Calreticulin regulates syncytialization through control of the synthesis and transportation of E-cadherin in BeWo cells.

Endocrinology 2018 Dec 14. Epub 2018 Dec 14.

Department of Obstetrics and Gynecology, Wakayama Medical University.

During placental development, mononuclear cytotrophoblasts differentiate and fuse to syncytiotrophoblasts (STB) to form syncytia, which secrete human chorionic gonadotropin (hCG). Decreased maternal perfusion of the placenta, which leads to placental dysfunction, induces changes in trophoblast syncytialization. Our previous study showed that calreticulin (CRT), a Ca2+-binding molecular chaperone found in the endoplasmic reticulum, is expressed in the human placenta and is involved in regulating extravillous trophoblast invasion, although its role in villous trophoblasts remains unclear.

CRISPR-C: circularization of genes and chromosome by CRISPR in human cells.

Nucleic Acids Res 2018 Dec;46(22):e131

Department of Biomedicine, Aarhus University, Denmark.

Extrachromosomal circular DNA (eccDNA) and ring chromosomes are genetic alterations found in humans with genetic disorders. However, there is a lack of genetic engineering tools to recapitulate and study the biogenesis of eccDNAs. Here, we created a dual-fluorescence biosensor cassette, which upon the delivery of pairs of CRISPR/Cas9 guide RNAs, CRISPR-C, allows us to study the biogenesis of a specific fluorophore expressing eccDNA in human cells.

Cytological and molecular aspects of the ageing sperm.

Hum Reprod 2018 Dec 14. Epub 2018 Dec 14.

Laboratory of Seminology - Sperm Bank 'Loredana Gandini' Department of Experimental Medicine, 'Sapienza' University of Rome, Italy.

Study Question: Is ageing associated with a decline in semen quality and molecular changes to human sperm?

Summary Answer: Semen quality declines with advancing age and characteristic molecular changes take place during the ageing process, including increased sperm DNA damage, altered sperm protamination and altered seminal plasma miRNA profile.

What Is Known Already: During ageing, the reproductive system is exposed to physiological changes and potentially damaging factors that may impair testicular function. Reactive oxygen species (ROS) can induce errors during DNA replication, transcription or post-transcriptional events (fragmentation, chromatin condensation abnormalities and protamine expression defects).

Effects of a single transient transfection of Ten-eleven translocation 1 catalytic domain on hepatocellular carcinoma.

PLoS One 2018 14;13(12):e0207139. Epub 2018 Dec 14.

College of Pharmacy, Nanchang University, Nanchang, Jiangxi, P.R. China.

Tumor suppressor genes (TSGs), including Ten-eleven translocation 1 (TET1), are hypermethylated in hepatocellular carcinoma (HCC). TET1 catalytic domain (TET1-CD) induces genome-wide DNA demethylation to activate TSGs, but so far, anticancer effects of TET1-CD are unclear. Here we showed that after HCC cells were transiently transfected with TET1-CD, the methylation levels of TSGs, namely APC, p16, RASSF1A, SOCS1 and TET1, were distinctly reduced, and their mRNA levels were significantly increased and HCC cells proliferation, migration and invasion were suppressed, but the methylation and mRNA levels of oncogenes, namely C-myc, Bmi1, EMS1, Kpna2 and c-fos, were not significantly change.

Research Update and Opportunity of Non-hormonal Male Contraception: Histone Demethylase KDM5B-Based Targeting.

Pharmacol Res 2018 Dec 11. Epub 2018 Dec 11.

Department of Animal Science & Technology and BET Research Institute, Chung-Ang University, Anseong, Gyeonggi-do, 17546, Republic of Korea. Electronic address:

With the continued increase in global human population, diverse contraception approaches have become increasingly essential, including non-hormonal male contraception. Non-hormonal approaches to contraception are very convenient; however, such options are limited because data regarding the identification and characterization of tissue/cell-specific targets and appropriate small molecule candidate contraceptives are lacking. Based on in-silico studies of genomics, transcriptomics, and proteomics, performed by mining datasets in PubMed, we first reviewed testis-, epididymis-, and germline cell-specific genes/proteins, with the aim of presenting evidence that many of these could become 'druggable' targets for the development of non-hormonal male contraceptives in the future.

Reducing the Complexity of Mathematical Models for the Plant Circadian Clock by Distributed Delays.

J Theor Biol 2018 Dec 11. Epub 2018 Dec 11.

Sainsbury Laboratory, University of Cambridge, Bateman Street, Cambridge, CB2 1LR, UK. Electronic address:

A major bottleneck in the modelling of biological networks is the parameter explosion problem - the exponential increase in the number of parameters that need to be optimised to data as the size of the model increases. Here, we address this problem in the context of the plant circadian clock by applying the method of distributed delays. We show that using this approach, the system architecture can be simplified efficiently - reducing the number of parameters - whilst still preserving the core mechanistic dynamics of the gene regulatory network.

The tubulin-associated unit (Tau) protein is an intrinsically disordered protein that plays a well-established role in promoting microtubule assembly and stabilization in neuronal axons at all stages of development. Identification of new interacting partners and different sub-cellular localizations of Tau in recent years led to the discovery of novel physiological functions in regulation of neuronal activity, neurogenesis, long-term depression, iron export and genomic integrity. In addition, Tau gene mutations, aberrant mRNA splicing and abnormal post-translational modifications, such as hyperphosphorylation, lead to formation of pathological, insoluble Tau aggregates that are a hallmark of neurodegenerative diseases, collectively known as tauopathies.

Mycobacterium tuberculosis (Mtb)-induced autophagy of alveolar macrophages has been confirmed to play a central role in the pathogenesis of tuberculosis. Growing evidence indicates that excessive or uncontrolled autophagic activity, which results in type II programmed cell death, can be regulated by many factors, including Wnt/β-catenin signalling. Wnt/β-catenin signalling has been demonstrated to be involved in multiple diseases through the regulation of autophagy; however, its exact role in regulating autophagy induced by Mtb remains unclear.

Neutrophils Restrict Tumor-Associated Microbiota to Reduce Growth and Invasion of Colon Tumors in Mice.

Gastroenterology 2018 Dec 11. Epub 2018 Dec 11.

Molecular & Integrative Physiology, University of Michigan School of Public Health, Ann Arbor MI; Internal Medicine Division of Gastroenterology, University of Michigan School of Public Health, Ann Arbor MI; Rogel Cancer Center. University of Michigan Medical School, Ann Arbor MI. Electronic address:

Background & Aims: Neutrophils are among the most prevalent immune cells in the microenvironment of colon tumors, are believed to promote growth of colon tumors, and their numbers correlate with outcomes of patients with colon cancer. Trials of inhibitors of neutrophil trafficking are under way in patients with cancer, but it is not clear how neutrophils contribute to colon tumorigenesis.

Methods: Colitis-associated colon cancer was induced mice with conditional deletion of neutrophils (LysMCre;Mcl1) and wild-type littermates (LysMCre;Mcl1, control mice) by administration of azoxythmethane and/or dextran sulfate sodium. Read More

West Nile virus epizootic in Germany, 2018.

Antiviral Res 2018 Dec 11. Epub 2018 Dec 11.

Friedrich-Loeffler-Institut, Federal Research Institute for Animal Health, Institute of Novel and Emerging Infectious Diseases, Greifswald-Insel Riems, Germany; German Centre for Infection Research (DZIF), Partner Site Hamburg-Luebeck-Borstel, Greifswald-Insel Riems, Germany. Electronic address:

The summer of 2018 in Germany was the second hottest and driest on record. These generally extremely favorable climatic conditions most likely triggered the further expansion and the efficient propagation of the zoonotic arthropod-borne West Nile virus in many Southern/Southeastern and even Central European countries. WNV infections were detected for the first time in resident wild and aviary birds, such as common blackbirds, northern goshawks and great grey owls in Eastern and Southeastern Germany. Read More

Organoid Modeling of the Tumor Immune Microenvironment.

Cell 2018 Dec;175(7):1972-1988.e16

Department of Medicine, Division of Hematology, Stanford University School of Medicine, Stanford, CA, USA. Electronic address:

In vitro cancer cultures, including three-dimensional organoids, typically contain exclusively neoplastic epithelium but require artificial reconstitution to recapitulate the tumor microenvironment (TME). The co-culture of primary tumor epithelia with endogenous, syngeneic tumor-infiltrating lymphocytes (TILs) as a cohesive unit has been particularly elusive. Here, an air-liquid interface (ALI) method propagated patient-derived organoids (PDOs) from >100 human biopsies or mouse tumors in syngeneic immunocompetent hosts as tumor epithelia with native embedded immune cells (T, B, NK, macrophages).
