SGC-7901 cells. Eightday after treatment with various concentrations of c9, tl1-CLA mentioned above, the inhibition rates were 5.92 % ,20.15 % ,75.61% and 82.44 % ,respectively and inhibitory effeotof c9, tll-CLA on DNA synthesis (except for 25 tmol/L,24h) showed significantly less 3H-TdR incorporation than thatin the negative controls (P < 0. 05 and P < 0. 01).Immunocytochemical staining demonstrated that SGC-7901cells preincubated in media supplemented with different c9,tl1-CLA concentrations at various times significantlydecreased the expressions of PCNA (the expression rateswere7.2-3.0 %,24 h and 9.1-0.9 % at 48 h, respectively),Cyclin A (l1.0-2.3 %, 24 h and 8.5-0.5 % ,48 h), B1 (4.8-1.8% at 24 h and 5.5-0.6 % at 48 h)and D1 (3.6-1.4 % at 24 hand 3.7 %-0 at 48 h) as compared with those in the negativecontrols(the expressions of PCNA, Cyclin A, B1 and D1were 6.5 % at 24h and 9.0 % at 48 h, 4.2% at 24h and5.1% at 48 h, 9.5 % at 24h and 6.0 % at 48 h,respectively)(P< 0.01), whereas the expressions of p16ink4a and p21clp/waf1,cyclin-dependent kinases inhibltors(CDKI), were increased.CONCLUSION: The cell growth and proliferation of SGC-7901cell is inhibited by c9, tll-CLA via blocking the cell cycle,with reduced expressions of cyclin A, B1 and D1 andenhanced expressions of CDKI( p16ink4a and p21cip/waf1). | Jia-Ren Liu Bai-Xiang Li Bing-Qing Chen Ying-ben Xue Yan-Mei Yang Yu-Mei Zheng,Department of Toxicological Health,Public Health College,Harbin Medical University,Harbin 150001,Heilongjiang Province,China Xiao-Hui Han ICU of Cardiological Surgery,The Second Hospital,Harbin Medical University,Harbin 150001,Heilongjiang Province,China Rui-Hai Liu,Food Science and Toxicology,Department of Food Science,Cornell University,Ithaca,NY 14853-7201,USA | 2002 | World Journal of Gastroenterology2002,8,2: | 26 |
| 2 | Microglia regulation of synaptic plasticity and learning and memory显示文摘Microglia are the resident macrophages of the central nervous system.Microglia possess varied morphologies and functions.Under normal physiological conditions,microglia mainly exist in a resting state and constantly monitor their microenvironment and survey neuronal and synaptic activity.Through the C1 q,C3 and CR3'Eat Me'and CD47 and SIRPα'Don't Eat Me'complement pathways,as well as other pathways such as CX3 CR1 signaling,resting microglia regulate synaptic pruning,a process crucial for the promotion of synapse formation and the regulation of neuronal activity and synaptic plasticity.By mediating synaptic pruning,resting microglia play an important role in the regulation of experience-dependent plasticity in the barrel cortex and visual cortex after whisker removal or monocular deprivation,and also in the regulation of learning and memory,including the modulation of memory strength,forgetfulness,and memory quality.As a response to brain injury,infection or neuroinflammation,microglia become activated and increase in number.Activated microglia change to an amoeboid shape,migrate to sites of inflammation and secrete proteins such as cytokines,chemokines and reactive oxygen species.These molecules released by microglia can lead to synaptic plasticity and learning and memory deficits associated with aging,Alzheimer's disease,traumatic brain injury,HIV-associated neurocognitive disorder,and other neurological or mental disorders such as autism,depression and post-traumatic stress disorder.With a focus mainly on recently published literature,here we reviewed the studies investigating the role of resting microglia in synaptic plasticity and learning and memory,as well as how activated microglia modulate disease-related plasticity and learning and memory deficits.By summarizing the function of microglia in these processes,we aim to provide an overview of microglia regulation of synaptic plasticity and learning and memory,and to discuss the possibility of microglia manipulation as a therapeutic to ameliorate cognitive deficits associated with aging,Alzheimer's disease,traumatic brain injury,HIV-associated neurocognitive disorder,and mental disorders. | Jessica Cornell Shelbi Salinas Hou-Yuan Huang Miou Zhou | 2022 | Neural Regeneration Research2022,17,4: | 26 |

| 5 | Ceramide induces release of mitochondrial proapop-totic proteins in caspase-dependent and -independent manner in HT-29 cells显示文摘In this study, the release of mitochondrial proapoptotic intermembrane space proteins induced by ex-ogenous C2-ceramide in human colon carcinoma (HT-29) cell line was investigated. HT-29 cells were treated with 12.5, 25 and 50 μmol/L C2-ceramide in vitro. Flow cytometer was used to detect the mito-chondrial membrane potential (ΔΨm). Subcellular fractions were extracted by Mitochondrial/Cytosol Fractionation Kit after C2-ceramide treatment for 24 h. SDS-PAGE was used to determine the level of cytochrome c (Cyt c), high temperature requirement A2 (HtrA2) and second mitochondrial-derived ac-tivator of caspases (Smac) released from mitochondria, the expression of X-linked inhibitor of apop-tosis protein (XIAP) and caspase-3 for 24 h. The results showed that ΔΨm began to decrease from 6 h after 25 and 50 μmol/L C2-ceramide treatment (P<0.05) and cyclosporin A (CsA) could inhibit the col-lapse of ΔΨm through regulating mitochondrial membrane permeability transition pore. There was no effect of C2-ceramide on the expression of Cyt c, HtrA2 and Smac in the total levels. 12.5, 25 and 50 μmol/L C2-ceramide could induce Cyt c, HtrA2 and Smac to release from mitochondria to cytosol and down-regulate the expression of XIAP (P<0.05). Also there was expression of cleaved caspase-3 with C2-ceramide treatment. After the treatment with caspase inhibitor, C2-ceramide still induced the release of Cyt c and HtrA2, but Smac did not. Therefore, C2-ceramide could induce apoptosis of HT-29 cells through the mitochondria pathway. The release of Cyt c, HtrA2 and Smac from mitochondria did not occur via the same mechanism, the release of Cyt c and HtrA2 was caspase-independent and the re-lease of Smac was caspase-dependent. | ZHANG XiaoFeng1, LI BaiXiang1, ZHANG Yang1 & LIU JiaRen2 1 Public Health College, Harbin Medical University, Harbin 150081, China 2 Department of Food Science, Cornell University, New York 14853-7201, USA | 2008 | Science China(Life Sciences)2008,51,1: | 5 |
| 6 | Principles and Characteristics of Polymerization-Induced Self-Assembly with Various Polymerization Techniques显示文摘A chemical reaction that drives a physical polymer selfassembly process,namely,polymerization-induced self-assembly(PISA),combines block copolymer synthesis and nanoparticle formation efficiently at high polymer concentrations.Various nanoparticlemorphologies such as spheres,worms,and vesicles can be prepared readily in polar and nonpolarmedia.PISA has been well developed in combination with reversible addition-fragmentation chain transfer(RAFT)polymerization.Notably,developments with other polymerization methods are also achieved.In this report,first,we discuss the general principles of RAFT-PISA and the nanoparticles generated from this method.Specifically,new insights into polymer nucleation and subsequent morphological evolution are highlighted.Subsequently,PISA formulations that use other polymerization methods[atom transfer radical polymerization(ATRP),nitroxide-mediated polymerization(NMP),ring-opening metathesis polymerization(ROMP),and ring-opening polymerization(ROP)of N-carboxyanhydrides(NCAs)]are summarized in detail.Finally,more exotic PISA formulations are emphasized:these are based on organotelluriummediated living radical polymerization(TERP),living anionic polymerization(LAP),addition-fragmentation chain transfer(AFCT)polymerization,reversible complexation-mediated polymerization(RCMP),and cobalt-mediated radical polymerization(CMRP),or utilize a comonomer that undergoes radical ringopening polymerization(rROP).This reviewis concluded with a perspective on the status and potential of PISA. | Erik Jan Cornel Jinhui Jiang Shuai Chen Jianzhong Du | 2021 | CCS Chemistry2021,3,4: | 4 |

| 15 | Influence of Genista Tinctoria L or Methylparaben on Subchronic Toxicity of Bisphenol A in Rats显示文摘Objective To evaluate the influence of an extract of Genista tinctoria L. herba(GT) or methylparaben(MP) on histopathological changes and 2 biomarkers of oxidative stress in rats subchronicly exposed to bisphenol A(BPA). Methods Adult female Wistar rats were orally exposed for 90 d to BPA(50 mg/kg), BPA+GT(35 mg isoflavones/kg) or BPA+MP(250 mg/kg). Plasma and tissue samples were taken from liver, kidney, thyroid, uterus, ovary, and mammary gland after 30, 60, and 90 d of exposure respectively. Lipid peroxidation and in vivo hydroxyl radical production were evaluated by histological analysis along with malondialdehyde and 2,3-dihydroxybenzoic acid detection. Results The severity of histopathological changes in liver and kidneys was lower after GT treatment than after BPA or BPA+MP treatment. A minimal thyroid receptor antagonist effect was only observed after BPA+MP treatment. The abnormal folliculogenesis increased in a time-dependent manner, and the number of corpus luteum decreased. No significant histological alterations were found in the uterus. The mammary gland displayed specific estrogen stimulation changes at all periods. Both MP and GT revealed antioxidant properties reducing lipid peroxidation and BPA-induced hydroxyl radical generation. Conclusion GT L. extract ameliorates the toxic effects of BPA and is proved to have antioxidant potential and antitoxic effect. MP has antioxidant properties, but has either no effect or exacerbates the BPA-induced histopathological changes. | Daniela-Saveta POPA Pompei BOLFA Bela KISS Laurian VLASE Ramona PLTINEAN Anca POP Cornel CTOI Gianina CRISAN Felicia LOGHIN | 2014 | Biomedical and Environmental Sciences2014,27,2: | 2 |
