59 練習 試問 FGF2, FGF3, FGF4, FGF8, and FGF9 是否可被 CREB 調控?

60 Whole Genome Search of Candidate Genes by Profile Hidden Markove Model

61 The Binding Element Searching Tool (THE BEST)  Users could build up a customized hidden markov model (HMM) via HMMER program by upload or paste a set of element sequences containing specific transcription factor binding site (in FASTA format) and use this model to search the multi-species promoter region (human, mouse and rat) retrieved from the EnsMart system annotated by ensembl project

62 Motivation  Search for novel regulated target genes by known transcription factor binding sites (ex. ERE) based on multiple alignments Literature search ( promoter activity 、 gel shift assay 、 ChIP )

63 Searching Platform  Hidden Markov Model based search tools Promoter EnsMart Promoter sequence HMMER2.2g Pattern ClustalW Calibrate Build Search Know EREs HMMER2.2g ERE_DB
