Abstract
Epidemiological and animal studies have supported the carcinogenicity of hexavalent chromium [Cr(VI)]; however, molecular changes responsible for the induction of cancer by Cr(VI) are not entirely understood. Numerous mechanistic studies suggested the role of oxidative stress and genotoxicity in Cr(VI)-mediated carcinogenesis; however, specific types of DNA damage have not yet been conclusively attributed to specific chromium species or other reactive byproducts generated in biological systems exposed to Cr(VI). Due to the remarkably complex chemistry and biological effects of chromium species generated through the intracellular reduction of Cr(VI), their relevance for Cr(VI)-mediated carcinogenesis has not yet been fully elucidated and continues to be a subject of ongoing discussions in the field. In this report, we describe a complex world of chromium species and their reactivity with DNA and other biologically relevant molecules in vitro to inform a more complete understanding of Cr(VI)-mediated toxicity. In addition, we discuss previous results in the context of in vitro models and analytical methods to reconcile some conflicting findings on the biological role of chromium species.

Parikh RY, Gangaraju VK. Hexavalent chromium-induced epigenetic instability and transposon activation lead to phenotypic variations and tumors in Drosophila. ENVIRONMENTAL EPIGENETICS 2022; 9:dvac030.

Abstract
Developmental robustness represents the ability of an organism to resist phenotypic variations despite environmental insults and inherent genetic variations. Derailment of developmental robustness leads to phenotypic variations that can get fixed in a population for many generations. Environmental pollution is a significant worldwide problem with detrimental consequences of human development. Understanding the genetic basis for how pollutants affect human development is critical for developing interventional therapies. Here, we report that environmental stress induced by hexavalent chromium, Cr(VI), a potent industrial pollutant, compromises developmental robustness, leading to phenotypic variations in the progeny. These phenotypic variations arise due to epigenetic instability and transposon activation in the somatic tissues of the progeny rather than novel genetic mutations and can be reduced by increasing the dosage of Piwi - a Piwi-interacting RNA-binding protein, in the ovary of the exposed mother. Significantly, the derailment of developmental robustness by Cr(VI) exposure leads to tumors in the progeny, and the predisposition to develop tumors is fixed in the population for at least three generations. Thus, we show for the first time that environmental pollution can derail developmental robustness and predispose the progeny of the exposed population to develop phenotypic variations and tumors.

Abstract
An oxo(corrolato)chromium(v) complex selectively kills leukemia cells. However, this complex did not induce cell death in primary non-cancer cells. It has been observed that oxo(corrolato)chromium(v) complex induced cell death is associated with DNA damage. Interestingly, the DNA in primary cells largely remained unaffected. DNA isolated from normal and cancerous cell lines also follows similar trends. A chemical reductant, DTT, was used to probe the mechanism of DNA damage. However, it does not show any additive effect on DNA damage.

Abstract
The photochemical products of dinucleotides 5'-TpG/5'-GpT with a photoactivatable anticancer Pt(IV) complex (trans,trans,trans-[Pt(N3)2(OH)2(py)2], py = pyridine; 1) were characterized by electrospray ionization mass spectrometry. The primary MS showed the main products were monoplatinated and diplatinated adducts for both the dinucleotides accompanied by the formation of minor triplatinated dinucleotides, indicating that T-N3 and G-N1 may be platination sites additional to the well-known G-N7 site. Surprisingly, a series of minor platinated adducts with oxidation of guanine and/or thymine were observed. Although guanine is more sensitive to oxidation than thymine, thymine can compete with guanine for complex 1-induced oxidation, of which the oxidation adducts were identified as cis- and trans-diastereomers of 5,6-dihydroxy-5,6-dihydrothymidine (cis,trans-ThdGly), 5-formyl-2'-deoxyuridine (5-FormdUrd), and 5-(hydroxymethyl)-2'-deoxyuridine (5-HMdUrd), respectively. While for guanine, apart from 8-hydroxyguanine (8-OH-G) and N-formylamidoiminohydantoin (RedSp), other guanine oxidized adducts such as spiroiminodihydantoin (Sp), dehydroguanidinohydantoin (DGh), and 2,6-diamino-4-hydroxy-5-formamidopyrimidine (FapyG) were also identified. MS/MS analysis showed that unique fragments with a Pt moiety [Pt(N3)(py)] cross-linking the G and T bases were formed during the fragmentation of monoplatinated dinucleotides. Such binding mode to and oxidative damages on DNA bases imposed by the diazido Pt(IV) complex are apparently distinct from those of cisplatin, perhaps accounting for its unique mechanism of action.

Abstract
Hexavalent chromium (Cr[VI]) is associated with occupational lung cancer and poses a significant public health concern. When exposed to Cr[VI], cells rapidly internalize this compound and metabolize it to Cr[III]. Byproducts of Cr[VI] metabolism include unstable Cr[V] and Cr[IV] intermediates that are believed to be directly responsible for the genotoxicity and carcinogenicity caused by Cr[VI] exposure; however, the carcinogenic potential of the Cr intermediates and the mechanisms of Cr-induced carcinogenesis remain to be further defined. Utilizing synthetic Cr[IV] and Cr[V] compounds, we demonstrate here that Cr[IV] or Cr[V] exposure induces DNA double-strand breaks; however, of the two compounds, mammalian cells only respond to Cr[V]-induced DNA damage. Exposure to Cr[V], but not Cr[IV], results in initiation of cell cycle checkpoints and activates the ATM kinase, a critical regulator of the DNA damage response. Furthermore, cells exposed to Cr[IV] have significantly increased mutation frequencies in the HPRT gene compared to cells exposed to Cr[V], indicating that Cr[IV] possesses a higher mutagenic potential than Cr[V]. We also find that MLH1, a critical mismatch repair (MMR) protein, is required for activation of the G2/M cell cycle checkpoint in response to Cr[VI] exposure and to limit Cr-induced mutagenesis. Our results provide evidence for Cr[IV] as the ultimate mutagenic intermediate produced during Cr[VI] metabolism and indicate that functional MMR is crucial in the cellular response to chromium exposure.

Abstract
2-Deoxyribonolactone lesions were identified as major products of radiation damage to DNA mediated by o,o'-diphenyleneiodonium cations in a hydroxyl radical-scavenging environment. The highest selectivity toward deoxyribonolactone formation (up to 86% of all sugar-phosphate damages) and the overall reaction efficiency (up to 40% of all radiation-generated intermediates converted into products) was displayed by derivatives with positively charged (2-aminoethylthio)acetylamino and (2-aminoethylamino)acetylamino side chains. The reaction can be useful for random single-step incorporation of deoxyribonolactone lesions into single- and double-stranded oligonucleotides and highly polymerized DNA directly in commonly used buffers (PBS, phosphate, Tris-HCl, etc.) at room temperature. In combination with HPLC separation, this technique can serve as a source of short (<6 mer) sequences containing deoxyribonolactone lesions at known positions.

Abstract
The research is to test the damage to DNA of effective microorganisms (EMs) by heavy metal ions As3+, Cd2+, Cr3+, Cu2+, Hg2+, Pb2+, and Zn2+, as well as the effects of EM bacteria on wastewater treatment capability when their DNA is damaged. The approach applied in this study is to test with COMET assay the damage of EM DNA in wastewater with different concentrations of heavy metal ions As3+, Cd2+, Cr3+, Cu2+, Hg2+, Pb2+, Zn2+, as well as the effects of EM treated with As3+, Cd2+, Cr3+, CU2+, Hg2+, Pb2+, and Zn2+ on COD degrading capability in wastewater. The results showed that the damage of the DNA of EM were negatively correlated with their treatment capability and that EM bacteria maximum tolerant concentrations of these heavy metal ions was at 0.05 mg/L for As3+, 0.2 mg/L for Hg2+, 0.5 mg/L for Cd2+, Cr3+, and Cu2+, and 1 mg/L for Pb2+ and Zn2+.

Abstract
The oxidation of methionine (Met) plays an important role during biological conditions of oxidative stress as well as for protein stability. By choosing [oxo(salen)chromium(V)] ions, [(salen)Cr(V)=O](+) (where salen = bis(salicylidene)ethylenediamine) as suitable biomimics for the peptide complexes that are formed during the reduction of Cr(VI) with biological reductants, the oxidation of methionine and substituted methionines with five [oxo(salen)chromium(V)] complexes in aqueous acetonitrile has been investigated by spectrophotometric, electron paramagnetic resonance (EPR) spectroscopy and electrospray ionization mass spectrometry (ESI-MS) methods. In aqueous solution [(salen)Cr(V)=O](+) ion is short lived, ligation of H(2)O to the Cr center takes place and [O=Cr(V)(salen)-H(2)O](+) adduct is the active oxidant. The reaction is found to be first order each in the oxidant and the substrate. The presence of water in the reaction system accelerates the reaction rate and an inactive, stable mu-oxo dimer is also formed during the course of the reaction. On the basis of spectral, kinetic and product analysis study a mechanism involving direct oxygen transfer from [O=Cr(V)(salen)-H(2)O](+) to methionine has been proposed as a suitable mechanism for the reaction.

Abstract
The Cr(V) complexes, bis(2-ethyl-2-hydroxybutyrato)oxochromate(V) ([OCr(V)(ehba)(2)](-)) and (2,2-bis(hydroxymethyl)-2-(bis(2-hydroxyethyl)amino)ethanolato)oxochromate(V) ([OCr(V)(BT)](2-)), were reacted with a series of deoxyribonucleotide triphosphates. Oxidation of deoxyribose at C4' was observed by measuring the amount of thiobarbituric acid reactive species (TBARS) produced in these reactions. For both compounds, the TBARS obtained with purine nucleotides was between 2.25 and 3.5 times greater than what was observed with pyrimidine nucleotide. This result suggests that the identity of the nucleic acid base can influence the hydrogen atom abstraction at C4'. Overall, the amount of product obtained with [OCr(V)(BT)](2-) was significantly less than what was observed with [OCr(V)(ehba)(2)](-), indicating that these two Cr(V) model complexes may oxidize DNA differently.

Abstract
Evidence for the non-enzymatic phosphorylation of bovine serum albumin (BSA) by sodium bis(2-ethyl-2-hydroxybutyrato)oxochromate(V), Na[CrVO(ehba)2], 1, sodium bis(2-hydroxy-2-methylbutyrato)oxochromate(V), Na[CrVO(hmba)2], 2 and potassium dichromate, K2Cr2O7, 3 in the presence of labeled adenosine-5'-triphosphate (ATP) under conditions of physiological pH is presented. Aggregation and extent of phosphorylation of BSA mediated by 1, 2 or 3 seems to increase with the concentration and time of incubation of the reaction mixture containing all the reactants. The [gamma-32P] label in ATP is incorporated into aggregates of BSA in the in vitro reaction of the protein with ATP in the presence of 1, 2 or 3. Phosphorylation of BSA by ATP in the absence of 1, 2 or 3 is negligible. Addition of EDTA reverses aggregation of protein and liberates partially the incorporated phosphate label. The stoichiometry of phosphorylation is found to be the highest and is equal to 12.25 mol PO4(3-)/mol BSA in the presence of 500 microM of 1, which decreases to 10.56 mol PO4(3-)/mol BSA after EDTA treatment. Resistance to the removal of phosphate label by EDTA increases with increase in time of incubation. Dialysis of phosphorylated BSA reverses the incorporated [gamma-(32)P] label only partially, indicating the formation of covalent links of phosphate groups to BSA. Evidence for the site of phosphorylation in the reaction mediated by 1, 2 or 3 being hydroxyl side groups of tyrosine and serine/threonine residues has been gained. Based on the results, a possibility that 1, 2 and 3 mimic the function of tyrosine and serine/threonine kinases has been invoked.

Abstract
Release of 5-methylene-2-furanone (5-MF), a characteristic marker of DNA deoxyribose oxidative damage at the C1' position, was observed in significant quantities from X-irradiated DNA. This observation, which held for DNA irradiated either in aqueous solution or as a film, requires postirradiation treatment at 90 degrees C in the presence of polyamines and divalent metal cations at biological pH. The 5-MF product was quantified by using reverse-phase HPLC. The radiation chemical yield of 5-MF comprised more than 30% of the yield of total unaltered base release. Polylysine, spermine and Be(II) showed the strongest catalytic effect on 5-MF release, while Zn(II), Cu(II), Ni(II), putrescine and Mg(II) were substantially less efficient. We have hypothesized that the 5-MF release from irradiated DNA occurs through catalytic decomposition of the 2'-deoxyribonolactone (dL) precursor through two consecutive beta- and delta-phosphate elimination reactions. A stepwise character of the process was indicated by the S-shaped time course of 5-MF accumulation. If dL proves to be the precursor to 5-MF formation, it would then follow that dL is a very important lesion generated in DNA by ionizing radiation.

Abstract
Mechanistic insights into Cr(VI)-induced carcinogenicity and possible implication of Cr(V) species formed by the redox reactions of chromium-bearing species have attracted interest. We have previously demonstrated that when human peripheral blood lymphocytes are exposed to the Cr(V) complexes, viz., sodium bis(2-ethyl-2-hydroxybutyrato)oxochromate(V), Na[Cr(V)O(ehba)(2)] and sodium bis(2-hydroxy-2-methylbutyrato)oxochromate(V), Na[Cr(V)O(hmba)(2)], apoptosis and formation of reactive oxygen species (ROS) are observed. The molecular mechanisms involving cellular signaling pathways leading to apoptosis are addressed in the present study. Treatment of lymphocytes with Na[Cr(V)O(ehba)(2)] and K(2)Cr(2)O(7) leads to the activation of the Src-family protein tyrosine kinases namely, p56(lck), p59(fyn), and p56/53(lyn), which then activates caspase-3, both of which are under the partial influence of ROS. Inhibition of the Src-family tyrosine kinases activity by PP2 and of caspase-3 by Z-DEVD-FMK reverses apoptosis, thereby suggesting their importance. Antioxidants only partially reverse the apoptosis induced by Cr(VI/V), suggesting that pathways other than those induced by ROS cannot be ruled out. Although the complex, Na[Cr(V)O(ehba)(2)] is known to be relatively stable in aqueous solutions, previous studies have shown that the Cr(V) complex, Na[Cr(V)O(ehba)(2)] disproportionates to Cr(VI) and Cr(III) forms at pH 7.4 through complex mechanistic processes. Dynamics studies employing EPR data show that the Cr(V) state in Na[Cr(V)O(ehba)(2)] is relatively more stable in RPMI-1640 medium containing plasma. Formation of ROS during the reaction of redox partners with Na[Cr(V)O(ehba)(2)] is an early event and compares favorably in kinetic terms with the reported rate processes for disproportionation. This investigation presents evidence for the direct implication of Cr(V) in Cr(VI)-induced apoptosis of lymphocytes.

Abstract
Cr(VI) compounds have been declared as a potent occupational carcinogen by IARC (1990) through epidemiological studies among workers in chrome plating, stainless-steel, and pigment industries. Studies relating to the role of intermediate oxidation states such as Cr(V) and Cr(IV) in Cr(VI)-induced carcinogenicity are gaining importance. In this study, issues relating to toxicity elicited by Cr(V) have been addressed and comparisons made with those relating to Cr(VI) employing human peripheral blood lymphocytes. Lymphocytes have been isolated from heparinized blood by Ficoll-Hypaque density gradient centrifugation and exposed to Cr(V) complexes viz. sodium bis(2-ethyl-2-hydroxybutyrato)oxochromate(V), Na[Cr(V)O(ehba)(2)], 1 and sodium bis(2-hydroxy-2-methylbutyrato)oxochromate(V), Na[Cr(V)O(hmba)(2)], 2 and Cr(VI). The phytohemagglutinin (PHA)-induced proliferation of lymphocytes has been found to be inhibited by the two complexes of Cr(V) and chromate Cr(VI) in a time- and concentration-dependent manner. Viability of cells decreases in the presence of Cr(V). Apoptosis appears to be the mode of cell death in the presence of both Cr(V) and Cr(VI). Pretreatment of cells with antioxidants before exposure to chromium(V) complexes reverse apoptosis partially. Possibility for the formation and implication of reactive oxygen species in Cr(V)-induced apoptosis of human lymphocyte cells has been indicated in this investigation. The intermediates of Cr(V) and radical species in the biotoxic pathways elicited by Cr(VI) seems feasible.

Abstract
The induction of genotoxicity by Cr (VI) is dependent on its reductive activation inside the cell. Our recent studies have found that reduction of Cr (VI) by cysteine resulted in the formation of mutagenic Cr (III)-DNA adducts in the absence of oxidative DNA damage. In this work, we examined the formation of oxidative and Cr (III)-dependent types of DNA damage under a broader range of Cr (VI) and cysteine concentrations and investigated a potential role of this reducer in intracellular metabolism of Cr (VI). Peripheral lymphocytes from unexposed humans had 7.8-fold excess of glutathione over cysteine, whereas lymphocytes from stainless steel welders contained only 3 times higher amount of glutathione (p = 0.0009) which was entirely caused by the decrease in the concentration of glutathione. A strong correlation (r = 0.72) between the levels of both thiols was found in lymphocytes from controls. The number of DNA-protein crosslinks in lymphocytes from welders was 4.1 times higher than among controls, indicating the presence of Cr (VI)-dependent DNA damage. The average rate of Cr (VI) reduction by cysteine was approximately 5 times faster than that by glutathione. Higher reduction rate combined with the decrease in the intracellular concentration of glutathione should make cysteine a predominant Cr (VI)-reducing thiol in lymphocytes of welders. Analysis of the initial rates of Cr (VI) reduction by different concentrations of cysteine suggested the presence of one- and two-electron pathways, with one-electron mechanism dominating in the physiological range of concentrations. There was no detectable formation of DNA breaks or abasic sites under a broad range of Cr (VI) and cysteine concentrations, resulting in up to 68-fold differences in the rates of reduction and the production of as many as 3 Cr (III)-DNA adducts per 10 bp. The reactions with slow reduction rates (low concentrations of cysteine) led to the most extensive formation of Cr (III)-DNA adducts. In summary, these results further establish Cr (III)-DNA adducts as the major form of DNA damage resulting from Cr (VI) metabolism by cysteine. The role of cysteine in reduction of Cr (VI) becomes more significant under conditions of occupational exposure to Cr (VI)-containing welding fumes.

Abstract
Small particles of metallic tungsten, known also as tungsten microprojectiles, are routinely used for biotechnological purposes. In such applications, tungsten was observed to affect the integrity of plasmid DNA. Here we present evidence that interaction between tungsten particles and intact circular plasmids pU19, pUC119, and ColE1 may result in generation of a limited number of single-strand DNA breaks. As a consequence, supercoiled DNA is converted into its open circular form and no fragmentation products can be detected. The rate of the tungsten-mediated reaction depends on pH but is not influenced by ascorbate, Tris, or EDTA. No DNA nicking can be observed when the tungsten particles are replaced by substances that can be leached out from these particles with water or incubation buffers. Likewise, commercial sodium tungstate, tungsten (VI) oxide, and tungsten (VI) chloride and products of its decomposition remain DNA undamaged. Native plasmid DNA molecules, upon adsorption on the surface of tungsten microparticles, may undergo some nicking without a need for participation of external catalysts.
