Transcriptomics analysis of gene expression in human urothelial carcinoma of the bladder (UCB) and adjacent normal tissues.

Project description:36 cases of UCB and 29 adjacent normal bladder tissues (22 pairs) were derived from patients diagnosed with UCB and received radial cystectomy at Sun Yat-sen University Cancer Center (SYSUCC, Guangzhou, China). Total RNA was isolated using TRIzol® Reagent (Ambion). The RNA concentration and quality were determined with NanoDrop, Qubit and agarose gel analysis. The Dynabeads® mRNA Purification Kit (Ambion) was used to enrich the mRNAs, which were used as templates for RNA-Seq library construction. RNA-Seq libraries was directly constructed by using KAPA mRNA Stranded mRNA-Seq Kit (KAPA) according to the manufacturer’s instructions. The libraries were sequenced on the Illumina HiSeq X-Ten platform at Novogene (Tianjin, CA) with paired-end 150 bp read length. The different genes expression between the UCB and adjacent normal tissues were detected. Several genes related to cancer pathways were dysregulated.

RNA m5C analysis in human urothelial carcinoma of the bladder (UCB) and adjacent normal tissues.

Project description:36 cases of UCB and 29 adjacent normal bladder tissues (22 pairs) were derived from patients diagnosed with UCB and received radial cystectomy at Sun Yat-sen University Cancer Center (SYSUCC, Guangzhou, China).Total RNA was isolated using TRIzol® Reagent (Ambion). The RNA concentration and quality were determined with NanoDrop, Qubit and agarose gel analysis. The Dynabeads® mRNA Purification Kit (Ambion) was used to enrich the mRNAs, which were used as templates for RNA-BisSeq library construction. For RNA-BisSeq, bisulfite-treated mRNAs were first subjected to reverse transcription with ACT hexamers and Superscript II Reverse Transcriptase (Invitrogen), and the following processes were carried out with KAPA mRNA Stranded mRNA-Seq Kit (KAPA) according to the manufacturer’s instructions. The libraries were sequenced on the Illumina HiSeq X-Ten platform at Novogene (Tianjin, CA) with paired-end 150 bp read length. The m5C sites were called using meRanCall from meRanTK (FDR < 0.01). The differential m5C sites were detected and the hypermethylated m5C in UCB samples correlates with oncogene mRNA overexpression in UCBs.

Gene expression signatures for bladder cancer tissues and normal adjacent 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.

Single cell transcriptomes of mouse bladder urothelium uncover novel cell type markers and urothelial differentiation characteristics.

Project description:Objectives: Much of the information to date in terms of subtypes and function of bladder urothelial cells were derived from anatomical location or by the expression of a small number of marker genes. To have a comprehensive map of the cellular anatomy of bladder urothelial cells, we performed single-cell RNA-sequencing to thoroughly characterize mouse bladder urothelium. Materials and methods: A total of 18,917 single cells from mouse bladder urothelium was analyzed by unbiased single-cell RNA sequencing. The expression of the novel cell marker was confirmed by immunofluorescence using urinary tract infections models. Results: Unsupervised clustering analysis identified 8 transcriptionally distinct cell subpopulations from mouse bladder urothelial cells. We discovered a novel type of bladder urothelial cells marked by Plxna4 that may be involved with host response and wound healing. We also found a group of basal-like cells labeled by ASPM that could be the progenitor cells of adult bladder urothelium. ASPM+ urothelial cells are significantly increased after injury by UPEC. In addition, specific transcription factors were found to be associated with urothelial cell differentiation. At the last, a number of interstitial cystitis/bladder pain syndrome-regulating genes were found differentially expressed among different urothelial cell subpopulations. Conclusions: Our study provides a comprehensive characterization of bladder urothelial cells, which is fundamental to understanding the biology of bladder urothelium and associated bladder disease.
