Abstract
The overall survival, progress free survival, and life quality of cancer patients have improved due to the advance in minimally invasive surgery, precision radiotherapy, and various combined chemotherapy in the last decade. Furthermore, the discovery of new types of therapeutics, such as immune checkpoint inhibitors and immune cell therapies have facilitated both patients and doctors to fight with cancers. Moreover, in the context of the development in biocompatible and cell type targeting nano-carriers as well as nucleic acid-based drugs for initiating and enhancing the anti-tumor response have come to the age. The treatment paradigms utilization of nucleic acids, including short interfering RNA (siRNA), antisense oligonucleotides (ASO), and messenger RNA (mRNA), can target specific protein expression to achieve the therapeutic effects. Over ten nucleic acid therapeutics have been approved by the FDA and EMA in rare diseases and genetic diseases as well as dozens of registered clinical trails for varies cancers. Though generally less dangerous of pediatric cancers than adult cancers was observed during the past decades, yet pediatric cancers accounted for a significant proportion of child deaths which hurt those family very deeply. Therefore, it is necessary to pay more attention for improving the treatment of pediatric cancer and discovering new nucleic acid therapeutics which may help to improve the therapeutic effect and prognoses in turns to ameliorate the survival period and quality of life for children patient. In this review, we focus on the nucleic acid therapy in pediatric cancers.

Abstract
Diffuse intrinsic pontine glioma (DIPG) is a rare and fatal pediatric brain tumor. Mutation of p53-induced protein phosphatase 1 (PPM1D) in DIPG cells promotes tumor cell proliferation, and inhibition of PPM1D expression in DIPG cells with PPM1D mutation effectively reduces the proliferation activity of tumor cells. Panobinostat effectively kills DIPG tumor cells, but its systemic toxicity and low blood-brain barrier (BBB) permeability limits its application. In this paper, a nano drug delivery system based on functionalized macrophage exosomes with panobinostat and PPM1D-siRNA for targeted therapy of DIPG with PPM1D mutation is prepared. The nano drug delivery system has higher drug delivery efficiency and better therapeutic effect than free drugs. In vivo and in vitro experimental results show that the nano drug delivery system can deliver panobinostat and siRNA across the BBB and achieve a targeted killing effect of DIPG tumor cells, resulting in the prolonged survival of orthotopic DIPG mice. This study provides new ideas for the delivery of small molecule drugs and gene drugs for DIPG therapy.

Abstract
Next-generation sequencing of pediatric gliomas has revealed the importance of molecular genetic characterization in understanding the biology underlying these tumors and a breadth of potential therapeutic targets. Promising targeted therapies include mTOR inhibitors for subependymal giant cell astrocytomas in tuberous sclerosis, BRAF and MEK inhibitors mainly for low-grade gliomas, and MEK inhibitors for NF1-deficient BRAF:KIAA fusion tumors. Challenges in developing targeted molecular therapies include significant intratumoral and intertumoral heterogeneity, highly varied mechanisms of treatment resistance and immune escape, adequacy of tumor penetrance, and sensitivity of brain to treatment-related toxicities.

Inhibition of mutant PPM1D enhances DNA damage response and growth suppressive effects of ionizing radiation in diffuse intrinsic pontine glioma. Neuro Oncol 2020; 21:786-799.

Abstract
BACKGROUND Children with diffuse intrinsic pontine glioma (DIPG) succumb to disease within 2 years of diagnosis despite treatment with ionizing radiation (IR) and/or chemotherapy. Our aim was to determine the role of protein phosphatase, magnesium-dependent 1, delta (PPM1D) mutation, present in up to 25% of cases, in DIPG pathogenesis and treatment. METHODS Using genetic and pharmacologic approaches, we assayed effects of PPM1D mutation on DIPG growth and murine survival. We assayed effects of targeting mutated PPM1D alone or with IR on signaling, cell cycle, proliferation, and apoptosis in patient-derived DIPG cells in vitro, in organotypic brain slices, and in vivo. RESULTS PPM1D-mutated DIPG cell lines exhibited increased proliferation in vitro and in vivo, conferring reduced survival in orthotopically xenografted mice, through stabilization of truncated PPM1D protein and inactivation of DNA damage response (DDR) effectors p53 and H2A.X. PPM1D knockdown or treatment with PPM1D inhibitors suppressed growth of PPM1D-mutated DIPGs in vitro. Orthotopic xenografting of PPM1D short hairpin RNA-transduced or PPM1D inhibitor-treated, PPM1D-mutated DIPG cells into immunodeficient mice resulted in reduced tumor proliferation, increased apoptosis, and extended mouse survival. PPM1D inhibition had similar effects to IR alone on DIPG growth inhibition and augmented the anti-proliferative and pro-apoptotic effects of IR in PPM1D-mutated DIPG models. CONCLUSIONS PPM1D mutations inactivate DDR and promote DIPG growth. Treatment with PPM1D inhibitors activated DDR pathways and enhanced the anti-proliferative and pro-apoptotic effects of IR in DIPG models. Our results support continued development of PPM1D inhibitors for phase I/II trials in children with DIPG.

Abstract
Central nervous system tumors are the most common solid tumors in pediatrics and represent the largest cause of childhood cancer-related mortality. Improvements have occurred in the management of these patients leading to better survival, but significant morbidity persists. With the era of next generation sequencing, considerable advances have occurred in the understanding of these tumors both biologically and clinically. This information has impacted diagnosis and management. Subgroups have been identified, improving risk stratification. Novel therapeutic approaches, specifically targeting the biology of these tumors, are being investigated to improve overall survival and decrease treatment-related morbidity. The intent of this review is to discuss the genetics of common pediatric brain tumors and the clinical implications. This review will include known genetic disorders associated with central nervous system tumors, neurofibromatosis, tuberous sclerosis, Li-Fraumeni syndrome, Gorlin syndrome, and Turcot syndrome, as well as somatic mutations of glioma, medulloblastoma, and ependymoma.

Abstract
BACKGROUND/AIM Proteomics based on high-resolution mass spectrometry (MS) is the tool of choice for the analysis of protein presence, modifications and interactions, with increasing emphasis on the examination of tumor tissues. Application of MS-based proteomics offers a detailed picture of tumor tissue characteristics, facilitating the appreciation of different tumor entities, whilst providing reliable and fast results for therapeutic marker targeting and prognostic factor assessment. Through use of the high analytical resolution of nano-high-pressure liquid chromatography (nanoHPLC) and the high resolution of an Orbitrap Elite mass spectrometer, the present study aimed to provide knowledge on the proteome of the generally unknown entity of pediatric ependymal tumors. MATERIALS AND METHODS Ten resected specimens of childhood ependymoma were analyzed through a one-dimensional (1D) nanoLC-MS/MS approach. Method optimization steps were undertaken for both the sample preparation/protein extraction procedure and LC parameters, aiming to achieve the highest possible identification rates. RESULTS Following method optimization, each nanoLC-MS/MS run resulted in identification of more than 5,000 proteins and more than 25,000 peptides for every analyzed sample, thus detailing the greater part of the ependymoma proteome. Identified proteins were found to spread throughout all known tumor categories regarding their molecular function and subcellular localization. CONCLUSION Through the proposed nanoLC-MS/MS method herein we report, for the firs time, the ependymoma proteome database. A large number of similarities regarding proteome content are revealed compared to other two pediatric brain tumor entities; astrocytomas and medulloblastomas. Furthermore, through our approach, the majority of currently proposed markers for ependymoma (e.g. nucleolin, nestin, Ki67 and laminin subunit A2) as well as all major key players of the phosphoinositide 3-kinase pathway (seemingly implicated in ependymoma), were definitely detected.
