ARNT-dependent HIF-2α signaling protects cardiac microvascular barrier integrity and heart function post-myocardial infarction.

Myocardial infarction (MI) compromises the cardiac microvascular endothelial barrier, increasing leakage and inflammation. HIF2α, predominantly expressed in cardiac endothelial cells during ischemia, has an unclear role in barrier function during MI. Here, we show that inducible, adult endothelial-specific deletion of Hif2α in mice leads to increased mortality, cardiac leakage, inflammation, reduced heart function, and adverse remodeling after MI.

Performance of Raman Spectroscopy in biopsy tissue for rapid diagnosis of Tracheobronchial Tuberculosis: a prospective study.

Tracheobronchial tuberculosis (TBTB) is a specific form of pulmonary tuberculosis characterized by Mycobacterium tuberculosis involvement in the tracheobronchial tree. Rapid and accurate diagnostic tools for TBTB are crucial. Raman spectroscopy (RS) is a noninvasive tool that accesses molecular vibrations and sample characteristics, enabling the creation of a molecular fingerprint of biological samples, which has enormous potential on clinical diagnosis for TBTB.

Self-assembled metal-coordinated nanoparticles for synergistic energy metabolism inhibition and low-temperature photothermal therapy.

Photothermal therapy has been observed to upregulate the heat shock protein 70 (HSP 70) expression in tumor cells, consequently diminishing the anti-tumor efficacy of the treatment. The expression of HSP 70 is intricately linked to the adenosine triphosphate (ATP) levels within tumors, suggesting that modulating energy metabolism could potentially enhance the effectiveness of photothermal therapy. To address these challenges, ATO-QUE-Fe-PVP K30 nanoparticles (AQFP NPs) were synthesized through the coordinated self-assembly of the oxidative phosphorylation (OXPHOS) inhibitor atovaquone (ATO) and the glycolysis inhibitor quercetin (QUE) with ferrous ions (Fe) for synergetic energy depletion and low-temperature photothermal therapy (LTPTT).

Novel repetitive elements in plant-specific tails of Gγ proteins as the functional unit in G-protein signalling in crops.

Heterotrimeric G proteins act as molecular switches in signal transduction in response to stimuli in all eukaryotes. However, what specifies G protein signalling in plants and how the mechanism evolved and diverged remain unsolved. Here, we found that the recently evolved tails of three Gγ subunits, Dense and erect panicle 1 (DEP1), G protein gamma subunit 2 of type C (GGC2), and Grain size 3 (GS3), determine their distinct functions and specify grain size in rice (Oryza sativa L.

Transcription factor VIB-1 activates catalase-3 expression by promoting PIC assembly in Neurospora crassa.

The "p53-like" superfamily transcription factor, VIB-1, plays a crucial role in mediating heterokaryon incompatibility and regulating the transcription of specific genes involved in the secretion of extracellular hydrolases in Neurospora crassa. However, the precise mechanism underlying the transcriptional regulatory function of VIB-1 is still poorly understood. Here, we reveal that VIB-1 is involved in the H2O2-induced oxidative stress response, in which deletion of vib-1 leads to an H2O2-sensitive phenotype and inhibition of cat-3 expression.

A single-dose, four-cycle, fully repetitive crossover bioequivalence of dabigatran etexilate in Chinese.

Purpose: Among healthy Chinese subjects, two capsules of dabigatran etexilate were tested for bioequivalence.

Method: Fifty healthy subjects were recruited for each of the fasting and postprandial trials in a randomized, two-sequence, open-label, four-cycle, fully replicated trial design of a single 150 mg dose of either the test or the reference formulation of dabigatran etexilate capsules in the fasting and postprandial states. The blood concentration of dabigatran at different time points after administration was determined by high-performance liquid chromatography-tandem mass spectrometry (HPLC-MS/MS).

Dual-channel compression mapping network with fused attention mechanism for medical image segmentation.

Accurate image segmentation is the key to quantitative analysis and recognition of pathological tissues in medical imaging technology, which can provide important technical support for medical diagnosis and treatment. However, the task of lesion segmentation is particularly challenging due to the difficulty in identifying edges, the complexity of different tissues, and the variability in their shapes. To address these challenges, we propose a dual-channel compression mapping network (DCM-Net) with fused attention mechanism for medical image segmentation.

Experimental study on the mechanism of rockburst in tunnel construction by drilling and blasting construction in high ground stress stratum.

In order to explore the mechanism of rockburst in tunnels constructed by drilling and blasting method in high ground stress strata, this study reformed the physical model test system of rockburst in deep tunnels and the high-pressure gas explosion excavation system, and successfully reproduced the process of rockburst disaster in drilling and blasting construction. Based on the existing research results and preliminary tests, a composite material with similar brittleness and rock burst tendency index to the granite on site was developed, and a cubic rock burst model of 500 × 500 × 500 mm was poured. The test results show that in the gas explosion excavation, the air pressure impact causes the test block to be destroyed instantaneously, the small fragments splash and the explosion sound is significant, indicating that the instantaneous release of gas can cause material damage and simulate the dynamic characteristics of the blasting process.

Deep learning prioritizes cancer mutations that alter protein nucleocytoplasmic shuttling to drive tumorigenesis.

Genetic variants can affect protein function by driving aberrant subcellular localization. However, comprehensive analysis of how mutations promote tumor progression by influencing nuclear localization is currently lacking. Here, we systematically characterize potential shuttling-attacking mutations (SAMs) across cancers through developing the deep learning model pSAM for the ab initio decoding of the sequence determinants of nucleocytoplasmic shuttling.

Telomere length in offspring is determined by mitochondrial-nuclear communication at fertilization.

The initial setting of telomere length during early life in each individual has a major influence on lifetime risk of aging-associated diseases; however there is limited knowledge of biological signals that regulate inheritance of telomere length, and whether it is modifiable is not known. We now show that when mitochondrial activity is disrupted in mouse zygotes, via exposure to 20% O or rotenone, telomere elongation between the 8-cell and blastocyst stage is impaired, with shorter telomeres apparent in the pluripotent Inner Cell Mass (ICM) and persisting after organogenesis. Identical defects of elevated mtROS in zygotes followed by impaired telomere elongation, occurred with maternal obesity or advanced age.

Biological roles and clinical applications of EpCAM in HCC.

Epithelial cell adhesion molecule (EpCAM) is an important biomarker in tumors. In hepatocellular carcinoma (HCC), EpCAM + cells exhibit high invasiveness, tumorigenic ability, therapeutic resistance, and self-renewal ability, often identified as liver cancer stem cells (CSCs). Detecting EpCAM + cells in tumor lesions and circulation is valuable for predicting patient prognosis and monitoring therapeutic outcomes, emphasizing its clinical significance.

STAT1 increases the sensitivity of lung adenocarcinoma to carbon ion irradiation via HO-1-mediated ferroptosis.

Radiotherapy is a vital treatment agent for lung adenocarcinoma (LUAD) patients, while radioresistance remains a major factor in treatment failure. Here, we aimed to elucidate how signal transducer and activator of transcription 1 (STAT1) affected sensitivity to carbon ion irradiation for LUAD cells in vivo and in vitro. The results of colony formation, CCK-8, EdU, and calcein-AM/PI double-staining assays demonstrated that the overexpression of STAT1 markedly enhanced the inhibitory effect of carbon ion irradiation on the viability of LUAD cells (A549 and PC9 cells).
