Abstract
Humans are exposed to various chemical elements that have been associated with the development and progression of diseases such as coronary artery disease (CAD). Unlike previous research, we employed a multi-element approach to investigate CAD patients and those with comorbid conditions such as diabetes (CAD-DM2), high blood pressure (CAD-HBP), or high blood lipids (CAD-HBL). Plasma concentrations of 21 elements, including lithium (Li), boron (B), aluminum (Al), calcium (Ca), titanium (Ti), vanadium (V), chromium (Cr), manganese (Mn), iron (Fe), cobalt (Co), nickel (Ni), copper (Cu), zinc (Zn), arsenic (As), selenium (Se), strontium (Sr), cadmium (Cd), tin (Sn), stibium (Sb), barium (Ba), and lead (Pb), were measured in CAD patients (n = 201) and healthy subjects (n = 110) using inductively coupled plasma-mass spectrometry (ICP-MS). Principal component analysis (PCA) and orthogonal partial least squares discriminant analysis (OPLS-DA) models were utilized to analyze the ionomic profiles. Spearman correlation analysis was employed to identify the interaction patterns among individual elements. We found that levels of Ba, Li, Ni, Zn and Pb were elevated in the CAD group compared to the healthy group, while Sb, Ca, Cu, Ti, Fe, and Se were lower. Furthermore, the CAD-DM2 group exhibited higher levels of Ni and Cd, while the CAD-HBP group showed lower levels of Co and Mn. In the CAD-HBL group, Ti was increased, whereas Ba, Cr, Cu, Co, Mn, and Ni were reduced. In conclusion, ionomic profiles can be utilized to differentiate CAD patients from healthy individuals, potentially providing insights for future treatment or dietary interventions.

Satarug S. Is Environmental Cadmium Exposure Causally Related to Diabetes and Obesity? Cells 2023; 13:83. [PMID: 38201287 PMCID: PMC10778334 DOI: 10.3390/cells13010083] [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: 11/28/2023] [Revised: 12/27/2023] [Accepted: 12/28/2023] [Indexed: 01/12/2024] Open
Abstract
Cadmium (Cd) is a pervasive toxic metal, present in most food types, cigarette smoke, and air. Most cells in the body will assimilate Cd, as its charge and ionic radius are similar to the essential metals, iron, zinc, and calcium (Fe, Zn, and Ca). Cd preferentially accumulates in the proximal tubular epithelium of the kidney, and is excreted in urine when these cells die. Thus, excretion of Cd reflects renal accumulation (body burden) and the current toxicity of Cd. The kidney is the only organ other than liver that produces and releases glucose into the circulation. Also, the kidney is responsible for filtration and the re-absorption of glucose. Cd is the least recognized diabetogenic substance although research performed in the 1980s demonstrated the diabetogenic effects of chronic oral Cd administration in neonatal rats. Approximately 10% of the global population are now living with diabetes and over 80% of these are overweight or obese. This association has fueled an intense search for any exogenous chemicals and lifestyle factors that could induce excessive weight gain. However, whilst epidemiological studies have clearly linked diabetes to Cd exposure, this appears to be independent of adiposity. This review highlights Cd exposure sources and levels associated with diabetes type 2 and the mechanisms by which Cd disrupts glucose metabolism. Special emphasis is on roles of the liver and kidney, and cellular stress responses and defenses, involving heme oxygenase-1 and -2 (HO-1 and HO-2). From heme degradation, both HO-1 and HO-2 release Fe, carbon monoxide, and a precursor substrate for producing a potent antioxidant, bilirubin. HO-2 appears to have also anti-diabetic and anti-obese actions. In old age, HO-2 deficient mice display a symptomatic spectrum of human diabetes, including hyperglycemia, insulin resistance, increased fat deposition, and hypertension.

Possible Combined Effects of Plasma Folate Levels, Global DNA Methylation, and Blood Cadmium Concentrations on Renal Cell Carcinoma. Nutrients 2023; 15:nu15040937. [PMID: 36839294 PMCID: PMC9959822 DOI: 10.3390/nu15040937] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/16/2023] [Revised: 02/02/2023] [Accepted: 02/10/2023] [Indexed: 02/15/2023] Open
Abstract
Epigenetic effects of environmental pollutants may be related to carcinogenesis. This study aimed to explore the association between the global DNA methylation marker: 5-methyl-2-deoxycytidine (5mdC) and renal cell carcinoma (RCC), and further investigated whether plasma folate and vitamin B12 levels and 5mdC modified the association between blood cadmium concentrations and RCC. We recruited 174 RCC patients and 673 non-RCC controls. Blood cadmium concentrations, plasma folate and vitamin B12 levels were measured. The amount of 5mdC in the DNA sample was expressed as percentages of the total cytosine content. An increase of 5mdC (%) and plasma folate and vitamin B12 levels were associated with decreasing odds ratio (OR) of RCC. Although plasma folate levels were not directly associated with 5mdC (%), a combined effect was observed with the odds of low plasma folate levels and low 5mdC (%) were greater among RCC patients compared to controls (OR (95% confidence interval, CI) = 11.86 (5.27-26.65)). Additionally, we observed that the odds of low plasma folate and high blood cadmium levels were greater among RCC patients than in controls (OR (95% CI): 8.15 (1.39-7.13)). This study provides suggestive evidence that plasma folate levels may modify the associations between 5mdC (%) or blood cadmium concentrations and RCC.

Effect of cadmium administration on the antioxidant system and neuronal death in the hippocampus of rats. Synapse 2022; 76:1-16.

Abstract
Cadmium (Cd) is a heavy metal classified as a carcinogen whose exposure could affect the function of the central nervous system. Studies suggest that Cd modifies neuronal morphology in the hippocampus and affects cognitive tasks. The oxidative stress pathway is proposed as a mechanism of toxicity. However, this mechanism is not precise yet. This study aimed to evaluate the effect of Cd administration on oxidative stress markers in the male rat's hippocampus. Male Wistar rats were divided into (1) control (drinking water) and (2) treatment with Cd (32.5 ppm of cadmium chloride (CdCl2 ) in water). The Cd was administered for 2, 3, and 4 months. The results show that the oral administration of CdCl2 increased the concentration of Cd in plasma and hippocampus, and this response is time-dependent on its administration. Likewise, it caused an increase in lipid peroxidation and nitrosative stress markers. Moreover, it increased reactive astrogliosis and antioxidant enzyme activity. Consequently, the progression of the oxidative response exacerbated neurodegeneration in hippocampal cells. Our results suggest that Cd exposure induces a severe oxidative response that contributes critically to hippocampal neurodegeneration. It is suggested that exposure to Cd increases the risk of developing neurological diseases, which contributes to a decrease in the quality of life of the human and the environment in which it lives.

OXIDATIVE MEDICINE AND CELLULAR LONGEVITY 2021; 2021:1427787.

Abstract
Maternal exposure to cadmium causes obesity and metabolic changes in the offspring, including nonalcoholic fatty liver disease-like pathology. However, whether maternal cadmium exposure accelerates liver cancer in the offspring is unknown. This study investigated the impact of early-life exposure to cadmium on the incidence and potential mechanisms of hepatocellular carcinoma (HCC) in offspring subjected to postweaning HCC induction. HCC in C57BL/6J mice was induced by diethylnitrosamine (DEN) injection at weaning, followed by a long-term high-fat choline-deficient (HFCD) diet. Before weaning, liver cadmium levels were significantly higher in mice with early-life cadmium exposure than in those without cadmium exposure. However, by 26 and 29 weeks of age, hepatic cadmium fell to control levels, while a significant decrease was observed in copper and iron in the liver. Both male and female cadmium-exposed mice showed increased body weight compared to non-cadmium-treated mice. For females, early-life cadmium exposure also worsened insulin intolerance but did not significantly promote DEN/HFCD diet-induced liver tumors. In contrast, in male mice, early-life cadmium exposure enhanced liver cancer induction by DEN/HFCD with high incidence and larger liver tumors. The liver peritumor tissue of early-life cadmium-exposed mice exhibited greater inflammation and disruption of fatty acid metabolism, accompanied by higher malondialdehyde and lower esterified triglyceride levels compared to mice without cadmium exposure. These findings suggest that early-life exposure to low-dose cadmium accelerates liver cancer development induced by a DEN/HFCD in male mice, probably due to chronic lipotoxicity and inflammation caused by increased uptake but decreased consumption of fatty acids.

Abstract
Background The present study was to investigate the potential mechanisms underlying the sub-chronic low-dose cadmium (Cd) exposure induced renal injury in rats. Methods Totally 40 male adult SD rats were randomly divided into four groups: control group, low-dose Cd group (1 mg/kg CdCl2), moderate-dose Cd group (2.5 mg/kg) and high-dose Cd group (5 mg/kg). Results From the 3rd week, the body weight of rats in moderate-dose and high-dose declined significantly as compared to the control group (P<0.05); the liver to body weight ratio increased, the volumes of 24-hour urine and drinking-water decreased markedly (P<0.05), the BUN, SCr and β2-MG increased significantly, but the Fe2+ concentration decreased markedly as compared to the control group (P<0.05); the serum MDA and SOD1 content contents increased, but the serum SOD2 and CAT contents decreased significantly in Cd-treated groups (P<0.05); Renal injury deteriorated with the increase in Cd dose; swelling glomeruli showed stenotic renal-tubules, and epithelial-cell-necrosis, shedding and accumulation in the lumen, massive infiltrated inflammatory cells and interstitial hyperaemia were observed; The mitochondria in renal-tubular-epithelial-cells displayed swelling, deformation and vacuolation; the renal ROS content increased in Cd-exposure-groups; the renal SOD1 expression increased but the expression of SOD2 and CAT decreased (P<0.05). The Bcl-2 expression decreased, but Bax expression and Bax/Bcl-2 ratio increased significantly in a Cd-dose dependent manner. Conclusions Cd may cause renal injury in a dose dependent manner, which may be ascribed to the disordered Fe2+ absorption, redox imbalance and apoptosis in the kidney.

Abstract
The harmful influences of dietary cadmium (Cd) on the chicken kidney and the protective role of selenium (Se) against Cd-induced nephrotoxicity in the chicken are relatively unexplored subjects. The aim of this study was to investigate the ameliorative role of Se on the effects of Cd-induced oxidative stress, endoplasmic reticulum stress, and apoptosis in chicken kidneys. For this study, 100-day-old chickens received Se (as 10 mg Na2SeO3/kg dry weight of diet), Cd (as 150 mg CdCl2/kg dry weight of diet), or Cd + Se in their diets for 60 days. Then, the histopathological changes, Cd and Se contents, levels of oxidative stress, inducible nitric oxide synthase-nitric oxide (iNOS-NO) system activity, levels of endoplasmic reticulum (ER) stress, results of the terminal deoxynucleotidyl transferase dUTP nick end labeling (TUNEL) assay of apoptosis, and expression levels of Bcl-2 and caspase 3 in the kidney were examined. The results showed that Cd exposure caused histopathological and ultrastructural damage and apoptosis of the kidneys. Cd administration significantly increased the accumulation of Cd, the malondialdehyde (MDA) content, NO production, iNOS activity, iNOS expression levels, expression levels of ER stress-related genes (GRP78, GRP94, ATF4, ATF6, and IRE) and the pro-apoptosis gene caspase 3, and the rate of apoptosis. Cd administration markedly decreased the Se content, superoxide dismutase (SOD) and glutathione peroxidase (GPx) activities, and anti-apoptosis gene Bcl-2 expression levels. Co-treatment with Se and Cd obviously reduced the accumulation of Cd, Cd-induced histopathological and ultrastructural changes, oxidative stress, iNOS-NO system activity, ER stress, caspase 3 expression levels, and the rate of apoptosis in the kidneys. These results suggested that Cd exposure caused renal injury and that Se ameliorated Cd-induced nephrotoxicity in chickens.

Abstract
Metals present in tobacco smoke have the ability to cause a pro-oxidant/antioxidant imbalance through the direct generation of free radicals in accordance with the Fenton or Haber-Weiss reaction and redox properties. Metals can also interact with antioxidant enzymes (superoxide dismutase, catalase, glutathione peroxidase) and small molecular antioxidants (glutathione) through binding to SH groups or by replacement of metals ions in the catalytic center of enzymes. Excessive free radicals production can induce an inflammatory response. The aim of this study was to review the information on the induction of inflammation by metals present in tobacco smoke such as lead (Pb), cadmium (Cd), arsenic (As), aluminum (Al), nickel (Ni) and mercury (Hg). In cellular immune response, it was demonstrated that radicals induced by metals can disrupt the transcription signaling pathway mediated by the mitogen-activated protein kinase (induced by Pb), NLRP3-ASC-caspase 1 (induced by Ni), tyrosine kinase Src (induced by As) and the nuclear factor κB (induced by Pb, Ni, Hg). The result of this is a gene transcription for early inflammatory cytokines, such as Interleukine 1β, Interleukine 6, and Tumor necrosis factor α). These cytokines can cause leukocytes recruitment and secretions of other pro-inflammatory cytokines and chemokines, which intensifies the inflammatory response. Some metals, such as cadmium (Cd), can activate an inflammatory response through tissue damage induction mediated by free radicals, which also results in leukocytes recruitment and cytokines secretions. Inflammation generated by metals can be reduced by metallothionein, which has the ability to scavenge free radicals and bind toxic metals through the release of Zn and oxidation of SH groups.

Abstract
Cadmium (Cd) is a widespread heavy metal used in numerous industrial processes. Cd exerts toxicological effects mostly in kidney and liver. Bone is also an important target of Cd, however, the cellular mechanisms of Cd toxicological effects in the bone cells are still poorly understood. Therefore, the present work aimed to investigate the putative cytotoxic and genotoxic effects of Cd to human bone cells. For that, the osteoblast-like MG-63 cells were exposed to 20 and 50μM Cd for 24 and 48h. Results showed a dose-dependent increase in Cd accumulation in cells and a decrease in cell viability, especially after 48h. Cell cycle analysis showed a delay at S phase concomitant with a decrease in cells at G0/G1 phase. After 24h, Cd treatment downregulated the expression of CHEK1, CHEK2 and CDK2 genes and upregulated the expression of CCNE1 gene. After 48h, the expression of ATM and CCNB1 genes were downregulated. Also, a 3.3 fold increase on the expression of gene CCNE1 was detected. Both Cd doses induced DNA fragmentation at 48h, while an increase in micronuclei (MN) and nucleoplasmic bridges (NPBs) together with an increase in the percentage of apoptotic/necrotic cells was detected for both time periods. Overall, our results demonstrate the cytotoxicity and genotoxicity of Cd in human bone cells. Also, the cytokinesis-block micronucleus (CBMN) assay parameters (MN, NPBs and the percentage of cells under apoptosis or necrosis) together with the cell cycle appear as the most sensitive to Cd cyto- and genotoxicity, being early affected even with the lowest Cd dose. Therefore, these cyto-/genotoxic techniques may be selected for early detection of Cd-induced toxicity.

Abstract
(1) Cadmium is a human carcinogen with unfavourable health impacts probably associated with its DNA methylation property. Recent data suggest that environmental cadmium exposure is associated with the incidence of myocardial infarction and peripheral arterial disease. Nonetheless, the effect of chronic cadmium exposure on cardiac contractile function remains unknown. (2) The present study was designed to examine the impact of low-dose cadmium exposure on cardiac contractile function and intracellular Ca2+ homeostasis. Adult male mice were exposed to cadmium for 4 weeks (20 nmol/kg, i.p. every other day for 4 weeks) with or without the DNA methylation inhibitor 5-aza-2'-deoxyctidene (5-AZA; 0.25 mg/kg, i.p., twice a week for 6 weeks, starting at the same time as cadmium administration). Cardiac contractile and intracellular Ca2+ properties were analysed, including echocardiographic left ventricular parameters, fractional shortening (FS), peak shortening (PS) amplitude, maximal velocity of shortening/relengthening (±dL/dt), time to PS (TPS), time to 90% relengthening (TR90 ), electrically stimulated increases in intracellular Ca2+ and intracellular Ca2+ decay. (3) Cadmium exposure depressed FS, PS, ±dL/dt and electrically stimulated increases in intracellular Ca2+ without affecting TPS, TR90 , intracellular Ca2+ levels or the decay rate. The effects of cadmium were significantly attenuated (PS) or blocked altogether (all other parameters) by 5-AZA. Cadmium exposure led to overt interstitial fibrosis (collagen deposition), which was mitigated by 5-AZA treatment. Western blot analysis revealed that cadmium exposure and/or 5-AZA treatment had no effect on the expression of intercellular adhesion molecule-1, tumour necrosis factor-α and cleaved caspase 3, suggesting a relatively minor role of proinflammatory cytokines and apoptosis in the cardiac responses to cadmium and 5-AZA. (4) Together, our data demonstrate, for the first time, direct cardiac depressant effects following cadmium exposure, which may be rescued by inhibition of DNA methylation.
