REVIEW
David J Paton, Simon Gubbins, Donald P King
Foot-and-mouth disease (FMD) is highly infectious, but despite the large quantities of FMD virus released into the environment and the extreme susceptibility of host species to infection, transmission is not always predictable. Whereas virus spread in endemic settings is characterised by frequent direct and indirect animal contacts, incursions into FMD-free countries may be seeded by low-probability events such as fomite or wind-borne aerosol routes. There remains a void between data generated from small-scale experimental studies and our ability to reliably reconstruct transmission routes at different scales between farms, countries and regions...

Breast cancer is indisputably a heterogeneous disease, in which a formidable combination of definitely dis-regulated C-MYC and microRNA (miRNA) profiles along with other factors are responsible to generate a specific type of breast cancer. C-MYC as a master regulator of more than 20,000 genes can modify the expression of genes underlying to perform diverse conflicting functional frameworks. The functional spectra of miRNA in the new areas of the evolution of cell behaviors are identified. Here, we endeavor to summarize some recent advances of miRNA applications that can be recruited as combinatorial targeted therapy for patients with breast cancer...

Myelodysplastic syndromes (MDS) are a heterogeneous group of diseases with varying genetic aberrations. Half of MDS patients have normal karyotype, obscuring the underlying condition indicating a need for new markers for improved diagnostics and prognosis. We performed a retrospective review of sequential MDS patients who underwent chromosomal genetic array testing (CGAT) between November 2008 and March 2014. Total Genomic Aberration (TGA) scores, with and without copy-neutral loss of heterozygosity (cnLOH), were compared to pathology and clinical data...

To ensure that the genetic material is accurately passed down to daughter cells during mitosis, dividing cells must duplicate their chromosomes and centrosomes once and only once per cell cycle. The same key steps-licensing, duplication, and segregation-control both the chromosome and the centrosome cycle, which must occur in concert to safeguard genome integrity. Aberrations in genome content or centrosome numbers lead to genomic instability and are linked to tumorigenesis. Such aberrations, however, can also be part of the normal life cycle of specific cell types...

Chikungunya virus (CHIKV) is a mosquito-borne virus that causes epidemics widely in the world especially in the tropical and subtropical regions. Phylogenetic analysis has found that the CHIKV lineages were associated with the spatial and temporal distributions, which were related to the virus adaption to the major mosquito species and their distributions. In this study, we reported the complete genome sequences of eight CHIKV isolates from the outbreak in Pakistan last year. Then we reviewed the evolutionary history using extensive phylogenetic analysis, analyzed lineagespecific substitutions in viral proteins, and characterized the spreading pathway of CHIKV strains including the Pakistani strains...

Introduction: Renal cell carcinoma (RCC) is the most common malignancy to metastasize to the thyroid gland. The aims of this study are as follows: (1) to analyze the clinical characteristics of patients with thyroid involvement of RCC and (2) in patients with RCC thyroid metastasis, to determine whether RCC metastasis to glandular organs only portends a better prognosis compared with other patterns of RCC metastasis. Methods: Patients from Wake Forest Baptist Medical Center (WFBMC) diagnosed with thyroid metastasis from RCC were identified and medical records retrospectively examined...

BACKGROUND: Prostate cancer (PC) is one of the known heritable cancers with individual variations attributed to genetic factors. BRCA1 and BRCA2 are tumour suppressor genes with crucial roles in repairing DNA and thereby maintaining genomic integrity. Germline BRCA mutations predispose to multiple familial tumour types including PC. METHODS: We performed a Pubmed database search along with review of reference lists from prominent articles to capture papers exploring the association between BRCA mtuations and prostate cancer risk and prognosis...

The majority of the human genome encodes RNAs that do not code for proteins. These non-coding RNAs (ncRNAs) affect normal expression of the genes, including oncogenes and tumour suppressive genes, which make them a new class of targets for drug development in cancer. Although microRNAs (miRNAs) are the most studied regulatory ncRNAs to date, and miRNA-targeted therapeutics have already reached clinical development, including the mimics of the tumour suppressive miRNAs miR-34 and miR-16, which reached phase I clinical trials for the treatment of liver cancer and mesothelioma, the importance of long non-coding RNAs (lncRNAs) is increasingly being recognised...

The emergence of immunotherapy has revolutionized cancer treatment in recent years. Inhibitors of immune checkpoints, including antibodies against cytotoxic T-lymphocyte-associated protein 4, programmed cell death protein 1, and programmed death ligand 1, have demonstrated notable efficacy in certain advanced cancers. Unfortunately, many patients do not benefit from these therapies and either exhibit primary resistance to treatment or develop acquired mechanisms of resistance after initially responding to therapy...

Cancer risk assessment of therapeutics is plagued by poor translatability of rodent models of carcinogenesis. In order to overcome this fundamental limitation, new approaches are needed that enable us to evaluate cancer risk directly in humans and human-based cellular models. Our enhanced understanding of the mechanisms of carcinogenesis and the influence of human genome sequence variation on cancer risk motivates us to re-evaluate how we assess the carcinogenic risk of therapeutics. This review will highlight new opportunities for applying this knowledge to the development of a battery of human-based in vitro models and biomarkers for assessing cancer risk of novel therapeutics...

Nitric oxide (NO) is a key signaling molecule in plant physiology. However, its production in photosynthetic organisms remains partially unresolved. The best characterized NO production route involves the reduction of nitrite to NO via different non-enzymatic or enzymatic mechanisms. Nitrate reductases (NRs), the mitochondrial electron transport chain, and the new complex between NR and NOFNiR (nitric oxide-forming nitrite reductase) described in Chlamydomonas reinhardtii are the main enzymatic systems that perform this reductive NO production in plants...

Numerous studies have shown associations between genetic variants and neuropathic pain disorders. Rare monogenic disorders are caused by mutations of substantial effect size in a single gene, whereas common disorders are likely to have a contribution from multiple genetic variants of mild effect size, representing different biological pathways. In this review, we survey the reported genetic contributors to neuropathic pain and submit them for validation in a 150,000-participant sample of the U.K. Biobank cohort...

Recent technological development has enabled fast and cost-effective simultaneous analyses of several gene variants or sequence of even the whole genome. For medical practitioners this has created challenges although genomic information may be clinically useful in new applications such as finding out individual risk for diseases influenced by as many as 50,000 variable DNA regions or in detecting pharmacogenetic risks prior to prescribing a medicine. New digital tools have paved the way for utilization of genomic data via easy access and clear clinical interpretation for both doctor and patient...

The scientific advances in the past few years have enabled individualized prevention and treatment of diseases on the basis of genome-wide information. For example, dozens of genomic regions affecting the risk for coronary artery disease have been identified. Both Finnish and international longitudinal studies show that the risk assessment of coronary artery disease can be significantly improved if the estimate is based both on the newly discovered hereditary risk factors and the long-recognized traditional risk factors, e...

Long non-coding RNAs, produced from distinct regions of the chromosomes, are emerging as new key players in several important biological processes. The long non-coding RNAs add a new layer of complexity to cellular regulatory pathways, from transcription to cellular trafficking or chromatin remodeling. More than 25 years ago, the discovery of a transcriptional activity at telomeres of protozoa ended the long-lasting belief that telomeres were transcriptionally silent. Since then, progressively accumulating evidences established that production of TElomeric Repeat-containing RNA (TERRA) was a general feature of eukaryotic cells...

The Wilms' tumour gene 1 protein (WT1) is a zinc finger transcription factor found indispensable for foetal development. WT1 has also been implicated in the development of tumours in several organ systems, including acute myeloid leukaemia (AML). Four main WT1 isoforms come from two alternative splice events. One alternative splice results in the inclusion or exclusion of three amino acids, KTS, between zinc fingers three and four in the WT1 protein. The KTS insert has been extensively investigated due to the functional implications for DNA and RNA binding...

Breast cancer is an important cause of cancer related mortality in women. Despite extensive efforts to identify valid biomarkers for risk stratification, there are relatively few with proven clinical utility. It is recognized that genetic factors play a major role in determining susceptibility to breast cancer. Recent genome-wide-association-studies and gene expression analysis have demonstrated that a locus on chromosome 9p21, which contains three genes; CDKN2B (encoding p15ink4b), CDKN2A (encoding p16ink4a and p14ARF) and the 3' end of CDKN2BAS [an antisense noncoding RNA in the INK4 locus (ANRIL)] are associated with an increased risk of this malignancy...

Long interspersed element-1 (LINE-1 or L1) is a transposable element with the ability to self-mobilize throughout the human genome. The L1 elements found in the human brain is hypothesized to date back 56 million years ago and has survived evolution, currently accounting for 17% of the human genome. L1 retrotransposition has been theorized to contribute to somatic mosaicism. This review focuses on the presence of L1 in the healthy and diseased human brain, such as in autism spectrum disorders (ASD). Throughout this exploration, we will discuss the impact L1 has on neurological disorders that can occur throughout the human lifetime...
