Integration of Metabolomics and Proteomics Reveals the Molecular Characterization of High-Altitude Hyperuricemia.

Hypobaric hypoxia-induced hyperuricemia (HUA) is a major health challenge for high-altitude populations, yet its molecular mechanisms remain poorly understood. This study employed metabolomic and proteomic profiling of a high-altitude cohort (10 HUA patients and 10 matched controls) to address this gap. HUA patients exhibited significantly elevated uric acid (UA), creatine kinase, and lactate dehydrogenase levels alongside reduced platelet counts.

An erythroid-biased FOS hematopoietic multipotent progenitor subpopulation contributes to adaptation to chronic hypoxia.

Hypoxia imposes notable stress on organisms and even causes tissue damage; however, the cellular and molecular mechanisms underlying hypoxic adaptation and maladaptation are elusive. Here, we performed single-cell RNA sequencing to analyze hematopoietic stem and progenitor cells (HSPCs) and erythroid cells in a mouse model of high-altitude polycythemia (HAPC) mimicking long-term high-altitude hypoxia exposure. We identified a distinct erythroid-biased multipotent progenitor subset, FOS MPP, characterized by a unique responsiveness to interferon (IFN) signaling, which expands under hypoxia conditions.

TEDML: a new machine learning (ML) approach for predicting thyroid eye disease and identifying key biomarkers.

Thyroid eye disease (TED) features immune infiltration and metabolic dysregulation. Understanding these processes and identifying potential biomarkers are crucial for improving diagnosis and treatment. To this end, immune cell infiltration was analyzed and gene set variation analysis (GSVA) was conducted on the GSE58331 dataset to identify differences between TED and normal tissues.

Protraction of a second molar and a mesially-impacted third molar into the adjacent first-molar extraction site through mini-implant anchored Albert protraction loop with the aid of alveolar ridge augmentation.

Protraction of a mandibular second molar to substitute the adjacent missing first molar is challenging in clinical practice. In this case report, we demonstrated a 21-year-old patient with an untreatable periapical lesion of the mandibular right first molar. The adjacent mandibular second molar had normal root length and the third molar was mesially-impacted.

The present study aimed to investigate the therapeutic potential of Osmundacetone (Osu), a natural plant product, for the treatment of rheumatoid arthritis (RA). The study revealed that Osu effectively reduced arthritis-induced swelling and bone destruction, as well as alleviating inflammation-related factors and oxidative stress in animal models. We focused the mechanism exploration on its regulatory mechanism on osteoclastogenesis in the next investigation.

Background: The incidence of mandibular first molar impaction is less than 0.01%, and there are no standard treatment guidelines. Orthodontic traction can be chosen as a treatment plan in some circumstances.

Intermittent high altitude hypoxia induced liver and kidney injury leading to hyperuricemia.

About 140 million people worldwide live at an altitude above 2500 m. Studies have showed an increase of the incidence of hyperuricemia among plateau populations, but little is known about the possible mechanisms. This study aims to assess the effects of high altitude on hyperuricemia and explore the corresponding mechanisms at the histological, inflammatory and molecular levels.

SIRT1 regulates mitochondrial fission to alleviate high altitude hypoxia inducedcardiac dysfunction in rats via the PGC-1α-DRP1/FIS1/MFF pathway.

High-altitude exposure has been linked to cardiac dysfunction. Silent information regulator factor 2-related enzyme 1 (sirtuin 1, SIRT1), a nicotinamide adenine dinucleotide-dependent deacetylase, plays a crucial role in regulating numerous cardiovascular diseases. However, the relationship between SIRT1 and cardiac dysfunction induced by hypobaric hypoxia (HH) remains unexplored.

Corrigendum: Sestrin2 protects against hypoxic nerve injury by regulating mitophagy through SESN2/AMPK pathway.

Isoquercitrin attenuates the osteoclast-mediated bone loss in rheumatoid arthritis via the Nrf2/ROS/NF-κB pathway.

An excess of osteoclastogenesis significantly contributes to the development of rheumatoid arthritis (RA). Activation of the nuclear factor erythroid-2 related factor 2 (Nrf2) and nuclear factor kappa B (NF-κB) ligand (RANKL)-induced reactive oxygen species (ROS)-to-NF-κB signaling cascade are important mechanisms regulating osteoclastogenesis; however, whether Nrf2 is involved in RANKL-induced NF-κB activation is controversial. Isoquercitrin, a natural flavonoid compound, has been shown to have Nrf2-dependent antioxidant effects inprevious studies.

Sestrin2 protects against hypoxic nerve injury by regulating mitophagy through SESN2/AMPK pathway.

Hypoxia induced by high altitude can lead to severe neurological dysfunction. Mitophagy is known to play a crucial role in hypoxic nerve injury. However, the regulatory mechanism of mitophagy during this injury remains unclear.

LAMC2 regulates proliferation, migration, and invasion mediated by the Pl3K/AKT/mTOR pathway in oral.

Background: Oral squamous cell carcinoma (OSCC) is a common malignant tumor. Recently, Laminin Gamma 2 (LAMC2) has been shown to be abnormally expressed in OSCC; however, how LAMC2 signaling contributes to the occurrence and development of OSCC and the role of autophagy in OSCC has not been fully explored. This study aimed to analyze the role and mechanism of LAMC2 signaling in OSCC and the involvement of autophagy in OSCC.

Citrus tangerine pith extract alleviates hypoxia-induced ileum damage in mice by modulating intestinal microbiota.

Visitors to high altitude are susceptible to hypoxia-induced acute intestinal mucosal barrier injury and severe gastrointestinal disorders, which are life-threatening. Citrus tangerine pith extract (CTPE) is rich in pectin and flavonoids and has been proved to enhance intestinal health and improve gut dysbiosis. In this study, we aim to explore the protective effect of CTPE on ileum injury induced by intermittent hypobaric hypoxia in a mouse model.

To study the protective effects of resveratrol (RSV) on cardiac function in rats with high altitude hypobaric hypoxia and its mechanisms. Thirty-six rats were randomly divided into control group, hypobaric hypoxia group (HH) and hypobaric hypoxia + RSV group (HH+RSV) according to the random number, 12 rats in each group. Rats in the HH and HH+RSV groups were subjected to chronic long-term high altitude hypobaric hypoxia intervention for 8 weeks in a hypobaric chamber at a simulated altitude of 6 000 m for 20 h / d.

[Construction and evaluation of a gradient stress model of PC12 cells induced by corticosterone].

A gradient stress model of PC12 cells induced by corticosterone was established to provide a basis for the evaluation and regulation of cell stress. The effect of corticosterone on cell viability was observed by measuring PC12 cell viability at different concentrations of corticosterone (0~1 000 μmol/L) after different intervention times (8~48 h) to screen the cell models for optimal intervention conditions. Key stress indicators (MDA, SOD, NADH, LDH) were measured spectrophotometrically and microscopically to evaluate the models.
