Genes in Same Organs Seem to Vary by Gender
Thousands of genes behave differently in the same organs of males and females, researchers reported Friday, a finding that may help explain why men and women have different responses to drugs and diseases.
Their study of brain, liver, fat and muscle tissue from mice showed that the level of activity of a gene varied according to sex. The same is almost certainly true of humans, the team at UCLA reported in the August issue of Genome Research. The smallest differences were in brain tissue, they found.
