[Genetic profiling in the diagnosis of hereditary prostate cancer: Where do we stand?]

Aktuelle Urol 2018 Dec 6;49(6):525-529. Epub 2018 Dec 6.

Johannes Gutenberg Universitat Universitatsmedizin, Klinik und Poliklinik für Urologie und Kinderurologie, Mainz.

Prostate cancer has a heterogeneous genetic profile compared with other tumour entities. Accordingly, there are also various mutations that increase the risk of prostate cancer. Some genetic variants only have a mild impact, whereas other gene mutations (BRCA1 /2; HOXB13) may increase the risk significantly. Read More

Myofascial Pain.

Semin Neurol 2018 Dec 6;38(6):640-643. Epub 2018 Dec 6.

Department of Neurology, Boston University School of Medicine, Boston, Massachusetts.

Myofascial pain syndromes arise from acute and chronic musculoskeletal pain and often have a referred neuropathic component. It affects more than three quarters of the world's population and is one of the most important and overlooked causes of disability. The origins of pain are thought to reside anywhere between the motor end plate and the fibrous outer covering of the muscle, with involvement of microvasculature and neurotransmitters at the cellular level.

Photoinactivation of the Staphylococcus aureus Lactose-Specific EIICB Phosphotransferase Component with p-azidophenyl-β-D-Galactoside and Phosphorylation of the Covalently Bound Substrate.

J Mol Microbiol Biotechnol 2018 Dec 6;28(3):147-158. Epub 2018 Dec 6.

Max Planck Institute for Systems Physiology, Dortmund,

Background: The phosphoenolpyruvate (PEP):lactose phosphotransferase system of Staphylococcus aureus transports and phosphorylates lactose and various phenylgalactosides. Their phosphorylation is catalyzed by the Cys476-phosphorylated EIIB domain of the lactose-specific permease enzyme IICB (EIICBLac). Phosphorylation causes the release of galactosides bound to the EIIC domain into the cytoplasm by a mechanism not yet understood. Read More

Reasonable expectations of privacy in non-disclosure of familial genetic risk: What is it reasonable to expect?

Authors:
Victoria Chico

Eur J Med Genet 2018 Dec 3. Epub 2018 Dec 3.

Society and Ethics Research Group, Connecting Science, Wellcome Genome Campus, Cambridge, UK. Electronic address:

Where there is conflict between a patient's interests in non-disclosure of their genetic information to relatives and the relative's interest in knowing the information because it indicates their genetic risk, clinicians have customarily been able to protect themselves against legal action by maintaining confidence even if, professionally, they did not consider this to be the right thing to do. In ABC v St Georges Healthcare NHS Trust ([2017] EWCA Civ 336) the healthcare team recorded their concern about the wisdom of the patient's decision to withhold genetic risk information from his relative, but chose to respect what they considered to be an unwise choice. Even though professional guidance considers that clinicians have the discretion to breach confidence where they believe this to be justified, (Royal College of Physicians, Royal College of Pathologists and the British Society of Human Genetics, 2006; GMC, 2017) clinicians find it difficult to exercise this discretion in line with their convictions against the backdrop of the legal prioritisation of the duty to maintain confidence.

In Vitro Synthesis and Crystallization of β-1,4-Mannan.

Biomacromolecules 2018 Dec 6. Epub 2018 Dec 6.

In vitro polymerization of β-mannans is a challenging reaction due to the steric hindrance confered by the configuration of mannosyl residues and the thermodynamic instability of the β-anomer. Whatever the approach used to date - whether chemical, or enzymatic with glycosynthases and mannosyltransferases - pure β-1,4-mannans have never been synthesized in vitro. This has limited attempts to investigate their role in the production of plant and algal cell walls, in which they are highly abundant. Read More

Introduction of D-Amino Acids in Minimalistic Peptide Substrates by an S-Adenosyl-L-Methionine Radical Epimerase.

Angew Chem Int Ed Engl 2018 Dec 6. Epub 2018 Dec 6.

ETH Zürich, Department of Biology, Vladimir-Prelog-Weg 4, 8093, Zürich, SWITZERLAND.

Post-translational modifying enzymes from the S-adenosyl-L-methionine (AdoMet) radical superfamily garner attention due to their ability to accomplish challenging biochemical reactions. Among them, a family of AdoMet radical epimerases catalyze irreversible L- to D-amino acid transformations of diverse residues, including 18 sites in the complex sponge-derived polytheonamide toxins. These enzymes are from the proteusin family of ribosomally synthesized and post-translationally modified peptide natural products and act on precursor proteins with relatively large N-terminal leaders and highly variable core sequences.

The SOCS family are key negative regulators of cytokine and growth factor signalling. Typically 8-17 SOCS genes are present in vertebrate species and eight known in mammals, classified as type I (SOCS4-7) and type II (CISH and SOCS1-3) SOCS. It was believed that the type II SOCS were expanded through the two rounds of whole genome duplication (1R and 2R WGDs) from a single CISH/SOCS1-3 precursor. Read More

An RK/ST C-terminal Motif is Required for Targeting of OEP7.2 and a Subset of Other Arabidopsis Tail-Anchored Proteins to the Plastid Outer Envelope Membrane.

Plant Cell Physiol 2018 Dec 5. Epub 2018 Dec 5.

Department of Molecular and Cellular Biology, University of Guelph, Guelph, Ontario, Canada.

Tail-anchored (TA) proteins are a unique class of integral membrane proteins that possess a single C-terminal transmembrane domain and target post-translationally to the specific organelles at which they function. While significant advances have been made in recent years in elucidating the mechanisms and molecular targeting signals involved in the proper sorting of TA proteins, particularly to the endoplasmic reticulum and mitochondria, relatively little is known about the targeting of TA proteins to the plastid outer envelope. Here we show that several known or predicted plastid TA outer envelope proteins (OEPs) in Arabidopsis possess a C-terminal RK/ST sequence motif that serves as a conserved element of their plastid targeting signal.

Background: Large-scale computational prediction of protein structures represents a cost-effective alternative to empirical structure determination with particular promise for non-model organisms and neglected pathogens. Conventional sequence-based tools are insufficient to annotate the genomes of such divergent biological systems. Conversely, protein structure tolerates substantial variation in primary amino acid sequence, and is thus a robust indicator of biochemical function. Read More

Radical SAM-dependent adenosylation catalyzed by l-tyrosine lyases.

Org Biomol Chem 2018 Dec 6. Epub 2018 Dec 6.

Department of Chemistry, Fudan University, Shanghai 200433, China.

The radical S-adenosylmethionine (SAM) superfamily is currently the largest known enzyme family. These enzymes reductively cleave SAM to produce a highly reactive 5'-deoxyadenosyl (dAdo) radical, which abstracts a hydrogen from the substrate and initiates diverse reactions. The canonic dAdo radical-mediated hydrogen abstraction can be changed to radical addition reactions by using olefin-containing substrate analogues, which result in adenosylation reactions. Read More

The present study investigated the immunohistochemical expression of p53, p63, and p73 in different types of odontogenic cysts (OC), a group of common intraosseous jaw lesions, to provide a better understanding of p53-family functions in odontogenic lesions. We carried out immunohistochemical analysis to evaluate the expression of p53, p63, and p73 in 60 samples of OC, including dentigerous cysts, radicular cysts, orthokeratinized OC, and odontogenic keratocysts (OKC).
