Abstract
Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) is currently the most important emerging pathogen worldwide, but its early transcriptional dynamics and host immune response remain unclear. Herein, the expression profiles of viral interactions with different types of hosts were comprehensively dissected to shed light on the early infection strategy of SARS-CoV-2 and the host immune response against infection. SARS-CoV-2 was found to exhibit a two-stage transcriptional strategy within the first 24 h of infection, comprising a lag phase that ends with the virus being paused and a log phase that starts when the viral load increases rapidly. Interestingly, the host innate immune response was found not to be activated (latent period) until the virus entered the log stage. Noteworthy, when intracellular immunity is suppressed, SARS-CoV-2 shows a correlation with dysregulation of metal ion homeostasis. Herein, the inhibitory activity of copper ions against SARS-CoV-2 was further validated in in vitro experiments. Coronavirus disease 2019-related genes (including CD38, PTX3, and TCN1) were also identified, which may serve as candidate host-restricted factors for interventional therapy. Collectively, these results confirm that the two-stage strategy of SARS-CoV-2 effectively aids its survival in early infection by regulating the host intracellular immunity, highlighting the key role of interferon in viral infection and potential therapeutic candidates for further investigations on antiviral strategies.

Abstract
Amyotrophic lateral sclerosis (ALS) is characterized by progressive degeneration of motor neurons. Astrocytes from diverse ALS models induce motor neuron death in co-culture. Enhancing NAD+ availability, or increasing the expression of the NAD+-dependent deacylases SIRT3 and SIRT6, abrogates their neurotoxicity in cell culture models. To determine the effect of increasing NAD+ availability in ALS mouse models we used two strategies, ablation of a NAD+-consuming enzyme (CD38) and supplementation with a bioavailable NAD+ precursor (nicotinamide riboside, NR). Deletion of CD38 had no effect in the survival of two hSOD1-linked ALS mouse models. On the other hand, NR-supplementation delayed motor neuron degeneration, decreased markers of neuroinflammation in the spinal cord, appeared to modify muscle metabolism and modestly increased the survival of hSOD1G93A mice. In addition, we found altered expression of enzymes involved in NAD+ synthesis (NAMPT and NMNAT2) and decreased SIRT6 expression in the spinal cord of ALS patients, suggesting deficits of this neuroprotective pathway in the human pathology. Our data denotes the therapeutic potential of increasing NAD+ levels in ALS. Moreover, the results indicate that the approach used to enhance NAD+ levels critically defines the biological outcome in ALS models, suggesting that boosting NAD+ levels with the use of bioavailable precursors would be the preferred therapeutic strategy for ALS.

Abstract
Progression through states of pluripotency is required for cells in early mammalian embryos to transition away from heightened self-renewal and toward competency for lineage specification. Here, we use a CRISPR mutagenesis screen in mouse embryonic stem cells (ESCs) to identify unexpected roles for nuclear export and intracellular Ca2+ homeostasis during the exit out of the naive state of pluripotency. Mutation of a plasma membrane Ca2+ pump encoded by Atp2b1 increased intracellular Ca2+ such that it overcame effects of intracellular Ca2+ reduction, which is required for naive exit. Persistent self-renewal of ESCs was supported both in Atp2b1-/-Tcf7l1-/- double-knockout ESCs passaged in defined media alone (no LIF or inhibitors) and in wild-type cells passaged in media containing only calcitonin and a GSK3 inhibitor. These new findings suggest a central role for intracellular Ca2+ in safeguarding naive pluripotency.

Abstract
We reveal by high-throughput screening that activating transcription factor 1 (ATF1) is a novel pluripotent regulator in human embryonic stem cells (hESCs). The knockdown of ATF1 expression significantly up-regulated neuroectoderm (NE) genes but not mesoderm, endoderm, and trophectoderm genes. Of note, down-regulation or knockout of ATF1 with short hairpin RNA (shRNA), small interfering RNA (siRNA), or clustered regularly interspaced short palindromic repeats (CRISPR)/CRISPR-associated protein 9 (Cas9) was sufficient to up-regulate sex-determining region Y-box (SOX)2 and paired box 6 (PAX6) expression under the undifferentiated or differentiated conditions, whereas overexpression of ATF1 suppressed NE differentiation. Endogenous ATF1 was spontaneously down-regulated after d 1-3 of neural induction. By double-knockdown experiments, up-regulation of SOX2 was critical for the increase of PAX6 and SOX1 expression in shRNA targeting Atf1 hESCs. Using the luciferase reporter assay, we identified ATF1 as a negative transcriptional regulator of Sox2 gene expression. A novel function of ATF1 was discovered, and these findings contribute to a broader understanding of the very first steps in regulating NE differentiation in hESCs.-Yang, S.-C., Liu, J.-J., Wang, C.-K., Lin, Y.-T., Tsai, S.-Y., Chen, W.-J., Huang, W.-K., Tu, P.-W.

Abstract
Autism spectrum disorder (ASD) is characterized by early onset of behavioral and cognitive alterations. Low plasma levels of oxytocin (OT) have also been found in ASD patients; recently, a critical role for the enzyme CD38 in the regulation of OT release was demonstrated. CD38 is important in regulating several Ca2+-dependent pathways, but beyond its role in regulating OT secretion, it is not known whether a deficit in CD38 expression leads to functional modifications of the prefrontal cortex (PFC), a structure involved in social behavior. Here, we report that CD38-/- male mice show an abnormal cortex development, an excitation-inhibition balance shifted toward a higher excitation, and impaired synaptic plasticity in the PFC such as those observed in various mouse models of ASD. We also show that a lack of CD38 alters social behavior and emotional responses. Finally, examining neuromodulators known to control behavioral flexibility, we found elevated monoamine levels in the PFC of CD38-/- adult mice. Overall, our study unveiled major changes in PFC physiologic mechanisms and provides new evidence that the CD38-/- mouse could be a relevant model to study pathophysiological brain mechanisms of mental disorders such as ASD.-Martucci, L.

Abstract
INTRODUCTION Human embryonic stem cells (hESCs) have unique biological features and attributes that make them attractive in various areas of biomedical research. With heightened applications, there is an ever increasing need for advancement of proteome analysis. Membrane proteins are one of the most important subset of hESC proteins as they can be used as surface markers. Areas covered: This review discusses commonly used surface markers of hESCs, and provides in-depth analysis of available hESC membrane proteome reports and the existence of these markers in many other cell types, especially cancer cells. Appreciating, existing ambiguity in the definition of a membrane protein, we have attempted a meta analysis of the published membrane protein reports of hESCs by using a combination of protein databases and prediction tools to find the most confident plasma membrane proteins in hESCs. Furthermore, responsiveness of plasma membrane proteins to differentiation has been discussed based on available transcriptome profiling data bank. Expert commentary: Combined transcriptome and membrane proteome analysis highlighted additional proteins that may eventually find utility as new cell surface markers.

Abstract
SIGNIFICANCE Nicotinamide adenine dinucleotide (NAD+) participates in redox reactions and NAD+-dependent signaling processes, which involve the cleavage of NAD+ coupled to posttranslational modifications of proteins or the production of second messengers. Either as a primary cause or as a secondary component of the pathogenic process, mitochondrial dysfunction and oxidative stress are prominent features of several neurodegenerative diseases. Activation of NAD+-dependent signaling pathways has a major effect in the capacity of the cell to modulate mitochondrial function and counteract the deleterious effects of increased oxidative stress. Recent Advances: Progress in the understanding of the biological functions and compartmentalization of NAD+-synthesizing and NAD+-consuming enzymes have led to the emergence of NAD+ metabolism as a major therapeutic target for age-related diseases. CRITICAL ISSUES Three distinct families of enzymes consume NAD+ as substrate: poly(ADP-ribose) polymerases (PARPs), ADP-ribosyl cyclases (CD38/CD157) and sirtuins. Two main strategies to increase NAD+ availability have arisen. These strategies are based on the utilization of NAD+ intermediates/precursors or the inhibition of the NAD+-consuming enzymes, PARPs and CD38. An increase in endogenous sirtuin activity seems to mediate the protective effect that enhancing NAD+ availability confers in several models of neurodegeneration and age-related diseases. FUTURE DIRECTIONS A growing body of evidence suggests the beneficial role of enhancing NAD+ availability in models of neurodegeneration. The challenge ahead is to establish the value and safety of the long-term use of these strategies for the treatment of neurodegenerative diseases. Antioxid. Redox Signal. 28, 1652-1668.

Abstract
SIGNIFICANCE Numerous studies have demonstrated the actions of reactive oxygen species (ROS) as regulators of several physiological processes. In this study, we discuss how redox signaling mechanisms operate to control different processes such as neuronal differentiation, oligodendrocyte differentiation, dendritic growth, and axonal growth. Recent Advances: Redox homeostasis regulates the physiology of neural stem cells (NSCs). Notably, the neuronal differentiation process of NSCs is determined by a change toward oxidative metabolism, increased levels of mitochondrial ROS, increased activity of NADPH oxidase (NOX) enzymes, decreased levels of Nrf2, and differential regulation of different redoxins. Furthermore, during the neuronal maturation processes, NOX and MICAL produce ROS to regulate cytoskeletal dynamics, which control the dendritic and axonal growth, as well as the axonal guidance. CRITICAL ISSUES The redox homeostasis changes are, in part, attributed to cell metabolism and compartmentalized production of ROS, which is regulated, sensed, and transduced by different molecules such as thioredoxins, glutaredoxins, peroxiredoxins, and nucleoredoxin to control different signaling pathways in different subcellular regions. The study of how these elements cooperatively act is essential for the understanding of nervous system development, as well as the application of regenerative therapies that recapitulate these processes. FUTURE DIRECTIONS The information about these topics in the last two decades leads us to the conclusion that the role of ROS signaling in development of the nervous system is more important than it was previously believed and makes clear the importance of exploring in more detail the mechanisms of redox signaling.

Abstract
BACKGROUND The CD38/cyclic ADP-ribose (cADPR) pathway plays a role in various central nervous system diseases and in morphine tolerance, but its role in local anesthetic intoxication is unknown. The aim of this study was to determine the role of the CD38/cADPR pathway in ropivacaine-induced convulsion. METHODS Forty male Sprague-Dawley rats were randomly divided into five groups (n = 8 per group): sham group, ropivacaine group, ropivacaine+8-Br-cADPR (5 nmol) group, ropivacaine+8-Br-cADPR (10 nmol) group, and ropivacaine+8-Br-cADPR (20 nmol) group (no rats died). Rats were intracerebroventricularly injected with normal saline or 8-Br-cADPR 30 min before receiving an intraperitoneal injection of ropivacaine. Electroencephalography and convulsion behavior scores were recorded. The hippocampus was harvested from each group and subjected to nicotinamide adenine dinucleotide and cADPR assays, Western blotting analysis, and malondialdehyde (MDA) and superoxide dismutase (SOD) assays. RESULTS Intraperitoneal injection of ropivacaine (33.8 mg/kg) induced convulsions in rats. CD38 and cADPR levels increased significantly following ropivacaine-induced convulsion (P = 0.031 and 0.020, respectively, compared with the sham group). Intraventricular injection of 8-Br-cADPR (5, 10, and 20 nmol) significantly prolonged convulsion latency (P = 0.037, 0.034, and 0.000, respectively), reduced convulsion duration (P = 0.005, 0.005, and 0.005, respectively), and reduced convulsion behavior scores (P = 0.015, 0.015, and 0.000, respectively). Intraventricular injection of 8-Br-cADPR (10 nmol) also increased the B-cell lymphoma-2 (Bcl-2)/Bcl-2-associated X protein ratio (P = 0.044) and reduced cleaved Caspase 3/Caspase 3 ratio, inducible nitric oxide synthase, MDA and SOD levels (P = 0.014, 0.044, 0.001, and 0.010, respectively) compared with the ropivacaine group. CONCLUSIONS The CD38/cADPR pathway is activated in ropivacaine-induced convulsion. Inhibiting this pathway alleviates ropivacaine-induced convulsion and protects the brain from apoptosis and oxidative stress.

TRPC3 is required for the survival, pluripotency and neural differentiation of mouse embryonic stem cells (mESCs). SCIENCE CHINA-LIFE SCIENCES 2018; 61:253-265. [PMID: 29392682 DOI: 10.1007/s11427-017-9222-9] [Citation(s) in RCA: 8] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Subscribe] [Scholar Register] [Received: 08/10/2017] [Accepted: 11/06/2017] [Indexed: 12/22/2022]
Abstract
Transient receptor potential canonical subfamily member 3 (TRPC3) is known to be important for neural development and the formation of neuronal networks. Here, we investigated the role of TRPC3 in undifferentiated mouse embryonic stem cells (mESCs) and during the differentiation of mESCs into neurons. CRISPR/Cas9-mediated knockout (KO) of TRPC3 induced apoptosis and the disruption of mitochondrial membrane potential both in undifferentiated mESCs and in those undergoing neural differentiation. In addition, TRPC3 KO impaired the pluripotency of mESCs. TRPC3 KO also dramatically repressed the neural differentiation of mESCs by inhibiting the expression of markers for neural progenitors, neurons, astrocytes and oligodendrocytes. Taken together, our new data demonstrate an important function of TRPC3 with regards to the survival, pluripotency and neural differentiation of mESCs.

Abstract
Reactive oxygen species are involved in both physiological and pathological processes including neurodegeneration and cancer. Therefore, cells have developed scavenging mechanisms to maintain redox homeostasis under control. Tumor suppressor genes play a critical role in the regulation of antioxidant genes. Here, we investigated whether the tumor suppressor gene TAp73 is involved in the regulation of metabolic adaptations triggered in response to oxidative stress. H2O2 treatment resulted in numerous biochemical changes in both control and TAp73 knockout (TAp73−/−) mouse embryonic fibroblasts, however the extent of these changes was more pronounced in TAp73−/− cells when compared to control cells. In particular, loss of TAp73 led to alterations in glucose, nucleotide and amino acid metabolism. In addition, H2O2 treatment resulted in increased pentose phosphate pathway (PPP) activity in null mouse embryonic fibroblasts. Overall, our results suggest that in the absence of TAp73, H2O2 treatment results in an enhanced oxidative environment, and at the same time in an increased pro-anabolic phenotype. In conclusion, the metabolic profile observed reinforces the role of TAp73 as tumor suppressor and indicates that TAp73 exerts this function, at least partially, by regulation of cellular metabolism.

Abstract
Respiratory syncytial virus (RSV) is the most common cause of hospitalization due to bronchiolitis in infants. Although the mechanisms behind this association are not completely elucidated, they appear to involve an excessive immune response causing lung pathology. Understanding the host response to RSV infection may help in the identification of targets for therapeutic intervention. We infected in-vitro human monocyte-derived dendritic cells (DCs) with RSV and analysed various aspects of the cellular response. We found that RSV induces in DCs the expression of CD38, an ectoenzyme that catalyses the synthesis of cyclic ADPR (cADPR). Remarkably, CD38 was under the transcriptional control of RSV-induced type I interferon (IFN). CD38 and a set of IFN-stimulated genes (ISGs) were inhibited by the anti-oxidant N-acetyl cysteine. When CD38-generated cADPR was restrained by 8-Br-cADPR or kuromanin, a flavonoid known to inhibit CD38 enzymatic activity, RSV-induced type I/III IFNs and ISGs were markedly reduced. Taken together, these results suggest a key role of CD38 in the regulation of anti-viral responses. Inhibition of CD38 enzymatic activity may represent an encouraging approach to reduce RSV-induced hyperinflammation and a novel therapeutic option to treat bronchiolitis.

Abstract
BACKGROUND The CD38/cADPR pathway has been found to play roles in various inflammatory conditions. However, whether CD38 plays a protective or detrimental effect in the central nervous system (CNS) is controversial. The aim of this study was to determine the effect of CD38/cADPR pathway in sepsis associated brain injury. MATERIALS AND METHODS Male Sprague-Dawley rats were undergone cecal ligation and puncture (CLP) or sham laparotomies. NAD+, cADPR and CD38 were measured in the hippocampus of septic rats at 0, 6, 12, 24, and 48h after CLP surgery. Rats were divided into the sham, CLP group, CLP+ CD38 expression lentivirus (CLP+ CD38 LV), CLP+ CD38 interference lentivirus (CLP+ CD38 Ri), CLP+ negative control lentivirus (CLP+NC) and the CLP+8-Br-cADPR groups. The Western blots of Bcl-2, Bax and iNOS, TUNEL assays, malondialdehyde (MDA) and superoxide dismutase (SOD) assays, transmission electron microscope analysis were performed in the hippocampus of rats. RESULTS NAD+, cADPR and CD38 levels increased significantly in the hippocampus of septic rats as early as 12-24h after CLP surgery. CD38 knockdown or blocking cADPR with 8-Br-cADPR significantly reduced apoptosis, MDA and SOD activity, iNOS expression and ultrastructural morphology damages in the hippocampus of septic rats. CONCLUSIONS In this study, we found that the CD38/cADPR pathway was activated in sepsis associated brain injury. Blocking this pathway protected the hippocampus from apoptosis, oxidative stress and ultrastructural morphology damages in septic rats.

Abstract
Cyclic adenosine diphosphoribose (cADPR), an endogenous nucleotide derived from nicotinamide adenine dinucleotide (NAD+), mobilizes Ca2+ release from endoplasmic reticulum (ER) via ryanodine receptors (RyRs), yet the bridging protein(s) between cADPR and RyRs remain(s) unknown. Here we synthesized a novel photoaffinity labeling (PAL) cADPR agonist, PAL-cIDPRE, and subsequently applied it to purify its binding proteins in human Jurkat T cells. We identified glyceraldehyde 3-phosphate dehydrogenase (GAPDH) as one of the cADPR binding protein(s), characterized the binding affinity between cADPR and GAPDH in vitro by surface plasmon resonance (SPR) assay, and mapped cADPR's binding sites in GAPDH. We further demonstrated that cADPR induces the transient interaction between GAPDH and RyRs in vivo and that GAPDH knockdown abolished cADPR-induced Ca2+ release. However, GAPDH did not catalyze cADPR into any other known or novel compound(s). In summary, our data clearly indicate that GAPDH is the long-sought-after cADPR binding protein and is required for cADPR-mediated Ca2+ mobilization from ER via RyRs.

Abstract
Embryonic stem cells (ESCs) are promising resources for both scientific research and clinical regenerative medicine. With regards to the latter, ESCs are especially useful for treating several neurodegenerative disorders. Two significant characteristics of ESCs, which make them so valuable, are their capacity for self-renewal and their pluripotency, both of which are regulated by the integration of various signaling pathways. Intracellular Ca(2+) signaling is involved in several of these pathways. It is known to be precisely controlled by different Ca(2+) channels and pumps, which play an important role in a variety of cellular activities, including proliferation, differentiation and apoptosis. Here, we provide a review of the recent work conducted to investigate the function of Ca(2+) signaling in the self-renewal and the neural differentiation of ESCs. Specifically, we describe the role of intracellular Ca(2+) mobilization mediated by RyRs (ryanodine receptors); by cADPR (cyclic adenosine 5'-diphosphate ribose) and CD38 (cluster of differentiation 38/cADPR hydrolase); and by NAADP (nicotinic acid adenine dinucleotide phosphate) and TPC2 (two pore channel 2). We also discuss the Ca(2+) influx mediated by SOCs (store-operated Ca(2+) channels), TRPCs (transient receptor potential cation channels) and LTCC (L-type Ca(2+) channels) in the pluripotent ESCs as well as in neural differentiation of ESCs. Moreover, we describe the integration of Ca(2+) signaling in the other signaling pathways that are known to regulate the fate of ESCs.
