Background:This study explores the relationship between endoplasmic reticulum(ER)stress and diabetes,particularly focusing on the impact of physical exercise on ER stress mechanisms and identifying potential therapeutic drugs and targets for diabetes-related sepsis.The research also incorporates traditional physical therapy perspectives,emphasizing the genomic insights gained from exercise therapy in disease management and prevention.Methods:Gene analysis was conducted on the GSE168796 and GSE94717 datasets to identify ER stress-related genes.Gene interactions and immune cell correlations were mapped using GeneCard and STRING databases.A screening of 2,456 compounds from the TCMSP database was performed to identify potential therapeutic agents,with a focus on their docking potential.Techniques such as luciferase reporter gene assay and RNA interference were used to examine the interactions between microRNA-149-5p and MMP9.Results:The study identified 2,006 differentially expressed genes and 616 miRNAs.Key genes like MMP9,TNF-α,and IL1B were linked to an immunosuppressive state.Licorice glycoside E demonstrated high affinity for MMP9,suggesting its potential effectiveness in treating diabetes.The constructed miRNA network highlighted the regulatory roles of MMP9,IL1B,IFNG,and TNF-α.Experimental evidence confirmed the binding of microRNA-149-5p to MMP9,impacting apoptosis in diabetic cells.Conclusion:The findings highlight the regulatory role of microRNA-149-5p in managing MMP9,a crucial gene in diabetes pathophysiology.Licorice glycoside E emerges as a promising treatment option for diabetes,especially targeting MMP9 affected by ER stress.The study also underscores the significance of physical exercise in modulating ER stress pathways in diabetes management,bridging traditional physical therapy and modern scientific understanding.Our study has limitations.It focuses on the microRNA-149-5p-MMP9 network in sepsis,using cell-based methods without animal or clinical trials.Despite strong in vitro findings,in vivo studies are needed to confirm licorice glycoside E’s therapeutic potential and understand the microRNA-149-5p-MMP9 dynamics in real conditions. 展开更多

AIM: TO examine whether 2'-5'oligoadenylate synthetase (OAS) gene promoter can be specifically activated by hepatitis C virus (HCV)-core protein. METHODS: Human embryo hepatic cell line L02 was transfected with pcDNA3.1-core plasmid and selected by G418. Expression of HCV-core was detected by reverse transcription polymerase chain reaction and Western blotting. The OAS promoter sequence was amplified from the genomic DNA and inserted into pGL3-basic vector. The resultant pGL3-OAS-Luci plasmid was transiently transfected into L02/core cells and luciferase activity was assayed. I^ESULTS: L02/core cell line stably expressing HCV- core protein was established. The pGL3-OAS-Luci construct exhibited significant transcriptional activity in the L02/core cells but not in the L02 cells. CONCLUSION: HCV-core protein activates the OAS gene promoter specifically and effectively. Utilization of OAS gene promoter would be an ideal strategy for developing HCV-specific gene therapy. 展开更多

Aldo-keto reductase 1D1(AKR1D1) deficiency,a rare but life-threatening form of bile acid deficiency,has not been previously described in China.Here,we describe the first two primary 4-3-oxosteroid 5β-reductase deficiency patients in China's Mainland diagnosed by fast atom bombardment-mass spectroscopy of urinary bile acids and confirmed by genetic analysis.A high proportion of atypical 3-oxo-4-bile acids in the urine indicated a deficiency in 4-3-oxosteroid 5β-reductase.All of the coding exons and adjacent intronic sequence of the AKR1D1 gene were sequenced using peripheral lymphocyte genomic DNA of two patients and one of the patient's parents.One patient exhibited compound heterozygous mutations:c.396C>A and c.722A>T,while the other was heterozygous for the mutation c.797G>A.Based on these mutations,a diagnosis of primary 4-3-oxosteroid 5β-reductase deficiency could be confirmed.With ursodeoxycholic acid treatment and fat-soluble vitamin supplements,liver function tests normalized rapidly,and the degree of hepatomegaly was markedly reduced in both patients. 展开更多

Objective The aim of this study was to explore the mechanism behind lncRNA small nucleolar RNA host gene 19(lncRNA SNHG19)/microrNA-299-5P(miR-299-5p)/mitogen-activated protein kinase 6(MAPK6)signaling axis promoting metastasis of non-small cell lung cancer(NSCLC).Methods To analyze the abnormal expression of lncRNAs in NSCLC,50 surgically resected NSCLC and adjacent tissue samples were collected from August 2021 to August 2022.The mRNA expression levels of lncRNA SNHG19,Mir-299-5p,and MAPK6 were detected by qRT-PCR.The functions of lncRNA SNHG19,Mir-299-5p and MAPK6 were investigated by CCK-8,clone formation,EdU,scratch,Transwell western blotting(WB)and in vivo xenograft assay.RNA fluorescence in-situ hybridization(FISH),RNA pull-down,dual luciferase reporter,and RNA co-immunoprecipitation assays were used to explore the mechanism of action between lncRNA SNHG19,miR-299-5p,and MAPK6.Results High expression of lncRNA SNHG19 was correlated with poor prognosis,tumor size,lymph node metastasis,and TNM stage in NSCLC patients(P<0.05).Cell function experiments showed that lncRNA SNHG19 could improve the proliferation,clone formation,migration,and invasion ability of A549 cells both in vitro and in vivo(all P<0.05)and increased the relative expression levels of vimentin and MAPK6(P<0.05).The relative expression level of E-cadherin was decreased(P<0.05).lncRNA SNHG19 can interact with Mir-299-5p and regulate the expression level of MAPK6.Conclusion lncRNA SNHG19 is upregulated in NSCLC tissues and cells,and its high expression is associated with tumor progression and poor survival.Moreover,it can act as a molecular sponge for Mir-299-5p to regulate MAPK6 expression and promote the proliferation and metastasis of A549 cells. 展开更多

Objective To observe the regulation of Fengxiaofang on the expression of gene Gob-5 in ovalbumin-challenged asthmatic mice.Methods The murine model of allergic asthma established by ovalbumin was used.The model mice were treated experimentally with Fengxiaofang and Dexamethasone as a positive control.The quantitive expression of gene Gob-5 in lung of mice was detected by real-time quantitative PCR.Results The expression of gene Gob-5 in lung of mice was down-regulated by Fengxiaofang.In the experiment,there were no significant differences between the one-fold or ten-fold dosage groups and the normal control group.Gene Gob-5 expression in five-fold dosage was significantly lower than that in the normal control group.Conclusion Fengxiaofang has the effect of lowering the expression of gene Gob-5 which maybe related to the potency on asthmatic disease. 展开更多

The genes for 5-1ipoxygenase activating protein (ALOX5AP) and phosphodiesterase 4D (PDE4D) have been demonstrated as susceptibility genes for lacunar in the Icelandic and Pakistani populations, but little is known about the role of these genes in Chinese populations. The present study utilized polymerase chain reaction and ligase detection reaction to detect single nucleotide polymorphisms (SNPs) in 280 consecutive stroke patients and 258 unrelated population-based controls from Nanjing, Jiangsu Province, China. The allele frequency, genotypes, and haplotypes of the two SNPs (rs456009 and rs966221) in PDE4D were similar between the two groups. However, A allele frequency of rs4073259 (A/G) and rs4769055 (A/C) in the ALOX5AP gene exhibited differences in two groups, and especially the haplotype of the SNP was significantly different between the two groups. Results suggested that the ALOX5AP gene might be involved in lacunar infarct, while PDE4D gene was not a risk factor for lacunar infarct in individuals from Jiangsu Province, China. 展开更多
