TGIF1 immunoreactivity is increased in human rectum after radiotherapy. Pictures are representative of TGIF1 immunostaining of specimens of normal rectal tissue from patients treated with preoperative radiotherapy (n = 12). Tissues were taken distant from the tumor (Normal) and in the irradiation field adjacent to the tumor (Pathological). All images were recorded in normal and pathological areas from the same patient.
