      Glycosylation of Tetraspanin CD151 Defines the Invasive Phenotype of Human Breast Cancer Cells

      Integrated N-glycosylation status of CD151 contributes to invasive activity in breast cancer cells. There are mainly three types of N-glycosylation status in CD151: oligomannose-type, complex-type, and no-glycosylation. The oligomannose-type glycan inhibits the association with integrin α3, while the complex-type glycan and the no-glycosylation form do not inhibit the association with integrin α3. The invasive activity of the breast cancer cells is integrated in these states. Non-glycosylated forms exhibit strong invasion activity that defines the invasive phenotype of breast cancer patients.

        Biochemical Modifications of Homocysteine Drive Neutrophil Extracellular Trap Formation in Ischemic Stroke

        Peripheral neutrophils upon stimulation with homocysteine and its modifications induce NETosis and DNA damage in an ERK/AKT/PAD4-dependent signaling pathway. Hyperhomocysteine mouse models exhibit elevated NETs markers, platelet activation, reduced motor function, and neuronal damage, and administration of anti-NETs agents reverses the deteriorative effects. Stroke subjects display elevated homocysteine, NETs components, and autoantibodies against homocysteinylated serum albumin.

          FOXM1 Facilitates NSCLC Tumorigenesis Through the Transcriptional Regulation of UBE2C

          FOXM1, a key transcriptional driver, and UBE2C, a mitotic regulator, are co-overexpressed in NSCLC. FOXM1 transcriptionally activates UBE2C, promoting tumor proliferation, invasion, and progression. FAM64A enhances FOXM1 stability, further amplifying oncogenic signaling. Targeting the FAM64A/FOXM1/UBE2C axis suppresses tumor growth, revealing a critical pathway and promising therapeutic target in NSCLC.

            Kynurenine Pathway Dysregulation Impairs Podocyte Morphology and Bioenergetics In Vitro and Leads to Glomerular Dysfunction

            The enzymes of the kynurenine pathway participate in the catabolism of TRP, where they generate metabolites known as kynurenines, which are considered biologically active. Using a transgenic zebrafish line, we showed that systemic changes in the kynurenine pathway lead to edema and proteinuria, both signs of an impaired glomerular filtration barrier. Additionally, inhibition of the pathway in cultured podocytes resulted in alterations to the cytoskeleton, increased cell detachment, and changes in redox status and mitochondrial function.

                ADAM8 Destroys the Endothelial Barrier and Promotes Leukocyte Extravasation to Aggravate Hepatic Ischemia–Reperfusion Injury

                Hepatic ischemia–reperfusion injury (HIRI) is a local aseptic inflammatory response driven by innate immunity, and it can severely damage liver function. In this work, we found that ADAM8 expression was increased in the liver tissues of HIRI mice, which was also correlated with the progression of liver damage. Suppression of ADAM8 abated HIRI development by disrupting the endothelial barrier, increasing endothelial permeability, accelerating leukocyte extravasation, and the inflammatory response.

                  Lipoxin A4 Regulates M2 Macrophage-Derived Exosomal miR-25-5p to Protect Cell Pyroptosis in Bronchopulmonary Dysplasia

                  In premature infants with BPD treated with LXA4, circulating monocytes are reprogrammed and polarized into M2-Mφs and then migrate into the lungs. The M2-exo released by M2-Mφs, which is rich in miR-25-5p, downregulates the PI3K/AKT signaling pathway by acting on the target gene NRBP2, thereby inhibiting the pyroptosis of AT2. The secretion of GSDMD-N and inflammatory factors from the latter is reduced, alleviating the destruction of AT2 and inflammatory responses, and improving BPD-induced lung injury.

                    HMGB2 Deficiency in Bone Marrow Mesenchymal Stem Cells Promotes Age-Related Osteoporosis by Inhibiting Osteoblast Differentiation via Inflammatory Factors

                    High mobility group box 2 (HMGB2) is essential in osteoporosis patients and can be used to treat osteoporosis by promoting osteogenic differentiation of bone marrow mesenchymal stem cells (BMSCs). HMGB2 knockdown in senescent BMSCs inhibited osteogenic differentiation, and overexpression of HMGB2 promoted osteogenic differentiation. Mechanistically, HMGB2 can regulate the transcription of IL-6 and IL-1β through TUG1 and directly regulate the transcriptional level of TNF-α (Graphical abstract image by Figdraw).

                        Loss of the RNA Binding Protein HuR in Early Murine Limb Mesenchyme Does Not Affect Development but Leads to Impaired Bone Homeostasis in Adulthood

                        The RNA-binding protein HuR (Elavl1) is essential for limb development. In germline HuR knockouts, apical ectodermal ridge signaling is lost, though mesenchymal signals persist. Mesenchyme-specific HuR deletion does not affect embryonic limbs, but adult mutants are affected and exhibit markedly reduced trabecular bone density. These findings point toward a critical role for HuR expression in nonmesenchymal tissues during limb development, but its presence in mesenchymal-derived cells is important for the healthy homeostasis of the mature limb skeleton.

                          Near-haploid HAP1-SPT cells, which cannot synthesize sphingolipids de novo, undergo a drastic reduction in sphingolipid content when grown under low FBS conditions. To compensate, they remodel their lipidome by increasing ether-linked phospholipids and adjusting glycerophospholipid saturation. Despite these changes, plasma membrane biophysical properties remain stable, highlighting lipidome plasticity as a key mechanism for preserving membrane homeostasis under sphingolipid depletion.

                            Oral ingestion of microplastics (MPs) results in the deposition of MPs in the pancreas. Further, MPs can be absorbed by pancreatic stellate cells, stimulate the activation of cellular ROS, further activate NF-κB and TGF-β signaling pathways, and increase the levels of fibrosis-related proteins and collagen. Meanwhile, exposure to MPs alters gut microbial diversity, with downregulation of bacteria in the Bacteroidota phylum and upregulation of bacteria in the Verrucomicrobiota phylum.

                                  This study reveals that FOXA1, as a transcription factor, binds to the promoter of the HILPDA gene and significantly upregulates its expression. High HILPDA expression promotes lipid droplet accumulation, which not only provides additional energy and protection for cancer cells and enhances their resistance to anoikis, but also directly facilitates cell migration and invasion, thereby driving the metastasis of lung adenocarcinoma.

                                    This graphical abstract shows that LPS downregulates SESN2, leading to suppressed GPX4 activity, increased ROS, lipid peroxidation, and inflammation. SESN2 overexpression reverses these effects by activating the Nrf2/SLC7A11/GPX4 axis, reducing MDA and 4HNE levels, preserving redox balance, and alleviating ocular symptoms including hypopyon and retinal vascular inflammation.

Heat stress triggered physiological changes including mitochondrial dysfunction, indicated by reduced ATP production, and disrupted expression of key mitochondrial markers (HSPD1 and ATP5F1). Heat-induced oxidative stress was also evident (decreased intracellular GSH), which subsequently caused DNA damage, senescence, and inflammatory activation. Metabolic derangement was also evident following heat treatment.

                                              ATP-dependent membrane flickering in healthy red blood cells (RBCs) facilitates parasite invasion by maintaining cytoskeletal plasticity. In contrast, PKLR-deficient RBCs exhibit suppressed flickering due to impaired glycolysis, leading to increased membrane rigidity that acts as a mechanical barrier against Plasmodium entry. This biophysical phenotype reveals a potential nonimmunological defense mechanism in PKLR enzymopathy.

                                                Schematic diagram of copper-induced cell death in LUAD. Elesclomol, as a copper ionophore, promotes copper influx into LUAD cells. This copper influx leads to cellular copper overload. Copper overload induces ER stress in LUAD cells. ER stress upregulates PCK2, which in turn inhibits the tricarboxylic acid (TCA) cycle. Collectively, these pathways orchestrate the cellular responses to excessive copper levels in LUAD cells, highlighting the complex interplay between copper homeostasis, metabolic reprogramming, and cell death mechanisms.

                                                  Swim Exercise Mitigates BCAA-Induced Atrial Remodeling and AF Susceptibility via Inhibition of Bax-Mediated Mitochondrial Apoptosis

                                                  Atrial fibrillation (AF) is the most common sustained arrhythmia. Although elevated branched-chain amino acids (BCAA) are linked to cardiovascular disease, their specific role in AF was not well defined. This study shows that BCAA supplementation induces atrial remodeling and increases AF susceptibility in mice, with swim exercise reversing these effects. Mechanistically, besides causing insulin resistance, BCAA supplementation promoted AF by activating Bax-mediated apoptosis, thus identifying a critical mechanism behind this relationship.

                                                    EPZ5676 inhibits DOT1L-mediated H3K79me2, promoting mouse embryonic lung branching morphogenesis. Treatment with EPZ5676 enhances the proliferation and differentiation of lung epithelial progenitor cells into mature epithelial lineages. EPZ5676 synergizes with FGF7 to drive pulmonary epithelium tissue enlargement and secondary branching. This epigenetic modulation promotes branching morphogenesis in mouse embryonic lungs, underscoring the therapeutic potential of EPZ5676 in lung development and related disorders.

A functional cross talk between the signaling pathways of 2-AG and the bioactive sphingolipid sphingosine 1-phosphate (S1P) has been identified here in endometriosis. Indeed, the specific S1P receptor S1P3, whose expression is augmented by 2-AG, is crucial for transducing the biological action of the endocannabinoid. Notably, the functional cross talk was found to be independent of both isoforms of the S1P biosynthetic enzyme, sphingosine kinase (SK1/SK2).

                                                            This study demonstrates that MYST1 knockdown attenuates neointima formation in rat carotid artery injury models and suppresses SMC proliferation and migration in cellular models. Mechanistically, MYST1 promotes neointima formation by stabilizing KLF4 via acetylation, which inhibits SRF-TAZ interaction, drives pathological SMC phenotypic switching, and ultimately accelerates vascular remodeling.

In addition, this regulatory mechanism has also been validated in mice.

Metabolomic profiling showed widespread accumulation of medium- and long-chain acylcarnitines in preeclamptic cases versus normotensive controls, representing maladaptive and adaptive phenotypes, respectively. Adaptive fetal haplotypes, consisting of genes associated with lipid metabolism (CPT2/LRP8, EXOC4, LIPG) identified via integrative haplotype scores (iHS), were associated with healthier placental metabolic profiles.

Using murine orthotopic LT models, we performed graft transcriptomic profiling. Rejection was characterized by 2560 differentially expressed genes, highlighting T cell receptor signaling and cytokine interaction. Hub genes (e.g., Cd8a, Gzmb, Pdcd1, Lag3) revealed CD8+ T cell cytotoxicity and exhaustion were pivotal, confirmed by elevated PD-1/TIM-3 and granzyme B. This dynamic balance provides new insights into rejection mechanisms and potential therapeutic targets.

                                                                              Schematic illustrating the regulation of APP degradation by neuronal GSK3β in 5 × FAD mice. In the 5 × FAD model, GSK3β promotes APP degradation. Conditional knockout of Gsk3β impairs this process, resulting in APP accumulation. This leads to increased Aβ plaque formation and enhanced neuroinflammatory responses.

Mendelian randomization identified COL6A2 and PTGIR as protective genes, while SERPINE1 and VIM were risk genes. Validation in a rat model confirmed PTGIR expression and fibrosis markers, suggesting PTGIR as a protective factor against atrial fibrosis.

Mechanistically, a high-glucose environment reduced TRPV6 expression and TRPV6-mediated Ca2+ influx, which eventually inhibited the migration of keratinocytes through a CaM-AKT-FN1 pathway.

We studied PD-L1 expression on sEVs in HUVECs and explored its modulation in response to IL-1β, a key player in the immune response and involved in the pathogenesis of several diseases. sEVs were collected by sequential ultracentrifugation from HUVEC (±IL-β) and characterized by NTA, electron microscopy and WB. The workflow highlights that IL-1β leads to the release of a greater quantity of sEVs-PD-L1+.
