Figure Lengend Snippet: (A) Kaplan–Meier analysis of overall survival in the TCGA-UCEC cohort stratified by NOTCH3 copy-number using upper-versus-lower quartile grouping. Tumors with elevated NOTCH3 copy-number exhibited significantly reduced overall survival compared with tumors harboring low copy-number. (B) Kaplan–Meier analysis of overall survival stratified by NOTCH3 RNA expression using upper-versus-lower quartile grouping. NOTCH3 RNA expression demonstrated only a modest, nonsignificant association with outcome. (C) Kaplan–Meier analysis of overall survival according to NOTCH3 mutation status. No significant association between NOTCH3 mutation status and overall survival was observed. Log-rank P values are indicated on each panel. Tables beneath Kaplan–Meier plots indicate the number of patients at risk at the indicated time points (days).

Figure Lengend Snippet: (A) Schematic model illustrating canonical NOTCH3 signaling and the proposed mechanism of AuR action. Following ligand-dependent NOTCH3 activation, NICD3 forms a transcriptional activation complex with RBPJ at canonical NOTCH-responsive promoters, including HES1 and HES4 . AuR reduces RBPJ occupancy at canonical NOTCH-responsive promoters. (B–D) Representative RBPJ chromatin immunoprecipitation (ChIP) assays in RL95-2 (B), ARK-1 (C), and AN3CA (D) cells following treatment with DMSO or 2.5 µM AuR. RBPJ occupancy at the HES1 and HES4 loci was measured by qPCR and normalized to input chromatin. Bead-only controls were included to assess nonspecific background enrichment. (E) Representative nonlinear regression curves from one experiment showing CDDP response in AN3CA cells treated with increasing concentrations of CDDP in the absence or presence of 0.75 or 1.0 µM AuR. Relative proliferation was normalized to untreated controls. (F) Replicate-level quantification of relative CDDP IC50 values from independent biological replicates across AuR concentrations, including 0.75, 1.0, and 1.5 µM AuR conditions. IC50 values were normalized to the no-AuR condition. Data are presented as mean ± SEM. Statistical significance in panel F was determined using one-way ANOVA with multiple-comparison correction. ns, not significant; *, P < 0.05; **, P < 0.01; ***, P < 0.001.

(B–D) Dose-response analysis of AuR response in Ctrl KD, NOTCH3A KD, and NOTCH3C KD cells. Representative nonlinear regression curves are shown at left, with replicate-level area under the curve (AUC) quantification shown at right. (E) Dose-response analysis of CDDP response in AN3CA cells following NOTCH3 depletion. Representative nonlinear regression curves are shown at left, with replicate-level AUC quantification shown at right. Relative proliferation values were normalized to vehicle-treated controls. Data are presented as mean ± SEM. AUC values were calculated from replicate dose-response curves.
