PPARGC1A and acute myeloid leukemia: In our present study, we demonstrated the increased expression of PPAR-α and PGC-1α in the absence of Hif-2α in EtOH-treated AML-12 cells, suggesting that there is a negative correlation between Hif-2α and the PPAR-α/PGC-1α signaling pathway in response to EtOH-induced hepatic lipid metabolism dysfunction.
