Nerve-less Sponge Has Clues To Nervous System Evolution
2012-06-18 15:25:18

UC Santa Barbara scientists turned to the simple sponge to find clues about the evolution of the complex nervous system and found that, but for a mechanism that coordinates the expression of genes that lead to the formation of neural synapses, sponges and the rest of the animal world may not be so distant after all. Their findings, titled "Functionalization of a protosynaptic gene expression network," are published in the Proceedings of the National Academy of Sciences. "If you're...

Researchers have discovered an added layer of complexity in the network that determines human embryonic stem cell fate. A report publishing online April 30th in the journal Cell, a Cell Press publication, shows that a microRNA known as miR-145 lowers the activity of three key ingredients in the "recipe" for making embryonic stem cells. The discovery may have implications for improving the efficiency of methods designed to reprogram differentiated cells into embryonic stem cell-like cells and...
