[PMID: 36565847 DOI: 10.1016/j.fct.2022.113576] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/08/2022] [Revised: 12/09/2022] [Accepted: 12/17/2022] [Indexed: 12/24/2022]
Abstract
Acrylamide (ACR) is formed during the cooking of starchy foods at high temperatures. Accumulating evidence has shown that ACR has toxic effects, but the mechanism of its potential reproductive toxicity remains unclear. In this study, we observed that ACR caused weight loss in mice. There was no significant difference in the weight of testis and epididymis between the low/medium-dose ACR group and the control group. And the number of epididymal sperms, testicular Leydig cells, serum testosterone level, testicular steroidogenic genes and enzymes, including cytochrome P450 family 11 subfamily A member 1 (CYP11A1) and cytochrome P450 family 17 subfamily A member 1 (CYP17A1), were decreased in the medium/high-dose ACR group. Additional cell experiments showed that the apoptosis rate and the level of reactive oxygen species (ROS) were increased, and testosterone levels and CYP17A1 protein expression were reduced in Leydig cells with treated ACR. Furthermore, the phosphorylation levels of extracellular signal-regulated kinases (ERK1/2) increased significantly; however, there was no significant difference in the levels of serine-threonine protein kinase (AKT) phosphorylation in the testis of mice and Leydig cells treated with ACR. These results suggest that ACR exposure leads to the damage of testicular structure and function and a decline in testosterone synthesis in Leydig cells and mouse testis, which may be related to the activated phosphorylation of ERK1/2.

Abstract
BACKGROUND Acrylamide, a component of fried foods, has been associated with several negative health outcomes. However, the relationship between dietary acrylamide and osteoporotic fractures has been explored by a few cross-sectional studies. AIMS To investigate if dietary acrylamide is associated with the onset of fractures in North American participants at high risk/having knee osteoarthritis (OA), over 8 years of follow-up. METHODS A Cox's regression analysis, adjusted for baseline confounders was run and the data were reported as hazard ratios (HRs) and 95% confidence intervals (CIs). Dietary acrylamide intake was assessed at the baseline using a food frequency questionnaire and categorized in tertiles (T), whilst fractures' history was recorded using self-reported information. RESULTS Altogether, 4,436 participants were included. Compared to participants with lower acrylamide intake (T1; < 3,313 μg), those with a higher acrylamide intake (T3; > 10,180 μg) reported a significantly higher risk of any fracture (HR = 1.37; 95% CI 1.12-1.68; p for trend = 0.009), forearm (HR = 1.73; 95% CI 1.09-2.77; p for trend = 0.04), spine (HR = 2.21; 95% CI 1.14-4.31; p for trend = 0.04), and hip fracture (HR = 4.09; 95% CI 1.29-12.96; p for trend = 0.046). CONCLUSIONS Our study is the first to report that high dietary acrylamide may be associated with an increased risk of osteoporotic fractures.

Abstract
BACKGROUND The aim of this study was to investigate the effects of acrylamide (AA) on fracture healing histologically, biochemically, and radiologically in a rat femur fracture model. METHODS Scanning electron microscopy (SEM) imaging and Fourier transform infrared spectroscopy (FTIR), and UV (ultraviolet)-Vis (visible) spectrophotometer examination were performed for acrylamide characterization. In this study, after the femur fracture model was created, the groups were formed to include eight rats in each group (G) as follows: G1: 15th-day control, G2: 15th-day AA, G3: 30th-day control, G4: 30th-day AA. In G2 and G4, 5mg/kg acrylamide was administered 3 times a week by gastric gavage. The fracture was evaluated radiologically according to Lane-Sandhu scoring and histologically according to Huo scoring. The weight changes of the rats were recorded. Albumin, total protein, cholesterol, HDL, LDL, triglyceride, ALP, LDH, vit. D, PTH, Ca, P, WBC, Hb, Plt values were examined in the blood samples. The data were analyzed using the SPSS program. RESULTS The characterization properties of acrylamide were confirmed. No significant weight change was observed in the rats during the study. When blood values were compared, a statistically significant difference was determined between albumin, total protein, phosphorus, white blood cell (WBC), and hemoglobin groups (p=0.41, p=0.00, p=0.003, p=0.019, and p=0,017, respectively). According to the histological score comparisons, G3 was significantly different from G1, G2, and G4 (p<0.05), and G4 was significantly different from G1 and G2 (p<0.05). According to Lane-Sandhu scoring, there was a significant difference between G2 and G3 and G4 (p: 0.0, p: 0.034), G1 and G3 (p: 0.001), respectively. CONCLUSION AA adversely affects fracture healing even at low doses, as in the present study. According to the results of this study, the authors recommend a diet poor in acrylamide during fracture treatment. Therefore, further human studies are required to find out the complex effect of AA on bone healing and the body.

Abstract
Mediation analysis aims to discover the role of intermediate variables from exposure to disease. The current study was performed to evaluate how vitamin D mediates the association between acrylamide hemoglobin biomarkers and obesity. Data were collected on 10,377 adults participating in the National Health and Nutrition Examination Survey (NHANES) 2003-2006 and 2013-2014 aged ≥ 18 years. Obesity was assessed through body mass index and abdominal circumference measurements. Generalized linear and restricted cubic spline (RCS) regression were used to estimate the association between vitamin D and acrylamide hemoglobin biomarkers, and the mediation effect of vitamin D was also discussed. After adjusting for potentially confounding factors, vitamin D had strong negative associations with serum concentrations of acrylamide hemoglobin adducts (HbAA, HbGA, and HbAA + HbGA). The RCS plots demonstrated that vitamin D was inversely and nonlinearly associated with HbAA and HbAA + HbGA while inversely and linearly associated with HbGA, and also a striking difference when vitamin D was lower than 60 nmol/L. Mediation analysis suggested that a negative correlation between acrylamide and obesity was mediated by vitamin D. The current study is expected to offer a fresh perspective on reducing the toxicity of acrylamide.

Clin Exp Pharmacol Physiol 2021; 48:1421-1429.

Abstract
The study investigated the effects of long-term glucocorticoid (GC) administration on bone remodelling, microstructure, and biomechanical strength in cortical and cancellous (trabecular) bones. Thirty-one female Sprague-Dawley rats were randomly divided into three dexamethasone (Dex) dosage groups, 1.0, 2.5, and 5.0 mg/kg twice a week for 8 weeks, and one control group treated with saline. At the end of the experiment, the tibia of one side and the fourth lumbar vertebrae were processed into sections for a histomorphometric analysis, while the femur of the same side and the fifth vertebrae were isolated for a biomechanical test. A dose-dependent decline in bone formation was observed in both trabecular and cortical (periosteal and endosteal) bones. In contrast, bone resorption was inhibited only in cancellous bone in the two higher dose groups and not dose-related. The ratio of Node/Termini increased, while marrow star volume (MSV) decreased in all Dex groups in metaphyseal trabecular bones, both of which were dose-dependent. Subendosteal cortex porosity increased in parallel with non-uniform trabecular distribution, but cortical thickness remained unchanged. Interestingly, there were no significant changes in microstructure or mechanical strength in lumbar trabecular bone. The cortical elastic load was dose-independently reduced in all three Dex groups when compared with the control group. In summary, bone remodelling was dose-dependently inhibited in cancellous bones but enhanced in intracortical bones. The non-uniform distribution of trabecular bone and increased porosity in the inner edge of cortical bone were both in parallel with GC dosage, and the porosity increase was more likely to occur, leading to reduced cortical mechanical strength.

Abstract
Abstract
Acrylamide (AA) is a chemical substance with a potentially carcinogenic effect. Its presence in food or animal food arises from its thermal processing. The experiment was conducted to evaluate the effect of AA exposure (3.0 mg/kg. b.w./day) of pregnant dams during the second half of the pregnancy on bone development in offspring. As an model animal, guinea pig was used. While term body weight of newborns was not influenced by maternal AA treatment, shorter bones with reduced bone diaphysis cross-sectional area were observed in experimental group. Numerous negative, offspring sex-dependent effects of maternal AA exposure were observed in femoral epiphysis and metaphysis as well as the articular and growth plate cartilages. These effects resulted from the AA-induced alterations in bone metabolism, as indicated by the changes in the expression of numerous proteins involved in bone development: receptor activator of nuclear factor kappa-Β ligand (RANKL), tissue inhibitor of metalloproteinases 2 (TIMP-2), bone morphogenetic protein 2 (BMP-2), vascular endothelial growth factor (VEGF), and cartilage oligomeric matrix protein (COMP), all of whose expression was measured as well as distribution of immature collagen fibres was determined. Based on the results, it can be concluded that the exposure of pregnant dams to AA negatively affected the structure of compact bone in bone diaphysis, microarchitecture of trabecular bone in metaphysis and epiphysis as well as the structure of the articular and growth plate cartilages in their offspring. The AA-induced bone impairment increased osteoclast differentiation, as observed through the change in the RANKL/OPG ratio, which in turn inhibited osteoblast function by decreasing the expression of other proteins. The data of the present study suggests that maternal AA exposure can result in insufficient bone gain and even bone loss after the birth.

Abstract
Acrylamide is a toxic chemical substance produced when starch-rich foods are fried at high temperatures. Asthma is a chronic and complicated respiratory disease, of which genetic and environmental factors are the main triggers. Orally-received components may have an effect on asthma pathophysiology. The aim of this study was to investigate the role of AA as a stimulus in asthma. BALB/c mice were allocated into four groups as follows: two OVA-sensitized asthmatic groups, including one treated with AA by gavage feeding and one non-treated (asthma group), and two healthy (non-asthmatic) groups, one treated with AA by gavage feeding and one non-treated (negative control group). Airway hyperresponsiveness, cell count, cytokine levels in BAL fluid, lung histopathology, IgE levels, and oxidative stress indices including plasma level of MDA, pulmonary antioxidant enzymes (SOD and CAT) levels, HP content, and collagen fiber accumulation in lung tissue were measured. We found that the group of mice treated with both OVA and AA (asthmatic and AA-treated mice) experienced higher levels of asthma-associated biomarkers, including higher enhanced pause (Penh value), eosinophilic inflammation, mucus hyper secretion, goblet cell hyperplasia, total and OVA-specific IgE levels, IL-4, IL-5, and IL-13 levels than the group sensitized only with OVA (asthmatic mice). The OVA-AA-treated mice also experienced worsened levels of oxidative stress indicators. Healthy (non-asthmatic) mice that only received AA were in similar conditions to healthy untreated mice (negative control group). The OVA-AA-treated group showed more severe allergic asthma symptoms in comparison to the group only sensitized with OVA. Therefore, food/water contaminated with AA can act as a stimulant of allergic asthma and exacerbate the bronchial inflammatory responses.

Abstract
Simple Summary Alcohol consumption, the drinking of beverages containing ethanol, represents a growing problem worldwide. Alcohol intake is often combined with an improper diet based on highly processed starch products that are rich in acrylamide. Both acrylamide and alcohol have a harmful impact on bone health. We previously demonstrated that adverse effects of ethanol on cortical bone structure were partly reduced by a relatively high dose of acrylamide in mice after one remodelling cycle. The present research was designated to reveal whether the antagonistic impact of both aforementioned toxins can also be achieved using a lower dose of acrylamide. According to our results, individual administrations of acrylamide and ethanol had adverse impacts on biochemical and morphological parameters consistent with bone health in mice. However, the most detrimental effects of ethanol were again alleviated by acrylamide at the dose used in this study. Abstract The aim of present study was to verify antagonistic effect of acrylamide (AA) and ethanol (Et) on bone quality parameters. Adult mice (n = 20) were segregated into four groups following 2 weeks administration of toxins: group E1, which received AA (20 mg/kg body weight daily); group E2, which received 15% Et (1.7 g 100% Et/kg body weight daily); group E12, which received simultaneously both toxins; and a control group. An insignificant impact of individual applications of AA, Et or their simultaneous supplementation on the total body weight of mice and the length and weight of their femoral bones was identified. In group E1, higher levels of alanine aminotransferase (ALT), aspartate aminotransferase (AST), triglyceride (TG), a decreased level of glutathione (GSH) and elevated endocortical bone remodelling were determined. A significantly lower relative volume of cortical bone, bone mineral density (BMD), elevated endocortical bone remodelling and cortical porosity, higher levels of ALT, AST, lower values for total proteins (TP), GSH, alkaline phosphatase (ALP), calcium, and phosphorus were recorded in group E2. In the mice from group E12, the highest endocortical bone remodelling, decreased values for BMD, TP, GSH and ALP and increased levels of ALT and AST were found. Our findings confirmed the antagonistic impact of AA and Et at doses used in this study on biochemical and morphological parameters consistent with bone health in an animal model.
