LINE-1 family member GCRG123 gene is up-regulated in human gastric signet-ring cell carcinoma

World Journal of Gastroenterology 2008年第5期14卷 758-763页

作者： gang-shi wang meng-wei wang ben-yan wu xin-yan yang wei-hua wang wei-di you Department of Gerontal Gastroenterology General Hospital of Chinese PLA Beijing 100853 China

AIM： To analyze the expression profiles of a human gastriccancer-related gene, GCRG123, in human gastric signetring cell carcinoma tissues, and to perform bioinformatics analysis on GCRG123.METHODS： In situ hybridization was used to explore the GCRG123 expression pattern in paraffin-embedded gastric tissues, including 15 cases of signet-ring cell carcinoma, 15 of intestinal-type adenocarcinoma, and 15 of normal gastric mucosa. Northern blotting was used to analyze the differences in GCRG123 expression between stomach signet-ring cell carcinoma and intestinal-type adenocarcinoma tissues. Online software, including BLAST, Multalin and BLAT, were applied for bioinformatics analysis. National Center for Biotechnology Information （NCBI） and the University of California Santa Cruz （UCSC） databases were used for the analyses.RESULTS： The in situ hybridization signal appeared as blue precipitates restricted to the cytoplasm. Ten out of 15 cases of gastric signet ring cell carcinoma, normal gastric mucosal epithelium and pyloric glands showed high GCRG123 expression. Low GCRG123 expression was observed in gastric intestinal-type adenocarcinoma and normal gastric glands. Northern blotting revealed that GCRG123 was up-regulated in signet-ring cell carcinoma tissue but down-regulated in intestinal-type adenocarcinoma tissue. BLAST and Multalin analyses revealed that the GCRG123 sequence had 92% similarity with the ORF2 sequence of human long interspersed nuclear element retrotransposons （LINE-1, L1）. BLAT analysis indicated that GCRG123 mapped to all chromosomes. GCRG123 was found to integrate in the intron-17 and -23 of Rb, 5＇ flanking region of IL-2 and clotting factor Ⅸ genes.CONCLUSION： GCRG123, an active member of the Lt family, was up-regulated in human gastric signet-ring cell carcinoma.

AIM: To clone genes that may predispose us to humangastric cancer and to analyze it's expression in gastric ***: Specimens of paired tumor, paratumor andnormal gastric mucosa tissues collected from fifteen patientswho suffered from stomach antrum adenocarcinoma wereused for analysis. Seven out of the fifteen cases were firststudied by fluorescent differential display reversetranscription polymerase chain reaction (DDTR-PCR) *** differentially expressed bands of interest were cloned,analyzed by Northern blot, sequencing and RT-PCR. ThroughBLAST, the sequencing results were compared with GenBankdatabase for homology analysis. In situ hybridization withdiG-labeled cRNA probes was used to analyze the expressionof interesting cDNA bands in paraffin embedded pairednormal gastric mucosa and cancer tissues isolated from 30gastric adenocarcinoma ***: DDRT-PCR showed that one of the interestingcDNA bands, which was named W2, expressed much higherin all seven tested tumor and paratumor samples than intheir normal counterparts, it was sub-cloned into a pGEM-TEasy vector. Two subclones were subsequently *** of the subclone, GCRG224, was studied further. Thesequencing result showed that GCRG224 consisted of 1 159base pairs and had one open reading frame (ORF). It locatedat human chromosome 11q14. No homologue was found inGenBank database with GCRG224-ORF. This nucleotidesequence data were submitted to GenBank with accessionNo. AF438406. RT-PCR showed that GCRG224 expressedhigher in 11/15 gastric cancer tissues than in non-tumortissues. However, the result of Northern blot analysis showeda higher GCRG224 expression in the non-tumor tissue thanin the tumor one. Human multiple tissue Northern blot analysisrevealed that GCRG224 also expressed in human normal colontissue, and peripheral blood leukocyte. In situ hybridizationanalysis showed that only 5/30 adenocarcinoma, 3/18dysplasia and 6/18 intestinal metaplasia showed higherGCRG224 express

Improved Pattern Clustering Algorithm for Recognizing Transversal distribution of Steel Strip Thickness

引用

Journal of Iron and Steel Research International 2009年第5期16卷 50-55页

作者： TANG Cheng-long wang shi-gang LIANG Qin-hua XU wei School of Mechanical and Dynamical Engineering Shanghai Jiao Tong University Shanghai 200240 China

Transversal distribution of the steel strip thickness in the entry section of the cold rolling mill seriously affects to the flatness and transversal thickness precision of the final products. Pattern clustering method is introduced into the steel rolling field and used in the patterns recognition of transversal distribution of the steel strip thickness. The well-known k-means clustering algorithm has the advantage of being easily completed, but still has some drawbacks. An improved k-means clustering algorithm is presented, and the main improvements include：（1） the initial clustering points are preselected according to the density queue of data objects; and （2） Mahalanobis distance is applied instead of Euclidean distance in the actual application. Compared to the patterns obtained from the common kmeans algorithm, the patterns identified by the improved algorithm show that the improved clustering algorithm is well suitable for the patterns＇ recognition of transversal distribution of steel strip thickness and it will be useful in online quality control system.
