Novel methods in adrenal research: a metabolomics approach.

Histochem Cell Biol 2019 Feb 6. Epub 2019 Feb 6.

Research Unit Analytical Pathology, Helmholtz Zentrum München, German Research Center for Environmental Health (GmbH), Neuherberg, Germany.

Metabolic alterations have implications in a spectrum of tissue functions and disease. Aided by novel molecular biological and computational tools, our understanding of physiological and pathological processes underpinning endocrine and endocrine-related disease has significantly expanded over the last decade. Herein, we focus on novel metabolomics-related methodologies in adrenal research: in situ metabolomics by mass spectrometry imaging, steroid metabolomics by gas and liquid chromatography-mass spectrometry, energy pathway metabologenomics by liquid chromatography-mass spectrometry-based metabolomics of Krebs cycle intermediates, and cellular reprogramming to generate functional steroidogenic cells and hence to modulate the steroid metabolome.

Region-specific changes in brain kisspeptin receptor expression during estrogen depletion and the estrous cycle.

Histochem Cell Biol 2019 Jan 22. Epub 2019 Jan 22.

Department of Anatomy and Neurobiology, Graduate School of Medicine, Nippon Medical School, Sendagi 1-1-5, Bunkyo-ku, Tokyo, 113-8602, Japan.

Kisspeptin acts as a potent neuropeptide regulator of reproduction through modulation of the hypothalamic-pituitary-gonadal axis. Previous studies revealed sex differences in brain expression patterns as well as regulation of expression by estrogen. Alternatively, sex differences and estrogen regulation of the kisspeptin receptor (encoded by Kiss1r) have not been examined at cellular resolution. Read More

Characterization of blood-brain barrier integrity in a B-cell-dependent mouse model of multiple sclerosis.

Histochem Cell Biol 2019 Jan 21. Epub 2019 Jan 21.

Department of Anatomy and Cell Biology, University of Würzburg, Würzburg, Germany.

Recent studies with B-cell-depleting antibodies have demonstrated clinical success in the treatment of multiple sclerosis (MS) patients. While these antibodies efficiently target B cells in the blood, it is unclear how effective they are in the central nervous system (CNS), especially in the context of limited blood-brain barrier (BBB) permeability and the ongoing discussion on the relevance of B-cell aggregate formation in the brains of SP-MS patients. The aim of this study was to evaluate BBB integrity in the context of B-cell-dependent neuroinflammation in a mouse model of MS. Read More

An update on the Golgi staining technique improving cerebellar cell type specificity.

Histochem Cell Biol 2019 Jan 3. Epub 2019 Jan 3.

Institute of Anatomy, Anatomy and Cell Biology, University of Bonn, Nussallee 10, 53115, Bonn, Germany.

The detailed morphological characterization of single cells was a major breakthrough in neuroscience during the turn of the twentieth century, enabling Ramon y Cajal to postulate the neuron doctrine. Even after 150 years, single cell analysis is an intriguing goal, newly motivated by the finding that autism might be caused by intricate and discreet changes in cerebellar morphology. Besides new single labelling technologies, the Golgi staining technique is still in use due to its whole cell labelling characteristics, its superior contrast performance over other methods and its apparent randomness of staining cells within a whole tissue block.

Coping with formalin banning in pathology: under vacuum long-term tissue storage with no added formalin.

Histochem Cell Biol 2019 Jan 2. Epub 2019 Jan 2.

Anatomic Pathology, Department of Surgical Sciences and Integrated Diagnostics (DISC), University of Genoa, via De Toni 14, 16132, Genoa, Italy.

Formalin is toxic and has recently been classified as carcinogenic leading to a proposed European formalin ban. But, the pathology use of formalin has however been completely overlooked, and this is proving to be a relevant issue, as no alternative, reliable, tissue fixative is available. Various systems have been proposed to reduce formalin use and exposure; long-term storage and disposal of formalin is also a problem. Read More

Differential expression of PKCα and -β in the zebrafish retina.

Histochem Cell Biol 2019 Jan 2. Epub 2019 Jan 2.

Institute of Molecular Life Sciences, University of Zurich, Winterthurerstrasse 190, 8057, Zurich, Switzerland.

The retina is a complex neural circuit, which processes and transmits visual information from light perceiving photoreceptors to projecting retinal ganglion cells. Much of the computational power of the retina rests on signal integrating interneurons, such as bipolar cells. Commercially available antibodies against bovine and human conventional protein kinase C (PKC) α and -β are frequently used as markers for retinal ON-bipolar cells in different species, despite the fact that it is not known which bipolar cell subtype(s) they actually label.

α-Parvin and β-parvin in the rat uterus during decidualisation and uterine receptivity.

Histochem Cell Biol 2018 Dec 5. Epub 2018 Dec 5.

Cell and Reproductive Biology Lab, Discipline of Anatomy and Histology, School of Medical Sciences, University of Sydney, Camperdown, Australia.

During early pregnancy, the uterine luminal epithelial cells (UECs) and endometrial stromal cells (ESCs) undergo morphological changes to enable blastocyst implantation. The present study investigates, for the first time, the cytoskeletal-associated proteins and α-actinin superfamily members, α-parvin and β-parvin, during early pregnancy in the rat uterus. These two PARVA proteins are involved in cell adhesion, morphological changes and regulation of other cytoskeletal proteins, through binding with proteins such as actin and integrin-linked kinase.

Histone deacetylase inhibitors suppress transdifferentiation of gonadotrophs to prolactin cells and proliferation of prolactin cells induced by diethylstilbestrol in male mouse pituitary.

Histochem Cell Biol 2018 Dec 3. Epub 2018 Dec 3.

Department of Histology and Cell Biology, Nagasaki University Graduate School of Biomedical Sciences, 1-12-4 Sakamoto, Nagasaki, 852-8523, Japan.

Diethylstilbestrol (DES), an estrogen agonist, increases prolactin (PRL) cells through transdifferentiation of follicle-stimulating hormone (FSH) and luteinizing hormone (LH) cells to PRL cells as well as proliferation of PRL cells in adult male mouse pituitary. Since hyperacetylation of histone H3 is implicated in the regulation of activation of various genes, we examined the effect of DES on the state of histone H3 acetylation. DES significantly reduced the immunohistochemical signal for acetylated histone H3 at lysine 9 (H3K9ac) in PRL, LH and FSH cells, but not for H3K18ac or H3K23ac. Read More

Detection of herpesvirus capsids in transmission electron microscopy images using transfer learning.

Histochem Cell Biol 2019 Feb 28;151(2):101-114. Epub 2018 Nov 28.

Central Facility for Electron Microscopy, Ulm University, Ulm, Germany.

The detailed analysis of secondary envelopment of the Human betaherpesvirus 5/human cytomegalovirus (HCMV) from transmission electron microscopy (TEM) images is an important step towards understanding the mechanisms underlying the formation of infectious virions. As a step towards a software-based quantification of different stages of HCMV virion morphogenesis in TEM, we developed a transfer learning approach based on convolutional neural networks (CNNs) that automatically detects HCMV nucleocapsids in TEM images. In contrast to existing image analysis techniques that require time-consuming manual definition of structural features, our method automatically learns discriminative features from raw images without the need for extensive pre-processing.

How high resolution 3-dimensional imaging changes our understanding of postnatal lung development.

Histochem Cell Biol 2018 Dec 2;150(6):677-691. Epub 2018 Nov 2.

Institute of Anatomy, University of Bern, Baltzerstrasse 2, 3012, Bern, Switzerland.

During the last 10 + years biologically and clinically significant questions about postnatal lung development could be answered due to the application of modern cutting-edge microscopic and quantitative histological techniques. These are in particular synchrotron radiation based X-ray tomographic microscopy (SRXTM), but also Helium Magnetic Resonance Imaging, as well as the stereological estimation of the number of alveoli and the length of the free septal edge. First, the most important new finding may be the following: alveolarization of the lung does not cease after the maturation of the alveolar microvasculature but continues until young adulthood and, even more important, maybe reactivated lifelong if needed to rescue structural damages of the lungs.

The role of autophagy in morphogenesis and stem cell maintenance.

Histochem Cell Biol 2018 Dec 31;150(6):721-732. Epub 2018 Oct 31.

Department of Anatomy and Molecular Embryology, Institute of Anatomy, Ruhr University Bochum, Universitätsstrasse 150, 44801, Bochum, Germany.

During embryonic development, cells need to undergo a number of morphological changes that are decisive for the shaping of the embryo's body, initiating organogenesis and differentiation into functional tissues. These remodeling processes are accompanied by profound changes in the cell membrane, the cytoskeleton, organelles, and extracellular matrix composition. While considerably detailed insight into the role of autophagy in stem cells biology has been gained in the recent years, information regarding the participation of autophagy in morphogenetic processes is only sparse.

Moonlighting nuclear pore proteins: tissue-specific nucleoporin function in health and disease.

Histochem Cell Biol 2018 Dec 25;150(6):593-605. Epub 2018 Oct 25.

Institute of Molecular Biology and Medicine, Université Libre de Bruxelles, Rue Profs. Jeener et Brachet 12, 6041, Gosselies, Belgium.

The nuclear pore complex is the main transportation hub for exchange between the cytoplasm and the nucleus. It is built from nucleoporins that form distinct subcomplexes to establish this huge protein complex in the nuclear envelope. Malfunctioning of nucleoporins is well known in human malignancies, such as gene fusions of NUP214 and NUP98 in hematological neoplasms and overexpression of NUP88 in a variety of human cancers.

Diversity of enteroendocrine cells investigated at cellular and subcellular levels: the need for a new classification scheme.

Histochem Cell Biol 2018 Dec 24;150(6):693-702. Epub 2018 Oct 24.

Department of Anatomy and Neuroscience, University of Melbourne, Parkville, VIC, 3010, Australia.

Enteroendocrine cells were historically classified by a letter code, each linked to a single hormone, deduced to be the only hormone produced by the cell. One type, the L cell, was recognised to store and secrete two products, peptide YY (PYY) and glucagon-related peptides. Many other exceptions to the one-cell one-hormone classifications have been reported over the last 40 years or so, and yet the one-hormone dogma has persisted. Read More

Serum affects keratinization and tight junctions in three-dimensional cultures of the mouse keratinocyte cell line COCA through retinoic acid receptor-mediated signaling.

Histochem Cell Biol 2018 Oct 17. Epub 2018 Oct 17.

Department of Morphological Biology, Fukuoka Dental College, 2-15-1 Tamura, Sawara-ku, Fukuoka, 814-0193, Japan.

Vitamin A, which is found in serum, is known to affect keratinocyte proliferation, epidermal differentiation, and keratinization. In mice, stratified epithelia in the oral cavity, esophagus, and forestomach are keratinized; however, these epithelia are not keratinized in humans. Several studies have reported that three-dimensional (3D) cultures of human keratinocytes in serum-containing medium could form keratinized epithelia. Read More

Morphological and molecular criteria allow the identification of putative germ stem cells in a lophotrochozoan, the Pacific oyster Crassostrea gigas.

Histochem Cell Biol 2018 Oct 15. Epub 2018 Oct 15.

Normandy University, Caen, France.

While our knowledge of bivalve gametogenesis recently progressed, data on early stages of gametogenesis remain to be developed, especially when dealing with germinal stem cells (GSC) and their niche in these organisms. Here, we wish to develop a strategy to identify putative GSC in Pacific oyster Crassostrea gigas based on morphological criteria combined with vasa marker expression. A histological quantitative approach, based on stereology, allowed us to identify two types of early germ cells in the germinal epithelium, one presenting round nuclei and the other irregular ones.

Versican silencing in BeWo cells and its implication in gestational trophoblastic diseases.

Histochem Cell Biol 2018 Oct 8. Epub 2018 Oct 8.

Cell Biology Laboratory, Institute of Health and Biological Sciences, Federal University of Alagoas, Campus A.C. Simões. Av. Lourival Melo Mota, s/n, 57072-970, Maceio, Alagoas, Brazil.

Versican is a proteoglycan known to interact with cells to influence their ability to proliferate, differentiate, migrate, invade and assemble extracellular matrix, with all of these cell functions present during placentation. In the placenta, cytotrophoblast cells have the ability to differentiate into the syncytiotrophoblast, a mechanism that is greatly increased in gestational trophoblastic diseases (GTD). Nevertheless, the molecular signaling underlying the increased syncytiotrophoblast differentiation are still being unveiled and may result in novel therapeutic targets for GTD. Read More

Anisomycin, a JNK and p38 activator, suppresses cell-cell junction formation in 2D cultures of K38 mouse keratinocyte cells and reduces claudin-7 expression, with an increase of paracellular permeability in 3D cultures.

Histochem Cell Biol 2018 Oct 4. Epub 2018 Oct 4.

Department of Morphological Biology, Fukuoka Dental College, 2-15-1 Tamura, Sawara-ku, Fukuoka, 814-0193, Japan.

Keratinocytes in the oral mucosal epithelium, which is a non-keratinized stratified epithelium, are exposed to various stimuli from the oral cavity. JNK and p38 are stress-activated mitogen-activated protein kinases (MAPKs) that are phosphorylated by various stimuli and are involved in the assembly and disassembly of tight junctions (TJs) in keratinocytes. Therefore, we investigated the effects of stress-activated MAPKs on TJs in a mouse keratinocyte cell line during cell-cell junction formation in two-dimensional (2D) cultures or stratification to form non-keratinized epithelium in 3D cultures.

Dynamics of WNT signaling components in the human ovary from development to adulthood.

Histochem Cell Biol 2019 Feb 4;151(2):115-123. Epub 2018 Oct 4.

Laboratory for Aging and Infertility Research, Department of Biology, Northeastern University, Boston, MA, 02115, USA.

WNT signaling has been shown to play a pivotal role in mammalian gonad development and sex differentiation; however, its role in the developing human ovary has not been investigated. We analyzed a quantitative mass spectrometry dataset to determine the expression of WNT signaling components between 47 and 137 days of development and in adult ovarian cortex tissue. WNT signaling was identified within the top ten canonical pathways of proteins detected at every developmental stage examined. Read More

Air-blood barrier thickening and alterations of alveolar epithelial type 2 cells in mouse lungs with disrupted hepcidin/ferroportin regulatory system.

Histochem Cell Biol 2018 Oct 3. Epub 2018 Oct 3.

Department of Pediatric Hematology, Oncology and Immunology, University of Heidelberg, Heidelberg, Germany.

Iron accumulates in the lungs of patients with common respiratory diseases or transfusion-dependent beta-thalassemia. Based on our previous work, we hypothesized that systemic iron overload affects the alveolar region of the lung and in particular the surfactant producing alveolar epithelial type II (AE2) cells. Mice with a point mutation in the iron exporter ferroportin, a model for human hemochromatosis type 4 were compared to wildtype mice (n = 5 each). Read More

Gephyrin: a key regulatory protein of inhibitory synapses and beyond.

Histochem Cell Biol 2018 Nov 27;150(5):489-508. Epub 2018 Sep 27.

Department of Medical Cell Biology, Institute for Anatomy and Cell Biology, Heidelberg University, Heidelberg, Germany.

Scaffolding proteins underlying postsynaptic membrane specializations are important structural and functional components of both excitatory and inhibitory synapses. At inhibitory synapses, gephyrin was identified as anchoring protein. Gephyrin self-assembles into a complex flat submembranous lattice that slows the lateral mobility of glycine and GABA receptors, thus allowing for their clustering at postsynaptic sites. Read More

Living Systems Institute, School of Biosciences, College of Life and Environmental Science, University of Exeter, Exeter, EX4 4QD, UK.

Cells of multicellular organisms are in continuous conversation with the neighbouring cells. The sender cells signal the receiver cells to influence their behaviour in transport, metabolism, motility, division, and growth. How cells communicate with each other can be categorized by biochemical signalling processes, which can be characterised by the distance between the sender cell and the receiver cell. Read More

Changes in ephrin gene expression during bone healing identify a restricted repertoire of ephrins mediating fracture repair.

Histochem Cell Biol 2019 Jan 24;151(1):43-55. Epub 2018 Sep 24.

Musculoskeletal Disease Center, Research Service (151), Jerry L. Pettis Memorial Veterans Administration Medical Center, 11201 Benton Street, Loma Linda, CA, 92357, USA.

To identify the repertoire of ephrin genes that might regulate endochondral bone fracture repair, we examined changes in ephrin ligand and receptor (Eph) gene expression in fracture callus tissues during bone fracture healing. Ephrin and Eph proteins were then localized in the fracture callus tissues present when changes in gene expression were observed. Ephrin gene expression was widespread in fracture tissues, but the repertoire of ephrin genes with significant changes in expression that might suggest a regulatory role in fracture callus development was restricted to the ephrin A family members Epha4, Epha5 and the ephrin B family member Efnb1.

Monoamines in the enteric nervous system.

Histochem Cell Biol 2018 Dec 24;150(6):703-709. Epub 2018 Sep 24.

Institute of Anatomy, Friedrich-Alexander-University Erlangen-Nürnberg, Krankenhausstraße 9, 91054, Erlangen, Germany.

Recent advances in neurogastroenterology have extended and refined our knowledge on the roles monoamines play in physiology and pathophysiology of the gastrointestinal tract. The catecholamine noradrenaline, as the primary transmitter of postganglionic sympathetic neurons, orchestrates motility and secretory reflexes and controls arterial perfusion as well as immune functions. The catecholamine dopamine is produced by a subpopulation of enteric neurons which possibly use it as transmitter. Read More

Institute of Molecular Health Sciences, ETH Zurich, Otto-Stern-Weg 7, HPL H16, 8093, Zurich, Switzerland.

Peroxisomes are ubiquitous and highly dynamic organelles that play a central role in the metabolism of lipids and reactive oxygen species. The importance of peroxisomal metabolism is illustrated by severe peroxisome biogenesis disorders in which functional peroxisomes are absent or disorders caused by single peroxisomal enzyme deficiencies. These multisystemic diseases manifest specific clinical and biochemical disturbances that originate from the affected peroxisomal pathways. Read More

Blank spots on the map: some current questions on nuclear organization and genome architecture.

Histochem Cell Biol 2018 Dec 20;150(6):579-592. Epub 2018 Sep 20.

National Cancer Institute, NIH, Bethesda, MD, 20892, USA.

The past decades have provided remarkable insights into how the eukaryotic cell nucleus and the genome within it are organized. The combined use of imaging, biochemistry and molecular biology approaches has revealed several basic principles of nuclear architecture and function, including the existence of chromatin domains of various sizes, the presence of a large number of non-membranous intranuclear bodies, non-random positioning of genes and chromosomes in 3D space, and a prominent role of the nuclear lamina in organizing genomes. Despite this tremendous progress in elucidating the biological properties of the cell nucleus, many questions remain. Read More
