Decoding population PM exposure in China: interplay of emissions, meteorology, and inequality (2013-2020).

Over the past decade, China has significantly improved air quality by integrating environmental policies with economic growth. Yet, environmental inequality remains a major challenge to social equity and sustainable development. This study examines the socioeconomic impacts of PM exposure using population data from 1,317 county towns across 32 provinces (2013-2020), employing meteorological normalization and population-weighted exposure indices.

Identification of novel umami peptides from Pleurotus ostreatus and their umami-enhancing effects through virtual screening, sensory evaluation, and molecular simulation.

This investigation identified umami-enhancing peptides derived from Pleurotus ostreatus and elucidated their interaction mechanisms via molecular simulations. We identified six peptide candidates with potential umami-enhancing properties through a comprehensive virtual screening process. Sensory evaluations revealed that these umami peptides vary in taste characteristics, with detection thresholds ranging from 0.

Scavenger receptors: An auspicious therapeutic target for autoimmune diseases.

Scavenger receptors (SRs) belong to a large receptor family expressed on immune and non- immune cells. Initially, SRs are regarded as removers able to recognize and clear modified lipoproteins; However, it is now realized that they are pattern recognition receptors (PRRs) that identify damage-associated molecular pattern (DAMP) and pathogen-associated molecular patterns (PAMPs). The wide range of ligands that bind to SRs demonstrates their diverse functions, including pathogen clearance, lipid transport, cellular differentiation, and signaling pathway activation.

Regioselective [3 + 2]/[4 + 2] Annulations of α-Nitrosostyrenes with Triazines.

Reported herein are the regioselective [3 + 2]/[4 + 2] annulations of α-nitrosostyrenes with hexahydro-1,3,5-triazines, which provide five- and six-membered heterocycles in moderate yields under mild reaction conditions. Compared to previous reports, this unusual [3 + 2] annulation features the use of rhodium catalysts to control the regioselectivity of α-nitrosostyrenes, generated in situ from α-bromooximes . Meanwhile, the [4 + 2] annulation process was primarily regulated by 1,4-dioxane and temperature.

ANXA1 promotes intrahepatic cholangiocarcinoma proliferation and growth by regulating glutamine metabolism through GOT1 stabilization.

Background: Intrahepatic cholangiocarcinoma (ICC) is a malignant tumor with a poor prognosis, marked by a postoperative recurrence rate of 50-60% and a 5-year survival rate of 8-30%. Abnormal tumor metabolism, particularly, amino acid metabolism, plays a key role in malignant progression. However, the molecular mechanisms linking amino acid metabolism to ICC progression remain unclear.

Sciellin inhibits senescence and promotes pancreatic cancer progress by activating the notch signaling pathway.

Pancreatic cancer (PC) incidence is increasing annually globally, and the five-year survival rate of patients with PC is approximately 10%. Cellular senescence is a regulatory mechanism against cancer that prevents tumor development by inhibiting the proliferation of damaged or abnormal cells. However, the mechanisms underlying cellular senescence in PC is unclear.

Senescence-related circRNA circHIF-1α is associated with pancreatic cancer progression.

Recently, there has been growing interest in the role of circular RNAs (circRNAs) in the progression of human cancers. Cellular senescence, a known anti-tumour mechanism, has been observed in several types of cancer. However, the regulatory interplay of circRNAs with cellular senescence in pancreatic cancer (PC) is still unknown.

TMOD3 accelerated resistance to immunotherapy in KRAS-mutated pancreatic cancer through promoting autophagy-dependent degradation of ASCL4.

The high prevalence of KRAS mutations in pancreatic cancer (PC) is widely acknowledged and results in the resistance of targeted ferroptosis therapy and immunotherapy. Herein, via a CRISPR/Cas9 library screen, the effects of ferroptosis agonists were increased in KRAS-mutant PC cells upon knockout of tropomodulin 3 (TMOD3), while these effects were not observed in KRAS-wild-type cells. Increased levels of TMOD3 were found in PC tissues, particularly in those with KRAS mutations.

C5b-9 promotes ferritinophagy leading to ferroptosis in renal tubular epithelial cells of trichloroethylene-sensitized mice.

Trichloroethylene (TCE) is a common environmental contaminant that can cause a severe allergic reaction called TCE hypersensitivity syndrome, which often implicates the patient's kidneys. Our previous study revealed that C5b-9-induced tubular ferroptosis is involved in TCE-caused kidney damage. However, the study did not explain how tubule-specific C5b-9 causes free iron overload, a key event in ferroptosis.

C5a/C5aR1 axis as a key driver promotes epithelial-to-mesenchymal transition in airway epithelial cells in silica nanoparticles-induced pulmonary fibrosis.

Previous studies have shown that silica nanoparticles (SiNPs) exposure can affect the respiratory, cardiovascular, reproductive and other systems, with the lung being the primary target organ for the direct effect, causing damage with a central feature of pulmonary inflammation and fibrosis. However, the underlying mechanisms of pulmonary fibrosis due to SiNPs are not fully understood. The aim of the study was to investigate the role of complement anaphylatoxin C5a in SiNPs-induced pulmonary fibrosis.

A novel method to extend viability and functionality of living heart slices.

Living heart slices have recently emerged as a powerful experimental model for fundamental cardiac research. By retaining the structure and function of the native myocardium while maintaining the simplicity of cell culture models, heart slices can be easily employed in electrophysiological, pharmacological, biochemical, and structural investigations. One single heart yields many slices (>20 slices for rodents, >100 slices for porcine or human hearts), however due to the low throughput of most assays and rapid slice degeneration within 24 h of preparation, many slices remain unused and are discarded at the end of the preparation day.

IP3R-dependent mitochondrial dysfunction mediates C5b-9-induced ferroptosis in trichloroethylene-caused immune kidney injury.

Patients with occupational medicamentose-like dermatitis due to trichloroethylene often suffer from immune kidney injury. Our previous study reveals that C5b-9-dependent cytosolic Ca overload-induced ferroptosis is involved in trichloroethylene sensitized kidney injury. However, how C5b-9 causes cytosolic Ca rise and the specific mechanism whereby overloaded Ca induces ferroptosis remain unknown.

Mechanisms involved in nicotinamide adenine dinucleotide phosphate (NADPH) oxidase (Nox)-derived reactive oxygen species (ROS) modulation of muscle function in human and dog bladders.

Roles of redox signaling in bladder function is still under investigation. We explored the physiological role of reactive oxygen species (ROS) and nicotinamide adenine dinucleotide phosphate (NADPH) oxidase (Nox) in regulating bladder function in humans and dogs. Mucosa-denuded bladder smooth muscle strips obtained from 7 human organ donors and 4 normal dogs were mounted in muscle baths, and trains of electrical field stimulation (EFS) applied for 20 minutes at 90-second intervals.

Enhancing de novo ceramide synthesis induced by bisphenol A exposure aggravates metabolic derangement during obesity.

Objective: Exposure to bisphenol A (BPA) has been shown to increase the prevalence of obesity and its related insulin resistance (IR). Ceramide is a sphingolipid known to facilitate the production of proinflammatory cytokines and subsequently exacerbate inflammation and IR during the progression of obesity. Here, we investigated the effects of BPA exposure on ceramide de novo synthesis and whether increased ceramides aggravate adipose tissue (AT) inflammation and obesity-related IR.

HMGB 1 acetylation mediates trichloroethylene-induced immune kidney injury by facilitating endothelial cell-podocyte communication.
