Figure Legend Snippet: Gene-expression data revealed metabolic differences of primary ovarian tumors and omental tumors from patients with stage III OC (n = 30). (A) Distinct clustering in t-SNE plot of metabolic gene data from matched primary ovarian tumors (blue) and omental metastases (red). (B) Volcano plot of gene-expression changes for paired ovarian and omental tumors highlighted genes significantly upregulated in omental tumors (red) and ovarian tumors (blue). (C) Pathway analysis of the significantly altered genes. (D) Volcano plot of metabolite abundances determined by liquid chromatography-mass spectrometry (LC-MS) metabolomic analysis of matched ovarian and omental pairs (n = 8). (E) Pathway enrichment analysis of metabolomics data; symbol size indicates pathway impact and color indicates p value. (F) Changes in PPP metabolite abundances are plotted as outlined circles. Blue circles indicate the normalized primary tumor measurements for all tumor pairs (n = 8). (G) G6PD expression in ovarian and omental metastases (n = 8) was quantified using qPCR. (H) G6PD activity of tumor pairs (n = 3) was measured via enzymatic assay. (I) Tumor lysates (n = 3 pairs) were incubated with 25 μM DCFH-DA, and fluorescence was measured at 30 minutes. All summary bar graphs represent mean ± SD. Statistical significances are noted as *p < 0.05, **p < 0.01 by two-tailed Student’s t tests.
Techniques Used: Expressing, Liquid Chromatography, Mass Spectrometry, Liquid Chromatography with Mass Spectroscopy, Activity Assay, Enzymatic Assay, Incubation, Fluorescence, Two Tailed Test
Figure Legend Snippet: (A) HEYA8, SKOV3, and IGROV1 tumors were imaged by IVIS (n = 2 per cell line). (B) Intravital imaging showed metastatic seeding and growth in the omentum at 6 and 42 h. (C) Immunoblotting for G6PD expression in murine omental tumor samples. (D) Enzymatic measurement of G6PD activity in primary tumors and omental metastases (n = 4). (E) Tumor lysates were incubated with 25 μM DCFH-DA, and fluorescence was quantified (n = 3). The sample size (n) represents the number of technical replicates. All summary bar graphs represent mean ± SD. Statistical significances are noted as *p < 0.05, **p < 0.01 by two-tailed Student’s t tests.
Techniques Used: Imaging, Western Blot, Expressing, Activity Assay, Incubation, Fluorescence, Two Tailed Test
Figure Legend Snippet: (A) OC cell lines grown in OCM were incubated with DCFH-DA, and fluorescence was quantified (n = 6). (B) SKOV3 OC cells were transfected with constructs for the intracellular H 2 O 2 sensor, HyPer (n = 3). Ratiometric fluorescence was measured at 0, 12, 24, and 48 h. (C) HyPer signal quantification of OC organoids cultured in omental conditioned organoid media (n = 3). Scale bars, 100 μM. (D and E) G6PD expression via immunoblotting (D) and G6PD activity measured via enzymatic assay (E) in OCM-cultured cells (n = 3). (F) NADPH/NADP+ ratios of OC cells invading an ex vivo omental culture measured by iNAP, a NADPH/NADP+ ratiometric biosensor (n = 3). Scale bars, 100 μM. (G) Immunoblotting for G6PD in OC cell lines after lentiviral shRNA knockdown. (H) Quantification of oxidative stress measured via DCFH-DA signal in WT and G6PD shRNA-expressing OC cells cultured in OCM (n = 3). (I) Quantification of cytotoxicity measured via Sytox staining of OCM and polydatin-treated OC cells (n = 3). The sample size (n) represents the number of technical replicates. All summary bar graphs represent mean ± SD. Statistical significances are noted as *p < 0.05, **p < 0.01 by two-tailed Student’s t tests.
