Hsa_circRNA_0017620 regulated cell progression of non‐small‐cell lung cancer via miR‐520a‐5p/KRT5 axis

BackgroundCircRNA is a very important functional RNA that plays an important role in the development and metabolism of cancer. However, the study of circRNA in NSCLC has not been fully elucidated.MethodsThe expression of hsa_circ_0017620, SFMBT2, miR‐520a‐5p, and KRT5 was determined using qRT‐PCR. KRT5, Twist1, E‐cadherin, and Ki67 protein expression were measured with western blot. The positive expression rates of Ki67 and Vimentin were determined by immunohistochemistry assay. 5‐Ethynyl‐2’‐deoxyuridine (EdU), colony formation, and MTT assays were used to assess cell proliferation. Transwell migration and invasion assay were applied to determine cell migration and invasion. Dual‐luciferase reporter and RNA immunoprecipitation assays were used to verify the relationship among hsa_circ_0017620, miR‐520a‐5p, and KRT5. The animal experiment was used to ensure the effects of hsa_circ_0017620 on tumor growth in vivo.ResultsHsa_circ_0017620 was upregulated in NSCLC cells and tissues. MiR‐520a‐5p had been verified to be a target miRNA of hsa_circ_0017620 and KRT5 had been verified to be a target mRNA of miR‐520a‐5p in NSCLC cells. Knockdown of hsa_circ_0017620 inhibited cell proliferation, migration, and invasion in NSCLC cells, which was reversed by downregulating miR‐520a‐5p or upregulating KRT5 in NSCLC. Overexpression of hsa_circ_0017620 had opposite effects in NSCLC. Moreover, hsa_circ_0017620 silencing inhibited tumor growth in vivo of NSCLC.ConclusionIn this study, we found that hsa_circ_0017620 played an important role in NSCLC progression. Hsa_circ_0017620 regulated cell proliferation, invasion, and migration through targeting miR‐520a‐5p/KRT5 axis in NSCLC, providing a potential new target for the treatment and diagnosis of NSCLC.

Establishment of transgenic mice carrying the gene of human nuclear receptor NR5A2 （hB1F）

AIM: Human hepatitis B virus enhancer II B1 binding factor (hB1F) was cloned and characterized as a novel member of the Ftz-F1 (NR5A) nuclear receptor subfamily. Although progresses have recently been made, its biological function remains largely unidentified. The aim of this study was to establish an hB1F transgenic mouse model to promote the functional study of hB1F. METHODS: Transgene fragments were microinjected into fertilized eggs of mice. The manipulated embryos were transferred into the oviducts of pseudopregnant female mice. The offsprings were identified by PCR and Southern blot analysis. Transgene expression was analyzed with RT-PCR and Western blot analysis. Transgenic founder mice were used to establish transgenic mouse lineages. The F1 and F2 mice were identified by PCR analysis. RESULTS: Seven mice were identified as carrying copies of transgene. RT-PCR and Western blotting results showed that the transgene was expressed in heart, liver, lung, kidney and stomach in one of the transgenic mouse lineages. Genetic analysis of the transgenic mice demonstrated that the transgene was integrated into the chromosome at a single site, and was transmitted stably. CONCLUSION: In this study we established an hB1F transgenic mouse model, which will facilitate the investigation of the biological function of hB1F in vivo.

目的探讨TIM I风险积分对介入治疗后急性冠脉综合征（ACS）患者短期预后的预测作用及比较不同积分组血浆脑钠尿肽（BNP）水平。方法连续入选2004年11月至2005年4月因ST段抬高的心肌梗死（STEM I）在我院行经皮冠状动脉介入（PC I）治疗者75例,因不稳定型心绞痛（UAP）/非ST段抬高的心肌梗死（NSTEM I）在我院行PC I治疗者47例,入院时对入选患者进行心肌梗死溶栓试验（TIM I）风险积分。采用荧光免疫方法测定血浆BNP水平。结果在STEM I患者组,根据TIM I风险积分分为04分,59分,1014分3组。随着TIM I风险积分升高,各组病死率呈明显递增趋势。在多变量的Logistic回归分析中,TIM I风险积分能够独立预测住院期间、1个月和3个月病死率及住院期间、1个月主要心血管不良事件（MACE）发生率（均P<0.01）。不同的TIM I风险积分各组间血浆BNP水平有显著性差异（P<0.01）。在多元回归分析中,TIM I风险积分分组不受年龄、性别、家族史、吸烟、高胆固醇血症、高血压、糖尿病等因素的影响,而与血浆BNP水平呈独立正相关（r=0.52,P<0.01）。在UAP/NSTEM I患者组,根据TIM I风险积分分为02分,35分,57分3组。随着TIM I风险积分升高,各组病死率呈明显递增趋势。在多变量的Logistic回归分析中,TIM I风险积分能够独立预测3个月病死率及1个月和3个月MACE发生率（均P<0.01）。各组间血浆BNP水平有显著性差异（P<0.01）。在多元回归分析中,TIM I风险积分分组经年龄、性别、高胆固醇血症因素校正后与血浆BNP水平呈正相关（r=0.41,P<0.01）。结论TIM I风险积分能够较好地对ACS患者进行危险分层,预测短期病死率和MACE发生率。ACS患者按TIM I风险积分递增分组与血浆BNP水平呈正相关。TIM I风险积分越高组血浆BNP水平越高。

Sonosensitizer nanoplatform-mediated sonodynamic therapy induced immunogenic cell death and tumor immune microenvironment variation

Epithelial ovarian cancer (EOC) is one of the most lethal gynecologic malignancies, and effective treatments are still lacking due to drug tolerance and tumor recurrence. In this study, we aimed to investigate the effects of sonodynamic therapy (SDT) on ovarian cancer and its potential mechanism. Folate receptor-targeted and ultrasound-responsive nanoparticles (NPs) were constructed using PLGA-PEG-FA (PLGA: poly (lactic-co-glycolic) acid, polyethylene glycol (PEG), FA: folate), the reactive oxygen species (ROS)-generating sonosensitizer IR780 and the oxygen-carrying material perfluorohexane (PFH), termed IRO@FA NPs. The antitumor effect of NPs triggered by ultrasound (US) was measured by an apoptosis assay in a C57/BL6 mouse model. Immunochemistry and flow cytometry were used to detect the proportion of CD3⁺ T, CD4⁺ T, CD8⁺ T cells and activated dendritic cells (DCs) in spleens and tumor tissues to assess variation in the immune response. Moreover, endoplasmic reticulum (ER) stress and immunogenic cell death (ICD) markers (high mobility group protein box-1, ATP and calreticulin) were detected to identify potential mechanisms. The results showed that IRO@FA NP-mediated SDT promoted ID8 cell apoptosis both in vitro and in vivo. The densities of CD3⁺ and CD8⁺ T lymphocytes and inflammatory markers were upregulated in tumor tissues. IRO@FA NP-mediated SDT prompted DC maturation and T lymphocyte infiltration by inducing ID8 cell ICD.
