Hedgehog signaling has been linked to cell proliferation in a variety of systems; however, its effects on the cycle have not closely studied. In vertebrate retina, Hedgehog's are controversial, with some reports emphasizing increased and others pointing role exit. Here we demonstrate novel for speeding up developing retina by reducing length G1 G2 phases. These fast cycling cells tend exit early. Conversely, retinal progenitors blocked more slowly, longer phases, remain longer. may modulate...
Progenitor cells in the central nervous system must leave cell cycle to become neurons and glia, but signals that coordinate this transition remain largely unknown. We previously found Wnt signaling, acting through Sox2, promotes neural competence Xenopus retina by activating proneural gene expression. now report Sox2 inhibit differentiation Notch activation. Independently of stimulates retinal progenitor proliferation this, when combined with block on differentiation, maintains fates....
Protein Secondary Structure Prediction (PSSP) is regarded as a challenging task in bioinformatics, and numerous approaches to achieve more accurate prediction have been proposed. Accurate PSSP can be instrumental inferring protein tertiary structure their functions. Machine Learning particular Deep show promising results for the problem.
