    Pheochromocytoma (PC12) Cell Response on Mechanobactericidal Titanium Surfaces.
    Materials (Basel) 2018 Apr 14;11(4). Epub 2018 Apr 14.
    School of Science, RMIT University, Melbourne, VIC 3001, Australia.
    Titanium is a biocompatible material that is frequently used for making implantable medical devices. Nanoengineering of the surface is the common method for increasing material biocompatibility, and while the nanostructured materials are well-known to represent attractive substrata for eukaryotic cells, very little information has been documented about the interaction between mammalian cells and bactericidal nanostructured surfaces. In this study, we investigated the effect of bactericidal titanium nanostructures on PC12 cell attachment and differentiation—a cell line which has become a widely used in vitro model to study neuronal differentiation.

    Surgical Approach to the Adrenal Glands.
    Eur Endocrinol 2015 Aug 19;11(2):98-99. Epub 2015 Aug 19.
    Consultant in Endocrine Surgery, Department of Endocrine Surgery, University Hospital of Wales, Cardiff, UK.
    Any surgeon treating a patient with adrenal disease should be a member of a multi-disciplinary team involving dedicated specialists, including an endocrinologist, anaesthetist, radiologist, intensivist and geneticist. In an era of epidemic numbers of adrenal incidentalomas, great care must be taken to determine not only the endocrine diagnosis, but also the benefits (if any) of adrenal surgery. Finally, the surgeon must be competent in both minimally invasive and gross resectional surgical techniques and know when to adopt these two very different surgical approaches. Read More

    Targeting NAD+/PARP DNA repair pathway as a novel therapeutic approach to SDHB-mutated cluster I pheochromocytoma and paraganglioma.
    Clin Cancer Res 2018 Apr 10. Epub 2018 Apr 10.
    Neuro-Oncology Branch, National Cancer Institute
    Purpose: Cluster I pheochromocytomas and paragangliomas (PCPGs) tend to develop malignant transformation, tumor recurrence, and multiplicity. Transcriptomic profiling suggests that cluster I PCPGs and other related tumors exhibit distinctive changes in the tricarboxylic acid (TCA) cycle, the hypoxia signaling pathway, mitochondrial electron transport chain, and methylation status, suggesting that therapeutic regimen might be optimized by targeting these signature molecular pathways.

    Experimental Design: In the present study, we investigated the molecular signatures in clinical specimens from cluster I PCPGs in comparison to cluster II PCPGs that are related to kinase signaling and often present as benign tumors. Read More

    Endocrinol Metab (Seoul) 2018 Mar;33(1):1-8
    Division of Endocrinology and Metabolism, Department of Internal Medicine, Asan Medical Center, University of Ulsan College of Medicine, Seoul, Korea.
    Secondary osteoporosis resulting from specific clinical disorders may be potentially reversible, and thus continuous efforts to find and adequately treat the secondary causes of skeletal fragility are critical to ameliorate fracture risk and to avoid unnecessary treatment with anti-osteoporotic drugs. Among the hyperfunctional adrenal masses, Cushing's syndrome, pheochromocytoma, and primary aldosteronism are receiving particularly great attention due to their high morbidity and mortality mainly by increasing cardiovascular risk. Interestingly, there is accumulating experimental and clinical evidence that adrenal hormones may have direct detrimental effects on bone metabolism as well. Read More

    Ndr2 Kinase Controls Neurite Outgrowth and Dendritic Branching Through α Integrin Expression.
    Front Mol Neurosci 2018 6;11:66. Epub 2018 Mar 6.
    Department of Genetics and Molecular Neurobiology, Institute of Biology, Otto-von-Guericke University Magdeburg, Magdeburg, Germany.
    The serine/threonine kinase Ndr2 has been shown to control the inside-out activation of the βsubunit of integrins and the formation of neurites in both primary neurons and neurally differentiated pheochromacytoma (PC12) cells. In this study, we demonstrate that Ndr2 kinase furthermore determines the substrate specificity of neurite extension in PC12 cells via expression of αβ integrins. We show that stable overexpression of Ndr2 in PC12 cells increases neurite growth and extension on poly-D-lysine substrate, likely involving an increased expression of active β integrin in the growth tips of these cells.
