Advanced Science, EarlyView.The hyperactivation of PI3K/AKT signaling in PTEN wild‐type triple‐negative breast cancer represents a clinical paradox. We delineate a novel post‐translational regulatory axis wherein the oncogene TSPYL5 competitively antagonizes the deubiquitinase USP10.

Hepatology, EarlyView., 2022 A deleterious variant of FCHSD1 results in mTOR pathway overactivation and may cause porto‐sinusoidal vascular disorder (PSVD). The pedigree of the family demonstrated an autosomal dominant disease with variable expressivity. Whole‐genome sequencing and Sanger sequencing both validated the existence of the FCHSD1 variant and the heterozygosity of c ...

Advanced Science, EarlyView.This study demonstrates that iron overload triggers widespread chromatin compaction and transcriptional repression in human granulosa cells, recapitulating features of endometriosis. The epigenetic reprogramming is orchestrated by a TFEB‐SOX4‐SWI/SNF axis, with SOX4 acting as a central, dosage‐sensitive regulator.

Interleukin‐18 signaling promotes activation of hepatic stellate cells in mouse liver fibrosis
Hepatology, EarlyView., 2022 Interleukin‐18 signaling promotes activation of hepatic stellate cells in mouse liver fibrosis. Abstract Background and Aims Nucleotide‐binding oligomerization domain‐like receptor‐family pyrin domain‐containing 3 (NLRP3) inflammasome activation has been shown to result in liver fibrosis.

Effects of 5-hydroxytryptamine on spermatozoal hyperactivation and in vitro fertilization in mice
The Journal of Reproduction and Development, 2019 In this study, we examined the effects of 5-hydroxytryptamine (5-HT) on the motility and hyperactivation of mouse spermatozoa. In addition, we examined whether 5-HT increases the success of in vitro fertilization (IVF) in mice.

, 1998 OBJECTIVE: To evaluate the influence of human granulosa cell (GC) cultures and follicular fluid (FF) on sperm kinetic parameters, hyperactivation, and the acrosome reaction compared with the influence of human tubal fluid (HTF) and Ham's F-10 medium ...

UCHL3 Regulates Subgenomic Flaviviral RNA Condensates to Promote Virus Propagation
Advanced Science, EarlyView.ABSTRACT Flavivirus subgenomic RNAs (sfRNAs) antagonise antiviral defences, yet how sfRNAs are organized and maintained in cells remains poorly understood. Here we identify ubiquitin C‐terminal hydrolase L3 (UCHL3) as a post‐translational regulator of flavivirus sfRNA stability and function.

Neutrophil hyperactivation correlates with Alzheimer's disease progression
Annals of Neurology, 2018 ObjectiveRecent studies have underlined the effect of systemic inflammation on the pathophysiology of Alzheimer's disease (AD). Neutrophils are key components of early innate immunity and contribute to uncontrolled systemic inflammation if not tightly regulated.

Advanced Science, EarlyView.This study identifies S100A14 in tumor‐derived exosomes as a key driver of brain metastasis. S100A14 targets PIAS3 in astrocytes, activating STAT3 signaling and promoting immunosuppressive MDSCs recruitment via chemokine secretion. Germacrone, a natural compound, binds S100A14 to disrupt this axis, effectively inhibiting brain metastasis with low ...
