    The over-activated CSN5/FBXO3/MALT1 regulatory axis is correlated with the poor prognosis of NSCLC patients. A The mRNA level of MALT1, CSN5 and FBXO3 in NSCLC tissues (n = 16) and normal lung tissues (n = 14) was analyzed by GEO database (GSE40275). B Representative IHC images of MALT1 in tissue specimens. Quantification of MALT1 levels according to IHC scores in right panel. C The protein level of MALT1 in bronchial epithelium cell BEAS-2B and NSCLC cell lines was determined by immunoblotting. D Relapse free survival Kaplan–Meier curves of NSCLC patients based on the expression of MALT1 were analyzed via PrognoScan database (GSE31210) and the cut-point value of MALT1 expression was 0.81. E Overall survival rate of NSCLC patients with high CSN5 expression was lower than those with low CSN5 expression. The data was analyzed by PrognoScan database (GSE13213) and the cut-point value of CSN5 expression was 0.68. F Relapse free survival Kaplan–Meier curves of NSCLC patients based on the expression of FBXO3 were analyzed via PrognoScan database (GSE31210) and the cut-point value of FBXO3 expression was 0.64. G, H The correlation between MALT1 and CSN5 in normal lung tissues ( G ) and NSCLC tissues ( H ), respectively. The data was analyzed by GEPIA website based on TCGA database. I Simplified model of over-activated CSN5/FBXO3/MALT1 regulatory axis promoting NSCLC malignancy via NF-κB pathway. In NSCLC, overexpressed CSN removes NEDD8 from Cullin-RING to inhibit E3 ligase FBXO3 activity resulting in reduction of MALT1 ubiquitination which contributes to MALT1 stabilization and keeps NF-κB activating, while small molecular inhibitor MI-2 irreversibly inhibits it. Each experiment was performed in triplicate and data are presented as mean ± SD. One-way ANOVA and Paired-Samples T test were used to analyze the data (* p < 0.05, ** p < 0.01, *** p < 0.001)

The interactions of pGBKT7-53/pGADT7-T and pGBKT7-Lam/pGADT7-T were used as positive and negative controls, respectively. Yeast transformants carrying the indicated constructs were plated onto selective plates supplemented without Leu/Trp/His/Ade to assay growth. (B) A model depicting the protein–protein interactions among the Csn subunits of the Csn complex. The black lines indicate the direct interaction. (C) Western blot showing the interaction between Csn5 and Csn6 by using a coimmunoprecipitation (co-IP) assay. Total proteins isolated from the strains bearing GFP-Csn5 and/or Flag-Csn6 (input) and the proteins eluted from the anti-GFP beads (elution) were detected using anti-Flag antibody. GAPDH was used as an internal control. (D) Western blot showing the interaction between Csn5 and Csn1 by using a co-IP assay. (E) Western blot showing the interaction between Csn5 and Csn2 by using a co-IP assay. (F) Western blot showing the interaction between Csn5 and Csn3 by using a co-IP assay. (G) Western blot showing the interaction between Csn5 and Csn4 by using a co-IP assay. (H) Western blot showing the interaction between Csn5 and Csn7 by using a co-IP assay.

    Article Snippet: The GFP-Csn5 were immunoprecipitated from total proteins of tested strains using anti-GFP agarose beads (ChromoTek, Martinsried, Germany) and Flag-Csn1 was detected from proteins co-purified with GFP-Csn5 to verify the association between Csn5 and Csn1.

    The localization of the Csn subunits in hyphae of F. graminearum . (A) Micrographs showing the localization of GFP-Csn5 in hyphae of F. graminearum after growth in liquid complete medium (CM) for 16 h. H1-mCherry was used to visualize the nuclei. Bar = 5 μm. A line scan graph was generated at the indicated position (arrow) to show the relative localization of GFP-Csn5 (green) and H1-mCherry (red). (B) Micrographs showing the localization of six Csn subunits in hyphae of F. graminearum . Bar = 5 μm.

    Transcriptome profiles governed by Csn5 in F. graminearum. (A) Volcano plots showing genes in which the expression was significantly upregulated (red-colored) and downregulated (blue-colored) in the Δ csn5 mutant compared to the wild-type strain PH-1 ( P < 0.05, fold change ≥2.0) under nutrient-rich conditions [complete medium (CM)] or toxin induction conditions [trichothecene biosynthesis induction (TBI) medium]. (B) Venn diagrams showing the number of genes in which the expression was significantly upregulated (left panel) or downregulated (right panel) in the Δ csn5 mutant compared with the wild-type strain PH-1 under both nutrient-rich conditions and toxin induction conditions. (C) Enriched gene ontology (GO) terms in genes with downregulated transcripts in the Δ csn5 mutant under nutrient-rich conditions.

    Regulation of DON production by the Csn complex. (A) Heatmap comparing the relative transcriptional abundance of TRI genes in the wild-type strain or Δ csn5 mutant in three independent replicates using transcriptomic analysis. WT, wild type. MT = Δ csn5 mutant. The transcription levels of TRI genes in the replicate 1 of the wild-type strain were set to 1.0. (B) Bar charts showing the relative transcriptional abundance of TRI genes in the wild-type strain or indicated mutant strains using quantitative real-time PCR (qRT–PCR). (C) Bar charts showing DON production in 7-day-old TBI cultures of the indicated strains. (D) Western blot analysis of Tri1 protein levels in tested strains expressing Tri1-GFP with the anti-GFP antibody. GAPDH was used as an internal control. (E) Fluorescence signals of Tri1-GFP were detected in the tested strains after growth in liquid TBI medium for 48 h. Bar = 10 μm. Error bars indicate the standard deviation from three independent experiments. Statistical analysis was performed via Student’s t -test. A triple asterisk indicates statistical significance with p < 0.001.
