چکیده
The plane of division of granule neuron progenitors (GNPs) was analysed with respect to the pial surface in P0 to P14 cerebellum and the results showed that there was a significant bias towards the plane of cell division being parallel to pial surface across this developmental window. In addition, the distribution of β-Catenin in anaphase cells was analysed, which showed that there was a significant asymmetry in the distribution of β-Catenin in dividing GNPs. Further, inhibition of Sonic Hedgehog (Shh) signalling had an effect on plane of cell division. Asymmetric distribution of β-Catenin was shown to occur towards the source of a localized extracellular cue.

متن کاملDistribution of the glutamine synthetase isozyme GSp1 in maize (Zea mays).
In maize (Zea mays L.), GSp1, the predominant GS isozyme of the developing kernel, is abundant in the pedicel and pericarp, but absent from the endosperm and embryo. Determinations of GSp1 tissue distribution in vegetative tissues have been limited thus far to root and leaves, where the isozyme is absent. However, the promoter from the gene encoding GSp1 has been shown to drive reporter gene ex...
متن کاملAcidic phospholipids are required during solubilization of amino acid transport systems of Lactococcus lactis.
The branched-chain amino acid transport system of Lactococcus lactis was solubilized with n-octyl beta-D-gluco-pyranoside and reconstituted into proteoliposomes. Transport activity was recovered only when solubilization was performed in the presence of acidic phospholipids. Omission of acidic phospholipids during solubilization resulted in an inactive transport protein and the activity could no...
متن کاملNpgRj_NN_1479 865..872
Adult neurogenesis in mammals is restricted to two small regions, including the olfactory bulb, where GABAergic and dopaminergic interneurons are newly generated throughout the entire lifespan. However, the mechanisms directing them towards a specific neuronal phenotype are not yet understood. Here, we demonstrate the dual role of the transcription factor Pax6 in generating neuronal progenitors...
