OBJECTIVES The outer membrane protein M35 of Moraxella catarrhalis is an antigenically conserved porin. Knocking out M35 significantly increases the MICs of aminopenicillins. The aim of this study was to determine the biological mechanism of this potentially new antimicrobial resistance mechanism of M. catarrhalis and the behaviour of M35 in general stress situations. METHODS PCR using m35-sp...

Deregulation of long noncoding RNAs (lncRNAs) is becoming recognized as a major feature of many neurological disorders. In the current study, we aimed to measure the expression of seven lncRNAs and lncRNA-targeted mRNAs in the peripheral lymphocytes of attention-deficit/hyperactivity disorder (ADHD), autism spectrum disorder (ASD), and intellectual disability (ID) patients via quantitative real...

BACKGROUND/AIMS MicroRNA (miRNA) plays important roles in the development of different cancers. In this study, we investigated the roles and mechanisms of miR-203 in human cervical cancer. METHODS miR-203 expression was detected in cervical cancer tumors and cell lines by qRT-PCR. The methylation status in the promoter region of miR-203 was examined by methylation-specific PCR. The functional...

Microarrays were used to identify genes of Porphyromonas gingivalis W83 differentially expressed during invasion of primary human coronary artery endothelial cells. Analyses of microarray images indicated that 62 genes were differentially regulated. Of these, 11 genes were up-regulated and 51 were down-regulated. The differential expression of 16 selected genes was confirmed by real-time PCR.

Osteoporosis is a common bone disease that has a strong genetic component. Genome-wide linkage studies have identified the chromosomal region 3p14-p22 as a quantitative trait locus for bone mineral density (BMD). We have previously identified associations between variation in two related genes located in 3p14-p22, ARHGEF3 and RHOA, and BMD in women. In this study we performed knockdown of these...

PURPOSE Hedgehog (Hh) signaling is activated in several cancers. However, the mechanisms of Hh signaling activation in hepatocellular carcinoma (HCC) have not been fully elucidated. We analyzed the involvement of Hh-interacting protein (HHIP) gene, a negative regulator of Hh signaling, in HCC. EXPERIMENTAL DESIGN Glioma-associated oncogene homologue (Gli) reporter assay, 3-(4,5-dimethylthiazo...

objectives: stigma is a negative value. many behaviors are to ward stigmatized people. down syndrome is one of conditions with stigma. the aim of this study is to determine the sources of labeling in iranian down syndrome. methods: the view of 105 down syndrome families concerning stigma were conducted. all of down syndrome was under 50 years. results: a fair proportion of down syndrome familie...

abstract isolated tuberculosis (tb) liver abscesses have rarely been documented in the literature.this report describes the challenging diagnosis of primary liver tb. we report on the case of a 10-year-old girl with down syndrome, who had symptoms of fever and chills, anorexia and intermittent vomiting. the ultrasound and computed tomography (ct)revealed multiple abscess-like lesions in the liv...

This study was to uncover the role of long non-coding RNA (lncRNA) in the process of endometrial cancer (EC) development using microarray technique to obtain the expression profiles of lncRNAs in EC and its adjacent normal tissues. A total of 45 pieces of pathologically-proven EC tissues were used in this study. All samples were frozen in liquid nitrogen immediately after resection and stored a...

The Tuber melanosporum genome has been analysed with the aim of identifying and characterizing the genes involved in the environmental stress response. A whole genome array (7496 genes/probe) was used to verify the fungal transcriptional profiling upon a cold temperature period (7 days at 4 °C). A total of 423 genes resulted to be differentially expressed in a significant manner (>2.5-fold; p-v...
