Maternal overnutrition before and during pregnancy induces DNA damage in male offspring: A rabbit model. Mutat Res 2021; 865:503324.

Abstract
Using a rabbit model, we investigated whether maternal intake of a high-fat and high-carbohydrate diet (HFCD) before and during pregnancy induces an increase in micronuclei frequency and oxidative stress in offspring during adulthood. Female rabbits received a standard diet (SD) or HFCD for two months before mating and during gestation. The offspring from both groups were nursed by foster mothers fed SD until postnatal day 35. After weaning, all the animals received SD until postnatal day 440. At postnatal day 370, the frequency of micronuclei in peripheral blood reticulocytes (MN-RETs) increased in the male offspring from HFCD-fed mothers compared with the male offspring from SD-fed mothers. Additionally, fasting serum glucose increased in the offspring from HFCD-fed mothers compared with the offspring from SD-fed mothers. At postnatal day 440, the offspring rabbits were challenged with HFCD or continued with SD for 30 days. There was an increase in MN-RET frequency in the male rabbits from HFCD-fed mothers, independent of the type of challenging diet consumed during adulthood. The challenge induced changes in serum cholesterol, LDL and HDL that were influenced by the maternal diet and offspring sex. We measured malondialdehyde in the liver of rabbits as an oxidative stress marker after diet challenge. Oxidative stress in the liver only increased in the female offspring from HFCD-fed mothers who were also challenged with this same diet. The data indicate that maternal overnutrition before and during pregnancy is able to promote different effects depending on the sex of the animals, with chromosomal instability in male offspring and oxidative stress and hypercholesterolemia in female offspring. Our data might be important in the understanding of chronic diseases that develop in adulthood due to in utero exposure to maternal diet.

Abstract
The European sturgeon, Acipenser sturio, is a highly endangered species that almost disappeared in the last decades. Thanks to yearly restocking of the population, this species is still found in the Gironde estuary (France), where juveniles grow during several years before leaving to the ocean. The aims of this study were to evaluate the pressure exerted on these fish by known organic and inorganic contaminants during their stay at the Gironde estuary, and to get information on the fish's health in this context. Monthly captures over the year 2014 provided 87 fish from the cohorts 2012 and 2013 mainly, and from cohorts 2008, 2009, and 2011, all fish born in hatchery. We report the very first analyses of contaminant levels and of biological markers measured in the blood of these fish. Low inorganic contamination was found, composed of seven metals mainly Zn (< 5 μg mL-1), Fe (< 1.5 μg mL-1), Cu (< 0.8 μg mL-1), Se (< 0.8 μg mL-1), As (< 0.25 μg mL-1), Co (< 0.14 μg mL-1), and Mn (< 0.03 μg mL-1). Concerning persistent organic contaminants, the sum of seven PCBs varied from 1 to 10 ng g-1 plasma, that of eight OCPs from 0.1 to 1 ng g-1, and that of eight PBDEs from 10 to 100 pg g-1. Higher levels of contaminants were measured during spring as compared to summer. The sex steroid hormone plasma levels (estradiol, testosterone, and 11-ketotestosterone) were quite low, which was predictable for juveniles. The transcription of reproduction-involved genes (EstR, AR, LHR, sox9) in blood cells was demonstrated for the first time. Some of them were correlated with organic contaminant levels PCBs and OCPs. Other gene transcriptions (sodCu and bax) were correlated with PCBs and OCPs. However, the DNA damage level measured here as comet tail DNA and micronuclei ratio in red blood cells were in the very low range of the values commonly obtained in fish from pristine areas. The data presented here can serve as a reference base for future monitoring of this population of sturgeons.

Abstract
Human embryonic kidney 293T cells (HEK293T cells) before and after treatment with silver nanoparticles (AgNPs) were measured using advanced atomic force microscopy (AFM) force measurement technique, and the biomechanical property of cells was analyzed using a theoretical model. The biomechanical results showed that the factor of viscosity of untreated HEK293T cells reduced from 0.65 to 0.40 for cells exposure to 40 μg/mL of AgNPs. Comet assay indicated that significant DNA damage occurred in the treated cells, measured as tail DNA% and tail moment. Furthermore, gene expression analysis showed that for the cells treated with 40 μg/mL of AgNPs, the antiapoptosis genes Bcl2-t and Bclw were, respectively, downregulated to 0.65- and 0.66-fold of control, and that the proapoptosis gene Bid was upregulated to 1.55-fold of control, which indicates that apoptosis occurred in cells exposed to AgNPs. Interestingly, excellent negative correlations were found between the factor of viscosity and tail DNA%, and tail moment, which suggest that the biomechanical property can be correlated with genotoxicity of nanoparticles on the cells. Based on the above results, we conclude that (1) AgNPs can lead to biomechanical changes in HEK293T cells, concomitantly with biological changes including cell viability, DNA damage, and cell apoptosis; (2) the factor of viscosity can be exploited as a promising label-free biomechanical marker to assess the nanotoxicity of nanoparticles on the cells; and (3) the combination of AFM-based mechanical technique with conventional biological methods can provide more comprehensive understanding of the nanotoxicity of nanoparticles than merely by using the biological techniques.

Cytogenetic damage analysis in mice chronically exposed to low-dose internal tritium beta-particle radiation. Oncotarget 2018; 9:27397-27411.

Abstract
The aim of this study was to carry out a comprehensive examination of potential genotoxic effects of low doses of tritium delivered chronically to mice and to compare these effects to the ones resulting from equivalent doses of gamma-irradiation. Mice were chronically exposed for one or eight months to either tritiated water (HTO) or organically bound tritium (OBT) in drinking water at concentrations of 10 kBq/L, 1 MBq/L or 20 MBq/L. Dose rates of internal β-particle resulting from such tritium treatments were calculated and matching external gamma-exposures were carried out. We measured cytogenetic damage in bone marrow and in peripheral blood lymphocytes (PBLs) and the cumulative tritium doses (0.009 - 181 mGy) were used to evaluate the dose-response of OBT in PBLs, as well as its relative biological effectiveness (RBE). Neither tritium, nor gamma exposures produced genotoxic effects in bone marrow. However, significant increases in chromosome damage rates in PBLs were found as a result of chronic OBT exposures at 1 and 20 M Bq/L, but not at 10 kBq/L. When compared to an external acute gamma-exposure ex vivo, the RBE of OBT for chromosome aberrations induction was evaluated to be significantly higher than 1 at cumulative tritium doses below 10 mGy. Although found non-existent at 10 kBq/L (the WHO limit), the genotoxic potential of low doses of tritium (>10 kBq/L), mainly OBT, may be higher than currently assumed.

Abstract
The aim of the present study was to investigate the protective effects of yak-activated protein on hematopoiesis and cytokine function in radiation-induced injury in mice. A total of 180 Kunming mice were randomly divided into three groups (A, B and C). Of these, 60 were randomly divided into a normal control group, a radiation model group, a positive control group and 3 yak-activated protein groups (high, medium and low dose groups; 10, 5 and 2.5 mg/kg, respectively). The other 120 mice were used for the subsequent experiments on days 7 and 14 following radiation. Yak-activated protein was administered orally to mice in the treatment groups and an equal volume of saline was administered orally to mice in the normal control and radiation model groups for 14 days. The positive control group received amifostine (150 mg/kg) via intraperitoneal injection. With the exception of the control group, the groups of mice received a 5 Gy quantity of X-radiation evenly over their whole body once. Changes in the peripheral hemogram, thymus and spleen indices, DNA content in the bone marrow, interleukin (IL)-2 and IL-6 levels, and the expression levels of B cell lymphoma 2 (Bcl-2) and Bcl-2-associated X protein (Bax) following irradiation were assessed. The low dose of yak-activated protein significantly increased Spleen indices in mice 14 days after irradiation and the high and middle dose of yak-activated protein significantly increased Thymus indices in mice 14 days after irradiation (P<0.05) compared with the control group. In addition, hemogram results increased gradually in the low-yak-activated protein dose group and were significantly higher 7 days after irradiation compared with the radiation model group (P<0.05). The DNA content in the bone marrow was markedly increased in the yak-activated protein groups, and increased significantly in the low dose group at 7 days post-irradiation compared with the radiation model group (P<0.05). The IL-2 content was significantly increased in the yak-activated protein groups (P<0.05). Furthermore, Bcl-2 expression was increased and Bax expression was decreased (P<0.05). These results suggest that yak-activated protein exerts protective effects against radiation-induced injury in mice. The optimal effects of yak-activated protein were observed in the medium dose group 14 days after irradiation.

Abstract
Immunosuppressive drugs such as Mycophenolate Mofetil (MMF) are used to suppress the immune system activity in transplant patients and reduce the risk of organ rejection. The present study investigates whether the potential cytotoxicity and genotoxicity varied according to MMF dosing-time in Wistar Rat. A potentially toxic MMF dose (300 mg/kg) was acutely administered by the i.p. route in rats at four different circadian stages (1, 7, 13 and 19 hours after light onset, HALO). Rats were sacrificed 3 days following injection, blood and bone marrow were removed for determination of cytotoxicity and genotoxicity analysis. The genotoxic effect of this pro-drug was investigated using the comet assay and the micronucleus test. Hematological changes were also evaluated according to circadian dosing time. MMF treatment induced a significant decrease at 7 HALO in red blood cells, in the hemoglobin rate and in white blood cells. These parameters followed a circadian rhythm in controls or in treated rats with an acrophase located at the end of the light-rest phase. A significant, thrombocytopenia was observed according to MMF circadian dosing time. Furthermore, abnormally shaped red cells, sometimes containing micronuclei, poikilocytotic in red cells and hypersegmented neutrophil nuclei were observed with MMF treatment. The micronucleus test revealed damage to chromosomes in rat bone marrow; the comet assay showed significant DNA damage. This damage varied according to circadian MMF dosing time. The injection of MMF in the middle of the dark-activity phase produced a very mild hematological toxicity and low genotoxicity. Conversely, it induced maximum hematological toxicity and genotoxicity when the administration occurred in the middle of the light-rest phase, which is physiologically analogous to the end of the activity of the diurnal phase in human patients.

Abstract
The protective effect of Lycium ruthenicum Murr. against radiation injury was examined in mice. Kunming mice were randomly divided into a control group, model group, positive drug group and L. ruthenicum high dose (8 g/kg), L. ruthenicum middle dose (4 g/kg), L. ruthenicum low dose (2 g/kg) treatment groups, for which doses were administered the third day, seventh day and 14th day after irradiation. L. ruthenicum extract was administered orally to the mice in the three treatment groups and normal saline was administered orally to the mice in the control group and model group for 14 days. The positive group was treated with amifostine (WR-2721) at 30 min before irradiation. Except for the control group, the groups of mice received a 5 Gy quantity of X-radiation evenly over their whole body at one time. Body weight, hemogram, thymus and spleen index, DNA, caspase-3, caspase-6, and P53 contents were observed at the third day, seventh day, and 14th day after irradiation. L. ruthenicum could significantly increase the total red blood cell count, hemoglobin count and DNA contents (p < 0.05). The spleen index recovered significantly by the third day and 14th day after irradiation (p < 0.05). L. ruthenicum low dose group showed a significant reduction in caspase-3 and caspase-6 of serum in mice at the third day, seventh day, and 14th day after irradiation and L. ruthenicum middle dose group experienced a reduction in caspase-6 of serum in mice by the seventh day after irradiation. L. ruthenicum could decrease the expression of P53. The results showed that L. ruthenicum had protective effects against radiation injury in mice.
