Human T-lymphotropic virus type-1 (HTLV-1) is the causative agent of adult T-cell leukaemia/lymphoma (ATL), an aggressive CD4+ T-cell malignancy. The mechanisms of leukaemogenesis in ATL are incompletely understood. Insertional mutagenesis has not previously been thought to contribute to the pathogenesis of ATL. However, the recent discovery that HTLV-1 binds the key chromatin architectural protein CTCF raises the hypothesis that HTLV-1 deregulates host gene expression by causing abnormal chromatin looping, bringing the strong HTLV-1 promoter-enhancer near to host genes that lie up to 2Mb from the integrated provirus...

Breast cancer represents a heterogeneous collection of diseases with disparate clinical behaviors, responses to treatment, and patient outcomes, despite common histopathological features at diagnosis. Examination of molecular signatures of breast cancer (based upon complex gene expression patterns) enabled identification of several intrinsic molecular subtypes: luminal A, luminal B, HER2-enriched, and basal-like. The intrinsic subtypes are associated with measures of clinical aggressiveness, but do not perfectly predict patient outcomes...

DNA methylation is one of the main epigenetic modifications in the eukaryotic genome; it has been shown to play a role in cell-type specific regulation of gene expression, and therefore cell-type identity. Bisulfite sequencing is the gold-standard for measuring methylation over the genomes of interest. Here, we review several techniques used for the analysis of high-throughput bisulfite sequencing. We introduce specialized short-read alignment techniques as well as pre/post-alignment quality check methods to ensure data quality...

Gastrointestinal stromal tumor (GIST), the most common mesenchymal neoplasm of the gastrointestinal tract, exhibits diverse histologic and clinical manifestations. With its putative origin in the gastrointestinal pacemaker cell of Cajal, GIST can arise in association with any portion of the tubular gastrointestinal tract. Morphologically, GISTs are classified as spindled or epithelioid, though each of these subtypes encompasses a broad spectrum of microscopic appearances, many of which mimic other histologic entities...

Covering: 2006 to 2017Actinomycetes have been, for decades, one of the most important sources for the discovery of new antibiotics with an important number of drugs and analogs successfully introduced in the market and still used today in clinical practice. The intensive antibacterial discovery effort that generated the large number of highly potent broad-spectrum antibiotics, has seen a dramatic decline in the large pharma industry in the last two decades resulting in a lack of new classes of antibiotics with novel mechanisms of action reaching the clinic...

Chimeric antigen receptor-modified T cells (CAR-T) are endowed with cytotoxic specificity to tumor cells. Although CAR-T-based cancer immunotherapy presents curable therapeutic potential for hematological malignancies, achieving substantial efficacy for solid tumors remain challenging. Researchers have exploited many strategies to enhance the anti-tumor efficacy of CAR-T cells for solid tumors, among which cytokine-armed CAR-T cells improve the proliferation, survival, homing and other properties of CAR-T cells...

REVIEW
Jeffrey R Liddell
Nuclear factor erythroid 2-related factor 2 (Nrf2) is a transcription factor that regulates hundreds of antioxidant genes, and is activated in response to oxidative stress. Given that many neurodegenerative diseases including Alzheimer's disease, Parkinson's disease, amyotrophic lateral sclerosis, Huntington's disease and multiple sclerosis are characterised by oxidative stress, Nrf2 is commonly activated in these diseases. Evidence demonstrates that Nrf2 activity is repressed in neurons in vitro, and only cultured astrocytes respond strongly to Nrf2 inducers, leading to the interpretation that Nrf2 signalling is largely restricted to astrocytes...

Blood flow provides endothelial cells (ECs) lining the inside of blood vessels with mechanical stimuli as well as humoral stimuli. Fluid shear stress, the frictional force between flowing blood and ECs, is recognized as an essential mechanical cue for vascular growth, remodeling, and homeostasis. ECs differentially respond to distinct flow patterns. High laminar shear flow leads to inhibition of cell cycle progression and stabilizes vessels, whereas low shear flow or disturbed flow leads to increased turnover of ECs and inflammatory responses of ECs prone to atherogenic...

Peroxisome proliferator-activated receptors (PPARs) are ligand-activated nuclear receptors that are widely involved in various physiological functions. They are widely expressed through the reproductive system. Their roles in the metabolism and function of sex steroids and thus the etiology of reproductive disorders receive great concern. Various kinds of exogenous chemicals, especially environmental pollutants, exert their adverse impact on the reproductive system through disturbing the PPAR signaling pathway...

BACKGROUND: Pyridoxal-5(')-phosphate oxidase (PNPO) deficiency presents as a severe neonatal encephalopathy responsive to pyridoxal-5(')-phosphate (PLP) or pyridoxine. Recent studies widened the phenotype of this condition and detected genetic variants on PNPO gene whose pathogenic role and clinical expression remain to be established. OBJECTIVE: This paper aims to characterize the functional effects of the c.347G>A (p.Arg116Gln) mutation in the PNPO gene in order to define its pathogenicity and describe the clinical features of new patients with epilepsy carrying this mutation...

The plant kingdom produces a variety of fatty acid structures, many of which possess functional groups useful for industrial applications. The species that produce these unusual fatty acids are often not suitable for large scale commercial production. The ability to create genetically modified plants, together with emerging synthetic biology approaches, offers the potential to develop alternative oil seed crops capable of producing high levels of modified lipids. In some cases, by combining genes from different species, non-natural lipids with a targeted structure can be conceived...

REVIEW

Cytomixis, is a form of cell-to-cell nuclear migration that involves the interaction of dynamic cytoskeletal components with the nucleus through signalling systems and linker complexes. In cytomixis two known mechanisms can be involved: actomyosin and/or microtubules and their associated motors. Perinuclear actin anchors and determines the direction of nuclear movement. In microsporogenesis cytomixis is probably initiated by a cascade of signals that trigger prophase reorganization of nucleus and cytoskeleton, and is a result of cytoskeletal protein activation, as well as a weakening of mechanisms responsible for anchoring the nucleus...

SIGNIFICANCE: RNA is a heterogeneous class of molecules with the minority being protein coding. Non-coding RNAs (ncRNA) are involved in translation and epigenetic control mechanisms of gene expression. Recent Advances: Within recent years the number of identified ncRNAs has dramatically increased and it is now clear that ncRNAs provide a complex layer of differential gene expression control. CRITICAL ISSUES: NcRNAs exhibit interplay with redox-regulation. Redox-regulation alters the expression of ncRNAs; conversely, ncRNAs alter the expression of generator and effector systems of redox regulation in a complex manner, which will be the focus of this review article...

AIMS: Carbon monoxide (CO)-releasing molecules (CORMs) are candidates for animal and antimicrobial therapeutics. We aimed to probe the antimicrobial potential of a novel manganese CORM. RESULTS: [Mn(CO)4S2CNMe(CH2CO2H)], CORM-401, inhibits growth of Escherichia coli and several antibiotic-resistant clinical pathogens. CORM-401 releases CO that binds oxidases in vivo but is an ineffective respiratory inhibitor. Extensive CORM accumulation (assayed as intracellular manganese) accompanies antimicrobial activity...

Uterine diseases are common in dogs, particularly in countries where elective spaying is not usually performed. The associated clinical illnesses may be of varying degree ranging from merely decreased fertility to a critical pyometra requiring intensive care to survive. The diagnosis of some uterine diseases is generally uncomplicated, such as in a classic pyometra presenting with enlarged, fluid-filled uterus, purulent vaginal discharge and characteristic signs of illness or in other disorders associated with uterine enlargement...

The fruit fly, Drosophila melanogaster, has been a favorite experimental system of developmental biologists for more than a century. One of the most attractive features of this model system is the clarity by which one can analyze mutant phenotypes. Most genes are found in single copies, and loss-of-function mutants often have obvious phenotypes that can be analyzed during development and in adulthood. As with all metazoans, a significant fraction of Drosophila genes are used during both embryonic and postembryonic development, and null mutants often die during embryogenesis thereby precluding the analysis of postembryonic tissues...

REVIEW
Anders Vahlquist, Judith Fischer, Hans Törmä
Hereditary ichthyoses are due to mutations on one or both alleles of more than 30 different genes, mainly expressed in the upper epidermis. Syndromic as well as nonsyndromic forms of ichthyosis exist. Irrespective of etiology, virtually all types of ichthyosis exhibit a defective epidermal barrier that constitutes the driving force for hyperkeratosis, skin scaling, and inflammation. In nonsyndromic forms, these features are most evident in severe autosomal recessive congenital ichthyosis (ARCI) and epidermolytic ichthyosis, but to some extent also occur in the common type of non-congenital ichthyosis...

Because of advances in the understanding of histological and molecular characteristics in ovarian cancer, it is now possible to recognize the existence of five subtypes, which in turn has allowed a more refined therapeutic approach and better design of clinical trials. Each of these five subtypes has specific histological features and a particular biomarker expression, as well as mutations in different genes, some of which have prognostic and predictive value. CA125 and HE4 are examples of ovarian cancer biomarkers used in the diagnosis and follow-up of these malignancies...

REVIEW
Samuel T Jerram, Mary N Dang, R David Leslie
PURPOSE OF REVIEW: Epigenetics is defined as mitotically heritable changes in gene expression that do not directly alter the DNA sequence. By implication, such epigenetic changes are non-genetically determined, although they can be affected by inherited genetic variation. Extensive evidence indicates that autoimmune diseases including type 1 diabetes are determined by the interaction of genetic and non-genetic factors. Much is known of the genetic causes of these diseases, but the non-genetic effects are less clear-cut...

We describe here the extraction of country-of-origin, an acculturation variable relevant for gene-environment studies, in a biorepository linked to de-identified electronic health records (EHRs) assessed by the Epidemiologic Architecture for Genes Linked to Environment (EAGLE), a study site of the Population Architecture using Genomics and Epidemiology (PAGE) I study. We extracted country-of-origin from the unstructured clinical free text using regular expressions within the MySQL relational database system in a cohort of 15,863 subjects of mostly non-European descent (including 11,519 African Americans, 1,702 Hispanics, and 1,118 Asians)...
