Abstract
Apoptosis plays an essential role in the pathophysiologic processes of rheumatoid arthritis. A molecular probe that allows spatiotemporal observation of apoptosis in vitro, in vivo, and ex vivo concomitantly would be useful to monitoring or predicting pathophysiologic stages. In this study we investigated whether cyclic apoptosis-targeting peptide-1 (CApoPep-1) can be used as an apoptosis imaging probe in inflammatory arthritis. We tested the utility of CApoPep-1 for detecting apoptotic immune cells in vitro and ex vivo using flow cytometry and immunofluorescence. The feasibility of visualizing and quantifying apoptosis using this probe was evaluated in a murine collagen-induced arthritis (CIA) model, especially after treatment. CApoPep-1 peptide may successfully replace Annexin V for in vitro and terminal deoxynucleotidyl transferase dUTP nick end labeling (TUNEL) assay for ex vivo in the measurement of apoptotic cells, thus function as a sensitive probe enough to be used clinically. In vivo imaging in CIA mice revealed that CApoPep-1 had 42.9 times higher fluorescence intensity than Annexin V for apoptosis quantification. Furthermore, it may be used as an imaging probe for early detection of apoptotic response in situ after treatment. The CApoPep-1 signal was mostly co-localized with the TUNEL signal (69.6% of TUNEL+ cells) in defined cell populations in joint tissues of CIA mice. These results demonstrate that CApoPep-1 is sufficiently sensitive to be used as an apoptosis imaging probe for multipurpose applications which could detect the same target across in vitro, in vivo, to ex vivo in inflammatory arthritis.

Abstract
Cell death plays a prominent role in the treatment of cancer, because most anticancer therapies act by the induction of cell death including apoptosis, necrosis, and other pathways of cell death. Imaging cell death helps to identify treatment responders from nonresponders and thus enables patient-tailored therapy, which will increase the likelihood of treatment response and ultimately lead to improved patient survival. By taking advantage of molecular probes that specifically target the biomarkers/biochemical processes of cell death, cell death imaging can be successfully achieved. In recent years, with the increased understanding of the molecular mechanism of cell death, a variety of well-defined biomarkers/biochemical processes of cell death have been identified. By targeting these established cell death biomarkers/biochemical processes, a set of molecular imaging probes have been developed and evaluated for early monitoring treatment response in tumors. In this review, we mainly present the recent advances in identifying useful biomarkers/biochemical processes for both apoptosis and necrosis imaging and in developing molecular imaging probes targeting these biomarkers/biochemical processes, with a focus on their application in early evaluation of tumor response to therapy.

Abstract
Cartilage injury induced by acute excessive contact stress is common and mostly affects young adult. Although early detection of cartilage injury may prevent serious and lifelong arthritic complications, early detection and treatment is not possible due to the lack of a reliable detection method. Since chondrocyte injury and subsequent cell death are the early signs of cartilage injury, it is likely that cartilage cell apoptosis can be used to predict the extent of injury. To test this hypothesis, a near infrared probe was fabricated to have high affinity to apoptotic cells. In vitro tests show that this apoptosis probe has low toxicity, high specificity, and high affinity to apoptotic cells. In addition, there is a positive relationship between apoptotic cell numbers and fluorescence intensities. Using a mouse xiphoid injury model, we found significant accumulation of the apoptosis probes at the injured xiphoid cartilage site. There was also a positive correlation between probe accumulation and the number of apoptotic chondrocytes within the injured xiphoid cartilage, which was confirmed by TUNEL assay. The results support that the apoptosis probes may serve as a powerful tool to monitor the extent of mechanical force-induced cartilage injury in vivo.

Abstract
Assessment of myocardial viability is deemed necessary to aid in clinical decision making whether to recommend revascularization therapy for patients with myocardial infarction (MI). Dianthraquinones such as hypericin (Hyp) selectively accumulate in necrotic myocardium, but were unsuitable for early imaging after administration to assess myocardial viability. Since dianthraquinones can be composed by coupling two molecules of monomeric anthraquinone and the active center can be found by splitting chemical structure, we propose that monomeric anthraquinones may be effective functional groups for necrosis targetability. In this study, eight radioiodinated monomeric anthraquinones were evaluated as novel necrosis avid agents (NAAs) for imaging of necrotic myocardium. All (131)I-anthraquinones showed high affinity to necrotic tissues and (131)I-rhein emerged as the most promising compound. Infarcts were visualized on SPECT/CT images at 6 h after injection of (131)I-rhein, which was earlier than that with (131)I-Hyp. Moreover, (131)I-rhein showed satisfactory heart-to-blood, heart-to-liver and heart-to-lung ratios for obtaining images of good diagnostic quality. (131)I-rhein was a more promising "hot spot imaging" tracer for earlier visualization of necrotic myocardium than (131)I-Hyp, which supported further development of radiopharmaceuticals based on rhein for SPECT/CT ((123)I and (99m)Tc) or PET/CT imaging ((18)F and (124)I) of myocardial necrosis.

Abstract
PURPOSE Sodium [(18)F]fluoride (Na[(18)F]F) positron emission tomography with integrated computed tomography (PET/CT) has not been used for imaging myocardial infarction (MI). Here, we aimed to investigate the Na[(18)F]F PET/CT features of MI in a rat model. PROCEDURES MI was induced by coronary artery ligation in 8-week-old male Spraque-Dawley rats (300 ± 10 g) and confirmed by triphenyl tetrazolium chloride (TTC) staining. Na[(18)F]F PET/CT images were obtained using an animal-dedicated PET/CT scanner (NanoPET/CT, Mediso) in vivo and ex vivo. Uptake of Na[(18)F]F was quantitated using the standardized uptake value (SUV). Myocardial apoptosis was evaluated using histone-1 targeted peptide (ApoPep-1) and terminal deoxynucleotidyl transferase dUTP nick end labeling (TUNEL) staining, while calcium accumulation was investigated using von Kossa's staining. Na[(18)F]F PET/CT was compared with (99m)Tc-methoxyisobutylisonitrile (MIBI) or (99m)Tc-hydroxymethylenediphosphonate (HMDP) single photon emission computed tomography/computed tomography (SPECT/CT) in rats with day 1 MI. RESULTS The rats showed strong Na[(18)F]F uptake both in vivo and ex vivo; the maximal uptake occurred 1 day after MI (SUV ratio of infarct to lung = 4.56 ± 0.74, n = 7, P = 0.0183 vs the control). The Na[(18)F]F uptake area perfectly matched the apoptotic area, determined by ApoPep-1 uptake and TUNEL assay. However, calcification, assessed by von Kossa's staining, was absent in the infarct. Na[(18)F]F PET/CT showed an increased uptake at the perfusion deficit area in [(99m)Tc]MIBI SPECT/CT and an equivalent signal to [(99m)Tc]HMDP SPECT/CT in rats with day 1 MI. CONCLUSIONS Na[(18)F]F PET/CT is a promising hot-spot imaging modality for MI.

Abstract
The therapeutic efficacy of radioiodine (¹³¹I) therapy has been reported to be variable among cancer patients and even between metastatic regions in the same patients. Because the expression level of sodium iodide symporter (NIS) cannot reflect the efficacy of therapy, other strategies are required to predict the precise therapeutic effect of ¹³¹I therapy. In this research, we investigated the correlation between iodine (I) uptake, apoptosis imaging, and therapeutic efficacy. Two HT29 cell lines, cytomegalovirus (CMV)-NIS (or NIS+++) and TERT-NIS (or NIS+), were established by retroviral transfection. I uptake was estimated by I-uptake assay and gamma camera imaging. Apoptosis was evaluated by confocal microscopy and a Maestro fluorescence imaging system (CRi Inc., Woburn, MA) using ApoFlamma (BioACTs, Seoul, Korea), a fluorescent dye-conjugated apoptosis-targeting peptide 1 (ApoPep-1). Therapeutic efficacy was determined by tumor size. The CMV-NIS showed higher I uptake and ApoFlamma signals than TERT-NIS. In xenograft models, CMV-NIS also showed high 99m technetium signals and ApoFlamma signals. Tumor reduction had a stronger correlation with apoptosis imaging signals than with gamma camera imaging signals, which reflect I uptake. Higher NIS-expressing tumors showed increased apoptosis and I uptake, resulting in a significant tumor reduction. Moreover, tumor reduction showed a strong correlation with ApoFlamma imaging compared to I-uptake imaging.

Abstract
Early decision on tumor response after anti-cancer treatment is still an unmet medical need. Here we investigated whether in vivo imaging of apoptosis using linear and cyclic (disulfide-bonded) form of ApoPep-1, a peptide that recognizes histone H1 exposed on apoptotic cells, at an early stage after treatment could predict tumor response to the treatment later. Treatment of stomach tumor cells with cistplatin or cetuximab alone induced apoptosis, while combination of cisplatin plus cetuximab more efficiently induced apoptosis, as detected by binding with linear and cyclic form of ApoPep-1. However, the differences between the single agent and combination treatment were more remarkable as detected with the cyclic form compared to the linear form. In tumor-bearing mice, apoptosis imaging was performed 1 week and 2 weeks after the initiation of treatment, while tumor volumes and weights were measured 3 weeks after the treatment. In vivo fluorescence imaging signals obtained by the uptake of ApoPep-1 to tumor was most remarkable in the group injected with cyclic form of ApoPep-1 at 1 week after combined treatment with cisplatin plus cetuximab. Correlation analysis revealed that imaging signals by cyclic ApoPep-1 at 1 week after treatment with cisplatin plus cetuximab in combination were most closely related with tumor volume changes (r2 = 0.934). These results demonstrate that in vivo apoptosis imaging using Apopep-1, especially cyclic ApoPep-1, is a sensitive and predictive tool for early decision on stomach tumor response after anti-cancer treatment.
