Single‐Cell Transcriptomics Unravels Growth Factor Erv1‐Like Mediated Ferroptosis as a Key Driver of Intestinal Epithelial Dysfunction in Ulcerative Colitis

Advanced Science, EarlyView.
Single‐cell transcriptomic profiling of ulcerative colitis (UC) tissues identified downregulation of GFER in intestinal epithelial cells. Mechanistically, GFER interacts with PCBP1 to help maintain intracellular iron homeostasis and may also reduce lipid peroxidation by activating the PGC‐1α/PPARγ signaling pathway, thereby inhibiting ferroptosis ...

Ribosome surface properties may impose limits on the nature of the cytoplasmic proteome

eLife, 2017
Much of the molecular motion in the cytoplasm is diffusive, which possibly limits the tempo of processes. We studied the dependence of protein mobility on protein surface properties and ionic strength.

Counterbalancing O‐GlcNAcylation and STAT3 Phosphorylation in Ventral Tegmental Area Dopaminergic Neurons Mediates Behavioral Adaptations to Acute Restraint Stress

Advanced Science, EarlyView.
Acute restraint stress enhances STAT3Ser727 phosphorylation in dopaminergic neurons in mice. This modification promotes the upregulation of GABBR2 and GABRB3, reduces neuronal activity, and contributes to anxiety‐like behavior and diminished reward‐seeking following stress exposure.

Trichothecene Mycotoxins Inhibit Mitochondrial Translation—Implication for the Mechanism of Toxicity

Toxins, 2011
Fusarium head blight (FHB) reduces crop yield and results in contamination of grains with trichothecene mycotoxins. We previously showed that mitochondria play a critical role in the toxicity of a type B trichothecene.

Deciphering the Role and Mechanism of Decidual Monocyte‐Derived Macrophage Infiltration in Obstetric Antiphospholipid Syndrome at Single‐Cell Resolution

Advanced Science, EarlyView.
This study uncovers a novel mechanism and therapeutic targets in obstetric antiphospholipid syndrome (OAPS). Antiphospholipid antibody/ß2‐glycoprotein I complex boosts CCL2 and TNF‐α expression in decidual macrophages via TLR4‐NF‐κB. CCL2 accumulates on endothelial surfaces via ACKR1, recruiting monocyte‐derived CCR2+ macrophages, driving inflammation,

OM14 is a mitochondrial receptor for cytosolic ribosomes that supports co-translational import into mitochondria

Nature Communications, 2014
It is well established that import of proteins into mitochondria can occur after their complete synthesis by cytosolic ribosomes. Recently, an additional model was revived, proposing that some proteins are imported co-translationally.

Anticodon Engineered Transfer RNA (tRNASUAG) Inhibits Hepatitis B Virus Replication by Promoting the Degradation of Core Protein

Advanced Science, EarlyView.
This study employed tRNASUAG, an anticodon‐engineered tRNA (ACE‐tRNA), to introduce a phosphorylatable serine into the C‐terminal domain of HBc by reading through its stop codon, thereby potentially promoting the ubiquitin‐proteasome degradation of HBc, and subsequently inhibiting HBV replication. Through a tRNASUAG‐gHBV1‐tRNASUAG‐gHBV2‐tRNASUAG tandem

STK25 Loss Augments Anti‐PD‐1 Therapy Efficacy by Regulating PD‐L1 Stability in Colorectal Cancer

Advanced Science, EarlyView.
This study demonstrates that STK25 depletion facilitates CRC immune escape through the inhibition of PD‐L1 Ser283 phosphorylation‐mediated ubiquitination, and promotes tumor growth. Furthermore, these findings identify STK25 as a potential therapeutic target to trigger antitumor immunity and promote immunotherapy efficacy. Abstract Tumor immune evasion
