Abstract
Pyrethroids and its derivatives widespread and uncontrolled continuous use has influenced multiple deleterious effects resulting in as a potential risk factor causing damage to the organ systems. Allethrin and prallethrin are extensively used yet their influences on human primary cells are very limited or under reported. The potential mechanisms by which allethrin and prallethrin modulates human primary cells, especially the molecular mechanisms or interconnectivity of autophagy-apoptosis, their clinical relevance in human subjects or patients are not well defined. In this current study, we've furnished the evidence that both allethrin and prallethrin user samples significantly induced Ccl2 mRNA expression, increased amount of reactive oxygen intermediate, inhibited membrane bound enzymes and altered membrane fluidity. Pyrethroid derivative users had induced levels of lipid peroxidation and induced binding activities of transcription factors(tfs) like CEBP-β and NF-AT. Pyrethroid derivatives induced autophagy, elicited intracellular Ca2+ concentration, calcineurin and regulated proapoptotic genes, DAPK1, Bim. Our current study presumably comprises the initial investigation of a very new mechanism of pyrethroid derivatives-moderated programed cell death in various cell sets or types, like human primary cells where-in this is a late event, is documented. Hence, current research-study might be significant in the various pyrethroid derivatives-allied hematological-related cancers and immunosuppressant or auto-immune disorders. In the foremost instance, we present data stating that pyrethroid derivatives induces multiple cell signaling cascades, like CEBP-β, NF-AT, ERK and MAPK having a role in autophagy thereby; synchronously effectively impact on the apoptosis, therefore causing hematological tumors and toxic or immune related disorders.

Abstract
Odorant-binding proteins (OBPs) play an important role in odour perception and transport in insects. However, little is known about whether OBPs perform other functions in insects, particularly in Apis cerana cerana. Within this study, an OBP gene (AccOBP10) was isolated and identified from A. c. cerana. Both homology and phylogenetic relationship analyses indicated that the amino acid sequence of AccOBP10 had a high degree of sequence identity with other members of the gene family. Analysis of quantitative real-time PCR (qRT-PCR) showed that AccOBP10 mRNA was expressed at higher levels in the venom gland than in other tissues. The mRNA transcript expression of AccOBP10 was upregulated by low temperature (4°C), hydrogen peroxide (H2O2), pyridaben, methomyl and imidacloprid but downregulated by heat (42°C), ultraviolet light, vitamin C, mercuric chloride, cadmium chloride, paraquat and phoxim. Expression of AccOBP10 under abiotic stress was analysed by western blotting, and the results were consistent with those of qRT-PCR. And as a further study of AccOBP10 function, we demonstrated that knockdown of AccOBP10 by RNA interference could slightly increase the expression levels of some stress-related genes. Collectively, these results suggest that AccOBP10 is mainly involved in the response to stress conditions.

Abstract
Cytochrome P450 monooxygenases (P450s) play significant roles in protecting organisms from abiotic stress damage. Here, we report the sequence and characterization of a P450s gene (AccCYP4AV1), isolated from Apis cerana cerana Fabricius. The open reading frame of AccCYP4AV1 is 1506 base pairs long and encodes a predicted protein of 501 amino acids and 57.84 kDa, with an isoelectric point of 8.67. Real-time quantitative polymerase chain reaction (RT-qPCR) analysis indicated that AccCYP4AV1 is more highly expressed in the midgut than in other tissues. In addition, the highest expression occurs in newly emerged adult workers, followed by the first instar of the larval stage. In addition, the expression of the AccCYP4AV1 was upregulated by low temperature (4 °C), ultraviolet radiation, hydrogen peroxide, paraquat, and dichlorvos treatments. In contrast, AccCYP4AV1 transcription was downregulated by other abiotic stress conditions: exposure to increased temperature (44 °C), deltamethrin, cadmium chloride, and mercury (II) chloride. Moreover, when AccCYP4AV1 was knocked-down by RNA interference, the results suggested that multiple antioxidant genes (AccsHSP22.6, AccSOD2, AccTpx1, and AccTpx4) were downregulated and antioxidant genes AccGSTO1 and AccTrx1 were upregulated. The activity levels of peroxidase and catalase were upregulated in the AccCYP4AV1-knocked-down samples, compared with those in the control groups. These findings suggest that the AccCYP4AV1 protein might be involved in the defense against abiotic stress damage.

Abstract
Pesticides play a pivotal role in controlling pests and disease infestations not only in urban agriculture but also in non-agricultural settings. Several pesticides like herbicides, insecticides, fungicides, rodenticides, etc. are applied unintentionally at higher concentrations even in small urban areas such as lawns, gardens and impermeable surfaces. Consequent to their indiscriminate use, both extensively and intensively, in the urban areas, contamination of pesticides poses a serious threat to the environment, living organisms and food safety. Although the fate and ecological effects of pesticides and their residues have been thoroughly understood in agricultural soils, information available in the literature on the impact of these contaminants in the urban environment is very limited and fragmentary. In fact, the fate and behaviour of pesticide residues in the urban environment are distinct from those in other ecosystems since the soils in urban areas greatly vary in their physico-chemical properties. Development of sustainable and eco-friendly approaches for remediation of even urban soils contaminated with pesticides is therefore greatly warranted. Thus, the present critical review is the first single source that provides updated knowledge on the sources, nature and extent of pesticide pollution in the urban environment, and the ecological and human health effects of pesticides and their residues. The potential of nano-encapsulation of pesticides for their application in urban settings has also been discussed.

Abstract
Ostrinia furnacalis is one of the most important pests on maize. O. furnacalis larvae are frequently exposed to the temperature challenges such as high temperature in summer and cold temperature in winter in the natural environment. High and low temperature stress, like any abiotic stress, impairs the physiology and development of insects. Up to now, there is limited information about gene regulation and signaling pathways related to the high and cold stress response in O. furnacalis. High-throughput sequencing of transcriptome provides a new approach for detecting stress and immune response genes under high and low temperature stresses in O. furnacalis. In the present study, O. furnacalis larvae were treated with the temperature at 8 and 40°C, and the responses of O. furnacalis larvae to the temperature stress were investigated through RNA-sequencing and further confirmation. The results showed that immune responses were up-regulated in larvae by the cold stress at 8°C while some stress response genes, such as HSP family, GST-2, Bax inhibitor and P450, were significantly increased at 40°C. Furthermore, quantitative real time polymerase chain reaction were performed to quantify the expression levels of immune related genes, such as PGRP-LB, antimicrobial peptides, lysozyme, serine protease and stress response genes such as small HSPs and HSP90, and the expression levels of these genes were similar to the RNA-seq results. In addition, the iron storage protein Ferritin was found to be involved in the response to temperature stress, and the changes of total iron concentration in the hemolymph were, in general, consistent with the expression levels of Ferritin. Taken together, our results suggested that the stress response genes were involved in the defense against the heat stress at 40°C, and the immune responses triggered by cold stress might provide protection for larvae from cold stress at 8°C. More interestingly, our results showed that during the responses to temperature stress, the total iron concentration in hemolymph regulated by Ferritin increased, which might help O. furnacalis in surviving the low and high temperature stress.

Abstract
As molecular chaperones, DnaJs play critical roles in maintaining cytoplasmic structure and resisting various stresses. However, the functions of DnaJs in insects are poorly understood. In this study, we identified a DnaJC3 from Apis cerana cerana (AccDnaJC3) and investigated its roles in adverse conditions. Real-time quantitative PCR analysis showed that AccDnaJC3 was highly expressed in muscle and epidermis. In addition, AccDnaJC3 was induced by a variety of stresses, such as 4 °C, 24 °C, 44 °C, H2O2, HgCl2, VC, UV, cyhalothrin, abamectin and emamectin benzoate treatments, whereas it was inhibited by CdCl2 and paraquat treatments. Disc diffusion experiments indicated that overexpression of recombinant AccDnaJC3 enhanced Escherichia coli tolerance to some stress conditions. In contrast to the control group, when AccDnaJC3 was knocked down with RNAi technology, several other antioxidant genes were downregulated, suggesting that AccDnaJC3 may play important roles in stress response. Furthermore, we found that the enzyme activities of superoxide dismutase, peroxidase and catalase were lower in AccDnaJC3-knockdown bees than in control bees. Taken together, these results suggest that AccDnaJC3 may be involved in various stress responses in Apis cerana cerana.

Abstract
Mitogen-activated protein kinase kinases (MKKs) are important components of the MAPK signaling pathways, which play a key role in responding to stress and inflammatory stimuli. Here, a new MKK gene, AccMKK6, was identified and functionally analyzed in Apis cerana cerana. Real-time quantitative PCR (qPCR) and Western blot analysis demonstrated that the AccMKK6 expression level was up-regulated by several environmental stresses. Moreover, the knockdown of AccMKK6 by RNA interference technology altered the expression levels of some antioxidant genes. In addition, the knockdown of AccMKK6 resulted in increased malonyldialdehyde (MDA) concentration and decreased antioxidant-related enzymes activity in honeybees. To explore the MAPK signaling pathways involved in AccMKK6, we identified the transcription factor kayak in A. cerana cerana. We analyzed the interactions of AccMKK6, Accp38b, and Acckayak using the yeast two-hybrid system. AccMKK6 and Acckayak showed similar expression profiles after several stress treatments. In addition, the expression level of Acckayak was significantly increased when AccMKK6 was silenced. Therefore, we speculate that AccMKK6 may be involved in the MAPK cascades, which play a crucial role in counteracting oxidative stress caused by external stimuli.

Abstract
The aim of the current study was to evaluate and compare the toxicities of different types of mosquito repellents i.e. coils, mats and liquid vapors in animal models. Different types of mosquito repellents including liquid vaporizers, coils and mats have been extensively used by the people to get protection from the mosquitoes and diseases associated with them. The active constituents of these repellents include; allethrins, pyrethrins, paraffin and various other derivatives, are well known for their toxicities. Exposure of albino mice to these repellents for 3 h per day over a period of 20 days produced significant toxicological effects on vital body organs including; liver, lungs, kidneys, brain and heart. The order of toxicity of different repellents on nervous and hepatic tissues was found to be: Coil > Liquid > Mat while in renal and cardiac tissues, the coil was again found to be the most toxic one, mat with medium toxicity whereas liquid as least toxic (Coil > Mat > liquid). Lungs tissues are almost equally affected by all the repellants. On the basis of current findings, it has been concluded that exposure to various types of mosquito repellents can be deleterious to health and can cause various health related issues by producing pathological changes in the vital organs.

Abstract
Cytochrome P450s play critical roles in maintaining redox homeostasis and protecting organisms from the accumulation of toxic reactive oxygen species (ROS). The biochemical functions of the P450 family have essentially been associated with the metabolism of xenobiotics. Here, we sequenced and characterized three P450 genes, AccCYP314A1, AccCYP4AZ1, and AccCYP6AS5, from Apis cerana cerana Fabricius; these genes play a critical role in maintaining biodiversity. Quantitative PCR (qPCR) analysis indicated that the three genes were all predominantly expressed in the epidermis (EP), followed by the brain (BR) and midgut (MG). In addition, the highest expression levels were detected in the dark-eyed pupae and adult stages. The three genes were induced by temperature (4°C and 44°C), heavy metals (CdCl2 and HgCl2), pesticides (DDV, deltamethrin, and paraquat) and UV treatments. Furthermore, Western blot analysis indicated that the protein expression levels could be induced by some abiotic stressors, a result that complements the qPCR results. We analyzed the silencing of these three genes and found that silencing these genes enhanced the enzymatic activities of peroxidase (POD) and catalase (CAT). Additionally, we investigated the expression of other antioxidant genes and found that some were upregulated, while others were downregulated, suggesting that the upregulated genes may be involved in compensating for the silencing of AccCYP314A1, AccCYP4AZ1, and AccCYP6AS5. Our findings suggest that AccCYP314A1, AccCYP4AZ1, and AccCYP6AS5 may play very significant roles in the antioxidant defense against damage caused by ROS.

Abstract
BACKGROUND Mosquito coil (MC) emits insecticide upon burning which provides limited protection against lethal mosquito borne diseases. However, apart from killing the insect, toxicities associated with the inhalation of these insecticides poses severe health hazards. However, the use of MC is increasing day by day in third world countries in particular but, yet to receive enough attention of both policy maker and general public. The current study was aimed to assess the MC smoke induced damage of pulmonary and hepatic tissues along with observing the alterations of several blood biochemical parameters in mice model. METHODS A total of twenty four Swiss albino mice were allowed to inhale the smoke of allethrin based MC at different duration per day for 120 days. By the end of treatment period, blood sample was drawn from each mouse and blood biochemical parameters including alanine transaminase (ALT), aspartate transaminase (AST), blood urea nitrogen(BUN), serum total protein, cholesterol, low density lipoprotein (LDL) and triglyceride (TG) were analyzed. Intact lung and liver were collected for histological analysis using standard protocol. RESULTS Biochemical study indicates elevated activity of two hepatic enzymes: ALT (89%), AST (85%), in comparison with the respective control. Increased level of some parameters of lipid profile including cholesterol (36%), LDL (48%) and triglyceride (30%) in smoke inhaled mice is the new finding of this study. On the contrary, the activity of serum total protein and BUN was decreased by 20% and 24%, respectively in inhaled mice. Pulmonary tissue of treated mice shows severe forms of emphysema and hyperplasia, especially in the peripheral region of lung, which is the hallmark of chronic obstructive pulmonary disease (COPD). Histological study of hepatic tissue shows apoptosis mediated damage of hepatocytes along with severe form of necrosis. Infiltration of Inflammatory cells was also observed in both of the organs. CONCLUSION Results from the present studies suggest that chronic exposure of allethrin based MC is responsible factor for severe health complications such as COPD due to the alterations of the key biochemical parameters of blood and histo-organization of lung and liver.

Abstract
Pesticide exposure can induce oxidative stress and cause changes to antioxidant enzymes in living organisms. In the present study, the effects of phoxim (an organophosphorus insecticide) and carbaryl (a carbamate insecticide) on antioxidant enzyme activity and gene expression were investigated in the model organism Caenorhabditis elegans. The results show that phoxim exposure can induce superoxide dismutase (SOD) and catalase (CAT) activities and decrease glutathione peroxidase (GPx) activity at lower concentrations. The expression levels of sod-3, sod-5, ctl-1, gpx-6, and gpx-8 were up-regulated after treatment with phoxim. The mRNA expression levels of sod-5, ctl-1 and gpx-6 were increased approximately 70-, 170- and 130-fold, respectively, in the 0.25mM treatment group compared to the control group. Carbaryl exposure decreased SOD activity and induced CAT and GPx activities. The addition of carbaryl up-regulated the expression of sod-5, ctl-1, ctl-3 and gpx-8. Specifically, ctl-1 expression increased approximately 10-fold, and gpx-8 expression increased <30-fold in the 0.5mM treatment group relative to the control group. The transcript level of sod-5 increased >20-fold, and ctl-3 increased approximately 10-fold in the 1mM treatment group. The functions of the antioxidant enzymes during oxidative stress caused by the two insecticides were investigated using deletion mutants. The LC50 values phoxim for the of sod-3 (tm760), sod-5 (tm1146), ctl-1 (ok1242), ctl-3 (ok2042) and gpx-8 (tm2108) mutant strains were lower than those observed for the N2 strain. The LC50 values of carbaryl for the ctl-1 (ok1242), ctl-3 (ok2042) and gpx-6 (tm2535) deletion mutant strains decreased in comparison to the N2 strain. The results suggest that these two insecticides caused oxidative stress and changed altered the antioxidant enzyme activities and their gene expressions in C. elegans. The sod-3, sod-5, ctl-1, ctl-3, gpx-6, and gpx-8 encoding enzymes may play roles in defending cells from oxidative stress caused by these two insecticides.

Abstract
RNA-binding motif proteins (RBMs) belong to RNA-binding proteins that display extraordinary posttranscriptional gene regulation roles in various cellular processes, including development, growth, and stress responses. Nevertheless, only a few examples of the roles of RBMs are known in insects, particularly in Apis cerana cerana. In the present study, we characterized the novel RNA-binding motif protein 11 from Apis cerana cerana, which was named AccRBM11 and whose promoter sequence included abundant potential transcription factor binding sites that are connected to responses to adverse stress and early development. Quantitative PCR results suggested that AccRBM11 was expressed at highest levels in 1-day postemergence worker bees. AccRBM11 mRNA and protein levels were higher in the poison gland and the epidermis than in other tissues. Moreover, levels of AccRBM11 transcription were upregulated upon all the simulation of abiotic stresses. Furthermore, Western blot analysis indicated that AccRBM11 protein expression levels could be induced under some abiotic stressors, a result that did not completely in agree with the qRT-PCR results. It is also noteworthy that the expression of some genes that connected with development or stress responses were remarkably suppressed when AccRBM11 was silenced, which suggested that AccRBM11 might play a similar role in development or stress reactions with the above genes. Taken together, the data presented here provide evidence that AccRBM11 is potentially involved in the regulation of development and some abiotic stress responses. We expect that this study will promote future research on the function of RNA-binding proteins.

Abstract
Estrogen-related receptor (ERR), which belongs to the nuclear receptor superfamily, has been implicated in diverse physiological processes involving the estrogen signaling pathway. However, little information is available on ERR in Apis cerana cerana. In this report, we isolated the ERR gene and investigated its involvement in antioxidant defense. Quantitative real-time polymerase chain reaction (qPCR) revealed that the highest mRNA expression occurred in eggs during different developmental stages. The expression levels of AccERR were highest in the muscle, followed by the rectum. The predicted transcription factor binding sites in the promoter of AccERR suggested that AccERR potentially functions in early development and in environmental stress responses. The expression of AccERR was induced by cold (4 °C), heat (42 °C), ultraviolet light (UV), HgCl2, and various types of pesticides (phoxim, deltamethrin, triadimefon, and cyhalothrin). Western blot was used to measure the expression levels of AccERR protein. These data suggested that AccERR might play a vital role in abiotic stress responses.

Abstract
Superoxide dismutase (SOD) is a family of enzymes with multiple isoforms that possess antioxidative abilities in response to environmental stresses. Panonychus citri is one of the most important pest mites and has a global distribution. In this study, three distinct isoforms of SOD were cloned from P. citri and identified as cytoplasmic Cu-ZnSOD (PcSOD1), extracellular Cu-ZnSOD (PcSOD2), and mitochondrial MnSOD (PcSOD3). mRNA expression level analysis showed that all three isoforms were up-regulated significantly after exposure to the acaricide abamectin and to UV-B ultraviolet irradiation. In particular, PcSOD3 was up-regulated under almost all environmental stresses tested. The fold change of PcSOD3 expression was significantly higher than those of the two Cu-ZnSOD isoforms. Taken together, the results indicate that abamectin and UV-B can induce transcripts of all three SOD isoforms in P. citri. Furthermore, PcSOD3 seems to play a more important role in P. citri tolerance to oxidative stress.

Abstract
Phospholipid hydroperoxide glutathione peroxidases (PHGPXs) are essential enzymes of the cellular antioxidant defense system during insect-plant interactions. However, little attention has been devoted to the functional characterization of PHGXPs in the whitefly Bemisia tabaci. Here, we report the identification and characterization of two PHGPX genes, designated as BtQ-PHGPX1 and BtQ-PHGPX2 from the Mediterranean species of the B. tabaci complex. Sequence analysis indicated that the length of BtQ-PHGPX1 is of 942 bp with a 729 bp open-reading frame (ORF) encoding 242 amino acids, and BtQ-PHGPX2 is of 699 bp with a 567 bp ORF encoding 188 amino acids. Sequence alignment analysis showed that BtQ-PHGPX1 and BtQ-PHGPX2 shared high similarity with other known PHGPXs. The NVASXCGXT, FPCNQFXXQEPG, and IKWNFXKFLV surrounded the reactive cysteine, glutamine, and tryptophan residues, respectively. Recombinant BtQ-PHGPX1 and BtQ-PHGPX2 were overexpressed in Escherichia coli and purified. quantitative reverse transcription-polymerase chain reaction (qRT-PCR) analysis with whiteflies of different development stages showed that the mRNA levels of BtQ-PHGPX2 were significantly higher in larvae than in other stages. The mRNA levels of BtQ-PHGPX2 were significantly higher than BtQ-PHGPX1 during all the developmental stages. The mRNA levels of BtQ-PHGPX1 and BtQ-PHGPX2 in female adults were relatively higher than in male adults. The expression of BtQ-PHGPX1 and BtQ-PHGPX2 was induced by the insecticide imidacloprid. These results suggest that BtQ-PHGPX1 and BtQ-PHGPX2 may participate in detoxification of oxidative hazards in B. tabaci.

Abstract
Arginine kinases (AK) in invertebrates play the same role as creatine kinases in vertebrates. Both proteins are important for energy metabolism, and previous studies on AK focused on this attribute. In this study, the arginine kinase gene was isolated from Apis cerana cerana and was named AccAK. A 5'-flanking region was also cloned and shown to contain abundant putative binding sites for transcription factors related to development and response to adverse stress. We imitated several abiotic and biotic stresses suffered by A. cerana cerana during their life, including heavy metals, pesticides, herbicides, heat, cold, oxidants, antioxidants, ecdysone, and Ascosphaera apis and then studied the expression patterns of AccAK after these treatments. AccAK was upregulated under all conditions, and, in some conditions, this response was very pronounced. Western blot and AccAK enzyme activity assays confirmed the results. In addition, a disc diffusion assay showed that overexpression of AccAK reduced the resistance of Escherichia coli cells to multiple adverse stresses. Taken together, our results indicated that AccAK may be involved of great significance in response to adverse abiotic and biotic stresses.

Abstract
The present study aimed to evaluate the effect of chronic co-exposure to chlorpyrifos (CPF) and deltamethrin (DLT) on erythrocyte osmotic fragility, lipid peroxidation and the ameliorative effect of alpha-lipoic acid (ALA) on erythrocyte fragility. Thirty-six male Wistar rats divided into six groups of six rats each were used for the study. Groups I (S/oil) and II (ALA) were given soya oil (2 ml/kg) and ALA (60 mg/kg), respectively. Rats in group III (DLT) and IV (CPF) were exposed to DLT (6.25 mg/kg) and CPF (4.75 mg/kg) (1/20th of the previously determined LD50 of 125 mg/kg and 95 mg/kg, respectively, over a period of 48 h). Rats in group V (CPF + DLT) were co-exposed to CPF (4.75 mg/kg) and DLT (6.25 mg/kg), while those in group VI (ALA + CPF + DLT) were pretreated with ALA (60 mg/kg) and then co-exposed to CPF and DLT, 45 min later. The treatments were administered by gavage once daily for a period of 16 weeks. Blood collected at the end of the experimental period were analyzed for erythrocyte osmotic fragility and malondialdehyde (MDA) concentration. The study showed that chronic co-exposure to CPF and DLT resulted in an increase in erythrocyte fragility and MDA concentration which were ameliorated by supplementation with alpha-lipoic acid. The study concluded that repeated co-exposure to CPF and DLT elevated erythrocyte fragility probably due to increased lipid peroxidation, and pretreatment with alpha-lipoic acid ameliorated these alterations.

Abstract
Mitochondrial manganese superoxide dismutase (mMnSOD) plays a vital role in the defense against reactive oxygen species (ROS) in eukaryotic mitochondria. In this study, we isolated and identified a mMnSOD gene from Apis cerana cerana, which we named AccSOD2. Several putative transcription factor-binding sites were identified within the 5'-flanking region of AccSOD2, which suggests that AccSOD2 may be involved in organismal development and/or environmental stress responses. Quantitative real-time PCR analysis showed that AccSOD2 is highly expressed in larva and pupae during different developmental stages. In addition, the expression of AccSOD2 could be induced by cold (4 °C), heat (42 °C), H2O2, ultraviolet light (UV), HgCl2, and pesticide treatment. Using a disc diffusion assay, we provide evidence that recombinant AccSOD2 protein can play a functional role in protecting cells from oxidative stress. Finally, the in vivo activities of AccSOD2 were measured under a variety of stressful conditions. Taken together, our results indicate that AccSOD2 plays an important role in cellular stress responses and anti-oxidative processes and that it may be of critical importance to honeybee survival.

Abstract
Thioredoxins (Trxs) are a family of small, highly conserved and ubiquitous proteins that are involved in protecting organisms against toxic reactive oxygen species (ROS). In this study, a typical thioredoxin 2 gene was isolated from Apis cerana cerana, AccTrx2. The full-length cDNA sequence of AccTrx2 was composed of 407 bp containing a 318 bp open reading frame (ORF) that encodes a predicted protein of 105 amino acids, 11.974 kDa and an isoelectric point of 4.45. Expression profile of AccTrx2 as determined by a quantitative real-time PCR (qRT-PCR) analysis was higher in brain than in other tissues, with its highest transcript occurring on the 15day post-emergence adult and upregulated by such abiotic stresses as 4 °C, 16 °C, 25 °C, H2O2, cyhalothrin, acaricide, paraquat, phoxime and mercury (HgCl2) treatments. However, AccTrx2 was slightly repressed when exposed to 42 °C treatment. Characterisation of the recombinant protein showed that the purified AccTrx2 had insulin disulfide reductase activity and could protect DNA from ROS damage. These results indicate that AccTrx2 functions as an antioxidant that plays an important role in response to oxidative stress.

Abstract
Thioredoxin peroxidase (Tpxs) plays an important role in maintaining redox homeostasis and in protecting organisms from the accumulation of toxic reactive oxygen species (ROS). Here, we isolated a mitochondrial thioredoxin peroxidase gene from Apis cerana cerana, AccTpx-3. The open reading frame (ORF) of AccTpx-3 is 729 bp in length and encodes a predicted protein of 242 amino acids, 27.084 kDa and an isoelectric point of 8.70. Furthermore, the 980 bp 5' flanking region was cloned, and the transcription factor binding sites were predicted. A quantitative RT-PCR (Q-PCR) analysis indicated that AccTpx-3 was expressed higher in muscle than other tissues, with its highest expression occurring on the fourth day of the larval stage, followed by the fifteenth day of the adult stage. Moreover, the expression of the AccTpx-3 transcript was upregulated by such abiotic stresses as 4°C, 42°C, H(2)O(2), cyhalothrin, acaricide and phoxime treatments. In contrast, AccTpx-3 transcription was downregulated by other abiotic stresses, including 16°C, 25°C, ultraviolet light and HgCl(2). Recombinant AccTpx-3 protein acted as a potent antioxidant that resisted paraquat-induced oxidative stress and protected DNA from oxidative damage. Taken together, these results suggest that the AccTpx-3 protein is an antioxidant enzyme that may protect organisms from oxidative stress.

JOURNAL OF INSECT PHYSIOLOGY 2012; 58:782-791.

Abstract
Glutathione-S-transferases (GSTs) play an important role in protecting organisms against the toxicity of reactive oxygen species (ROS). However, no information is available for GSTs in the Chinese honey bee (Apis cerana cerana). In this study, we isolated and characterized a zeta class GST gene (AccGSTZ1) from the Chinese honey bee. This gene is present in a single copy and harbors five exons. The deduced amino acid sequence of AccGSTZ1 shared high sequence identity with homologous proteins and contained the highly conserved features of this gene family. The temporal and spatial expression profiles of AccGSTZ1 showed that AccGSTZ1 was highly expressed in fourth instar larvae during development, and the mRNA level of AccGSTZ1 was higher in the epidermis than that in other tissues. The expression pattern under oxidative stress revealed that AccGSTZ1 transcription was significantly upregulated by external factors, such as temperature challenges and H(2)O(2) treatment. The characterization of the purified protein revealed that AccGSTZ1 had low glutathione-conjugating activity, but the recombinant AccGSTZ1 protein displayed high antioxidant activity under oxidative stress. These data suggest that AccGSTZ1 is an oxidative stress-inducible antioxidant enzyme that plays an important role in the protection against oxidative stress and may be of critical importance for the survival of the honey bees.

Abstract
Thioredoxin peroxidases (Tpxs) play important roles in protecting organisms against the toxicity of reactive oxygen species (ROS) and regulating intracellular signal transduction. In the present study, we cloned the full cDNA of Tpx1 encoding a 195-amino acid protein from Apis cerana cerana (Acc). Based on the genomic DNA sequence, a 1442-bp 5'-flanking region was obtained, and the putative transcription factor binding sites were predicted. Quantitative PCR analysis showed that AccTpx1 was highly expressed in thorax and that the AccTpx1 transcript reached its highest level in two-week-old adult worker honeybees. Moreover, expression of the AccTpx1 transcript was increased by various abiotic stresses, such as ultraviolet light, HgCl(2) , and insecticide treatments. In addition, the recombinant AccTpx1 protein exhibited antioxidant activity; it removed hydrogen peroxide and protected DNA. These results suggest that AccTpx1 plays an important role in protecting honeybees from oxidative injury and may act in extending the lifespan of them.

Abstract
The purpose of this study was to investigate associations between pyrethroids occupational exposures, and risk of abnormal glucose regulation. Data from total of 3080 subjects in two pesticide factories were used. This was a population-based case-controlled study in China. In total, 18.3% of subjects with impaired glucose regulation (IGR) and 6.5% of subjects with diabetes, and the prevalence of abnormal glucose regulation was 24.8%, 86 subjects had known type 2 diabetes and 114 had newly diagnosed diabetes. The prevalence of subjects with abnormal glucose regulation increased from 21.3% in the controls to 29.3% in the exposures (χ² = 33.182, P < 0.001). Multivariate logistic regression was used to control potential confounders and calculate odd ratios as the estimate of effect. An indication of increased risk for abnormal glucose regulation was noted for exposure to pyrethroids (OR = 1.482, 95%CI = 1.238-1.774). Abnormal glucose regulation is common in subjects exposed to pyrethroids. The present investigation indicates the adverse health effects of pyrethroids are underestimated.

Abstract
Phospholipid hydroperoxide glutathione peroxidase (PHGPX) plays a crucial role in maintaining the integrity of membrane by reducing hydroperoxides of phospholipids. Here, we report the identification and characterization of two genes, designated AccGtpx-1 and AccGtpx-2, encoding PHGPX proteins from the Chinese honeybees, Apis cerana cerana. Alignment analysis showed that AccGtpx-1 and AccGtpx-2 shared high similarity with other known PHGPXs, which show similar structure to thioredoxin. These single copy genes showed complex exon-intron structures. The mRNA of AccGtpx-1 was detected in larvae, pupae and adults and that AccGtpx-2 was only found in adult worker bees. Furthermore, the expression of AccGtpx-1 could be induced by H(2)O(2), ultraviolet (UV) light, heat shock (37 degrees C), HgCl(2), imidacloprid, cyhalothrin, pyriproxyfen and methomyl. In contrast, AccGtpx-2 expression could only be induced by UV. These results indicated for the first time that the AccGtpx-1 and AccGtpx-2 genes encoding A. cerana cerana PHGPXs are regulated differently in response to environmental stressors.

Abstract
Continuous exposure of humans to pyrethroid-based mosquito repellents for longer durations may lead to adverse health effects. No information is available on long-term use of these mosquito repellents pertaining to the biochemical changes in human subjects. Therefore, the present study is an attempt to evaluate the status of health in human volunteers exposed to two commercially available mosquito repellent pyrethroids, allethrin and prallethrin, in terms of changes in plasma biochemical profile. Results of this study showed less but significant increase in the levels of plasma glucose, phospholipids, nitrite and nitrate, lipidperoxides with a decrease in plasma cholesterol. No significant changes were observed in the contents of total protein, albumin, globulin, HDL-C and LDL-C. However, SGPT activity increased significantly in persons exposed to only allethrin. Though the present investigation involving a limited number of human subjects indicates the onset of both protective changes as well as derangement in metabolism, a detailed and rigorous study is greatly warranted to arrive at a definite conclusion about the effects of pyrethroid mosquito repellents.
