BACKGROUND/AIMS: Long noncoding RNAs (lncRNAs) are aberrantly expressed in multiple malignant tumors involved in tumor growth and metastasis. Accumulating data show that small nucleolar RNA host gene (SNHG) 1/12/20 plays a key role in the progression of hepatocellular carcinoma (HCC). However, the molecular mechanisms by which SNHG8 contributes to HCC remain elusive and merit exploration. METHODS: The association between SNHG8 expression and the clinicopathological characteristics and prognoses in HCC patients was analysed by using qRT-PCR analysis and the data from The Cancer Genome Atlas...

In this issue of Cancer Cell, Gerhauser et al. analyze early-onset prostate cancers, showing roles for androgen receptor-driven rearrangements, an early APOBEC-driven mutational mechanism, and ESRP1 gene duplication. Through integration of whole-genome, transcriptome, and methylome data, they identify high-risk subgroups and develop an algorithm that may predict molecular evolution.

Idiopathic pulmonary fibrosis (IPF) is a life-threatening progressive disease characterized by loss of alveolar epithelial cells, inflammation and aberrant fibroblast activation. The two currently approved therapies do not halt or reverse tissue remodeling and therefore novel disease modifying mechanisms are needed. Our results describe YAP/TAZ inhibition through IP receptor activation as a novel mechanism that suppresses pro-fibrotic (myo)fibroblast activity. We investigated the anti-fibrotic properties of the selective prostacyclin (IP) receptor agonist ACT-333679 using primary human lung fibroblasts...

Angioedema is a rare adverse effect of the commonly used angiotensin converting enzyme inhibitors (ACEi) and is reported to occur with a prevalence of 0.1 - 0.7%. Although most ACEi-induced angioedema (ACEi-A) cases are mild, severe cases requiring intensive care and even resulting in death have been reported in the literature. The mechanisms underlying ACEi-A are not yet fully understood, but bradykinin and/or substance P accumulation resulting from inhibition of ACE, is believed to play a crucial role. ACEi-A occurs at variable frequencies across different racial groups, suggesting a genetic association to the development of ACEi-A...

Some lncRNAs can encode small nucleolar RNAs (snoRNAs), called small nucleolar RNA host genes (SNHGs), which exert diverse regulatory effects on cellular processes. In this study, using RNA-seq and survival data in the Cancer Genome Atlas (TCGA)-Liver Hepatocellular Carcinoma (LIHC), we examined the expression profile of some SNHG genes and explored their prognostic value in hepatocellular carcinoma (HCC). Level-3 RNA-sequencing data, the clinicopathological and survival data of patients with primary HCC were downloaded from the UCSC Xena browser (https://xenabrowser...

The male-biased prevalence of certain neurodevelopmental disorders and the sex-biased outcomes associated with stress exposure during gestation have been previously described. Here, we hypothesized that genes distinctively targeted by only one or both homologous proteins highly conserved across therian mammals, SOX3 and SRY, could induce sexual adaptive changes that result in a differential risk for neurodevelopmental disorders. ChIP-seq/chip data showed that SOX3/SRY gene targets were expressed in different brain cell types in mice...

We develop linear mixed models (LMMs) and functional linear mixed models (FLMMs) for gene-based tests of association between a quantitative trait and genetic variants on pedigrees. The effects of a major gene are modeled as a fixed effect, the contributions of polygenes are modeled as a random effect, and the correlations of pedigree members are modeled via inbreeding/kinship coefficients. <mml:math xmlns:mml="http://www.w3.org/1998/Math/MathML"> <mml:mi>F</mml:mi> </mml:math> -statistics and χ 2 likelihood ratio test (LRT) statistics based on the LMMs and FLMMs are constructed to test for association...

Tamoxifen treatment is important assistant for estrogen-receptor-positive breast cancer (BRCA) after resection. This study aimed to identify signatures for predicting the prognosis of patients with BRCA after tamoxifen treatment. Data of gene-specific DNA methylation (DM), as well as the corresponding clinical data for the patients with BRCA, were obtained from The Cancer Genome Atlas and followed by systematic bioinformatics analyses. After mapping these DM CPG sites onto genes, we finally obtained 352 relapse-free survival (RFS) associated DM genes, with which 61,776 gene pairs were combined, including 1,614 gene pairs related to RFS...

During the past three decades, the study of nuclear and chromatin organization has become of great interest. The organization and dynamics of chromatin are directly responsible for many functions including gene regulation, genome replication, and maintenance. In order to better understand the details of these mechanisms, we need to understand the role of specific proteins that take part in these processes. The genome in the nucleus is organized in different length scales, ranging from the bead-like nucleosomes through topological associated domains (TADs) up to chromosome territories...

In vascular (Arabidopsis thaliana) and nonvascular (Physcomitrella patens) plants, PHOSPHATE 1 (PHO1) homologs play important roles in the acquisition and transfer of phosphate. The tomato genome contains six genes (SlPHO1;1-SlPHO1;6) homologous to AtPHO1. The six proteins have typical characteristics of the plant PHO1 family, such as the three SPX sub domains in the N-terminal portion and one EXS domain in the C-terminal portion. Phylogenetic analysis revealed that the SlPHO1 family is subdivided into three clusters...

Parasitism is a life strategy that has repeatedly evolved within the Florideophyceae. Historically, the terms adelphoparasite and alloparasite have been used to distinguish parasites based on the relative phylogenetic relationship of host and parasite. However, analyses using molecular phylogenetics indicate that nearly all red algal parasites infect within their taxonomic family, and a range of relationships exist between host and parasite. To date, all investigated adelphoparasites have lost their plastid, and instead, incorporate a host derived plastid when packaging spores...

The cause of colorectal cancer (CRC) is multifactorial, involving both genetic variants and environmental risk factors. We systematically searched the MEDLINE, EMBASE, China National Knowledge Infrastructure (CNKI) and Wanfang databases from inception to December 2016, to identify systematic reviews and meta-analyses of observational studies that investigated gene-environment (G × E) interactions in CRC risk. Then, we critically evaluated the cumulative evidence for the G × E interactions using an extension of the Human Genome Epidemiology Network's Venice criteria...

DNA methylation is a crucial regulator of gene transcription in the etiology and pathogenesis of hepatocellular carcinoma (HCC). Thus, it is reasonable to identify DNA methylation-related prognostic markers. Currently, we aimed to make an integrative epigenetic analysis of HCC to identify the effectiveness of epigenetic drivers in predicting prognosis for HCC patients. By the software pipeline TCGA-Assembler 2, RNA-seq, and methylation data were downloaded and processed from The Cancer Genome Atlas. A bioconductor package MethylMix was utilized to incorporate gene expression and methylation data on all 363 samples and identify 589 epigenetic drivers with transcriptionally predictive...

Mutations in the X-linked gene MECP2 are associated with a severe neurodevelopmental disorder, Rett syndrome (RTT), primarily in girls. It had been suspected that mutations in Methyl-CpG-binding protein 2 (MECP2) led to embryonic lethality in males, however such males have been reported. To enhance understanding of the phenotypic spectrum present in these individuals, we identified 30 males with MECP2 mutations in the RTT Natural History Study databases. A wide phenotypic spectrum was observed, ranging from severe neonatal encephalopathy to cognitive impairment...

Bacterial genes for molybdenum-containing and tungsten-containing enzymes are often differentially regulated depending on the metal availability in the environment. Here, we describe a new family of transcription factors with an unusual DNA-binding domain related to excisionases of bacteriophages. These transcription factors are associated with genes for various molybdate and tungstate-specific transporting systems as well as molybdo/tungsto-enzymes in a wide range of bacterial genomes. We used a combination of computational and experimental techniques to study a member of the TF family, named TaoR (for tungsten-containing aldehyde oxidoreductase regulator)...
