Figure Legend Snippet: A375 parental and CTL-tolerant persister cell scRNA-seq analysis of (A) signature scores of melanoma cell states observed in patients (Mann-Whitney test), (B) GSEA of the antigen presentation melanoma cell state and (C) expression of selected antigen presentation cell state genes. (D) Proportion of genes in each melanoma cell state which are anastasis-associated genes and (E) A375 cell scRNA-seq expression of selected anastasis-associated genes. (F) ATF3 expression in A375 persisters ± 2 μM IDO1 inhibitor epacadostat or 100 μg/mL tryptophan supplementation added during coculture days 12-15. (G-H) IHC analysis of 4MOSC1 head and neck squamous cell carcinoma syngeneic tumors from mice treated with 10 mg/kg anti-PD-1. (G) Representative IHC images and (H) quantification (n = 4-5 mice, 5 regions were analyzed per tumor). Scale bars, 50 µm. (I-K) Analysis of surgically resected primary human cutaneous melanoma tissue treated with 10 μg/mL anti-PD-1, 10 ng/mL IFNγ, and 10 ng/mL TNF for 6 days in culture. (I) Representative IHC images and (J) quantification (n = 1, five regions were analyzed per tumor slice). Scale bars, 50 µm. (K) Treated primary melanoma cells with elevated caspase 3/7 activity were sorted, replated, and tested for viability 24 hours later by flow cytometry (n = 1). Mean ± SD are plotted and two-tailed unpaired t-tests were performed unless stated otherwise. ns P > 0.05; * P < 0.05; ** P < 0.01; *** P < 0.001; **** P < 0.0001. See also Figure S5 .
Techniques Used: MANN-WHITNEY, Expressing, Activity Assay, Flow Cytometry, Two Tailed Test
Figure Legend Snippet: (A) Representative crystal violet staining and (B) microscopy depicting A375-A cells during one month of recombinant IFNγ ± TNF exposure (1 ng/ml each). Scalebars, 100 μm. (C) Western blot of A375 persister cells which survived 15 days of CTL low coculture or recombinant IFNγ ± TNF (1 ng/ml each) exposure. (D) A375 IFNγ-tolerant persister cells derived from 12 days of IFNγ exposure (1 ng/ml) were further treated from days 12-15 with IDO1 inhibitor (+IDO1i, 2 μM epacadostat) or tryptophan supplementation (+Trp, 100 μg/mL) with continued IFNγ exposure (t-tests versus IFNγ-only). (E) Western blot of ATF3 and ATF4 expression in A375 cytokine-persisters. (F) A375 parental cell viability after 6 days of cytokine treatment (t-tests versus untreated cells). (G) A375 cell viability after 15 days of recombinant IFNγ ± TNF exposure to form persister cells (t-tests versus 1 ng/ml IFNγ). (H) Western blot of IDO1 expression in A375 cytokine-persisters. (I) Quantification of A375-A EC formation after one month of IFNγ ± TNF exposure (1 ng/ml each). (J) Viability of A375 IFNγ + TNF-tolerant persister and EC cells regrown without cytokines and then rechallenged with 9 days of IFNγ + TNF exposure (1 ng/ml each) or (K) 6 days of CTL coculture (t-tests versus parental). The three cytokine-resistant ECs isolated from IFNγ ± TNF exposure of bulk A375 cells shown in J are the same ECs which are cross-resistant to CTL low exposure shown in K . N = 3, mean ± SD are plotted, and two-tailed unpaired t-tests were performed unless stated otherwise. * P < 0.05; ** P < 0.01; *** P < 0.001; **** P < 0.0001. See also Figure S9 .
