1Grape Seed Proanthocyanidin Extract Alleviates Arsenic-induced Oxidative Reproductive Toxicity in Male Mice显示文摘Objective To determine the ability of grape seed proanthocyanidin extract(GSPE) in alleviating arsenic-induced reproductive toxicity. Methods Sixty male Kunming mice received the following treatments by gavage: normal saline solution(control); arsenic trioxide(ATO; 4 mg/kg); GSPE(400 mg/kg); ATO+GSPE(100 mg/kg); ATO+GSPE(200 mg/kg) and ATO+GSPE(400 mg/kg). Thereafter, the mice were sacrificed and weighed, and the testis was examined for pathological changes. Nuclear factor(erythroid-derived 2)-like 2(Nrf2), heme oxygenase 1(HO1), glutathione S-transferase(GST), NAD(P)H dehydrogenase, and quinone 1(NQO1) expression in the testis was detected by real-time PCR. Superoxide dismutase(SOD), glutathione(GSH), total antioxidative capability(T-AOC), malondialdehyde(MDA), 8-hydroxydeoxyguanosine(8-OHd G), and reproductive indexes were analyzed. Results ATO-treated mice showed a significantly decreased sperm count and testis somatic index and activity levels of SOD, GSH, and T-AOC than control group. Compared to the ATO-treated group, ATO +GSPE group showed recovery of the measured parameters. Mice treated with ATO+high-dose GSPE showed the highest level of m RNA expression of Nrf2, HO, NQO1, and GST. Conclusion GSPE alleviates oxidative stress damage in mouse testis by activating Nrf2 signaling, thus counteracting arsenic-induced reproductive toxicity.LI Shu Gang DING Yu Song NIU Qiang XU Shang Zhi PANG Li Juan MA Ru Lin JING Ming Xia FENG Gang Ling LIU Jia Ming GUO Shu Xia 2015Biomedical and Environmental Sciences2015,28,4:14
2The Predictive Value of Baseline HBs Ag Level and Early Response for HBs Ag Loss in Patients with HBe Ag-positive Chronic Hepatitis B during Pegylated Interferon Alpha-2a Treatment显示文摘Objective To explore the predictive value of baseline HBsAg level and early response for HBsAg loss in patients with HBeAg-positive chronic hepatitis B during pegylated interferon alpha-2a treatment. Methods A total of 121 patients with HBeAg-positive chronic hepatitis B who achieved HBsAg loss were enrolled; all patients were treated with PEG-IFNα-2a 180 μg/week. Serum HBV DNA and serological indicators(HBsAg, anti-HBs, HBeAg, and anti-HBe) were determined before and every 3 months during treatment. Results The median treatment time for HBsAg loss was 84 weeks(7-273 weeks), and 74.38%(90 cases) of the patients needed extended treatment(> 48 weeks). The correlation between baseline HBsAg levels and the treatment time of HBsAg loss was significant(B = 14.465, t = 2.342, P = 0.021). Baseline HBsAg levels together with the decline range of HBsAg at 24 weeks significantly correlated with the treatment time of HBsAg loss(B = 29.862, t = 4.890, P = 0.000 and B = 27.993, t = 27.993, P = 0.005). Conclusion Baseline HBsAg levels and extended therapy are critical steps toward HBsAg loss. Baseline HBsAg levels together with early response determined the treatment time of HBsAg loss in patients with HBeAg-positive chronic hepatitis B during pegylated interferon alpha-2a treatment.LI Ming Hui ZHANG Lu QU Xiao Jing LU Yao SHEN Ge LI Zhen Zhen WU Shu Ling LIU Ru Yu CHANG Min HU Lei Ping HUA Wen Hao SONG Shu Jing WAN Gang XIE Yao 2017Biomedical and Environmental Sciences2017,30,3:14
3Protective effects of a novel drug RC28-E blocking both VEGF and FGF2 on early diabetic rat retina显示文摘AIM: To investigate protective effects of a novel recombinant decoy receptor drug RC28-E on retinal damage in early diabetic rats.METHODS: The streptozotocin(STZ)-induced diabetic rats were randomly divided into 6 groups: diabetes mellitus(DM) group(saline, 3 μL/eye); RC28-E at low(0.33 μg/μL, 3 μL), medium(1 μg/μL, 3 μL), and high(3 μg/μL,3 μL) dose groups; vascular endothelial growth factor(VEGF) Trap group(1 μg/μL, 3 μL); fibroblast growth factor(FGF) Trap group(1 μg/μL, 3 μL). Normal control group was included. At week 1 and 4 following diabetic induction,the rats were intravitreally injected with the corresponding solutions. At week 6 following the induction, apoptosis in retinal vessels was detected by TUNEL staining.Glial fibrillary acidic protein(GFAP) expression was examined by immunofluorescence. Blood-retinal barrier(BRB) breakdown was assessed by Evans blue assay.Ultrastructural changes in choroidal and retinal vessels were analyzed by transmission electron microscopy(TEM).Content of VEGF and FGF proteins in retina was measured by enzyme linked immunosorbent assay(ELISA). The retinal expression of intercellular cell adhesion molecule-1(ICAM-1), tumor necrosis factor-α(TNF-α), VEGF and FGF genes was examined by quantitative polymerase chain reaction(qPCR).RESULTS: TUNEL staining showed that the aberrantly increased apoptotic cells death in diabetic retinal vascular network was significantly reduced by treatments of medium and high dose RC28-E, VEGF Trap, and FGF Trap(all P<0.05), the effects of medium and high dose RC28-E or FGF Trap were greater than VEGF Trap(P<0.01). GFAP staining suggested that reactive gliosis was substantially inhibited in all RC28-E and VEGF Trap groups, but the inhibition in FGF Trap group was not as prominent.Evans blue assay demonstrated that only high dose RC28-E could significantly reduce vascular leakage in early diabetic retina(P<0.01). TEM revealed that the ultrastructures in choroidal and retinal vessels were damaged in early diabetic retina, which was ameliorated to differential extents by each drug. The expression of VEGF and FGF2 proteins was significantly upregulated in early diabetic retina, and normalized by RC28-E at all dosages and by the corresponding Traps. The upregulation of ICAM-1 and TNF-α in diabetic retina was substantially suppressed by RC28-E and positive control drugs.CONCLUSION: Dual blockade of VEGF and FGF2 by RC28-E generates remarkable protective effects, including anti-apoptosis, anti-gliosis, anti-leakage, and improving ultrastructures and proinflammatory microenvironment,in early diabetic retina, thereby supporting further development of RC28-E into a novel and effective drug to diabetic retinopathy(DR).Qian-Hui Yang Yan Zhang Jing Jiang Mian-Mian Wu Qian Han Qi-Yu Bo Guang-Wei Yu Yu-Sha Ru Xun Liu Min Huang Ling Wang Xiao-Min Zhang Jian-Min Fang Xiao-Rong Li 2018International Journal of Ophthalmology(English edition)2018,11,6:9
4Regional path moving horizon tracking controller design for autonomous ground vehicles显示文摘A novel regional path tracking description is presented in this manuscript, and the moving horizon control method that is model predictive control(MPC) is proposed to discuss the regional path tracking issue which could avoid colliding road boundary when tracking a more complex road effectively. The feasible region for autonomous ground vehicles(AGVs) running is determined first according to the detected road boundaries.Then, in order to keep the actual trajectory of AGVs in the region and satisfy the safety requirements, MPC method is employed to design the path tracking controller considering actuator and road boundary constraints.In order to verify the effectiveness of the proposed method, experiments based on Hongqi AGV HQ430 are carried out, and the results illustrate that the presented method could be successfully applied to Hongqi AGV vehicle HQ 430.Hongyan GUO Feng LIU Ru YU Zhenping SUN Hong CHEN 2017Science China(Information Sciences)2017,60,1:9
5The Association of Socioeconomic Status with the Burden of Cataract-related Blindness and the Effect of Ultraviolet Radiation Exposure: An Ecological Study显示文摘Objective To assess the association of socioeconomic status with the burden of cataract blindness in terms of year lived with disability(YLD) rates and to determine whether ultraviolet radiation(UVR) levels modify the effect of socioeconomic status on this health burden.Methods National and subnational age-standardized YLD rates associated with cataract-related blindness were derived from the Global Burden of Disease(GBD) study 2017. The human development index(HDI) from the Human Development Report was used as a measure of socioeconomic status.Estimated ground-level UVR exposure was obtained from the Ozone Monitoring Instrument(OMI)dataset of the National Aeronautics and Space Administration(NASA).Results Across 185 countries, socioeconomic status was inversely associated with the burden of cataract blindness. Countries with a very high HDI had an 84% lower age-standardized YLD rate [95%confidence interval(CI): 60%–93%, P < 0.001] than countries with a low HDI;for high-HDI countries, the proportion was 76%(95% CI: 53%–88%, P < 0.001), and for medium-HDI countries, the proportion was48%(95% CI: 15%–68%, P = 0.010;P for trend < 0.001). The interaction analysis showed that UVR exposure played an interactive role in the association between socioeconomic status and cataract blindness burden(P value for interaction = 0.047).Conclusion Long-term high-UVR exposure amplifies the association of poor socioeconomic status with the burden of cataract-related blindness. The findings emphasize the need for strengthening UVR exposure protection interventions in developing countries with high-UVR exposure.DENG Yan YANG Dan YU Jia Ming XU Jing Xian HUA Hui CHEN Ren Tong WANG Nan OU Feng Rong LIU Ru Xi WU Bo LIU Yang 2021Biomedical and Environmental Sciences2021,34,2:6
6Association between Metabolic Syndrome and Carotid Atherosclerosis: A Cross-sectional Study in Northern China显示文摘Objective Increased carotid artery intima-media thickness(CIMT)and carotid plaque as manifestations of carotid atherosclerosis have been used as markers of cardiovascular disease(CVD).The components of metabolic syndrome(Met S)are linked to CVD,but the association between Met S and CVD is controversial.Methods A total of 8,933 Chinese adults aged 40 years or older from 2010 to 2014 were selected from the Jidong and Kailuan communities.Met S was defined by the International Diabetes Federation criteria.CIMT and carotid plaque were measured using color Doppler ultrasound.Logistic regression models were used to assess the association of Met S with carotid plaque and CIMT.Results Met S was found among 3,461(3,461/8,933)participants.The odds ratio and 95%confidence internal(CI)for carotid plaques in participants with Met S was 1.16(1.03-1.30).The risk of carotid plaques increased with the number of Met S components.The average CIMT was higher in participants with Met S(β=0.020,95%CI,0.014-0.027)and in participants with more Met S components.Conclusion Individuals with Met S are at an increased risk for carotid atherosclerosis compared to those without MetS.ZHOU Ping An ZHANG Chen Huan CHEN Yan Ru LI Dong SONG Dai Yu LIU Hua Min ZHOU Ming Yue SONG Guo Shun CHEN Sheng Yun 2019Biomedical and Environmental Sciences2019,32,12:6
7Generation of electricity from CO_2 mineralization: Principle and realization显示文摘Current CO2 reduction and utilization technologies suffer from high energy consuming. Thus, an energy favourable route is in urgent demanding. CO2 mineralization is theoretically an energy releasing process for CO2 reduction and utilization, but an approach to recovery this energy has so far remained elusive. For the first time, here we proposed the principle of harvesting electrical energy directly from CO2 mineralization, and realized an energy output strategy for CO2 utilization and reduction via a CO2-mineralization fuel cell(CMFC) system. In this system CO2 and industrial alkaline wastes were used as feedstock, and industrial valuable Na HCO3 was produced concomitantly during the electricity generation. The highest power density of this system reached 5.5 W/m2, higher than many microbial fuel cells. The maximum open circuit voltage reached 0.452 V. Moreover, this system was demonstrated viable to low concentration CO2(10%) and other carbonation process. Thus, the existing of an energy-generating and environmentally friendly strategy to utilize CO2 as a supplement to the current scenario of CO2 emission control has been demonstrated.XIE He Ping WANG Yu Fei HE Yang GOU Ma Ling LIU Tao WANG Jin Long TANG Liang JIANG Wen ZHANG Ru XIE Ling Zhi LIANG Bin 2014Science China(Technological Sciences)2014,57,12:6

10Integrated lithium niobate single-mode lasers by the Vernier effect显示文摘Microcavity lasers based on erbium-doped lithium niobate on insulator(LNOI),which are key devices for LNOI integrated photonics,have attracted significant attention recently.In this study,we report the realization of a C-band single-mode laser using the Vernier effect in two coupled erbium-doped LNOI microrings with different radii under the pump of a 980-nm continuous laser.The laser,operating stably over a large range of pumping power,has a pump threshold of about 200μW and a side-mode suppression ratio exceeding 26 dB.The high-performance LNOI single-mode laser will promote the development of lithium niobate integrated photonics.Ru Zhang Chen Yang ZhenZhong Hao Di Jia Qiang Luo DaHuai Zheng HongDe Liu XuanYi Yu Feng Gao Fang Bo YongFa Kong GuoQuan Zhang JingJun Xu 2021Science China(Physics,Mechanics & Astronomy)2021,64,9:4
11Simultaneous determination of metronidazole and tinidazole in plasma by using HPLC-DAD coupled with second-order calibration显示文摘A method using HPLC-DAD coupled with second-order calibration was developed to simultaneously determine metronidazole and tinidazole in plasma samples in this paper.The second-order calibration method based on APTLD(alternating penalty trilinear decomposition) algorithm was proposed to analyze the three-way HPLC-DAD data from both standard and prediction samples, which makes it possible that calibration can be performed even in the presence of unknown interferences with a simple and green chromatographic condition and short analysis time.The results showed that good recoveries were obtained although the chromatographic and spectral profiles of the analytes of interest as well as background were partially overlapped with each other in plasma samples.Li Qun Ouyang Hai Long Wu Ya Juan Liu Jian Yue Wang Yong Jie Yu Hong Yan Zou Ru Qin Yu 2010Chinese Chemical Letters2010,21,10:4
12Development of Human in vitro Brain-blood Barrier Model from Induced Pluripotent Stem Cell-derived Endothelial Cells to Predict the in vivo Permeability of Drugs显示文摘An in vitro blood-brain barrier(BBB) model is critical for enabling rapid screening of the BBB permeability of the drugs targeting on the central nervous system.Though many models have been developed, their reproducibility and renewability remain a challenge. Furthermore, drug transport data from many of the models do not correlate well with the data for in vivo BBB drug transport.Induced-pluripotent stem cell(i PSC) technology provides reproducible cell resources for in vitro BBB modeling.Here, we generated a human in vitro BBB model by differentiating the human i PSC(hi PSC) line GM25256 into brain endothelial-type cells. The model displayed BBB characteristics including tight junction proteins(ZO-1,claudin-5, and occludin) and endothelial markers(von Willebrand factor and Ulex), as well as high transendothelial electrical resistance(TEER)(1560 X.cm2±230 X.cm2) and c-GTPase activity. Co-culture with primary rat astrocytes significantly increased the TEER of the model(2970 X.cm2 to 4185 X.cm2). RNAseq analysis confirmed the expression of key BBB-related genes in the hi PSC-derived endothelial cells in comparison with primary human brain microvascular endothelial cells,including P-glycoprotein(Pgp) and breast cancer resistant protein(BCRP). Drug transport assays for nine CNS compounds showed that the permeability of non-Pgp/BCRP and Pgp/BCRP substrates across the model was strongly correlated with rodent in situ brain perfusion data for these compounds(R2= 0.982 and R2= 0.9973,respectively), demonstrating the functionality of the drug transporters in the model. Thus, this model may be used to rapidly screen CNS compounds, to predict the in vivo BBB permeability of these compounds and to study the biology of the BBB.Yuan Li Xueying Sun Houfu Liu Liang Huang Guofeng Meng Yu Ding Wenji Su Jiaqi Lu Sophie Gong Georg C.Terstappen Ru Zhang Wandong Zhang 2019Neuroscience Bulletin2019,35,6:3
13Optimal Waist Circumference Cut-off values for Identifying Metabolic Risk Factors in Middle-aged and Elderly Subjects in Shandong Province of China显示文摘Objective To study the optimal waist circumference(WC) cut-off values for identifying metabolic risk factors in middle-aged and elderly subjects in Shandong Province of China. Methods A total of 2 873 men and 5 559 women were included in this cross-sectional study. Metabolic syndrome(MetS) was diagnosed according to the definition of Chinese Diabetes Society in 2004. The relation between WC and MetS was analyzed by multivariate logistic regression analysis. The optimal WC cut-off values were identified using the area under the ROC curve and the different diagnostic criteria for central obesity were compared. Results The WC was the risk factor for MetS independent of BMI, blood glucose, blood lipid, and blood pressure. The optimal WC cut-off value was 83.8 cm and 91.1 cm for identifying MetS in women and men, respectively. Compared with 80 cm and 85 cm for women and men, 85 cm and 90 cm had a higher Youden index for identifying all metabolic risk factors and MetS in women and men. Conclusion The appropriate WC cut-off value is 85 cm and 90 cm for identifying central obesity and MetS in women and men in Shandong Province of China.HOU Xin Guo WANG Chuan MA Ze Qiang YANG Wei Fang WANG Ji Xiang LI Cheng Qiao WANG Yu Lian LIU Shu Min Hu Xiu Ping ZHANG Xiu Ping JIANG Mei WANG Wei Qing NING Guang ZHENG Hui Zhen MA Ai Xia SUN Yu SONG Jun LIN Peng LIANG Kai LIU Fu Qiang LI Wen Juan XIAO Juan GONG Lei WANG Mei Jian LIU Ji Dong YAN Fei YANG Jun Peng WANG Ling Shu TIAN Meng ZHAO Ru Xing JIANG Ling CHEN Li 2014Biomedical and Environmental Sciences2014,27,5:3
14Identification of Heterodera schachtii on sugar beet in Xinjiang Uygur Autonomous Region of China显示文摘The sugar beet cyst nematode,Heterodera schachtii,is a major parasite of sugar beet which has been recognized and listed as a quarantine nematode in China and more than 20 countries and regions worldwide.A survey for important nematodes was undertaken in the sugar beet planting area of China during 2015-2018,and numerous cysts were collected from sugar beet fields in Xinyuan County,Xinjiang Uygur Autonomous Region of China.The observations of morphological and morphometric characteristics revealed that cysts,vulval cones and second-stage juveniles of the Xinjiang population were in the same range of each other and within those of other reported H.schachtii populations.Molecular analysis of rDNA-ITS,28S-D2/D3 and mtDNA cytochrome c oxidase subunit 1(COI)gene sequences suggested that the Xinjiang population clustered in a branch with those foreign populations,and the sequence similarity was as high as 99.81-100%.Moreover,this result was confirmed by PCR assay with species-specific primer SHF6 and rDNA2 of H.schachtii,and the pathogenicity test confirmed successful Xinjiang population reproduction in both plant hosts.In conclusion,based on morphological and molecular characterization,this study confirmed that the cyst nematode population collected from sugar beet fields in Xinjiang is H.schachtii.As far as we know,this is the first report of H.schachtii on sugar beets in Xinjiang,China.PENG Huan LIU Hui GAO Li JIANG Ru LI Guang-kuo GAO Hai-feng WU Wei WANG Jun ZHANG Yu HUANG Wen-kun KONG Ling-an PENG De-liang 2022Journal of Integrative Agriculture2022,21,6:2

17Hymecromone:a clinical prescription hyaluronan inhibitor for efficiently blocking COVID-19 progression显示文摘Currently,there is no effective drugs for treating clinically COVID-19 except dexamethasone.We previously revealed that human identical sequences of SARS-CoV-2 promote the COVID-19 progression by upregulating hyaluronic acid(HA).As the inhibitor of HA synthesis,hymecromone is an approved prescription drug used for treating biliary spasm.Here,we aimed to investigate the relation between HA and COVID-19,and evaluate the therapeutic effects of hymecromone on COVID-19.Firstly,HA was closely relevant to clinical parameters,including lymphocytes(n=158;r=−0.50;P<0.0001),C-reactive protein(n=156;r=0.55;P<0.0001),D-dimer(n=154;r=0.38;P<0.0001),and fibrinogen(n=152;r=0.37;P<0.0001),as well as the mass(n=78;r=0.43;P<0.0001)and volume(n=78;r=0.41;P=0.0002)of ground-glass opacity,the mass(n=78;r=0.48;P<0.0001)and volume(n=78;r=0.47;P<0.0001)of consolidation in patient with low level of hyaluronan(HA<48.43 ng/mL).Furthermore,hyaluronan could directly cause mouse pulmonary lesions.Besides,hymecromone remarkably reduced HA via downregulating HAS2/HAS3 expression.Moreover,89%patients with hymecromone treatment had pulmonary lesion absorption while only 42%patients in control group had pulmonary lesion absorption(P<0.0001).In addition,lymphocytes recovered more quickly in hymecromone-treated patients(n=8)than control group(n=5)(P<0.05).These findings suggest that hymecromone is a promising drug for COVID-19 and deserves our further efforts to determine its effect in a larger cohort.Shuai Yang Yun Ling Fang Zhao Wei Li Zhigang Song Lu Wang Qiuting Li Mengxing Liu Ying Tong Lu Chen Daoping Ru Tongsheng Zhang Kaicheng Zhou Baolong Zhang Peng Xu Zhicong Yang Wenxuan Li Yuanlin Song Jianqing Xu Tongyu Zhu Fei Shan Wenqiang Yu Hongzhou Lu 2022Signal Transduction and Targeted Therapy2022,7,4:2
18Inverted U-Shaped Associations between Glycemic Indices and Serum Uric Acid Levels in the General Chinese Population:Findings from the China Cardiometabolic Disease and Cancer Cohort(4C)Study显示文摘Objective The relationship between serum uric acid(SUA)levels and glycemic indices,including plasma glucose(FPG),2-hour postload glucose(2 h-PG),and glycated hemoglobin(HbA1 c),remains inconclusive.We aimed to explore the associations between glycemic indices and SUA levels in the general Chinese population.Methods The current study was a cross-sectional analysis using the first follow-up survey data from The China Cardiometabolic Disease and Cancer Cohort Study.A total of 105,922 community-dwelling adults aged≥40 years underwent the oral glucose tolerance test and uric acid assessment.The nonlinear relationships between glycemic indices and SUA levels were explored using generalized additive models.Results A total of 30,941 men and 62,361 women were eligible for the current analysis.Generalized additive models verified the inverted U-shaped association between glycemic indices and SUA levels,but with different inflection points in men and women.The thresholds for FPG,2 h-PG,and HbA1 c for men and women were 6.5/8.0 mmol/L,11.0/14.0 mmol/L,and 6.1/6.5,respectively(SUA levels increased with increasing glycemic indices before the inflection points and then eventually decreased with further increases in the glycemic indices).Conclusion An inverted U-shaped association was observed between major glycemic indices and uric acid levels in both sexes,while the inflection points were reached earlier in men than in women.ZHU Yuan Yue ZHENG Rui Zhi WANG Gui Xia CHEN Li SHI Li Xin SU Qing XU Min XU Yu CHEN Yu Hong YU Xue Feng YAN Li WANG Tian Ge ZHAO Zhi Yun QIN Gui Jun WAN Qin CHEN Gang GAO Zheng Nan SHEN Fei Xia LUO Zuo Jie QIN Ying Fen HUO Ya Nan LI Qiang YE Zhen ZHANG Yin Fei LIU Chao WANG You Min WU Sheng Li YANG Tao DENG Hua Cong ZHAO Jia Jun CHEN Lu Lu MU Yi Ming TANG Xu Lei HU Ru Ying WANG Wei Qing NING Guang LI Mian LU Jie Li BI Yu Fang 2021Biomedical and Environmental Sciences2021,34,1:2

20Knockout of glutathione peroxidase 5 down-regulates the piRNAs in the caput epididymidis of aged mice显示文摘The mammalian epididymis not only plays a fun dame ntal role in the maturati on of spermatozoa,but also provides protecti on agai nst various stressors.The foremost among these is the threat posed by oxidative stress,which arises from an imbalance in reactive oxygen species and can elicit damage to cellular lipids,proteins,and nucleic acids.In mice,the risk of oxidative damage to spermatozoa is mitigated through the expression and secretion of glutathione peroxidase 5(GPX5)as a major luminal scavenger in the proximal caput epididymidal segment.Accordingly,the loss of GPX5^-/-mediated protection leads to impaired DNA integrity in the spermatozoa of aged Gpx57 mice.To explore the underlying mechanism,we have conducted transcriptomic analysis of caput epididymidal epithelial cells from aged(13 months old)Gpx5^-/-m mice.This analysis revealed the dysregulation of several thousand epididymal mRNA transcripts,in eluding the downregulation of a subgroup of piRNA pathway gen es,in aged Gpx5^-/-mice.In agreeme nt with these fin dings,we also observed the loss of piRNAs,which potentially bind to the P-element-induced wimpy testis(PlWI)-like proteins PIWIL1 and PIWIL2.The absence of these piRNAs was correlated with the elevated mRNA levels of their putative gene targets in the caput epididymidis of Gpx5^-/-mice.Importantly,the oxidative stress response genes tend to have more targeting piRNAs,and many of them were among the top increased genes upon the loss of GPX5^-/-.Taken together,our findings suggest the existence of a previously uncharacterized somatic piRNA pathway in the mammalian epididymis and its possible invoIvement in the aging and oxidative stress-mediated responses.Chen Chu Lu Yu Joelle Henry-Berger Yan-Fei Ru Ayhan Kocer Alexandre Champroux Zhi-Tong Li Miao He Sheng-Song Xie Wu-Bin Ma Min-Jie Ni Zi-Mei Ni Yun-Li Guo Zhao-Liang Fei Lan-Tao Gou Qiang Liu Samanta Sharma Yu Zhou Mo-Fang Liu Charlie Degui Chen Andrew L Eamens Brett Nixon Yu-Chuan Zhou Joel R Drevet Yong-Lian Zhang 2020Asian Journal of Andrology2020,22,6:2
