Study zeroes in on genes 'at work'

Los Angeles -- U.S. researchers say they're using human gene maps not just to show their location but also which ones interact with each other to help cells thrive.

Scientists at UCLA say their findings will help researchers understand which genes work together as cells grow, function and then die, a university release said Monday.

Humans have about 20,000 different genes that initiate and control all bodily processes, from moving blood through the veins to stimulating the immune system to attack a cold virus.

Not all genes in a cell are active during the processes, but some are almost always engaged in either one-on-one reactions or creating networks involving dozens of genes.
