Guiding non-neural, retinal pigment epithelium (RPE) to produce retinal neurons may offer a source of developing neurons for cell-replacement. Sox2 plays important roles in maintaining neural progenitor/stem cell properties and in converting fibroblasts into pluripotent stem cells. This study tests the possibility of using Sox2 to reprogram RPE to(More)
BACKGROUND High Salinity is a major environmental stress influencing growth and development of rice. Comparative proteomic analysis of hybrid rice shoot proteins from Shanyou 10 seedlings, a salt-tolerant hybrid variety, and Liangyoupeijiu seedlings, a salt-sensitive hybrid variety, was performed to identify new components involved in salt-stress signaling.(More)
The various cell types in the vertebrate retina arise from a pool of common progenitors. The way that the cell types are specified has been a long-standing issue. Decades of research have yielded a large body of information regarding the involvement of extrinsic factors, and only recently has the function of intrinsic factors begun to emerge.

The molecular mechanism of retinal ganglion cell (RGC) genesis and development is not well understood. Published data suggest that the process may involve two bHLH genes, ath5 and NSCL1. Gain-of-function studies show that ath5 increases RGC production in the developing retina. We examined whether two chick genes, cath5 and cNSCL1, can guide retinal pigment(More)
The molecular mechanism underlying vertebrate retinal development is not well understood. To examine whether neurogenin2 (ngn2) expression determines cell fate in the retina, we mapped the final fates of cells that once expressed ngn2, using the conditional, binary CreER -LacZ system. We found LacZ+ cells in all 3 nuclear layers of the mouse retina and(More)
Photoreceptors in the vertebrate retina are light-sensitive neurons, and their degeneration results in irreversible visual loss. Understanding how photoreceptor fate is determined is a prerequisite for developing photoreceptor replacement therapies. Previous studies identified two basic helix-loop-helix genes, neurogenin2 (ngn2) and neuroD, participating in(More)
Glioma stem-like cells (GSCs) may be the initiating cells in glioblastoma (GBM) and contribute to the resistance of these tumors to conventional therapies. Development of novel chemotherapeutic agents and treatment approaches against GBM, especially those specifically targeting GSCs are thus necessary. In the present study, we found that a novel Janus(More)
PURPOSE The genetic control of photoreceptor cell fate in the vertebrate retina is poorly understood. Published studies suggest that the genetic program underlying photoreceptor production involves neuroD, a proneural basic helix-loop-helix (bHLH) gene. The present study investigates whether neuroD is necessary for photoreceptor cell development, by using(More)
Ghrelin, a 28-amino-acid peptide, is mainly secreted by the stomach. Evidence has shown ghrelin to have neuroprotective effects. However, whether ghrelin protects hippocampal neurons against cell death in pilocarpine-induced seizures is unknown. We used Nissl staining to show that ghrelin attenuated the neuronal loss caused by pilocarpine-induced seizures(More)
