X
Inactivation Seen as Contact Sport
At an early stage in a female embryo’s development, one of the two X chromosomes
in each of its cells becomes inactivated. In two recent papers, the lab of Jeannie
Lee makes important breakthroughs in uncovering how the X chromosomes decide
their fate. One study shows that the chromosomes literally get together before
one of them bows out. The other paper sheds light on the inactivating mechanism,
how an RNA called Xist gets switched on in order to envelop the future inactive
chromosome.
