Myositis is characterised by muscle inflammation and weakness. Although generally thought to be driven by a systemic autoimmune response, increasing evidence suggests that intrinsic changes in the muscle might also contribute to the pathogenesis. Long non-coding RNAs (lncRNAs) are a family of novel genes that regulate gene transcription and translation. To determine the potential role of lncRNAs, we employed next generation sequencing to examine the transcriptome in muscle biopsies obtained from two histologically distinct patient populations, inclusion body myositis (IBM) and anti-Jo-1-associated myositis (Jo-1)...

H19 is involved in tumor metastasis and associated with tumor progression. Enhancer of zest homolog 2 (EZH2) is overexpressed in multiple cancer types and correlates with tumor proliferation, epithelial-mesenchymal transition, and poor prognosis. However, the interaction between H19 and EZH2 to promote tongue squamous cell carcinoma (TSCC) progression remains largely uncharacterized. Insitu hybridization and quantitative reverse-transcription PCR (qRT-PCR) were performed to measure H19 expression in primary TSCC and adjacent normal tissues and cell lines...

We previously demonstrated that the nuclear form of Glutathione Peroxidase 4 (nGPx4) has a peculiar distribution in sperm head, being localized to nuclear matrix and acrosome and that sperm lacking nGPx4 are more prone to decondensation in vitro. In this study we have hypothesized that sperm retained acetylated histones and nGPx4 are implicated in paternal chromatin decondensation and male pronucleus formation at fertilization. Indeed, significant higher amounts of acetylated histone H4 and acetylated histone H3 were observed by both immunofluorescence and western blotting in nGPx4-KO sperm vs WT ones...

In recent years, long non-coding RNAs (lncRNAs) and microRNAs (miRNAs) have been shown to play important roles in tumor biological function. The aim of this study was to investigate the diagnostic and prognostic value of lncRNA H19 and miR-21 expression in non-small-cell lung cancer (NSCLC). H19 and miR-21 expression was measured in tumor tissues and corresponding non-tumor lung tissues from 200 patients by quantitative reverse transcription polymerase chain reaction. Moreover, the in vitro and in vivo effects of H19 knock out in A549 cells were investigated...

MicroRNAs (miRNAs) play important roles in the carcinogenesis of cervical cancer. However, the expression and underlying mechanisms of miRNA in cervical cancer progression remain unclear. In the present study, our data showed that the expression of miR-138-5p was significantly downregulated in cervical cancer tissues, decreased expression of miR-138-5p was correlated with advanced FIGO stage, poor differentiation, lymph nodes metastasis, and poor overall survival of cervical cancer patients. Function assays showed that overexpression of miR-138-5p reduced cervical cancer cell proliferation, arrested cell in G0/G1 phase and induced cell apoptosis in vitro...

Recent studies in animal models and humans show that long non-coding RNAs (lncRNAs) are involved in the development of atherosclerosis, which contributes to the pathological foundation of coronary artery disease (CAD). LncRNAs in plasma and serum have been considered as promising novel biomarkers for diagnosis and prognosis of cardiovascular diseases, especially CAD. We here measured the circulating levels of 8 individual lncRNAs which are known to be relevant to atherosclerosis in the plasma samples from 300 patients with CAD and 180 control subjects by using quantitative real-time reverse transcription-polymerase chain reaction (qRT-PCR) methods...

BACKGROUND: Extra-renal involvement in hemolytic uremic syndrome (HUS) includes gastrointestinal, pancreatic, hepatic, neurological and cardiac manifestations. The current 3-5% mortality rate in HUS patients is primarily attributed to complications related to the central nervous system and the heart. In this brief report, we illustrate that severe cardiac involvement in a patient with HUS is potentially reversible using cardiopulmonary bypass as rescue. CASE-DIAGNOSIS/TREATMENT: A 12-year-old boy was diagnosed with enterohemorrhagic Escherichia coli-induced HUS related to E...

Accumulating evidences indicate that long noncoding RNAs (lncRNAs) might play important roles in tumorigenesis and metastasis. EMT (epithelial-to-mesenchymal transition) is considered as a critical step in invasion and metastasis of various tumors including bladder cancer (BC). Recent researches have showed that lncRNA H19 is implicated in metastasis through regulating EMT and the reverse MET (mesenchymal-to-epithelial transition). However, underlying mechanisms remain largely unknown. Here, we screened lncRNA and mRNA expression profiles of BC with microarray assay...

Previous study has revealed that H19 expression is required for efficient tumor growth induced by BCR-ABL in chronic myeloid leukemia (CML). Herein, we further determined H19 expression and its clinical implication in patients with CML. H19 expression and methylation were detected by real-time quantitative PCR and real-time quantitative methylation-specific PCR, and then clinical implication of H19 expression was further analyzed. H19 expression was significantly up-regulated in CML patients (P < 0.001)...

Loss of imprinting (LOI) is an epigenetic event which relaxes an allele-specific restriction on gene expression. One gene that experiences LOI is the paracrine insulin-like growth factor IGF2, which occurs commonly in human prostate tissues during aging and tumorigenesis. However, the relationship between IGF2 LOI and prostate tumorigenesis has not been established functionally. In this study, we created a mouse model with CTCF binding site mutations at the Igf2-H19 imprint control region that abolishes CTCF insulator activity, resulting in biallelic Igf2 expression that mimics increased levels seen with aging-induced LOI...

Acute myelocytic leukemia (AML) is the most common type of acute leukemia. Long non‑coding RNAs (lncRNAs) serve an important role in regulating gene expression through chromatin modification, transcription and post‑transcriptional processing. LncRNA H19 was considered as an independent prognostic marker for patients with tumors. The expression of lncRNA H19 was identified to be significantly upregulated in bone marrow samples from patients with AML‑M2. Furthermore, it was demonstrated that the knockdown of lncRNA H19 resulted in increased expression of hsa‑microRNA (miR)‑19a/b and decreased expression of inhibitor of DNA binding 2 (ID2) in AML cells...

A Gram-staining-negative, long rod-shaped, non-motile, strictly aerobic bacterial strain, designated H19-56T, was isolated from a surface marine snow sample collected from the Yellow Sea near China. Phylogenetic analysis based on 16S rRNA gene sequences indicated that H19-56T represented a member of the genus Muricauda and showed the highest sequence similarity to Muricauda ruestringensis B1T (96.9 %). H19-56T grew optimally at pH 8.0, 32 °C and in the presence of 3 % (w/v) NaCl. The DNA G+C content was 43...

Considering the widespread use of assisted reproductive techniques (ART), DNA methylation of specific genes involved in spermatogenesis achieves increasingly clinical relevance, representing a possible explanation of increased incidence of syndromes related to genomic imprinting in medically assisted pregnancies. Several trials suggested a relationship between male sub-fertility and sperm DNA methylation, although its weight on seminal parameters alteration is still a matter of debate. To evaluate whether aberrant sperm DNA methylation of imprinted genes is associated with impaired sperm parameters...

The Beckwith-Wiedemann syndrome is a cancer predisposition syndrome characterized by a predilection to embryonal tumor growth, especially Wilms tumor, adrenocortical carcinomas, and hepatoblastomas. Genetic analysis of patients has revealed a link to the imprinted domain of the 11p15.5 chromosome and methylation status of the H19 locus and Igf-2. These genes have also been studied in other cancers, including ovarian teratomas. Our case is a patient with a simultaneous presentation of a Wilms tumor and immature ovarian teratoma and subsequently diagnosed with Beckwith-Wiedemann syndrome, which has not been previously described...

Ubiquitination-directed protein degradation is important in many cancers for tumor initiation and maintenance, and E3 ligases containing HECT domains are emerging as new therapeutic targets. In contrast to many other E3 ligases, the role of HUWE1 in ovarian cancer where HUWE1 is dysregulated has been unclear. Here we report that genetic deletion of Huwe1 in the mouse inhibits transformation of ovary surface epithelium cells without significantly affecting cell survival and apoptosis, and that Huwe1 deletion after tumors have been initiated inhibits tumor growth...

BACKGROUND/OBJECTIVE: Vitamin D deficiency during pregnancy is associated with poor birth outcomes in some studies, but few have examined weight beyond birth. Additionally, little is known about how vitamin D influences DNA methylation of regulatory regions known to be involved in growth, as possible mediators to weight status in offspring. SUBJECTS/METHODS: We conducted linear regressions to assess maternal plasma 25-hydroxyvitamin D (25(OH)D) by quartile and birth weight for gestational age z-score, 1-year weight-for-length z-score, and 3-year body mass index (BMI) z-score among 476 mother/infant dyads from a prospective cohort...

The paternal-allele-specific methylation of the Igf2/H19 imprinting control region (ICR) is established during gametogenesis and maintained throughout development. To elucidate the requirement of the germline passage in the maintenance of the imprinting methylation, we established a system introducing a methylated or unmethylated ICR-containing DNA fragment (ICR-F) into the paternal or maternal genome by microinjecting into the paternal or maternal pronucleus of fertilized eggs, and traced the methylation pattern in the ICR-F...
