As a major microtubule-associated protein,tau plays an important role in promoting microtubule assembly and stabilizing microtubules.In Alzheimer's disease (AD) and other tauopathies,the abnormally hyperphosphorylated tau proteins are aggregated into paired helical filaments and accumulated in the neurons with the form of neurofibrillary tangles.An imbalanced regulation in protein kinases and protein phosphatases is the direct cause of tau hyperphosphorylation.Among various kinases and phosphatases,glycogen synthase kinase-3β (GSK-3β) and protein phosphatase 2A (PP2A) are the most implicated.Accumulation of the hyperphosphorylated tau induces synaptic toxicity and cognitive impairments.Here,we review the upstream factors or pathways that can regulate GSK-3β or PP2A activity mainly based on our recent findings.We will also discuss the mechanisms that may underlie tau-induced synaptic toxicity.

AIM: To investigate the potential role of 14-3-3 tau in trophoblast cells on invasiveness. METHODS: 14-3-3 tau expression was detected in first-trimester villi, deciduas and human trophoblastic cell line (BeWo) by immunohistochemistry. Small interference RNA (siRNA) targeting 14-3-3 tau was transfected into BeWo cells. The effects of down-regulated 14-3-3 tau on invasion of human trophoblasts cell line BeWo were examined by matrigel invasion assay, and the transcription, translation of E-cadherin and snail were estimated by RT-PCR or Western blotting. U0126 was used to detect the extracellular-signal related kinase 1/2 (ERK1/2) function on down-regulation of 14-3-3 tau induced cell invasion. RESULTS: 14-3-3 tau was detected in the invasive trophoblastic cells in the first trimester villi and that invaded to the deciduas. BeWo cells also expressed 14-3-3 tau. Down-regulation of 14-3-3 tau increased the invasive cell-number of BeWo, as well as the expression of snail, and inhibited E-cadherin. U0126 inhibited the enhanced invasiveness in these cells induced by the down-regulation of 14-3-3 tau. CONCLUSION: 14-3-3 tau may regulate the invasiveness of human trophoblastic cells through ERK1/2 signaling pathway.

Epithelial-mesenchymal transition (EMT) refers to tne transition during which epithelial cells undergo the loss of apical-basal polarity, acquisition of migration capability and transformation into mesenchymal cells. EMT induces breast cancer in situ to developing into metastasis and associates with the drug resistence. The multiple elements including signal pathways, transcriptional factors and downstream genes orchestrate the transition. Among them, the transforming growth factor β (TGF-β) signaling pathway plays a key role in the regulation of EMT in breast cancer. And this paper reviews the development of TGF-β signaling pathway induced EMT in breast cancer.

Objective To investigate the relationship between the exon 4 gene polymorphism of TIM-1 and rheumatoid arthritis (RA) in Han population from Hubei province.Methods Polymerase chain reaction was used to detect the ins/del polymorphism of the exon 4 of TIM-1 from RA population and the normal con- trols.Rheumatoid factor (RF),anti-cyclic citrullinated peptide (CCP) antibody and anti-keratin antibody (AKA) were also detected.Results Two alleles,a wild type del and a variant allele ins were identified in the TIM-1 exon 4.The genotype frequencies of del/del,ins/del and ins/ins were 0.650,0.280 and 0.070 respec- tively in the normal controls and 0.616,0.302,0.082 respectively in RA population.There was a significant correlation between the positive ratio of AKA and the genotypes of the exon 4.Conclusion The polymorphism of the exon 4 of TIM-1 is not associated with rheumatoid arthritis in Han population from Hubei Province of China.The genotypes of the exon 4 may have an effect on the expression of AKA.

Objective To investigate the correlation between obstructive sleep apnea syndrome(OSAS)with myocardial ischemia and arrhythmia.Methods To observe the occuring rate of premature beats and change of ST- segment,90 eases of OSAS patients were detected by the polysomnogram(PSG)and dynamic electrocardiogram at the same time.Results Total morbidity of myocardial ischemia was 32.2 % in OSAS patients,and it was 59.4 %, 15.8 %,20 % in serious,moderate and mild groups respectively.There was a statistically significant difference be- tween the three groups and the control group(P0.05).Conclusion As one of the risky factors of cardiovascular diseases,OSAS can induce myocardial ischemia and arrhythmia.

OBJECTSTo investigate the distribution of vitamin D receptor (VDR) genotypes among the Hans of a lead contaminated mine in Shanxi and explore the relationship between blood lead levels and the genetic polymorphism of VDR gene.

METHODSVDR genotypes were determined by polymerase-chain-reaction and restrictive fragment length polymorphism (PCR-RFLP) and the blood lead level was measured by using the graphite furnace atomic absorption spectrometry in a population of 120 pre-school children aged 5 - 6 years who were from the mine kindergarten and were unrelated Hans. An environmental questionnaire in relation to blood lead level was filled for each subject.

RESULTS(1) The gene distribution of the VDR phenotypes in these children was VDRBB, 1.7%; VDRBb, 9.2%; VDRbb, 89.2%. (2) The mean blood lead level of the children who had VDR B allele [(0.910 8 +/- 0.265 0) micromol/L] was significantly higher than that whose VDR genotype was bb [(0.740 1 +/- 0.270 1) micromol/L (mean +/- standard deviation)] (t = 2.155, P < 0.05). (3) Many factors were found to affect the blood lead levels, such as the VDR genotype, the type of fuel, educational level of mothers and so on. After controlling the possible confounding variables by multiple regression, the contribution of the VDR phenotype to the blood lead levels was still statistically significant.

CONCLUSIONThese results indicated that the frequency distribution of the VDR genotype in these children was apparently different from that in Caucasians who had high frequencies of VDR B. The results also indicated that the individuals carrying the VDR B allele were more susceptible to lead poisoning.

Objective To insestigate the pathophysiological mechanisms of spontaneous transient hyperperfusion after cerebral ischemia-reperfusion in rats.Methods Fifty-two SD rats were randomly allocated into sham-operation(group A),cerebral ischcmia 2-hour(group B), and cerebral ischemia 6-hour(group C)groups.Group B were redivided into 0-,0.5-,1-,2-,4-,6-,and 24-hour subgroups according to the reperfusion time;group C were redivided into 0-,0.5-,1-,2-,and 24-hour subgroups according to the reperfusion time (n=4 in each subgroup). Multislice spiral CT perfusion imaging(CTPI)was performed at different time points after ischemia-reperfusion in each group.After completing the scanning.the rats were sacrificed immediately for optical and electron microscopy examinations.Results In group A,compared to the contralateral sides.there were no significant differences in the relatise value of the cerebral blood flow parameters and the results of optical and electron microscopy in the sham-operated regions. In group B, the relative cerebral blood flow (rCBF) and relative cerebral blood volume (rCBV) in the ischemic core area were increased gradually with the extension of reperfusion time. The relative mean transit time (rMTT) and the relative time to peak (rTTP) were decreased gradually, There were no significant differences compared to group A at 6-hour after reperfusion. The optical and electron microscopy revealed that neuronal density in the ischemic core area in group B were decreased, part of the cell volume enlarged and showed vacuolated changes, and part of the neuronal cell bodies and nuclei shrinked, rCBF in the ischemic core area still maintained lower level with the extension of reperfusion time in group C. The ischemic core area showed the increased transient rCBV and rCBV at 0.5 hour after reperfusion in group B and C. The optical and electron microscopy showed that the ischemic core area presented a large number of necrotic and apoptotic cells, and inflammatory cell infiltration. At 6 hours after reperfusion in group B, the increased blood density was observed under the electron microscope in the ischemic core area, showing capillary engorgement and increased pressure. Conclusions The dynamic changes of CTPI in the process of rat middle cerebral artery occlusion and reperfusion have a certain correlation with the pathological mechanisms of injury. The ultra-early spontaneous and transient hyperperfusion after cerebral ischemia-reperfusion in rats is associated with the transient inflammatory hyperemia after reperfusion injury.

OBJECTIVETo study the dynamic changes in the protein marker expression in the spermatogonial stem cells (SSCs) of mice at different ages by iTRAQ protein mass spectrometry and to screen new markers using the bioinformatic proteome database.

METHODSBased on the postnatal weeks, we divided 80 healthy male C57BL/6 mice into eight age groups of equal number, harvested their testicular tissues, extracted proteins following purification of the SSCs by compound enzyme digestion and magnetic-activated cell sorting. Then we analyzed and identified proteins using two-dimensional electrophoresis, protein mass spectrometry, and protein database information.

RESULTSTotally, 248,510 mass spectra were obtained from the MS experiment and 1132 proteins were identified. By the criteria of >1.2-fold for protein abundance difference and P value <0.05, we identified 298 differentially expressed proteins and 9 currently known makers of SSCs (PCNA, GFRalpha1, CDH1, Annexin A7, UCHL1, VASA, CD49f, CD29, and PLZf). Compara- tive analysis showed different expressions of the proteins in the SSCs of the mice of different ages, and the differences in the expressions of GFRalpha1, CD49f, and CD29 were consistent with the findings in other published literature. Ten proteins (P63, CD71, CD98, K19, ACE, K18, K15, K17, SH2, and SH3) were selected as SSC markers to be further studied.

CONCLUSIONThe proteins in SSCs are differentially expressed in mice of different ages. The technology of iTRAQ protein mass spectrometry can be used to analyze and compare the proteome information of mouse SSCs, obtain differentially expressed proteins in mice of different ages, and thus offers a new ap- proach to further analysis and study of the function and roles of these differential proteins.
