    University of Lille, Structural and Functional Glycobiology Unit, UMR CNRS 8576, Lille, France.
    Gangliosides are glycosphingolipids concentrated in glycolipid-enriched membrane microdomains. Mainly restricted to the nervous system in healthy adult, complex gangliosides such as GD3 and GD2 have been shown to be involved in aggressiveness and metastasis of neuro-ectoderm derived tumors such as melanoma and neuroblastoma. GD3 synthase (GD3S), the key enzyme that controls the biosynthesis of complex gangliosides, was shown to be over-expressed in Estrogen Receptor (ER)-negative breast cancer tumors, and associated with a decreased overall survival of patients.

    Melanosome-Targeting Near-Infrared Fluorescent Probe with Large Stokes Shift for in Situ Quantification of Tyrosinase Activity and Assessing Drugs Effects on Differently Invasive Melanoma Cells.
    Anal Chem 2018 Apr 26. Epub 2018 Apr 26.
    Tyrosinase (TYR) plays a vital role in melanin biosynthesis and is widely regarded as a relatively specific marker for melanocytic lesions which involve vitiligo, malignant cutaneous melanoma, Parkinson's disease (PD), etc. However, the detection of TYR in living cells with fluorescent probes is usually interfered by diverse endogenous reactive oxygen species (ROS) and reactive nitrogen species (RNS). Herein, we synthesized a melanosome-targeting near-infrared (NIR) fluorescent probe (HB-NP) with a large Stokes shift (195 nm), achieving a highly sensitive and selective in situ detection for intracellular TYR, by incorporating m-hydroxybenzy moiety that recognizes TYR specifically and the morpholine unit which facilitates the probe accumulating in melanosome into salicyladazine skeleton.

    The best of both worlds: a hybrid approach for optimal pre- and intraoperative identification of sentinel lymph nodes.
    Eur J Nucl Med Mol Imaging 2018 Apr 25. Epub 2018 Apr 25.
    Interventional Molecular Imaging Laboratory, Department of Radiology, Leiden University Medical Center, Albinusdreef 2 (C2-S zone), PO BOX 9600, 2300 RC, Leiden, The Netherlands.
    Purpose: Hybrid image-guided surgery technologies such as combined radio- and fluorescence-guidance are increasingly gaining interest, but their added value still needs to be proven. In order to evaluate if and how fluorescence-guidance can help realize improvements beyond the current state-of-the-art in sentinel node (SN) biopsy procedures, use of the hybrid tracer indocyanine green (ICG)-Tc-nancolloid was evaluated in a large cohort of patients.

    Patients And Methods: A prospective trial was conducted (n = 501 procedures) in a heterogeneous cohort of 495 patients with different malignancies (skin malignancies, oral cavity cancer, penile cancer, prostate cancer and vulva cancer). Read More

    Role of MDA5 and interferon-I in dendritic cells for T cell expansion by anti-tumor peptide vaccines in mice.
    Cancer Immunol Immunother 2018 Apr 25. Epub 2018 Apr 25.
    Cancer Immunology, Immunotherapy and Tolerance Program, Georgia Cancer Center, Augusta University, 1410 Laney Walker Blvd., CN-4121, Augusta, GA, 30912, USA.
    Cytotoxic T lymphocytes (CTLs) are effective components of the immune system capable of destroying tumor cells. Generation of CTLs using peptide vaccines is a practical approach to treat cancer. We have previously described a peptide vaccination strategy that generates vast numbers of endogenous tumor-reactive CTLs after two sequential immunizations (prime-boost) using poly-ICLC adjuvant, which stimulates endosomal toll-like receptor 3 (TLR3) and cytoplasmic melanoma differentiation antigen 5 (MDA5).

    Exploiting TERT dependency as a therapeutic strategy for NRAS-mutant melanoma.
    Oncogene 2018 Apr 26. Epub 2018 Apr 26.
    Molecular & Cellular Oncogenesis Program, The Wistar Institute, Philadelphia, PA, USA.
    Targeting RAS is one of the greatest challenges in cancer therapy. Oncogenic mutations in NRAS are present in over 25% of melanomas and patients whose tumors harbor NRAS mutations have limited therapeutic options and poor prognosis. Thus far, there are no clinical agents available to effectively target NRAS or any other RAS oncogene. Read More

    Oncolytic viruses as engineering platforms for combination immunotherapy.
    Nat Rev Cancer 2018 Apr 25. Epub 2018 Apr 25.
    Trev and Joyce Deeley Research Centre, British Columbia Cancer Agency, Victoria, British Columbia, Canada.
    To effectively build on the recent successes of immune checkpoint blockade, adoptive T cell therapy and cancer vaccines, it is critical to rationally design combination strategies that will increase and extend efficacy to a larger proportion of patients. For example, the combination of anti-cytotoxic T lymphocyte-associated antigen 4 (CTLA4) and anti-programmed cell death protein 1 (PD1) immune checkpoint inhibitors essentially doubles the response rate in certain patients with metastatic melanoma. However, given the heterogeneity of cancer, it seems likely that even more complex combinations of immunomodulatory agents may be required to obtain consistent, durable therapeutic responses against a broad spectrum of cancers.

    Nodal induced by hypoxia exposure contributes to dacarbazine resistance and the maintenance of stemness in melanoma cancer stem‑like cells.
    Oncol Rep 2018 Apr 23. Epub 2018 Apr 23.
    Department of Burns and Plastic Surgery Unit, West China Hospital of Sichuan University, Chengdu, Sichuan 610041, P.R. China.
    Nodal signaling has a critical role in the processes of embryogenesis and is necessary for maintaining cell stemness. However, its upregulation in melanoma is positively correlated with malignant potential, including cancer progression, metastasis and recurrence, and a recent report has revealed its role in promoting self‑renewal capacity in melanoma. Our study aimed to explore the effects of hypoxia exposure, which is one of the main causes of chemoresistance in melanoma, on the physiological processes of melanoma cancer stem‑like cells (CSCs) via regulating Nodal.

    Capping protein-controlled actin polymerization shapes lipid membranes.
    Nat Commun 2018 Apr 24;9(1):1630. Epub 2018 Apr 24.
    Lehrstuhl für Zellbiophysik, Technische Universität München, James-Franck-Str. 1, D-85748, Garching, Germany.
    Arp2/3 complex-mediated actin assembly at cell membranes drives the formation of protrusions or endocytic vesicles. To identify the mechanism by which different membrane deformations can be achieved, we reconstitute the basic membrane deformation modes of inward and outward bending in a confined geometry by encapsulating a minimal set of cytoskeletal proteins into giant unilamellar vesicles. Formation of membrane protrusions is favoured at low capping protein (CP) concentrations, whereas the formation of negatively bent domains is promoted at high CP concentrations. Read More

    No systematic reviews are available on data from humans on cancer risk from exposure to permethrin, a widely used insecticide for which some animal studies have reported positive findings based on mechanisms that may not be relevant to humans. We identified potentially relevant articles through a search of electronic databases which included all studies of pesticide exposure and human cancer. A total of 18 articles were selected, including six identified from the list of references of other articles. Read More

    Merkel cell carcinoma (MCC) is a rare but more lethal cutaneous cancer than melanoma. However, spontaneous regression of a number of MCC has been reported, although the cause of this regression remains unclear. In most cases, MCC regresses after a surgical procedure, for example, biopsy. Read More
