Figure Lengend Snippet: Figure 2. The GLUT3 protein is upregulated in hypoxic immortalized prostate epithelial cells. (Upper and Middle panels) RWPE1 cells were cultured in either normoxic or under chronic hypoxic (1% O2) conditions for 48 h and then processed for immunofluorescence microscopy. Cells were stained for either CA9, GLUT1, or GLUT3 (green, Upper and Middle panels). DNA, blue. Scale, 25 µm. (Lower panels) Comparison of flow cytometry profiles of CA9, GLUT1, or GLUT3 in cells cultured in normoxia (red) versus hypoxia (yellow). Cells stained with only secondary antibody is shown (dark red). The fold increase in level of the indicated proteins is denoted. PE, phycoerythrin.

Figure Lengend Snippet: Figure 3. GLUT3 co-localizes with pimonidazole (Hypoxyprobe) in mouse xenograft tumors formed from prostate epithelial CTN-2-2 cells. Non-tumorigenic immortalized prostate epithelial PrEC-Hahn cells were transformed by transiently inducing chromosomal instability. The resulting tumorigenic line was named CTN-9, which produced malignant solid xenograft tumors in subcutaneously in- jected NSG mice [52]. Cell lines isolated from these tumors were named CTN1-2 and 2-2 lines [52]. (Upper panel) Single tumor section stained for pimonidazole (PIMO) (green) and GLUT3 (red). DNA, blue. Boxed regions are shown at higher magnification in the lower panels. (Lower panels) Higher magnification images from boxed regions 1 or 2 in upper panel. Serial tissue sections were stained for hematoxylin and eosin (H&E), PIMO (green), and GLUT3, GLUT1 or CA9 (red) as indicated. Concentrations of GLUT3 (yellow arrows) and CA9 (white arrows) that juxtapose with PIMO are marked. Dashed white boxes show GLUT3 concentrated at the plasma membrane in tumor cells (insets). Scale, 100 µm.

Figure Lengend Snippet: Figure 5. Measurements of the co-localization of hypoxia markers in xenograft tumors show a high degree of association between pimonidazole and GLUT3. (a) Single section from a CTN2-2 tumor immunostained for pimonidazole (PIMO) (green) and GLUT3 (red). DNA, blue. Scale, 100 µm. (b) To quantify co-localization of hypoxia markers GLUT1, GLUT3, and CA9 with PIMO, binary tracings were placed around the PIMO signal (green lines) defined a threshold of intensity specific to each tumor. Binaries were then dilated >0–15 µm (orange lines) and >15–30 µm (red lines) to capture the adjacent signal of each hypoxia marker. Same image as in (a). (c) Graphs show fold change in mean fluorescence intensities of hypoxia markers GLUT1, GLUT3 and CA9 within three PIMO-positive or adjacent regions captured within the expanded binary masks: 0 µm where the PIMO signal resides, >0–15 µm (orange bars) and >15–30 µm (red bars). Mean fluorescence intensities within these three regions was divided by ‘background’ signal from regions >30 µm from the PIMO signal. A dashed line indicates no change in signal relative to the background. Four optical fields in tissue sections from two different DU145, CTN1-2 and CTN2-2 tumors were analyzed (six different tumors examined in total).

Figure Lengend Snippet: Figure 8. Compared to hypoxia biomarkers GLUT1 and CA9, GLUT3 labels larger areas within PDX tumor sections. (a) Patient-derived xenograft (PDX) from a primary prostate tumor immunostained with the triple anti-CA9, GLUT1, and GLUT3 antibody cocktail. Scale, 100 µm. (b) Same image as in (a) with binary mask to outline regions of the triple stain. (c) Graph shows measurements of total area of each stain within 3 different PDX prostate tumors. Three sequential sections were obtained from each tumor, stained for either CA9/GLUT1, GLUT3, or the triple stain CA9/GLUT1/GLUT3, and imaged. Total area of staining was quantified by masking regions of high intensity staining using Nikon Elements image analysis software. Note, in the metastatic prostate PDX tumor samples, the vast majority of the signal observed in the triple stain is due to the GLUT3 stain. However, in the primary prostate PDX, GLUT3 staining alone is not as effective at revealing putative hypoxic regions compared to the triple stain.

Figure Lengend Snippet: Vemurafenib induces a decrease in transmembrane glucose uptake per cell. A, 3μM Vemurafenib (+) incubation induces a decrease in transport of the non-phosphorylatable glucose analog 3-OMG normalized to cell count in sensitive lines but not B, acquired resistant lines relative to DMSO (−) after 72 hours. C, Vemurafenib treatment does not cause a significant decrease in GLUT1 or GLUT3 proteins levels in sensitive or resistant lines by 72 hours.
