doi: 10.3389/fnmol.2019.00007

Figure Lengend Snippet: Percentage changes in Neuro2a- and C6-cell viability after 12 h and 24 h treatment with different doses of NA and H 2 O 2 are shown. Viability of both Neuro2a (A) and C6 (B) was least affected (<15% of control) by treatment with up to 10 μM of NA, whereas H 2 O 2 affected the cell viability in even much lesser concentration. * p < 0.05, ** p < 0.01, *** p < 0.001 as compared to control. Abbreviations are as in the text. (C) Representative microscopic fields of images of Neuro2a and C6 cells with or without treatment with NA (10 μM), H 2 O 2 or their combination are shown. Both Neuro2a as well as C6 cells showed less adherence to the petri-dish. Those remained adhered, showed membrane granulation and more circular (marked by arrows as representative), which are signs of cellular stress/damage or approaching death upon H 2 O 2 treatment for 24 h. Cells treated with H 2 O 2 in presence of NA showed reduced -detachment, -granulation and -circular shaped in addition to lesser death. Scale bar 100 μm.

Figure Lengend Snippet: Changes in LP (mean ± SEM nmol of MDA) and intracellular ROS levels (as expressed by DCF fluorescence) in Neuro2a and C6 cells under control and various treatment conditions are shown as box-plots. Confluent cell culture containing about 2 × 10 7 cells grown in 100 mm petri dishes were treated with Vit E, NA (10 μM), PRZ, H 2 O 2 alone or in combinations (as shown in respective bars). Vit E (except in Neuro2a), NA and PRZ alone were by and large ineffective in modulating the LP. H 2 O 2 induced increased LP was reduced by NA and Vit E in both Neuro2a (A) and C6 (B) . The protective effect of NA on H 2 O 2 induced LP was lost in presence of PRZ. As shown in (C,D) in both Neuro2a and C6 respectively, ROS was increased by H 2 O 2 , while it was decreased by NA and Vit E. The H 2 O 2 induced effects were prevented by NA and Vit E. As the NA induced effects were not prevented by AR antagonists, PRZ or PRP, it suggested that the effects were not mediated through (ARs). *** p < 0.001 as compared to untreated control and $$ p < 0.01 in comparison with H 2 O 2 treated cells.

Figure Lengend Snippet: NA mediated modulation of intracellular ROS levels in presence of iron in Neuro2a (A) and C6 (B) is shown. 2 × 10 5 cells per well were seeded in 96 well plates and incubated for 12 h in serum free medium lacking iron or in medium containing 10 μM FeSO 4 as source of iron (Fe 2+ ). Cells in both the media were treated with H 2 O 2 alone or in presence of NA or DFX for 2 h. At the end the cells were incubated with medium containing 25 μM DCFDA for 30 min followed by PBS washing and DCF fluorescence estimation. In the presence of Fe 2+ , H 2 O 2 enhanced ROS generation in both the cells, Neuro2a (A) and C6 (B) , which were prevented by DFX and NA. ** p < 0.01, *** p < 0.001 as compared with control.

Figure Lengend Snippet: Protective role of NA (10 μM) on H 2 O 2 -induced ROS generation and cell death in Neuro2a (upper panels, A–D ) and C6 (lower panels, E–H ) is shown. Representative photomicrographs of intracellular DCF fluorescence indicative of ROS levels in Neuro2a (A) and C6 (E) are shown. Cells treated with H 2 O 2 alone showed significantly higher fluorescence per cell, while NA treated cells showed significantly reduced fluorescence per cell upon H 2 O 2 treatment. Corresponding histograms of relative fluorescence intensities per cell (mean of 500–600 cells per treatment) from five sets of experiments of Neuro2a (B) and C6 (F) are shown. In separate sets of experiments, the cells were treated for 24 h and percent dead cells were quantified using trypan blue assay. H 2 O 2 significantly increased cell death, which was protected in presence of NA for Neuro2a (C) and C6 (G) . Also, using DAPI (stains all live and dead cells) and PI (stains only dead cells) the proportion of dead cells were quantified in coverslip-grown cells treated with NA, H 2 O 2 or both together. Significantly more number of nuclei were PI (red) stained by treatment of H 2 O 2 alone as compared to NA alone and NA+H 2 O 2 . Representative photomicrographs (20X) of DAPI and PI stained Neuro2a (D) and C6 (H) are shown. PI stained cell shown in red are dead while DAPI stained all nuclei irrespective of live or dead are shown in blue; PI stained cells are seen more in H 2 O 2 treated groups. All readings were taken in duplicate and three ( N = 3) such sets of experiments were conducted. *** p < 0.001 as compared to untreated cells, while $$ p < 0.01 as compared to H 2 O 2 treated cells.

Article Title: Multi-Targeted Neutron Capture Therapy Combined with an 18 kDa Translocator Protein-Targeted Boron Compound Is an Effective Strategy in a Rat Brain Tumor Model

doi: 10.3390/cancers15041034

Figure Lengend Snippet: ( A ) This figure shows the cellular uptakes of boron using three boron-10 compounds. DPA-BSTPG, BPA, or BSH for F98 glioma cell lines were 60.3 ± 3.8, 11.9 ± 0.5, or 3.0 ± 0.2 μg boron B/10 9 cells, respectively. In C6 rat glioma cells, 26.0 ± 2.4, 6.5 ± 0.2, or 3.2 ± 0.1 μg B/10 9 cells, respectively. In 9L rat glioma cells, 24.0 ± 4.0, 24.3 ± 1.7, or 5.3 ± 0.4 μg B/10 9 cells, respectively. In F98 and C6 rat glioma, DPA-BSTPG was the highest boron uptake, with statistically significant uptake compared to BPA (F98; p < 0.0001, C6; p = 0.0003, respectively) or BSH (F98; p < 0.0001, C6; p = 0.0002, respectively), while BPA was the highest boron uptake in 9L rat glioma (vs. DPA-BSTPG; p = 0.93) and DPA-BSTPG had statistically significant uptake compared to BSH ( p = 0.0027). ( B ) The TSPO expression of each F98 brain tumor was evaluated. The ratio of TSPO to β-actin between F98 rat brain tumor to normal brain in an F98 rat glioma model was calculated using the 2 -ΔΔ CT method with real-time PCR in F98 rat glioma models. The ratios were 13.95, 23.07, and 11.09, respectively, indicating that the TSPO expression was 16-hold higher on average in the F98 brain tumor than in the normal brain.

Figure Lengend Snippet: The absorbed doses required to obtain at survival fraction (SF) = 0.1 were 6.45 Gy in the LQ model, 2.63 Gy in the mixed neutron beam alone, 1.39 Gy in the BPA group, and 0.88 Gy in the DPA-BSTPG group, respectively. In the Neutron only curve at SF = 0.1, the dose exerted on γ-rays component mixed with neutron irradiation was excluded from 6.45 Gy, and the relative biological effectiveness (RBE) to the mixed neutron beam (RBE-beam) was calculated since there was no dose contributed by boron-10. As a result, the RBE-beam was estimated as 3.00. The CBE for F98 rat glioma cell of BPA, BSH, and DPA-BSTPG were 3.80, 2.41 and 8.43 respectively.

Figure Lengend Snippet: The survival times in days after implantation of 10 3 F98 rat glioma cells have been plotted. Five groups were prepared: Untreated, Neutron only, DPA-BSTPG-BNCT, BPA-BNCT, and Combination BNCT. There were statistically significant differences between three BNCT groups and the Untreated group (vs. DPA-BSTPG-BNCT, p = 0.0008; vs. BPA-BNCT, p = 0.0008; vs. Combination BNCT, p = 0.0008, respectively, log-rank test), with all BNCT groups showing prolonged survival times. There was a statistically significant difference observed between BPA-BNCT and DPA-BSTPG-BNCT ( p = 0.0187, log-rank test). On the other hand, a statistically significant prolongation of survival times was observed in Combination BNCT compared to BPA-BNCT ( p = 0.0121, log-rank test). In this study, Combination BNCT obtained the longest survival among all groups.
