To identify rare or low-frequency variants within genes that confer susceptibility to otitis media, exome sequence data of 287 individuals from 243 families were analyzed. Identified variants were tested for co-segregation with otitis media in family members. Genome sequence data from a case-control cohort was imputed and analyzed for association of specific genes with otitis media. Single-cell RNA-sequence data of identified genes were noted in acutely infected mouse middle ears. Thirty-three variants within 24 genes co-segregated with otitis media in 28 families, of which 18 variants were considered pathogenic or likely pathogenic. An additional 81 variants in 21 of the same genes were identified in 83 unrelated probands with otitis media. Of the 24 genes, 12 were associated with otitis media in mouse models, while 15 genes were replicated from previous human studies. A common variant EYA4 c.829G > A was associated with OM in the case-control cohort. Using network analysis, 22 of the 24 genes were connected in a subnetwork enriched in various signaling pathways, Th1/Th2/Th17 cell differentiation, and viral infections. Majority (87.5%) of the identified genes were expressed in mouse middle ear cells, with differential expression after acute infection. The identification of novel genes and variants for susceptibility to otitis media will be useful in future risk screening and clinical management in children that require a more personalized approach due to poor response to standard treatments. KEY MESSAGES: Thirty-three variants in 24 genes were identified in 28 families with otitis media. Eighteen of these variants within 10 genes were considered (likely) pathogenic. A common variant EYA4 c.829G > A was associated with OM in a case-control cohort. The novel genes were differentially expressed in mouse middle ear post-infection.

The molecular mechanism and effects of elevated Cu on cytoskeletal dynamics in liver fibrogenesis are not clear. Here, we tested the regulation of hepatic cytoskeleton and fibrogenesis with respect to Cu overload in WD. Atp7b<sup>-/-</sup> (knockout) mice with established liver disease, hepatocyte-specific Atp7b△<sup>Hep</sup> knockout mice without fibroinflammatory disease, and the age-and sex-matched controls were compared using Western blotting, real-time quantitative reverse transcription PCR (qRT-PCR), immunohistochemical (IHC) staining and transcriptomics (RNA-sequencing) analysis. In Atp7b<sup>-/-</sup> mice with developed liver disease, there is a significant increase in cytoskeletal protein expression with a reduction in α-tubulin acetylation. In these mice before the onset of liver pathology, no significant changes in cytoskeletal nor hepatic stellate cell activation are observed. As hepatic copper levels rise, an increase in cytoskeletal proteins with a decrease in acetylated-α-tubulin/α-tubulin ratio occurs. RNA-sequencing, qRT-PCR, and immunostaining confirm that the tubulin is upregulated at the transcriptional level and hepatocytes are the primary source of early tubulin increases before fibrosis. An increase in α-tubulin with a decrease in α-tubulin acetylation via Hdac6 and Sirt2 induction facilitates fibrosis as reflected by concomitant increases in desmin and α-SMA immunostaining in Atp7b<sup>-/-</sup> mice at 20 weeks. Moreover, strongly positive correlations between α-tubulin and α-tubulin deacetylase with the expression of liver fibrosis markers are observed in animal and human WD. Hepatocyte-specific Atp7b△<sup>Hep</sup> mice lack significant changes in tubulin as well as fibrosis despite hepatic steatosis. This study provides evidence that microtubule destabilization causes cytoskeletal rearrangement and facilitates hepatic stellate cell (HSC) activation and fibrosis in the murine model of WD. KEY MESSAGES: Hepatic cytoskeleton system is induced in Wilson disease. Hepatic microtubules acetylation is dysregulated in murine Wilson disease. Microtubules destabilization is positively associated with liver fibrosis in Wilson disease.

Among the types of hepatoma, hepatocellular carcinoma (HCC) is the most important pathological type. For patients with early-stage HCC, the curative treatment is tumor resection. However, early diagnosis and treatment of HCC are difficult; the disease progresses rapidly, and the prognosis is poor. Due to the current limited treatment options for advanced HCC, the identification of new targeted agents is critical for the development of novel approaches to HCC treatment. Histone deacetylases (HDACs) is a protease that removes acetyl groups from histone lysine residues in proteins, and it plays an important role in the structural modification of chromosomes and the regulation of gene expression. Abnormally expressed HDACs can promote tumorigenesis by inducing biological processes such as cell proliferation, migration, and apoptosis inhibition. Since HDACs activity is upregulated in HCC, treatment regimens specifically inhibiting various HDACs have shown good efficacy.

The bioinformatics analyses revealed positive correlations between FLOT1 expression and infiltration of M2 macrophages, neutrophils, dendritic cells, and CD4 memory T cells. Furthermore, elevated FLOT1 expression was associated with a poor prognosis in lung cancer patients. Analysis of tumor and adjacent non-tumor tissues from 53 lung cancer patients revealed significantly higher immunohistochemical staining of FLOT1 in tumor tissues, showing positive correlation with the staining intensity of PD-L1. Additionally, staining intensities for markers of M2 macrophages (Arg1), CD4 memory T cells (CD4), dendritic cells (CD83), and neutrophils (CD177) were significantly higher in tumor tissues with high FLOT1 levels. Silencing of FLOT1 was induced in two lung cancer cell lines. Co-culturing in conditioned media of the FLOT1-silenced cancer cells led to reduced chemotactic migration and M2 skewing of macrophages in vitro. Using xenograft models, we observed that FLOT1 silencing weakened tumorigenic activity of A549 cells in mice and reduced M2 macrophage infiltration in tumors. SWI/SNF related BAF chromatin remodeling complex subunit C1 (SMARCC1) was identified as a transcription factor that activated FLOT1 transcription by binding to its promoter. Knockdown of SMARCC1 in lung cancer cells similarly reduced the migration and M2 polarization of macrophages as well as weakened tumorigenesis in mice. However, these effects were counteracted by FLOT1 overexpression. Further analysis of the downstream effectors of the SMARCC1/FLOT1 cascade revealed the enrichment of these factors in ferroptosis-related pathways. Mechanistically, SMARCC1 knockdown led to a decreased GSH:GSSG ratio and increased lipid peroxidation in macrophages, while FLOT1 overexpression restored these changes. Transmission electron microscopic observation revealed typical features of ferroptosis-resistant mitochondria following SMARCC1 knockdown, including fragmented or reduced cristae and increased outer membrane integrity. These mitochondrial changes were mitigated by FLOT1 overexpression. In conclusion, SMARCC1 promotes immune evasion in lung cancer by activating FLOT1 transcription. This activation enhances recruitment and M2 polarization of macrophages, and increases PD-L1 expression, reduces ferroptosis. These findings provide valuable insights into the molecular mechanisms of immune evasion and suggest potential therapeutic targets for lung cancer treatment.

This study evaluated the expression patterns of the ANXA1 and NLRP3 proteins in human skin samples obtained from patients with atopic dermatitis (AD) and in mice with ovalbumin (OVA)-induced experimental AD. Furthermore, the in vitro effect of the ANXA1 mimetic peptide Ac2-26 on IL-4-stimulated human keratinocytes was evaluated. IL-4-stimulated keratinocytes were treated with Ac2-26 (a mimetic peptide of ANXA1) in two different concentrations: 5 and 25 ng/mL. Additionally, some cells were treated with the pan-formyl peptide receptor antagonist Boc2 at a concentration of 10 µM, administered 15 min before Ac2-26. The NLRP3 protein demonstrated intense immunoreactivity in both murine and human AD skin samples, with NLRP3 and ANXA1 exhibiting particularly high coexpression in keratinocytes. A significant increase in ANXA1 and NLRP3 transcripts was observed in AD skins (GSE16161 study). ANXA1 transcript levels were elevated in the AD epidermis relative to the non-lesional epidermis, while NLRP3 transcript levels were reduced in the AD epidermis (GSE120721 study). The Ac2-26 treatment reduced the proliferation rate of IL-4-stimulated keratinocytes, an effect abolished by Boc2 and IL-1β and ROS production. In conclusion, our findings indicate that ANXA1 plays a role in regulating NLRP3 activation in keratinocytes, contributing to the pathogenesis of AD.
