ABSTRACT

The eukaryotic genome is folded into higher-order conformation accompanied with constrained dynamics for coordinated genome functions. However, the molecular machinery underlying these hierarchically organized three-dimensional (3D) chromatin architecture and dynamics remains poorly understood. Here by combining imaging and sequencing, we studied the role of lamin B1 in chromatin architecture and dynamics. We found that lamin B1 depletion leads to detachment of lamina-associated domains (LADs) from the nuclear periphery accompanied with global chromatin redistribution and decompaction. Consequently, the inter-chromosomal as well as inter-compartment interactions are increased, but the structure of topologically associating domains (TADs) is not affected. Using live-cell genomic loci tracking, we further proved that depletion of lamin B1 leads to increased chromatin dynamics, owing to chromatin decompaction and redistribution toward nucleoplasm. Taken together, our data suggest that lamin B1 and chromatin interactions at the nuclear periphery promote LAD maintenance, chromatin compaction, genomic compartmentalization into chromosome territories and A/B compartments and confine chromatin dynamics, supporting their crucial roles in chromatin higher-order structure and chromatin dynamics.

ABSTRACT

To investigate the therapeutic effect and mechanism of Qingfei oral liquid in idiopathic pulmonary fibrosis. Seventy-two male SD rats were divided into control group, model group, pirofenidone group and Qingfei group with 18 animals in each group. The idiopathic pulmonary fibrosis was induced in last three groups by intratracheal injection of bleomycin; pirofenidone group was given oral administration of pirofenidone b.i.d for 21 d, and Qingfei group was given Qingfei oral liquid 3.6 mL/kg q.d for Lung tissues were obtained for HE staining, Masson staining and transforming growth factor (TGF)-β immunohistochemical staining. Superoxide dismutase (SOD), malondialdehyde (MDA) and glutathione (GSH) were detected in tissue homogenates. The BATMAN-TCM database was used to retrieve the chemical components and their corresponding targets of Qingfei oral solution by network pharmacology method, and then the component-target-disease network diagram was constructed. Finally, the pathway enrichment analysis was carried out to explore the molecular mechanism of Qingfei oral liquid against idiopathic fibrosis. Histopathology results showed that Qingfei oral liquid had a similar relieving effect on pulmonary fibrosis as the positive drug pirfenidone; TGF-β secretion had a significant reduction in lung tissues of Qingfei group; and Qingfei oral liquid had better regulatory effect on SOD, MDA and GSH than pirfenidone. The results of component-target-disease network and pathway enrichment analysis showed that the related molecular pathways were concentrated in inflammation, extracellular matrix and cytokines. Qingfei oral liquid has a good therapeutic effect on idiopathic pulmonary fibrosis in rats via regulation of inflammation, extracellular matrix and cytokines.

ABSTRACT

Objective:To explore the potential of Taenia solium (Ts) 14-3-3.3 protein as a candidate molecule for cysticercosis vaccine. Methods:Sixty Kunming mice with the body weight of 18 - 22 g were selected and divided into 3 groups according to their body weight via the random number table method, including normal saline control group (control group), Ts14-3-3.3 recombinant protein vaccine group (vaccine group), and Ts14-3-3.3 recombinant protein vaccine + adjuvant group (vaccine + adjuvant group), with 20 mice in each group. The multi-point subcutaneous injection method was adopted. After the first immunization at 0 week, the booster immunization was carried out twice, a total of 3 times, with an interval of 2 weeks. Four mice in the three groups were killed at 0, 2, 4, 6 and 8 weeks after the first immunization, and the blood of eyeballs and spleen were collected aseptically for serum separation and preparation of spleen lymphocytes suspension [treatment: cell suspension, antigen-stimulate and concanavalin (Con) A-stimulate], respectively. The levels of mouse serum specific immunoglobulin (Ig) G, IgG2a, IgG1 and IgE were detected by indirect enzyme-linked immunosorbent assay (ELISA). The proliferation level of mouse spleen lymphocytes was detected via the CCK-8 method. The levels of tumor necrosis factor (TNF)-α, interleukin (IL)-12, IL-13 and IL-10 in culture supernatant of mouse spleen lymphocytes were determined by double-antibody sandwich ELISA.Results:The IgG, IgG2a, and IgG1 levels of the vaccine and vaccine + adjuvant groups immunized for 2 to 8 weeks were higher than those of the control group, and the above indicators of the vaccine + adjuvant group were higher than those of the vaccine group ( P < 0.05). With the same treatment between the groups, the proliferation levels of spleen lymphocytes and the levels of TNF-α, IL-12, IL-13, and IL-10 in the culture supernatant after 2 - 8 weeks of immunization were statistically significantly different ( P < 0.05); the proliferation levels of spleen lymphocytes and the levels of TNF-α, IL-12, IL-13 and IL-10 in the culture supernatant of the vaccine and vaccine + adjuvant groups immunized for 2 to 8 weeks were higher than those of the control group, and the above indicators of the vaccine + adjuvant group were higher than those of the vaccine group ( P < 0.05). When treatment was different in the group, the proliferation levels of spleen lymphocytes and the levels of TNF-α, IL-12, IL-13 and IL-10 in the culture supernatant of the antigen-stimulate and ConA-stimulate were higher than those of the cell suspension, and the above indicators of the ConA-stimulate were higher than those of the antigen-stimulate ( P < 0.05). Conclusion:The recombinant protein vaccine of Ts14-3-3.3 can induce an effective immune response in mice.

ABSTRACT

To investigate the molecular mechanism of resveratrol inhibiting the metastasis of liver cancer . HepG2 and Huh7 cells were treated with different concentrations of resveratrol, and the cell viability was determined by CCK-8 assay to determine the optimal concentration of resveratrol for subsequent experiments. The expressions of miR-186-5p in liver cancer tissues and liver cancer cells were determined by quantitative real-time RT-PCR. The migration and invasion of HepG2 and Huh7 cells were detected by wound healing assay and Transwell assay, and the expression levels of epithelial-mesenchymal transition (EMT) related proteins were determined by Western blotting. Resveratrol with concentration of had no effect on the viability of HepG2 and Huh7 cells, so the concentration of resveratrol in subsequent experiments was 6.25 μmol/L. Resveratrol inhibited the wound healing and invasion of liver cancer cells; increased the expression of E-cadherin, and decreased the expression of vimentin and Twist1. The expression of miR-186-5p was significantly down-regulated in liver cancer tissues and cells compared with the adjacent tissues and normal liver cells (both <0.05). Furthermore, resveratrol induced the expression of miR-186-5p in liver cancer cells (both <0.01). Overexpression of miR-186-5p suppressed the migration, invasion and EMT of liver cancer cells. Knockdown of miR-186-5p blocked the inhibition effects of resveratrol on the migration, invasion and EMT of liver cancer cells. Resveratrol could inhibit the metastasis of liver cancer , which might be associated with up-regulating miR-186-5p.

ABSTRACT

Ferroptosis is an iron-dependent programmed cell death characterized by reactive oxygen species-induced lipid peroxide accumulation, which is different from cell apoptosis, pyroptosis, necrosis or autophagy. Ferroptosis plays an important role in the regulation of tumorigenesis and tumor development. Recent studies have shown that natural medicinal ingredients can induce ferroptosis in tumor cells through glutathione (GSH)/glutathione peroxidase 4 (GPx4) pathway, iron metabolism, lipid metabolism or other mechanisms. It has been reported that more than 30 natural medicinal ingredients can induce ferroptosis in tumor cells with multiple pathways and multiple targets. This article reviews the current research progress on the antitumor effects of natural medicinal ingredients through inducing cell ferroptosis.

ABSTRACT

, a widely used Chinese herbal medicine, was considered as central nervous system (CNS) drug for years. Both ethanol extracts (EES) and water extracts (WES) of it were applied clinically. Unfortunately, the difference of their efficacy and even effective material foundation of remains obscure. In this study, to explore the active constituents of , we compared pharmacodynamics and chemical profiles / of EES/WES for the first time using multiple chemical analysis, pharmacological and data processing approaches. It was proved that there was no significant difference in the anti-depressive effects between WES and EES. However, the contents of most components and in plasma were higher in EES than those in WES, which was unconvincing for their similar efficacy. Therefore, we further explored components of targeted onto brain and the results showed that 5 lignans were identified with definite absorptivity respectively both in EES and WES caused by the limitation of blood-brain barrier. Moreover, bioinformatic analysis predicted their anti-depressive action. Above all, the systematic strategy screened 5 brain-targeted effective substances of and it was suggested that exploring the components into nidi would promote the studies on herbs effective material basis.

ABSTRACT

Trichoderma spp. is a kind of filamentous fungi with important biocontrol value. Twelve strains of Trichoderma spp. were isolated from the soils of different types of crops in Shaoxing, Zhejiang and Foshan, Guangdong. The antagonistic resistance to Fusarium oxysporum was compared by plate confrontation test. The further analysis of volatile secondary metabolites for two strains were carried out using HS-SPME-GC-MS analysis. The results showed that T. asperellum ZJSX5003 and GDFS1009 had fast growth ability, and the inhibition effects on F. oxysporum were 73% and 74% respectively. Six identical volatile metabolites were detected as follows 2-Methyl-1-propanol, 3-Methyl-1-butanol, 3-Methyl-3-buten-1-ol, Acetyl methyl carbinol, Butane-2,3-diol and 6-n-pentyl-2H-pyran-2-one (6-PAP). Among them, 6-PAP was validated to have a higher inhibitory effect on F. oxysporum in vitro. This study will provide basis for the development of biocontrol agents with metabolites of Trichoderma, such as 6-PAP.

ABSTRACT

OBJECTIVE: To identify the time dependent profiles of gene expression and featured co-expression network modules in peripheral blood of rats after middle cerebral artery occlusion (MCAO). METHODS: Microarray GSE119121 from GEO database was analyzed by R language to identify the significantly changed genes in peripheral blood at different time points (0, 1, 2, 3, 6 and 24 h) after MCAO. Gene expression patterns at different time courses were screened by STEM tools. Then, function annotation and pathway enrichment of differentially expressed genes (DEGs) were performed using the Gene Ontology (GO) database and the Kyoto Gene and Genomic Encyclopedia (KEGG) database. Depending on CEMiTool package, gene expression profile matrix was inputted into R to construct the co-expression networks and to analyze modules, and enrichment analysis was conducted to evaluate the correlation between the modules and different time points. RESULTS Comparing with gene at 0 h, the numbers of DEGs in peripheral blood at different time points after MCAO were 163 (1 h), 502 (2 h), 527 (3 h), 550 (6 h), and 75 (24 h), respectively. Moreover, a total of 38 gene expression patterns were enriched, and pattern 65 and pattern 34 were specifically up-regulated or down-regulated at 2-6 h. Hp, Nos2, P2ry10, and Klf12 were representative genes of these two models. The co-expression network module analysis showed that the gene status in the early acute phase (1-6 h) was positively correlated with the Module 2. Module 3 and Module 4 was positively correlated with phase phase 1-3 h and 2-6 h, respectively. Noteworthy, Module 6 gradually changed from positive correlation (0-2 h) to negative correlation (3-24 h) with the MCAO time course, and Module 6 was mainly related to viral response and innate immune response. The hub genes of Module 6 included Mx1, Mx2, and Rtp4. CONCLUSIONS Our study has identified the featured genes and dynamic co-expression network modules in peripheral blood after acute ischemic stroke, which provides a potential basis for judging the onset time of ischemic stroke.

ABSTRACT

Objective To explore the clinical significance of centralized surveillance of hydatidiform mole.Methods From Feb.2013 to Feb.2017 all patients with hydatidiform mole,who underwent suction curettage and were confirmed by histopathology in Dalian Maternal and Child Health Care Hospital,were registered centrally for serum hCG monitoring and treatment if necessary.Prophylactic chemotherapy was not administered regardless of risk factors for malignant transformation of hydatidiform mole.The risk factors included age of over 40 years,excessive uterine enlargement for presumed gestational age,a serum hCG level greater than 5 00 000 U/L,large theca lutein ovarian cysts (>6 cm),and a history of previous hydatidiform mole.The centralized surveillance of hydatidiform mole was based on the central pathology review,team cooperation and service improvement.Their treatments and outcomes were analyzed retrospectively.Results A total of 407 women of hydatidiform mole were registered with histopathology confirmation,including 70 high-risk hydatidiform moles.The follow-up rate was 97.5% (397/407).The incidence of post-mole neoplasia was 8.1% (32/397),which was diagnosed in 22.9% (16/70) of high-risk and in 4.9% (16/327) of low-risk hydatidiform moles,showed statistically significant difference between high-risk and low-risk groups (x2=25.108,P<0.01).Thirty-two patients with post-mole neoplasia were all at low risk of International Federation of Gynecology and Obstetrics (FIGO) score (range,0-6) and received complete remission with chemotherapy alone in 31 of them except one treated by hysterectomy.The primary cure rate of single-agent chemotherapy was 60.0% (18/30).Patients with low-risk or high-risk post-mole neoplasia were both 16.There were no significant differences between the two groups in interval that was end of antecedent pregnancy to start of treatment,the serum level of hCG before treatment,clinical stage or risk factor score (all P>0.05).Conclusions The risk of malignant transformation is increased in high-risk hydatidiform mole,however,the high risk factor itself does not affect the prognosis in patients with timely diagnosis and treatment of post-mole neoplasia.Therefore,prophylactic chemotherapy is not recommended to high-risk hydatidiform mole patients.Centralized surveillance of hydatidiform mole is practical in a local hospital of China and could greatly improve the prognosis of post-mole neoplasia.
