Effects of Periconception Cadmium and Mercury Co-Administration to Mice on Indices of Chronic Diseases in Male Offspring at Maturity. ENVIRONMENTAL HEALTH PERSPECTIVES 2017; 125:643-650. [PMID: 27814245 PMCID: PMC5381999 DOI: 10.1289/ehp481] [Citation(s) in RCA: 5] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Figures] [Subscribe] [Scholar Register] [Received: 05/09/2016] [Revised: 10/17/2016] [Accepted: 10/18/2016] [Indexed: 06/06/2023]
Abstract
BACKGROUND Long-term exposure to the heavy metals cadmium (Cd) and mercury (Hg) is known to increase the risk of chronic diseases. However, to our knowledge, exposure to Cd and Hg beginning at the periconception period has not been studied to date. OBJECTIVE We examined the effect of Cd and Hg that were co-administered during early development on indices of chronic diseases in adult male mice. METHODS Adult female CD1 mice were subcutaneously administered a combination of cadmium chloride (CdCl2) and methylmercury (II) chloride (CH3HgCl) (0, 0.125, 0.5, or 2.0 mg/kg body weight each) 4 days before and 4 days after conception (8 days total). Indices of anxiety-like behavior, glucose homeostasis, endocrine and molecular markers of insulin resistance, and organ weights were examined in adult male offspring. RESULTS Increased anxiety-like behavior, impaired glucose homeostasis, and higher body weight and abdominal adipose tissue weight were observed in male offspring of treated females compared with controls. Significantly increased serum leptin and insulin concentrations and impaired insulin tolerance in the male offspring of dams treated with 2.0 mg/kg body weight of Cd and Hg suggested insulin resistance. Altered mRNA abundance for genes associated with glucose and lipid homeostasis (GLUT4, IRS1, FASN, ACACA, FATP2, CD36, and G6PC) in liver and abdominal adipose tissues as well as increased IRS1 phosphorylation in liver (Ser 307) provided further evidence of insulin resistance. CONCLUSIONS Results suggest that the co-administration of Cd and Hg to female mice during the early development of their offspring (the periconception period) was associated with anxiety-like behavior, altered glucose metabolism, and insulin resistance in male offspring at adulthood.

Abstract
In this work we compared the cadmium (Cd), copper (Cu), lead (Pb), and zinc (Zn) contents of muscle, liver and placenta of gestating females of the viviparous shark Rhizoprionodon longurio and of muscle, liver and umbilical cord of their respective embryos. The higher values of the essential Cu and Zn were in embryonic or embryo-related tissues (placenta and umbilical cord). Maternal muscle and liver had the highest values of Pb and Cd, respectively. There were significant direct correlations between the Zn and Cd concentrations of placenta and umbilical cord, as well as between maternal muscle and embryonic livers for Pb and Cd, but the relation between these tissues was inverse in the case of Zn. All correlations between the metal content of embryonic tissues and size of the embryos were negative, suggesting an inverse relation between the rate of mother-to-embryo metal transfer and embryonic growth.

Abstract
Cadmium (Cd) is a common environmental contaminant. Adult exposure to Cd alters the immune system, however, there are limited studies on the effects of prenatal exposure to Cd. Pregnant C57Bl/6 mice were exposed to an environmentally relevant dose of CdCl(2) (10 ppm) and the effects on the immune system of the offspring were assessed at 20 weeks of age. Prenatal Cd exposure caused an increase in the percent of CD4(-)CD8(-)CD44(+)CD25(-) (DN1) thymocytes in both sexes and a decrease in the percent of CD4(-)CD8(-)CD44(-)CD25(+) (DN3) thymocytes in females. Females had an increase in the percent of splenic CD4(+) T cells, CD8(+) T cells, and CD45R/B220(+) B cells and a decrease in the percent of NK cells and granulocytes (Gr-1(+)). Males had an increase in the percent of splenic CD4(+) T cells and CD45R/B220(+) B cells and a decrease in the percent of CD8(+) T cells, NK cells, and granulocytes. The percentage of neutrophils and myeloid-derived suppressor cells were reduced in both sexes. The percent of splenic nTreg cells was decreased in all Cd-exposed offspring. Cd-exposed offspring were immunized with a streptococcal vaccine and the antibody response was determined. PC-specific serum antibody titers were decreased in Cd exposed female offspring but increased in the males. PspA-specific serum IgG titers were increased in both females and males compared to control animals. Females had a decrease in PspA-specific serum IgM antibody titers. Females and males had a decrease in the number of splenic anti-PspA antibody-secreting cells when standardized to the number of B cells. These findings demonstrate that very low levels of Cd exposure during gestation can result in long term sex-specific alterations on the immune system of the offspring.

Abstract
It has been suggested that the toxic effects of cadmium (Cd) are the result of interactions with essential metals, such as zinc (Zn) and copper (Cu). Previous studies have shown altered Zn and/or Cu levels in the tissues of rodents that drank water supplemented with >50 ppm Cd. To evaluate the effects of lower level Cd exposure on maternal and neonatal Zn and Cu levels and on the reproductive organs of female offspring, mice were exposed to 0, 1 and 10 ppm Cd in the drinking water from conception to 10 days after birth. The Cd concentrations in the brains of the offspring were higher in the exposed group than in the control group at birth. In the kidneys and livers, the Cd concentrations were higher in the Cd-exposed group 10 days after birth. At birth, increased Zn concentrations were observed in the kidneys and livers of the Cd-exposed offspring, although the Cd concentrations in these tissues did not differ between the exposed and non-exposed groups. The hepatic Cu concentrations of the exposed mice tended to be lower than those of the control mice at birth and were significantly lower 10 days after birth. In addition, Cd exposure tended to delay the timing of vaginal opening and perturbed the estrous cycles of the female offspring. These findings suggest that perinatal Cd exposure, even at low levels, affects the Zn and Cu concentrations of neonates and the reproductive functions of female offspring.

Abstract
Lactating rats were exposed to 0, 5 or 25ppm cadmium as cadmium chloride in the drinking water. A battery of neurobehavioural tests was applied to the male offspring after weaning at 5 weeks until 4 months of age. The mean cadmium levels in exposed pup kidneys ranged from 0.006 to 0.030mg/kg wet weight at weaning, with the corresponding maternal kidney cadmium levels ranging from 4 to 13mg/kg wet weight. Significantly increased activity during the initial 20min of the spontaneous motor activity test was observed in the highest-dose group compared to the control group. The activity outcome was significantly positively correlated with cadmium levels in the pup kidneys. No cadmium-related changes in performance were observed in the Morris water maze, the E-shaped maze or the elevated plus-maze. The results indicate that neurobehavioural effects during development may be a more sensitive parameter for Cd toxicity than renal dysfunction.

Abstract
The objective of this study was to evaluate the presence of heavy metals in the hepatocytes of the animals fed a cadmium-supplemented diet and also receiving zinc and/or selenium in the injection form. The experiment involved four groups of calves (6-8, both sexes) receiving the heavy metals in various combinations for 95 days. Electron micrographs of liver cells were prepared and statistically evaluated using Student's t-test. A modified morphometric apparatus was used for morphometric examination. Exogenous cadmium showed marked accumulation in the hepatocytes. If, however, the cadmium diet was combined with zinc or selenium administration the amount of the reduction product was much lower.

Abstract
Studies to identify the mechanisms underlying the teratogenic effects of cadmium (Cd2+) have been complicated by the inherent difficulties of chronically and subchronically administering specific doses of Cd2+ to gravid animals under strictly controlled conditions. The objective of the present study was to develop a relatively simple animal model for examining the teratogenic effects of subchronic Cd2+ exposure. Cd2+ was administered to gravid CF-1 mice by subcutaneously implanted Alzet osmotic minipumps, which released fixed amounts of Cd2+ over a 14-day period between days 5 and 18 of gestation. The results showed that Cd2+ administered in this manner produced fetal anomalies and that the patterns of Cd2+ distribution and the specific developmental defects were similar to those that have been reported for other routes of Cd2+ administration. These findings indicate that osmotic minipumps may serve as useful tools in long-term studies of Cd2+ teratogenicity. They would appear to be especially useful in teratogenic evaluations where minimizing maternal stress and administering precise doses of Cd2+ are important.

Abstract
In human chorionic villus tissue at the 10-17th week of a normal pregnancy, heat shock proteins (hsp70, hsp73, hsp85, and hsp105) were induced in vitro by a heat shock or by exposure to sodium arsenite or cadmium chloride. In dispersed cells of the whole mouse embryo on the 11th day of development, heat shock proteins (hsp73 and hsp105) were induced by a heat shock or by exposure to sodium arsenite, but not by exposure to cadmium chloride. After a maternal hyperthermia or an intraperitoneal injection of sodium arsenite or cadmium chloride into a pregnant mouse, heat shock proteins accumulated in the embryo on the 9th day of development, especially in the neuroepithelial tissue. The significance of heat shock proteins in the embryo is discussed.

Abstract
The effects of cadmium exposure during pregnancy (by means of daily subcutaneous injections of 4.4 mumol/kg to the mother) on the neonates were investigated. No effect was observed on fetal or neonatal body weights, nor on neonatal liver weights. These parameters were examined up to 5 weeks after birth. The weight of neonatal thymuses was decreased 7 and 14 days after birth due to cadmium exposure of the mothers as compared with controls. This may be caused by zinc deficiency, because zinc concentrations in fetal and neonatal livers after cadmium exposure were found to be very low 20 days after conception and 5 h after birth. Cadmium concentration in neonatal liver decreased; however, cadmium in malignant liver increased as age increased. In the mother, cadmium was transferred to the milk, as it was demonstrated in the stomach contents of the pups. Simultaneous administration of zinc in amounts equimolar to cadmium did not have any noticeable effect on the amount of cadmium transferred to the fetus or on cadmium concentrations in any of the organs investigated. It could not prevent zinc deficiency in fetal and neonatal liver. In addition, growth retardation of the thymus from exposed pups could not be prevented by zinc administration.

Abstract
The presence of metallothionein (MT) was demonstrated in placentae from cadmium-exposed and control rats by an immunohistochemical technique, using peroxidase as label and the diaminobenzidine procedure for the staining reaction. The protein was found in different regions of the placenta, i.e. in trophoblastic labyrinth, in spongiotrophoblast and in visceral yolk sac. Cytophotometric analysis of the final reaction product revealed that the amount of MT was increased in the placental labyrinth of cadmium-exposed rats. Increases were found in both nuclei and cytoplasm of trophoblast cells in the labyrinth region. Possible roles of MT in the transport of zinc and in the carbohydrate metabolism are discussed.
