Abstract

We show that 4-amino-5-(4-chlorophenyl)-7-(t-butyl)pyrazolo[3,4-d]pyrimidine (PP2) induces apoptosis and down-regulates the expression of enoyl-CoA hydratase short chain 1 (ECHS1) and peroxiredoxin 3 (PRDX3) in human breast cancer MCF-7 cells. The decrease of ECHS1 and PRDX3 was validated by Western blot and quantitative real-time reverse transcription-PCR in MCF-7 and other carcinoma cells. Knockdown and over-expression of ECHS1 and/or PRDX3 further supported the key role of ECHS1 and PRDX3 in regulation of PP2-induced apoptosis. These results suggest a possible apoptotic pathway whereby down-regulation of ECHS1 and PRDX3 potentiates PP2-induced apoptosis in MCF-7 cells.
