651. New recordings of opisthobranch mollusks (Mollusca: Opisthobranchia) in the Slovenian portion of the Adriatic SeaLovrenc Lipej, Borut Mavrič, Sašo Moškon, 2012, drugi znanstveni članki Povzetek: Four opisthobranch species have been recorded in Slovenian coastal waters for the very first time: Tylodina perversa, Janolus cristatus, Eubranchus tricolor and Dicata odhneri. The first three were to some extent expected. D. odhneri was found on two occasions, representing new data on this rather rare and less known nudibranch species. The total number of recorded opisthobranch gastropod species is now 70.

652. Cancer chemopreventionAmr Amin, Metka Filipič, Su S. Chen, Regine Schneider-Stock, 2012, drugi znanstveni članki Povzetek: Cancers are characterized by the dysregulation of cell signaling pathways at multiple steps. Most current anticancer therapies however involve the modulation of a single target. The lack of safety and high cost of monotargeted therapies have encouraged alternative approaches. Both natural compounds, extracted from plants or animals, and synthetic compounds, derived from natural prototype structures, are now being used as cancer therapeutics and as chemopreventive compounds.

653. The ocean sampling day consortiumAnna Kopf, Valentina Turk, Tinkara Tinta, 2015, drugi znanstveni članki Povzetek: Ocean Sampling Day was initiated by the EU-funded Micro B3 (Marine Microbial Biodiversity, Bioinformatics, Biotechnology) project to obtain a snapshot of the marine microbial biodiversity and function of the world’s oceans. It is a simultaneous global mega-sequencing campaign aiming to generate the largest standardized microbial data set in a single day. This will be achievable only through the coordinated efforts of an Ocean Sampling Day Consortium, supportive partnerships and networks between sites. This commentary outlines the establishment, function and aims of the Consortium and describes our vision for a sustainable study of marine microbial communities and their embedded functional traits.

655. Range expansion of alien nudibranch Melibe viridis (Kelaart, 1858) in the northern Adriatic SeaLovrenc Lipej, Borut Mavrič, 2017, drugi znanstveni članki Povzetek: The alien nudibranch Melibe viridis (Kelaart, 1858) was recorded in the waters of Slovenia (Gulf of Trieste, northern Adriatic Sea). A specimen was photographed and fi lmed on rocky hard bottom of the Natural Monument Cape Madona in October 2016. This is the fi rst record of this large sized nudibranch for Slovenia and for the Gulf of Trieste, as well, and a new one among otherwise rare records on this species in the Adriatic Sea.

657. First record of the bryozoan Tricellaria inopinata (dʼHondt & Occhipinti Ambrogi, 1985) from the Slovenian seaAna Fortič, Borut Mavrič, 2018, drugi znanstveni članki Povzetek: In this paper we present the first record of Tricellaria inopinata d’Hondt & Occhipinti Ambrogi, 1985 for the Slovenian coastal sea. The colonies of this bryozoan were found attached to the mussel shells in the sight of Sečovlje, Strunjan and Debeli rtič mussel cultures from April to October 2018 and in Valdoltra harbour in November 2018. After the introduction into the Lagoon of Venice in the 1980s and its rapid spread throughout the lagoon in the following years, the species was regarded as an invasive taxon for that area and it is highly expected to colonize the whole Northern Adriatic region. The status of T. inopinata and its ecological impact has yet to be determined for the Slovenian coastal sea.

658. Occurrence of ribbon fish (Trachipterus trachypterus) In Slovenian waters (Northern Adriatic Sea)Lovrenc Lipej, Domen Trkov, Borut Mavrič, 2018, drugi znanstveni članki Povzetek: On 6th May 2018 a juvenile specimen of ribbon fish (Trachipterus trachypterus) was collected in shallow waters in Izola (Slovenia, northern Adriatic Sea). It measured 403 mm in total length and weighed 37.1 g. In stomach, fragments of seagrasses, pollen cones of pine, petals of terrestrial plant, fragments of terrestrial grass and beetles were found among food remains. The possible causes of this finding in Slovenian waters could be attributed to the ingression of southern Adriatic waters in its northern part. The specimen studied in this paper is the fifth record of this species in the Slovenian part of the Adriatic Sea. The cooperation between ichthyologists and fishermen proved to be crucial for the detection of the ribbon fish and other rare and less-known fish species, as well.

659. On the rare and less known shamefaced crab Calappa granulata (Brachyura, Calappidae) in the Northern Adriatic SeaNicola Bettoso, Marin Kirinčić, Borut Mavrič, Lovrenc Lipej, 2018, drugi znanstveni članki Povzetek: On 1st August 2016 and 23th July 2017 two specimens of the shamefaced crab Calappa granulata (Linnaeus, 1758) were caught in the northernmost area of the Adriatic Sea and represent the second and third offi cial record, respectively. More recently the records of this commercial species start to be no more unusual in this northern region. It is too early to express any reliable comment regarding whether or not this species established a breeding population in this area, however we could consider its northward extension as another consequence of global warming.

660. CXCR4 antagonists as stem cell mobilizers and therapy sensitizers for acute myeloid leukemia and glioblastoma?Vashendriya V. V. Hira, Cornelis J. F. van Noorden, Remco J. Molenaar, 2020, drugi znanstveni članki Povzetek: Glioblastoma is the most aggressive and malignant primary brain tumor in adults and has a poor patient survival of only 20 months after diagnosis. This poor patient survival is at least partly caused by glioblastoma stem cells (GSCs), which are slowly-dividing and therefore therapy-resistant. GSCs are localized in protective hypoxic peri-arteriolar niches where these aforementioned stemness properties are maintained. We previously showed that hypoxic peri-arteriolar GSC niches in human glioblastoma are functionally similar to hypoxic peri-arteriolar hematopoietic stem cell (HSC) niches in human bone marrow. GSCs and HSCs express the receptor C-X-C receptor type 4 (CXCR4), which binds to the chemoattractant stromal-derived factor-1α (SDF-1α), which is highly expressed in GSC niches in glioblastoma and HSC niches in bone marrow. This receptor–ligand interaction retains the GSCs/HSCs in their niches and thereby maintains their slowly-dividing state. In acute myeloid leukemia (AML), leukemic cells use the SDF-1α–CXCR4 interaction to migrate to HSC niches and become slowly-dividing and therapy-resistant leukemic stem cells (LSCs). In this communication, we aim to elucidate how disruption of the SDF-1α–CXCR4 interaction using the FDA-approved CXCR4 inhibitor plerixafor (AMD3100) may be used to force slowly-dividing cancer stem cells out of their niches in glioblastoma and AML. Ultimately, this strategy aims to induce GSC and LSC differentiation and their sensitization to therapy.
