MicroRNAs play important roles in regulating tumour development, progression and metastasis. Here we show that one of the miR-200 family members, miR-141, is under-expressed in several prostate cancer (PCa) stem/progenitor cell populations in both xenograft and primary patient tumours. Enforced expression of miR-141 in CD44+ and bulk PCa cells inhibits cancer stem cell properties including holo...

BACKGROUND Among HIV-1-infected individuals, cytomegalovirus (CMV) reactivation and disease occur in the setting of advanced immunosuppression. The value of a standardized assessment of CMV-specific T-cell mediated immunity by the CMV QuantiFERON assay (CMV-QFT) has not yet been thoroughly investigated in HIV-1-infected subjects. METHODS Prospective, longitudinal study in 153 HIV-1-infected s...

BACKGROUND The clinical significance of miR-141-3p in hepatocellular carcinoma has not been verified. Therefore, we conducted this study to examine miR-141-3p expression and its clinical significance in hepatocellular carcinoma and to investigate the functions of its potential targets. METHODS The Cancer Genome Atlas database and the Gene Expression Omnibus database were used to explore the a...

OBJECTIVE This study aimed to investigate the expression of miR-200c and miR-141 in glioma tissues and cell lines and then to study their regulative effect on ZEB1 expression and on glioma cell growth and migration. MATERIALS AND METHODS QRT-PCR analysis was performed to detect miR-200c and miR-141 expression in 10 paired glioma tissues and adjacent normal tissues from patients with glioblast...

our synthetic ape C-il (46-58) gave a negative response when tested with purified native apolipoprotein C-fl. Double iminunodiffusion (Ouchterlony technique) of antibodies against our synthetic ape E (141-155) gave a positive immunoprecipitation line with Purified apolipoprotein E, which showed a partial identity with those obtained with polyclonal antibodies raised against the native protein. ...

Variable gene expression amongst transgenic lines occurs due to copy number and to random associations of incoming DNA with chromosomal elements at the site of integration. Here we describe a method of identifying sites permissive for transgene expression and their use for efficient introduction of single copy transgenes by homologous recombination. ES clones were selected in HAT medium for exp...

We present here new astrometric measurements of Algol's position made with Very Long Baseline Interferometry. Using these measurements, along with a new estimate of the node of the inner binary and other orbital elements from the literature, we compute a new proper motion, with uncertainties six times less than those of Hipparcos. We compute the trajectories of Algol (using the new proper motio...

BACKGROUND The microRNA-200 family participates in the maintenance of an epithelial phenotype and loss of its expression can result in epithelial to mesenchymal transition (EMT). Furthermore, the loss of expression of miR-200 family members is linked to an aggressive cancer phenotype. Regulation of the miR-200 family expression in normal and cancer cells is not fully understood. METHODOLOGY/P...
