High concentration of extracellular nucleotides suppresses cell growth via delayed cell cycle progression in cancer and noncancer cell lines. Heliyon 2021; 7:e08318. [PMID: 34816032 PMCID: PMC8593434 DOI: 10.1016/j.heliyon.2021.e08318] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/28/2021] [Revised: 08/28/2021] [Accepted: 10/29/2021] [Indexed: 02/08/2023] Open
Abstract
Tumor necrosis frequently occurs in malignant tumors, showing rapid growth and invasion. This phenomenon is generally regarded as simple ischemic necrosis due to insufficient tumor vessels and blood supply. However, the necrotic tissue contains high amount of nuclear substances, DNA, and nucleoproteins that may affect the surrounding tumor cells by promoting or suppressing the tumor cell growth in vivo. This study focused on the effects of an externally administered water-soluble nuclear crude extract (SNE) containing nuclear protein and oligonucleotides on several human cancer and noncancer cell lines. The results demonstrated that the SNE suppressed cell growth in cancer and noncancer cells in vitro. Through the flow cytometry analysis of the nuclear DNA content, it was observed that the SNE increased and decreased cell proportion in the S and G2/M phases, respectively, thereby suggesting that the cell growth inhibition was due to cell cycle delay, and not due to apoptosis. These studies suggest that the high-concentration of extracellular nucleotides generated as a result of tumor necrosis and/or released from infiltrated neutrophils could suppress the growth of surrounding cancer and intrinsic cells, which provides us some insights into an alternative anticancer strategy for patients with highly malignant necrotic tumor.

Behavioral and omics analyses study on potential involvement of dipeptide balenine through supplementation in diet of senescence-accelerated mouse prone 8. GENOMICS DATA 2016; 10:38-50. [PMID: 27672559 PMCID: PMC5030327 DOI: 10.1016/j.gdata.2016.09.004] [Citation(s) in RCA: 9] [Impact Index Per Article: 1.1] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 07/22/2016] [Revised: 09/02/2016] [Accepted: 09/07/2016] [Indexed: 01/02/2023]
Abstract
This study investigates effects of dipeptide balenine, as a major component of whale meat extract (hereafter, WME), supplementation on senescence-accelerated mouse prone 8 (SAMP8), an Alzheimer's disease (AD) model at level of learning and memory formation and brain expression profiles genome-wide in brain. Mice fed experimental balenine (+ WME) supplemented diet for 26 weeks were subjected to four behavioral tests – open field, Y-maze, novel object recognition, and water-filled multiple T-maze – to examine effects on learning and memory. Brain transcriptome of SAMP8 mice-fed the WME diet over control low-safflower oil (LSO) diet-fed mice was delineated on a 4 × 44 K mouse whole genome DNA microarray chip. Results revealed the WME diet not only induced improvements in the learning and memory formation but also positively modulated changes in the brain of the SAMP8 mouse; the gene inventories are publically available for analysis by the scientific community. Interestingly, the SAMP8 mouse model presented many genetic characteristics of AD, and numerous novel molecules (Slc2a5, Treh, Fbp1, Aldob, Ppp1r1a, DNase1, Agxt2l1, Cyp2e1, Acsm1, Acsm2, and Pah) were revealed over the SAMR1 (senescence-accelerated mouse resistant 1) mouse, to be oppositely regulated/recovered under the balenine (+ WME) supplemented diet regime by DNA microarray and bioinformatics analyses. Our present study demonstrates an experimental strategy to understand the effects of dipeptide balenine, prominetly contained in meat diet, on SAMP8, providing new insight into whole brain transcriptome changes genome-wide. The gene expression data has been deposited into the Gene Expression Omnibus (GEO): GSE76459. The data will be a valuable resource in examining the effects of natural products, and which could also serve as a human model for further functional analysis and investigation.

A nucleoprotein-enriched diet suppresses dopaminergic neuronal cell loss and motor deficit in mice with MPTP-induced Parkinson's disease. J Mol Neurosci 2014; 55:803-11.

Abstract
Parkinson's disease (PD) is an obstinate progressive neurodegenerative disease and characterized by locomotor impairment and dopaminergic neuronal degeneration in the substantia nigra pars compacta (SNc). We examined in here the dietary effect of nucleoprotein (NP) extracted from salmon soft roe on 1-methyl-4-phenyl-1,2,3,6-tetrahydropyridine (MPTP)-injected PD-like mice model to prevent the symptom as an alternative medicine. Male C57/BL6 mice were given either an artificially modified NP-free diet (NF) or NF supplied with 1.2% NP for 1 week. Then, mice were injected intraperitoneally four times with 20 mg/kg MPTP. Seven days later, locomotor activity was examined, and the brains were immunostained with tyrosine hydroxylase (TH) and Iba1 antibodies. Moreover, in situ detection of superoxide anion (O2(-)) and gene expression of mitochondrial electron transfer chain gene, Cox8b was evaluated in midbrains. NP-fed animals showed significantly reduced locomotor impairment and an increased number of TH-positive cells in the SNc compared with NF animals. The NP-fed animals also showed reduced lower levels of O2(-) and up-regulation of Cox8b levels and Iba1 immunoreactivity, suggesting that inflammation and oxidative stress were suppressed and mitochondrial impairment was relieved in these animals. Supplementation of the diet with NP may serve as a useful preventive measure to slow the onset of PD.

Abstract
We investigated the preventive effects of nucleoprotein on capillary regression and mitochondrial dysfunction induced by unloading in the soleus muscle of rats. Nucleoprotein is a supplement made from soft roe of salmon, and its major components are nucleotides and protamine. Adult male Sprague-Dawley rats were divided randomly into control, hindlimb unloading (HU), and hindlimb unloading plus nucleoprotein administration (HU+ NP) groups. Hindlimb unloading was carried out for 2 weeks in the rats belonging to the HU and the HU+ NP groups. The rats of the HU+ NP group were administered nucleoprotein (500 mg/kg) using a feeding needle twice a day for 2 weeks. Hindlimb unloading resulted in capillary regression, decreased succinate dehydrogenase activity of the muscle fiber, and decreased PGC-1α expression in the soleus muscle. These effects were prevented by administration of nucleoprotein. Nucleoprotein appears to prevent capillary regression and mitochondrial dysfunction caused by unloading of the skeletal muscle. Therefore, nucleoprotein supplementation may be an effective therapy for maintaining capillary network and mitochondrial metabolism of the muscle fiber during an unloading period.
