Patient-derived gastric cancer organoids serve as in vitro models that closely mimics donor characteristics, offering new opportunities for both basic and applied research.

Personalized Vascularized Tumor Organoid-on-a-Chip for Tumor Metastasis and Therapeutic Targeting Assessment.

While tumor organoids have revolutionized cancer research by recapitulating the cellular architecture and behaviors of real tumors in vitro, their lack of functional vasculature hinders their attainment of full physiological capabilities. Current efforts to vascularize organoids are struggling to achieve well-defined vascular networks, mimicking the intricate hierarchy observed in vivo, which restricts the physiological relevance particularly for studying tumor progression and response to therapies targeting the tumor vasculature. An innovative vascularized patient-derived tumor organoids (PDTOs)-on-a-chip with hierarchical, tumor-specific microvasculature is presented, providing a versatile platform to explore tumor-vascular dynamics and antivascular drug efficacy.

Modeling Fibrous Tissue in Vascular Fluid-Structure Interaction: A Morphology-Based Pipeline and Biomechanical Significance.

Modeling fibrous tissue for vascular fluid-structure interaction analysis poses significant challenges due to the lack of effective tools for preparing simulation data from medical images. This limitation hinders the physiologically realistic modeling of vasculature and its use in clinical settings. Leveraging an established lumen modeling strategy, we propose a comprehensive pipeline for generating thick-walled artery models.

Urolithin A attenuates Doxorubicin-induced cardiotoxicity by enhancing PINK1-regulated mitophagy via Ambra1.

Doxorubicin (Dox) is a widely used antineoplastics although its clinical usage is greatly limited by its cardiotoxicity. Several studies have depicted an essential role for dampened mitophagy and mitochondrial injury in Dox cardiotoxicity. However, preventative measure to alleviate Dox-evoked cardiotoxicity via targeting mitophagy and mitochondrial integrity remains elusive.

AYVM to AYMM transition on HER2 exon 20 insertion induces TKI resistance in NSCLC.

Pyrotinib, a novel pan-HER tyrosine kinase inhibitor, has demonstrated substantial anti-tumor activity in non-small cell lung cancer (NSCLC) patients harboring HER2 mutations. However, the inevitable resistance to pyrotinib necessitates an in-depth understanding of the underlying mechanisms. In this study, potential resistance-associated mutations were identified through genomic sequencing of clinically paired samples and were validated using in vitro and in vivo models.

Tumor metastasis and recurrence: The role of perioperative NETosis.

Although surgical resection of tumor mass remains the mainstay of curative therapeutic management for solid tumors, accumulating studies suggest that these procedures promote tumor recurrence and metastasis. Regarded as the first immune cells to fight against infectious or inflammatory insults from surgery, neutrophils along with their ability of neutrophil extracellular traps (NETs) production has attracted much attention. A growing body of evidence suggests that NETs promote cancer metastasis by stimulating various stages, including local invasion, colonization, and growth.

The polycomb protein complex interacts with GATA-6/PPARα to inhibit α-MHC expression.

Transcription factors collaborate with epigenetic regulatory factors to orchestrate cardiac differentiation for heart development, but the underlying mechanism is not fully understood. Here, we report that GATA-6 induces cardiac differentiation but peroxisome proliferator-activated receptor α (PPARα) reverses GATA-6-induced cardiac differentiation, possibly because GATA-6/PPARα recruits the polycomb protein complex containing EZH2/Ring1b/BMI1 to the promoter of the cardiac-specific α-myosin heavy chain (α-MHC) gene and suppresses α-MHC expression, which ultimately inhibits cardiac differentiation. Furthermore, Ring1b ubiquitylates PPARα and GATA-6.

Expert consensus on sequential surgery following conversion therapy based on combination of immune checkpoint inhibitors and antiangiogenic targeted drugs for advanced hepatocellular carcinoma (2024 edition).

Up to half of hepatocellular carcinoma (HCC) cases are diagnosed at an advanced stage, for which effective treatment options are lacking, resulting in a poor prognosis. Over the past few years, the combination of immune checkpoint inhibitors and anti-angiogenic targeted therapy has proven highly efficacious in treating advanced HCC, significantly extending patients' survival and providing a potential for sequential curative surgery. After sequential curative hepatectomy or liver transplantation following conversion therapy, patients can receive long-term survival benefits.

Corticosteroid dose escalation in non-ICU COVID-19 patients with worsening lung lesions reduces lesion severity without improving clinical outcomes.

The effect of increasing corticosteroid doses on clinical outcomes and chest findings in patients with coronavirus disease (COVID-19) pneumonia and lung disease remains unknown. We aimed to investigate the effects of increasing steroid dosage on chest lesion area and clinical outcomes in patients with moderate or severe COVID-19 and progressive lung involvement on chest computed tomography (CT). A total of 105 patients with radiological progression during methylprednisolone (MP) therapy either received an increased MP dose (n = 79) or were maintained on the same MP dose (n = 26).

Cardiac secreted HSP90α exacerbates pressure overload myocardial hypertrophy and heart failure.

Sustained myocardial hypertrophy or left ventricular hypertrophy (LVH) triggered by pressure overload is strongly linked to adverse cardiovascular outcomes. Here, we investigated the clinical relationship between serum HSP90α (an isoform of HSP90) levels and LVH in patients with hypertension or aortic stenosis (AS) and explored underlying mechanisms in pressure overload mouse model. We built a pressure overload mouse model via transverse aortic constriction (TAC).

Brazilin alleviates acute lung injury via inhibition of ferroptosis through the SIRT3/GPX4 pathway.

Ferroptosis is a novel type of programmed cell death dependent on iron and is characterized by the accumulation of lipid peroxides, which is involved in acute lung injury (ALI). Brazilin, an organic compound known for its potent antioxidant and anti-inflammatory properties, has not been thoroughly studied for its potential impact on lipopolysaccharide (LPS)-induced ALI. Here, we found that pretreatment of brazilin mitigated LPS-induced lung injury and inflammation by inhibiting mitochondrial oxidative stress and ferroptosis, both in vivo and in vitro.

LncRNA EGFR‑AS1 promotes lung cancer cell proliferation, invasion and metastasis via regulation of miR‑449a/HDAC1.

There is increasing evidence that long non-coding (lnc)RNA EGFR-AS1 is involved in the development of numerous types of cancer, including non-small-cell lung cancer (NSCLC). The Cancer Genome Atlas (TCGA) demonstrates that EGFR-AS1 is highly expressed in NSCLC. Downregulation of EGFR-AS1 in A549 and PC9 NSCLC cells demonstrates inhibition of NSCLC proliferation, invasion and metastasis.

Effect of Position-Based Dosing Strategy for Metaraminol on Neonatal Acid-Base Status During Elective Caesarean Delivery: A Noninferiority Randomised Controlled Trial.

Background: The 15° left tilt position during caesarean delivery has been recommended by guidelines for many years, but recent studies have questioned the clinical benefit of left tilt position.
