Research Interest:

Ionizing radiation (IR) is a commonly used anti-cancer therapy that targets actively proliferating cells. LGR5+ intestinal stem cells are sensitive to IR damagealthough they are indispensable for regeneration following IR damage. Krüppel-like factor 5 (KLF5) is a zinc-finger transcription factor expressed in proliferating cells, including LGR5+ ISCs, of the intestinal epithelium and is involved in regulation of cell proliferation and differentiation. We observed that KLF5 is expressed in the majority of the MKI67+ proliferating cells in mice undergoing intestinal epithelial regeneration following total-body gamma-irradiation (TBI) injury. I am interested in investigating the role of KLF5 in the regenerative response after radiation injury in the intestinal epithelium.
