Abstract

NKX3.1 is a prostate-specific homeobox gene related strongly to prostate development and prostate cancer. However, little is known about the mechanism for regulation of NKX3.1 in prostate cancer. With RT-PCR and western blot, we found that NKX3.1 expression was enhanced by over-expression of Sp1 at both the mRNA and protein levels in prostate cancer LNCaP cells. To identify the Sp1-elements in the promoter region of NKX3.1, a 521 bp-promoter of human NKX3.1 gene containing three possible Sp1-elements was cloned into the upstream of the luciferase reporter gene in pGL(3)-basic plasmid. With deletion mutation analysis, plasmid construction, EMSA and oligonucleotide decoy technique, two Sp1-elements which located between ?29 to ?43 and -60 to -46 of NKX3.1 gene were identified and proven to be functional elements. It will be important to further study on the functions and the regulatory mechanisms of Sp1 element in NKX3.1 gene expression.
