Figure Lengend Snippet: Xenograft mouse model of HCC1954 cells showing the efficacy of FTY720 with or without trastuzumab. ( a ) Mice bearing HCC1954 xenografts were randomized into four treatment groups (n = 9 for each group) when tumor size reached 150–200 mm 3 . Mice were treated with PBS, trastuzumab, FTY720, or FTY720 plus trastuzumab. Xenografts were harvested 24 h after the last treatment. Each plot indicates the mean increase in tumor volume from the first day of treatment, whereas error bars indicate the standard error of the mean. Differences between the four groups were analyzed using ANOVA with mixed-effect model. Differences in control versus FTY720 and control versus FTY720 plus trastuzumab were statistically significant. P value: * P < 0.05 and ** P < 0.01. ( b ) Tumor tissue sections were evaluated using TUNEL assays (green) and also counterstained with Hoechst 33,342 dye (blue, indicating nuclei). They were then examined using fluorescence microscopy. The top three tissue sections with the most abundant green signals in each group were presented. ( c ) Using the same tissue sections, cell membranes were outlined using HER2-antibody conjugating secondary antibody (red) and then examined using fluorescence microscopy. Bar, 100 μm. F plus T: FTY720 plus trastuzumab.

Article Title: Synthesis and evaluation of [ 18 F]FBNAF, a STAT3-targeting probe, for PET imaging of tumor microenvironment

doi: 10.1186/s41181-024-00276-w

Figure Lengend Snippet: Ex vivo autoradiography and immunohistochemical staining in a tumor section removed from a A549 tumor-bearing mouse administered [ 18 F]FBNAF. An autoradiogram was obtained from the tumor excised at 30 min after the injection of [ 18 F]FBNAF. Adjacent sections were used for immunohistochemistry with antibodies against STAT3 and pSTAT3. The results of Hoechst staining are also provided in the supporting information (Fig. S3). The scale bar represents 1000 μm

Article Snippet: Nuclear staining was performed by incubation with Hoechst 33,342 (Nacalai Tesque) for 10 min.
