Identification of FKBP10 prognostic value in lung adenocarcinoma patients with surgical resection of brain metastases: A retrospective single-institution cohort study

Abstract Objective To explore the expression levels and clinical value of FKBP10 in lung adenocarcinoma brain metastases. Design A retrospective single-institution cohort study. Patients The perioperative records of 71 patients with lung adenocarcinoma brain metastases who underwent surgical resection at the authors' institution between November 2012 and June 2019 were retrospectively analyzed. Methods The authors evaluated FKBP10 expression levels using immunohistochemistry in tissue arrays of these patients. Kaplan-Meier survival curves were constructed, and a Cox proportional hazards regression model was used to identify independent prognostic biomarkers. A public database was used to detect FKBP10 expression and its clinical value in primary lung adenocarcinoma. Results The authors found that the FKBP10 protein was selectively expressed in lung adenocarcinoma brain metastases. Survival analysis showed that FKBP10 expression (p = 0.02, HR = 2.472, 95% CI [1.156, 5.289]), target therapy (p < 0.01, HR = 0.186, 95% CI [0.073, 0.477]), and radiotherapy (p = 0.006, HR = 0.330, 95% CI [0.149, 0.731]) were independent prognostic factors for survival in lung adenocarcinoma patients with brain metastases. The authors also detected FKBP10 expression in primary lung adenocarcinoma using a public database, found that FKBP10 is also selectively expressed in primary lung adenocarcinoma, and affects the overall survival and disease-free survival of patients. Limitations The number of enrolled patients was relatively small and patients' treatment options varied. Conclusions A combination of surgical resection, adjuvant radiotherapy, and precise target therapy may benefit the survival of selected patients with lung adenocarcinoma brain metastases. FKBP10 is a novel biomarker for lung adenocarcinoma brain metastases, which is closely associated with survival time and may serve as a potential therapeutic target.

Cell-penetrating Effects and Repair of Cell Oxidative Damage of TAT-metallothionein Fusion Proteins / 中国生物化学与分子生物学报

The human Immunodeficiency Virus Transactivator (TAT) protein transduction peptide is a trans-transcription activator encoded by HIV-1. It is rich in basic amino acids, and capable of efficiently mediating the passage of exogenous macromolecules through a variety of membrane structures, such as the cytoplasmic membrane and the blood-brain barrier. Metallothionein (MT) is a protein with low molecular weights and rich cysteine contents. It plays important roles in maintaining the dynamic balance of metal contents in the body, in the detoxification of heavy metals and in defense against oxidative stress. Based on the full-length MT cDNA previously cloned from Sinopotamon henanense, we aim to prepare a TAT-mediated recombinant fusion protein that can cross the membrane and enter the cell by means of genetic engineering. The hydroxyl radical scavenging rate and total antioxidant capacity of TAT-MT were measured in vitro. An immunofluorescence technique was used to detect the transmembrane activity. An MTT assay was used to study the repair effect of H

Smad1/5 signal transduction regulates the ameloblastic differentiation of induced pluripotent stem cells

Abstract Induced pluripotent stem (iPS) cells could be induced into ameloblast-like cells by ameloblasts serum-free conditioned medium (ASF-CM), and bone morphogenetic proteins (BMPs) might be essential during the regulation of this process. The present study investigates the signal transduction that regulates the ameloblastic differentiation of iPS cells induced by ASF-CM. Mouse iPS cells were characterized and then cultured for 14 days in epithelial cell medium (control) or ASF-CM. Bone morphogenetic protein receptor II (BMPR-II) siRNA, inhibitor of Smad1/5 phosphorylation activated by activin receptor-like kinase (ALK) receptors, and inhibitors of mitogen-activated protein kinases (MAPKs) phosphorylation were used to treat the iPS cells in combination with ASF-CM. Real-time PCR, western blotting, and immunofluorescent staining were used to evaluate the expressions of ameloblast markers ameloblastin, enamelin, and cytokeratin-14. BMPR-II gene and protein levels increased markedly in ASF-CM-treated iPS cells compared with the controls, while the mRNA levels of Bmpr-Ia and Bmpr-Ib were similar between the ASF-CM and control groups. ASF-CM stimulation significantly increased the gene and protein expression of ameloblastin, enamelin and cytokeratin-14, and phosphorylated SMAD1/5, p38 MAPK, and ERK1/2 MAPK compared with the controls. Knockdown of BMPR-II and inhibition of Smad1/5 phosphorylation both could significantly reverse the increased expression of ameloblastin, enamelin, and cytokeratin-14 induced by ASF-CM, while neither inhibition of p38 nor ERK1/2 phosphorylation had significant reversing effects. We conclude that smad1/5 signaling transduction, activated by ALK receptors, regulates the ameloblastic differentiation of iPS cells induced by ameloblast-conditioned medium.

lncRNA MEG3 inhibits the growth of hepatocellular carcinoma cells by sponging miR-9-5p to upregulate SOX11

The long non-coding RNA (lncRNA) maternally expressed gene 3 (MEG3), a tumor suppressor, is critical for the carcinogenesis and progression of different cancers, including hepatocellular carcinoma (HCC). To date, the roles of lncRNA MEG3 in HCC are not well illustrated. Therefore, this study used western blot and qRT-PCR to evaluate the expression of MEG3, miR-9-5p, and Sex determining Region Y-related HMG-box 11 (SOX11) in HCC tissues and cell lines. RNA pull-down and luciferase reporter assay were used to evaluate these molecular interactions. 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide and flow cytometry detected the viability and apoptosis of HCC cells, respectively. The results showed that MEG3 and SOX11 were poorly expressed but miR-9-5p was highly expressed in HCC. The expression levels of these molecules suggested a negative correlation between MEG3 and miR-9-5p and a positive correlation with SOX11, confirmed by Pearson's correlation analysis and biology experiments. Furthermore, MEG3 could combine with miR-9-5p, and SOX11 was a direct target of miR-9-5p. Moreover, MEG3 over-expression promoted cell apoptosis and growth inhibition in HCC cells through sponging miR-9-5p to up-regulate SOX11. Therefore, the interactions among MEG3, miR-9-5p, and SOX11 might offer a novel insight for understanding HCC pathogeny and provide potential diagnostic markers and therapeutic targets for HCC.

Correlation between myocardial velocity measured using tissue doppler imaging in the left ventricular lead-implanted segment and response to cardiac resynchronization therapy

OBJECTIVES: This study investigated whether tissue Doppler imaging parameters, especially the peak systolic velocity of the left ventricular lead-implanted segment (Ss), affect cardiac resynchronization therapy response. METHODS: In this case-control study, 110 enrolled patients were divided into cases (responder group, n=65) and controls (nonresponder group, n=45) based on whether their left ventricular end-systolic volume was reduced by ≥15% at 6 months after surgery. Preoperative clinical and echocardiographic data were collected. Multivariate logistic regression models were used to analyze the factors affecting the response to cardiac resynchronization therapy, and receiver operating characteristic curves were plotted to evaluate their diagnostic values. RESULTS: The proportion of patients with left bundle branch block in the case group was higher than that in the control group. The control group showed a higher left atrial volume index, E/A ratio and E/Em ratio but lower Ss than that of the case group. A multivariate regression analysis showed that left bundle branch block, Ss, and an E/Em ratio>14 were independent risk factors affecting the response to cardiac resynchronization therapy. Ss=4.1 cm/s was the best diagnostic threshold according to the receiver operating characteristic curve. CONCLUSIONS: Ss is an important factor affecting the response to cardiac resynchronization therapy. Patients with heart failure associated with Ss<4.1 cm/s have a higher risk of nonresponse.

Genetic Diversity of Ambrosia trifida L. as Revealed by AFLP Markers

Aims: Invasion of alien species has become a global problem. Many invaders appear to thrive even with low levels of sequence-based genetic variation, and genetic patterns might congruent with the spatial arrangement of populations. Study Design: The genetic diversity of giant ragweed was investigated using amplified fragment length polymorphism (AFLP). There were 5 populations(100 samples), and the distance between the two populations was more than 20 kilometers along with the mainstream of Liaohe. Place and Duration of Study: Samples were collected from Liaohe Basin. Experiments were done in the College of Biological Science and Technology, between February 2016 and March 2017. Methodology: The distance between the two populations was more than 20 kilometers. We sampled five populations of Ambrosia trifida L. along Liaohe river in Liaoning province (north-east of China). Leaves for AFLP experiment were stored in discoloration silica gel. Genomic DNA was extracted following the CTAB protocol. Results: The genetic distances varied with the geographic distances. However, with the influence of many different situations, and many modes of transmission, the discrepancy of genetic distance was reflected. There was low genetic diversity during earlier period of invasion diversity. After a period of invasion, genetic diversity gradually increased. Panshanzha number of polymorphic bands and percentage of polymorphic bands was 98 and 64.47% respectively. Manduhu was 93 and 61.16%, Juliuhe was 100 and 65.79%, Shifosi was 98 and 64.47%, Shuanganqiao was 127 and 83.55%. Shuanganqiao possessed the highest polymorphism. Conclusion: The source of genetic variation of giant ragweed in Liaohe was gene flow of population. Shuanganqiao might be the spread center.

Short-term efficacy and safety of low-intensity extracorporeal shock wave therapy in erectile dysfunction: a systematic review and meta-analysis

ABSTRACT Aim: The role of low-intensity extracorporeal shock wave therapy (LI-ESWT) in erectile dysfunction (ED) is not clearly determined. The purpose of this study is to investigate the short-term efficacy and safety of LI-ESWT for ED patients. Materials and Methods: Relevant studies were searched in Medline, Embase, Cochrane Library, China National Knowledge Infrastructure (CNKI), WANFANG and VIP databases. Effective rate in terms of International Index of Erectile Function-Erectile Function Domain (IIEF-EF) and Erectile Hardness Score (EHS) at about 1XSmonth after LI-ESWT was extracted from eligible studies for meta-analysis to calculate risk ratio (RR) of effective treatment in ED patients treated by LI-ESWT compared to those receiving sham-treatment. Results: Overall fifteen studies were included in the review, of which four randomized controlled trials (RCTs) were for meta-analysis. Effective treatment was 8.31 [95°/o confidence interval (CI): 3.88-17.78] times more effective in the LI-ESWT group (n=176) than in the sham-treatment group (n= 101) at about 1 month after the intervention in terms of EHS, while it was 2.50 (95% CI: 0.74-8.45) times more in the treatment group (n= 121) than in the control group (n=89) in terms of IIEF-EF. Nine-week protocol with energy density of 0.09mJ/mm2 and 1500 pluses seemed to have better therapeutic effect than five-week protocol. No significant adverse event was reported. Conclusion: LI-ESWT, as a noninvasive treatment, has potential short-term therapeutic effect on patients with organic ED irrespective of sensitivity to PDE5is. Owing to the limited number and quality of the studies, more large-scale, well-designed and longterm follow-up time studies are needed to confirm our analysis.

ER Stress-Mediated Cell Damage Contributes to the Release of EDA+ Fibronectin from Hepatocytes in Nonalcoholic Fatty Liver Disease / 华中科技大学学报（医学）（英德文版）

Fibronectin containing extra domain A (EDA+ FN),a functional glycoprotein participating in several cellular processes,correlates with chronic liver disease.Herein,we aim to investigate the expression and secretion of EDA+ FN from hepatocytes in nonalcoholic fatty liver disease (NAFLD) and the underlying mechanisms.Circulating levels of EDA+ FN were determined by ELISA in clinical samples.Western blotting and flow cytometry were performed on L02 and HepG2 cell lines to analyze whether the levels of EDA+ FN were associated with endoplasmic reticulum (ER) stress-related cell death.Circulating levels of EDA+ FN in NAFLD patients were significantly higher than those in control subjects,and positively related with severity of ultrasonographic steatosis score.In cultured hepatocytes,palmitate up-regulated the expression of EDA+ FN in a dose-dependent manner.Conversely,when the cells were pretreated with 4-phenylbutyrate,a specific inhibitor of ER stress,up-regulation of EDA+ FN could be abrogated.Moreover,silencing CHOP by shRNA enhanced the release of EDA+ FN from hepatocytes following palmitate treatment,which was involved in ER stress-related cell damage.These findings suggest that the up-regulated level of EDA+ FN is associated with liver damage in NAFLD,and ER stress-mediated cell damage contributes to the release of EDA+ FN from hepatocytes.

Haploinsuffieiency of the runt-related transcription factor 2 (Runx2) gene is widely known to be responsible for cleidocranial dysplasia (CCD).To date,more than 190 mutations in Runx2 gene have been reported to be related to CCD.In this study,a novel mutation of Runx2 gene was observed in a female with CCD.Genomic DNA was extracted from peripheral venous blood of the proband and eleven members of her family.Genetic testing on these twelve people identified a novel missense mutation (c.895T＞C,Y299H) in exon 5 of the RUNX2 gene in the proband.This mutation results in an amino acid change at codon 895 (P.Tyr 299 His.) from a tryptophan codon (TAT) to a histidine codon (CAT).Our finding may further extend the known mutation spectrum of the RUNX2 gene,and facilitate prenatal genetic diagnosis of CCD in the future.

Mild Encephalopathy/Encephalitis with a Reversible Splenial Lesion (MERS): A Report of Five Neonatal Cases / 华中科技大学学报（医学）（英德文版）

Mild encephalopathy/encephalitis with a reversible spleniat (MERS) lesion is a clinic-radiological entity.The clinical features of MERS in neonates are still not systemically reported.This paper presents five cases of MERS,and the up-to-date reviews of previously reported cases were collected and analyzed in the literature.Here we describe five cases clinically diagnosed with MERS.All of them were neonates and the average age was about 4 days.They were admitted for the common neurological symptoms such as hyperspasmia,poor reactivity and delirium.Auxiliary examinations during hospitalization also exhibited features in common.In this report,we reached following conclusions.Firstly,magnetic resonance imaging revealed solitary or comprehensive lesions in the splenium of corpus callosum,some of them extending to almost the whole corpus callosum.The lesions showed low intensity signal on Tl-weighted images,homogeneously hyperintense signal on T2-weighted images,fluid-attenuated inversion recovery and diffusion-weighted images,and exhibited an obvious reduced diffusion on apparent diffusion coefficient map.Moreover,the lesions in the magnetic resonance imaging disappeared very quickly even prior to the clinical recovery.Secondly,all the cases depicted here suffered electrolyte disturbances especially hyponatremia which could be easily corrected.Lastly,all of the cases recovered quickly over one week to one month and majority of them exhibited signs of infections and normal electroencephalography.

Regulatory effect of miRNA 320a on expression of aquaporin 4 in brain tissue of epileptic rats

OBJECTIVE@#To study the expression of miRNA 320a in the brain tissue of epileptic rats and analyze its effect on the expression of aquaporin 4 (AQP4).@*METHODS@#All rats were performed with the intraperitoneal injection of lithium chloride (3 mmol/kg) and then the intraperitoneal injection of pilocarpine (30 mg/kg) 24 h later (injected twice) to prepare the epileptic model of Wistar rats. Rats in the control group were injected with the equal volume of normal saline. According to the Racine scale, rats with over stage 3 of epilepsy were chosen and the brain tissue was separated quickly and then stored at -80 °C. The immunohistochemistry was used to detect the expression of aquaporin in the brain tissue of epileptic model and the Real-time PCR was employed to determine the difference in the expression of miRNA 320a and AQP4 in the brain tissue of rats between the epileptic model group and control group. Five 5-day neonatal Wistar rats were chosen to collect the cerebral cortex and their primary astrocytes were separated and cultured. They were transfected with miRNA mimic and imitated to the endogenous miRNA 320a to up-regulate the expression of miRNA 320a.@*RESULTS@#In the model group, the expression of AQP4 was significantly higher than the control group (P < 0.01). However, the expression of miRNA 320a in the model group was lower than control group (P < 0.05), which was negatively correlated to AQP4. In the primary astrocytes, the transfection of miRNA 320a mimic could significantly reduce the expression of AQP4, while its inhibitor could up-regulate the expression of AQP4, which indicated that miRNA 320a could reduce the expression of AQP4.@*CONCLUSIONS@#In the primary astrocytes of rats, the miRNA 320a could inhibit the expression of AQP4 and after adding the inhibitor of miRNA 320a, the expression of AQP4 was up-regulated.
