AIM: To determine whether the eukaryotic initiation factor-4E (eIF-4E) inhibition facilitates the degradation of heparanase mRNA and alters heparanase protein expression in human colon adenocarcinoma cell line, LS-174T. METHODS: A 20-mer antisense s-oligodeoxynucleotide (asODN) targeted against the translation start site of eIF-4E mRNA were introduced into LS-174T cells by lipid-mediated DNA-transfection. eIF-4E protein and mRNA levels were detected by Western blot and RT-PCR, respectively. The mRNA levels of heparanase were determined by Northern blot. The alterations of heparanase expression were confirmed by Western blot analysis. RESULTS: The 20-mer asODN against eIF-4E specifically and significantly inhibited eIF-4E protein expression. Following eIF-4E inhibition, a significant reduction of heparanase mRNA was observed on Northern blot, and at the same time, heparanase protein expression significantly decreased as well. CONCLUSIONS: The results indicate that the inhibition of eIF-4E strongly reduces the stability of heparanase mRNA in colon adenocarcinoma cell line, LS-174T and resultes in an apparent reduction in the expression of heparanase protein.

OBJECTIVETo analyze the correlation between environmental factors and the lipophilic and hydrophilic constituents of Polygalae Radix.

METHODThe contents of lipophilic constituent were determined by GC-MS and hydrophilic constituents by HPLC. Geographical factors were collected by on-site inspection and climate factors by the local meteorological data. The relationship between the content of the lipophilic and hydrophilic constituents and the factors were analyzed by SPSS 18.0.

RESULTThere was linear relationship between the content of lipophilic constituent and climate factors such as average temperature of July, average temperature of January. There was also linear relationship between hydrophilic constituents and climate factors such as annual average temperature, latitude, annual average rainfall.

CONCLUSIONThe main climate factors that affect liposoluble constituent content were average temperature of July, average temperature of January, and the main climate factors that affect hydrophilic constituent content were annual average temperature, latitude, annual average rainfall. The study would contribute to the quality evaluation and suitability of origin of Polygalae Radix.

Objective To evaluate the association between site polymorphism of glutathione S-transferase omega1 (GSTO1) gene (rs4925),arsenic (+3) methyhransferase (As3MT) gene (rs11191439) and susceptibility to endemic arsenic poisoning.Methods All related studies in published papers up to March 1,2018 on association between site polymorphism of As3MT gene,GSTO1 gene and susceptibility to endemic arsenic poisoning were collected by searching PubMed,Embase,CNKI,Wanfang and VIP database.The data were screened according to the inclusion and exclusion criteria,and extracted,the quality of included studies was evaluated.The pooled odds ratios (OR) with 95％ confidence intervals (95％CI) were calculated using Review Manager 5.3 software.Publication bias and sensitivity analysis were also assessed.Results A total of 7 case-control studies involving 989 cases and 1 212 controls were included in the Meta-analysis.Individuals carrying at least one allele A at the rs4925 locus of the GSTO1 gene might increase the risk of susceptibility to arsenic poisoning compared with individuals carrying wild homozygous type [AA + CA vs CC,OR (95％CI) =1.37 (1.13,1.65),P ＜ 0.01].There was no statistically significant relationship between susceptibility to arsenic poisoning in individuals with at least one allele C at the rs1 1191439 locus of the As3MT gene compared with individuals carrying wild homozygous type [CC + TC vs TT,OR (95％CI) =1.12 (0.69,1.81),P ＞ 0.05].Conclusions GSTO1 gene rs4925 polymorphism is significantly associated with susceptibility to arsenic poisoning,and the A allele is a risk gene for susceptibility to arsenic poisoning.The As3MT gene rs1 1191439 locus polymorphism is not associated with susceptibility to arsenic poisoning.

Objective:To investigate the effect of SCN1A gene polymorphism (SCN1A-rs3812718) on the alterations of spontaneous brain activity using amplitude of low-frequency fluctuations (ALFF) of MR in patients with temporal lobe epilepsy (TLE).Methods:A total of 37 TLE patients (TLE group) admitted to the Epilepsy Center of the 900th Hospital of Joint Logistic Team from March 2018 to August 2019 were retrospectively analyzed, and another 28 healthy volunteers matched for gender, age, and years of education with the TLE group were selected as the healthy control group (HC group). Sixty-five subjects were divided into four groups by genotype and diagnosis: 34 cases in AA/AG-TLE subgroup, 3 cases in GG-TLE subgroup, 20 cases in AA/AG-HC subgroup and 8 cases in GG-HC subgroup. All subjects underwent sagittal 3D-T 1WI and resting-state functional MRI using a Siemens 3.0 T Trio Tim MR scanner. Then ALFF values of the four groups were calculated using DPABI by the MATLAB 2010 platform. The ALFF values between two groups were compared by independent samples t-test. The ALFF values of different genotypes at rs3812718 locus in TLE and HC group were analyzed by multivariate analysis of variance to find out the corresponding brain regions with interaction, and then post hoc simple effect analysis was performed. Results:The ALFF values in TLE group significantly increased in left marginal lobe, left parahippocampal gyrus, left fusiform gyrus, left hippocampus, right insular lobe and right inferior temporal gyrus (Alphasim corrected P<0.001) and decreased in the left superior frontal gyrus, left middle frontal gyrus, left inferior frontal gyrus, right middle frontal gyrus, right precuneus, left precuneus, bilateral cingulate gyrus and right angular gyrus (Alphasim correction P<0.05) compared with HC group. Subjects carrying the non-risk G allele had higher ALFF values in the right inferior temporal gyrus, right fusiform gyrus, and right cerebellum than subjects carrying the risk A allele ( t=3.30, Alphasim corrected P=0.002). There was a significant interaction effect on posterior cerebellar lobe, left anterior cerebellar lobe, left inferior temporal gyrus, left superior parietal lobule and right precuneus of TLE patients with SCN1A-rs3812718 genotype. Post-hoc simple effect analysis showed that ALFF significantly increased in the left posterior cerebellar lobe, left anterior cerebellar lobe, left inferior temporal gyrus and left fusiform gyrus in GG-TLE subgroup ( t=5.97, P<0.001), but significantly decreased in the right superior parietal lobule, right precuneus, right posterior cerebellar lobe in AA/AG-TLE subgroup compared to the HC group. Compared with GG-TLE subgroup, ALFF in left posterior cerebellar lobe, left fusiform gyrus and left inferior temporal gyrus decreased in AA/AG-TLE subgroup. Conclusion:SCN1A gene polymorphism in the rs3812718 locus affects spontaneous neural activity in resting state, which may be one of the pathophysiological mechanisms of TLE.

Objective:To explore the mechanism of miR-205-5p/E2F1 signal axis in regulating the glioma U251, U87 radiotherapy resistance.Methods:X-ray gradual ascending and intermittent induction method was used to irradiate the glioma U251 cells to establish U251/TR, U87/TR radiation-resistant cell lines. Then, the morphology, migration, invasion and proliferation abilities of cells (U251/TR, U87/TR radiation-resistant cells and U251, U87 radiation-sensitive cells) were analyzed. Luciferase gene detection system and point mutation technique were employed to analyze the mechanism of miR-205-5p and E2F1 gene activity on U251 and U87 radiation-resistant cell lines.Results:Compared with the radiation-sensitive U251 cells, the radiation-resistant cells U251/TR, U87/TR showed increased proliferation activity, enhanced migration and invasion abilities and decreased apoptosis under X-ray irradiation. miR-205-5p mimics transfection could down-regulate the expression of E2F1 factor in U251/TR cells, inhibit cell proliferation, invasion and migration and increase the radiosensitivity of U251/TR cells. miR-205-5p mimics transfection combined with with E2F1 down-regulation exerted anti-tumor effect and decreased cell tolerance by suppressing the Wnt/β-catenin signaling pathway activity.Conclusions:The glioma radiation-resistant cell line U251/TR, U87/TR can be established by X-ray gradual ascending and intermittent induction method. The miR-205-5p/E2F1 signal axis exerts tumor-suppressing effect through the classical Wnt/β-catenin signaling pathway, which can be used as an therapeutic target to increase the radiosensitivity of glioma.
