Molecular Studies on Head Development of the Amphipod Crustacean Parhyale hawaiensis
… beobachten lässt. In vielen Spezies sind optix/six3-Gene aktiv an der Kopf- und Gehirnentwicklung beteiligt, und zwar in einer Region, die anterior an die entsprechende otd-Expressionsdomäne angrenzt. Im Gegensatz dazu findet man während der regionalen Musterbildungsprozesse im Kopf …

Role of Xenopus Pitx3 during early development.
… expands the early expression domains of Pax6 and Six3 and alters development of the lens, optic vesicle, optic nerve, and diencephalon. Expression of a xPitx3/engrailed repressor chimera alters early expression domains of Pax6, Rx, and Six3, and later inhibits lens development consequently …

Functional analysis of embryonic brain development in Tribolium castaneum
… einzelne regulatorische Regionen der Gene Tc-six3 und Tc-rx gewählt, die in Kombination mit den Reportergenen tGFP und DsRedExpress, die Entwicklung bis hin zur vollständigen Struktur im larvalen Gehirn visualisierbar machen sollten. Die generierten transgenen Tiere wurden hinsichtlich der …

A Structural Study of Some (h6-Arene)ML2, First Row, Group VIII, Transition Metal Complexes and Their Derivatives
… evidence for discrete complexes containing Ni-SiX3 bonds is (h6-mesitylene)Ni(SiCl3)2 and presented. The compounds (h6-toluene)Ni(SiF3)2, crystallize in space group P21/c with Z = 2. The lattice constants at 23° C are: a = 9.056(2), b = 14.426(1), c = 13. 3 0 3 ( 2) ~, {J = 10 0. 6 9 ( 1 )0 , …

Head and protocerebral patterning in the spider Parasteatoda tepidariorum
… corresponded to the pre-cheliceral region: a six3- expressing anterior and otd2-expressing posterior cluster and one to the hh1-expressing pre- cheliceral/cheliceral boundary. This work provided new insights into pre-cheliceral patterning and supports conclusions made by Posnien et al. (2023), …

Identification and characterization of conserved regulatory elements by comparative genomics
… associated with two transcription factor genes, Six3 and Foxb1, were found to function as cis-regulatory elements by either enhancing or suppressing expression of the reporter gene in a tissue- and developmental-stage specific manner. The regulatory region of orexin (ORX) gene did not contain …

Suprachiasmatic nuclei development: A characterization of transcription factors and the influence of retinal innervation and VIP signaling
… deletion. We found that the well-conserved TF, Six3, is necessary for the initial formation and specification of SCN neurons, but not involved postmitotically in onset or localization of TF or peptide expression. This work begins to reveal aspects of the development of circadian function, by …

Funktion und Evolution von hochkonservierten Kopfgenen im Reismehlkäfer Tribolium castaneum
… Dabei zeigte sich, dass das Potential von six3 die Expression von wnt1 und pax6 zu reprimieren konserviert zu sein scheint. Der Vergleich der Expressionsdaten im Käfer und in Vertebraten zeigt, dass die Okkular/Preokkulare Region des embryonalen Insektenkopfes sehr viele Ähnlichkeiten zur …

The Identification and Characterization of Estrogen Receptors in the Mouse and Human Lens and Their Role in Cataract Development
… of ERdelta3 mice. The pax6, tcfap2a, tgfbeta2, six3, sox2, and pdgfalpha genes are known to have a critical role in lens development, proliferation, differentiation and maintenance of lens homeostasis. Therefore, future examination of these genes and their pathways in the lens may contribute to …
