA3 protein and SLC35C1 in contrast to the GMDS/SLC35C1 double mutant.

Determination of variability due to biological and technical variation in urinary extracellular vesicles as a crucial step in biomarker discovery studies

Journal of Extracellular Vesicles, 2019
Urinary extracellular vesicles (EVs) are an attractive source of biomarkers for urological diseases. A crucial step in biomarker discovery studies is the determination of the variation parameters to perform a sample size calculation.

Herbal Formula Yi‐Fei‐Jie‐Du‐Tang Regulates Epithelial‐Mesenchymal Transition and Vasculogenic Mimicry in Lung Cancer via HIF1A‐Mediated Ferroptosis

Advanced Biology, Volume 9, Issue 3, March 2025.
Yi‐Fei‐Jie‐Du‐Tang (YFJDT), a traditional Chinese medicine, has shown potential in lung cancer treatment by targeting key pathways. This study explores the mechanisms of YFJDT using bioinformatics, xenograft models, and A549 cells, demonstrating that YFJDT downregulates HIF1A, promotes ferroptosis, and inhibits epithelial‐mesenchymal transition (EMT ...
