Cellular mechanisms of odor detection in the olfactory system of the red flour beetle Tribolium castaneum
(2015-10-26)Olfaction, the detection of odors is pivotal for insects, since it leads them to food sources or mating partners and triggers important behaviors. For the detection of pheromones, CD36-related sensory neuron membrane ... -
Characterization of Small Conductance Ca2+-activated K+ Channel 2 Isoforms in Mouse Brain.
(2007-11-06)Small conductance calcium-activated potassium channels (SK channels) are potassium selective and voltage independent channels, which are activated by intracellular calcium during an action ... -
Characterization of the retinoic acid-induced gene network responsible for pancreas specification in Xenopus laevis
(2017-02-06)Retinoic acid (RA) is critically required for pancreas specification in Xenopus and other vertebrates. However, the gene network that is directly induced by RA-signaling in this context remains to be defined. We identified ... -
CHARGE syndrome: candidate genes and pathogenesis
(2015-09-25)CHARGE syndrome is a complex malformation syndrome affecting several organ systems like the central nervous system, ear, eye and heart. Heterozygous loss of function mutations in CHD7, a conserved chromatin remodelling ... -
Combining induced protease fragment assembly and microarray analysis to monitor signaling in living cells.
(2009-11-19)The ability to monitor multiple signaling events simultaneously in living cells is essential to better understand complex biological processes. So far, DNA-microarray technologies provide ... -
Development of methods to decrease aneuploidy in mammalian oocytes
(2022-05-24)Maternal mRNAs accompany and control all processes from the onset of meiosis until the blastocyst stage when the maternal pool of mRNAs is fully replaced by the emryonic mRNA set. The successful development of blastocysts ... -
Evaluation of genetic engineering and genome editing tools to develop multifactorial reproductive sterility or killing sperm systems for the improvement of the Sterile Insect Technique
(2020-11-20)Insects fulfill fundamental roles for the preservation of ecosystems such as pollination, but also represent key agricultural pests and human disease vectors accounting for immense economic losses and approximately one ... -
Function of the α/β-hydrolase fold family proteins Pummelig (CG1882) and Hormone-sensitive lipase in the Drosophila melanogaster lipid metabolism
(2016-09-30)To maintain energy homeostasis, all organisms need to adjust the generation and mobilization of their energy stores. The key molecules for energy storage are neutral lipids, mainly triacylglycerides (TAGs), which accumulate ... -
Functional analysis of the Drosophila gene smallish (CG43427)
(2013-09-18)The establishment and maintenance of cell polarity is crucial for the function of many cell types in multicellular organisms. Especially in epithelial tissues, cell polarity is connected to the regulation of cell adhesion ... -
Identification and analysis of JAK/STAT pathway target genes in Drosophila melanogaster
(2009-07-30)The JAK/STAT signalling cascade is one of the most conserved pathways in the animal kingdom. Aside from its developmental roles, the JAK/STAT pathway is needed for stem cell maintenance, ... -
MicroRNA-212/132 Family is Involved in the Regulation of Long-Term Spatial Memory and Synaptic Remodeling
(2014-10-30)MicroRNAs are noncoding transcripts with crucial functions in probably every organ system. The roles of miRNAs in neuronal processes and cognitive functions are recently being appreciated. The discovery of neuronal activity ... -
Molecular characterization and functional analysis of a novel long noncoding RNA in the mouse
(2019-05-24)Majority of mammalian transcriptomes encode long noncoding RNAs (lncRNAs) that are not translated into proteins. LncRNAs are mRNA-like transcripts that are longer than 200 nucleotides, transcribed by RNA-Pol-II and undergo ... -
Molecular correlates of spinal motor neuron functional specification and plasticity
(2013-07-30)The precision with which motor neurons connect to functionally matched muscle fibers ultimately determines the accuracy of behavioural outputs. Motor neurons are functionally diverse and can be subdivided into distinct ... -
Molecular mechanisms of germ cell specification and migration in Xenopus laevis
(2008-02-08)Vegetal localization of mRNA during Xenopus oogenesis is critical for future germ layers formation, embryonic patterning and germ line development. In frogs, a number of germ cells specific ... -
Novel roles of Celf1 and Tia1 during vegetal RNA localization in Xenopus laevis oocytes
(2015-10-29)The localization of certain mRNAs to the vegetal cortex of Xenopus oocytes is of crucial importance for germ cell development and germ layer formation of the future embryo. Vegetal RNA localization is mediated by signal ... -
Pancreatic β-Cell Regeneration in TIF-IA Knockout Mice
(2014-09-30)As the sole source of insulin production in body, pancreatic β-cells play an essential role in glucose homeostasis. Diabetes mellitus is a chronic disease characterized by loss, reduction, and/or malfunction of β-cell mass. ... -
Signalling of hematopoietic growth factors in mammalian neural cells
(2007-07-31)This dissertation examines signalling of hematopoietic growth factors in hippocampal neurons and cortical astrocytes. The activity patterns of Akt, ERK1/2 and Stat3 after treatment with ... -
