Yale Scientists Find MicroRNA Regulates Ras Cancer Gene

...ound that these worms require let-7 RNA for normal development to occur. Without it, cells do not stop dividing and fail to differentiate into the normal structures of the worm ?instead they make an excess of their cells. After identifying let-7 as a cell division regulator, Slack's team used bioinformatics and...

Scientists rid stem cell culture of key animal cells

...and a co-author of the Nature Methods paper. "This development is a good step in that direction. Also, clinically, the feeder cells were one of the main sources of potential contamination with pathogens, so their elimination should improve safety. However, not all the animal components have been removed from the...

Protein Packages Found To Activate Genes; May Be What Regulates Development And Disease

...nown specifics of how genes get switched on during development of the human body and in diseases such as cancer. "Each type of cell in our bodies contains the same genes. What makes them do different things involves which genes are turned on," notes Bradley Bernstein, a pathologist at Harvard Medical School. He...
