Cells use 'noise' to make cell-fate decisions

...noise level within the bacterial cells, they could prevent the cells' transformation between states, essentially "tuning" cellular behavior. "The amplitude of cellular noise correlates with the probability of triggering differentiation," Dr. Süel said. "This is experimental evidence that a genetic circuit...

Leukemic cells find safe haven in bone marrow

...to block ASNS should be tested to see if they also prevent mesenchymal cells from making this amino acid. In addition, the ability of mesenchymal cells to make asparagine might be decreased by cancer drugs that are already known to disrupt the activity of those cells. "Because asparaginase is so widely u...
