Redox Cascade in Chicken Skeletal Muscle: SELENOT Suppression in Selenium Deficiency Triggers Disulfidptosis via mtROS‐NADPH Dysregulation

Advanced Science, EarlyView.
Se deficiency downregulates SELENOT, disrupting mitochondrial function and elevating mtROS to induce glucose metabolic reprogramming, NADPH depletion, cysteine accumulation, and disulfidptosis‐mediated actin cytoskeleton collapse in chicken skeletal muscle.

The serotonin transporter promotes a pathological estrogen metabolic pathway in pulmonary hypertension via cytochrome P450 1B1 pulmonary circulation [PDF]

, 2016
Pulmonary arterial hypertension (PAH) is a devastating vasculopathy that predominates in women and has been associated with dysregulated estrogen and serotonin signaling. Overexpression of the serotonin transporter (SERT+) in mice results in an estrogen-

PM2.5 Induce Endothelial‐Mesenchymal Transition and Cardiac Fibrosis via the NCOA4‐Mediated Ferritinophagy

Advanced Science, EarlyView.
This study primarily reveals that PM2.5‐derived Fe‐containing particles, particularly magnetite, are specifically enriched in the heart. Here, they interact with NCOA4 in endothelial cells, disrupt iron homeostasis by enhancing ferritinophagy, and subsequently trigger the process of EndMT through the NCOA4/KLF5 pathway.

Safety, tolerability, and efficacy of an in‐class combination therapy switch from bosentan plus sildenafil to ambrisentan plus tadalafil in children with pulmonary arterial hypertension

Pulmonary Circulation
The aim of this single‐centre retrospective observational study was to evaluate the safety, tolerability, and efficacy of an in‐class combination therapy switch from bosentan plus sildenafil to ambrisentan plus tadalafil in children with pulmonary ...

Right ventricular outflow tract velocity time integral-to-pulmonary artery systolic pressure ratio: a non-invasive metric of pulmonary arterial compliance differs across the spectrum of pulmonary hypertension. [PDF]

, 2019
Pulmonary arterial compliance (PAC), invasively assessed by the ratio of stroke volume to pulmonary arterial (PA) pulse pressure, is a sensitive marker of right ventricular (RV)-PA coupling that differs across the spectrum of pulmonary hypertension (PH ...

Single‐Cell Dissection of the Biological Function and Molecular Features Underlying the Micropeptide LSMEM1 in Kidney

Advanced Science, EarlyView.
LSMEM1, an evolutionarily conserved micropeptide with extreme hydrophobicity (aliphatic index═113) and dynamic amphiphilicity (GRAVY═0.017), features a strong α‐helical transmembrane anchor (residues 64‐86). Single‐cell analysis reveals its critical role in renal lipid homeostasis.

Sex-dependent influence of endogenous estrogen in pulmonary hypertension [PDF]

, 2014
Rationale: The incidence of pulmonary arterial hypertension (PAH) is greater in women suggesting estrogens may play a role in the disease pathogenesis. Experimentally, in males exogenously administered estrogen can protect against PH; however in models ...

Metabolic Interplay in Acute Lung Injury: PARK7 Integrates FADS1/2‐Dependent PUFA Metabolism and H3K14 Lactylation to Attenuate Endothelial Ferroptosis and Dysfunction

Advanced Science, EarlyView.
SCAP/ARDS patients show reduced unsaturated fatty acids (UFAs) but higher PARK7 and lactate in plasma. PARK7 correlates positively with lactate and negatively with UFAs. Pulmonary endothelial cell multi‐omics show FADS1/2 downregulation and impaired PUFA metabolism. Lactate boosts PARK7 via H3K14 lactylation, and PARK7 then restores FADS1/2.

DDAH1 regulates apoptosis and angiogenesis in human fetal pulmonary microvascular endothelial cells

Physiological Reports, 2019
Nitric Oxide (NO) is an endogenous pulmonary vasodilator produced by endothelial NO synthase (eNOS). Asymmetric dimethyl L‐arginine (ADMA) is an endogenous inhibitor of eNOS activity.

Single Mitochondrion Morphology‐Function Relationship Analysis Using Fluorescent Probes and Artificial Intelligence

Advanced Science, EarlyView.
An integrated strategy combining a mitochondria‐targeted fluorescent probe set and an AI framework enables simultaneous analysis of mitochondrial morphology and function at the single organelle level. By fusing multi‐parametric features, machine learning classification accurately distinguishes individual mitochondria under hypoxia‐related conditions ...
