Differential susceptibility of BRL cells with/without insulin resistance and the role of endoplasmic reticulum stress signaling pathway in response to acrylamide-exposure toxicity effects in vitro. Toxicology 2024; 504:153800. [PMID: 38604440 DOI: 10.1016/j.tox.2024.153800] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/13/2023] [Revised: 03/30/2024] [Accepted: 04/08/2024] [Indexed: 04/13/2024]
Abstract
Acrylamide (ACR) is an endogenous food contaminant, high levels of ACR have been detected in a large number of foods, causing widespread concern. Since different organism states respond differently to the toxic effects of pollutants, this study establishes an insulin-resistant BRL cell model to explore the differential susceptibility of BRL cells with/without insulin resistance in response to acrylamide-exposure (0.0002, 0.02, or 1 mM) toxicity effects and its mechanism. The results showed that ACR exposure decreased glucose uptake and increased intracellular lipid levels by promoting the expression of fatty acid synthesis, transport, and gluconeogenesis genes and inhibiting the expression of fatty acid metabolism genes, thereby further exacerbating disorders of gluconeogenesis and lipid metabolism in insulin-resistant BRL cells. Simultaneously, its exposure also exacerbated BRL cells with/without insulin-resistant damage. Meanwhile, insulin resistance significantly raised susceptibility to BRL cell response to ACR-induced toxicity. Furthermore, ACR exposure further activated the endoplasmic reticulum stress (ERS) signaling pathway (promoting phosphorylation of PERK, eIF-2α, and IRE-1α) and the apoptosis signaling pathway (activating Caspase-3 and increasing the Bax/Bcl-2 ratio) in BRL cells with insulin-resistant, which were also attenuated after ROS scavenging or ERS signaling pathway blockade. Overall results suggested that ACR evokes a severer toxicity effect on BRL cells with insulin resistance through the overactivation of the ERS signaling pathway.

Takeda K, Saito T, Sasaki S, Eguchi A, Sugiyama M, Eto S, Suzuki K, Kamata R. Toxicity Assessment of Mixed Exposure of Nine Perfluoroalkyl Substances at Concentrations Relevant to Daily Intake. TOXICS 2024; 12:52. [PMID: 38251008 PMCID: PMC10819949 DOI: 10.3390/toxics12010052] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Subscribe] [Scholar Register] [Received: 11/08/2023] [Revised: 12/27/2023] [Accepted: 01/08/2024] [Indexed: 01/23/2024]
Abstract
Per- and poly-fluoroalkyl substances (PFAS) exhibit high persistence in the environment and accumulate within the human body, warranting a thorough assessment of their toxicity. In this study, we exposed mice (male C57BL/6J mice aged 8 weeks) to a composite of nine PFAS, encompassing both long-chain PFAS (e.g., perfluorooctanoic acid and perfluorooctanesulfonic acid) and short-chain PFAS (e.g., perfluorobutanoic acid and perfluorobutanesulfonic acid). The exposure concentrations of PFAS were equivalent to the estimated daily human intake in the composition reported (1 µg/L (sum of the nine compounds), representing the maximum reported exposure concentration). Histological examination revealed hepatocyte vacuolization and irregular hepatocyte cord arrangement, indicating that exposure to low levels of the PFAS mixture causes morphological changes in liver tissues. Transcriptome analysis revealed that PFAS exposure mainly altered a group of genes related to metabolism and chemical carcinogenesis. Machine learning analysis of the liver metabolome showed a typical concentration-independent alteration upon PFAS exposure, with the annotation of substances such as glutathione and 5-aminovaleric acid. This study demonstrates that daily exposure to PFAS leads to morphological changes in liver tissues and alters the expression of metabolism- and cancer-related genes as well as phospholipid metabolism.

Abstract
BACKGROUND Acrylamide is a toxic substance used in industrial and laboratory processes. Acrylamide exposure has a toxic effect on many systems. Protective mechanisms should be developed against the effects caused by acrylamide. OBJECTIVE In our study, we investigated whether exercise has a protective effect against the changes that acrylamide will cause in pancreas. METHODS 32 adult Sprague-Dawley male rats were used. Control group was given only saline. Exercise group was applied swimming exercise for 1hour daily for 4 weeks. Acrylamide group was given 50mg/kg acrylamide by gavage for 4 weeks. Acrylamide+exercise group was applied 50mg/kg acrylamide for 4 weeks and swimming exercise for 1hour daily. After the experiment, fasting blood glucose and oral glucose tolerance test measurements were performed. Then, blood and pancreas samples were taken. RESULTS Acrylamide exposure caused an increase in fasting blood glucose and oral glucose tolerance, a decrease in insulin levels and oxidative stress in acrylamide group. In exercise group, these values were similar to control group and no significant change was observed in acrylamide+exercise group. While there was an increase in the number of alpha cells in acrylamide group compared to the other groups, here was a decrease in the number of beta cells compared to control group. CONCLUSION We can say that acrylamide causes changes in the islets of Langerhans by affecting alpha and beta cell numbers. The protective effect of exercise on beta and alpha cell mass was not statistically significant in the acrylamide+exercise group. When the results were examined, the decrease in oxidative stress and the higher number of beta and alpha cells in the acrylamide+exercise group compared to the acrylamide group suggested that 4 weeks of swimming exercise may have an effect on acrylamide exposure.

Abstract
Acrylamide is used for industrial and laboratory purposes; it also is produced during cooking of carbohydrate-rich food at high temperature. We investigated the therapeutic potential of quercetin for treatment of acute acrylamide induced injury to the spleen. We used female albino rats treated with acrylamide for 10 days followed by oral administration of quercetin in three doses for 5 days. We observed significantly reduced total body weight, spleen weight, red blood cells, total proteins, superoxide dismutase, catalase, glutathione peroxidase, glutathione reductase, glucose-6-phophate dehydrogenase, reduced glutathione, concentration of serum IgG and IgM after acrylamide induced toxicity compared to controls. We also found that white blood cells, triglycerides, cholesterol and lipid oxidation were increased significantly after acrylamide induced toxicity in rats compared to controls. Histoarchitecture of spleen was affected adversely by acrylamide toxicity. Administration of quercetin ameliorated adverse effects of acrylamide in a dose-dependent manner. Quercetin appears to ameliorate acrylamide induced injury to the spleen by increasing endogenous antioxidants and improving histoarchitecture and immune function.

Abstract
SIGNIFICANCE Acrylamide (AA) widely exists in the environment. Studies have demonstrated that AA has neurotoxicity and potential carcinogenicity in humans, and genotoxicity and severe hepatotoxicity in animals. As the critical metabolism organ for AA, the liver is the primary attacking target of AA. This review summarizes the recent advances in hepatotoxicity mechanism through AA-induced oxidative stress in rodent livers and hepatic cell lines, this is beneficial to assess risks of AA exposure and explore effective intervention methods for AA hepatotoxicity. RECENT ADVANCES Accumulating evidences have indicated that AA-induced oxidative stress is responsible for its hepatotoxicity. The changes in homological and biochemical indexes such as activities of hepatic antioxidant enzymes have been elucidated with the occurrence and development of oxidative stress. Also, the molecular mechanisms underlying AA-induced hepatotoxicity through oxidative stress have been mainly explained by apoptosis, inflammatory and autophagic pathways. CRITICAL ISSUES This review is focusing on the molecular mechanism of hepatotoxicity through AA-induced oxidative stress, this can provide a theoretical basis for the assessment of AA-induced health risk and finding potential intervention targets. FUTURE DIRECTIONS Epigenetic modifications like miRNAs and modulation of the gut microbiome involved in AA toxification pathway must be investigated, and will provide novel insights to unravel the toxification mechanism and intervention strategy for AA hepatotoxicity.

Abstract
Diabetes mellitus is a common endocrine metabolic disorder, and previous studies have shown that diabetics are more sensitive to the toxic environmental contaminants. Acrylamide (ACR) is both an industrially multipurpose compound and a common endogenous food contaminant to which people are frequently exposed and at high risk. However, the toxicity of ACR on diabetes hasn't attracted much attention. In this study, both healthy mice and diabetic mice received ACR administration orally to investigate the ACR-induced metabolic toxicity, mechanism and susceptibility to ACR toxicity in adult diabetic male mice. The results showed that ACR significantly increased FBG level and decreased bodyweight, serum lipid and liver lipid biomarkers (TC, TG, LDL-C, HDL-C) levels as well as expression of lipid and glucose metabolism-related genes in diabetic mice, indicating that ACR can exacerbate metabolic disorders of glucose and lipid in diabetic male mice. Moreover, ACR exposure significantly increased levels of MDA and COX-2), decreased GSH level and antioxidant enzyme activity (SOD, GSH-PX and CAT) by downregulating expression of Nrf2 and Keap1 in diabetic mice. Factorial analysis showed ACR had a more significant disturbance in diabetic mice compared with healthy mice. Our results indicated that ACR exposure can cause oxidative stress and inflammatory damage, which can exacerbate abnormal glucose and lipid metabolism. This work helps to elucidate the effects and underlying mechanisms of ACR-induced metabolic toxicity in adults with diabetes.

The combination of T-2 toxin and acrylamide synergistically induces hepatotoxicity and nephrotoxicity via the activation of oxidative stress and the mitochondrial pathway. Toxicon 2020; 189:65-72. [PMID: 33227324 DOI: 10.1016/j.toxicon.2020.11.007] [Citation(s) in RCA: 9] [Impact Index Per Article: 2.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/26/2020] [Revised: 11/07/2020] [Accepted: 11/15/2020] [Indexed: 11/22/2022]
Abstract
T-2 toxin is a common fungal toxin, which is not only widely found in wheat, barley, corn, and other food crops and their related products, but also in various animal feeds. Acrylamide (ACR) is mainly formed by the free amino acid, asparagine and reducing sugars, such as glucose and fructose, and is commonly found in potato chips, French fries, toast, coffee, and other foods. Therefore, people are highly likely to consume food via their daily diets that are contaminated with both T-2 toxin and ACR. Since liver and kidneys were possible toxic targets of both T-2 toxin and ACR, this study assessed whether combined exposure could increase hepatotoxicity and nephrotoxicity using both cell cultures and animal models. We used L02 and MARC-145 cells and treated with T-2 toxin (5-15 nM) and ACR (1-3 mM) alone or in combination with a fixed ratio of 1:200 (T-2 toxin/ACR). ACR (50 mg/kg, i.g., 5d) and T-2 toxin (5 mg/kg, i.g., 5d) were used to assess the biochemical, proteins and histplogical changes in C57BL/6N mice. Results showed the combination resulted in synergistic cytotoxicity in vitro, while significantly increasing liver and kidney toxicity in vivo. Mechanistically, T-2 toxin decreased Manganese superoxide dismutase expression, while ACR reduced catalase expression. These two mechanisms were converged in response to the combination, leading to enhanced oxidative stress generation. The findings highlighted the necessity to consider the combined toxicity during the safety assessment of these food-borne contaminants.

Abstract
Background:
A
c
rylamide (AA) in food is a public health concern that has attracted scientists’ attention worldwide.
Objective:
This study was carried out to investigate the efficiency of
Moringa oleifera (M. olifera)
leaves in the reduction of AA in French fries in vitro and its hepato-protective properties against AA-induced liver toxicity in vivo.
Materials and Methods:
Total phenolic, flavonoid, tannin contents and antioxidant potential of
M. oleifera
leaves were evaluated and the phenolic constituents characterized via HPLC. AA content was also monitored in French fries using LC-MS/MS. For in vivo assay, mice were treated with AA alone or in combination with
M. oleifera
(150 and 250 mg/kg IP).
Results:
Phytochemical screening showed that gallic acid, ellagic acid, epicatechin, and quercetin were the most abundant phenolic compounds identified. This work also demonstrated a nearly 37% reduction in AA when French fries were soaked in 1% M. oleifera. Moreover, AA-intoxicated mice resulted in a significant (P < 0.05) elevation in the liver enzyme alanine aminotransferase (ALT), which was restored when pre-treated with M. oleifera.
Conclusion:
This study proved that M. olifera could be effective in reducing AA levels in French fries and that treatment with M. oleifera extract can restore the hepatic damage in AA-intoxicated mice.

Abstract
Cyclophosphamide (CP) is a widely used anticancer and immunosuppressant drug. Nevertheless, clinical utilization of CP is limited due to considerable adverse effects and toxicities. Nicotinamide (NMD) is a micronutrient and the effect of NMD against CP-induced hepatotoxicity is yet unexplored. The present study was designed to evaluate the chemoprotective effect of NMD against CP-induced hepatic injury in Sprague-Dawley rats. Hepatotoxicity was induced by the administration of CP (30 mg/kg/day) for 10 consecutive days by intraperitoneal injection. The chemoprotective effect of NMD treatment (200 mg/kg) against CP-induced hepatotoxicity was evaluated by the oxidative stress, liver function, histopathological changes, and DNA damage. NMD cotreatment significantly reduced CP-induced oxidative stress, histological changes, and apoptosis in the liver. The present study demonstrated that NMD treatment ameliorated CP-induced hepatic damage by improving the antioxidant system and reducing DNA damage. The present findings revealed that NMD supplementation might be useful to reduce CP-associated hepatotoxicity, and thereby can increase the therapeutic utility of CP.

Abstract
The current investigation was accomplished to evaluate the hepatoprotective effect of White tea and Raspberry Ketone against toxicity induced by acrylamide in rats. Sixty adult male rats were divided randomly into group (I) control; group (II) rats received RK with dose (6 mg/kg/day); Group III: rats received 5 ml of WT extract/kg/day; Group IV rats received AA (5 mg/kg/day); Group V: rats administrated with both AA (5 mg/kg/day) and RK (6 mg/kg/day) and Group VI: rats administrated AA (5 mg/kg/day) and 5 ml of WT extract/kg/day. The biochemical assays exhibited a significant increase in serum levels of Adiponectin, AST, ALT, ALP of the group treated with acrylamide if compared to the control group and an improvement in their levels of groups V and VI. The histopathological and immunohistochemical findings confirm the biochemical observations. In conclusion, the present investigation proved that the supplementation of WT and RK enhanced the liver histology, immunohistochemistry and biochemistry against the oxidative stress induced by acrylamide.

Abstract
As a chemical extensively used in industrial areas and formed during heating of carbohydrate-rich foods and tobacco, acrylamide (ACR) has been demonstrated to exert a variety of systemic toxic effects including hepatotoxicity and nephrotoxicity. In the present study, we investigated the effect of curcumin, a natural polyphenolic compound in a popular spice known as turmeric, on the hepatic and renal impairment caused by ACR exposure to 40 mg/kg for 4 weeks in rats. The administration of curcumin at doses of 50 and 100 mg/kg to ACR-intoxicated rats significantly decreased the serum levels of alanine transaminase, aspartate transaminase, creatinine, and urea; improved the histological changes of liver and kidney caused by ACR; reduced the number of apoptotic cells; as well as relieved ACR-induced hepatic and renal oxidative stress. Moreover, curcumin inhibited the CYP2E1 overexpression induced by ACR in the liver and kidney tissues. Therefore, curcumin could be applied as a potential strategy for the intervention of ACR-induced systemic toxicity. The inhibition of CYP2E1 might be involved in the protection of curcumin against ACR-induced hepatotoxicity and nephrotoxicity.

Abstract
Acrylamide (AA) is a toxic substance, used to synthesize polymers for industrial and laboratory processes. Also, AA is a food contaminant formed during the high temperature preparation of carbohydrate-rich food. The main subject of this study was to examine effects of subchronic AA treatment on the islets of Langerhans of adult rats. Adult male Wistar rats were orally treated with 25 or 50 mg/kg bw of AA for 3 weeks. Qualitative and quantitative immunohistochemical evaluation of glucagon and insulin expression and stereological analyses of pancreatic alpha and beta cells were performed. Serum insulin and glucose levels were measured. Analysis of glucagon-immunostained sections revealed a dose-dependent increase of intensity of glucagon immunopositive signal, alpha cell surface and numerical densities, volume density of alpha cell nuclei and nucleocytoplasmic ratio in AA-treated groups compared to the control. In insulin-immunolabeled pancreatic sections in AA-treated animals was observed decrease of intensity of insulin immunopositive signal, beta cell surface, numerical and volume densities and volume density of beta cell cytoplasm. Serum insulin and glucose concentrations remained unchanged after both AA treatments. The number of islets of Langerhans was not affected by AA treatment. Our results suggest that AA subchronic treatment of adult rats leads to remodeling of islet of Langerhans characterized by alpha cell expansion and beta cell mass reduction.

Abstract
The present study investigates the toxic effects of acrylamide (ACR) administered to rats at two doses on (i) oxidative stress and disruption of pro-oxidant/antioxidant balance in hepatic cells and (ii) its correlation with metallothioneins (MTs) genes expression, DNA damage and histomorphological changes. Treated rats with 20 and 40 mg/kg body weight of ACR led to an increase in malondialdehyde, hydrogen peroxide, advanced oxidation protein products, protein carbonyl levels as well as an alteration in the antioxidant status. Total MT content in the liver and MT I and MT II genes induction were increased. Plasma transaminases activities, albumin, total protein and glucose levels were also increased, while alkaline phosphatase activity was decreased. Moreover, total cholesterol (TC), triglyceride, low-density lipoprotein cholesterol (LDL-C) levels, TC/high-density lipoprotein cholesterol (HDL-C) and LDL-C/HDL-C ratios were increased, while HDL-C decreased in a dose-dependent manner. A random DNA degradation was observed only in the liver of ACR-treated rats with the highest dose. These changes were confirmed by histopathological observations.
