They are involved in diverse processes, including cellular differentiation, proliferation and apoptosis. Recent evidence also suggests their importance for cancerogenesis. By far the most important model systems in cancer research are mammalian anisms. Thus, we decided to pile prehensive information on mammalian miRNAs, their origin and regulated target genes in an exhaustive,curated database called Argonaute ( Argonaute collects latest information from both literature and other databases. In contrast to current databases on miRNAs like miRBase::Sequences, NONCODE or RNAdb, Argonaute hosts additional information on the origin of an miRNA, . in which host gene it is encoded, its expression in different tissues and its known or proposed function, its potential target genes including Gene Ontology annotation, as well as miRNA families and proteins known to be involved in miRNA processing. Additionally, target genes are linked to an information retrieval system that provides prehensive information from sequence databases and a simultaneous search of MEDLINE with all synonyms of a given gene. The web interface allows the user to 39 get information for a single or multiple miRNAs, either selected or uploaded through a text file. Argonaute currently has information on 839 miRNAs from human, mouse and rat. INTRODUCTION MicroRNAs (miRNAs) are small (21–23 nt) noncoding RNAs that are important regulators of gene expression. They act by base pairing with partially plementary sites in the mRNA of their targets, and either inhibit translation into protein or decrease the stability of the transcript . The number of currently known miRNAs in mammalian systems has risen dramatically in the last year, and predictions about their total number in humans amount up to 1000. miRNAs are transcribed as long primary transcripts (primiRNAs), some of them being polycistronic, which are processed in the cell nucleus by an enzyme called Drosha, yielding precursor miRNAs (premiRNAs) that exhibit a characteristic stem–loop sequence. These are exported into the cytosol where mature miRNAs are generated by the RNase IIItype enzyme Dicer, producing a small doublestranded RNA from which one strand (called miRNA*) is quickly degraded, releasing the small singlestranded miRNA. Translational inhibition, which seems to be the major mode of action in animals, is performed by a riboprotein plex called RNAinduced silencing plex (RISC) consisting of the miRNA and proteins of the argonaute family miRNAs are involved in several cellular processes, including cellular differentiation, anism development and apo。 35 致 謝 光陰似箭,美好的時(shí)光總是過的飛快,轉(zhuǎn) 眼間最美好的大學(xué)生活即將結(jié)束。 此次畢業(yè)設(shè)計(jì) 以 MySQL 作為后臺(tái)數(shù)據(jù)庫(kù),以 Apache 為服務(wù)器,用 PHP 語(yǔ)言構(gòu)建的基因信息的數(shù)據(jù)庫(kù)系統(tǒng)。 圖 DNA 信息成功錄入數(shù)據(jù)庫(kù) 化 功能測(cè)試 基因數(shù)據(jù)庫(kù)管理 系統(tǒng)提供 序列轉(zhuǎn)化為 FASTA 格式,根據(jù)要求可以將輸入的序列 按如下格式輸出:序列 的第一行是由大于號(hào) 打頭 ,然后顯示該序列的長(zhǎng)度, 用于序列標(biāo)記。 } mysql_free_result($result)。 $result=mysql_db_query($mysql_database
