Project description:Genome-wide DNA methylation profiles were determined on a set of fresh 44 bladder cancer tissues using normal blood as control. DNA amplicons were prepared using Differential Methylation Hybridization (DMH) method, subsequently hybridized on to the Agilent Human CpG island Microarray. The goal was to unravel the DNA methylation patterns in different subgropus of bladder cancer along with finding markers for progresssion and early diagnosis.

Project description:The DNA methylation patterns associated with the development and progression of cancer. The aim of the present study was to identify novel methylation markers that can discriminate between normal and Non-muscle-invasive bladder cancer (NMIBC), and between good and poor prognosis using microarray analysis of DNA methylation and RNA expression patterns in NMIBC patients. From the 24 matched microarray-based DNA methylation and gene expression profiling data set, tumor specific hypermethylated genes were selected and clinical relevance of these genes were verified by quantitative PQS analyses. Methylation statues of several genes were significantly associated with decreased gene expression levels and aggressive clinicopathological characteristics. In multivariate regression analyses, hypermethylation of these genes were the independent predictors of recurrence and progression.

Project description:Using the highly sensitive lncRNA array, we screened the lncRNAs abundant in the human bladder cancer and Adjacent normal bladder tissues, and the function of differentially expressed lncRNAs were analyzed by bioinformatics. The Arraystar Human lncRNA Array (8x15K, Arraystar) and whole human mRNA Array (4x44K, Arraystar) and was used to profile differentially expressed lncRNAs and genes in bladder cancer vs. normal tissues following the manufacturerâs instructions. Briefly, extracted RNA template (1mg) was reversely transcribed into cDNA and digested into fragments with endonucleases. These fragments were labeled with DNA labeling reagent and labeled cDNAs were hybridized to the microarray via incubation at 45°C and rotated at 60 rpm for 17 h. Following washing and staining, the arrays were scanned using a GeneChip Scanner3000 with GeneChip Operating Software.

Project description:In the development and progression of bladder cancer, there are many genetic changes. We established a SD rat orthotopic bladder cancer model through intravesical instillation of N-methyl-nitrosourea and pathologic diagnosis is bladder transtional cell carcinomal (BTCC). We used microarrays to analysis the gene expression changes among these rat bladder carcinoma, adjacent normal tissues and bladder tissues of normal rats. Three paired tumor tissues (Group A) and adjacent normal tissues (Group B) were obtained from 3 SD rats with BTCC, and 3 normal tissues (Group C) obtained from 3 normal SD rats. Affymetrix microarrays analyzed the gene expression changes among above 3 groups of tissues.

Project description:It is well established that low-dose Decitabine treatment can sustain long-term antitumor effects by targeting DNA methylation and altering gene expression32. We performed methylated DNA immunoprecipitation (MEDIP) followed by next-generation sequencing in 5637 cells. Daily Decitabine treatment with 100 nM for 72 hr (with or without 100ng/ml cisplatin treatment) reduced the methylation level at CpG-islands in the genome of 5637 cells . However, this low-dose DEC treatment did not cause a significant reduction of DNA methylation in non-CpG islands regions.Our study represents the first detailed analysis of DNA methylome generated by RNA-seq technology in bladder cancer cells treated with low-dose decitabine. This study help to reveal the direct target genes of decitabine in bladder cancer treatement.

Project description:To identify aberrantly expressed long intergenic noncoding RNAs (lincRNAs) in bladder cancer tissues compared with normal adjacent tissues, we have employed microarray expression profiling as a discovery platform to identify lincRNAs that may play important roles in bladder cancer origin and progression. Samples of fresh frozen cancer tissues, together with normal adjacent tissues (3 cm away from the tumor), were obtained during surgical resection, and total RNA was extracted for microarray analysis. Two pairs of fresh frozen bladder cancer tissues and corresponding normal adjacent tissues were used in the microarray analysis.
