ETV4 transcriptionally controls key genes involved in DNA replication of NSCLC cells. A) Functional analysis showing the top KEGG pathways that are significantly associated with down‐regulated genes in H1299, H1703, and H358T si‐ETV4 groups normalized to negative control (NC) siRNA groups by Human Microarray ( GSE137445 ). B) Clustering analysis showing the gene signature is enriched in the DNA replication pathway. C) IGV tracks showing the enrichment of ETV4 at the promoter region of MCM2, ‐4, ‐5, ‐10, and ORC1 from ChIP‐seq signals of A549‐shETV4 cells transfected with Flag‐ETV4 plasmids. D) ChIP‐PCR analysis for endogenous or exogenous ETV4 binding to the promoter region of MCM2, ‐4, ‐5, ‐10, and ORC1 genes in H1299 cells using anti‐ETV4 antibody or H358‐ETV4 cells using anti‐Flag antibody. E) Schematic depicting the core motif of ETV4 binding with its target genes, the wild‐type luciferase reporter constructs, and the mutations in the putative ETV4‐binding sites (mut‐1 or mut‐2 type) of MCMs/ORC1 promoter region. F–J) The wild‐type luciferase reporter plasmids of MCMs (ORC1) were co‐transfected along with ETV4, ETV4‐DBD deletion plasmid, or the empty vector into HEK293T cells. The constructed luc‐MCMs (ORC1)‐mut‐1 or ‐mut‐2 type plasmids were co‐transfected along with ETV4 plasmid or the empty vector into HEK293T cells. Relative luciferase activity was normalized against Renilla luciferase activity, respectively (mean ± SD; n = 4; ordinary one‐way ANOVA with Tukey's multiple comparisons test). **** p < 0.0001; ### p < 0.001, #### p < 0.0001.

$CARM1 deficiency suppresses XPF–ERCC1 accumulation at DNA damage sites and delays CPD removal. ( A ) CARM1 KO inhibited CPD removal ability. The defect of CPD removal was rescued by exogenous CARM1-WT but not by inactivated CARM1-AAA. Data are shown as the mean ± SD of biological three independent experiments (multiple comparisons: two-way ANOVA, ** P < .01, **** P < .0001). ( B ) CARM1 KO and KD cells showed increased sensitivity to UV light. Biological three independent experiments were performed. Error bars represent SD * P < .05, ** P < .01, and *** P < .001 (Student’s t -test). ( C ) Accumulation of XPC at local UV-exposed sites was not different between siCt and siCARM1, but XPF and ERCC1 accumulations were inhibited by siCARM1. Representative images of immunostaining for XPC and XPF and phosphor HBO1 and ERCC1 in local UV-irradiated HeLa cells. HeLa cells were irradiated with 50 J m −2 UV through an 8-μm pore membrane and fixed after 30 min of incubation. The mean intensity of the irradiated area was divided by the intensity of the non-irradiated area of the same nucleus and expressed as a relative intensity increase from the baseline (%). Scale bars, 5 μm. Data are shown as the mean (unpaired t -test). ( D ) CARM1 interacts with XPF in HEK293 cells. ( E ) XPF interacts with CARM1 in DOX-induced XPF stable expression cells and 293 cells. ( F ) XPF WT-Myc and GST-CARM1 interact in a GST pull-down assay. When XPF WT-Myc overexpressed in HEK293 cells was pulled down using GST-CARM1 expressed and purified in E. coli , XPF WT-Myc specifically co-precipitated. *An unknown E. coli protein that is co-purified when GST-CARM1 is purified from E. coli . ( G ) CARM1 KD cells showed decreased total protein content of XPF and decreased chromatin localization. XPF amounts were corrected for ORC2. The amount of XPF in each fraction is expressed as relative amount (%) to the siCt soluble fraction without UV. Biological five independent experiments were performed. Error bars represent SD. * P < .05 and *** P < .001 (Student’s t -test).$
