Objective To investigate the role of NADPH oxidase in Herpes simplex virus 1 (HSV-1)-induced matrix metalloproteinase 9(MMP-9)expression in murine microglial BV2 cells.Methods BV2 cells induced by HSV-1 were divided into normal control group,HSV-1 infection group,and two apocynin treatment groups(in which apocynin was administered at 0.5 and 1.0 mmol/L after HSV-1 infection).MMP-9 gelatinolytic activity in the supematants of the cell cultures Was assessed by zymography.Semi-quantitative reverse transcription polymerase chain reaction(RT-PCR)was used to detect the mRNA expressions of NADPH oxidase subunit p47phox and matrix metalloproteinase-9 (MMP-9),and the intracellular reactive oxygen species(ROS)levels were measured by dihydroethidium staining(DHE).Results Compared to the normal control group,HSV-1 infection of the cells resulted in significantly up-regulated mRNA expression of NADPH oxidase subunit p47phox and MMP-9,and also in a 2-fold increase in the intracellular ROS level(P<0.05).These changes were attenuated by the application of apocynin,but the mRNA expressions of p47phox and MMP-9 and ROS level still remained significantly higher than those in the normal control group(P<0.05).Conclusion HSV-1 may induce MMP-9 activation through the generation of NADPH oxidase-dependent ROS in murine microglia.

OBJECTIVETo investigate the effects of ammonium perchlorate (AP) on thyroid functions and mRNA expression levels of thyroglobulin (Tg) and thyroperoxidase (TPO) genes of rats.
METHODSThirty SD male rats were randomly divided into six groups: control group, iodine-deficient group, low dose AP group (130 mg/kg), moderate dose AP group (260 mg/kg), high dose AP group (520 mg/kg) and high iodine-combined group. After the rats were exposed orally for 90 days, serum free-thyroxine (FT(4)), free-triiodothyronine (FT(3)) and thyroid stimulating hormone (TSH) were measured using radioimmunoassays. mRNA expression levels of thyroglobulin (Tg) and thyroperoxidase (TPO) genes were detected by real-time quantitative PCR.
RESULTSSerum FT(4) levels in moderate dose AP group and high dose AP group were [(9.540 ± 1.327) fmol/ml] and [(6.509 ± 1.949) fmol/ml] respectively, which were significantly lower than that [(13.505 ± 1.276) fmol /ml] in control group (P < 0.05 or P < 0.01). Serum TSH level in high dose AP group was [(1.227 ± 0.295) mIU/L], which was significantly higher than that [(0.545 ± 0.282) mIU/L] in control group (P < 0.05). The mRNA expression levels of thyroglobulin (Tg) gene in all groups exposed to AP were significantly lower than that in control group (P < 0.01). The mRNA expression level of thyroperoxidase (TPO) gene in high dose AP group was significantly higher than that in control group (P < 0.05).
CONCLUSIONAP can reduce the serum FT(3) and FT(4) levels of rats, increase the serum TSH level of rats and decrease obviously the mRNA expression levels of Tg and TPO genes. In addition, high iodine can reduce the toxic effects of AP on thyroid gland of rats to some extent.

The aim of this study is to investigate the anti-inflammatory effect of the adenosine derivative N6-(3-hydroxylaniline) adenosine (WS070117M1) on cigarette smoke plus LPS (lipopolysaccharide)-induced chronic obstructive pulmonary disease (COPD) in mice and its mechanism. COPD model was established by exposing male BALB/c mice to cigarette smoke and challenged with LPS inhalation. Supernatants of bronchoalveolar lavage fluid (BALF) were harvested and IL-1β, IL-6, IL-8 and TGF-β1 levels were measured by ELISA (enzyme-linked immunesorbent assay). The number of total white blood cells and neutrophils in bronchoalveolar lavage fluid was counted separately. Lung tissue was stained with Mayer 's hematoxylin and eosin for histopathologic examination. pAMPKa protein expression and distribution of lung tissue were analyzed by immunohistochemistry method. In vitro, levels of AMPKα phosphorylation in phorbol-12- myristate-13-acetate (PMA) differentiated THP-1 cells was detected by immunohistochemistry, IL-8 level in supernatants of cigarette smoke condensate stimulating PMA differentiated THP-1 cells was measured by ELISA. The results showed that WS070117M1 treatment significantly activated AMPKa in the lung tissue. It also resulted in down regulation of IL-1β, IL-6, IL-8 and TGF-β1 levels in bronchoalveolar lavage fluid and IL-8 level in cigarette smoke condensate stimulating PMA differentiated THP-1 cells. In addition, WS070117M1 could inhibit the recruitment of total white blood cells and neutrophils. These results suggest that WS070117M1 may alleviate the airway inflammation by activating AMPK in the lung tissue.

An anti-alpha-synuclein (alpha-SYN) monoclonal antibody produced in our laboratory was used to investigate the effect of repeated acute hypoxic treatments on the expression of alpha-SYN in the mouse cerebral cortex. Western blot analysis showed that the expression levels of alpha-SYN in the cortex changed accordingly upon hypoxic exposure times, as that the alpha-synuclein level significantly increased after the first hypoxic exposure and then dropped down to the background level after the fourth hypoxic exposure. Immunohistochemical staining revealed that the alpha-SYN-immunopositive substance was localized not only in the nerve endings, but also within the nuclei of some neurons. The cell density of the neurons with alpha-SYN immunopositive nuclei was increased significantly after the first hypoxic exposure but returned back to control levels after the fourth hypoxic exposure. Our results indicate that both of the alpha-SYN expression level in the brain and the number of the neurons with alpha-SYN positive nuclei are affected by the repeated acute hypoxic treatments and that this modification is hypoxic time-dependent. The mechanism and the physiological significance underlying these changes need to be further investigated.

OBJECTIVETo detect the MSX1 gene mutation in a Chinese family with oligodontia.
METHODSBlood samples were obtained from seven affected and seven unaffected individuals in the pedigree. All exons and flanking intronic boundaries of the MSX1 gene were amplified with polymerase chain reaction technique and then directly sequenced. The website of bioinformatics was used to predict the effect of the mutation on the function.
RESULTSA splicing mutation (IVS1-2A > G) was found at position -2 near the 3' end of the IVS1 of MSX1, which made a change of the intron 1 splice acceptor site. None of the mutation was found in normal individuals of the family and in 100 unrelated healthy matched control individuals.
CONCLUSIONSIVS1-2A > G was a novel splicing mutation identified in the MSX-1 gene and it might be responsible for nonsyndromic oligodontia in this family.
