Abstract
Identification and functional characterization of cis-regulatory elements in human PPARD gene. We used various bioinformatic tools on the publicly available human genome and Encyclopedia of DNA Elements databases to explore potential cis-regulatory elements in PPARD gene region. We predicted an insulator and an enhancer element in intron 2 of PPARD gene. Functional characterization using transient transfection, reporter assay and CTCF binding confirmed the insulator status. However, the predicted enhancer element showed repressor/silencer activity. Finally, we observed a potential interaction between these two cis-regulatory elements which is in agreement with 5C-Encyclopedia of DNA Elements data. We report two functionally validated cis-regulatory elements in PPARD gene which will aid in understanding its regulation and role in metabolic functions.
