Figure Lengend Snippet: Overexpression of DNPH1 in human breast tumors (A) DNPH1 mRNA expression in various breast cancer subtypes was analyzed in published microarray data. Mean with standard deviation and statistical significance compared to normal breast tissue are indicated; ∗∗∗∗, p < 0.0001 (one-way ANOVA, Tukey’s multiple comparisons test). (B) High (top quartile) DNPH1 mRNA levels predict reduced survival. Data derived from published microarray experiments ; p < 0.0001 (log rank test). (C) DNPH1 protein expression in human breast cell lines assayed by Western blotting. (D) Examples of immunohistochemical staining with DNPH1 antibodies on matching normal and cancerous breast tissue. Scale bars, 0.1 mm. (E) DNPH1 protein expression was measured by immunohistochemistry in 20 matching normal and cancerous human breast tissues; two-tailed, paired t test.

Article Title: ARTS Confers Chemoresistance of Breast Cancer by Inducing Apoptosis-Dependent Autophagy via Livin–MDM2–p53 Pathway

doi: 10.34133/research.1086

Figure Lengend Snippet: ARTS is predominantly expressed in resistant breast cancer tissues and promotes chemoresistance in breast cancer cells. (A) Screening workflow for chemoresistance-related genes in breast cancer. DEGs from GSE288073 are shown in a volcano plot, followed by overlap with apoptosis-related and mitochondria-related gene sets, yielding 12 DEGs; ARTS was prioritized and evaluated by Kaplan–Meier survival analysis for postchemotherapy prognosis. FPKM, fragments per kilobase of transcript per million mapped reads. (B) Representative hematoxylin and eosin (H&E) and IHC images of ARTS in paired pre- and post-NAC samples from NAC-sensitive and NAC-resistant patients. The black arrow indicates a residual small cluster of tumor cells. Scale bar, 50 μm. (C) Association of ARTS protein with MPG score and Ki-67 in pre- and post-NAC samples. (D) Kaplan–Meier analyses of OS and RFS stratified by ARTS protein (low versus high). (E and F) MTT and (G and H) colony formation assays in sh-Ctrl versus sh-ARTS MDA-MB-231 and Flag versus Flag–ARTS MCF-7 cells under the indicated treatments. * P < 0.05; *** P < 0.001. ns, not significant.
