Fig. 3. HOXA5 binds to the p53 promoter and activates p53 signaling in both HSFb and KFb.

Fig. 3

A, B Luciferase assay data showed that HOXA5 activated the expression of p53 promoter reporter gene in KFb and HSFb. C, D ChIP data showed a direct interaction between HOXA5 and p53. 6 kb:the 6 kb upstream of the transcription start site, was used as a negative control for the transcription start site. E, F qPCR and western blot data showed that the overexpression of HOXA5 enhanced the expression of p21 and Mdm2, which are downstream targets of p53. *p < 0.05, **p < 0.01.
