Rotimer has an active role in the biofilm formation initiated by rotifers (e.g., Euchlanis dilatata or Adineta vaga) or in the female-male sexual interaction of monogononts. To understand the Ca2+- and polarity-dependent formation of this multifunctional viscoelastic material, it is essential to explore its molecular composition. The investigation of the rotifer-enhanced biofilm and Rotimer-inductor conglomerate (RIC) formation yielded several protein candidates to predict the Rotimer-specific main components. The exudate of E. dilatata males was primarily applied from different biopolimer-containing samples (biofilm or RIC). The advantage of males over females lies in their degenerated digestive system and simple anatomy. Thus, their exudate is less contaminated with food and endosymbiont elements. The sequenced and annotated genome and transcriptome of this species opened the way for identifying Rotimer proteins by mass spectrometry. The predicted rotifer-biopolymer forming components are SCO-spondins and 14-3-3 protein. The characteristics of Rotimer are similar to Reissner's fiber, which is found in the central nervous system of vertebrates and is mainly formed from SCO-spondins. This molecular information serves as a starting point for its interdisciplinary investigation and application in biotechnology, biomedicine, or neurodegeneration-related drug development.}, keywords = {IN-VIVO; PROTEINS; 14-3-3 PROTEIN; ANTIBODY; Biofilm; Ecotoxicology; Clearance; Chemistry, Applied; Biochemistry & Molecular Biology; Rotimer; SCO-spondin}, year = {2023}, eissn = {1879-0003}, orcid-numbers = {Datki, Zsolt László/0000-0002-2537-4741; Vedelek, Balázs/0000-0001-6981-0026; Sinka, Rita/0000-0003-4040-4184} } @article{MTMT:33084796, title = {Translational biomedicine-oriented exploratory research on bioactive rotifer-specific biopolymers}, url = {https://m2.mtmt.hu/api/publication/33084796}, author = {Datki, Zsolt László and Sinka, Rita}, doi = {10.17219/acem/152430}, journal-iso = {ADV CLIN EXP MED}, journal = {ADVANCES IN CLINICAL AND EXPERIMENTAL MEDICINE}, volume = {31}, unique-id = {33084796}, issn = {1899-5276}, year = {2022}, eissn = {2451-2680}, pages = {931-935}, orcid-numbers = {Datki, Zsolt László/0000-0002-2537-4741; Sinka, Rita/0000-0003-4040-4184} } @article{MTMT:32830008, title = {Particle-dependent reproduction and exogenic biopolymer secretion of protozoa co-cultured rotifers}, url = {https://m2.mtmt.hu/api/publication/32830008}, author = {Datki, Zsolt László and Sinka, Rita and Gálik, Bence and Galik-Olah, Zita}, doi = {10.1016/j.ijbiomac.2022.05.020}, journal-iso = {INT J BIOL MACROMOL}, journal = {INTERNATIONAL JOURNAL OF BIOLOGICAL MACROMOLECULES}, volume = {211}, unique-id = {32830008}, issn = {0141-8130}, year = {2022}, eissn = {1879-0003}, pages = {669-677}, orcid-numbers = {Datki, Zsolt László/0000-0002-2537-4741; Sinka, Rita/0000-0003-4040-4184} } @article{MTMT:32591465, title = {The interacting rotifer-biopolymers are anti- and disaggregating agents for human-type beta-amyloid in vitro}, url = {https://m2.mtmt.hu/api/publication/32591465}, author = {Datki, Zsolt László and Balázs, Evelin and Gálik, Bence and Sinka, Rita and Zeitler, Lavínia and Bozsó, Zsolt and Kálmán, János and Hortobágyi, Tibor and Oláh, Zita}, doi = {10.1016/j.ijbiomac.2021.12.184}, journal-iso = {INT J BIOL MACROMOL}, journal = {INTERNATIONAL JOURNAL OF BIOLOGICAL MACROMOLECULES}, volume = {201}, unique-id = {32591465}, issn = {0141-8130}, year = {2022}, eissn = {1879-0003}, pages = {262-269}, orcid-numbers = {Datki, Zsolt László/0000-0002-2537-4741; Sinka, Rita/0000-0003-4040-4184; Bozsó, Zsolt/0000-0002-5713-3096; Kálmán, János/0000-0001-5319-5639; Hortobágyi, Tibor/0000-0001-5732-7942; Oláh, Zita/0000-0002-6372-532X} } @article{MTMT:32129885, title = {Pszichoterápiás attitűdök áttekintése és követésének lehetőségei}, url = {https://m2.mtmt.hu/api/publication/32129885}, author = {Tóth, Erika Hajnalka and Kókai, Andrea and Kovács, Ildikó and Datki, Zsolt László and Andó, Bálint and Terenyi, Zoltán}, journal-iso = {PSYCHIATRIA HUNG}, journal = {PSYCHIATRIA HUNGARICA}, volume = {34}, unique-id = {32129885}, issn = {0237-7896}, year = {2021}, pages = {3-3}, orcid-numbers = {Kovács, Ildikó/0000-0003-4215-8351; Datki, Zsolt László/0000-0002-2537-4741} } @article{MTMT:32129874, title = {Rogersi hatótényezők biológiai-pszichofiziológiai paraméterekkel történő vizsgálatainak lehetőségei}, url = {https://m2.mtmt.hu/api/publication/32129874}, author = {Tóth, Erika Hajnalka and Kovács, Ildikó and Datki, Zsolt László and Andó, Bálint}, journal-iso = {PSYCHIATRIA HUNG}, journal = {PSYCHIATRIA HUNGARICA}, volume = {36}, unique-id = {32129874}, issn = {0237-7896}, year = {2021}, pages = {2-2}, orcid-numbers = {Kovács, Ildikó/0000-0003-4215-8351; Datki, Zsolt László/0000-0002-2537-4741} } @article{MTMT:32059771, title = {External modulation of Rotimer exudate secretion in monogonant rotifers}, url = {https://m2.mtmt.hu/api/publication/32059771}, author = {Balázs, Evelin and Oláh, Zita and Gálik, Bence and Somogyvári, Ferenc and Kálmán, János and Datki, Zsolt László}, doi = {10.1016/j.ecoenv.2021.112399}, journal-iso = {ECOTOX ENVIRON SAFE}, journal = {ECOTOXICOLOGY AND ENVIRONMENTAL SAFETY}, volume = {220}, unique-id = {32059771}, issn = {0147-6513}, abstract = {The Rotimer, a rotifer-specific biopolymer, is an exogenic bioactive exudate secreted by different monogonant species (e.g. Euchlanis dilatata or Lecane bulla). The production of this viscoelastic biomolecule is induced by different micro-particles, thereby forming a special Rotimer-Inductor Conglomerate (RIC) in a web format. In this case, the water insoluble Carmine crystals, filtered to size (max. diameter was 50 µm), functioned as an inductor. The RIC production is an adequate empirical indicator to follow up this filamentous biopolymer secretion experientially; moreover, this procedure is very sensitive to the environmental factors (temperature, pH, metals and possible natural pollutant agents). The above mentioned species show completely different reactions to these factors, except to the presence of calcium and to the modulating effects of different drugs. One of the novelties of this work is that the Rotimer secretion and consequently, the RIC-formation is a mutually obligatory and evolutionary calcium-dependent process in the concerned monogonants. This in vivo procedure needs calcium, both for the physiology of animals and for fiber formation, particularly in the latter case. The conglomerate covered area (%) and the detection of the longest filament (mm) of the given RIC were the generally and simultaneously applied methods in the current modulating experiments. Exploring the regulatory (e.g. calcium-dependency) and stimulating (e.g. Lucidril effect) possibilities of biopolymer secretion are the basis for optimizing the RIC-production capacities of these micro-metazoans.}, keywords = {biopolymer; exudate; Monogonant rotifer; Euchlanis dilatata; Ascorbic acid (PubChem CID: 54670067); CaCl(2) (PubChem CID: 24844); Carmine crystals (PubChem CID: 14950); Catechin (PubChem CID: 9064); Choline chloride (PubChem CID: 6209); DMSO (PubChem CID: 679); EDTA (PubChem CID: 6049); Ethyl nicotinate (PubChem CID: 69188); Glucose (PubChem CID: 5793); Glycerol (PubChem CID: 753); Isoguvacine (PubChem CID: 3765); KCl (PubChem CID: 4873); Lecane bulla; LiCl (PubChem CID: 23681138); Meclofenoxate hydrochloride (PubChem CID: 19379); MgCl(2) (PubChem CID: 24644); NaCl (PubChem CID: 5234); Rotimer; Selegiline (PubChem CID: 26757); Spermidine (PubChem CID: 1102); SrCl(2) (PubChem CID: 6101868); Taurine (PubChem CID: 1123); cAMP (PubChem CID: 6076)}, year = {2021}, eissn = {1090-2414}, orcid-numbers = {Oláh, Zita/0000-0002-6372-532X; Kálmán, János/0000-0001-5319-5639; Datki, Zsolt László/0000-0002-2537-4741} } @article{MTMT:31971856, title = {Detection of acute stress by smooth muscle electromyography: A translational study on rat and human}, url = {https://m2.mtmt.hu/api/publication/31971856}, author = {Pribék, Ildikó Katalin and Szűcs, Kálmán Ferenc and Süle, Miklós and Grosz, György and Ducza, Eszter and Vigh, Dóra and Tóth, Erika Hajnalka and Janka, Zoltán and Kálmán, János and Datki, Zsolt László and Gáspár, Róbert and Andó, Bálint}, doi = {10.1016/j.lfs.2021.119492}, journal-iso = {LIFE SCI}, journal = {LIFE SCIENCES}, volume = {277}, unique-id = {31971856}, issn = {0024-3205}, year = {2021}, eissn = {1879-0631}, orcid-numbers = {Kálmán, János/0000-0001-5319-5639; Datki, Zsolt László/0000-0002-2537-4741; Gáspár, Róbert/0000-0002-1571-7579} } @article{MTMT:31776926, title = {Exogenic production of bioactive filamentous biopolymer by monogonant rotifers}, url = {https://m2.mtmt.hu/api/publication/31776926}, author = {Datki, Zsolt László and Ács, Éva and Balázs, Evelin and Sovány, Tamás and Pannonhalminé Csóka, Ildikó and Zsuga, Katalin and Kálmán, János and Oláh, Zita}, doi = {10.1016/j.ecoenv.2020.111666}, journal-iso = {ECOTOX ENVIRON SAFE}, journal = {ECOTOXICOLOGY AND ENVIRONMENTAL SAFETY}, volume = {208}, unique-id = {31776926}, issn = {0147-6513}, abstract = {The chemical ecology of rotifers has been little studied. A yet unknown property is presented within some monogonant rotifers, namely the ability to produce an exogenic filamentous biopolymer, named ‘Rotimer’. This rotifer-specific viscoelastic fiber was observed in six different freshwater monogonants (Euchlanis dilatata, Lecane bulla, Lepadella patella, Itura aurita, Colurella adriatica and Trichocerca iernis) in exception of four species. Induction of Rotimer secretion can only be achieved by mechanically irritating rotifer ciliate with administering different types (yeast cell skeleton, denatured BSA, epoxy, Carmine or urea crystals and micro-cellulose) and sizes (approx. from 2.5 to 50 μm diameter) of inert particles, as inductors or visualization by adhering particles. The thickness of this Rotimer is 33 ± 3 nm, detected by scanning electron microscope. This material has two structural formations (fiber or gluelike) in nano dimension. The existence of the novel adherent natural product becomes visible by forming a ‘Rotimer-Inductor Conglomerate’ (RIC) web structure within a few minutes. The RIC-producing capacity of animals, depends on viability, is significantly modified according to physiological-(depletion), drug- (toxin or stimulator) and environmental (temperature, salt content and pH) effects. The E. dilatata-produced RIC is affected by protein disruptors but is resistant to several chemical influences and its Rotimer component has an overwhelming cell (algae, yeast and human neuroblastoma) motility inhibitory effect, associated with low toxicity.
