Through transancestry meta-analysis of genome-wide association studies of estimated glomerular filtration rate (eGFR) and independent replication (n = 1,046,070), we identified 264 associated loci (166 new). Of these,147 were likely to be relevant for kidney function on the basis of associations with the alternative kidney function marker blood urea nitrogen (n = 416,178). Pathway and enrichment analyses, including mouse models with renal phenotypes, support the kidney as the main target organ. A genetic risk score for lower eGFR was associated with clinically diagnosed CKD in 452,264 independent individuals. Colocalization analyses of associations with eGFR among 783,978 European-ancestry individuals and gene expression across 46 human tissues, including tubulo-interstitial and glomerular kidney compartments, identified 17 genes differentially expressed in kidney. Fine-mapping highlighted missense driver variants in 11 genes and kidney-specific regulatory variants. These results provide a comprehensive priority list of molecular targets for translational research.

Group CY - New York ER - TY - THES A1 - Schmidt, Ruth Maria T1 - Signalkaskaden und Steuermechanismen in den Speicheldrüsen von Dipteren T1 - Signalling pathways and control mechanisms in the salivary glands of Diptera N2 - Flüssigkeitssekretion und Proteinsekretion werden in Speicheldrüsen von Insekten über Hormone und Neurotransmitter gesteuert. Diese entfalten ihre physiologische Wirkung in den sekretorischen Drüsenzellen hauptsächlich über den zyklischen Adenosinmonophosphat (cAMP)-Signalweg und den Inositoltrisphosphat (IP3) / Ca2+-Signalweg. Die Mechanismen möglicher Wechselwirkungen zwischen diesen Signalwegen und ihre physiologischen Auswirkungen sind unzureichend bekannt. Im Mittelpunkt dieser Arbeit stand die Frage, ob und wie sich der Ca2+-Signalweg und der cAMP-Signalweg in der Speicheldrüse der Diptere Calliphora vicina beeinflussen. Substanzen wie 5-Fluoro-α-Methyltryptamin und Histamin wurden in früheren Arbei-ten als Agonisten genutzt, um in den Speicheldrüsen von C. vicina selektiv den cAMP-Signalweg (getrennt vom IP3/Ca2+-Signalweg) zu aktivieren. Es zeigte sich in transepithelialen Potentialmessungen und mikrofluorometrischen Ca2+-Untersuchungen, dass beide Substanzen sowohl den cAMP-Weg als auch den Ca2+-Signalweg aktivierten. Die physiologischen Ursachen der Histamin-induzierten Ca2+-Erhöhung wurden genauer untersucht. Zusammengefasst zeigten diese Untersuchungen, dass Histamin wie 5-HT den cAMP-Weg und die Phosphoinositidkaskade aktivierte. Im Gegensatz zu den 5-HT-induzierten Ca2+-Oszillationen, welche durch interzelluläre Ca2+-Wellen synchronisiert werden, verursachte Histamin bei niedrigen Konzentrationen lokale Ca2+-Oszillationen in einzelnen Zellen (keine Wellen). Bei höheren Histamin-Konzentrationen war eine anhaltende Ca2+-Erhöhung oder ein synchrones Ca2+-beating in der gesamten Drüse zu beobachten. Des Weiteren wurde die Frage untersucht, ob eine Erhöhung der intrazellulären cAMP-Konzentration den IP3 Ca2+-Signalweg in den Epithelzellen der Speicheldrüse beeinflussen kann. Es zeigte sich, dass cAMP den durch schwellennahe 5-HT-Konzentrationen induzierten Ca2+-Anstieg verstärkte. Diese Verstärkung wurde durch eine PKA-vermittelte Sensitivierung des IP3-Rezeptor/Ca2+-Kanals für IP3 verursacht. Immunzytochemische Untersuchungen deuten dar-auf hin, dass die Proteinkinase A eng mit dem IP3-Rezeptor/Ca2+-Kanal assoziiert ist. Diese Messungen zeigen erstmals, dass auch bei Invertebraten der Botenstoff cAMP, PKA-vermittelt, den IP3-Rezeptor/Ca2+-Kanal des ER für IP3 sensitiviert. N2 - Fluid- and protein-secretion in the salivary glands of insects are controlled by hormones or neurotransmitters. These agonists activate two signalling cascades: the cAMP-pathway and the IP>sub>3/Ca-pathway. The functional crosstalk between these two signalling pathways is poorly understood. Functional crosstalk between cAMP-pathway and IP3/Ca2+-pathway was investigated in the salivary glands of the blowfly, Calliphora vicina. Histamine and 5-alpha-methyltryptamine were used in an attempt to activate the cAMP-pathway selectively, as suggested previously. By using transepithelial potential-measurements and microfluorometric Ca2+-imaging it was demonstrated that both substances activate the cAMP- and the IP3/Ca2+-pathway. The physiological effects of histamine were investigated in detail. These experiments show that histamine causes an intracellular Ca2+-elevation that, in some preparations exhibits oscillations with concentration-dependent frequencies. In contrast to 5-HT induced intracellular Ca2+-oscillations and propagating intercellular Ca2+-waves histamine produces local Ca2+-oscillations in single cells or synchronous Ca2+-beating in the whole gland. In addition the effects of increasing cAMP on the IP3/Ca2+-pathway in the salivary glands of the blowfly were studied. It could be demonstrated that cAMP augments the 5-HT-induced Ca2+-increase in glands stimulated with low doses of 5-HT. This potentiation is the result of a PKA-mediated sensitisation of the IP3-receptor/Ca2+-channel for IP3. Results of immunocytochemical analyses show that the PKA is spatially associated with the ER. These results show for the first time that in invertebrates as well as in vertebrates the second messenger cAMP sensitises the IP3-receptor/Ca2+-channel for IP3 by the action of a PKA.
