Abstract
BACKGROUND Post-streptococcal glomerulonephritis (PSGN) is a consequence of the infection by group A beta-hemolytic streptococcus. During this infection, various immunological processes generated by streptococcal antigens are triggered, such as the induction of antibodies and immune complexes. This activation of the immune system involves both innate and acquired immunity. The immunological events that occur at the renal level lead to kidney damage with chronic renal failure as well as resolution of the pathological process (in most cases). Angiotensin II (Ang II) is a molecule with vasopressor and pro-inflammatory capacities, being an important factor in various inflammatory processes. During PSGN some events are defined that make Ang II conceivable as a molecule involved in the inflammatory processes during the disease. CONCLUSION This review is focused on defining which reported events would be related to the presence of this hormone in PSGN.

Abstract
Glyceraldehyde 3-phosphate dehydrogenase (GAPDH) is a crucial enzyme in glycolysis, an essential metabolic pathway for carbohydrate metabolism across all living organisms. Recent research indicates that phosphorylating GAPDH exhibits various moonlighting functions, contributing to plant growth and development, autophagy, drought tolerance, salt tolerance, and bacterial/viral diseases resistance. However, in rapeseed (Brassica napus), the role of GAPDHs in plant immune responses to fungal pathogens remains unexplored. In this study, 28 genes encoding GAPDH proteins were revealed in B. napus and classified into three distinct subclasses based on their protein structural and phylogenetic relationships. Whole-genome duplication plays a major role in the evolution of BnaGAPDHs. Synteny analyses revealed orthologous relationships, identifying 23, 26, and 26 BnaGAPDH genes with counterparts in Arabidopsis, Brassica rapa, and Brassica oleracea, respectively. The promoter regions of 12 BnaGAPDHs uncovered a spectrum of responsive elements to biotic and abiotic stresses, indicating their crucial role in plant stress resistance. Transcriptome analysis characterized the expression profiles of different BnaGAPDH genes during Sclerotinia sclerotiorum infection and hormonal treatment. Notably, BnaGAPDH17, BnaGAPDH20, BnaGAPDH21, and BnaGAPDH22 exhibited sensitivity to S. sclerotiorum infection, oxalic acid, hormone signals. Intriguingly, under standard physiological conditions, BnaGAPDH17, BnaGAPDH20, and BnaGAPDH22 are primarily localized in the cytoplasm and plasma membrane, with BnaGAPDH21 also detectable in the nucleus. Furthermore, the nuclear translocation of BnaGAPDH20 was observed under H2O2 treatment and S. sclerotiorum infection. These findings might provide a theoretical foundation for elucidating the functions of phosphorylating GAPDH.

Abstract
Type 2 diabetes (T2D) is associated with a plethora of comorbidities, including osteoporosis, which occurs due to an imbalance between bone resorption and formation. Numerous mechanisms have been explored to understand this association, including the renin-angiotensin-aldosterone system (RAAS). An upregulated RAAS has been positively correlated with T2D and estrogen deficiency in comorbidities such as osteoporosis in humans and experimental studies. Therefore, research has focused on these associations in order to find ways to improve glucose handling, osteoporosis and the downstream effects of estrogen deficiency. Upregulation of RAAS may alter the bone microenvironment by altering the bone marrow inflammatory status by shifting the osteoprotegerin (OPG)/nuclear factor kappa-Β ligand (RANKL) ratio. The angiotensin-converting-enzyme/angiotensin II/Angiotensin II type 1 receptor (ACE/Ang II/AT1R) has been evidenced to promote osteoclastogenesis and decrease osteoblast formation and differentiation. ACE/Ang II/AT1R inhibits the wingless-related integration site (Wnt)/β-catenin pathway, which is integral in bone formation. While a lot of literature exists on the effects of RAAS and osteoporosis on T2D, the work is yet to be consolidated. Therefore, this review looks at RAAS activity in relation to osteoporosis and T2D. This review also highlights the relationship between RAAS activity, osteoporosis and estrogen deficiency in T2D.

Abstract
About three decades ago, researchers suggested that metabolic enzymes participate in cellular processes that are unrelated to their catalytic activity, and the term "moonlighting functions" was proposed. Recently developed advanced technologies in the field of RNA interactome capture now unveil the unexpected RNA binding activity of many metabolic enzymes, as exemplified here for the enzymes of glycolysis. Although for most of these proteins a precise binding mechanism, binding conditions, and physiological relevance of the binding events still await in-depth clarification, several well explored examples demonstrate that metabolic enzymes hold crucial functions in post-transcriptional regulation of protein synthesis. This widely conserved RNA-binding function of glycolytic enzymes plays major roles in controlling cell activities. The best explored examples are glyceraldehyde 3-phosphate dehydrogenase, enolase, phosphoglycerate kinase, and pyruvate kinase. This review summarizes current knowledge about the RNA-binding activity of the ten core enzymes of glycolysis in plant, yeast, and animal cells, its regulation and physiological relevance. Apparently, a tight bidirectional regulation connects core metabolism and RNA biology, forcing us to rethink long established functional singularities.

Abstract
Tumour-associated angiogenesis plays a critical role in metastasis, the main cause of malignancy-related death. Extracellular vesicles (EVs) can regulate angiogenesis to participate in tumour metastasis. Our previous study showed that EVs rich in HAX1 are associated with in metastasis of nasopharyngeal carcinoma (NPC). However, the mechanism by which HAX1 of EVs promotes metastasis and angiogenesis is unclear. In this study, we demonstrated that EVs rich in HAX1 promote angiogenesis phenotype by activating the FAK pathway in endothelial cells (ECs) by increasing expression level of ITGB6. The expression level of HAX1 is markedly correlated with microvessel density (MVDs) in NPC and head and neck cancers based on an analysis of IHC. In addition to a series of in vitro cellular analyses, in vivo models revealed that HAX1 was correlated with migration and blood vessel formation of ECs, and metastasis of NPC. Using ribosome profiling, we found that HAX1 regulates the FAK pathway to influence microvessel formation and promote NPC metastasis by enhancing the translation efficiency of ITGB6. Our findings demonstrate that HAX1 can be used as an important biomarker for NPC metastasis, providing a novel basis for antiangiogenesis therapy in clinical settings.

Abstract
Glyceraldehyde-3-phosphate dehydrogenase (GAPDH) is a moonlighting protein exhibiting distinct activities apart from its classical role in glycolysis. Regulation of its moonlighting functions and its subcellular localization may be dependent on its posttranslational modification (PTM). The latter include its phosphorylation, which is required for its role in intermembrane trafficking, synaptic transmission and cancer survival; nitrosylation, which is required for its function in apoptosis, heme metabolism and the immune response; acetylation which is necessary for its modulation of apoptotic gene regulation; and N-acetylglucosamine modification which may induce changes in GAPDH oligomeric structure. These findings suggest a structure function relationship between GAPDH posttranslational modification and its diverse moonlighting activities.

Abstract
BACKGROUND Glyceraldehyde-3-phosphate Dehydrogenase (GAPDH) is a unique enzyme that, besides its main function in glycolysis (catalysis of glyceraldehyde-3-phosphate oxidation), possesses a number of non-glycolytic activities. The present review summarizes information on the role of oxidative stress in the regulation of the enzymatic activity as well as non-glycolytic functions of GAPDH. METHODS Based on the analysis of literature data and the results obtained in our research group, mechanisms of the regulation of GAPDH functions through the oxidation of the sulfhydryl groups in the active site of the enzyme have been suggested. RESULTS Mechanism of GAPDH oxidation includes consecutive oxidation of the catalytic Cysteine (Cys150) into sulfenic, sulfinic, and sulfonic acid derivatives, resulting in the complete inactivation of the enzyme. The cysteine sulfenic acid reacts with reduced glutathione (GSH) to form a mixed disulfide (S-glutathionylated GAPDH) that further reacts with Cys154 yielding the disulfide bond in the active site of the enzyme. In contrast to the sulfinic and sulfonic acids, the mixed disulfide and the intramolecular disulfide bond are reversible oxidation products that can be reduced in the presence of GSH or thioredoxin. CONCLUSION Oxidation of sulfhydryl groups in the active site of GAPDH is unavoidable due to the enhanced reactivity of Cys150. The irreversible oxidation of Cys150 is prevented by Sglutathionylation and disulfide bonding with Cys154. The oxidation/reduction of the sulfhydryl groups in the active site of GAPDH can be used for regulation of glycolysis and numerous side activities of this enzyme including the induction of apoptosis.

Abstract
Moonlighting glyceraldehyde-3-phosphate dehydrogenase (GAPDH) exhibits multiple functions separate and distinct from its historic role in energy production. Further, it exhibits dynamic changes in its subcellular localization which is an a priori requirement for its multiple activities. Separately, moonlighting GAPDH may function in the pathology of human disease, involved in tumorigenesis, diabetes, and age-related neurodegenerative disorders. It is suggested that moonlighting GAPDH function may be related to specific modifications of its protein structure as well as the formation of GAPDH protein: protein or GAPDH protein: nucleic acid complexes.

Abstract
BACKGROUND We previously showed that glyceraldehyde-3-phosphate dehydrogenase (GAPDH) is S-glutathionylated in the presence of H2O2 and GSH. S-glutathionylation was shown to result in the formation of a disulfide bridge in the active site of the protein. In the present work, the possible biological significance of the disulfide bridge was investigated. METHODS Human recombinant GAPDH with the mutation C156S (hGAPDH_C156S) was obtained to prevent the formation of the disulfide bridge. Properties of S-glutathionylated hGAPDH_C156S were studied in comparison with those of the wild-type protein hGAPDH. RESULTS S-glutathionylation of hGAPDH and hGAPDH_C156S results in the reversible inactivation of the proteins. In both cases, the modification results in corresponding mixed disulfides between the catalytic Cys152 and GSH. In the case of hGAPDH, the mixed disulfide breaks down yielding Cys152-Cys156 disulfide bridge in the active site. In hGAPDH_C156S, the mixed disulfide is stable. Differential scanning calorimetry method showed that S-glutathionylation leads to destabilization of hGAPDH molecule, but does not affect significantly hGAPDH_C156S. Reactivation of S-glutathionylated hGAPDH in the presence of GSH and glutaredoxin 1 is approximately two-fold more efficient compared to that of hGAPDH_C156S. CONCLUSIONS S-glutathionylation induces the formation of Cys152-Cys156 disulfide bond in the active site of hGAPDH, which results in structural changes of the protein molecule. Cys156 is important for reactivation of S-glutathionylated GAPDH by glutaredoxin 1. GENERAL SIGNIFICANCE The described mechanism may be important for interaction between GAPDH and other proteins and ligands, involved in cell signaling.

Abstract
Glyceraldehyde-3-phosphate dehydrogenase (GAPDH) catalyses the sixth step of glycolysis, and is also known to perform other (moonlighting) activities in animal cells. We have earlier identified an additional GAPDH gene in Trichoderma virens genome. This gene is consistently associated with the vir cluster responsible for biosynthesis of a range of volatile sesquiterpenes in Trichoderma virens. This gene is also associated with an orthologous gene cluster in Aspergillus spp. Both glycolytic GAPDH and the vir cluster-associated GAPDH show more than 80% similarity with essentially conserved NAD+ cofactor- and substrate-binding sites. However, a conserved indel is consistently present only in GAPDH associated with the vir cluster, both in T. virens and Aspergillus spp. Using gene knockout, we demonstrate here that the vir cluster-associated GAPDH is involved in biosynthesis of volatile sesquiterpenes in T. virens. We thus, for the first time, elucidate the non-glycolytic role of a GAPDH in a fungal system, and also prove for the first time that a GAPDH, a primary metabolism protein, is involved in secondary metabolism.

Abstract
Portal hypertension (PH) is a major cause of morbidity and mortality in chronic liver disease. Infection and inflammation play a role in potentiating PH and pro-inflammatory cytokines, including TNF, are associated with severity of PH. In this study, cirrhotic bile duct ligated (BDL) rats with PH were treated with Infliximab (IFX, a monoclonal antibody against TNF) and its impact on modulation of vascular tone was assessed. BDL rats had increased TNF and NFkB compared to sham operated rats, and their reduction by IFX was associated with a reduction in portal pressure. IFX treatment also reduced hepatic oxidative stress, and biochemical markers of hepatic inflammation and injury. IFX treatment was associated with an improvement in eNOS activity and increased l-arginine/ADMA ratio and DDAH1 expression. In vitro analysis of HepG2 hepatocytes showed that DDAH1 protein expression is reduced by oxidative stress, and this is in part mediated by post-transcriptional regulation by the 3′UTR. This study supports a role for the DDAH1/ADMA axis on the effect of inflammation and oxidative stress in PH and provides insight for new therapies.

Abstract
BACKGROUND Glyceraldehyde-3-phosphate dehydrogenase (GAPDH) is a glycolytic protein involved in numerous non-glycolytic functions. S-glutathionylated GAPDH was revealed in plant and animal tissues. The role of GAPDH S-glutathionylation is not fully understood. METHODS Rabbit muscle GAPDH was S-glutathionylated in the presence of H2O2 and reduced glutathione (GSH). The modified protein was assayed by MALDI-MS analysis, differential scanning calorimetry, dynamic light scattering, and ultracentrifugation. RESULTS Incubation of GAPDH in the presence of H2O2 together with GSH resulted in the complete inactivation of the enzyme. In contrast to irreversible oxidation of GAPDH by H2O2, this modification could be reversed in the excess of GSH or dithiothreitol. By data of MALDI-MS analysis, the modified protein contained both mixed disulfide between Cys150 and GSH and the intrasubunit disulfide bond between Cys150 and Cys154 (different subunits of tetrameric GAPDH may contain different products). S-glutathionylation results in loosening of the tertiary structure of GAPDH, decreases its affinity to NAD+ and thermal stability. CONCLUSIONS The mixed disulfide between Cys150 and GSH is an intermediate product of S-glutathionylation: its subsequent reaction with Cys154 results in the intrasubunit disulfide bond in the active site of GAPDH. The mixed disulfide and the C150-C154 disulfide bond protect GAPDH from irreversible oxidation and can be reduced in the excess of thiols. Conformational changes that were observed in S-glutathionylated GAPDH may affect interactions between GAPDH and other proteins (ligands), suggesting the role of S-glutathionylation in the redox signaling. GENERAL SIGNIFICANCE The manuscript considers one of the possible mechanisms of redox regulation of cell functions.

Abstract
Hijacking of cellular biosynthetic pathways by human enveloped viruses is a shared molecular event essential for the viral lifecycle. In this study, the accumulating evidence of the importance of human glyceraldehyde-3-phosphate dehydrogenase (GAPDH) in the host secretory pathway led us to hypothesize that this moonlighting enzyme could play a key role in the lifecycle steps of two important Flaviviridae members, hepatitis C virus (HCV) and dengue virus (DENV). We used short interfering RNA (siRNA)-mediated knockdown of human GAPDH in Huh-7.5.1 cells- both pre- and post-HCV infection- to demonstrate that GAPDH is a host factor for HCV infection. siRNA-induced GAPDH knockdown performed pre-HCV infection inhibits HCV core production in infected cells and leads to a decrease in infectivity of the HCV-infected cell supernatants. siRNA-induced GAPDH knockdown performed post-HCV infection does not have an effect on HCV core abundance in infected cells, but does lead to a decrease in infectivity of the HCV-infected cell supernatants. Exogenous expression of V5-tagged human GAPDH, pre- and post-infection, increases the infectivity of HCV-infected cell supernatants, suggesting a role for GAPDH during HCV post-replication steps. Interestingly, siRNA-induced GAPDH knockdown in HCV replicon-harbouring cells had no effect on viral RNA replication. Importantly, we confirmed the important role of GAPDH in the HCV lifecycle using Huh-7-derived stable GAPDH-knockdown clones. Finally, siRNA-induced GAPDH knockdown inhibits intracellular DENV-2 E glycoprotein production in infected cells. Collectively, our findings suggest that the moonlighting enzyme, GAPDH, is an important host factor for HCV infection, and they support its potential role in the DENV lifecycle.

Abstract
Aside from its well-established role in glycolysis, glyceraldehyde-3-phosphate dehydrogenase (GAPDH) has been shown to possess many key functions in cells. These functions are regulated by protein oligomerization , biomolecular interactions, post-translational modifications , and variations in subcellular localization . Several GAPDH functions and regulatory mechanisms overlap with one another and converge around its role in intermediary metabolism. Several structural determinants of the protein dictate its function and regulation. GAPDH is ubiquitously expressed and is found in all domains of life. GAPDH has been implicated in many diseases, including those of pathogenic, cardiovascular, degenerative, diabetic, and tumorigenic origins. Understanding the mechanisms by which GAPDH can switch between its functions and how these functions are regulated can provide insights into ways the protein can be modulated for therapeutic outcomes.

Abstract
LGR4 is expressed in bone and has been shown to be involved in bone metabolism. Oxidative stress is one of the key issues in pathophysiology of osteoporosis. However, the link between Lgr4 and oxidative stress has not been known. Therefore, effects of hydrogen peroxide on Lgr4 expression in osteoblasts were examined. Hydrogen peroxide treatment suppressed the levels of Lgr4 mRNA expression in an osteoblastic cell line, MC3T3-E1. The suppressive effects were not obvious at 0.1 mM, while 1 mM hydrogen peroxide suppressed Lgr4 expression by more than 50%. Hydrogen peroxide treatment suppressed Lgr4 expression within 12 h and this suppression lasted at least up to 48 h. Hydrogen peroxide suppression of Lgr4 expression was still observed in the presence of a transcription inhibitor but was no longer observed in the presence of a protein synthesis inhibitor. Although Lgr4 expression in osteoblasts is enhanced by BMP2 treatment as reported before, hydrogen peroxide treatment suppressed Lgr4 even in the presence of BMP2. Finally, hydrogen peroxide suppressed Lgr4 expression in primary cultures of osteoblasts similarly to MC3T3-E1 cells. These date indicate that hydrogen peroxide suppresses Lgr4 expression in osteoblastic cells. J. Cell. Physiol. 232: 1761-1766, 2017. © 2016 Wiley Periodicals, Inc.

Abstract
Abnormal expressions of sodium channel SCN1A and SCN3A genes alter neural excitability that are believed to contribute to the pathogenesis of epilepsy, a long-term risk of recurrent seizures. Ketogenic diet (KD), a high-fat and low-carbohydrate treatment for difficult-to-control (refractory) epilepsy in children, has been suggested to reverse gene expression patterns. Here, we reveal a novel role of GAPDH on the posttranscriptional regulation of mouse Scn1a and Scn3a expressions under seizure and KD conditions. We show that GAPDH binds to a conserved region in the 3' UTRs of human and mouse SCN1A and SCN3A genes, which decreases and increases genes' expressions by affecting mRNA stability through SCN1A 3' UTR and SCN3A 3' UTR, respectively. In seizure mice, the upregulation and phosphorylation of GAPDH enhance its binding to the 3' UTR, which lead to downregulation of Scn1a and upregulation of Scn3a. Furthermore, administration of KD generates β-hydroxybutyric acid which rescues the abnormal expressions of Scn1a and Scn3a by weakening the GAPDH's binding to the element. Taken together, these data suggest that GAPDH-mediated expression regulation of sodium channel genes may be associated with epilepsy and the anticonvulsant action of KD.

Abstract
Abstract
Introduction: To identify novel pathways involved in the pathogenesis of ketosis, an isobaric tag for relative and absolute quantitation/mass spectrometry was used to define differences in protein expression profiles between healthy dairy cows and those with clinical or subclinical ketosis.
Material and Methods: To define the novel pathways of ketosis in cattle, the differences in protein expression were analysed by bioinformatics. Go Ontology and Pathway analysis were carried out for enrich the role and pathway of the different expression proteins between healthy dairy cows and those with clinical or subclinical ketosis.
Results: Differences were identified in 19 proteins, 16 of which were relatively up-regulated while the remaining 3 were relatively down-regulated. Sorbitol dehydrogenase (SORD) and glyceraldehyde-3-phosphate dehydrogenase (G3PD) were up-regulated in cattle with ketosis. SORD and G3PD promoted glycolysis. These mechanisms lead to pyruvic acid production increase and ketone body accumulation.
Conclusion: The novel pathways of glycolysis provided new evidence for the research of ketosis.

Abstract
As the formation of ribonucleoprotein complexes is a major mechanism of angiotensin II type 1 receptor (AT1R) regulation, we sought to identify novel AT1R mRNA binding proteins. By affinity purification and mass spectroscopy, we identified TIA-1. This interaction was confirmed by colocalization of AT1R mRNA and TIA-1 by FISH and immunofluorescence microscopy. In immunoprecipitates of endogenous TIA- 1, reverse transcription-PCR amplified AT1R mRNA. TIA-1 has two binding sites within AT1R 3'-UTR. The binding site proximal to the coding region is glyceraldehyde-3-phosphate dehydrogenase (GAPDH)-dependent whereas the distal binding site is not. TIA-1 functions as a part of endoplasmic reticulum (ER) stress response leading to stress granule (SG) formation and translational silencing. We and others have shown that AT1R expression is increased by ER stress-inducing factors. In unstressed cells, TIA-1 binds to AT1R mRNA and decreases AT1R protein expression. Fluorescence microscopy shows that ER stress induced by thapsigargin leads to the transfer of TIA-1 to SGs. In FISH analysis AT1R mRNA remains in the cytoplasm and no longer colocalizes with TIA-1. Thus, release of TIA-1-mediated suppression by ER stress increases AT1R protein expression. In conclusion, AT1R mRNA is regulated by TIA-1 in a ER stress-dependent manner.

Abstract
The glycolytic protein, glyceraldehyde-3-phosphate dehydrogenase (GAPDH), has a vast array of extraglycolytic cellular functions, including interactions with nucleic acids. GAPDH has been implicated in the translocation of transfer RNA (tRNA), the regulation of cellular messenger RNA (mRNA) stability and translation, as well as the regulation of replication and gene expression of many single-stranded RNA viruses. A growing body of evidence supports GAPDH-RNA interactions serving as part of a larger coordination between intermediary metabolism and RNA biogenesis. Despite the established role of GAPDH in nucleic acid regulation, it is still unclear how and where GAPDH binds to its RNA targets, highlighted by the absence of any conserved RNA-binding sequences. This review will summarize our current understanding of GAPDH-mediated regulation of RNA function.

Abstract
DNA alkylating drugs have been used in clinics for more than seventy years. The diversity of their mechanism of action (major/minor groove; mono-/bis-alkylation; intra-/inter-strand crosslinks; DNA stabilization/destabilization, etc.) has undoubtedly major consequences on the cellular response to treatment. The aim of this review is to highlight the variety of established protein recognition of DNA adducts to then particularly focus on glyceraldehyde-3-phosphate dehydrogenase (GAPDH) function in DNA adduct interaction with illustration using original experiments performed with S23906-1/DNA adduct. The introduction of this review is a state of the art of protein/DNA adducts recognition, depending on the major or minor groove orientation of the DNA bonding as well as on the molecular consequences in terms of double-stranded DNA maintenance. It reviews the implication of proteins from both DNA repair, transcription, replication and chromatin maintenance in selective DNA adduct recognition. The main section of the manuscript is focusing on the implication of the moonlighting protein GAPDH in DNA adduct recognition with the model of the peculiar DNA minor groove alkylating and destabilizing drug S23906-1. The mechanism of action of S23906-1 alkylating drug and the large variety of GAPDH cellular functions are presented prior to focus on GAPDH direct binding to S23906-1 adducts.

Abstract
Glyceraldehyde-3-phosphate dehydrogenase (GAPDH) is an enzyme best known for its role in glycolysis. However, extra-glycolytic functions of GAPDH have been described, including regulation of protein expression via RNA binding. GAPDH binds to numerous adenine-uridine rich elements (AREs) from various mRNA 3'-untranslated regions in vitro and in vivo despite its lack of a canonical RNA binding motif. How GAPDH binds to these AREs is still unknown. Here we discovered that GAPDH binds with high affinity to the core ARE from tumor necrosis factor-α mRNA via a two-step binding mechanism. We demonstrate that a mutation at the GAPDH dimer interface impairs formation of the second RNA-GAPDH complex and leads to changes in the RNA structure. We investigated the effect of this interfacial mutation on GAPDH oligomerization by crystallography, small-angle x-ray scattering, nano-electrospray ionization native mass spectrometry, and hydrogen-deuterium exchange mass spectrometry. We show that the mutation does not significantly affect GAPDH tetramerization as previously proposed. Instead, the mutation promotes short-range and long-range dynamic changes in regions located at the dimer and tetramer interface and in the NAD(+) binding site. These dynamic changes are localized along the P axis of the GAPDH tetramer, suggesting that this region is important for RNA binding. Based on our results, we propose a model for sequential GAPDH binding to RNA via residues located at the dimer and tetramer interfaces.

Abstract
Multifunctional proteins provide a new mechanism to expand exponentially cell information and capability beyond that indicated by conventional gene analyses. As such, examination of their structure-function relationships provides a means to define the mechanisms through which cells accomplish critical yet disparate activities required for cell viability and survival. Glyceraldehyde-3-phosphate dehydrogenase (GAPDH) may be considered the quintessential multidimensional protein which exhibits a variety of functions unrelated to its classical role in energy production. This review discusses new insights into the structure-function mechanisms through which defined GAPDH amino acid domains are utilized for its diverse activities, the importance of its post-translational modification, and, intriguingly, the logic inherent in the presence or the absence of specific signaling domains.

Abstract
Cancer cells depend on an altered energy metabolism characterized by increased rates of both glycolysis and glutaminolysis. Accordingly, corresponding key metabolic enzymes are overexpressed or hyperactivated. As a result, this newly acquired metabolic profile determines most other cancer hallmarks including resistance to cell death. Recent findings highlighted metabolic enzymes as direct modulators of cell death pathways. Conversely, key mediators of cell death mechanisms are emerging as new binding partners of glycolytic actors; moreover, there is evidence that metabolic regulators re-localize to specific subcellular compartments or organelles to modulate various types of cell demise. The final outcome is the resistance against cell death programs. Current findings give a new meaning to metabolic pathways and allow understanding how they affect cancer-specific pathological alterations. Furthermore, they shed light on potentially targetable functions of metabolic actors to restore susceptibility of cancer cells to death. Here, we discuss an emerging interplay between cell metabolism and cell death, focusing on interactions that may offer new options of targeted therapies in cancer treatment involving more specifically hexokinases and glyceraldehyde-3-phosphate dehydrogenase.

Abstract
Human Tudor staphylococcal nuclease (Tudor-SN) interacts with the G3BP protein and is recruited into stress granules (SGs), the main type of discrete RNA-containing cytoplasmic foci structure that is formed under stress conditions. Here, we further demonstrate that Tudor-SN binds and co-localizes with AGTR1-3'UTR (3'-untranslated region of angiotensin II receptor, type 1 mRNA) into SG. Tudor-SN plays an important role in the assembly of AGTR1-3'UTR granules. Moreover, endogenous Tudor-SN knockdown can decrease the recovery kinetics of AGTR1-3'UTR granules. Collectively, our data indicate that Tudor-SN modulates the kinetics of AGTR1-3'UTR granule formation, which provides an additional biological role of Tudor-SN in RNA metabolism during stress.

Abstract
Mutations in the SCN1A gene-encoding voltage-gated sodium channel α-I subunit (Nav1.1) cause various spectrum of epilepsies including Dravet syndrome (DS), a severe and intractable form. A large number of SCN1A mutations identified from the DS patients lead to the loss of function or truncation of Nav1.1 that result in a haploinsufficiency effects, indicating that the exact expression level of SCN1A should be essential to maintain normal brain function. In this study, we have identified five variants c.*1025T>C, c.*1031A>T, c.*1739C>T, c.*1794C>T and c.*1961C>T in the SCN1A 3' UTR in the patients with DS. The c.*1025T>C, c.*1031A>T and c.*1794C>T are conserved among different species. Of all the five variants, only c.*1794C>T is a novel variant and alters the predicted secondary structure of the 3' UTR. We also show that glyceraldehyde-3-phosphate dehydrogenase (GAPDH) only binds to the 3' UTR sequence containing the mutation allele 1794U but not the wild-type allele 1794C, indicating that the mutation allele forms a new GAPDH-binding site. Functional analyses show that the variant negatively regulates the reporter gene expression by affecting the mRNA stability that is mediated by GAPDH's binding, and this phenomenon could be reversed by shRNA-induced GAPDH knockdown. These findings suggest that GAPDH and the 3'-UTR variant are involved in regulating SCN1A expression at post-transcriptional level, which may provide an important clue for further investigating on the relationship between 3'-UTR variants and SCN1A-related diseases.

Abstract
Glyceraldehyde-3-phosphate dehydrogenase (GAPDH) has long been recognized as an important enzyme for energy metabolism and the production of ATP and pyruvate through anaerobic glycolysis in the cytoplasm. Recent studies have shown that GAPDH has multiple functions independent of its role in energy metabolism. Although increased GAPDH gene expression and enzymatic function is associated with cell proliferation and tumourigenesis, conditions such as oxidative stress impair GAPDH catalytic activity and lead to cellular aging and apoptosis. The mechanism(s) underlying the effects of GAPDH on cellular proliferation remains unclear, yet much evidence has been accrued that demonstrates a variety of interacting partners for GAPDH, including proteins, various RNA species and telomeric DNA. The present mini review summarizes recent findings relating to the extraglycolytic functions of GAPDH and highlights the significant role this enzyme plays in regulating both cell survival and apoptotic death.

Abstract
Multidimensional proteins such as glyceraldehyde-3-phosphate dehydrogenase (GAPDH) exhibit distinct activities unrelated to their originally identified functions. Apart from glycolysis, GAPDH participates in iron metabolism, membrane trafficking, histone biosynthesis, the maintenance of DNA integrity and receptor mediated cell signaling. Further, multifunctional proteins exhibit distinct changes in their subcellular localization reflecting their new activities. As such, GAPDH is not only a cytosolic protein but is localized in the membrane, the nucleus, polysomes, the ER and the Golgi. In addition, although the initial subcellular localizations of multifunctional proteins may be of significance, dynamic changes in intracellular distribution may occur as a consequence of those new activities. As such, regulatory mechanisms may exist through which cells control multifunctional protein expression as a function of their subcellular localization. The temporal sequence through which subcellular translocation and the acquisition of new GAPDH functions is considered as well as post-translational modification as a basis for its intracellular transport.

Abstract
We found that a 38-kDa protein was released from erythrocyte membranes lysed by hemolysin of Prevotella oris, although hypotonic hemolysis did not show such a phenomenon. The 38-kDa protein was identified as glyceraldehyde-3-phosphate dehydrogenase (GAPDH) by N-terminal amino acid sequencing. This study discusses the relationship between GAPDH and hemolysis.

Abstract
Müller cells, the primary glial cells are a crucial component of the retinal tissue performing a wide range of functions including maintaining the blood-retinal barrier. Several studies suggest that diabetes leads to Müller cell dysfunction and loss. The pathophysiology of hyperglycemia-induced cellular injury of Müller cells remains only poorly understood. Recently, the concept that translocation of the predominantly cytosolic glycolytic enzyme glyceraldehyde-3-phosphate dehydrogenase (GAPDH) to the nucleus and its accumulation in this cellular compartment alters transcriptional events associated with cell death induction has gained major interest. High glucose conditions induce nuclear translocation and accumulation of GAPDH in the nucleus of Müller cells in vivo and in vitro. With regards to Müller cell dysfunction, the effects of nuclear accumulation of GAPDH are multifaceted. Considering the functional versatility of GAPDH including gene regulation, DNA repair, telomere protection, etc., it is of immense importance to explore possible GAPDH actions to unravel the mysteries around the role of GAPDH in hyperglycemia-induced cellular changes in order to develop novel therapeutic strategies. Therefore, this review focuses on the molecular events associated with the nuclear translocation of GAPDH and how it affects the fate of Müller cells in diabetes.

Abstract
Angiotensin II type 1 receptor (AT1R) has a pathophysiological role in hypertension, atherosclerosis and heart failure. Type 2 diabetes is hyperinsulinemic state and a major risk factor for atherosclerosis and hypertension. It is known that hyperinsulinemia upregulates AT1R expression post-transcriptionally by increasing the half-life of AT1R mRNA, but little is known about the mechanism of this effect. In the present study, we first identified AT1R 3′-UTR as a mediator of insulin effect. Using 3′-UTR as a bait, we identified through analysis of insulin-stimulated cell lysates by affinity purification and mass spectrometry HuR as an insulin-regulated AT1R mRNA binding protein. By ribonucleoprotein immunoprecipitation, we found HuR binding to AT1R to be increased by insulin. Overexpression of HuR leads to increased AT1R expression in a 3′-UTR-dependent manner. Both insulin and HuR overexpression stabilize AT1R 3′-UTR and their responsive element within 3′-UTR are located within the same region. Cell fractionation demonstrated that insulin induced HuR translocation from nucleus to cytoplasm increased HuR binding to cytoplasmic AT1R 3′-UTR. Consistent with HuR translocation playing a mechanistic role in HuR effect, a reduction in the cytoplasmic levels of HuR either by silencing of HuR expression or by inhibition of HuR translocation into cytoplasm attenuated insulin response. These results show that HuR translocation to cytoplasm is enhanced by insulin leading to AT1R upregulation through HuR-mediated stabilization of AT1R mRNA.

Abstract
BACKGROUND New studies provide evidence that glyceraldehyde-3-phosphate dehydrogenase (GAPDH) is not simply a classical glycolytic protein of little interest. Instead, it is a multifunctional protein with significant activity in a number of fundamental cell pathways. GAPDH is a highly conserved gene and protein, with a single mRNA transcribed from a unique gene. Control mechanisms must exist which regulate its functional diversity. SCOPE OF REVIEW This review focuses on new, timely studies defining not only its diverse activities but also those which define the regulatory mechanisms through which those functions may be controlled. The reader is referred to the author's prior review for the consideration of past reports which first indicated GAPDH multiple activities (Sirover, Biochim. Biophys. Acta 1432 (1999) 159-184.) CONCLUSIONS These investigations demonstrate fundamental roles of GAPDH in vivo, dynamic changes in its subcellular localization, and the importance of posttranslational modifications as well as protein:protein interactions as regulatory control mechanisms. GENERAL SIGNIFICANCE GAPDH is the prototype "moonlighting" protein which exhibits activities distinct from their classically identified functions. Their participation in diverse cell pathways is essential. Regulatory mechanisms exist which control those diverse activities as well as changes in their subcellular localization as a consequence of those new functions.

Abstract
To investigate whether apelin-13 induced THP-1 monocytes (MCs) adhesion to ECV304 human umbilical vein endothelial cells (HUVECs) via 14-3-3 signaling transduction pathway and the potential novel physiological function and signaling transduction pathway of apelin-APJ, HUVECs ECV304 were cultured in DMEM and MCs THP-1 were cultured in RPMI 1640 medium. Monocyte adhesion and the expression of vascular cell adhesion molecule-1 (VCAM-1) and 14-3-3 were measured with monocyte adhesion assay and western blot analysis. Data showed that apelin-13 increased adhesion of MCs to HUVECs in a concentration- and time-dependent manner, which reached their peaks at 1 mM and 12 h, respectively. Similarly, apelin-13 induced the expression of HUVECs adhesion molecule, VCAM-1, in a concentration- and time-dependent manner, reached their peaks at 1 microM and 12 h, respectively. Apelin-13 induced the expression of 14-3-3 in a concentration- and timedependent manner, which reached their peaks at 1 mM and 5 min, respectively. Furthermore, the potent 14-3-3 inhibitor difopein significantly reduced the expression of 14-3-3 and VCAM-1 in apelin-13 stimulated HUVECs, and difopein significantly inhibited the effect of apelin-13 on induction of MCs adhesion to HUVECs. These data suggested that 14-3-3 mediated the induction of adhesion of MCs to HUVECs by Apelin-13.

Abstract
Ribonucleases (RNases) play a variety of cellular and biological roles in all three domains of life. In an attempt to perform RNA immuno-precipitation assays of Arabidopsis proteins, we found an EDTA-dependent RNase activity from Arabidopsis suspension tissue cultures. Further investigations proved that the EDTA-dependent RNase activity was plant specific. Characterization of the RNase activity indicated that it was insensitive to low pH and high concentration of NaCl. In the process of isolating the activity with cation exchange chromatography, we found that the EDTA dependency of the activity was lost. This led us to speculate that some metal ions, which inhibited the RNase activity, may be removed during cation exchange chromatography so that the nuclease activity was released. The EDTA dependency of the activity could be due to the ability of the EDTA chelating those metal ions, mimicking the effect of the cation exchange chromatography. Indeed, Zn(2+) strongly inhibited the activity, and the inhibition could be released by EDTA based on both in-solution and in-gel assays. In-gel assays identified two RNase activity bands. Mass spectrometry assays of those activity bands revealed more than 20 proteins. However, none of them has an apparent known nuclease domain, suggesting that one or more of those proteins might possess a currently uncharacterized nuclease domain. Our results may shed light on RNA metabolism in plants by introducing a novel plant-specific RNase activity.
