Comparable results were obtained for VERL-Fb (another fragment of VERL that shares 40% sequence identity with VERL-Fa) and ENG-C (Fig. 1A), as well as by fusing intracellular proteins (such as cancer-associated human transcription factor GLI (Kinzler et al., 1988)) to a non-secreted version of mMBP (Fig. 1B). This evidence concerns the gene GLI1 and cancer.
