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: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.
