Environmental stressors, as ionizing radiation (terrestrial, space, and UV-radiation), air pollution (including particulate matter [PM]-derived and gaseous), persistent organic pollutants, and metals" activate mobile DNA elements. (uchicago.edu)

Despite the initial enthusiasm and multiple clinical trials, there is still no FDA-approved gene therapy for CF. This review details the history of CF gene therapy and outlines the progress toward the development of a genetic treatment for all people with CF. The cover image is a 3D rendering of a newborn pig lung CT image (image reconstructed by Carley Stewart). (mdpi.com)
