Project description:The polycomb group (PcG) protein, EZH2, possesses oncogenic properties for which the underlying mechanism is unclear. In this set of experiments, we sought to identify a robust set of Suz12-occupied gene promoters in prostate cancer cell lines. Genome-wide location analysis (ChIP-chip) of SUZ12 was performed in both the PC3 and LNCaP prostate cancer cell lines using an IgG ChIP-chip as a control. Keywords: ChIP-chip

There are total 3 hybridizations, including IgG ChIP-chip of PC3 cells, Suz12 ChIP-chip of PC3 and LNCaP cells.

Project description:Here we report an approach that has permitted us to uncover the sites and mechanisms of action of a drug, referred to as SD70, initially identified by phenotypic screening for inhibitors of ligand and genotoxic stress-induced translocations in prostate cancer cells. Based on synthesis of a derivatized form of SD70 that permits its application for a ChIP-seq-like approach, referred to as Drug-seq, we were next able to efficiently map the genome-wide binding locations of this small molecule, revealing that it largely co-localized with androgen receptor (AR) on regulatory enhancers. Based on these observations, we performed the appropriate global analyses to ascertain that SD70 inhibits the androgen-dependent AR program, and prostate cancer cell growth, acting, at least in part, by functionally inhibiting the jumonji (JMJ) domain-containing demethylase, KDM4C. Drug-seq represents a powerful strategy for new drug development by mapping genome-wide location of small molecules, a powerful adjunct to contemporary drug development strategies. Drug-seq assay followed by high-throughput sequencing (HT-seq).

Project description:Kynureninase is a member of a large family of catalytically diverse but structurally homologous pyridoxal 5'-phosphate (PLP) dependent enzymes known as the aspartate aminotransferase superfamily or alpha-family. The Homo sapiens and other eukaryotic constitutive kynureninases preferentially catalyze the hydrolytic cleavage of 3-hydroxy-l-kynurenine to produce 3-hydroxyanthranilate and l-alanine, while l-kynurenine is the substrate of many prokaryotic inducible kynureninases. The human enzyme was cloned with an N-terminal hexahistidine tag, expressed, and purified from a bacterial expression system using Ni metal ion affinity chromatography. Kinetic characterization of the recombinant enzyme reveals classic Michaelis-Menten behavior, with a Km of 28.3 +/- 1.9 microM and a specific activity of 1.75 micromol min-1 mg-1 for 3-hydroxy-dl-kynurenine. Crystals of recombinant kynureninase that diffracted to 2.0 A were obtained, and the atomic structure of the PLP-bound holoenzyme was determined by molecular replacement using the Pseudomonas fluorescens kynureninase structure (PDB entry 1qz9) as the phasing model. A structural superposition with the P. fluorescens kynureninase revealed that these two structures resemble the "open" and "closed" conformations of aspartate aminotransferase. The comparison illustrates the dynamic nature of these proteins' small domains and reveals a role for Arg-434 similar to its role in other AAT alpha-family members. Docking of 3-hydroxy-l-kynurenine into the human kynureninase active site suggests that Asn-333 and His-102 are involved in substrate binding and molecular discrimination between inducible and constitutive kynureninase substrates.
