Objective To investigate the expression level of basic leucine zipper and W2 domain-containing protein 1(BZW1)in gastric cancer,its impact on patient prognosis and the underlying mechanisms.Methods TIMER,UALCAN and Kaplan-Meier Plotter databases were used for analyzing BZW1 expression level gastric cancer tissues and its correlation with tumor grade and stage and the patients'prognosis.We further analyzed BZW1 expressions,disease progression,and postoperative 5-year survival in 102 patients undergoing radical surgery for gastric cancer at our hospital between January,2014 and December,2016.Gastric cancer MGC803 cells were examined for changes in migration,invasion,and epithelial-mesenchymal transition(EMT)following lentivirus-mediated BZW1 overexpression or knockdown.Results The protein and mRNA expressions of BZW1 in gastric cancer tissues were 3.30 and 6.54 times of those in adjacent tissues,respectively(P<0.01).BZW1 expression in gastric cancer tissues were positively correlated with peripheral blood CEA and CA199 levels(P<0.01).A high BZW1 expression was an independent risk factor for 5-year survival of gastric cancer patients after radical surgery(P<0.05,HR=2.070,95%CI:1.021-4.196).At the cut-off value of 3.61,BZW1 expression had a sensitivity of 75.56%and a specificity of 71.93%for predicting postoperative 5-year mortality(P<0.01).In MGC803 cells,BZW1 overexpression obviously promoted cell migration and invasion(P<0.05),enhanced cellular expressions of N-cadherin and vimentin(P<0.05)and inhibited the expression of E-cadherin(P<0.05).Enrichment analysis suggested the involvement of BZW1 in the Wnt/β-catenin signaling pathway.Western blotting confirmed that BZW1 overexpression promoted while BZW1 knockdown inhibited the expressions of Wnt3a,β-catenin and C-myc in MGC803 cells(P<0.05).Conclusion BZW1 is highly expressed in gastric cancer tissues to affect the patient prognosis possibly by activation the Wnt/β-catenin signaling pathway to promote EMT of gastric cancer cells.

In this study, ultra-performance liquid chromatography-quadrupole-time-of-flight tandem mass spectrometry(UPLC-Q-TOF-MS~E) was used to analyze the plasma components of Danzhi Xiaoyao Formula after oral administration. Forty-nine plasma components were found in the serum of rats by comparing the compound extract, drug-containing serum, and blank serum. Components, such as 6-hydroxycoumarin, poricoic acid F, deoxoglabrolide, 30-norhederagenin, kanzonol R, 3',6'-di-O-galloylpaeoniflorin, 16α-hydroxytrametenolic acid, 16-deoxyporicoic acid B, 3-O-acetyl-16α-hydroxytrametenolic acid, and 16α,25-dihydroxydehydroeburiconic acid, were first found in rat serum. Behavioral tests, including the tail suspension test, novel object recognition test, and novelty-suppressed feeding test, were conducted for behavioral analysis. It was confirmed that this formula had therapeutic effects on perimenopausal depression. Furthermore, in combination with the network pharmacology method, 53 core targets including MAPK1, HRAS, AKT1, EGFR, and ESR1 were screened, and these targets participated in 165 signaling pathways, including PI3K-AKT, AMPK, VEGFA, MAPK, and HIF-1. In summary, the potential effects of Danzhi Xiaoyao Formula in treating perimenopausal depression are associated with mechanisms in accelerating inflammation repair, improving neuroplasticity, affecting neurotransmitters, regulating estrogen levels, and promoting new blood vessel formation.

OBJECTIVE:
To investigate the expression of four-jointed box kinase 1 (FJX1) in gastric cancer (GC), its correlation with survival outcomes of the patients, and its role in GC progression.
METHODS:
The expression level of FJX1 in GC tissues and normal gastric mucosal tissues and its correlation with the survival outcomes of GC patients were analyzed using TCGA and GEO database GC cohort. Immunohistochemistry was used to detect FJX1 expression level in clinical specimens of GC tissue, and its correlations with the patients' clinicopathological parameters and prognosis were analyzed. Bioinformatic analysis was performed to identify the potential pathways of FJX1 in GC. The effects of FJX1 overexpression or FJX1 silencing on GC cell proliferation and expressions of proliferation-related proteins, PI3K, AKT, p-PI3K, and p-AKT were evaluated using CCK-8 assay and Western blotting. The effect of FJX1 overexpression on GC cell tumorigenicity was evaluated in nude mice.
RESULTS:
GC tissues showed significantly higher expressions of FJX1 mRNA and protein compared with normal gastric mucosa tissues (P < 0.05). The high expression of FJX1 was associated with poor prognosis of GC patients (P < 0.05) and served as an independent risk factor for poor survival outcomes in GC (P < 0.05). FJX1 was expressed mainly in the cytoplasm of GC cells in positive correlation with Ki67 expression (R=0.34, P < 0.05), and was correlated with CA199 levels, depth of tumor infiltration and lymph node metastasis of GC (P < 0.05). In the cell experiment, FJX1 level was shown to regulate the expressions of Ki67 and PCNA and GC cell proliferation (P < 0.05). Gene set enrichment analysis indicated that the PI3K/AKT pathway potentially mediated the effect of FJX1, which regulated the expressions of PI3K and AKT and their phosphorylated proteins. In nude mice, FJX1 overexpression in GC cells significantly promoted the growth of the transplanted tumors (P < 0.05).
CONCLUSION
FJX1 is highly expressed in GC tissues and is correlated with poor prognosis of GC patients. FJX1 overexpression promotes GC cell proliferation through the PI3K/AKT signaling pathway, and may serve as a potential prognostic biomarker and therapeutic target for GC.

This study aims to identify the active components and the mechanism of Jingqi Yukui Capsules(JQYK) in the treatment of gastric ulcer based on network pharmacology, and verify some key targets and signaling pathways through animal experiment. To be specific, first, the active components and targets of JQYK were retrieved from a Bioinformatics Analysis Tool for Molecular Mechanism of Traditional Chinese Medicine(BATMAN-TCM) and Traditional Chinese Medicine Systems Pharmacology Database and Analysis Platform(TCMSP), and the targets of gastric ulcer from GeneCards and Online Mendelian Inheritance in Man(OMIM) with the search term "gastric ulcer". The common targets of the two were the potential targets of the prescription for the treatment of the di-sease. Then, protein-protein interaction(PPI) network of key targets were constructed based on STRING and Cytoscape 3.7.2, followed by Kyoto Encyclopedia of Genes and Genomes(KEGG) pathway enrichment by matescape database and pathway visualization by Omicshare. For the animal experiment, the improved method of Okabe was used to induce gastric ulcer in rats, and the model rats were classified into the model group, JQYK high-dose(JQYK-H), medium-dose(JQYK-M), and low-dose(JQYK-L) groups, Anweiyang Capsules(WYA) group, and Rabeprazole Sodium Enteric Capsules(RBPZ) group. Normal rats were included in the blank group. Rats in the blank group and model group were given distilled water and those in the administration groups received corresponding drugs. Then gastric ulcer healing in rats was observed. The changes of the gastric histomorphology in rats were evaluated based on hematoxylin-eosin(HE) staining, and the content of inducible nitric oxide synthase(iNOS) in rat gastric tissue was detected with Coomassie brilliant blue method. The mRNA and protein levels of some proteins in rat gastric tissue were determined by real-time quantitative polymerase chain reaction(RT-qPCR) and Western blot(WB) to further validate some key targets and signaling pathways. A total of 206 active components and 535 targets of JQYK, 1 305 targets of gastric ulcer, and 166 common targets of the disease and the drug were yielded. According to PPI analysis and KEGG pathway enrichment analysis, multiple key targets, such as interleukin-6(IL-6), tumor necrosis factor(TNF), mitogen-activated protein kinase 1(MAPK1), MAPK3, and MAPK14, as well as nuclear factor kappa-B(NF-κB) signaling pathway, IL-17 signaling pathway, and leukocyte transendothelial migration in the top 20 key signaling pathways were closely related to inflammation. The key protein p38 MAPK and NF-κB signaling pathway were selected for further verification by animal experiment. The gastric ulcer in the JQYK-H group recovered nearly to the level in the blank group, with significant decrease in the content of iNOS in rat gastric tissue and significant reduction in the mRNA and phosphorylation levels of p38 MAPK and the mRNA and protein levels of NF-κB p65 in rat gastric tissue. The results indicated that JQYK can inhibit the phosphorylation of the key protein p38 MAPK and the expression of NF-κB p65 in the NF-κB signaling pathway, thereby exerting the anti-inflammatory effect and effectively improving the quality of gastric ulcer healing in rats. Thus, the animal experiment result verifies some predictions of network pharmacology.
