Project description:Menin, the product of the MEN1 gene in humans (Men1 in mice), is responsible for the inherited tumor syndrome, multiple endocrine neoplasia type 1 (MEN1). menin interacts with the trithorax group (trxG) proteins (Drosophila) and the mixed-lineage leukemia (MLL) (humans) histone methyltransferase (HMTase) complex, and it alters histone tail modifications and the transcription of target genes. To explore a potential functional implication of menin in HCC, we stably transfected HepG2 or L-02 cells with either vectors or constructs expressing MEN1. A cDNA microarray analysis was performed on HepG2 or L-02 cells with either vectors or constructs expressing MEN1. To obtain a broader understanding of the molecular network of menin in HCC, the whole genome microarray expression profiling was performed on HepG2 or L-02 cells with either vectors or constructs expressing MEN1.

Project description:Polycomb group (PcG) proteins including EZH2, SUZ12 ,BMI1,CBX8 and so on, which specifically catalyze trimethylation of histone 3 lysine 27 (H3K27me3), and methylated H3K27 can be recognized by other specific binding proteins to compress chromatin structure, leading to the transcriptional repression of the target genes. To explore a potential functional implication of PcG components in HCC, we stably transfected HepG2 cells with either vectors or constructs expressing shRNA that specifically targets EZH2, SUZ12, BMI1, or CBX8. A cDNA microarray analysis was performed on shRNA KDs of EZH2, SUZ12, BMI1, or CBX8 HepG2 cells. To obtain a broader understanding of the molecular network of PcG in HCC, the whole genome microarray expression profiling was performed on shRNA KDs of EZH2, SUZ12, BMI1, or CBX8 HepG2 cells.

Project description:Multiple endocrine neoplasia type I (MEN1) is a familial cancer syndrome characterized primarily by tumors of multiple endocrine glands. The gene for MEN1 encodes a ubiquitously expressed tumor suppressor protein called menin. Menin was recently shown to interact with several components of a trithorax family histone methyltransferase complex including ASH2, Rbbp5, WDR5, and the leukemia proto-oncoprotein MLL. To elucidate menin's role as a tumor suppressor and gain insights into the endocrine-specific tumor phenotype in MEN1, we mapped the genomic binding sites of menin, MLL1, and Rbbp5, to approximately 20,000 promoters in HeLa S3, HepG2, and pancreatic islet cells using the strategy of chromatin-immunoprecipitation coupled with microarray analysis. We found that menin, MLL1, and Rbbp5 localize to the promoters of thousands of human genes but do not always bind together. These data suggest that menin functions as a general regulator of transcription. Keywords: ChIP/chip NHGRI Menin ChIP-Chip

Project description:SMARCA2 and SMARCA4 are two mutually exclusive ATPase subunits of SWI/SNF complex. SMARCA4 deficient lung cancer population selectively depend on SMARCA2 for cancer growth phenotype. Rescue experiments with ectopic expression of wild-type, bromodomain mutant and ATPase dead SMARCA2 and SMARCA4 highlight that ATPase domain is the drug target. In this study, we performed genome-wide microarray and differential gene expression profiling on isogenic lung cancer lines expressing cDNA rescue constructs for wild-type, bromodomain mutant and ATPase dead SMARCA2 and SMARCA4
