Abstract
Regulated cell death (RCD), also known as programmed cell death (PCD), plays a critical role in various biological processes, such as tissue injury/repair, development, and homeostasis. Dysregulation of RCD pathways can lead to the development of many human diseases, such as cancer, neurodegenerative disorders, and cardiovascular diseases. Maintaining proper metal ion homeostasis is critical for human health. However, imbalances in metal levels within cells can result in cytotoxicity and cell death, leading to a variety of diseases and health problems. In recent years, new types of metal overload-induced cell death have been identified, including ferroptosis, cuproptosis, and calcicoptosis. This has prompted us to examine the three defined metal-dependent cell death types, and discuss other metals-induced ferroptosis, cuproptosis, and disrupted Ca2+ homeostasis, as well as the roles of Zn2+ in metals' homeostasis and related RCD. We have reviewed the connection between metals-induced RCD and various diseases, as well as the underlying mechanisms. We believe that further research in this area will lead to the discovery of novel types of metal-dependent RCD, a better understanding of the underlying mechanisms, and the development of new therapeutic strategies for human diseases.

Potential effect of luteolin, epiafzelechin, and albigenin on rats under cadmium-induced inflammatory insult: In silico and in vivo approach. Front Chem 2023; 11:1036478. [PMID: 36936530 PMCID: PMC10016615 DOI: 10.3389/fchem.2023.1036478] [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: 09/04/2022] [Accepted: 01/19/2023] [Indexed: 03/06/2023] Open
Abstract
Introduction: Cadmium(Cd) an industrial poison present abundantly in the environment, causes human toxicity by an inflammatory process. Chronic exposure of cadmium can cause a number of molecular lesions that could be relevant to oncogenesis, through indirect or epigenetic mechanisms, potentially including abnormal activation of oncogenes and suppression of apoptosis by depletion of antioxidants. As induction of cyclooxygenase (COX)-2 is linked to inflammatory processes, use of luteolin, epiafzelechin, and albigenin alone or in different combinations may be used as anti-inflammatory therapeutic agents. Methods: We, herein, performed in silico experiments to check the binding affinity of phytochemicals and their therapeutic effect against COX-2 in cadmium administered rats. Wistar albino rats were given phytochemicals in different combinations to check their anti-inflammatory activities against cadmium intoxication. The level of alanine aminotransferases (ALT), 4-hydroxynonenal (4HNE), 8-hydroxy-2-deoxyguanosine (8-OHdG), tumor necrosis factor-alpha (TNF-α), isoprostanes (IsoP-2α), COX-2, and malondialdehyde (MDA) were estimated with their respective ELISA and spectrophotometric methods. Results: The generated results show that phytocompounds possessed good binding energy potential against COX-2, and common interactive behavior was observed in all docking studies. Moreover, the level of ALT, 4HNE, 8-OHdG, TNF-α, IsoP-2α, malondialdehyde, and COX-2 were significantly increased in rats with induced toxicity compared to the control group, whereas in combinational therapy of phytocompounds, the levels were significantly decreased in the group. Discussion: Taken together, luteolin, epiafzelechin, and albigenin can be used as anti-inflammatory therapeutic agents for future novel drug design, and thus it may have therapeutic importance against cadmium toxicity.

Abstract
Lead (Pb), is an environmental toxicant, causes multi-organ dysfunction including reproductive impairments. This study designed to investigate the prospective antioxidative, anti-inflammatory and anti-apoptotic effects of ellagic acid (EA) on Pb-mediated testicular and hepato-renal toxicity. Four experimental groups of five male Long-Evans rats each were used: control, Pb (60 mg/kg), EA (30 mg/kg), and Pb + EA groups. All groups were given their respective treatment orally for 30 days. Pb exposure altered body and organs weight, food and water consumption, rectal temperature, Pb residue levels in tissues, liver and kidney function, sperm quality parameters, serum metabolic and hematology profiles, and impaired the oxidative/antioxidative balance in the testicular and hepato-renal tissue, as shown by the decreased antioxidant proteins (superoxide dismutase, catalase, glutathione peroxidase, and reduced glutathione) and increased the oxidative (MDA, lipid hydroperoxides, conjugated dienes, protein carbonyl, fragmented DNA and GSH:GSSG ratio) stress and inflammatory (IL-1, IL-6, TNF-α, prostaglandin, LTB4, NO, myeloperoxidase, LDH) markers. Moreover, a dysregulation in the stress response (HSP-70) and apoptotic-regulating proteins (BAX, BCL-2, and active Caspase-3) were recorded upon Pb exposure. Remarkably, EA oral administration reduced the Pb residue levels in tissues, improved the liver and kidney function, revived the spermatogenesis and sperm quality, restored redox homeostasis, suppressed the oxidative stress, inflammatory and apoptotic responses in the liver, kidney and testis tissue. Our findings point out that EA can be used as a phyto-chelator to overcome the adverse effects of Pb exposure due to its potent antioxidant, anti-inflammatory, and anti-apoptotic effects.

Abstract
Increasing evidence has demonstrated that cadmium (Cd), a common environmental toxicant, has been associated with testicular toxicity. Quercetin, an efficient flavonoid, has been shown to exert cytoprotective effect in numerous pathological processes. The current study has employed ultrastructural analysis to examine the Cd-induced toxicity in goat testicular tissue along with the ameliorative action of quercetin in a dose- and time-dependent manner in-vitro. Results of transmission electron microscopy (TEM) revealed that at lower selected concentrations (10 and 50 µM), Cd induced apoptosis-mediated cytotoxicity in testicular tissue as supported by presence of various morphological attributes of apoptosis in testicular germ cells such as condensed and marginated chromatin followed by breakdown of chromatin material, swollen mitochondria, and vacuolization. At 100 µM concentration, along with apoptosis, Cd-induced cytotoxicity in testicular tissue was associated with induction of necrosis also. However, the simultaneous supplementation of antioxidant quercetin has markedly abrogated the testicular cytotoxicity as shown by restoration of Cd-evoked aberrant ultrastructure of testicular germ cells in a dose- and time-dependent manner, providing a basis for future studies to involve quercetin in management of Cd-induced reproductive toxicity in males.

[PMID: 32569717 DOI: 10.1016/j.jep.2020.113060] [Citation(s) in RCA: 33] [Impact Index Per Article: 8.3] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 02/10/2020] [Revised: 03/19/2020] [Accepted: 05/31/2020] [Indexed: 06/11/2023]
Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Polygonatum sibiricum (PS), the dried rhizome of the liliaceous plant including P. sibiricum Red., P. cyrtonema Hua. and P. kingianum Coll. et Hemsl., is a widely used Chinese herbal medicines. It was first published in "Special Records of Famous Doctors", in which is described to replenished Qi and nourish Yin, strengthening the spleen and nourishing the lungs and kidney. Based on the principle of kidney controlling the reproduction, kidney-tonifying therapy has traditionally been seen as most applicable to the treatment of infertility. The current investigation has focused on the protective effect of PS against cadmium-induced testicular injury in mice. AIM OF THE STUDY To investigate the protective effect of PS against cadmium-induced testicular injury in mice via the TXNIP-NLRP3-Caspase-1 and CytC-Caspase-9-Caspase-3 pathways. MATERIALS AND METHODS PS was processed into Polygonatum sibiricum aqueous extract (PSAE). A mouse testicular injury model was established by a single intraperitoneal (i.p.) injection of cadmium chloride (CdCl2) (2.5 mg/kg b.w.), and the mice were treated intragastrically with PSAE (10 g/kg b.w.) once daily for 35 consecutive days. At the end of the experiment blood and testicular tissue samples were collected to analyze sperm survival rate and sperm deformity rate, serum testosterone T content, testicular oxidation related indicators levels (SOD, MDA, GSH, CAT) in testicular tissue, and histopathological changes of testicular tissues. The testicular cell cycle and reactive oxygen species (ROS) levels were measured by flow cytometry, the expression levels of thioredoxin-interacting protein (TXNIP), nucleotide-binding oligomerization domain-like receptor protein 3 (NLRP3), Caspase-1, interleukin (IL)-1β, Cyctochrome C (CytC), Caspase-3, and Caspase-9 mRNA in testicular tissue were detected by qRT-PCR and the protein expression levels of TXNIP, NLRP3, Caspase-1, CytC, Caspase-3, and Caspase-9 were detected by Western blot and immunohistochemical method. RESULTS The results indicated that compared with the model group, PSAE brought testicular weight to a near-normal range, improved sperm survival rate and reduced sperm abnormality rate, elevated the level of testosterone, made the damaged testis tissue recover to near normal, reduced the level of ROS, and inhibited testicular cell apoptosis. Further study showed that PSAE significantly decreased the levels of relative genes and proteins in testicular cells, such as TXNIP, NLRP3, Caspase-1, IL-1β, CytC, Caspase-3, and Caspase-9, which suggested that PSAE could regulate oxidative stress through the TXNIP-NLRP3-Caspase-1 signaling pathway, and inhibit apoptosis in the mitochondrial pathway via CytC-Caspase-9-Caspase-3 pathway. In summary, we have confirmed that PSAE exerted a powerful protective effect on CdCl2-induced testicular injury in mice through inhibiting oxidative stress and mitochondria-mediated apoptosis.

Abstract
The study evaluated the protective effect of Costus afer on low-dose heavy metal mixture (LDHMM)-mediated effects in the testis of albino rats. The weight-matched animals were divided into six groups: normal control, metal mixture of (PbCl2 + CdCl2 + HgCl2 ), combination of metal mixture + Costus afer at 750 mg/kg, combination of metal mixture + Costus afer at 1,500 mg/kg, combination of metal mixture + Costus afer at 2,250 mg/kg and combination of metal mixture + (ZnCl2 ). LDHMM reduced (p < .05) the antioxidant biomarkers (superoxide dismutase, SOD; catalase, CAT; and glutathione, GSH) and increased (p < .05) the lipid peroxidation marker (malondialdehyde, MDA) and lead, cadmium and mercury concentrations in the testis. Treatment with LDHMM increased (p < .05) abnormal sperm morphology and plasma prolactin (PRL) level and decreased epididymal sperm count, viability, follicle-stimulating hormone (FSH), luteinising hormone (LH) and testosterone. LDHMM exposure caused deleterious changes in the testis. Treatment of rats with Costus afer (750, 1,500 and 2,250 mg/kg) dose-dependently reduced (p < .05) the LDHMM-mediated toxicity. Treatment with Costus afer also reversed the testicular weight and LDHMM decrease in antioxidant biomarkers. Costus afer may be a defensive modulator of LDHMM-mediated testicular lesions.

Abstract
Cadmium (Cd) exposure can cause reproductive toxicity through oxidative stress and inflammatory response. A polysaccharide extract of the edible mushroom Agaricus blazei Murill has been isolated and exhibits antioxidant activity and immunoregulatory effect. The aim of this study was to investigate the protective role of Agaricus blazei polysaccharide (ABP) against Cd-induced damage in chicken testis through enhancing antioxidant activity and alleviating inflammatory response. One hundred twenty healthy 7-day-old Hy-Line male chickens (Harbin, China) were randomly divided into four groups, and each group consisted of 30 chickens: Normal control was fed daily with full feed and 0.2 mL distilled water per day via oral gavage; Cd-treated group was fed daily with full feed that contained 140 mg/kg CdCl2 and 0.2 mL distilled water per day by gavage; Polysaccharide-treated group was fed daily with full feed with 0.2 mL ABP(30 mg/ml) solution per day via oral gavage; Cd/polysaccharide-treated group was fed daily with full feed containing 140 mg/kg CdCl2 and 0.2 mL ABP(30 mg/ml) solution per day by gavage. On the 20, 40, and 60 days, the testis was immediately removed. The contents of Cd in the testis, activities of superoxide dismutase (SOD) and glutathione peroxidase (GSH-Px), malondialdehyde (MDA) production, messenger RNA (m RNA) levels of tumor necrosis factor-alpha (TNF-α), interleukin-1 beta (IL-1β), and interleukin-6 (IL-6), protein expressions of heat shock proteins (HSPs) (HSP60, HSP70, and HSP90), and the histopathological changes of the testis were determined. The results indicated that ABP improved Cd-caused testicular tissue damage by increasing the SOD and GSH-Px activities: decreasing the Cd accumulation and MDA content, mRNA levels of TNF-α, IL-1β, and IL-6, and protein expressions of HSP60, HSP70, and HSP90. Results suggest that ABP for the mitigation of damage induced by cadmium in chicken testis through enhancing antioxidant activity and alleviating Inflammatory response.

Abstract
Over the past decades, an increase has been described in exposure to environmental toxins; consequently, a series of studies has been carried out with the aim of identifying problems associated with health. One of the main risk factors is exposure to heavy metals. The adverse effects that these compounds exert on health are quite complex and difficult to elucidate, in that they act at different levels and there are various signaling pathways that are implicated in the mechanisms of damage. The Sertoli cells plays a role of vital importance during the process of spermatogenesis, and it has been identified as one of the principal targets of heavy metals. In the present review, cadmium, lead, and arsenic are broached as altering the physiology of the Sertoli cells, citing mechanisms that have been cited in the literature.

Abstract
Cadmium chloride (Cd) is a potent endocrine disruptor and may cause the malformation in the male reproductive tract. However, the effects of a single in utero exposure to low doses of Cd on fetal Leydig cell development are still unknown. The objective of this study is to investigate the effects of a single in utero exposure to low doses of Cd on rat fetal Leydig cell development. Adult 64-day-old Sprague-Dawley dams received a single intraperitoneal injection of 0, 0.25, 0.5, and 1.0 mg/kg Cd on gestational day 12. Cd dose-dependently reduced testosterone production of fetal testis, lowered fetal Leydig cell numbers, downregulated protein expression levels of Leydig (LHCGR, SCARB1, STAR, CYP11A1, HSD3B1, and CYP17A1), and Sertoli cells (HSD17B3, DHH, and FSHR). In conclusion, our results demonstrated that a single in utero exposure to low doses of Cd blocked fetal Leydig cell development.

Abstract
The Sertoli cell plays a vital role during the spermatogenesis process and has been identified as one of the main targets of the toxic action of heavy metals on the seminiferous epithelium. In the present work, the effect of lead (Pb), Arsenic (As), and Cadmium (Cd) in primary cultures of Sertoli cells was analyzed by measuring the expression of the genes Cldn11, Ocln, and Gja1 that participate in the tight and gap junctions, which are responsible for maintaining the blood-testis barrier. Sertoli cells were isolated from the testes of Wistar rats. Sertoli cell cultures were exposed separately and at the same concentrations of three heavy metals for 48 h. Subsequently, gene expression was measured by real-time polymerase chain reaction. In the morphological analysis of the cultures, after 24 h, the cultures exposed to Cd showed greatest detachment of the monolayer, followed by those exposed to As and Pb. As for gene expression patterns, As induced a decrease in the expression of the Cldn11 gene at 24 and 48 h (p < 0.01) and in that of Ocln at 24 (p < 0.001) and 48 h (p < 0.01), whereas Cd induced overexpression of the Gja1 gene from day 1 of exposure (p < 0.001) and subexpression of the Ocln gene (p < 0.05) at 24 h. Because each of these three metals generated different expression patterns in the three genes, we can postulate that the mechanisms of damage that they induce are different; therefore, the effect that they exert on the Sertoli cell occurs through different pathways, generating changes in structural proteins, altering Sertoli cell morphology, and compromising its function in the regulation of the spermatogenesis process.

Abstract
Metallothionein (MT) has a characteristic molecular structure with a cysteine-rich content. This unique structure provides metal-binding and redox capabilities and promoting metal homeostasis and detoxification in living animals. In order to evaluate the effects of cadmium (Cd) on hepatic MT expression in the liver of Acrossocheilus fasciatus, we obtained the complete cDNA of the A. fasciatus liver MT for the first time. The MT cDNA contains a 605-bp sequence, which codes for 60 amino acids. Protein alignment showed that the similarity between MT protein sequences of A. fasciatus and those of other vertebrates (especially teleosts) was very high and a cysteine residue structure was also conserved. MT was detected in the liver, kidney, gill, testis, muscle, spleen, heart and brain tissues of A. fasciatus by tissue-specific expression analysis. After Cd exposure, Cd/hemoglobin saturation assay, immunohistochemistry and reverse-transcription quantitative PCR (RT-qPCR) were used to describe MT expression in liver tissue. These techniques indicate a sensitive response by liver MT to Cd exposure. The results suggest that A. fasciatus MT may play an important role in the detoxification processes in the liver, and also would be a useful biomarker for monitoring metal pollution in aquatic environments. In addition, A. fasciatus could be regarded as one candidate for a model species for bony fishes in ecotoxicology.

Abstract
Trace metal ions and trace organic compounds are common co-contaminants in the environment that pose risks to human health. We evaluated the effects of four metal ions (As(3+), Cu(2+), Hg(2+), and Zn(2+)) on 2,3,7,8-tetrachlorodibenzo-p-dioxin (TCDD) induced cytotoxicity and the expression of the cytochrome P4501A1 gene (cyp1a1) in the zebrafish liver (ZFL) cell line. A metal accumulation study showed that Cu and Zn did not accumulate in ZFL cells. However, As and Hg did accumulate, which resulted in the inhibition of TCDD-mediated induction of cyp1a1 mRNA and protein expression, and 7-ethoxyresorufin O-deethylase activity. A luciferase assay showed that both As(3+) and Hg(2+) inhibited the TCDD-induced activity of gene constructs containing either synthetic 3XRE or a distal cyp1a1 promoter region, implying that the decreased levels of TCDD-induced cyp1a1 were due to transcriptional effects. A proteomic study showed that the toxic effects of As(3+) might be due to changes in cellular metabolic processes, the cellular stimulation response and the cellular redox state in ZFL cells.

Abstract
Cadmium (Cd) is a toxic metal that is hazardous to health, and its exposure showed a significant reduction in mitochondrial phospholipid function in the rat testes. Cd induction enhanced phospholipases (PLA2 s) activities, specifically the secretory PLA2 and cytosolic PLA2 . There was a reduction in mitochondrial membrane potential and significant decline in the respiratory complexes, which was confirmed by 2D blue native gel. The mRNA expression of cyclooxygenase and proinflammatory cytokine genes interleukin (IL)-1, IL-6, tumor necrosis factor-α, inducible nitric oxide synthase, and interferon-γ increased and that of anti-inflammatory cytokine IL-10 reduced with Cd exposure in a time-dependent manner. The gene expression of the proapoptotic factor Bax was elevated, and in parallel, the antiapoptotic factor Bcl2 was down-regulated. Hence, this study explored the testes under Cd toxicity and observed alterations in PLA2 s and mitochondrial membrane composition/function and further explored the impact of these alterations on proinflammation and apoptosis. © 2015 Wiley Periodicals, Inc.

Abstract
Cadmium is a well-known testicular toxicant, and parts of the world population are exposed chronically by inhalation or by food and water intake. Grape products have been highlighted as important sources of bioactive compounds, having anti-inflammatory, anti-oxidant and metal chelating properties. Since maintenance of tissue morphology is essential for testicular sperm development and hence male fertility, we analysed the protective effect of grape juice concentrate (GJC) (G8000(®) ) consumption on testicular morphology in rats exposed to cadmium. Thus, four groups of male Wistar rats (n = 6 per group), 50 days old, ingested either water or G8000(®) (2 g/kg/day) until they had completed one spermatogenic cycle in adult life (136 days old). Cadmium (1.2 mg / kg) was injected intraperitoneally when the animals were 80 days old into one of the water and one of the G8000 groups; intraperitoneal saline was used as a control in the other two groups. Animals anaesthetised and exsanguinated at 136 days and then perfused with Karnovsky's fixative and then the testes were collected for morphological analysis. We describe evident disruption of testicular morphology by cadmium, with alteration in tissue component proportions, reduced Leydig cells volume and initial signs of an inflammatory process. Ultrastructural analysis showed greater damage, suggesting spermatogenesis disruption. G8000(®) ingestion allowed tissue architecture to be re-established, as was corroborated by our stereological and morphometric findings. Animals from the group where G8000(®) had been administered together with cadmium revealed a significant reduction in macrophages and blood vessel volume, suggesting diminished inflammation, when compared to animals that received only cadmium. Moreover, smaller number of ultrastructural alterations was noted, revealing fewer areas of degeneration and disorganized interstitium. In conclusion, our results demonstrate that GJC consumption prevented the spermatogenic disruption promoted by cadmium, and thus could be a promising form of therapy against male infertility.

Abstract
Metallothioneins (MTs) are cysteine-rich, low molecular weight, and heavy metal-binding protein molecules. MT participates in metallic homeostasis and detoxification in living animals due to its abundant cysteine. In order to investigate the functions of MT during spermiogenesis in the mudskipper (Boleophthalmus pectinirostris), we identified the MT complete which contains: an 83bp 5' untranslated region, a 110bp 3' untranslated region, and a 183bp open reading frame. The protein alignment between MT sequences of other species shows a high similarity and a strong identity in cysteine residues vital for the metal-binding affinity of MT. The localizations of MT were mainly in the cytoplasm of germinal cells, indicating a role in spermatogenesis and testis protection. After the cadmium (Cd) exposure, the testis presents abnormal morphology and MT mRNA expression, both of which indicate a sensitive response of testis MT to Cd. Therefore, we suggest that MTs play an important role in spermatogenesis and testes protection against Cd toxicity in B. pectinirostris.

Abstract
Metallothioneins (MTs) are a family of stress proteins that are involved in the process of detoxification and anti-oxidation. Previous studies have focused mostly on the expression and functions of MTs in the non-reproductive tissues of aquatic vertebrates. However, there have been only a few reports regarding the functions of MTs in the reproductive tissues of such vertebrates. In order to investigate the function of MTs during spermatogenesis in Pseudosciaena crocea, reverse-transcription polymerase chain reaction (PCR) and rapid amplification of cDNA ends were performed to obtain the P. crocea MT complete cDNA sequence from the total RNA of the testes for the first time. MT was detected in the liver, kidneys, testes, spleen, gill and muscle of P. crocea by tissue-specific expression analysis. Meanwhile, immunohistochemistry staining indicated that the MT protein was localized in germ cells, Sertoli cells and the peripheral connective tissues in P. crocea testes. Furthermore, acute toxicity tests were conducted with cadmium (Cd) to determine the 96 h-medial lethal concentration value. The toxic effects of Cd on the microstructure and ultrastructure of the testes were observed. In addition, the changes in MT mRNA expression levels in the testes after Cd exposure were measured using real-time quantitative PCR. Consequently, we suggest that MTs play an important role in spermatogenesis and testes protection against Cd toxicity in P. crocea.

Abstract
In humans and other mammals, cadmium (Cd) causes various damages to different organs and tissues of the body. This review presents a comprehensive overview on the effect of Cd on the structure of seminiferous tubules, Leydig cells and blood vessels in the testis. The main observation of the effect of Cd is destruction of the seminiferous tubules with severe necrotic areas. Damage is to all stages of developing germ cells by inducing their structural changes and the apoptotic cell death. Sertoli supporting cells are considered the most vulnerable cells. Their damage results in cytoplasmic rearrangement and disruption of inter-Sertoli tight junctions resulting in increased permeability of the blood-testis barrier, structural changes in the Leydig cells and decreased testosterone secretion. After long time of Cd exposure an increase of the amount of interstitial connective tissue occurs. In blood vessels Cd exposure causes various morphological and physiological changes in vascular endothelial cells and smooth muscle cells. In humans and other mammals, the range of effect depends on the dose, route, ways, and duration of exposure. After necrosis of the sensitive cells Cd produced lesions in surrounding tissue and activate free cells. Atrophy of the seminiferous tubules is followed by Leydig cell regeneration and interstitial revascularization. In birds, spermatogenic cells underwent irreversible degeneration or atrophy of seminiferous tubules in the absence of significant vascular lesions.

Abstract
While the toxicity of metals and metalloids, like arsenic, cadmium, mercury, lead and chromium, is undisputed, the underlying molecular mechanisms are not entirely clear. General consensus holds that proteins are the prime targets; heavy metals interfere with the physiological activity of specific, particularly susceptible proteins, either by forming a complex with functional side chain groups or by displacing essential metal ions in metalloproteins. Recent studies have revealed an additional mode of metal action targeted at proteins in a non-native state; certain heavy metals and metalloids have been found to inhibit the in vitro refolding of chemically denatured proteins, to interfere with protein folding in vivo and to cause aggregation of nascent proteins in living cells. Apparently, unfolded proteins with motile backbone and side chains are considerably more prone to engage in stable, pluridentate metal complexes than native proteins with their well-defined 3D structure. By interfering with the folding process, heavy metal ions and metalloids profoundly affect protein homeostasis and cell viability. This review describes how heavy metals impede protein folding and promote protein aggregation, how cells regulate quality control systems to protect themselves from metal toxicity and how metals might contribute to protein misfolding disorders.

Abstract
Metallothioneins (MTs) are ubiquitous metal-binding, cysteine-rich, small proteins and play a major role in metal homeostasis and/or detoxification in all organisms. In a previous study, a novel full length MT gene was isolated from the freshwater crab (Sinopotamon henanense), a species widely distributed in Shanxi and Henan Provinces, China. In this report, the gene for the crab MT was inserted into a PET-28a-6His-SUMO vector and recombinant soluble MT was over-expressed as fusions with SUMO in Escherichia coli. The recombinant fusion protein was purified by affinity chromatography and its biochemical properties were analyzed. In addition, on the basis of constructing SUMO-MT, two mutants, namely SUMO-MTt1 and SUMO-MTt2, were constructed to change the primary structure of SUMO-MT using site-directed mutagenesis techniques with the amino acid substitutions D3C and S37C in order to increase metal-binding capacity of MT. E. coli cells expressing SUMO-MT and these single-mutant proteins exhibited enhanced metal tolerance and higher accumulation of metal ions than control cells. The results showed that the bioaccumulation and tolerance of Zn(2+), Cu(2+) and Cd(2+) in these strains followed the decreasing order of SUMO-MTt1 > SUMO-MTt2 > SUMO-MT. E. coli cells have low tolerance and high accumulation towards cadmium compared to zinc and copper. These results show that the MT of S. henanense could enhance tolerance and accumulation of metal ions. Moreover, we were able to create a novel protein based on the crab MT to bind metal ions at high density and with high affinity. Therefore, SUMO-MT and its mutants can provide potential candidates for heavy metal bioremediation. This study could help further elucidate the mechanism of how the crab detoxifies heavy metals and provide a scientific basis for environment bioremediation of heavy metal pollution using the over-expression of the crab MT and mutant proteins.

Abstract
Heat shock protein 32 (Hsp32)/heme oxygenase-1 (HO-1) may be a key enzyme for the protection of cells against stress. Its anti-apoptotic effect has been attributed to its product, carbon monoxide (CO), in many types of cells. However, whether its anti-apoptotic mechanism plays a role in Sertoli cells (SCs) is not yet clear. We hypothesise that Hsp32/HO-1 and CO generated from it provide survival advantages in SCs by preventing apoptosis under heat exposure. After treatment of cultured SCs with hyperthermia and/or Hsp32/HO-1 activater hemin, apoptosis was measured valuated by annexin V-FITC and caspase-3 activation. We have also analysed the Hsp32/HO-1-derived CO content of cultured media and cyclic guanosine monophosphate (cGMP) production by enzyme-linked immunosorbent assay (ELISA). Hyperthermia induced SCs apoptosis, while preincubation with hemin suppressed SC hyperthermia-induced apoptosis. Hyperthermia and/or hemin increase Hsp32/HO-1 gene expression and the production of CO, which, in turn, stimulates the generation of cGMP. The results suggest that Hsp32/HO-1 is a protective factor in heat-stressed SCs, and that CO generated from Hsp32/HO-1 is involved in the anti-apoptotic pathway.

Abstract
Abstract
The knowledge of the speciation of elements at trace and ultra-trace level, in biological and environmental media is essential to acquire a better understanding of the mechanisms of toxicity, transport and accumulation in which they are involved. Determining the speciation of an element in a given medium is challenging and requires the knowledge of different methodological approaches: the calculation approach and the experimental approach through the use of dedicated analytical and spectroscopic tools. In this framework, this mini-review reports the approaches to investigate the speciation of elements in biological and environmental media as well as the experimental techniques of speciation analysis, illustrated by recent examples. The main analytical and spectroscopic techniques to obtain structural, molecular, elemental and isotopic information are described. A brief overview of separation techniques coupled with spectrometric techniques is given. Imaging and micro-localisation techniques, which aim at determining the in situ spatial distribution of elements and molecules in various solid samples, are also presented. The last part deals with the development of micro-analytical systems, since they open crucial perspectives to speciation analysis for low sample amounts and analysis on field.

Abstract
Cadmium-induced testicular toxicity is mediated through oxidative stress and inflammation which eventually lead to cell death. Simvastatin, the antihyperlipidemic agent, exhibits additional antioxidant and anti-inflammatory activities. The aim of the present work was to investigate the protective effect of simvastatin against cadmium-induced testicular toxicity in rats. The rats received a single intraperitoneal (i.p.) injection of cadmium chloride (2 mg/kg). Simvastatin treatment (5 mg/kg/day, i.p.) was applied for three consecutive days, starting 1 day before cadmium administration. Cadmium significantly decreased serum testosterone, and testicular reduced glutathione and catalase activity, and significantly increased testicular malondialdehyde, nitric oxide, and cadmium ion levels. Simvastatin significantly ameliorated the biochemical changes induced by cadmium. Cadmium-induced testicular tissue injury observed by histopathological examination was attenuated by simvastatin. In addition, simvastatin significantly decreased the expression of inducible nitric oxide synthase, cyclooxygenase-2, tumor necrosis factor-α, nuclear factor-κB, and caspase-3, and increased heme oxygenase-1 expression in testicular tissue of rats exposed to cadmium toxicity. It was concluded that simvastatin, through its antioxidant and anti-inflammatory activities, provided a significant protective effect against cadmium-induced testicular toxicity in rats. However, starting treatment with simvastatin before cadmium exposure, as done in the present work, is not clinically applicable. Therefore, other investigations are needed to assess the protective effect of simvastatin treatment following induction of cadmium testicular toxicity.

Abstract
The aim of the present study was to investigate the effects of long-term grape juice concentrate (GJC) consumption, in two dosages, on the reproductive parameters of cadmium-exposed male rats. The effects of the concentrate on body mass gain, plasma testosterone levels, reproductive organ weights, daily sperm production, sperm morphology, testis histopathological and histomorphometrical parameters, and testicular antioxidant markers were investigated. Wistar rats (n 54) were distributed into six groups: CdCl2; cadmium and grape juice I (1·18 g/kg per d); cadmium and grape juice II (2·36 g/kg per d); grape juice I (1·18 g/kg per d); grape juice II (2·36 g/kg per d); control. A single dose of CdCl2 (1·2 mg/kg body weight (BW)) was injected intraperitoneally and the grape juice was administered orally for 56 d. The results indicated that cadmium changed all reproductive and antioxidant parameters. At dosage I (1·18 g/kg BW), GJC consumption did not show the effects against cadmium-induced damages. In contrast, at dosage II (2·36 g/kg BW), the GJC improved the gonadosomatic index (P= 0·003), serum testosterone levels (P= 0·001), the relative weight of epididymis (P= 0·013) and ventral prostate (P= 0·052), the percentage of normal sperm (P= 0·001), and histopathological and histomorphometrical parameters. In addition, at this dosage, normalisation of the enzymatic activity of superoxide dismutase (P= 0·001) and of testicular levels of glutathione (P= 0·03) were observed. The parameters of the non-exposed rats did not depict significant alterations. In conclusion, the product was able to act as a protector of reproductive function against cadmium-induced damage. Such a property was expressed in a dose-dependent manner as the more effective dose was dosage II. The GJC acted possibly by antioxidant mechanisms.

Abstract
Cadmium (Cd) is an environmental carcinogenic pollutant known to inactivate several proteins involved in DNA repair systems while at the same time creating an oxidative stress that can result in additional DNA lesions. The testis and the lung are the target organs for cadmium carcinogenesis. Increased production of oxidants in vivo can cause damage to intracellular macromolecules such as DNA, proteins and lipids, which in turn lead to oxidative injury. So, this investigation aimed to evaluate the protective role of L-Carnitine through up regulation of HSPs against DNA damage induced by cadmium chloride. The current study was carried out on forty adult male rats, each with average weight 220-250g., were divided into 4 equal groups. 1(st) group was received saline solution (0.5 ml/100 g body weight) and kept as control. 2(nd) group was received 500mg / kg body weight L-Carnitine intraperitoneally (IP). 3(rd) group was administered 1.2 mg cadmium chloride IP. 4(th) group was received both cadmium chloride and L-Carnitine simultaneously. The comet assay parameters showed significantly increased HSP70 and DNA damage in testis cells after 10 and 56 days in the third group. Meanwhile, HSP70 showed significantly decreased levels after 10 days and 56 days in the fourth group after L-Carnitine treatment simultaneously with cadmium chloride. The results of the present study demonstrate a damaging effect of cadmium chloride on DNA of the testis cells (with low stress response). This damaging effect increases the synthesis of HSP70 that upregulated by L-Carnitine treatment and showed ameliorative effect of the cells for recovery.

Abstract
The gene transcript profile responses to metal oxide nanoparticles was studied using human cell lines derived from the colon and skin tumors. Much of the research on nanoparticle toxicology has focused on models of inhalation and intact skin exposure, and effects of ingestion exposure and application to diseased skin are relatively unknown. Powders of nominally nanosized SiO2, TiO2, ZnO and Fe2O3 were chosen because these substances are widely used in consumer products. The four oxides were evaluated using colon-derived cell lines, RKO and CaCo-2, and ZnO and TiO2 were evaluated further using skin-derived cell lines HaCaT and SK Mel-28. ZnO induced the most notable gene transcription changes, even though this material was applied at the lowest concentration. Nano-sized and conventional ZnO induced similar responses suggesting common mechanisms of action. The results showed neither a non-specific response pattern common to all substances nor synergy of the particles with TNF-α cotreatment. The response to ZnO was not consistent with a pronounced proinflammatory signature, but involved changes in metal metabolism, chaperonin proteins, and protein folding genes. This response was observed in all cell lines when ZnO was in contact with the human cells. When the cells were exposed to soluble Zn, the genes involved in metal metabolism were induced but the genes involved in protein refoldling were unaffected. This provides some of the first data on the effects of commercial metal oxide nanoparticles on human colon-derived and skin-derived cells.

Abstract
Basic sperm analysis is limited as a method of estimating pregnancy. This study’s objective was use of microarray technology to differentiate the gene expressions of spermatozoa that achieved pregnancy in an intracytoplasmic sperm injection (ICSI)cycle in an oocyte donation programme with those that did not achieve pregnancy. A study of nested cases and controls was designed to evaluate fresh and frozen spermatozoa from infertile males undergoing ICSI with donor oocytes. The global genome expression of pooled samples from each group (achieving pregnancy versus those that didn’t, from fresh or frozen spermatozoa)was compared using microarray analysis. The level of expression of some of the transcripts from fresh spermatozoa was shown to differ for those that achieved pregnancy versus those that didn’t. Additionally, exclusively expressed transcripts were identified for both outcome groups. Analysis of frozen spermatozoa didn’t reveal differential expression, but exclusively expressed transcripts were detected. Lists of the transcripts were systematically analysed using different databases in order to provide information about them and their relationship with male fertility. The results revealed profound differences between the expression profiles of spermatozoa that resulted in pregnancy versus those that didn’t. These differences may explain ICSI failure associated with male factor infertility.

Abstract
OBJECTIVE Very little information is known about the toxic effects of cadmium on somatic cells in mammalian testis. The objective of this study is to explore the toxicity of cadmium on piglet Sertoli cells. METHODS Sertoli cells were isolated from piglet testes using a two-step enzyme digestion and followed by differential plating. Piglet Sertoli cells were identified by oil red O staining and Fas ligand (FasL) expression as assayed by immunocytochemistry and expression of transferrin and androgen binding protein by RT-PCR. Sertoli cells were cultured in DMEM/F12 supplemented with 10% fetal calf serum in the absence or presence of various concentrations of cadmium chloride, or treatment with p38 MAPK inhibitor SB202190 and with cadmium chloride exposure. Apoptotic cells in seminiferous tubules of piglets were also performed using TUNEL assay in vivo. RESULTS Cadmium chloride inhibited the proliferation of Piglet Sertoli cells as shown by MTT assay, and it increased malondialdehyde (MDA) but reduced superoxide dismutase (SOD) and Glutathione peroxidase (GSH-Px) activity. Inhibitor SB202190 alleviated the proliferation inhibition of cadmium on piglet Sertoli cells. Comet assay revealed that cadmium chloride caused DNA damage of Piglet Sertoli cells and resulted in cell apoptosis as assayed by flow cytometry. The in vivo study confirmed that cadmium induced cell apoptosis in seminiferous tubules of piglets. Transmission electronic microscopy showed abnormal and apoptotic ultrastructure in Piglet Sertoli cells treated with cadmium chloride compared to the control. CONCLUSION cadmium has obvious adverse effects on the proliferation of piglet Sertoli cells and causes their DNA damage, cell apoptosis, and aberrant morphology. This study thus offers novel insights into the toxicology of cadmium on male reproduction.

Abstract
Cisplatin is a key chemotherapeutic agent for the treatment of esophageal cancer. We examined the intracellular localization of cisplatin in esophageal cancer cell lines and determined their sensitivity to cisplatin using in-air micro-PIXE (particle induced X-ray emission). Two human esophageal squamous cell carcinoma (ESCC) cell lines, TE-2 and TE-13, were examined for their response to cisplatin using MTT assay, flow cytometry, and DNA fragmentation assays. Real-time reverse transcription-polymerase chain reaction was also used to evaluate the mRNA expression of multidrug resistance protein 2 (MRP2) in both cell lines. Platinum localizations of intracellular and intranuclear were measured using in-air micro-PIXE. TE-2 cells were more sensitive to cisplatin than TE-13 cells (IC(50): 37.5 mum and 56.3 mum, respectively). Flow cytometry analysis confirmed that more TE-2 than TE-13 cells were in the sub-G1 phase. DNA fragmentation assay was analyzed to confirm the MTT assay and flow cytometry results. The expression of MRP2 mRNA in TE-13 cells was stronger than in TE-2 cells. In-air micro-PIXE showed that TE-2 cells had higher intracellular cisplatin concentrations than TE-13 cells and the ratio of intranuclear to intracellular cisplatin in individual cells was not significantly different. We observed the intracellular and intranuclear localization of cisplatin using in-air micro-PIXE. The results of this study suggest that in-air micro-PIXE could be a useful quantitative method for evaluating the cisplatin sensitivity of individual cells. Finally, we speculate that MRP2 in the cell membrane may play an important role in regulating the cisplatin sensitivity of ESCC cells.

Abstract
The direct detection of biologically relevant metals in single cells and of their speciation is a challenging task that requires sophisticated analytical developments. The aim of this article is to present the recent achievements in the field of cellular chemical element imaging, and direct speciation analysis, using proton and synchrotron radiation X-ray micro- and nano-analysis. The recent improvements in focusing optics for MeV-accelerated particles and keV X-rays allow application to chemical element analysis in subcellular compartments. The imaging and quantification of trace elements in single cells can be obtained using particle-induced X-ray emission (PIXE). The combination of PIXE with backscattering spectrometry and scanning transmission ion microscopy provides a high accuracy in elemental quantification of cellular organelles. On the other hand, synchrotron radiation X-ray fluorescence provides chemical element imaging with less than 100 nm spatial resolution. Moreover, synchrotron radiation offers the unique capability of spatially resolved chemical speciation using micro-X-ray absorption spectroscopy. The potential of these methods in biomedical investigations will be illustrated with examples of application in the fields of cellular toxicology, and pharmacology, bio-metals and metal-based nano-particles.
