Single nucleotide polymorphisms (SNPs) of Xeroderma pigmentosum group D (XPD) are associated with various types of cancer. However, previous studies of correlations between SNPs in this gene and esophageal squamous cell carcinoma (ESCC) have generated conflicting results. In the present study, we investigated the potential relationship between SNPs in two key regions of XPD, codons 312 and 751 and ESCC in a Chinese population. Polymerase chain reaction-restriction fragment length polymorphism was used to analyze genotypes at codons 312 and 751 of XPD in 400 ESCC patients (case group) and 400 healthy individuals (control group). Logistic regression was used to analyze the relationship between genotypes and ESCC. No statistically significant difference was observed for the genotype or allele frequencies of codon 312 between case and control groups (P>0.05). However, a statistically significant difference was observed in the genotype and allele frequencies of codon 751 between the case and control groups (P<0.05). Specifically, compared with the AA genotype at codon 751, a significant increase in risk of ESCC was detected for individuals with the CC genotype (OR=1.600; 95% CI, 1.137-2.253; P=0.007). Therefore, XPD polymorphism at codon 312 is not correlated with ESCC, while polymorphism at codon 751 is associated with ESCC and the CC genotype may confer increased susceptibility to the disease.

Previous studies on the associations of the NFKB1 -94 insertion/deletion polymorphism with cancer risk have produced conflicting results. The purpose of this meta-analysis is to define the effect of the NFKB1 -94 insertion/deletion polymorphism on cancer risk. A search of the literature by PubMed was performed to identify studies based on the predetermined inclusion criteria. Twenty-three studies consisting of 6,494 cases and 9,884 controls were identified and analyzed. Overall, significant association was observed between the polymorphism and cancer risk under all genetic models. Subgroup analysis according to ethnicity and cancer type also detected significant association. The NFKB1 -94 insertion/deletion polymorphism was associated with cancer risk in Asian population (dominant model: OR=1.52, 95 % CI=1.17-1.98; recessive model: OR=1.50, 95 % CI=1.26-1.79; II vs. DD: OR=1.90, 95 % CI=1.37-2.65; ID vs. DD: OR=1.32, 95 % CI=1.05-1.66; I vs. D: OR=1.37, 95 % CI=1.17-1.60), but not in Caucasian population. In addition, significant associations in OC, HCC, and OSCC were observed, but significant associations were not found in BC and LC. The current meta-analysis suggested that NFKB1 -94 insertion/deletion polymorphism may influence cancer risk in Asian population. © 2014 International Society of Oncology and BioMarkers (ISOBM).

Objectives-This study was conducted to evaluate the value of sonographic B-lines (previously called "comet tail artifacts") in assessment of pulmonary hypertension in patients with interstitial lung diseases. Methods-One hundred thirty-four patients with clinically diagnosed interstitial lung diseases complicated by pulmonary hypertension underwent transthoracic lung sonography and Doppler echocardiography for assessment of the presence of B-lines, the distance between them, and the pulmonary artery (PA) systolic pressure. A correlation analysis and a receiver operating characteristic curve analysis were performed. Results-All patients had diffuse bilateral B-lines. The maximum number of B-lines seen in any positive zone (not a summation) was significantly correlated with the severity of PA systolic pressure (r = 0.812; P< .0001), and a linear regression equation could be demonstrated: that is, y = 6.06 x + 17.57, where x and y represent the number of Blines and PA systolic pressure, respectively. A cutoff of more than 4 B-lines seen in any positive zone had 89.5% sensitivity, 85.0% specificity, and 87.2% accuracy in predicting elevated PA pressure (>30 mm Hg). Conclusions-The number of B-lines is useful in assessment of pulmonary hypertension, especially when tricuspid regurgitation and pulmonary valve regurgitation do not exist or cannot be satisfactorily measured by Doppler echocardiography. © 2015 by the American Institute of Ultrasound in Medicine.

Objectives-The clinical presentation of myocarditis often mimics acute coronary syndrome. Coronary sinus flow has been used for detection of the presence of myocardial ischemia. Whether myocarditis is associated with changes in coronary sinus flow remains unknown. The aim of this study was to assess coronary sinus flow at the onset and follow-up of myocarditis mimicking acute coronary syndrome using transthoracic Doppler echocardiography (TTE). Methods-Sixty-four patients with clinically diagnosed viral myocarditis mimicking acute coronary syndrome underwent TTE on days 3, 7, 30, 90, 180, and 360 after onset. Coronary sinus flow was compared among different points in time. Results-Compared to healthy participants, all patients with myocarditis had a larger cardiac size, reduced cardiac function, and electrocardiographic and myocardial enzyme abnormalities on days 3 and 7 days (P< .01; P< .05). They later had gradual restoration to normal levels. On days 3 and 7, the coronary sinus flow in patients with myocarditis was extremely lower than that in healthy participants (about one-tenth), although coronary angiography revealed unobstructed arteries. On days 30, 90, 180, and 360, the coronary sinus flow had been increasing; however, it was still far less than that in healthy participants (P < .01). Conclusions-Coronary sinus flow depicted by TTE is reduced but recovers with time in viral myocarditis mimicking acute coronary syndrome, which is a useful indicator in the follow-up of this type of myocarditis. © 2016 by the American Institute of Ultrasound in Medicine.

Gliomas are the most common type of brain tumor in the central nervous system of adults, and are highly aggressive, resistant to treatment, and prone to recurrence. Brain tumor stem cells (BTSCs) are implicated in tumor initiation and recurrence. Cluster of differentiation (CD)133 is currently the most widely used BTSC marker; however, its role in glioma development and progression is largely unknown. In this study, we evaluated CD133 expression in pairs of primary and recurrent human glioma specimens from 24 patients. We found that recurrent gliomas have aberrantly upregulated CD133 levels. To clarify the mechanism underlying this observation, we assessed CD133 promoter (P)2 methylation status by bisulfite sequencing and found that P2 hypomethylation was associated with the increase in CD133 expression and glioma recurrence. These results suggest that CD133 overexpression in BTSCs due to P2 hypomethylation underlies glioma recurrence, which may provide insight into the mechanism of glioma recurrence and provide a basis for novel therapies for glioma treatment.

NF-B subunits play important roles in carcinogenesis of a variety of human malignancies and response to cancer therapy; however, the contribution of an individual subunit has not been thoroughly defined. Constitutive activation of the canonical NF-B subunit is a critical event in prostate carcinogenesis. Recent findings point out that RelB, which contributes to the non-canonical NF-B activity, functions importantly in the prostate cancer progression. Here, we investigated systemically the functional roles of RelB in prostate cancer and examine its significance as a therapeutic target. Targeting RelB using short hairpin RNA approach in androgen-independent DU145 prostate cancer cells interfered with various biological behaviors of cells. We observed that RelB knockdown inhibited prostate cancer cell growth, migration, and invasion, and enhanced proteasome inhibitor sensitivity. The altered expression of anti-apoptotic gene Bcl-2 played critical roles in regulating both spontaneous and radiation-induced apoptosis in the presence of RelB knockdown. For the first time, we showed that RelB knockdown significantly attenuated the migration and invasion of DU145 prostate cancer cells, due to the reduction of integrin-1. Collectively, we provided evidence that RelB functioned as an oncogene in prostate cancer. Developing a RelB-targeted therapeutic intervention, is valuable in treating advanced, metastatic prostate cancer.

TNF receptor associated factor 3 (TRAF3), a member of the TRAF family of intracellular signaling proteins, can directly influence the phosphorylation status and activation of c-Jun N-terminal kinase, participating in CD40-induced apoptosis in carcinoma. However, its expression profile and function are still unclear in spinal cord injury (SCI). In this study, we performed an acute spinal cord contusion injury model in adult rats and detected the dynamic change patterns of TRAF3 expression in spinal cord. Western blot and immunohistochemistry revealed a striking upregulation of TRAF3 after SCI. Double immunofluorescence staining prompted that TRAF3 immunoreactivity was found in neurons rather than astrocytes. Moreover, co-localization of TRAF3/active caspase-3 was detected in neuronal nuclei. To further investigate the function of TRAF3, a neuronal cell line PC12 was employed to establish an apoptosis model in vitro. We analyzed the association of TRAF3 with active caspase-3 on PC12 cells by western blot and immunofluorescent labeling, which was parallel with the data in vivo. Additionally, knocking TRAF3 down with siRNA demonstrated the probable pro-apoptotic role of TRAF3 in the process of neuronal apoptosis. To summarize, we firstly uncover the temporal and spatial expression changes of TRAF3 in SCI. Our data suggest that TRAF3 might be implicated in central nervous system pathophysiology after SCI. © 2014 Springer Science+Business Media.

Increasing evidence suggests that dysregulation of microRNAs is correlated with malignant transformation and tumor development. miR-100, a potential tumor suppressor, is downregulated by many human cancers. However, the expression and functions of miR-100 in hepatocellular carcinoma (HCC) are still unclear. The aim of this study was to detect the expression of miR-100 in HCC tissues and investigate its clinicopathological and prognostic significance. Also, the effects of miR-100 on growth and apoptosis of HCC cells and its potential molecular mechanisms were analyzed. Results showed that the expression level of miR-100 in HCC tissues was significantly lower than that in matched non-cancerous liver tissues. Also, low-miR-100 expression was observed to be significantly correlated with higher tumor grade, higher incidence of lymph node metastasis, advanced TNM stage and higher incidence of tumor recurrence in HCC patients. Multivariate survival analyses suggested that low-miR-100 expression was an independent prognostic factor for HCC patients (HR = 1.66, 95 % CI 1.32-2.82, P = 0.019). In addition, we found that upregulation of miR-100 could inhibit growth and increase apoptosis of HCC cells by downregulating polo-like kinase 1 (plk1). In HCC tissues, miR-100 expression was inversely correlated with the expression of plk1 protein (r = -0.418; P = 0.029). Therefore, downregulation of miR-100 was correlated with progressive pathological feature and poor prognosis in HCC patients, and miR-100 could function as a tumor suppressor by targeting plk1. miR-100 may serve as a prognostic marker and molecular therapeutic target in HCC. © 2013 Springer Science+Business Media New York.

Dobutamine has been widely used for the treatment of heart failure and cardiogenic shock since the 1970s. Osteosarcoma is the most commonly observed malignant bone tumor in children. Currently, there are no effective drugs for the treatment of osteosarcoma. In the present study, the potential anticancer activity of dobutamine on human osteosarcoma cells was examined. Human osteosarcoma MG-63 cells were treated with dobutamine at various concentrations and for various incubation times. The inhibition of cell growth by dobutamine was determined by 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide assay. Flow cytometry was utilized to evaluate the effect of dobutamine on cell apoptosis and the cell cycle. Furthermore, the expression levels of caspase-3 and caspase-9 were assessed by western blot analysis. The influence of dobutamine on cancer cell migration and invasion was additionally evaluated using wound-healing assay and the Boyden Chamber migration method. Dobutamine significantly inhibited the growth of MG-63 cells at a concentration of 10 M or higher when incubated for 12 h or longer (P=0.023). Dobutamine augmented cell apoptosis and arrested the cell cycle in the G2/M phase. Western blot analysis revealed that dobutamine induces expression of caspase-3 and caspase-9. In addition, the invasiveness and migration of MG-63 cells was inhibited by dobutamine in a concentration-dependent manner. The results of the present study may lead to novel applications for dobutamine in the treatment of osteosarcoma.
