Sex determination is a rapidly evolving biological process controlled by differential gene expression. One family of transcription factors that initiate sex-specific gene expression and differentiation in many animal species are the Doublesex and Mab-3 (DM) domain proteins. While much is known about Doublesex-related proteins in various insect orders and commonly studied model systems, little is known

Cryptochromes (Cry) are ancient flavoproteins known to regulate circadian rhythms. In plants and some animals, Cry is sensitive to blue light due to its ability to bind the chromophore flavin adenine dinucleotide (FAD). Cry is also suggested to function in magnetoreception, since it can create light-dependent radical pairs with FAD that are sensitive to magnetic fields (Ritz2000; Liedvogel et al.,

Neuron navigator 2 (NAV2, RAINB1, POMFIL2, HELAD1, unc53H2) is essential for nervous system development. In the present study the spatial distribution of Nav2 transcript in mouse CNS during embryonic, postnatal and adult life is examined.

The current dogma of neural crest cell development suggests that there is a specific hierarchical gene regulatory

Proper cell-cell and cell-ECM interactions are vital for cell migration and patterning of the vertebrate embryo. MMPs and their inhibitors, RECK and TIMPs, are all differentially expressed during embryogenesis to regulate such ECM remodeling and cell interactions. MT1-MMP, RECK, and TIMP-2 are unique amongst other ECM-regulating proteins as they act in the pericellular space. Past studies have shown

Many aspects of the functional role of the E3 ubiquitin ligase Hectd1 in embryogenesis and in cell biology still remain to be elucidated. In order to contribute to this task we now report the generation of a new transgenic mouse model for Hectd1 using the gene trap strategy.

In the present study, both temporal and spatial expression patterns of fosl1 and fosl2 were examined

We exploited the high Ras activity induced differentiation of supernumerary R7 cells in Drosophila eyes to examine if hsrω lncRNAs influence active Ras signaling. Surprisingly, either down- or up-regulation of hsrω lncRNAs in sev-GAL4>RasV12 expressing eye discs resulted in complete pupal lethality and substantially greater increase in R7 photoreceptor number at the expense of cone cells. Enhanced

The founding member of the sirtuin family, yeast Sir2, was the first evolutionarily conserved gene to be identified as a regulator of longevity. Sirtuins constitute a protein family of metabolic sensors, translating changes in NAD + levels into adaptive responses, thereby acting as crucial regulators of the network that controls energy homeostasis and as such determines healthspan. In mammals the sirtuin

UNC119 proteins are required for ciliary trafficking in a process called lipidated protein intraflagellar targeting (LIFT) or through vesicle transport. However, although unc119 has been studied in a variety of contexts, either organismal constraints or genetic redundancy has largely restricted their study in ciliary contexts. One possible solution for this is to use the zebrafish, however, the unc119
