Additional file 3: of Uniform intratumoral distribution of radioactivity produced using two different radioagents, 64Cu-cyclam-RAFT-c(-RGDfK-)4 and 64Cu-ATSM, improves therapeutic efficacy in a small animal tumor model

Intratumoral distribution of 64Cu-ATSM and microvasculature. An adjacent slice to that presented in Fig. 2b was examined by autoradiography, CD31 immunofluorescence staining, and HE staining. Merged image showing 64Cu-ATSM distribution in green, CD31-stained microvessels in red, and HE stains. High-resolution pictures shown by dotted rectangles clearly depicting the stained microvessels in smaller size in 64Cu-ATSM high- vs. low-accumulated areas. Nuclei were stained with DAPI (blue). Scale bars, 2 mm, 200 μm. (PDF 285 kb

(a) Tumor growth ratios of the same set of treated groups as described in Fig. 3. *, †, ‡P < 0.05 for combination, 64Cu-RaftRGD, and 64Cu-ATSM vs. vehicle control, respectively. Tumor growth ratios (b) and body weight changes (c) of U87MG tumor-bearing mice after co-administration of 64Cu-RaftRGD and 64Cu-ATSM at 111 MBq (55.5 MBq for each agent) and 148 MBq (74 MBq for each agent). Values are the means ± standard deviations (n = 4/group). *, **P < 0.05 and 0.01, respectively for 111 MBq-group vs. 148 MBq group, respectively. It should be noted that although vehicle controls (b, c) were not performed simultaneously along with the 111 MBq and 148 MBq groups, all the three independent experiments (#1 and #2 extracted from Additional file 4 and Additional file 6a, respectively) showed a reproducibly steady increase of the tumor volume in the vehicle-treated mice.

Additional file 5: of Uniform intratumoral distribution of radioactivity produced using two different radioagents, 64Cu-cyclam-RAFT-c(-RGDfK-)4 and 64Cu-ATSM, improves therapeutic efficacy in a small animal tumor model

Tumor growth curves (a) and body weight changes (b) of the same set of experimental groups as described in Fig. 3. Values are the means ± standard deviations (n = 6/group). The final data points shown for each group of mice (b) represent the results obtained at survival endpoint days (represented by a mean value). *, †, ‡P < 0.05 for combination, 64Cu-RaftRGD, and 64Cu-ATSM vs. vehicle control, respectively.
