[PMID: 37742863 DOI: 10.1016/j.envpol.2023.122605] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 07/06/2023] [Revised: 09/20/2023] [Accepted: 09/21/2023] [Indexed: 09/26/2023]
Abstract
Glufosinateammonium (GLA) is one of the most widely used agricultural herbicides. It is frequently detected in surface waters near farmland and may pose a risk to non-target aquatic species. This study aimed to explore the toxicity of subacute GLA exposure in crayfish. Adult red swamp crayfish were exposed to GLA (0, 1, 10, and 100 mg/L) for 21 days. Bioaccumulation, oxidative stress, nonspecific immunity, and the expression of genes encoding xenobiotic detoxification-related enzymes were examined. The results showed GLA accumulation and hepatopancreatic histopathological changes (dilation of hepatic tubules and vacuolation of hepatocytes) in the exposed crayfish. GLA exposure induced ROS production, inhibited glutathione expression, and catalase activity in the crayfish hepatopancreas, as well as inhibited immunoenzyme expression (acid phosphatase, alkaline phosphatase, and lysozyme) in the hemolymph. In addition, the total hemocyte number decreased, and the proportion of hemocyte subsets changed significantly. Superoxide dismutase first increased and then decreased with increasing GLA dosage. GLA promoted the expression of biotransformation enzymes (cypb5, gst) in the hepatopancreas. Our results suggest that subacute GLA exposure caused structural damage to the hepatopancreatic tissue and decreased antioxidant capacity and non-specific immunity in crayfish. These findings provide insight into the toxicity of herbicides on non-target organisms.

Anti-Inflammatory and Antioxidant Properties of β-Sitosterol in Copper Sulfate-Induced Inflammation in Zebrafish ( Danio rerio). Antioxidants (Basel) 2023; 12:antiox12020391. [PMID: 36829951 PMCID: PMC9952786 DOI: 10.3390/antiox12020391] [Citation(s) in RCA: 5] [Impact Index Per Article: 5.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/17/2022] [Revised: 01/31/2023] [Accepted: 02/01/2023] [Indexed: 02/09/2023] Open
Abstract
β-Sitosterol, which is used extensively in pharmaceuticals, nutraceuticals, and cosmetics, has high nutritional value along with immunomodulatory and anti-inflammatory properties. In this study, we investigated the antioxidant and anti-inflammatory effects of β-sitosterol in zebrafish and explored the associated molecular mechanisms. In an in vivo antioxidant experiment, zebrafish (Danio rerio) larvae were treated with different concentrations of β-sitosterol and then exposed to a nonlethal concentration of CuSO4 to induce oxidative stress. Treatment with β-sitosterol at 70 or 100 μg/mL significantly reduced CuSO4-induced oxidative stress in the zebrafish, demonstrating the strong antioxidant activity of β-sitosterol. Treatment with β-sitosterol protected zebrafish larvae against oxidative damage from CuSO4 by upregulating the expressions of sod and gpx4b. In a zebrafish model of inflammation, pretreatment with β-sitosterol before CuSO4 exposure inhibited neutrophil recruitment and damage to lateral line neuromasts, indicating a potent anti-inflammatory effect derived from reductions in the expressions of il-8 and myd88. The results demonstrate the antioxidative and anti-inflammatory activities of β-sitosterol and suggest that β-sitosterol may be useful for the treatment of various inflammatory diseases.

Quercetin alleviates cyclophosphamide-induced premature ovarian insufficiency in mice by reducing mitochondrial oxidative stress and pyroptosis in granulosa cells. J Ovarian Res 2022; 15:138. [PMID: 36572950 PMCID: PMC9793602 DOI: 10.1186/s13048-022-01080-3] [Citation(s) in RCA: 14] [Impact Index Per Article: 7.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/25/2022] [Accepted: 12/16/2022] [Indexed: 12/28/2022] Open
Abstract
BACKGROUND Exposure to cyclophosphamide (CTX) induces premature ovarian insufficiency (POI). Quercetin is a natural flavonoid that exhibits anti-inflammatory and antioxidant properties, and its antioxidant activity is correlated with POI. However, the mechanism underlying its protective role in CTX-induced ovarian dysfunction is unclear. This study aimed to explore whether quercetin can protect ovarian reserves by activating mitochondrial biogenesis and inhibiting pyroptosis. METHODS Thirty-six female C57BL/6 mice were randomly subdivided into six groups. Except for the control group, all groups were injected with 90 mg/kg CTX to establish a POI model and further treated with coenzyme 10 or various doses of quercetin. The mice were sacrificed 48 h after 10 IU pregnant mare serum gonadotropin was injected four weeks after treatments. We used enzyme-linked immunosorbent assays to detect serum hormone expression and light and transmission electron microscopy to assess ovarian tissue morphology and mitochondria. Additionally, we tested oxidant and antioxidant levels in ovarian tissues and mitochondrial function in granulosa cells (GCs). The expression of mitochondrial biogenesis and pyroptosis-related proteins and mRNA was analyzed using western blotting and RT-qPCR. RESULTS Quercetin elevated serum anti-Müllerian hormone, estradiol, and progesterone levels, decreased serum follicle-stimulating hormone and luteinizing hormone levels, and alleviated ovarian pathology. It reduced the mitochondrial DNA content and mitochondrial membrane potential. Furthermore, it upregulated ATP levels and the mRNA and protein expression of peroxisome proliferator-activated receptor gamma coactivator 1-alpha (PGC1α), mitochondrial transcription factor A, and superoxide dismutase 2. In addition, it suppressed NOD-like receptor pyrin domain containing 3, caspase-1, interleukin-1β, and gasdermin D levels in the GCs of POI mice. CONCLUSIONS Quercetin protected the ovarian reserve from CTX-induced ovarian damage by reversing mitochondrial dysfunction and activating mitochondrial biogenesis via the PGC1-α pathway. Moreover, quercetin may improve ovarian functions by downregulating pyroptosis in the CTX-induced POI model. Thus, quercetin can be considered a potential agent for treating POI.

Abstract
The market demand for marine-based cosmetics has shown a tremendous growth rate in the last decade. Marine resources represent a promising source of novel bioactive compounds for new cosmetic ingredient development. However, concern about sustainability also becomes an issue that should be considered in developing cosmetic ingredients. The fisheries industry (e.g., fishing, farming, and processing) generates large amounts of leftovers containing valuable substances, which are potent sources of cosmeceutical ingredients. Several bioactive substances could be extracted from the marine by-product that can be utilized as a potent ingredient to develop cosmetics products. Those bioactive substances (e.g., collagen from fish waste and chitin from crustacean waste) could be utilized as anti-photoaging, anti-wrinkle, skin barrier, and hair care products. From this perspective, this review aims to approach the potential active ingredients derived from marine by-products for cosmetics and discuss the possible activity of those active ingredients in promoting human beauty. In addition, this review also covers the prospect and challenge of using marine by-products toward the emerging concept of sustainable blue cosmetics.

Abstract
The accumulation of diminutive plastic waste in the environment, including microplastics and nanoplastics, has threatened the health of multiple species. Nanoplastics can adsorb the pollutants from the immediate environment, and may be used as carriers for pollutants to enter organisms and bring serious ecological risk. To evaluate the toxic effects of microcystin-LR (MCLR) on the liver of adult zebrafish (Danio rerio) in the presence of 70 nm polystyrene nanoplastics (PSNPs), zebrafish were exposed to MCLR alone (0, 0.9, 4.5 and 22.5 μg/L) and a mixture of MCLR + PSNPs (100 μg/L) for three months. The results indicated that groups with combined exposure to MCLR and PSNPs further enhanced the accumulation of MCLR in the liver when compared to groups only exposed to MCLR. Cellular swelling, fat vacuolation, and cytoarchitectonic damage were observed in zebrafish livers after exposure to MCLR, and the presence of PSNPs exacerbated these adverse effects. The results of biochemical tests showed the combined effect of MCLR + PSNPs enhanced MCLR-induced hepatotoxicity, which could be attributed to the altered levels of reactive oxygen species, malondialdehyde and glutathione, and activities of catalase. The expression of genes related to antioxidant responses (p38a, p38b, ERK2, ERK3, Nrf2, HO-1, cat1, sod1, gax, JINK1, and gstr1) was further performed to study the mechanisms of MCLR combined with PSNPs aggravated oxidative stress of zebrafish. The results showed that PSNPs could improve the bioavailability of MCLR in the zebrafish liver by acting as a carrier and accelerate MCLR-induced oxidative stress by regulating the levels of corresponding enzymes and genes.

Abstract
The effects of intestinal inflammation on the brain and behavior have received a lot of attention. Melanin (MSI) from Sepiapharaonis ink as an emerging functional food, it exhibited a significant protective effect on dextran sulfate sodium (DSS) induced colitis in previous study. In present study, C57BL/6J mice were free to drink 2.5% DSS solution to establish the colitis model. During the DSS treatment, mice were orally administrated with MSI once per day (75, 150, and 300 mg/kg, respectively). The results showed that MSI treatment ameliorated the depression and anxiety symptoms of colitis mice. Further mechanism studies indicated that MSI alleviated inflammatory response by adjusting cytokines TNF-α, IL-1β, IFN-γ, and IL-10, and proteins NLRP3/ASC/caspase-1 inflammasome), inhibited the activation of microglia, restored brain synaptic density, reduced oxidative stress (SOD, MDA) and regulated apoptosis (tunel staining, caspase-3). MSI could modulate depression-anxiety states by targeting inflammation, nerve tissue, oxidative stress and apoptosis. MSI administration could serve as an emerging blue food and nutrition strategy for the prevention of digestive tract inflammation and behavioral disorders.

Abstract
Melanin is the major component from Sepiapharaonis ink (MSI), and its anti-inflammatory and antioxidant activities indicate the potential for improvement of inflammatory bowel diseases. The study aimed to investigate how orally-administered MSI on alleviating the dextran sulfate sodium (DSS)-induced ulcerative colitis (UC) and the potential mechanisms. We found that MSI significantly improved DSS-induced weight loss, colon shortening, hematochezia, DAI score, histopathology, and antioxidant indices (SOD and MDA). Further analysis demonstrated that MSI could significantly down-regulate the expression of pro-inflammatory cytokines (TNF-α, IL-1β and IFN-γ) and up-regulate the concentration of anti-inflammatory cytokine IL-10 by regulating TLR4/NF-κB and NLRP3/ASC/Caspase-1 signal pathway. Moreover, tight junction proteins in melanin groups were also maintained by ZO-1 and occludin expressions. In addition, MSI also regulated cellular apoptosis by reducing the expression of pro-apoptosis protein Caspase-3. Interestingly, MSI treatments increased the proportion of dominant bacteria (such as Bacteroidetes and Clostridium) and the abundance of community (alpha diversity, β-diversity, etc.), which significantly balanced microbiota in a dose-dependent manner. In conclusion, oral administration of MSI alleviated DSS-induced colitis by modulating inflammatory cytokines and oxidation stress, maintaining the mucosal barrier, and reverting microbiota changes.

Abstract
The effect of low concentration Cd stress on bivalves is unclear. In this study, Asian clams (Corbicula fluminea) were continuously exposed to 0, 0.05, 0.10, and 0.20 mg/L Cd for 14 d (exposure phase) and to artificial freshwater for 7 d (depuration phase). A total of 16 variables were measured to explore the toxic effects on C. fluminea. All physiological characteristics were significantly inhibited in the treatments (p < 0.05), and the negative effects of Cd did not return to normal levels in the short term. Tissue damage was found in the feet and gills of C. fluminea in all the treatments. On the 7th day (D7), enzyme activity in all the treatments was significantly higher (p < 0.05) than in the control group. Acetylcholinesterase, superoxide dismutase, and catalase activities were enhanced on D14 in all the treatments. However, only glutathione S-transferase activity was significantly higher in all the treatments (p < 0.05) than in the control group on D21. The instability of the enzymes indicated that the adaptability of C. fluminea became stronger throughout the experiment. In each group, the maximum bioaccumulation of Cd followed the order: 0.20 mg/L > 0.05 mg/L > 0.10 mg/L, which might be caused by the filtration capacity of C. fluminea in the 0.05-mg/L group, which was higher than that of the 0.10-mg/L group. Thus, low Cd concentrations effect the physiological characteristics, tissue health, and antioxidant system of C. fluminea and may require a long recovery time to be restored to normal levels.

Abstract
Intestinal mucositis is a clinically relevant side effect of anticancer therapies. It is experienced by 60–100% of patients undergoing treatment with high doses of chemotherapy, radiation therapy, and bone marrow transplantation. Intestinal mucositis can manifest as pain, weight loss, inflammation, diarrhea, rectal bleeding, and infection; affecting normal nutritional intake and intestinal function. It often impacts adherence to anticancer therapy as it frequently limits patient’s ability to tolerate treatment, causing schedule delays, interruptions, or premature discontinuation. In some cases, local and systemic secondary infections are observed, increasing the costs toward medical care and hospitalization. Several strategies for managing mucositis are available which do not always halt this condition. In this context, new therapeutic strategies are under investigation to prevent or treat intestinal mucositis. Polysaccharides from natural resources have recently become promising molecules against intestinal damage due to their ability to promote mucosal healing and their anti-inflammatory actions. These effects are associated with the protection of intestinal mucosa and regulation of microbiota and immune system. This review aims to discuss the recent advances of polysaccharides from natural resources as potential therapies for intestinal mucositis. The source, species, doses, treatment schedules, and mechanisms of action of polysaccharides will be discussed in detail.

Abstract
Underutilized marine food products such as cephalopods' ink could be sources of bioactive compounds providing health benefits. This study aimed to assess the anti-proliferative and anti-inflammatory effects from Octopus vulgaris ink extracts (hexane-, ethyl acetate-, dichloromethane- (DM), and water extracts) using human colorectal (HT-29/HCT116) and breast (MDA-MB-231) cancer cells, and LPS-challenged murine RAW 264.7 cells. Except by ethyl-acetate, all of the extracts exhibited anti-proliferative effects without being cytotoxic to ARPE-19 and RAW 264.7 cells. Among DM fractions (F1/F2/F3), DM-F2 showed the highest anti-proliferative effect (LC50 = 52.64 μg/mL), inducing pro-apoptotic morphological disruptions in HCT116 cells. On RAW 264.7 cells, DM-F2 displayed the lowest nitrites reduction and up-regulation of key-cytokines from the JAK-STAT, PI3K-Akt, and IL-17 pathways. Compared to control, DM-F2 increased IL-4 and decreased NF-κB fluorometric expression in peripheral blood mononuclear cells (PBMCs). Metabolomic analysis of DM-F2 highlighted hexadecanoic acid and 1-(15-methyl-1-oxohexadecyl)-pyrrolidine as the most important metabolites. These compounds also exhibited high in silico binding affinity (-4.6 to -5.8 kcal/mol) to IL-1α, IL-1β, and IL-2. Results suggested the joint immuno-modulatory and anti-proliferative effect derived from selected compounds of underutilized marine food products such as ink. This is the first report of such biological activities in extracts from O. vulgaris ink.

Abstract
Melanin is a pigment contains in human skin which role as a UV-absorbing agent. One of the exogenous melanins can be obtained from squid (Loligo sp.) ink. Squid ink melanin has potent free radical protection activities. This study aimed to determine the physicochemical, stability, antioxidant, and UV protection activities of squid ink powder lotions. Squid ink powders were obtained from the drying process using HCl 0.5M and stored in the climatic chamber. Antioxidant activity was conducted quantitatively using the DPPH (2,2-diphenyl-1-picrylhydrazil) scavenging method. The best result of the DPPH scavenging activity was 29.12±0.023%, shown from formula III. UV protection activity was conducted by observing erythema scores in animal skin, which exposure to UV. This preparation inhibits the effect of UV exposure. Squid ink powder lotions are potential as a sunscreen product.

Ding Y, Yu J, Guo Q, Gao B, Huang J. Molecular characterization of two Chinese pedigrees with maternally inherited hypertension. J Gene Med 2021; 23:e3328. [PMID: 33625761 DOI: 10.1002/jgm.3328] [Citation(s) in RCA: 6] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/14/2020] [Revised: 02/06/2021] [Accepted: 02/19/2021] [Indexed: 11/06/2022] Open
Abstract
BACKGROUND Mutations in mitochondrial tRNA (mt-tRNA) genes are associated with hypertension, although their pathogenic mechanisms remain poorly understood. METHODS In the present study, two Han Chinese families with maternally transmitted hypertension were interviewed. The mtDNA mutations of matrilineal relatives were screened by polymerase chain reaction-Sanger sequencing. Mitochondrial ATP, membrane potential and reactive oxygen species (ROS) were also analyzed in polymononuclear leukocytes carrying these mt-tRNA mutations. Additionally, the levels of oxidative stress-related biomarkers [malondialdehyde (MDA), superoxide dismutase (SOD) and glutathione peroxidase (GSH-Px) and 8-hydroxy-2-deoxyguanosine (8-OHdG)] were analyzed. RESULTS Nine of 13 adult matrilineal relatives of these pedigrees exhibited a wide range of severity of hypertension. The age at onset of hypertension was 30-62 years (average 46 years). Mutational screening of mitochondrial genomes revealed tRNAArg T10410C and T10454C mutations. Indeed, the m.T10454C and m.T10410C mutations occurred at conserved bases of TΨC-loop and acceptor arm of tRNAArg (positions 55 and 6), which are critical for tRNAArg post-transcriptional modification. Thus, the defects in tRNA modification may cause failure in tRNA metabolism, impairing mitochondrial translation. Biochemical analysis revealed that m.T10454C or m.T10410C mutation significantly reduced mitochondrial ATP and membrane potential and also increased ROS production in mutant cell lines (all p < 0.05). In addition, the levels of MDA and 8-OHdG in hypertensive patients markedly increased, whereas those of SOD and GSH-Px decreased (all p < 0.05). CONCLUSIONS These findings demonstrate that m.T10410C and m.T10454C mutations affect the structure and function of tRNAArg and consequently alter mitochondrial function and lead to oxidative stress, which are involved in the pathogenesis of maternally inherited hypertension.

Neutrophils Enhance Cutaneous Vascular Dilation and Permeability to Aggravate Psoriasis by Releasing Matrix Metallopeptidase 9. J Invest Dermatol 2020; 141:787-799.

Abstract
Neutrophil infiltration and papillary vessel dilation are hallmarks of the initiation phase of psoriatic lesions. However, how neutrophils aggravate psoriasis development during transendothelial migration and the interaction between neutrophils and cutaneous vascular endothelial cells are less well-understood. In this study, we reported that neutrophils and cutaneous vascular endothelial cells activated each other when neutrophils migrated through the cutaneous endothelial barrier. In addition, neutrophil infiltration into skin lesions caused vascular remodeling including cutaneous vasodilation and enhanced vascular permeability in vivo and in vitro. Microarray gene profile data showed that matrix metallopeptidase (MMP)-9 was overexpressed in psoriatic neutrophils, and zymography assay further validated the bioactivity of MMP-9 secreted by psoriatic neutrophils. Moreover, MMP-9 activated vascular endothelial cells through the extracellular signal‒regulated kinase 1/2 and p38-MAPK signaling pathways, enhancing CD4+ T-cell transmigration in vitro. Correspondingly, an MMP-9 inhibitor significantly reduced cutaneous vasodilation, vascular permeability, and psoriatic symptoms in an imiquimod- or IL-23‒induced psoriasiform mouse model. Overall, our study demonstrates that neutrophil-derived MMP-9 induces cutaneous vasodilation and hyperpermeability by activating cutaneous vascular endothelial cells, thus facilitating psoriatic lesion development, which increases our knowledge on the role of neutrophils in the pathogenesis of psoriasis.
