Targeting Methylglyoxal Metabolism to Enhance Ferroptosis Sensitivity in Tumor Therapy.

Ferroptosis, characterized by iron-dependent lipid peroxidation, is a form of oxidative cell death increasingly recognized for its role in cancer therapy. The susceptibility of cancer cells to ferroptosis varies, highlighting the need to elucidate its underlying metabolic mechanisms. This study identifies a novel pathway in which the E3 ubiquitin ligase, praja ring finger ubiquitin ligase 1 (PJA1), mediates the proteasomal degradation of glyoxalase I (GLO1) exclusively in ferroptosis-sensitive cancer cells.

Hexokinase HK2 regulates the MYH9-GSK3β/β-catenin axis to promote myocardial regeneration and repair after injury.

Myocardial infarction (MI) causes irreversible loss of cardiomyocytes and can lead to heart failure. Previous studies have shown that hexokinase 2 (HK2) is significantly upregulated during the proliferative stage of cardiac injury. However, its role and mechanism in myocardial regeneration have not been clarified.

"Enduring in Marginalization": Deciphering Chinese Care Workers' Health Narratives Through a Culture-Centered Approach.

In China, care workers, mostly women, are as a distinct group with unique characteristics. These women experience prolonged marginalization and societal exclusion, ultimately rendering them vulnerable to health risks. This study adopts a culture-centered approach (CCA) to explore the health narratives of Chinese female care workers, examining the dialectical relationship between Chinese cultural customs, structural health determinants, and everyday agency of care workers' health.

WTAP Accelerates Exhaustion of CD8 T Cells and Progression of Hepatocellular Carcinoma by Promoting m6A Modification and Translation of PD1 mRNA.

The N6-methyladenosine (m6A) methylase WTAP has been identified as a proto-oncogene in multiple cancers, including hepatocellular carcinoma (HCC). Interestingly, although WTAP expression does not differ between normal liver and HCC tissues or across different stages of HCC, patients with higher WTAP expression exhibit significantly shorter median survival times (MSTs). Here, we found that WTAP was upregulated in tumor-infiltrating CD8 T cells, which were more enriched in HCC patients compared to the controls.

Intrapleural dual blockade of IL-6 and PD-L1 reprograms CAF dynamics and the tumor microenvironment in lung cancer-associated malignant pleural effusion.

With the increase in coal mining depths, soft and fractured roadway surrounding rocks require grouting and a sprayed protective layer for maintenance. Simultaneously, extensive accumulation of coal gangue causes diverse environmental issues. To enhance on-site coal gangue utilization, this study replaced river sand and cement with coal gangue to develop a novel cement-based mortar for supporting coal mine roadways.

The potential lipid biomarker 5-HETE for acute exacerbation identified by metabolomics in patients with idiopathic pulmonary fibrosis.

Background And Objective: Acute exacerbation (AE) is often the fatal complication of idiopathic pulmonary fibrosis (IPF). Emerging evidence indicates that metabolic reprogramming and dysregulation of lipid metabolism are distinctive characteristics of IPF. However, the lipid metabolic mechanisms that underlie the pathophysiology of AE-IPF remain elusive.

Knocking out USP7 attenuates cardiac fibrosis and endothelial-to-mesenchymal transition by destabilizing SMAD3 in mice with heart failure with preserved ejection fraction.

: Heart failure with preserved ejection fraction (HFpEF) is a predominant type of heart failure. Exploring new pathogenesis and identifying potential novel therapeutic targets for HFpEF is of paramount importance. : HFpEF mouse model was established by the "Multiple-hit" strategy, in that 18- to 22-month-old female C57B6/J mice fed with a high-fat diet were further challenged with chronic infusion of Angiotensin II.

A novel oral TLR7 agonist orchestrates immune response and synergizes with PD-L1 blockade via type I IFN pathway in lung cancer.

Despite the groundbreaking impact of immune checkpoint blockade (ICB), response rates in non-small cell lung cancer remain modest, particularly in immune-excluded or immune-desert microenvironments. Toll-like receptor 7 (TLR7) emerges as a latent target bridging innate and adaptive immunity, offering a promising avenue for combination therapies to augment ICB efficacy. Here, we explored the anti-tumor activity of the novel oral TLR7 agonist TQ-A3334 and its potential to enhance anti-programmed death ligand 1 (PD-L1) therapy through a combination strategy in a syngeneic murine lung cancer model.

NAT10-mediated upregulation of GAS5 facilitates immune cell infiltration in non-small cell lung cancer via the MYBBP1A-p53/IRF1/type I interferon signaling axis.

Interactions of tumor cells with immune cells in the tumor microenvironment play an important role during malignancy progression. We previously identified that GAS5 inhibited tumor development by suppressing proliferation of tumor cells in non-small cell lung cancer (NSCLC). Herein, we discovered a tumor-suppressing role for tumor cell-derived GAS5 in regulating tumor microenvironment.

The fate of antibiotic resistance genes in wastewater containing microalgae treated by chlorination, ultra-violet, and Fenton reaction.

Antibiotic resistance genes (ARGs) and bacteria (ARBs) in the effluent of wastewater treatment plants (WWTPs) are of utmost importance for the dissemination of ARGs in natural aquatic environments. Therefore, there is an urgent need for effective technologies to eliminate WWTP ARGs/ARBs and mitigate the associated risks posed by the discharged ARG in aquatic environments. To test the effective technology for eliminating ARGs/ARBs, we compared the removal of ARGs and ARBs by three different tertiary treatments, namely ultra-violet (UV) disinfection, chlorination disinfection, and Fenton oxidation.

Ablation for atrial fibrillation improves the outcomes in patients with heart failure with preserved ejection fraction.

The factors controlling antibiotic resistance genes in different treatment processes of mainstream full-scale wastewater treatment plants.

The alteration of antibiotic resistance genes (ARGs) in wastewater has been less studied in wastewater treatment plants (WWTPs), making it difficult to assess ARGs' spreading risk comprehensively. Therefore, this study investigated the distribution and reduction of ARGs in the main process (Anaerobic-Anoxic-Oxic with Membrane Bio-Reactor (A/O + MBR), Oxidation Ditch with sedimentation (OD), and Cyclic Activated Sludge System (CASS) with sedimentation) and disinfection process (Ultra-violet and Chlorination) of full-scale WWTPs. The wastewater was sampled before and after the different main process and disinfection process; then, the diversity and abundance of ARGs and mobile genetic genes (MGEs, helping the horizontal transfer of ARGs) in wastewater of different treatment stages were determined by a real-time high-throughput quantitative PCR (HT-qPCR) system.

Analysis of M6A associated lncRNAs in prognosis and immune response of NSCLC patients.

Distinguishing between N6-methyladenosine (m6A)-associated long noncoding RNAs (lncRNAs) is crucial in non-small-cell lung cancer (NSCLC) patients. In this research, the prognosis and immunotherapeutic response of lncRNAs and m6A in NSCLC were examined. lncRNAs related to m6A were identified using co-expression analyses, and their prognostic impact on patients with NSCLC was assessed using univariate Cox regression analysis.

Comparison between immunotherapy efficacy in early non-small cell lung cancer and advanced non-small cell lung cancer: a systematic review.

Background: Currently, immunotherapy is widely used in the treatment of various stages of non-small cell lung cancer. According to clinical experience and results of previous studies, immunotherapy as neoadjuvant therapy seems to exhibit better efficacy against early resectable non-small cell lung cancer as compared to advanced lung cancer, which is often defined as unresectable non-small cell lung cancer. However, this observation has not been established in clinical studies.

Host stimulator of interferon genes is essential for the efficacy of anti-programmed cell death protein 1 inhibitors in non-small cell lung cancer.
