Abstract
Tricothecenes-2 toxin (T-2) is a major mycotoxin that is widely distributed in aquatic feeds and poses a huge challenge to the aquatic industry, but there is scant information on the toxicokinetics of T-2 in aquatic animals. Here, we describe the development of a three-compartment toxicokinetic model for the absorption, distribution, metabolism and elimination (ADME) of T-2 in shrimp. The three compartments were central (the hemolymph), slow metabolizing and fast metabolizing compartments to account for the varying ADME rates of T-2 in different shrimp organs. The toxicokinetic model was solved by the blindfold particle swarm optimization algorithm, and the values for the model equation parameters were obtained by applying the experimental data of T-2 concentrations in shrimp. The model had a good fit with the experimental data. It was revealed through the model that after i.m. administration, T-2 was rapidly absorbed into the hemolymph and distributed into shrimp organs. The hepatopancreas and intestine belonged to the fast and muscle to the slow metabolizing compartments, respectively, while the hemolymph had no capacity to metabolize T-2. The T-2 elimination rates in the hepatopancreas and intestine were similar and quite high while that in the muscle was very low. The methods used in developing and solving the model could be used for similar toxicokinetic and pharmacokinetic studies of other animals.

Abstract
To explore the protective mechanism of L-arginine against T-2 toxin-induced apoptosis in mouse Leydig cells, we investigated whether L-arginine can prevent T-2 toxin-induced apoptosis in mouse Leydig cells and explored the underlying mechanisms. Leydig cells were isolated and cultured with control, T-2 toxin (10 nM), L-arginine (0.25, 0.5, and 1.0 mM), and T-2 toxin (10 nM T-2 toxin) + L-arginine (0.25, 0.5, or 1.0 mM) for 24 h. Cells and supernatants were harvested to examine proliferation of the cells, the apoptosis rate, activity of caspase-3 and mitochondria, and the gene expression levels of Bcl-2, Bax, PARP, and caspase-3. Results showed that proliferation and mitochondrial activity of Leydig cells were inhibited by administration of T-2 toxin. Bcl-2 gene expression levels was decreased, while the gene expression levels of Bax and PARP were increased, which could trigger mitochondria-mediated apoptosis, activate downstream caspase-3, and then increased caspase-3 at both activity and gene expression levels. The expression of the Bcl-2 gene was upregulated and the expression of Bax, caspase-3, and PARP gene were downregulated when L-arginine was added to the cultured cells. The results of this study showed that L-arginine could block T-2 toxin-induced apoptosis in mouse Leydig cells by regulating specific intracellular death-related pathways.

Abstract
T‑2 toxin is a type A trichothecene mycotoxin. In order to reduce the side effects of T‑2 toxin and increase the tumor targeting ability, a pH‑sensitive liposome of T‑2 toxin (LP‑pHS‑T2) was prepared and characterized in the present study. The cytotoxicity of LP‑pHS‑T2 on A549, Hep‑G2, MKN‑45, K562 and L929 cell lines was tested by 3‑(4,5‑dimethylthiazolyl‑2)‑2,5‑diphenyltetrazolium bromide assay, with T‑2 toxin as the control. The apoptotic and migratory effects of LP‑pHS‑T2 on Hep‑G2 cells were investigated. The preparation process of LP‑pHS‑T2 involved the following parameters: Dipalmitoyl phosphatidylcholine: dioleoylphosphatidylethanolamine, 1:2; total phospholipid concentration, 20 mg/ml; phospholipid:cholesterol, 3:1; 4‑(2‑hydroxyethyl)‑1‑piperazineethanesulfonic acid buffer (pH 7.4), 10 ml; drug:lipid ratio, 2:1; followed by ultrasound for 10 min and extrusion. The encapsulation efficiency reached 95±2.43%. The average particle size of LP‑pHS‑T2 after extrusion was 100 nm; transmission electron microscopy showed that the shape of LP‑pHS‑T2 was round or oval and of uniform size. The release profile demonstrated a two‑phase downward trend, with fast leakage of T‑2 toxin in the first 6 h (~20% released), followed by sustained release up to 48 h (~46% released). From 48‑72 h, the leakage rate increased (~76% released), until reaching a minimum at 72 h. When LP‑pHS‑T2 was immersed in 0.2 mol/l disodium phosphate‑sodium dihydrogen phosphate buffers (pH 6.5), the release speed was significantly increased and the release rate reached 91.2%, demonstrating strong pH sensitivity. Overall, antitumor tests showed that LP‑pHS‑T2 could promote the apoptosis and inhibit the migration of Hep‑G2 cells. The present study provided a new approach for the development of T‑2 toxin‑based anti‑cancer drugs.

Abstract
The determination of mycotoxins content in food is not sufficient for the prediction of their potential in vivo cytotoxicity because it does not reflect their bioavailability and mutual interactions within complex matrices, which may significantly alter the toxic effects. Moreover, many mycotoxins undergo biotransformation and metabolization during the intestinal absorption process. Biotransformation is predominantly the conversion of mycotoxins meditated by cytochrome P450 and other enzymes. This should transform the toxins to nontoxic metabolites but it may possibly result in unexpectedly high toxicity. Therefore, the verification of biotransformation and bioavailability provides valuable information to correctly interpret occurrence data and biomonitoring results. Among all of the methods available, the in vitro models using monolayer formed by epithelial cells from the human colon (Caco-2 cell) have been extensively used for evaluating the permeability, bioavailability, intestinal transport, and metabolism of toxic and biologically active compounds. Here, the strengths and limitations of both in vivo and in vitro techniques used to determine bioavailability are reviewed, along with current detailed data about biotransformation of mycotoxins. Furthermore, the molecular mechanism of mycotoxin effects is also discussed regarding the disorder of intestinal barrier integrity induced by mycotoxins.

Abstract
The T-2 toxin is a trichothecene mycotoxin and is highly toxic to aquatic animals, but little is known on its toxic effect in crustaceans. In the present study, the crab juveniles were fed with diets containing four levels of T-2 toxin: 0 (control), 0.6 (T1), 2.5 (T2) and 5.0 (T3) mg/kg diet for 56 days to evaluate its impact on the juvenile of Chinese mitten crab (Eriocheir sinensis). The crabs fed the T-2 toxin diets had significantly lower weight gain and specific growth rate than those fed the control diet. Moreover, crab survival in T3 group was obviously lower than that in the control. Oxidative stress occurred in all the treatment groups as indicated by higher activities of total superoxide dismutase, glutathione peroxidase, and total antioxidant capacity than those in the control. The total hemocyte count, respiratory burst, phenoloxidase in the hemolymph, and phenoloxidase, acid phosphatase and alkaline phosphatase in the hepatopancreas of crabs fed T-2 toxin were significantly lower than those in the control. The transcriptional expressions of lipopolysaccharide-induced TNF-alpha factor, relish, and the apoptosis genes in the hepatopancreas were induced by dietary T-2 toxin. The genes related to detoxication including cytochrome P450 gene superfamily and glutathione S transferase were induced in low concentration, then decreased in high concentration. Dietary T-2 toxin damaged the hepatopancreas structure, especially as seen in the detached basal membrane of hepatopancreatic tubules. This study indicates that dietary T-2 toxin can reduce growth performance, deteriorate health status and cause hepatopancreas dysfunction in crabs.

Abstract
BACKGROUND T-2 toxin (T-2) is a potent mycotoxin and a common contaminant of aquatic animal feed, posing a serious risk to health and aquatic animals. We investigated the effect of T-2 on shrimp muscle proteins using proteomics and conventional biochemical methods. Shrimp were fed a diet containing T-2 at 0-12.2 mg kg-1 for 20 days, and changes to the muscle protein composition, ATPase activities, and the sulfhydryl (SH) content and hydrophobicity of actomyosin (AM) were determined. A proteomics study of the proteins was conducted with sodium dodecyl sulfate polyacrylamide gel electrophoresis (SDS-PAGE), two-dimensional (2D) electrophoresis, and matrix-assisted laser desorption/ionization - time of flight mass spectrometry (MALDI-TOF/TOF MS). RESULTS Exposure to T-2 markedly affected the muscle protein composition of shrimp in a concentration-responsive manner that displayed a diphasic effect. At a low T-2 concentration (1.2 mg kg-1 ), the levels of three major muscle proteins (myofibrillar, sarcoplasmic, and stroma) increased but at higher concentrations they declined progressively. T-2 exposure also led to a breakdown of muscle proteins as evidenced by increases in alkali-soluble protein and the surface hydrophobicity (SoANS) of AM. Thirty differentially expressed proteins were detected, 12 of which showed a concentration-response relationship with T-2 exposure. Among them, 11 homologous proteins were identified by mass spectrometry (MS), with several being key enzymes in energy metabolism. CONCLUSION This study demonstrated that T-2 exposure at medium to high concentrations could significantly affect the protein composition and quality of shrimp muscle, and potentially some of its key metabolisms. One of the arginine kinases (spot 27) was particularly responsive to T-2 and could potentially be used as a biomarker protein for T-2 intoxication by shrimp. © 2019 Society of Chemical Industry.

Abstract
T-2 toxin (T-2), a naturally occurring mycotoxin that often accumulates in aquatic animals via contaminated feed, is toxic to animals, including humans. In this study, six groups of shrimp (n = 30 shrimps/group) were given T-2 in feed at concentrations of 0–12.2 mg/kg for 20 days. T-2 accumulation, intestinal histopathology, digestive enzyme activities and subsequent effects on shrimp are reported. Compared to the control, T-2 significantly reduced weight gain, specific growth rate, and survival. The histopathology of shrimp intestine showed concentration-dependent degenerative and necrotic changes in response to dietary T-2. Progressive damage to the microstructures of shrimp intestine occurred with increasing dietary T-2 concentrations, with initial inflammation of the mucosal tissue at T-2 concentrations of 0.5 and 1.2 mg/kg, progressing to disappearance of intestinal villi and degeneration and necrosis of the submucosa at 12.2 mg/kg. Intestinal amylase and protease activities increased at low T-2 concentrations but showed significant inhibition at high concentrations; however, the opposite trend occurred for lipase activity. Collectively, these results indicate that digestive enzyme activities and mucosal structures are markedly affected by exposure to T-2, and these may have contributed to the lower survival rate of shrimp.

Abstract
T-2 toxin is a type-A trichothecene produced by Fusarium found in several food commodities worldwide. T-2 toxin causes reproductive disorders, genotoxicity, and testicular toxicity in animals. Our previous research has reported that T-2 toxin can induce apoptosis via the Bax-dependent caspase-3 activation in mouse primary Leydig cells. However, little is known about the functions of autophagy and the cross talk between autophagy and apoptosis after exposure to T-2 toxin in Leydig cells. This study investigated these problems in mouse primary Leydig cells. Results showed that T-2 toxin treatment upregulated LC3-II and Beclin-1 expression, suggesting that T-2 toxin induced a high level of autophagy. Pretreatment with chloroquine (an autophagy inhibitor) and rapamycin (an autophagy inducer) increased and decreased the rate of apoptosis, respectively, in contrast to T-2 toxin-treated group. Autophagy delayed apoptosis in the T-2 toxin-treated Leydig cells. Therefore, autophagy may prevent cells from undergoing apoptosis by reducing T-2 toxin-induced cytotoxicity.

Abstract
T-2 toxin (T-2), one of the naturally occurring mycotoxins, often accumulates in aquatic animals from contaminated feed. Shrimp (n = 30 per group) were fed with different concentrations (0, 0.5, 1.5, 4.5 and 13.5 mg kg-1) of T-2 for 20 days. Changes in histopathology, fatty acid and water distribution of shrimp muscle were analyzed. Histopathology of shrimp muscle showed dose-dependent marked degenerative and necrotic changes on exposure to dietary T-2. The T-2 significantly (P < 0.05) affected the muscle fatty acid composition. ∑SFA, ∑MUFA and ∑PUFA initially decreased and then increased slowly in the high-dosed groups. C16:0, C18:1n-9 and C18:2n-6 were the main saturated fatty acid (SFA), monounsaturated fatty acid (MUFA) and polyunsaturated fatty acid (PUFA), respectively. Also, T-2 significantly affected water distribution in shrimp muscle. High doses of T-2 reduced free water content, resulting in a reduction in the water holding capacity and hence changes to the shrimp muscle quality. Collectively, these results illustrated that T-2 significantly affects the fatty acid and water distribution, and also muscle histopathology, all of which would result in a reduction in the quality and nutritional value of shrimp.

[PMID: 30590246 DOI: 10.1016/j.theriogenology.2018.12.024] [Citation(s) in RCA: 14] [Impact Index Per Article: 2.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/02/2018] [Revised: 12/11/2018] [Accepted: 12/13/2018] [Indexed: 11/15/2022]
Abstract
l-arginine is beneficial for reproductive health; however, whether l-arginine may confer protection against T-2 toxin-induced reproductive impairment is not known. To address this, we used a mice model treated with T-2 toxin to investigate protective effects of l-arginine. Experimentally, we pre-treated mice with designed diet of l-arginine supplementation prior to the T-2 toxin-injected intraperitoneally exposure and then assessed semen quality, fertility and serum testosterone concentration. The results showed that l-arginine improved semen quality (e.g., live spermatozoa, abnormal spermatozoa, and acrosomal integrity of spermatozoa), testicular and cauda epididymal sperm counts, efficiency of sperm production and serum testosterone concentration in mice treated with T-2 toxin. In addition, l-arginine could increase pregnancy rate and decrease fetal resorption rate in females mated with T-2 toxin exposed males. Collectively, these findings suggest that dietary l-arginine supplementation may protect male reproductive impairments in mice treated with T-2 toxin through improving semen quality and serum testosterone levels.
