Objective:To investigate the effect of salidroside on the proliferation and invasion of prostate cancer PC-3M cells and the possible molecular mechanism.Methods:PC-3M cells were treated with different concentrations (0, 50, 100, 150, 200 nmol/L) of salidroside for 48 h, and MTS assay was used to detect the effect of salidroside on the proliferation of PC-3M cells. The PC-3M cells treated with the most obvious inhibitory effect concentration of salidroside were selected as the salidroside group, and the PC-3M cells treated with 0.9% NaCl were selected as the control group. Transwell assay was used to detect the effect of salidroside on PC-3M cell invasion. The expression difference of LINC01207 between prostate cancer tissues and adjacent tissues was analyzed by using GEPIA database. Real-time quantitative polymerase chain reaction (qRT-PCR) was used to detect the expression of LINC01207 and miR-1182 in PC-3M cells after salidroside treatment. Western blot was used to detect the expressions of proliferation and invasion related proteins in PC-3M cells after salidroside treatment.Results:After treated with 0, 50, 100, 150, and 200 nmol/L salidroside, the absorbance values of prostate cancer PC-3M cells were 0.98±0.17, 0.72±0.08, 0.47±0.10, 0.12±0.03, and 0.42±0.05, respectively, and the difference was statistically significant ( F = 42.02, P < 0.05); and 150 nmol/L salidroside had the most significant inhibitory effect. The salidroside group (150 nmol/L salidroside) was performed to do the subsequent experiment. The invasion number of PC-3M cells in the control group and the salidroside group were (80±11) and (36±13), respectively ( t = 5.15, P < 0.05). GEPIA database online analysis showed that the expression of LINC01207 in prostate cancer tissues was higher than that in paracancerous tissues ( P < 0.01). qRT-PCR results showed that the relative expression level of LINC01207 in PC-3M cells of the control group and the salidroside group was (6.2±1.1) and (1.2±0.7), respectively; and the expression of LINC01207 in PC-3M cells of the salidroside group was lower than that of the control group ( t = 7.88, P < 0.01). The relative expression level of miRNA-1182 was (1.00±0.20) and (7.02±0.35), respectively; the expression of miRNA-1182 in PC-3M cells of the salidroside group was higher than that of the control group ( t = 30.07, P < 0.01). Western blot results showed that after PC-3M cells were treated with salidroside, the expressions of cell proliferation proteins CDK2 and cyclin E decreased; the expressions of cell invasion proteins CD147, matrix metalloproteinases (MMP)-2, MMP-9 decreased. Conclusions:Salidroside inhibits prostate cancer PC-3M cell proliferation and invasion by downregulating LINC01207 expression and activating miRNA-1182 expression.

Objective:To explore the expression of microRNA (miRNA)-6516-5p in renal cancer cell lines and the molecular mechanisms regulating the proliferation and migration of renal cancer cells.Methods:quantitative real-time polymerase chain reaction (qRT-PCR) was used to detect the expression of miR-6516-5p in renal cancer cell lines and normal proximal renal tubular epithelial cell lines. The liposome method was used to transiently transfect miR-6516-5p mimic and nonsense sequence (NC) into renal cancer cells with the lowest expression of miR-6516-5p, namely miR-6516-5p group and NC group. qRT-PCR was used to detect the expression of miR-6516-5p in transfected cells. CCK-8 and Transwell migration experiment were used to detect the proliferation and migration of transfected cells. Bioinformatics software and dual luciferase gene report experiment were used to predict and verify the regulation of miR-6516-5p on target gene, respectively. qRT-PCR and Western blotting were used to detect the expression of target gene in transfected cells. Measurement data were expressed as mean±standard deviation ( ± s), t-test was used for comparison between two groups, and one-way analysis of variance was used for comparison between multiple groups. Results:The expression of miR-6516-5p in renal cancer cell lines was significantly lower than that of normal proximal tubular epithelial cells ( P<0.01), and the expression of miR-6516-5p in 786-O cells was the lowest ( F=27.69, P<0.01). The expression of miR-6516-5p in 786-O cells in NC group and miR-6516-5p group was 1.01±0.08 and 9.91±1.16, respectively. Compared with the NC group, the expression of miR-6516-5p in 786-O cells in the miR-6516-5p group was significantly increased ( t=7.63, P<0.01). Up-regulation of miR-6516-5p can significantly inhibit the proliferation of 786-O cells ( P<0.05). The migration numbers of NC group and miR-6516-5p group were 85.65±8.77 and 28.05±6.20, respectively. Overexpression of miR-6516-5p could inhibit the migration of 786-O cells ( t=5.36, P< 0.01). The target gene of miR-6516-5p may be ornithine decarboxylase 1 ( ODC1), miR-6516-5p can significantly inhibit the luciferase activity of wild-type ODC1-3′UTR ( t=9.83, P<0.01). Up-regulation of miR-6516-5p can reduce the expression of ODC1 mRNA and protein in 786-O cells ( P<0.01). Conclusion:The expression of miR-6516-5p is reduced in renal cancer cell lines, miR-6516-5p inhibits the proliferation and migration of renal cancer 786-O cells by targeting ODC1, miR-6516-5p may become a potential molecular target of renal cancer.

Flow cytometry was used to detect DU145 cell cycle changes. MTT proliferation test was used to detect the proliferation of DU145 cells. quantitative real-time polymerase chain reaction (qRT-PCR) was used to detect the expression of miR-380-3p in DU145 cells. The bioinformatics software RNAhybrid was used to predict the target genes of miR-380-3p. qRT-PCR and Western blotting methods were used to detect the expression of miR-380-3p target gene. Measurement data were expressed as mean ± standard deviation ( ± s), t-test was used for comparison between two groups. Results:Compared with the control group, DU145 cells in the physcion group were blocked in the G 0/G 1 phase ( P<0.01), and the proliferation ability of DU145 cells was significantly inhibited ( P<0.05). The expression of miR-380-3p in DU145 cells in the control group and physcion group was 8.36 ± 1.42 and 1.08 ± 0.39, respectively. Physcion could promote the expression of miR-380-3p ( t=4.96, P<0.01). The functional target gene of miR-380-3p may be UHRF1. The relative expression levels of UHRF1 mRNA in DU145 cells in the physcion group and control group were 0.23±0.06 and 1.04±0.15, respectively. Compared with the control group, the expression of UHRF1 gene in DU145 cells in the physcion group was decreased ( t=4.55, P<0.01).

Objective:To investigate the effects of astragalin on the cell proliferation and cell cycle of prostate cancer cell line C4-2B through up-regulating the expression of miRNA-513 (miR-513).Methods:Prostate cancer cell line C4-2B cells were taken and treated with 125 μg/L of astragalin for 48 h (astragalin group), and untreated C4-2B cells were set as the control group. The methyl thiazolyl tetrazolium (MTT) method was used to detect the proliferation ability of C4-2B cells in the two groups, and cell cycle was detected by using flow cytometry. The miRNAMap prediction software was used to predict that the targeted gene of miR-513 was the forkhead box protein R2 (FOXR2), and the dual luciferase gene reporter assay was used to verify it. Real-time fluorescent quantitative polymerase chain reaction (qRT-PCR) was used to detect the relative expression levels of miR-513 and FOXR2 mRNA in the two groups of cells. Western blotting was used to detect the expressions of FOXR2, cyclin-dependent kinase 7 (CDK7), β-actin and cyclin H in the two groups of C4-2B cells.Results:Compared with the control group, the proliferation activity of C4-2B cells in the astragalin group was decreased from day 2 to day 5 (all P < 0.05). The proportions of S-phase cells in the control group and the astragalin group were (48.1±3.2)% and (36.0±2.1)%, respectively. The proportion of S-phase cells in the astragalin group was decreased ( t = 3.12, P = 0.021); the proportions of G 2-phase cells were (24.9±3.3)% and (11.8±2.4)%, respectively. The proportion of G 2-phase cells in the astragalin group was decreased ( t = 3.18, P = 0.019). The relative expression levels of miR-513 in C4-2B cells of the control group and the astragalin group were 1.01±0.22 and 6.55±0.61, respectively. The relative expression levels of miR-513 in C4-2B cells in the astragalin group was increased ( t = 7.70, P < 0.01). The dual luciferase reporter gene assay verified that FOXR2 was the targeted gene of miR-513. The relative expression level of FOXR2 mRNA in C4-2B cells of the control group and the astragalin group was 1.04±0.14 and 0.19±0.06, respectively, and the difference was statistically significant ( t = 5.53, P = 0.002), suggesting that after astragalin promoted the expression of miR-513, the FOXR2 mRNA expression was decreased. The relative expression levels of FOXR2, CDK7 and cyclin H protein in C4-2B cells in the astragalin group were all decreased compared with those in the control group. Conclusions:Astragalin inhibits the proliferation of prostate cancer C4-2B cells and induces cell cycle arrest by up-regulating the expression of miR-513.

Glycolytic metabolism enzymes have been implicated in the immunometabolism field through changes in metabolic status. PGK1 is a catalytic enzyme in the glycolytic pathway. Here, we set up a high-throughput screen platform to identify PGK1 inhibitors. DC-PGKI is an ATP-competitive inhibitor of PGK1 with an affinity of K _d = 99.08 nmol/L. DC-PGKI stabilizes PGK1 in vitro and in vivo, and suppresses both glycolytic activity and the kinase function of PGK1. In addition, DC-PGKI unveils that PGK1 regulates production of IL-1β and IL-6 in LPS-stimulated macrophages. Mechanistically, inhibition of PGK1 with DC-PGKI results in NRF2 (nuclear factor-erythroid factor 2-related factor 2, NFE2L2) accumulation, then NRF2 translocates to the nucleus and binds to the proximity region of Il-1β and Il-6 genes, and inhibits LPS-induced expression of these genes. DC-PGKI ameliorates colitis in the dextran sulfate sodium (DSS)-induced colitis mouse model. These data support PGK1 as a regulator of macrophages and suggest potential utility of PGK1 inhibitors in the treatment of inflammatory bowel disease.

The expression of AC068768.1 in OS-RC-2 cells in the AC068768.1 group was significantly higher than that in the control group, the difference was statistically significant ( P<0.01). Up-regulating the expression of AC068768.1 can inhibit the cycle ( P<0.05) and proliferating ability ( P<0.05) of renal cancer cells. miR-21-5p may be the functional target gene of AC068768.1. Up-regulation of AC068768.1 can significantly inhibit the expression of miR-21-5p ( P<0.01) and promote the expression of tissue inhibitor of metalloproteinase 3 (TIMP3) ( P<0.01). Conclusion:AC068768.1 promotes the expression of TIMP3 gene by regulating the expression of miR-21-5p, thereby inhibiting the cell cycle and proliferation of renal cancer OS-RC-2 cells.

Objective To investigate the risk factors affecting the prognosis of preterm infants with septic shock. Methods A retrospective study was conducted to analyze the clinical data of 114 preterm children with septic shock admitted to the Neonatal Intensive Care Unit (NICU) of the PLA Army General Hospital from February 2014 to January 2017. According to the outcomes, these cases were divided into two groups, the cured group and the death group (including those died after ineffective treatment and withdrawal of treatment). Clinical data including the general clinical data, perinatal risk factors, clinical features and prognosis of the two groups of children, as well as the occurrence of related complications were statistically analyzed by t-test, Wilcoxon nonparametric test, Chi-square test or Fisher's exact probability method. Logistic regression was used to analyze the factors influencing the prognosis. Predictive values of the indicators were evaluated using receiver operating characteristic (ROC) curve. Results (1) Among the 114 patients, 87(76.3%) were cured and 27(23.7%) were dead. (2) In the death group, there were more infants complicated with amniotic fluid pollution, anemia and thrombocytopenia (platelet count <100×109/L) and the C-reactive protein (CRP) levels were higher than those in the cured group [29.6% (8/27) vs 8.1% (7/87), χ2=6.618; 22.2% (6/27) vs 5.9% (5/87), χ2=4.665; 59.3% (16/27) vs 23.3% (20/87), χ2=12.546; 36.0 (1.0-80.0) mg/L vs 7.5 (1.0-25.0) mg/L, Z=2.400], while the hemoglobin level was lower [(122.2±43.3) g/L vs (140.5±34.4) g/L, t=2.260] (all P<0.05). (3) The percentages of infants with patent ductus arteriosus, pulmonary hemorrhage and coagulopathy in the death group were higher than those in the cured group [81.5% (22/27) vs 60.9% (53/87), χ2=3.871; 37.0% (10/27) vs 12.6% (11/87), χ2=6.616;48.2% (13/27) vs 20.7% (18/87), χ2=7.847; all P<0.05]. (4) Multivariate logistic regression analysis showed that amniotic fluid contamination, coagulopathy, patent ductus arteriosus and CRP level were risk factors for poor prognosis in neonates (all P<0.05). (5) A total of 77 pathogens were isolated from the 114 infants with 66 in the cured group and 11 in the death group. Pathogens of Gram-positive and Gram-negative bacteria and fungi in the cured and death groups accounted for 37.9% (25/66) vs 3/11, 37.9% (25/66) vs 6/11, and 24.2% (16/66) vs 2/11, respectively. No significant difference in pathogen distribution was observed between the two groups. (6) The area under the ROC curve of CRP was 0.649 (P=0.024). When the cut-off value of CRP was set at 31 mg/L, the sensitivity and specificity for predicting adverse outcomes in preterm infants with septic shock were 0.802 and 0.556, respectively, and the Yoden index was 0.358. The area under the ROC curve of thrombocytopenia was 0.708 (P<0.001). When the platelet level was set at 94×109/L, its sensitivity and specificity were 0.767 and 0.593, respectively, and the Yoden index was 0.360. Conclusions Amniotic fluid contamination, patent ductus arteriosus, coagulopathy and elevated CRP are important risk factors for death in preterm infants with septic shock. Thrombocytopenia and persistently elevated CRP has predictive values for the prognosis of preterm infants with sepsis shock.
