Differential Gene Expression Following Irradiation

Here's a neat study from last year that examines which gene networks are expressed in human skin material in response to low (10 cGy) and high dose (100 cGy) x-ray irradiation.

There is some overlap and some differences between the differential gene expressions at the two doses.

As the authors point out, other studies (using other tissues, doses, radiation type, etc.) have shown similar results.
