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.
