WDR5-Myc axis promotes the progression of glioblastoma and neuroblastoma by transcriptional activating CARM1.

In this study, we found that WDR5 promoted the proliferation and self-renewal of glioblastoma and neuroblastoma cells. The data from databases and Western blot assay showed that CARM1 is a downstream gene of WDR5-Myc axis. In addition, we observed that WDR5 promoted the binding of Myc to CARM1 promoter by interacting with Myc and inducing histone 3 lysine 4 trimethylation (H3K4me3). Dual luciferase reporter system indicated that Myc binds to the upstream region (-520 to -515) before transcription start site (TSS) of CARM1 promoter. These findings suggest a novel regulatory model for the proliferation and tumorigenesis of glioblastoma and neuroblastoma by WDR5-Myc axis. PMID: 31948749 [PubMed - as supplied by publisher]

Pheochromocytoma (PCC) and paraganglioma (PGL) are rare neuroendocrine tumors associated with high cardiovascular morbidity and variable risk of malignancy. The current therapy of choice is surgical resection. Nevertheless, PCCs/PGLs are associated with a lifelong risk of tumor persistence or recurrence. A high rate of germline or somatic mutations in numerous genes has been found in these tumors. For some, the tumorigenic processes are initiated during embryogenesis. Such tumors carry gene mutations leading to pseudohypoxic phenotypes and show more immature characteristics than other chromaffin cell tumors; they are also ...

ierkens Neuroblastoma (NBL) is the most common extracranial solid tumor in childhood. Despite intense treatment, children with this high-risk disease have a poor prognosis. Immunotherapy showed a significant improvement in event-free survival in high-risk NBL patients receiving chimeric anti-GD2 in combination with cytokines and isotretinoin after myeloablative consolidation therapy. However, response to immunotherapy varies widely, and often therapy is stopped due to severe toxicities. Objective markers that help to predict which patients will respond or develop toxicity to a certain treatment are lacking. Immunothera...

In this study we tried to explore Diazepam as a repurposed drug and tested it in Neuroblastoma (Neuro 2a) cells. Diazepam loaded Poly Lactic Acid Nanoparticles were developed (D-PLA-NPs) using nanoprecipitation method. Entrapment efficiency was found to be ± 99.7% and drug loading was ± 12.88%. The particle size developed was 188.8 nm and zeta potential was −25.6 millivolt. Dissolution profiles were studied in PBS (pH 7.4) or simulated media, almost 50% release was observed within 6 h. In vitro, cytotoxicity was analyzed using MTT assay where dose-dependent cytotoxicity was observed for developed D-PLA-NPs.

Childhood cancer survivors (CCSs) from high-grade malignancies, such as high-risk neuroblastoma, have been increased, and second malignant neoplasm, becomes a serious problem for CCSs. However, detailed reports about rare types of second cancer such as gastric cancer remain limited. We herein reported a female patient who developed diffuse type gastric carcinoma after 21 years from completion of treatment to high-risk neuroblastoma. We reviewed the previous cohort studies for second gastrointestinal cancer in CCSs and the case reports with second gastric carcinoma for CCSs. We presumed second gastric cancer was refractory ...

In this study, two novel benzimidazolium salts consisting propane sulfonate order were integrated in high yields as N-heterocyclic carbene (NHC) precursors.The silver-NHC buildings were set up by responding 1-(2,2-dimethoxyethyl)- 3-(propyl-3-sulfonate)benzimidazolium and 1-(2,2-diethoxyethyl)- 3-(propyl-3-sulfonate)benzimidazolium with silver oxide on average state. Gold-NHC edifices were acquired by means of transmetallation of their silver precursors with [AuCl{S(CH3)2}]. The structures of all mixes were completely portrayed by spectroscopic techniques (1H-NMR, 13C{1H} NMR , IR and elemental and further analyzed by DFT/...

In this study, polydimethylsiloxane-based microfluidic devices were designed, fabricated, and characterized to produce silk particles through self-association of silk when exposed to PVA. Three main variables resulted in differences in particle size and size distribution, or polydispersity index (PDI). Utilizing a co-flow microfluidic device decreased the PDI of the silk particles as compared to an emulsion-based method (0.13 versus 0.65, respectively). With a flow-focusing microfluidics device, lowering the silk flow rate from 0.80 to 0.06 mL/h resulted in a decrease in the median particle size from 6.8 to 3.0 μm a...
