原始语种摘要: Abstract(#br)The serine–threonine protein phosphatase 2A (PP2A) is a heterotrimeric enzyme family that plays an essential regulatory role in cell growth, differentiation, and apoptosis. Mutations in the genes encoding PP2A-Aα/β subunits are associated with tumorigenesis and other human diseases. To explore whether genetic variations in the promoter region of the PP2A-Aα gene ( PPP2R1A ) and their frequent haplotypes in the Han Chinese population have an impact on transcriptional activity, we collected DNA samples from 63 healthy Chinese donors and searched for genetic variations in the 5′-flanking promoter region of PPP2R1A ( PPP2R1Ap ). Haplotypes were characterized by Haploview analysis and individual subcloning. A set of molecular and functional experiments was performed using reporter...
