Abstract
This paper presents the initial exploration of the free radical scavenging capabilities of peptides derived from protein hydrolysates (PPH) obtained from Zingiber cassumunar rhizomes (Phlai). To replicate the conditions of gastrointestinal digestion, a combination of pepsin and pancreatin proteolysis was employed to generate these hydrolysates. Subsequently, the hydrolysate underwent fractionation using molecular weight cut-off membranes at 10, 5, 3, and 0.65 kDa. The fraction with a molecular weight less than 0.65 kDa exhibited the highest levels ABTS, DPPH, FRAP, and NO radical scavenging activity. Following this, RP-HPLC was used to further separate the fraction with a molecular weight less than 0.65 kDa into three sub-fractions. Among these, the F5 sub-fraction displayed the most prominent radical-scavenging properties. De novo peptide sequencing via quadrupole-time-of-flight-electron spin induction-mass spectrometry identified a pair of novel peptides: Asp-Gly-Ile-Phe-Val-Leu-Asn-Tyr (DGIFVLNY or DY-8) and Ile-Pro-Thr-Asp-Glu-Lys (IPTDEK or IK-6). Database analysis confirmed various properties, including biological activity, toxicity, hydrophilicity, solubility, and potential allergy concerns. Furthermore, when tested on the human adenocarcinoma colon (Caco-2) cell line, two synthetic peptides demonstrated cellular antioxidant activity in a concentration-dependent manner. These peptides were also assessed using the FITC Annexin V apoptosis detection kit with PI, confirming the induction of apoptosis. Notably, the DY-8 peptide induced apoptosis, upregulated mRNA levels of caspase-3, -8, and -9, and downregulated Bcl-2, as confirmed by real-time quantitative polymerase chain reaction (RT-qPCR). Western blot analysis indicated increased pro-apoptotic Bax expression and decreased anti-apoptotic Bcl-2 expression in Caco-2 cells exposed to the DY-8 peptide. Molecular docking analysis revealed that the DY-8 peptide exhibited binding affinity with Bcl-2, Bcl-xL, and Mcl-1, suggesting potential utility in combating colon cancer as functional food ingredients.

Abstract
In this study, we used traditional laboratory methods, bioinformatics, and cellular models to screen novel ACE inhibitory (ACEI) peptides with strong ACEI activity, moderate absorption rates, and multiple targets from bovine colostrum immunoglobulin G (IgG). The purified fraction of the compound proteinase hydrolysate of IgG showed good ACEI activity. After nano-UPLC-MS/MS identification and in silico analysis, eight peptides were synthesized and verified. Among them, SFYPDY, TSFYPDY, FSWF, WYQQVPGSGL, and GVHTFP were identified as ACEI peptides, as they exhibited strong ACEI activity (with IC50 values of 104.7, 80.0, 121.2, 39.8, and 86.3 μM, respectively). They displayed good stability in an in vitro simulated gastrointestinal digestion assay. In a Caco-2 monolayer model, SFYPDY, FSWF, and WYQQVPGSGL exhibited better absorption rates and lower IC50 values than the other peptides and were thereby identified as novel ACEI peptides. Subsequently, in a H2O2-induced endothelial dysfunction (ED) model based on HUVECs, SFYPDY, FSWF, and WYQQVPGSGL regulated ED by reducing apoptosis and ROS accumulation while upregulating NOS3 mRNA expression. Network pharmacology analysis and RT-qPCR confirmed that they regulated multiple targets. Overall, our results suggest that SFYPDY, FSWF, and WYQQVPGSGL can serve as novel multitarget ACEI peptides.

Abstract
Oleanolic acid (OA) is a natural triterpenoid with therapeutic potential for a multitude of diseases. However, the precise mechanism by which OA influences stress-induced apoptosis of intestinal epithelial cells remains elusive. Therefore, the effect of OA on intestinal diseases under stressful conditions and its possible mechanisms have been investigated. In a hydrogen peroxide (H2 O2 )-induced oxidative stress model, OA attenuated H2 O2 -induced apoptosis in a concentration-dependent manner. To investigate the underlying mechanisms, the gene expression profile of OA on IPEC-J2 cells was analyzed using an RNA sequencing system. Results from gene ontology and Kyoto encyclopedia of genes and genomes analysis confirmed that OA may mitigate the cytotoxic effects of H2 O2 by downregulating gene expression through the MAPK signaling pathway. Furthermore, Quantitative real-time polymerase chain reaction results validated the differentially expressed genes data. Western blot analysis further demonstrated that OA effectively suppressed the expression level of c-Jun protein induced by H2 O2 in IPEC-J2 cells. Collectively, our results indicate that OA pretreatment significantly attenuated H2 O2 -induced apoptosis in intestinal epithelial cells through suppressing c-Jun and MAPK pathway.

Abstract
Periodontitis is a type of chronic inflammatory oral disease characterized by the destruction of periodontal connective tissue and progressive alveolar bone resorption. As oxidative stress is the key cause of periodontitis in the early periodontal microenvironment, antioxidative therapy has been considered a viable treatment for periodontitis. However, more stable and effective reactive oxygen species (ROS)-scavenging nanomedicines are still highly needed due to the instability of traditional antioxidants. Herein, a new type of N-acetyl-l-cysteine (NAC)-derived red fluorescent carbonized polymer dots (CPDs) has been synthesized with excellent biocompatibility, which can serve as an extracellular antioxidant to scavenge ROS effectively. Moreover, NAC-CPDs can promote osteogenic differentiation in human periodontal ligament cells (hPDLCs) under H2 O2 stimulation. In addition, NAC-CPDs are capable of targeted accumulation in alveolar bone in vivo, reducing the level of alveolar bone resorption in periodontitis mice, as well as performing fluorescence imaging in vitro and in vivo. In terms of mechanism, NAC-CPDs may regulate redox homeostasis and promote bone formation in the periodontitis microenvironment by modulating the kelch-like ECH-associated protein l (Keap1)/nuclear factor erythroid 2-related factor 2 (Nrf2) pathway. This study provides a new strategy for the application of CPDs theranostic nanoplatform for periodontitis.

Abstract
Sarcopenia is an age-related progressive muscle disorder characterized by accelerated loss of muscle mass, strength, and function, which are important causes of physiological dysfunctions in the elderly. At present, the main alleviating method includes protein supplements to stimulate synthesis of muscle proteins. Food protein-derived peptides containing abundant branched-chain amino acids have a remarkable effect on the improvement of sarcopenia. Understanding the underlying molecular mechanism and clarifying the structure-activity relationship is essential for the mitigation of sarcopenia. This present review recaps the epidemiology, pathogenesis, diagnosis, and treatment of sarcopenia, which facilitates a comprehensive understanding of sarcopenia. Moreover, the latest research progress on food-derived antisarcopenic peptides is reviewed, including their antisarcopenic activity, molecular mechanism as well as structural characteristics. Food-derived bioactive peptides can indeed alleviate/mitigate sarcopenia. These antisarcopenic peptides play a pivotal role mainly by activating the PI3K/Akt/mTOR and MAPK pathways and inhibiting the ubiquitin-proteasome system and AMPK pathway, thus promoting the synthesis of muscle proteins and inhibiting their degradation. Antisarcopenic peptides alleviate sarcopenia via specific peptides, which may be absorbed into the circulation and exhibit their bioactivity in intact forms. The present review provides a theoretical reference for mitigation and prevention of sarcopenia by food protein-derived bioactive peptides.

Abstract
Despite the long-standing notion of "oxidative stress," as the main mediator of many diseases including male infertility induced by increased reactive oxygen species (ROS), recent evidence suggests that ROS levels are also increased by "reductive stress," due to over-accumulation of reductants. Damaging mechanisms, like guanidine oxidation followed by DNA fragmentation, could be observed following reductive stress. Excessive accumulation of the reductants may arise from excess dietary supplementation over driving the one-carbon cycle and transsulfuration pathway, overproduction of NADPH through the pentose phosphate pathway (PPP), elevated levels of GSH leading to impaired mitochondrial oxidation, or as a result NADH accumulation. In addition, lower availability of oxidized reductants like NAD+, oxidized glutathione (GSSG), and oxidized thioredoxins (Trx-S2) induce electron leakage leading to the formation of hydrogen peroxide (H2O2). In addition, a lower level of NAD+ impairs poly (ADP-ribose) polymerase (PARP)-regulated DNA repair essential for proper chromatin integrity of sperm. Because of the limited studies regarding the possible involvement of reductive stress, antioxidant therapy remains a central approach in the treatment of male infertility. This review put forward the concept of reductive stress and highlights the potential role played by reductive vs oxidative stress at pre-and post-testicular levels and considering dietary supplementation.

Abstract
Although amphibian-derived bioactive peptides have attracted increasing attention for their potential use in the treatment of photodamage, research is still in its infancy. In this study, we obtained a new antioxidant peptide, named OA-GI13 (GIWAPWPPRAGLC), from the skin of the odorous frog Odorrana andersonii and determined its effects on ultraviolet B (UVB)-induced skin photodamage as well as its possible molecular mechanisms. Results showed that OA-GI13 directly scavenged free radicals, maintained the viability of hydrogen peroxide-challenged keratinocytes, promoted the release of superoxide dismutase, catalase, and glutathione, and reduced the level of lactate dehydrogenase. Furthermore, topical application of OA-GI13 in mice alleviated dorsal skin erythema and edema and protected the skin against UVB irradiation by increasing antioxidant levels and decreasing peroxide, malondialdehyde, and 8-hydroxydeoxyguanosine levels. OA-GI13 also alleviated oxidative stress injury in vivo and in vitro, possibly by inhibiting p38 protein phosphorylation. Our study confirmed the anti-photodamage effects of this novel amphibian-derived peptide, thus providing a new molecule for the development of drugs and topical agents for the treatment of skin photodamage.

Cytoprotective Peptides from Blue Mussel Protein Hydrolysates: Identification and Mechanism Investigation in Human Umbilical Vein Endothelial Cells Injury. Mar Drugs 2021; 19:md19110609. [PMID: 34822480 PMCID: PMC8620150 DOI: 10.3390/md19110609] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/09/2021] [Revised: 10/23/2021] [Accepted: 10/26/2021] [Indexed: 12/21/2022] Open
Abstract
Cardiovascular disease represents a leading cause of mortality and is often characterized by the emergence of endothelial dysfunction (ED), a physiologic condition that takes place in the early progress of atherosclerosis. In this study, two cytoprotective peptides derived from blue mussel chymotrypsin hydrolysates with the sequence of EPTF and FTVN were purified and identified. Molecular mechanisms underlying the cytoprotective effects against oxidative stress which lead to human umbilical vein endothelial cells (HUVEC) injury were investigated. The results showed that pretreatment of EPTF, FTVN and their combination (1:1) in 0.1 mg/mL significantly reduced HUVEC death due to H2O2 exposure. The cytoprotective mechanism of these peptides involves an improvement in the cellular antioxidant defense system, as indicated by the suppression of the intracellular ROS generation through upregulation of the cytoprotective enzyme heme oxygenase-1. In addition, H2O2 exposure triggers HUVEC damage through the apoptosis process, as evidenced by increased cytochrome C release, Bax protein expression, and the elevated amount of activated caspase-3, however in HUVEC pretreated with peptides and their combination, the presence of those apoptotic stimuli was significantly decreased. Each peptide showed similar cytoprotective effect but no synergistic effect. Taken together, these peptides may be especially important in protecting against oxidative stress-mediated ED.

Abstract
Studies have shown that the peroxidation caused by oxygen free radicals is an important reason of vascular endothelial dysfunction and multiple diseases. In this study, active peptides (F2ds) were isolated from the fermentation product of rice dregs and its antioxidant effects were approved. Human umbilical vein endothelial cells (HUVECs) stimulated by H2O2 were used to evaluate the antioxidation effect and its molecular mechanism in the oxidative stress model. F2d protected H2O2-induced damage in HUVECs in a dosage-dependent manner. F2d can reduce the expression of Keap1, promote the expression of Nrf2, and activate the downstream target HO-1, NQO1, etc. It means F2d can modulate the Nrf2 signaling pathway. Using Nrf2 inhibitor ML385 to block the Nrf2 activation, the protective function of F2d is partially lost in the damage model. Our results indicated that F2d isolated from rice exerts antioxidant effects via the Nrf2 signaling pathway in H2O2-induced damage, and the work will benefit to develop functional foods.

Abstract
Rice bran protein (RBP) is a plant protein obtained from rice bran, a byproduct produced during rice milling process. It has been proved to be a high quality protein due to containing all of the essential amino acids and the content closing to the FAO/WHO recommended ideal pattern. Recent studies indicated that RBP and rice bran protein hydrolysates (RBPH) served variety biological functions. In this review, we summarized the classical functions of RBP and RBPH mediating antioxidant activity, chronic diseases prevention (such as antihypertensive effect, anti-diabetic effect, cholesterol-lowering activity), and anti-cancer effect. We also proposed their potential novel functions on anti-obesity effect, attenuating sarcopenia, promoting wound healing. Furthermore, the potential benefit to coronavirus disease 2019 (COVID-19) patients was put forward, which might provide new strategy for development and utilization of RBP and RBPH.

Abstract
As a conventional complication of sepsis, acute kidney injury (AKI) is characterized by high incidence and mortality. Effective management methods are still lacking. Quercetin belongs to a kind of flavonoids that exerts many functions, for example anti-inflammation and anti-fibrosis. However, its function in sepsis AKI is uncertain. Our study therefore set out to assess the function of quercetin in AKI mice model induced by lipopolysaccharide (LPS) and human proximal tubular cells (HK-2), including the potential mechanisms. Quercetin was loaded onto a biodegradable polymer carrier (nanoparticle) to enhance its bioavailability. The data showed that quercetin administration strikingly improved renal dysfunction and ameliorated tubular injury caused by LPS in mice. In mice model and in cultured cells, quercetin pretreatment obviously restrained LPS-triggered cell apoptosis and inflammation, including generation of various cytokines. Moreover, the results from mice model and cell model showed that quercetin could diminish IκBα and p65 phosphorylation after LPS treatment. The most significant observation of this study was that quercetin elevated the expression of Sirt1. Transfection of Sirt1 specific shRNA mitigated the suppression of quercetin on cell apoptosis, inflammation and of NF-κB activation triggered by LPS. Therefore, these sequels indicate that quercetin protects against sepsis-associated AKI by upregulation Sirt1 expression through quenching NF-κB activation and may be an encouraging therapeutic agent for patients with sepsis-associated AKI.

Abstract
The prevalence of metabolic syndrome (MetS) is presently an alarming public health problem globally. Oxidative stress has been postulated to be strongly correlated with MetS, such as type 2 diabetes, obesity, hypertension, cardiovascular diseases, and certain cancers. Cereals are important staple foods which account for a huge proportion of the human diet. However, owing to recent growing demand and the search for natural antioxidants for the prevention and management of MetS, cereal peptides have gained increasing attention for developing functional ingredients or foods with substantial antioxidant properties. This review explores the current production techniques for cereal peptidic antioxidants and their potential mechanism of action in the prevention and management of MetS.

Abstract
The role of the intestinal flora in health and disease has become a research hotspot. Compared with carbohydrates and fats, proteins are metabolized primarily by microbial fermentation in the intestine. The production of protein fermentation products and metabolites depends on the composition, diversity, and metabolism of the gut microbiota. Several protein fermentation products, including indoles, phenols, polyamines, hydrogen sulfide (H2S), amines, and carnitine, are toxic. This study analyzes the relationship between high-protein diets (HPDs), the intestinal microbiota, and human health and disease. Long-term HPDs increase the risk of intestinal diseases, type 2 diabetes (T2DM), obesity, central nervous system (CNS) diseases, and cardiovascular diseases (CVD) by producing toxic metabolites in the colon, including amines, H2S, and ammonia. Short-term HPDs have little effect on the metabolism of healthy individuals under 65 years old. However, meeting the protein requirements of individuals over 65 years old using HPDs is more challenging. The adverse effects of HPDs on athletes are minimal. Natural compounds (plant extracts, whose main constituents are polysaccharides and polyphenols), prebiotics, probiotics, and regular physical exercise improve gut dysbiosis and reduce disease risk.

Cytoprotective Role of Edible Seahorse ( Hippocampus abdominalis)-Derived Peptides in H 2O 2-Induced Oxidative Stress in Human Umbilical Vein Endothelial Cells. Mar Drugs 2021; 19:md19020086.

Abstract
Oxidative stress-induced endothelial dysfunction is strongly linked to the pathogenesis of cardiovascular diseases. A previous study revealed that seahorse hydrolysates ameliorated oxidative stress-mediated human umbilical vein endothelial cells (HUVECs) injury. However, the responsible compounds have not yet been identified. This study aimed to identify cytoprotective peptides and to investigate the molecular mechanism underlying the cytoprotective role in H2O2-induced HUVECs injury. After purification by gel filtration and HPLC, two peptides were sequenced by liquid chromatography-tandem mass spectrometry as HGSH (436.43 Da) and KGPSW (573.65 Da). The synthesized peptides and their combination (1:1 ratio) showed significant HUVECs protection effect at 100 μg/mL against H2O2-induced oxidative damage via significantly reducing intracellular reactive oxygen species (ROS). Two peptides and their combination treatment resulted in the increased heme oxygenase-1 (HO-1), a phase II detoxifying enzyme, through the activation of nuclear transcription factor-erythroid 2-related factor (Nrf2). Additionally, cell cycle and nuclear staining analysis revealed that two peptides and their combination significantly protected H2O2-induced cell death through antiapoptotic action. Two peptides and their combination treatment led to inhibit the expression of proapoptotic Bax, the release of cytochrome C into the cytosol, the activation of caspase 3 by H2O2 treatment in HUVECs, whereas antiapoptotic Bcl-2 expression was increased with concomitant downregulation of Bax/Bcl-2 ratio. Taken together, these results suggest that seahorse-derived peptides may be a promising agent for oxidative stress-related cardiovascular diseases.

Abstract
The adventitious roots of some plants will develop into tuberous roots which are widely used in many traditional Chinese medicines, including Pseudostellaria heterophylla. If adventitious root development is inhibited, the yield of Chinese medicinal materials will be reduced. Gibberellic acid is an important phytohormone that promotes plant growth and increases the resistance to drought, flood or disease. However, the effects of gibberellic acid on adventitious roots of Pseudostellaria heterophylla are not clear. Here, we reports GA3 suppressed adventitious root development of Pseudostellaria heterophylla by disturbing the balance of endogenesis hormones. By detecting the contents of various endogenous hormones, we found that the development of adventitious roots negatively correlated with the content of CA3 in tuberous roots. Exogenous GA3 treatment decreased the diameter of adventitious roots, but increased the length of adventitious roots of Pseudostellaria heterophylla. In contrast, blocking the biosynthesis of GA3 suppressed stem growth and promoted the xylem of tuberous roots development. Moreover, exogenous GA3 treatment resulted in imbalance of endogenesis hormones by regulating their synthesis-related genes expression in xylem of tuberous roots. These results suggest GA3 broke the established distribution of hormones by regulating synthesis, transport and biological activation of hormones to activate the apical meristem and suppress lateral meristem. Regulating GA3 signaling during adventitious roots development would be one of the possible ways to increase the yield of P. heterophylla.

Abstract
Effects of three compound growth regulators formulated with hypersensitivity protein, spermidine, salicylic acid and DA-6 (diethyl aminoethanol hexanoate) were tested on Xinjiang Jun Jujube. The doses of compound growth regulators were named as A (Hypersensitivity protein + spermidine + salicylic acid at the rate of 30 mg/L, 0.1 mmol/L and 0.25 mmol/L, respectively), B (Hypersensitive protein + spermidine + DA-6 at the rate of 30 mg/L, 0.1 mmol/L and 30 mg/L, respectively) and C (Spermidine + salicylic acid + DA-6 at the rate of 0.1 mmol/L, 0.25 mmol/L and 30 mg/L, respectively) versus a control group CK (contained only water). Fruit anatomical structures were compared after spraying. The results indicated that after spraying, the thickness of the upper and lower epidermal cells and the stratum corneum were increased. However, the upper epidermal stratum corneum became significantly thicker than the lower epidermis. Spraying with A improved the thickness of upper and lower epidermal cells, stratum corneum, the central vein and mesophyll. The cumulative effects of all these changes in leaf and fruit anatomical structures provided the resistance of the experimental fruit plant to stress. While the B and C regulators had inhibitory effects. So, the results obtained after spraying A category were beneficial to improve the stress resistance of the fruits. The length and cell area of pericarp and sarcocarp cells in the treatment groups were not changed significantly. But the length, number of sarcocarp cells and number of gaps were lower than those in the CK. This study can provide new measures for improving plant resistance in jujube production.

Abstract
This study investigated the effects of a physiologically active peptide derived from rice bran (KF-8) on oxidative stress in d-galactose (d-gal)-induced aging mice and the underlying molecular mechanisms. The aging model was developed by subcutaneously injecting Institute of Cancer Research mice with 250 mg/kg d-gal daily for 12 weeks and simultaneously treating them with 30 mg/kg KF-8. The relative expression levels of Nrf2 and NF-κB in the liver were determined by the western blot. The regulation of Nrf2 and NF-κBp65 by KF-8 was further validated in NIH/3T3 cells. Compared with the control mice, the aging mice had significantly decreased body weights as well as superoxide dismutase and GSH-Px levels (p < 0.05); however, they had increased serum reactive oxygen species and malondialdehyde and 8-hydroxydeoxyguanosine levels accompanied by aortic and brain injuries. They also had elevated RAGE, TLR4, IκB, Bax, and caspase-8 expressions and NF-κB/p65 phosphorylation but reduced BcL-2 expression in the liver. Moreover, in vitro experiments demonstrated that the pretreatment of H2O2-treated NIH/3T3 cells with KF-8 significantly mitigated the NF-κB signaling and attenuated the Nrf2 nuclear transport (both p < 0.05). In conclusion, KF-8 treatment inhibited aging-induced oxidative stress-related organ injury in mice by attenuating NF-κB/p38 signaling and preserving Nrf2 activity.

Abstract
Objective The paper intends to study the protective effects of sulforaphane (SF) on acute alcoholic hepatic injury in mice by intragastric administration of SF, aerobic exercise and the approach of SF integrated with aerobic exercise. Methodology 60 NIH mice were randomly divided into 6 groups of equal number according to their body weight and were intragastrically administrated with 50% ethanol. The serum and liver indexes of each group of mice were detected, and the liver was stained with oil red O for pathological examination. Results Compared with the model group, the serum TG and the ratio of liver to body weight of the model mice that suffered from acute alcoholic hepatic injury could be significantly decreased in the group that practiced aerobic exercise, the group administered with SF, and the group treated with the approach of SF integrated with aerobic exercise (P < 0.05). The contents of TG and MDA in liver could be significantly decreased (P < 0.05) and SOD activity could be significantly increased (P < 0.05) both in the group administered with SF and the group treated with the approach of SF integrated with aerobic exercise. Serum VLDL (P < 0.05) could also be significantly reduced in the group treated with the approach of SF integrated with aerobic exercise. Conclusion Both SF and aerobic exercise could alleviate alcohol-induced acute alcoholic hepatic injury in mice possibly thanks to the working mechanism related to antioxidant stress that reduced the harm posed by alcohol on hepatic cells. In addition, the protective effect of SF on acute alcoholic hepatic injury in mice was stronger than that of aerobic exercise, while the approach of SF integrated with aerobic exercise had the strongest protective effect on acute alcoholic hepatic injury in mice.

Abstract
UNC5A has been reported to be related with human cancers. However, the function and mechanism in non-small cell lung carcinoma (NSCLC) remains unknown. We analyzed two NSCLC cell lines (A549 and H157), one normal human bronchial epithelial cell line (BEAS-2B) and the tissues of NSCLC. We used quantitative real-time PCR (qRT-PCR), western blot and immunohistochemical (IHC) staining to examine the expression of UNC5A. Methylation status of the UNC5A promoter was analyzed using methylation-specific PCR (MSP) and bisulfite sequencing PCR (BSP). We used western blot to analyzed protein levels of PI3K/Akt pathway. We found that the mRNA expression of UNCA5 was significantly downregulated in NSCLC cells and tissues. The promoter of UNC5A was hypermethylated in NSCLC cells compared to normal control cells. The expression of UNC5A could be reversed by demethylation agent in NSCLC cells. The expression of UNC5A was decreased in NSCLC samples and significantly associated with the advanced types of NSCLC. Functionally, knockdown of UNC5A promoted cell proliferation, migration, invasion and induced apoptosis in NSCLC, overexpression of UNC5A yielded the opposite result. Moreover, we found that UNC5A negatively regulated PI3K/Akt signaling pathway in NSCLC. UNC5A is a novel epigenetically silenced gene in NSCLC and consequent under-expression of UNC5A may contribute to NSCLC tumorigenesis through regulating PI3K/Akt pathway.

Abstract
The genus Plesiastrea used to be a member of the traditional family Faviidae, falling into the challenging 'Bigmessidae' clade, and was re-established until recent molecular phylogenies published. The entire mitogenome of the symbiotic coral Plesiastrea versipora (Lamarck, 1816), the type species of the family Plesiastreidae, was sequenced. The length of the mitochondrial genome is 15,320 bp and it includes thirteen protein-coding genes (PCGs), two rRNAs and two tRNAs. The nucleotide composition of GC is 32%. We perform phylogenetic reconstruction based on maximum likelihood (ML) and Bayesian analysis(BI) using all PCGs. Our result indicates that P. versipora clusters closely with species which belong to Mussidae, Merulinidae and Lobophylliidae. Our phylogenetic analyses provide solid evidence for phylogenetic placement of P. versipora and the evolutionary relationships among different families within the traditional robust clade of Scleractinia. In addition, the mitogenome data provide useful information for further molecular systematic investigations on Plesiastreidae as well as conservation biology research of P. versipora.

Abstract
Titanium dioxide nanoparticles (TiO2-NPs) are widely used for biomedical and food applications, the toxicity of TiO2-NPs in vivo and in vitro has been elucidated, but the underlying cytotoxicity of TiO2-NPs against microRNA remains largely unknown. The purpose of this study was to analyze microRNA profiling induced by TiO2-NPs against NCM460 and HCT116 cell lines. Comparative analysis identified 34 and 24 microRNAs were significantly altered in the TiO2-NPs treated cells at concentrations of 3 μg/mL and 30 μg/mL, respectively. Functional classification demonstrated that a large proportion of genes involved in metabolism, human disease, and environmental information process were significantly upregulated by TiO2-NPs. Bioinformatics analysis suggested that microRNA 378 might be an early indicator of cellular response to exogenous stimuli with apoptotic signals. Furthermore, TiO2-NPs significantly altered the expression of microRNA 378b and 378g in HCT116 and NCM460 cell lines at different concentrations from 3 to 6 μg/mL. These concentrations elicit high-sensitivity of stimuli response in colon cancer cells when exposed to the slight doses of TiO2-NPs. Our study indicated that microRNAs 378b and 378g may play an important role in TiO2-NPs-mediated colonic cytotoxicity, which may provide a valuable insight into the molecular mechanisms of potential risks in colitis and colon cancer.

HMGN5 promotes IL-6-induced epithelial-mesenchymal transition of bladder cancer by interacting with Hsp27. Aging (Albany NY) 2020; 12:7282-7298.

Abstract
Bladder cancer (BC) is one of the most common cancers worldwide, with a high rate of recurrence and poor outcomes. High-mobility group nucleosome-binding domain 5 (HMGN5) is overexpressed in many cancers and could cause carcinogenesis in BC. By protein-protein-interaction (PPI) analysis, we found that heat shock protein 27 (Hsp27), also a crucial functional factor in BC carcinogenesis, is significantly related to HMGN5. Hsp27 is required for IL-6-mediated EMT via STAT3/Twist signaling in prostate cancer. Here, we hypothesize that HMGN5 may interact with Hsp27 to affect IL-6-induced EMT and invasion in BC via STAT3 signaling. In the present study, we found that HMGN5 and Hsp27 are highly expressed in BC tissues and positively correlated with each other. HMGN5 interacts with Hsp27 in vitro, to modulate the cell invasion and EMT in BC. Moreover, HMGN5 could modulate IL-6-Hsp27-induced EMT and invasion in BC cells by regulating STAT3 phosphorylation and STAT3 targeting of the Twist promoter. HMGN5 interacts with Hsp27 to promote tumor growth in a human BC xenograft model in nude mice. In summary, HMGN5 interacts with Hsp27 to promote IL-6-induced EMT, therefore promoting invasion in BC and contributing to the progression of BC.

Abstract
Nano Ag has excellent antibacterial properties and is widely used in various antibacterial materials, such as antibacterial medicine and medical devices, food packaging materials and antibacterial textiles. Despite the many benefits of nano-Ag, more and more research indicates that it may have potential biotoxic effects. Studies have shown that people who ingest nanoparticles by mouth have the highest uptake in the intestinal tract, and that the colon area is the most vulnerable to damage and causes the disease. In this study, we examined the toxic effects of different concentrations of Ag-NPs on normal human colon cells (NCM460) and human colon cancer cells (HCT116). As the concentration of nanoparticles increased, the activity of the two colon cells decreased and intracellular reactive oxygen species (ROS) increased. RT-qPCR and Western-blot analyses showed that Ag NPs can promote the increase in P38 protein phosphorylation levels in two colon cells and promote the expression of P53 and Bax. The analysis also showed that Ag NPs can promote the down-regulation of Bcl-2, leading to an increased Bax / Bcl-2 ratio and activation of P21, further accelerating cell death .This study showed that a low concentration of nano Ag has no obvious toxic effect on colon cells, while nano Ag with concentrations higher than 15 μg/mL will cause oxidative damage to colon cells.

Abstract
Improper nutrition provokes many types of chronic diseases and health problems, which consequently are associated with particularly high costs of treatments. Nowadays, consumer's interest in healthy eating is shifting towards specific foods or food ingredients. As a consequence, bioactive peptides as a promising source of health promoting food additives are currently an intensely debated topic in research. Process design is still on its early stages and is significantly influenced by important preliminary decisions. Thus, parameters like peptide bioactivity within the product, selection of the protein source, enzyme selection for hydrolysis, peptide enrichment method, as well as stability of the peptides within the food matrix and bioavailability are sensitive decision points, which have to be purposefully coordinated, as they are directly linked to amino acid content and structure properties of the peptides. Branched chain amino acids (BCAA) are essential components for humans, possessing various important physiologic functions within the body. Incorporated within peptide sequences, they may induce dual functions, when used as nutraceuticals in functional food, thus preserving the foodstuff and prevent several widespread diseases. Furthermore, there is evidence that consuming this peptide-class can be a nutritional support for elderly people or improve human health to prevent diseases caused by incorrect nutrition. Based on the knowledge about the role of BCAA within various peptide functions, discussed in the review, special attention is given to different approaches for systematic selection of the protein source and enzymes used in hydrolysis, as well as suitable peptide enrichment methods, thereby showing current trends in research.

Abstract
The "metabolic memory", a phenomenon that the target cell remembers the early hyperglycemia, has been reported to be a critical issue in diabetes pathogenesis. Here, we confirmed the inducible effects of high glucose (HG) and HG followed by normal glucose (HN) upon the proliferation and the tube formation capacity of human umbilical vein endothelial cells (HUVECs), as well as the suppressive effects of HG and HN on HUVEC apoptosis. In the meantime, the miR-320 expression could be dramatically downregulated (** and ## P < 0.01), whereas VEGFA expression (** and ## P < 0.01) and VEGFA, PKC, and RAGE protein levels could be remarkably induced via HG and HN stimulation. More importantly, the effects of HG and HN were not significantly different, suggesting the existence of high glucose-induced metabolic memory and the involvement of miR-320 and VEGFA in high glucose-induced metabolic memory in HUVECs. Consistently, miR-320 overexpression significantly reversed the effects of HG and HN on HUVECs (* and # P < 0.05, ** and ## P < 0.01). miR-320 suppressed the expression of VEGFA via direct binding to the 3'-UTR of VEGFA mRNA, therefore suppressing high glucose-induced metabolic memory (** P < 0.01); the effects of miR-320 overexpression on HUVECs could be reversed by VEGFA overexpression (# P < 0.05, ## P < 0.01), indicating that miR-320/VEGFA axis modulates the proliferation, apoptosis, and the angiogenesis capacity of HUVECs. In conclusion, we demonstrate that miR-320/VEGFA axis is crucial to high glucose-induced metabolic memory during HUVEC dysfunction and may be involved in the pathology of diabetes.

Amino Acid Composition, Antioxidant, and Cytoprotective Effect of Blue Mussel ( Mytilus edulis) Hydrolysate through the Inhibition of Caspase-3 Activation in Oxidative Stress-Mediated Endothelial Cell Injury. Mar Drugs 2019; 17:md17020135. [PMID: 30823522 PMCID: PMC6409750 DOI: 10.3390/md17020135] [Citation(s) in RCA: 23] [Impact Index Per Article: 4.6] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/30/2019] [Revised: 02/16/2019] [Accepted: 02/21/2019] [Indexed: 12/14/2022] Open
Abstract
Enhanced oxidative stress plays a central role in promoting endothelial dysfunction, leading to the development of atherosclerosis. In this study, we investigated the protective effects of the hydrolysates derived from blue mussel (Mytilus edulis) against H₂O₂-mediated oxidative injury in human umbilical vein endothelial cells (HUVECs). The blue mussel hydrolysates were prepared by enzymatic hydrolysis with eight proteases, and blue mussel-α-chymotrypsin hydrolysate (BMCH) showed the highest antioxidant activities in DPPH radical scavenging, ABTS⁺ radical scavenging, and ORAC value compared to those of the other hydrolysates. BMCH also inhibited Cu2+-mediated low density lipoprotein (LDL) oxidation. Treatment of H₂O₂ resulted in the decreased HUVEC viability whereas pre-treatment with BMCH increased HUVEC viability and reduced reactive oxygen species (ROS) generation. BMCH pre-treatment increased cellular antioxidant capacities, including levels of glutathione (GSH), superoxide dismutase (SOD), catalase (CAT), and glutathione peroxidase (GPx) against H₂O₂-mediated oxidative stress in HUVECs. Flow cytometry and western blot analysis revealed that BMCH pre-treatment significantly reduced H₂O₂-mediated HUVEC apoptosis through inhibition of caspase-3 activation. Real-time-qPCR analysis showed that BMCH down-regulated expression of p53 and caspase-3 genes, as well as decreased the bax/bcl-2 ratio. Taken together, these results indicate that BMCH may be useful as functional food ingredients for protecting endothelial dysfunction or related disease.

ULTRASONICS SONOCHEMISTRY 2018; 49:294-302.

Abstract
The arrowhead has attracted great research interest for their potential applications in pharmacy, food and biomedical areas. However, no information is reported about the nature and structure of the arrowhead protein (AP). Herein, effects of slit divergent ultrasound (28, 33, 40 KHz frequencies at 30-50 °C) and enzymatic (pepsin, trypsin, and alcalase) treatment on structure of AP were studied. In addition, changes in antioxidant activity of AP treated with ultrasound and enzymes were measured by chemical and cellular-based assays. The results showed that ultrasound treatment had considerable impact on the structure of AP and increased the susceptibility of AP to pepsin, trypsin and alcalase proteolysis. The changes in UV-Vis spectra, free sulfhydryl (SH) and disulfide bonds (SS) groups indicated that the structure of AP unfolded after ultrasound treatment. Besides, intrinsic fluorescence intensity of AP was increased by ultrasound treatment and then decreased after following enzymatic treatment. The circular dichroism (CD) analysis showed that ultrasound and enzymatic treatment decreased α-helix, β-turn of content of AP. However, the β-sheet and random coil content of AP increased. Interestingly, the AP after ultrasound and enzymatic treatment showed significant higher anti-oxidative activity in RAW 264.7 cells (p < 0.05) in comparison with control. In conclusion, the slit divergent ultrasonic provides a powerful endorsement for increasing the proteolysis of AP. Moreover, the improvement of the antioxidant activity of AP enzymatic hydrolysates provides a foundation of developing new type of plant-derived antioxidant peptides application.

Peptides from rice endosperm protein restrain periodontal bone loss in mouse model of periodontitis. Arch Oral Biol 2018; 98:132-139.

Abstract
OBJECTIVE Food-derived peptides have been reported to exhibit antibacterial activity against periodontal pathogenic bacteria. However, no effect has been shown on inflammation and bone resorption in periodontal pathology. The overall objective of the current study was to investigate how rice peptides influence biological defense mechanisms against periodontitis-induced inflammatory bone loss, and identify their novel functions as a potential anti-inflammatory drug. DESIGN The expression of inflammatory and osteoclast-related molecules was examined in mouse macrophage-derived RAW 264.7 cell cultures using qPCR. Subsequently, the effect of these peptides on inflammatory bone loss in mouse periodontitis was examined using a mouse model of tooth ligation. Briefly, periodontal bone loss was induced for 7 days in mice by ligating the maxillary second molar and leaving the contralateral tooth un-ligated (baseline control). The mice were microinjected daily with the peptide in the gingiva until the day before euthanization. One week after the ligation, TRAP-positive multinucleated cells (MNCs) were enumerated from five random coronal sections of the ligated sites in each mouse. RESULTS Rice peptides REP9 and REP11 significantly inhibited transcription activity of inflammatory and osteoclast-related molecules. Local treatment with the rice peptides, in mice subjected to ligature-induced periodontitis, inhibited inflammatory bone loss, explaining the decreased numbers of osteoclasts in bone tissue sections. CONCLUSION Therefore, these data suggested that the rice peptides possess a protective effect against periodontitis.

JOURNAL OF AGRICULTURAL AND FOOD CHEMISTRY 2018; 66:5178-5189.

Abstract
WDHHAPQLR (RAP) is an antioxidative peptide derived from rapeseed protein. Although the health benefits from RAP, due to its antioxidant activities, have been determined by chemical methods, a systematic assessment regarding the absorption, metabolism, and antioxidation processes of RAP is still lacking attention. Hence, Caco-2 cell monolayer models and animal experiments were used to evaluate the absorption and bioavailability of RAP. As expected, RAP could be absorbed by intestinal epithelial cells, and the Papp was 0.82 ± 0.19 × 10-6 cm/s. Three main fragments, RAP, DHHAPQLR, and WDHHAP were transported by the paracellular pathway, and QLR was transported by PepT1. An important modified product of RAP (EGDHHAPQLR) was found to contribute to the elimination of intracellular reactive oxygen species. The absolute bioavailability of RAP was 3.56%, and three degradation products of RAP were also detected in rat serum. More importantly, RAP exerts its antioxidant activity by inhibiting the apoptosis of oxidative stress cells. RAP could downregulate the expression of Bax and caspase-3 and upregulate the expression of Bcl-2 in H2O2-induced HUVECs (human umbilical vein endothelial cells). In general, using in vitro and in vivo experimental models, the in vivo absorption and transformation processes of RAP and its antioxidative molecular mechanisms by inhibiting apoptosis of cells were revealed.
