Liver X receptors (LXRs) are master regulators of cholesterol homeostasis and immune responses. Here, we evaluated the therapeutic potential of chronic pharmacological modulation using the potent synthetic agonist T0901317 (T0) in the hSOD1<sup>G93A</sup> mouse model. To assess both long-term functional outcomes and the underlying molecular mechanisms, T0 was administered via two distinct experimental designs. In a longitudinal cohort treated from postnatal day 60 (P60) until the humane endpoint, T0-treated SOD1G93A mice exhibited delayed body weight loss and sustained improvements in neuromuscular strength and motor coordination. Critically, this continuous treatment preserved functional motor unit connectivity, delayed overall clinical progression, and significantly extended median lifespan. While protective in both sexes, the survival benefit was slightly more pronounced in females. Molecular characterization revealed that the early systemic T0 administration successfully engaged canonical LXR targets in the spinal cord, driving a significant transcriptional upregulation of cholesterol efflux pathways and suppressing pro-inflammatory signaling cascades. This response induced a lipid partitioning, evidenced by a significant accumulation of cholesterol esters within the central nervous system, potentially mitigating lipotoxicity. Taken together, these findings demonstrate that T0901317 treatment exerts a significant beneficial effect, highlighting the pharmacological modulation of these lipid and inflammatory networks as a promising therapeutic strategy for ALS.</div></div>","PeriodicalId":19159,"journal":{"name":"Neurotherapeutics","volume":"23 5","pages":"Article e01062"},"PeriodicalIF":7.4,"publicationDate":"2026-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148892245","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

KMT5C mRNA levels were evaluated in a publicly available pediatric gliomas database using bioinformatic analysis. Investigation of SUV4–20H2 and H4K20me3 expression was performed in a cohort of 43 pediatric astrocytoma tissues by immunohistochemistry. Their functional role and mechanism of action was investigated in pediatric glioma cell lines by using the substrate-competitive inhibitor of SUV4-20, A-196. Cell viability, apoptosis and migration were assessed using XTT, cleaved PARP, and wound healing assays, respectively. Effects of treatment on H4K20 methylation, DNA damage, mitotic stress [Polo-like kinase (PLK1) expression], and invasion markers (N-cadherin, β-catenin expression) were examined by western immunoblotting. KMT5C mRNA was significantly enriched in pediatric high-grade astrocytomas compared to low-grade tumors. A significant elevation of SUV4–20H2 and H4K20me3 expression was detected in astrocytoma tissues indicating epigenetic dysregulation contributing to malignancy. Treatment with A-196 reduced cell proliferation of pediatric glioma cell lines and induced apoptosis in a dose-dependent manner. It further impaired cell migration, accompanied by reduced N-cadherin and β-catenin expression. Mechanistically, inhibition of SUV4-20 depleted H4K20me3, inducing chromatin destabilization, replication-associated DNA damage and was associated with increased PLK1 expression, consistent with activation of a mitotic stress response.

In this study, a PSD rat model was used to investigate the pathophysiological mechanisms in left PFC through behavioral testing, biochemical assays, and pharmacological interventions targeting protein kinase C alpha (PKCα) and protein interacting with C kinase 1 (PICK1)-GluA2 binding. The results demonstrated that PSD reduced membrane GluA2 in left PFC. Mechanistically, PICK1 participated in the phosphorylation of GluA2 by PKCα, which in turn facilitated the reduction of membrane GluA2. Crucially, both inhibition of PKCα and disruption of PICK1-GluA2 binding rescued membrane GluA2 in left PFC without affecting total GluA2 expression and alleviated depressive-like behaviors of PSD rats.
