Abstract
RATIONALE Intracranial ganglioneuroblastoma represents a rare subtype of primitive neuroectodermal tumor. Here, we report a hippocampal ganglioneuroblastoma and a literature review of cerebral anglioneuroblastoma is carried out. PATIENT CONCERNS We report a 16-year-old male patient presenting with absence seizure and high-infiltration hippocampal ganglioneuroblastoma. INTERVENTIONS Magnetic resonance imaging (MRI) indicates a space-occupying lesion with a well-defined margin in the right temporal lobe and hippocampus. However, hyper-signal on flair and diffusion-weighted imaging (DWI) with a low apparent diffusion coefficient (ADC) value is detected, which prompts high tumoral invasiveness. INTERVENTIONS A total resection of tumor and subsequent chemotherapy combing with radiotherapy is performed. OUTCOMES For a follow-up period of 60 months, no evidence of recurrence and further seizures are detected. LESSONS High-infiltration hippocampal ganglioneuroblastoma is a rare event. MRI examination often showed features of low-grade gliomas, while hyper-signal lesion on DWI with a low ADC value can be detected. Complete resection combined with fractionated radiotherapy and chemotherapy was the optimal treatment for cerebral ganglioneuroblastoma.

Abstract
Arsenic trioxide (As2O3) is an old drug that has recently been reintroduced as a therapeutic agent for acute promyelocytic leukemia (APL). Although As2O3 is also applied to treat other types of cancer in vitro and in vivo, it has been reported that single agent As2O3 has poor efficacy against non-hematologic malignant cancers in clinical trials. Recently, a few reports have indicated that organic arsenic compounds can be a possible alternative for the treatment of As2O3-resistant cancers. In this study, we aimed to investigate whether the organic arsenic compound phenylarsine oxide (PAO) has potent cytotoxic effects against human hepatocellular carcinoma (HCC) HepG2 cells. Our results showed that PAO not only had a potent inhibitory effect on the proliferation of HepG2 cells but also activated apoptosis-related proteins (e.g., caspase-3 and -9 and poly-ADP ribose polymerase) in a dose- and time-dependent manner. Furthermore, intracellular ROS were specifically accumulated in the mitochondria and endoplasmic reticulum (ER) after exposure to PAO, implying that they are the target organelles for PAO-induced cytotoxicity. Additionally, when the cells were pretreated with antioxidant N-acetylcysteine (NAC), apoptosis and ER-stress were attenuated significantly, suggesting that induction of apoptosis and cell death probably occurs through the ROS-mediated mitochondria and ER-stress dependent signaling pathways.

Int J Oncol 2016; 49:2319-2330.

Abstract
This study investigated arsenic trioxide (As2O3), cisplatin (DDP) and etoposide (Vp16) on the anticancer effects and P-glycoprotein (P-gp) expression in neuroblastoma (NB) SK-N-SH cells. The potential influence of As2O3, DDP and Vp16 currently included in NB routine treatment protocols on cytotoxicity in SK-N-SH cells was measured by flow cytometry and drug half-maximal inhibitory concentration (IC50) was established. Moreover, chemotherapeutic agent-mediated changes of cellular expression levels of resistant-related P-gp, was monitored using western blotting. The data showed that As2O3, DDP and Vp16 significantly inhibited the growth and survival of the SK-N-SH cells at different concentration. Notably, the levels of apoptosis were upregulated in SK-N-SH cells with an acceleration of the exposure time and the concentration of As2O3, DDP and Vp16. As2O3, DDP and Vp16 were observed with their IC50 values on SK-N-SH cells being 3 µM, 8 and 100 µg/ml, respectively. Flow cytometry analysis showed that As2O3 at low concentrations in SK-N-SH cells led to enhanced accumulation of cell populations in G2/M phase with increasing the exposure time, and increased levels of apoptosis. In contrast, we observed that SK-N-SH cell populations arrested in S phase by DDP and Vp16. In vitro examination revealed that following pretreatment of SK-N-SH cells with As2O3, the expression of P-gp was not increased. The expression of P-gp downregulation were noted following the group treated by As2O3 at 2 and 3 µM. Exposed to As2O3 at 3 µM for 72 h, SK-N-SH cells exhibited lower expression of P-gp than 2 µM As2O3 for 72 h. In contrast, the expression of P-gp was upregulated by DDP and VP16. In summary, SK-N-SH cells were responsive to chemotherapeutic agent-induced apoptosis in a dose-dependent and time-dependent manner. In particular, ours findings showed that low dose of As2O3 markedly reduced the P-gp expression and increased apoptotic cell death in human NB cell line.

Abstract
Arsenic trioxide (As(2)O(3)) induces both the differentiation and apoptosis of acute promyelocytic leukemia cells in a concentration dependent manner. We assessed the effects of As(2)O(3) in CADO-ES Ewing's sarcoma (ES), JK-GMS peripheral primitive neuroectodermal tumor (PNET), and SH-SY5Y neuroblastoma cells, as they share common histogenetic backgrounds. As(2)O(3) at low concentrations (0.1-1 microM) induced SH-SY5Y differentiation, and whereas PNET cells acquired a slightly differentiated phenotype, change was minimal in ES cells. Extracellular signal-regulated kinase 2 (ERK2) was activated at low As(2)O(3) concentrations, and PD98059, an inhibitor of MEK-1, blocked SH-SY5Y cell differentiation by As(2)O(3). High concentrations (2-10 microM) of As(2)O(3) induced the apoptosis in all three cell lines, and this was accompanied by the activation of c-jun N-terminal kinase. The generation of H(2)O(2) and activation of caspase 3 were identified as critical components of As(2)O(3)-induced apoptosis in all of the above cell lines. Fibroblast growth factor 2 enhanced As(2)O(3)-induced apoptosis in JK-GMS cells. The overall effects of As(2)O(3) strongly suggest that it has therapeutic potential for the treatment of ES/PNET.
