Figure 1

The Kelleher lab is interested in the defense of the genome to sources of mutation including transposable elements, UV and ionizing radiation. We the molecular mechanisms that underlie genome defense, natural variation and evolution of these mechanisms.

UV and Ionizing Radiation

Figure 2

UV and ionizing radiation pose a major threat to genome integrity by producing mutations. Organisms defend their genomes against the harmful effects of radiation through physical barriers (UV only) and DNA repair. We are interested in how these defense mechanisms vary between individuals, and how this relates to geographic and seasonal variation in UV and ionizing radiation. This work is also relevant to radiation therapy, which relies on differential radiotolerance between healthy and tumor cells.

Transposable elements

Transposable elements (TEs) are mobile genetic sequences that populate and parasitize genomes. TEs impose a multifaceted mutational burden on their host through insertional inactivation of host genes, participation in ectopic recombination, and the induction of DNA damage. Our research focuses on how the host genome fights back against TEs through small RNA silencing pathways, and how host facilitate the movement of transposable elements through transpositional cofactors.
