Final results should help the understanding of the molecular physiology of Leydig cells in the stress response of the organism as a whole. Andric SA, Zivadinovic D, Gonzalez-Iglesias AE, Lachowitcz A, Tomic M & Stojilkovic SS (2005): Endothelin-induced long lasting and Ca2 influx-independent blockade of intrinsic secretion in pituitary cells by Gz subunits. LEADING OF PROJECTS • Reinforcement of Research Potential of the Laboratory for Ecotoxicology (Rep-Lecotox) Contract No.: INCO-CT-2006-043559-REP-LECOTOX, financed by the European Commission within The Sixth Framework Programme (FP6) of the European Union. Radmila Kovačević, Faculty of Sciences, Novi Sad Period: January 2007 – December 2009.
(2008) Cold hardening processes in the Antarctic springtail Cryptopygus antarcticus: Clues from a microarray, Journal of Insect Physiology, Vol. • Molecular physiology of Leydig cells in response to stress (APV0667) The project is co-funded by the Provincial Secretariat for Science and Technological Development of the AP Vojvodina. The results demonstrated the importance of the “cross-talk” communication between c AMP and c GMP signaling, as well as of mitochondrial dynamics and stereogenesis in the synchronization of the function of Leydig cells and development of an adaptive response. Kostic TS, Andric SA & Stojilkovic SS (2004): Receptor-controlled phosphorylation of a1 soluble guanylyl cyclase enchances nitric oxide-dependent cyclic guanosine 5’-monophosphate production in pituitary cells. All LECOTOX activities are carried out in accordance with the principles of good laboratory practice (GLP), observing ethical standards.

Results: defining of new regulation mechanisms of androgens production in normal and disturbed conditions of homeostasis of Leydig cells (hypogonadism, steroid-dependent cancers, as well as the other reproductive dysfunctions). The objective: to study the c AMP/c GMP signal paths of “cross-talk” communication as the possible mechanism of adaptation capable of contributing to a better recovery of the steroidogenesis of Leydig cells in the course of repeated immobilization stress. Andric SA, Gonzalez-Iglesias AE, Van-Goor F, Tomic M & Stojilkovic SS (2003): Nitric oxide inhibits prolactin secretion in pituitary cells downstream of voltage-gated calcium influx. LECOTOX is capable of performing aquatic tests for the needs of establishing standards of the quality of the environment (according to the Annex V of Water Framework Directive) and provide expertise to the pertinent organs and industry in the case of exploration monitoring.

The objective: to study the role of the NO-c GMP signal path in the regulation of steroidogenesis in Leydig cells and the mechanism of the action of this signal path with normal, stressed, hypogonadal/testosteron treated, and Viagra-treated rats. Kostic TS, Andric SA, Tomic M & Stojilkovic SS (2002): Calcium-independent and c AMP-dependent modulation of soluble guanylyl cyclase activity by G-protein coupled receptors in pituitary cells. The battery of acute and chronic toxicology tests on standard test species includes: Daphnia magna, Danio rerio, Selenastrum capricornutum, Vibrio fischeri, Pseudomonas putida according to ISO/CEN, OECD and US EPA standard methods for testing toxicity of pure substances and complex mixtures; tests of ambiental toxicity and whole effluent toxicity (WET) of water for the purpose of monitoring in accordance with the current legislation, but also the tests of toxic contaminated sediment and soils for the needs of study- Instructing how to use the instrument for quantitative gene expression analysis 20 Department of Biology and Ecology Cooperation • Department of Effect-Directed Analysis and Department of Bioanalytical Ecotoxicology, Helmholtz Centre for Environmental Research (UFZ), Leipzig, Germany, • Molecular Pathobiology - Cell Toxicology, School of Biosciences, University of Birmingham, Birmingham, UK, • RECETOX, Masaryk University, Brno, Czech Republic, • CECRA, Department of Chemistry, Faculty of Sciences, University of Novi Sad Work in the lab for cell cultures ing feasibility of proposed remediation programs and risk assessment.
