- This study explored the role of ubiquitin-specific peptidase 17-like family member 2 (USP17L2) and sphingosine kinase 1 (SphK1) in regulating macrophage autophagy and pyroptosis via the TRAF6-ULK1-NLRP3 signaling axis during Mp lipid exposure. Using in vitro and in vivo models, the study examines protein expression, cytokine levels, and cellular processes. Mechanistic explorations were performed on the mycoplasma pneumoniae pneumonia (MPP) models. Mp lipid treatment significantly upregulated SphK1 and USP17L2 expression in MH-S cells while promoting proinflammatory cytokine secretion, ROS production, and activation of pyroptosis and autophagy. Silencing SphK1 suppressed Mp lipid-induced macrophage autophagy, pyroptosis, and activation of the TRAF6-ULK1 signaling axis. Co-IP confirmed direct interaction between SphK1 and TRAF6, with SphK1 inducing ULK1 ubiquitination. USP17L2 was a specific deubiquitinating enzyme for SphK1, and the two proteins interacted. Silencing USP17L2 significantly reduced inflammatory infiltration in lung tissue, neutrophil recruitment in bronchoalveolar lavage fluid, and bacterial load in MPP mice. Concurrently, it suppressed the expression of autophagy-related molecules, pyroptosis-related molecules, and proinflammatory factors in lung tissue. In conclusion, USP17L2 stabilizes SphK1 through deubiquitination modification and activates the TRAF6-ULK1-NLRP3 signaling axis, thereby promoting macrophage autophagy and pyroptosis and exacerbating MPP damage. Silencing USP17L2 blocks this regulatory pathway, inhibiting excessive inflammatory responses and cell death. - Source: PubMed

Liu LianhongXie JianyongWu BichenDing NiuZhang JinMeng YanniChen Yanping - Aberrant activation of the Wnt/β-catenin signaling pathway is a hallmark of colorectal cancer (CRC). Here, we identify the deubiquitinating enzyme USP17 as a critical regulator of β-catenin stability and activity in CRC. We demonstrate that USP17 directly interacts with and deubiquitinates β-catenin, preventing its degradation and enhancing its stability. CRISPR/Cas9-mediated knockdown of USP17 in CRC-derived cell lines significantly reduced β-catenin levels and suppressed epithelial-mesenchymal transition (EMT), as evidenced by distinct morphological changes and altered expression of classical EMT markers. USP17 depletion reduced the proliferation of CRC cell lines and impaired CRC tumor growth in vivo. Conversely, USP17 overexpression in immortalized rat enterocytes elevated β-catenin levels and enhanced KRAS-induced cell proliferation. RNA sequencing and quantitative proteomic analysis of USP17-depleted CRC cells revealed significant suppression of the transcriptional coactivator function of β-catenin, impacting key oncogenic-related pathways. Our findings establish USP17 as a key regulator of β-catenin signaling and highlight its potential as a candidate therapeutic target in CRC. - Source: PubMed

Comorbidity with autism spectrum disorder (ASD) and other neurodevelopmental conditions has been observed. The genetic etiology is highly heterogeneous. Here, we present three unrelated individuals with CAS and concomitant fine and gross motor involvement but different genetic variants of interest. The DNA of the cases and their parents underwent exome sequencing and variant filtering. Using publicly available data, the genes of interest derived from the variants were investigated for expression rates in the early developing brain. Known and putative protein-protein interactions among the genes of highest confidence were identified. Of 28 variants in 28 different genes, variants with highest confidence were situated in , , , , and . High gene expression rates in the developing cerebellum were observed for and . These genes encode the α5 and β1 subunits, respectively, of the heterotrimeric extracellular laminin-511 complex, a major component of the basal membrane in many tissues. Network analysis of the five high-confidence genes required expansion with only one additional gene, , to arrive at a fully connected network. The addition of four genes and inclusion of transcriptional regulation as an additional edge type allowed connecting all 28 genes of interest to arrive at a dense connectome with 32 nodes and 73 edges, representing a network enrichment with value of < 0.001, suggesting that our network has significantly more interactions than expected under random conditions. We conclude that high levels of genetic heterogeneity converge on a functional gene network governed by stimulation of cells through laminin-511 with shared direct or regulatory expression in the developing cerebellum and phenotypic overlaps of CAS, ASD, and other neurodevelopmental disorders. - Source: PubMed

While genome-wide association studies have identified multiple common variants associated with sporadic endometriosis, the contribution of rare variants in familial endometriosis remains understudied. This scoping review aims to collate the published literature on familial endometriosis and systematically curate the genetic findings reported for familial endometriosis, including details of genetic variants, gene functions, and their associated biological pathways, to explore the monogenic inheritance of this disorder. - Source: PubMed

The potential molecular mechanisms underlying breast cancer metastasis remain to be further elucidated. In this study, via database analysis, we revealed that the deubiquitinase josephin domain containing 2 (JOSD2) was abnormally amplified in patients with metastatic breast cancer, and was significantly negatively correlated with patient prognosis. By integrating data from the Gene Expression Omnibus (GEO) database and Kyoto Encyclopedia of Genes and Genomes (KEGG) signaling pathway enrichment analysis, we found that the transforming growth factor beta (TGF-β) signaling pathway was significantly activated in breast cancer patients with increased JOSD2 expression. Further studies revealed that JOSD2 interacted with and stabilized SMAD family member 4 (SMAD4) by removing polyubiquitin chains. Inhibition of JOSD2 by RNA interference effectively inhibited the metastasis of breast cancer cells both in vitro and in vivo. In conclusion, our study not only reveals the role of JOSD2 in promoting breast cancer metastasis for the first time, but also indicates promising directions for the future development of deubiquitinase inhibitors, which could yield significant therapeutic benefits. Nevertheless, extensive research and development are required to fully realize this potential. - Source: PubMed
