Figure 1. Comparison of mRNA and protein <t>EPB41L3</t> levels in lung-tissue-derived ﬁbroblasts between 14 IPF patients and 10 controls. Expression of EPB41L3 mRNA (normalized to that of β-actin) was measured using (A) RT-PCR, (B) densitometry, and (C) real-time PCR (log (2−∆∆Ct). Protein expression of EPB41L3 (normalized to that of β-actin) was measured using (D) Western blot and (E) densitometry. The Mann–Whitney U test was performed to identify the statistical signiﬁcance between IPF and control groups. Data are medians and quantiles, and * p < 0.01. (F) Correlations between the RT-PCR and Western blot band intensities was analyzed using Spearman’s correlation coefﬁcient. (See Figure S1 for RT-PCR and original Western blot images.)

Figure 2. Changes in mRNA and protein of EPB41L3 and EMT-related genes expressed by A549 cells after stimulation with TGF-β. A549 cells were cultured with or without 5 ng/mL of TGF-β1 for 24, 48, and 72 h. The EPB41L3-, N-cadherin-, E-cadherin-, and COL1A1-to-β-actin ratios were measured using (A) real-time PCR, (B) Western blot, and (C) densitometry of protein bands. They were normalized to β-actin and expressed as ratios. All experiments were performed separately six times, and the representative images are shown. Data are mean ± SE of the six independent experiments. Basal levels (0 h) were excluded from statistical analysis. Signiﬁcant differences between groups were evaluated using two-way ANOVA with Bonferroni multiple comparisons test. * p < 0.05 and ** p < 0.01 compared to TGF-β1-stimulated cells. Black bars: untreated control group, bars with diagonals: TGF-β1-treated group. (See Figure S2 for original Western blot images).

Fig. 9. Schematic working model of FOXA1 O-GlcNAcylation–mediated breast cancer metastasis. O-GlcNAcylation at T432/S441/S443 shapes the FOXA1 interac- tome, especially triggers the recruitment of transcriptional repressor MECP2, consequently stimulates FOXA1 chromatin-binding sites switch to chromatin loci of adhe- sion-related genes, including EPB41L3 and COL9A2, and thus promotes breast cancer proliferation and metastasis both in vitro and in vivo.

Protein expression of EPB41L3 (normalized to that of β-actin) was measured using (D) Western blot and (E) densitometry. The Mann–Whitney U test was performed to identify the statistical signiﬁcance between IPF and control groups. Data are medians and quantiles, and * p < 0.01. (F) Correlations between the RT-PCR and Western blot band intensities was analyzed using Spearman’s correlation coefﬁcient. (See Figure S1 for RT-PCR and original Western blot images.)

Figure Lengend Snippet: Figure 2. Changes in mRNA and protein of EPB41L3 and EMT-related genes expressed by A549 cells after stimulation with TGF-β. A549 cells were cultured with or without 5 ng/mL of TGF-β1 for 24, 48, and 72 h. The EPB41L3-, N-cadherin-, E-cadherin-, and COL1A1-to-β-actin ratios were measured using (A) real-time PCR, (B) Western blot, and (C) densitometry of protein bands. They were normalized to β-actin and expressed as ratios. All experiments were performed separately six times, and the representative images are shown. Data are mean ± SE of the six independent experiments. Basal levels (0 h) were excluded from statistical analysis. Signiﬁcant differences between groups were evaluated using two-way ANOVA with Bonferroni multiple comparisons test. * p < 0.05 and ** p < 0.01 compared to TGF-β1-stimulated cells. Black bars: untreated control group, bars with diagonals: TGF-β1-treated group. (See Figure S2 for original Western blot images).

Changes in EPB41L3 and EMT-related gene expression after EPB41L3 transfection in the presence and absence of 5 ng/mL of TGF-β1 for 48 h. Expression of mRNA and protein normalized to β-actin levels were measured using (A-1–A-4) real-time PCR, (B) Western blot, and (C-1–C-4) densitometry of protein bands. They were normalized to β-actin and expressed as ratios. Independent experiments were analyzed using densitometry. All experiments were performed separately six times, and the represen- tative images are shown. Data are mean ± SE of 6 independent experiments. Signiﬁcant differences between groups were evaluated using two-way ANOVA with Bonferroni multiple comparisons test. * p < 0.05 and ** p < 0.01. EMT: epithelial–mesenchymal transition, Lv: Lentivirus, black bar: control group, open bar: EPB41L3-overexpressing group. (See Figure S3 for original Western blot images).
