Researchers Uncover Key Step In Manufacture of Memory Protein

...ade inside the endoplasmic reticulum, a convoluted network of tubes and channels inside the cell. The proBDNF winds through the endoplasmic reticulum until it reaches another structure within the cell, the golgi apparatus. There, the proBDNF binds to CPE, which protrudes from special rafts of fatty, choleste...

Examination of internal 'wiring' of yeast, worm, and fly reveals conserved circuits

...on. In contrast, the team did not find in yeast a network they found in both worm and fly that is involved in the guidance of nerve cell axons to their synaptic targets, or junctions, with other nerve cells. The process, considered an initial step in the development of the central nervous system, would not ...

...todes to humans. Central players in the regulatory network are the nuclear hormone receptors (NHRs), which are transcription factors that turn on or off a set of target genes when bound by specific lipid molecules. In the premier open-access journal PLoS Biology, Keith Yamamoto and colleagues show that the n...

Chemists identify key gene in development of type 1 diabetes

Programmable cells: Engineer turns bacteria into living computers

...out synthetic biology is that because we built the network from scratch, we should be able to model all the important details," he said. At some point in the future, he said, scientists will be able to choose a behavior they want from cells, and a computer program will create a genetic circuit to accomplish ...

Researchers devise way to mass-produce embryonic stem cells

...f cells. In preliminary work, Ouyang has created a network of neurons from undifferentiated embryonic stem cells. The next step is to use human embryonic stem cells, and the researchers have yet to decide which line of stem cells to use.The mouse embryonic stem cells used in this study were provided by ATCC...

Viral protein influences key cell-signaling pathway

...airmore showed that the p12 protein travels to the network of membranes within the cell known as the rough endoplasmic reticulum (RER). Among other things, the RER helps regulate the amount of calcium in the cell. The investigators found that the p12 protein allows calcium to leak out of the RER, thereby cau...
