Our study demonstrates that PTHrP is a substrate for PSA. The cleavage of the amino-terminal portion of PTHrP completely disrupts its ability to interact with the PTH/PTHrP receptor and thus inhibits its PTH-like activity. | Our data show that PSA proteolytically cleaves PTHrP (1-34) after either residue 22 or 23, generating three peptide fragments. |

Ectopic expression of ebp1, a member of the PA2G4 family, inhibits the proliferation and induces the differentiation of human breast and prostate cancer cell lines. Ebp1 inhibits transcription of E2F1 and androgen receptor regulated genes such as prostate specific antigen (PSA) through its interactions with histone deacetylases (HDACs) |

To define a mechanism for repression of AR function, we demonstrate that AR activity is specifically down-regulated by the histone deacetylase activity of HDAC1. Furthermore, using both mammalian two-hybrid and immunoprecipitation experiments, we show that AR and HDAC1 interact, suggestive of a direct role for down-regulation of AR activity by HDAC1. In chromatin immunoprecipitation assays, we provide evidence that AR, Tip60, and HDAC1 form a trimeric complex upon the endogenous AR-responsive PSA promoter, suggesting that acetylation and deacetylation of the AR is an important mechanism for regulating transcriptional activity. |

Prostate-specific antigen was found to specifically cleave PTHrP 1-141 in a time- and dose-dependent manner.|The preferred PSA cleavage site of PTHrP 1-141 was determined to be at the carboxyl-terminus of phenylalanine 23, consistent with chymotryptic-like enzymatic activity of PSA. Cleavage of PTHrP by PSA completely abolished the ability of PTHrP to stimulate cAMP production. |

The PSA promoter activity was detected by transient expression assay in the PC-J and LNCaP cells but not in androgen insensitive PC-3 cells. When the PC-J cells were cotransfected with androgen receptor, androgen receptor coactivators and PSA reporter vector cells, the reporter assays indicated that nuclear receptor coactivator 4 (NCOA4) but not androgen receptor activator 24 (ARA24) increased the sensitivity and maximum stimulation of dihydrotestosterone (DHT)-inducing PSA promoter activity. |

We characterized four Sp1/Sp3 binding sites in the proximal promoter of the PSA gene. In a luciferase assay, these sites contributed to the basal promoter activity in prostate cancer cells. In an electrophoretic mobility shift assay and chromatin immunoprecipitation assay, we confirmed that Sp1 and Sp3 bind to these sites. Overexpression of wild-type Sp1 and Sp3 further upregulated the promoter activity, whereas overexpression of the Sp1 dominant-negative form or addition of mithramycin A significantly reduced the promoter activity and the endogenous mRNA level of PSA. |
