Abstract
Neuroblastoma (NB) is a common malignant and solid pediatric tumor with unfavorable prognosis. Although studies have shown the anti-tumor efficacy of lentinan (LNT), molecular mechanism that contribute to the anti-tumor effect on NB remains unclear. The aim of this study is to unmask the anti-tumor role of LNT in NB and the specific molecular mechanism. At first, the in vivo experiments were conducted and the results indicated that LNT could suppress tumor growth in NB. Subsequent cellular functional assays unveiled that LNT treatment could efficiently decrease NB cell viability, induce cell cycle stagnation at G0/G1 phase, increase the apoptosis rate, and weaken the migrating and invasive abilities. Furthermore, LNT resulted in a significant downregulation of FOS expression. FOS overexpression recovered the growth, migration and invasion of NB cells suppressed by LNT treatment. Mechanism investigations revealed that FOS interacted with JUND to transcriptionally activate VRK1. Moreover, VRK1 downregulated p53 protein via inducing the phosphorylation of p53 at site 291-393. In summary, this study reveals a novel molecular pathway by which LNT exerts tumor-suppressing functions in NB.
期刊介绍:
Cell Death Discovery is a multidisciplinary, international, online-only, open access journal, dedicated to publishing research at the intersection of medicine with biochemistry, pharmacology, immunology, cell biology and cell death, provided it is scientifically sound. The unrestricted access to research findings in Cell Death Discovery will foster a dynamic and highly productive dialogue between basic scientists and clinicians, as well as researchers in industry with a focus on cancer, neurobiology and inflammation research. As an official journal of the Cell Death Differentiation Association (ADMC), Cell Death Discovery will build upon the success of Cell Death & Differentiation and Cell Death & Disease in publishing important peer-reviewed original research, timely reviews and editorial commentary.
Cell Death Discovery is committed to increasing the reproducibility of research. To this end, in conjunction with its sister journals Cell Death & Differentiation and Cell Death & Disease, Cell Death Discovery provides a unique forum for scientists as well as clinicians and members of the pharmaceutical and biotechnical industry. It is committed to the rapid publication of high quality original papers that relate to these subjects, together with topical, usually solicited, reviews, editorial correspondence and occasional commentaries on controversial and scientifically informative issues.
