Consistently, only 1 of 3 FRTL5-Ras-PATZ1 tumors analyzed, excised at the end of their growth observation, showed Ki67 positivity against 3 out of 3 from control group, even though no significant differences in Ki67 tumor expression—likely due to the low number of specimens analyzed—was detected in the two cohorts of mice (Figure 1c). Here, PATZ1 is linked to neoplasm.
