Figure Legend Snippet: Xenopus oocytes injected either with ( A, B ) human ZIP14 or ( E, F ) human ZIP8 cRNA were incubated with either ( A, E ) ⁶⁵Zn or ( B, F ) ⁵⁵Fe in the presence of ( A, E ) 50 µM or ( B, F ) 10 µM PPTD for 30 min at 22 °C. Radioactivity was measured as described under Methods . Data are normalized against DMSO-treated transporter-expressing controls, and presented as mean ± standard deviation (S.D.) (n=3 independent experiments). Similarly, (C, D) TREx-hZIP14 or (G, H) TREx-hZIP8 cells were treated with Tet (1 μg/mL) for 24 h, followed by incubation either with ( C, G ) ⁵⁴MnCl₂ or (D, H) ¹⁰⁹CdCl₂ in the presence of PPTD at the indicated concentrations for 1 h. Radioactivity was measured as described under Methods . The data (mean + SD) represent results from three independent experiments. Statistical significance was determined using Student’s t -test (A, B, E, F) or one-way ANOVA followed by Dunnett’s post hoc test (C, D, G, H). (* p < 0.05, ** p < 0.01, *** p < 0.005, **** p < 0.001, ***** p < 0.0005).

Figure Legend Snippet: A Structural predictions of ZIP14-PPTD complexes using both monomeric (left) and dimeric (right) forms of human ZIP14 by AlphaFold3. Magenta circles indicate the predicted PPTD binding sites. Protein models are colored by structure prediction confidence estimated by predicted Local Distance Difference Test (pLDDT) (dark blue, pLDDT >90, light blue, pLDDT of 90-70, yellow, pLDDT of 70-50, orange, pLDDT <50). B Structural overlay of the ZIP14-PPTD and ZIP14-zinc complexes, predicted using AlphaFold3. PPTD and zinc bind in close proximity within the dimerized ZIP14 protein. magenta: PPTD, purple: zinc, blue: His347 and His380 residues. C Prediction of human ZIP14 amino acid residues interacting with PPTD by Protein–Ligand Interaction Profiler and AlphaFold3 (Supplementary Table 5). magenta: PPTD, green dot line: pi-stacking, yellow dot line: salt bridges, gray dot line: hydrophobic interactions, blue line: hydrogen bond. D Asp348 is essential for ZIP14-mediated zinc transport. Xenopus oocytes were injected with human ZIP14 (WT), ZIP14 (D348L), ZIP14 (D348N) cRNA, or water (wi, control). The uptake assay was performed with 10 μM ZnSO 4 including a trace amount of radioactive tracer in the presence of 50 μM PPTD for 30 min at 22 °C. Radioactivity was measured as described under Methods . Statistical analysis was performed by one-way ANOVA followed by Tukey’s multiple comparison test. (*** p < 0.001). All data are shown as mean ± S.E.M. (n= 6 to 9 oocytes).

Figure Legend Snippet: A Comparison of structural simulations of the human ZIP14 (WT)-PPTD complex (upper) and the ZIP14 (S343Y)-PPTD complex (lower). Substitution of Serine 343 with Tyrosine (S343Y) reduces the size of the PPTD-binding pocket within ZIP14, as indicated by the dotted red circle in the mutant structure. magenta: PPTD. B Serine 343 is essential for ZIP14-mediated zinc transport. Xenopus oocytes were injected either with human ZIP14 (WT), ZIP14 (S343Y) cRNA, or water (wi, control). The uptake assay was performed with 10 μM ZnSO 4 including a trace amount of radioactive tracer in the presence of 50 μM PPTD. Radioactivity was measured as described under Methods . All data are shown as mean ± S.E.M. (n= 6 to 9 oocytes). C Structural overlay of five modeled complexes of PPTD bound to human ZIP14 with aspartic acid to leucine substitution at position 443 (D443L). In the four models, PPTD consistently occupies an internal binding region of ZIP14 (indicated by the blue arrow), while one model shows PPTD associating with the protein surface (the red arrow). This variation suggests that the D443L mutation may disrupt the stable binding of PPTD to ZIP14. D Aspartic acid at position 443 contributes to the sensitivity of ZIP14 to PPTD. After preincubation with indicated concentrations of PPTD, Xenopus oocytes injected with cRNA encoding wild-type human ZIP14 (WT) or the D443L mutant were incubated with 10 μM ZnSO 4 including a trace amount of radioactive tracer in the presence of the same concentrations of PPTD for 30 min at 22 °C. The IC₅₀ values for ZIP14 WT and D443L were 8.9 μM and 19.0 μM, respectively. Radioactivity and IC₅₀ values were determined as described under Methods . E The ZIP14 D443L mutant retains transport activity but loses sensitivity to PPTD. Xenopus oocytes were injected with cRNA encoding either wild-type human ZIP14 (WT) or the D443L mutant. The uptake assay was performed with 10 μM ZnSO 4 including a trace amount of radioactive tracer in the presence of 20 μM PPTD. Radioactivity was measured as described under Methods . Statistical analysis was performed using one-way ANOVA followed by Tukey’s multiple comparison test (*** p < 0.001). All data are shown as mean ± S.E.M. (n= 6 to 9 oocytes).

Figure Legend Snippet: A Schematic overview of the experimental workflow for PPTD administration to the mouse model of cancer cachexia. B Effects of PPTD administration on body weight loss in the cancer cachexia model. Mice were administered PPTD via drinking water at either 0.1 g/L (low-dose) or 1.0 g/L (high-dose). C PPTD extends survival in the cancer cachexia model. Mice were administered 0.1 g/L (low dose, blue line) or 1.0 g/L (high dose, red line) PPTD through drinking water. Survival was analyzed using the Kaplan-Meier method. Black line: water-treated control group. Survival curves were compared using the Kaplan–Meier method and log-rank test ( p < 0.05 is considered significant). D PPTD delays the onset of cachexia symptoms. Mice were administered 0.1 g/L (low-dose) or 1.0 g/L (high-dose) PPTD via drinking water. The day on which each group first exhibited ≥10% body weight loss or death is shown. Statistical analysis was performed using one-way ANOVA followed by Dunnett’s post hoc test (* p < 0.05). E PPTD improves locomotor activity in a cancer cachexia model. The locomotor of individual mice (n = 3 per group) was recorded on the 16th day of PPTD administration and analyzed using ImageJ (Supplementary Movie 7), as described under Methods . The results are presented as box plots with gray and blue boxes representing the H₂O control group and the PPTD-treated group (0.1 g/L), respectively. Each point represents an individual mouse. Statistical significance was assessed using Welch’s t-test to compare total distances between groups (* p < 0.05). F Working model: Inflammatory stimuli induce ZIP14 expression, promoting metal-induced cytotoxicity that contributes to cancer cachexia (left). The ZIP14 inhibitor PPTD alleviates key features of cancer cachexia (right) and may contribute to improving patients’ quality of life (QOL) (bottom).
