A Scheme for binding sequence and sites of PPARG2 binding to the transcription factor-binding site near the AKAP12 gene promoter region. TSS, transcription start site. B ChIP assay revealing the direct binding of PPARG2 to the AKAP12 gene promoter in PC3 cells between the EV and PPARG2 group. The enriched DNA fragments within the AKAP12 gene promoter using IgG and an anti-PPARG2 antibody were amplified by PCR. Total input was used as a positive control. *P < 0.05, **P < 0.01 vs. EV group. C Serially truncated and mutated AKAP12 gene promoter constructs were co-transfected with siPPARG2 or siControl into PC3 cells, and the relative luciferase activities were determined. *P < 0.05 vs. siControl group. D Proposed graphic model for PPARG2-AKAP12 axis-mediated epigenetic regulation mechanism of proliferation, migration, and invasion in PCA cells.
