Conclusion The expression of CHKA in glioma tissue is significantly higher than that in the normal brain tissue, and knockdown of CHKA gene inhibits the proliferation, invasion and migration of glioma cells. It suggests that CHKA may be related to the occurrence and development of gliomas.Objective To observe the changes of the acetylation of lysine 9 on histone H3 (H3K9) and H3K14 in the different brain regions during rapid eye movement after sleep deprivation (SD) in rats. Methods Modified multiple platform was used to establish the SD model. Forty-eight rats were randomly divided into four groups control group, one day post-SD group (SD1), three day post-SD group (SD3) and six day post-SD group (SD6). Western blotting was performed to examine the changes in the acetylation levels of H3K9 and H3K14 in different brain regions, including hippocampus, hypothalamus, prefrontal cortex and raphe nucleus. Results Compared with the control group, in the SD1, SD3, and SD6 groups, the acetylation levels of H3K9 and H3K14 in the hippocampus and hypothalamus significantly decreased time-dependently. In contrast, their levels in the ventromedial prefrontal cortex and raphe nucleus markedly increased in the SD6 but not in the SD1 and SD3 groups. Conclusion The increase of H3K9 and H3K14 acetylation in the hippocampus and hypothalamus as well as the decrease of H3K9 and H3K14 acetylation in the prefrontal cortex and raphe nucleus may be involved in the development of sleep disorders.Objective To investigate the effect of Yiqihuoxue herb Naoluoxintong on cerebral vascular regeneration in rats of middle cerebral artery occlusion-reperfusion(MCAO-R)experimental model with Qi deficiency and blood stasis syndrome, and explore the possible mechanisms. Methods A total of 60 SD rats were randomly divided into a control group, a model group and three Naoluoxintong-treated groups [(1 200, 800 and 400 mg/(kg.d)], with 12 rats each. Except for the control group, the other groups were treated with modified suture method combined with multi-factor compound simulation to establish the models with both MCAO-R and syndrome of Qi deficiency accompanied by blood stasis. Neural functional deficit, blood stasis syndrome and Qi deficiency syndrome were scored by quantitative criteria for biological characteristics score. The regional cerebral blood flow (rCBF) was dynamically monitored with laser Doppler scanning. HE staining was used to observe the pathological changes of brain tissue. The mRNA expression lesion of pro-angiogenic factors that are affected by Wnt signal path activation.Objective To elucidate the mechanisms by which elongation factor Tu GTP binding domain containing 2 (Eftud2) enhances the immune function of murine macrophages by bioinformatics analysis. Methods The bone marrow-derived macrophages (BMDMs) of Eftud2 myeloid cell-specific knockout (MKO) mice (n=10) and wild-type (WT) littermates (n=10) were collected and stimulated by lipopolysaccharide (LPS) (100 ng/mL) for 2 hours. Bioinformatics analysis was conducted to examine the differences in gene expression and mRNA transcription levels. The the differences in gene expression and alternative splicing of mRNA transcription in BMDMs were analyzed by DEGseq and rMATS, respectively. The signaling pathways affected were clarified by Kyoto Encyclopedia of Genes and Genomes (KEGG) classification and enrichment methods. Results Compared with WT counterparts, the expression levels of IL-6, IL-1β, TNF-α, and the genes related to immune response in MKO BMDMs were down-regulated following LPS stimulation. KEGG pathway analysis sh.Objective To detect the expression of chemokine and adhesion molecules related to leukocytes' transendothelial migration, meanwhile, to investigate changes of reticular fibers and the expression of vimentin and matrix metalloproteinase-9 (MMP9) in lung tissues after surgical removal of mouse tumor-bearing lymph node, revealing their changes and roles in the formation of pre-metastatic microenvironment in the lung. Methods B16F10 melanoma cells were inoculated into mouse subiliac lymph node (SiLN). Twenty mice were equally divided into groups with or without (as a control group) tumor-bearing SiLN removal. Fifteen days later, tumor-bearing lymph node was surgically removed; 3 days after resection, mouse lung tissues were collected. The change of reticular fibers in lung tissues was observed by silver impregnation staining. 6-Thio-dG manufacturer The expression of C-C motif chemokine ligand 4 (CCL4), intercellular adhesion molecule-1 (ICAM-1), vascular cell adhesion molecule-1 (VCAM-1), vimentin and MMP9 in lung tissues was detected by Western blotting. Results Compared with control group, expression of MMP9 and vimentin increased significantly in the lung tissues of SiLN removal group; reticular fibers were obviously fractured and its per area was reduced. Moreover, expression of CCL4, ICAM-1 and VCAM-1 also significantly increased. Conclusion Expression of CCL4, ICAM-1, VCAM-1, MMP9 and vimentin in mouse lung tissues is promoted after surgical removal of tumor-bearing lymph node, contributing to inflammatory cells' adhesion to and extravasation across vascular endothelium and further resulting in the formation of inflammatory microenvironment.Objective To investigate the effects of isochlorogenic acid A on the proliferation, migration, invasion and apoptosis of MH7A cells. Methods Following by the induction of 20 μg/L TNF-α in vitro, different concentrations of isochlorogenic acid A (0, 0.04, 0.09, 0.13, 0.16, 0.20 μg/μL) were added into MH7A cells. The proliferation of MH7A cells was detected by CCK-8 assay, and the invasion and migration were observed by TranswellTM assay. The levels of cellular caspase-3, ROS and MMP3 in the MH7A cells were detected by corresponding kits. BAX and Bcl2 expression of MH7A cells were tested by immunofluorescence cytochemistry. Results The proliferation, invasion and migration activity were enhanced significantly and the apoptotic activity was reduced in MH7A cells induced by 20 μg/L TNF-α. Compared with TNF-α in vitro induction, isochlorogenic acid A significantly inhibited the proliferation, invasion, migration and MMP3 secretion of MH7A cells, increased ROS release and promoted MH7A apoptosis. Conclusion Isochlorogenic acid A can inhibit proliferation, invasion, migration and promoted apoptosis of MH7A cells.
