- Parkinson disease (PD), the second most common neurodegenerative disorder, is pathologically linked to dysregulated autophagy, a conserved lysosomal degradation pathway. Current conventional PD therapies are often limited by significant side effects, underscoring the demand for alternative treatment strategies. Drug repurposing of FDA-approved compounds represents a promising approach to address this unmet clinical need. Here, by integrating clinical data analysis, we identified an association between autophagy impairment and specific PD patient subtypes, suggesting that ULK1-dependent autophagy activation may offer therapeutic benefit. Through systematic screening for autophagy induction and neuroprotective activity, we identified econazole, a known imidazole antifungal, as a promising candidate. Econazole exhibited robust therapeutic effects across multiple PD models, including MPTP-induced zebrafish and mouse models, as well as SNCA mutant mouse models. Notably, its efficacy was dependent on functional autophagy, as autophagy inhibition abrogated its beneficial effects. Mechanistically, econazole activated ULK1, enhanced autolysosome formation, and promoted clearance of SNCA aggregates. Mouse brain microarray analysis indicated that econazole-activated ULK1 suppresses MAP3K12/DLK-MAPK8/JNK-MAPK9/JNK2-mediated neuronal apoptosis. Further phosphoproteomic profiling uncovered a novel ULK1-HSPA8/Hsc70 interaction that promotes LAMP1 and LAMP2 activation and enhances lysosomal function. This ULK1-HSPA8 complex additionally activated the BECN1 (beclin 1) complex to facilitate autophagosome formation. Together, our findings highlight a clinical data-guided drug repurposing approach that identifies econazole as a potent autophagy activator with therapeutic efficacy in ULK1-linked PD models, opening new avenues for PD treatment.: 3-MA: 3-methyladenine; ACTB: actin beta; ATG: autophagy related; AUC: area under the curve; BafA1: bafilomycin A1; BECN1: beclin 1; CMA: chaperone-mediated autophagy; DA: dopamine; DOPAC: 3,4-dihydroxyphenylacetic acid; Econ: econazole; GFP: green fluorescent protein; HEK-293T: human embryonic kidney 293T; HSPA8: heat shock protein 8 family A (Hsp70) member 8; HVA: homovanillic acid; JUN: Jun proto-oncogene, AP-1 transcription factor subunit; KSEA: kinase-substrate enrichment analysis; LAMP: lysosome associated membrane protein; MAP1LC3/LC3: microtubule associated protein 1 light chain 3; MAP2K: mitogen-activated protein kinase kinase; MAP3K12: mitogen-activated protein kinase kinase kinase 12; MAPK: mitogen-activated protein kinase; MPP+: 1-methyl-4-phenylpyridinium; MPTP: 1-methyl-4-phenyl-1,2,3,6-tetrahydropyridine; PD: Parkinson disease; RB1CC1: RB1 inducible coiled-coil 1; RFP: red fluorescent protein; RMSD: root mean square deviation; SEM: standard error of the mean; SNCA: synuclein alpha; SQSTM1: sequestosome 1; SYP: synaptophysin; TFEB: transcription factor EB; TH: tyrosine hydroxylase; ULK1: unc-51 like autophagy activating kinase 1; WT: wild-type. - Source: PubMed

Zhang JinJin WenkeFu YuqiZhen YongqiChen YanmeiLiu WeiHuang WeiWang ZhiwenZhu Hong-PingYang Qian-QianZhan GuZhao QianPeng ChengZhang LanHan BoLiu Bo - Traumatic brain injury (TBI) triggers a sustained neuroinflammatory response driven by activated microglia, which contributes to secondary injury and long-term neurological dysfunction. Therapeutic reprogramming of microglial activation from a pro-inflammatory (M1-like) to a reparative (M2-like) phenotype represents a promising strategy; however, the lack of cell-specific targeting within an injured brain has limited clinical translation. Here, we developed a targeted gene-editing nanotherapy to modulate post-traumatic innate immune responses. Lipid nanoparticles (LNPs) encapsulating CRISPR-Cas12a components were engineered to target mitogen-activated protein kinase-9 (MAPK9), a key regulator of pro-inflammatory signaling, and were conjugated with an Iba-1 antibody (Iba-1-CRISPR-LNPs) to enable selective targeting of microglia. , MAPK9 editing in primary macrophages inhibited M1 polarization and promoted an M2-like phenotype, leading to reduced production of proinflammatory cytokines. In a TBI mouse model, intranasal administration of Iba-1-CRISPR-LNPs achieved efficient delivery to the injured brain, with selective localization in Iba-1+ microglia. MAPK9 CRISPR targeting significantly attenuated microglial activation, reduced central and peripheral inflammatory responses, and decreased pro-inflammatory cytokine levels. Importantly, this approach demonstrated a favorable safety profile, with no detectable toxicity across major organs. Collectively, these findings establish a non-viral, intranasal CRISPR-based strategy for cell-specific modulation of neuroinflammation following TBI. Targeted genome editing of MAPK9 effectively reprograms microglial activation and attenuates acute inflammatory responses, highlighting its potential as a promising and translationally relevant therapeutic platform for TBI and related neuroinflammatory disorders. - Source: PubMed

Kara GoknurAli YaqoobLópez-Espinosa JessicaPark PeterHolcomb MorganFlinn HannahTaylor NoahGalbraith TylerLeonard FransiscaVillapol Sonia - Infection of the large yellow croaker () embryo cell line YCE1 with megalocytivirus strain FD201807 leads to accumulation of capsid-deficient viral intermediates within intracellular vesicles at 48 h post-infection (a phenotype associated with non-lytic egress), which coincides with the initial peak of viral genomic copies. To characterize the host molecular response during this critical stage, we performed time-course RNA sequencing at 24, 48, 96, and 144 hpi. Integrated analysis identified 6661 differentially expressed genes (DEGs) and 1138 differential alternative splicing (DAS) events affecting 892 genes, with DAS event abundance peaking at 48 h. DAS genes in autophagy and Golgi vesicle transport pathways, both integral to animal innate immunity, were significantly enriched exclusively at this timepoint, featuring novel mutually exclusive exon (MXE) isoforms in (Golgi-associated PDZ and coiled-coil motif containing) and (RAD50 interactor 1). Weighted gene co-expression network analysis (WGCNA) of DEGs identified (mitogen-activated protein kinase 9) and (microtubule-associated protein 1 light chain 3 alpha) as hub genes within modules enriched for autophagy-related functions. Separate co-expression analysis of DAS genes revealed , , and as hub genes, with exhibiting only a single linkage to . These findings implied concurrent transcriptional and virus-induced host splicing regulation of vesicle-associated innate defense pathways and suggest that splicing-derived features may serve as potential candidates for diagnostics or prevention against megalocytivirus disease in . - Source: PubMed

Zheng ZaiyuChi HongshuLiu XiaodongChen XiuxiaPan YingGong Hui - This study explored the potential mechanisms of action of Gualou-Xiebai-Baijiu Decoction (GXBD) in the treatment of atherosclerosis (AS) by integrating computational analyses with preliminary animal experiments. The putative targets of blood-absorbed components in GXBD were obtained and then intersected with AS-related targets, followed by protein-protein interaction network construction, core target identification, and GO and KEGG enrichment analyses. Targets presenting potential causal associations with AS were determined with Mendelian randomization (MR) analyses. Binding stability between candidate compounds and key targets was evaluated with molecular docking and molecular dynamics (MD) simulations. Finally, a mouse model of AS was established for in vivo validation. A total of 379 targets of six blood-absorbed components in GXBD and 1975 AS-related targets were identified, among which 154 were overlapping genes and 64 were further defined as core targets. Enrichment analysis results indicated the involvement of pathways including fluid shear stress, PI3K-Akt, and focal adhesion. Among the targets of GXBD, , , , , , and showed significant causal associations with AS, with determined as the key target. Molecular docking and MD simulations demonstrated that Chrysoeriol glucuronide might stably interact with . In ApoE mice, GXBD treatment significantly decreased expression in the aorta, increased serum l-Arg and NO levels, improved lipid profiles, and reduced aortic plaque burden. These findings provide preliminary evidence that GXBD may ameliorate AS-related pathological changes via the /l-Arg/NO pathway, offering mechanistic insights into the multicomponent actions of GXBD in AS treatment and highlighting further validation directions. - Source: PubMed

Chen YulinHu KaiHe YingyingLi RunzhenMeng YanhuiNie ShaTang Yaoping - Aggressive behavior in Muscovy ducks (Cairna moschata) has become a predominant concern in intensive farming systems, leading to reduced animal welfare and production losses. To unravel the molecular mechanisms underlying this behavior, transcriptomic profiling was performed on the hypothalamus, a key regulatory hub for aggressive responses. A total of 120 healthy 60-day-old female Muscovy ducks were continuously monitored for 24 h/day over one month using Media Recorder 2.0 software. Based on instantaneous and continuous behavioral observations, the ducks were categorized into three groups: aggressor (Experimental group I, actively attacking conspecifics), victim (Experimental group II, receiving aggression), and non-aggressive (Control group, no aggressive interactions). Hypothalamic tissues were collected from each group (n = 4 per group) for Illumina HiSeq 2000 high-throughput transcriptome sequencing. Functional annotation and enrichment analysis of differentially expressed genes (DEGs) were performed using Gene Ontology (GO) and Kyoto Encyclopedia of Genes and Genomes (KEGG) databases, followed by quantitative real-time PCR (qRT-PCR) validation. GO analysis identified 626 DEGs in the aggressor group and 649 DEGs in the victim group compared to the control group, with 26 DEGs directly involved in aggressive behavior regulation. Integration of GO and KEGG annotations revealed 69 candidate genes associated with aggressive behavior, enriched in two GO terms (behavior [GO:0007610] and sensory perception of pain [GO:0019233]) and the ERBB signaling pathway (map04012). qRT-PCR validation of 14 randomly selected candidate genes (e.g., NPY, ERBB4, MAPK9, PRDM12) confirmed that their expression patterns were consistent with transcriptomic data, verifying the reliability of the sequencing results. These findings provide novel insights into the molecular genetic basis of aggressive behavior in Muscovy ducks and lay a foundation for developing targeted strategies to mitigate aggression in intensive farming systems. - Source: PubMed
