Comparison of gene expression profiling of human non-muscle invasive bladder cancer and muscle invasive bladder cancer

ABSTRACT: The biological behaviors, clinical treatment, prognosis of nonmuscle-invasive bladder cancers (NMIBCs) and muscle-invasive bladder cancers (MIBCs) are distinct. Therefore, we performed high-through microarray screening of mRNA expression in 30 bladder tumors, to filter out some of the differential expression genes in NMIBCs and MIBCs.A total of 11 Genes in MIBCs versus in NMIBCs were considered differentially transcribed if they were transcribed ≤2.0 fold change and p<0.001 by unpaired T-test, including 9 up-regulated genes and 2 down-regulated genes in MIBCs (NR4A2, PLK3, CYR61, APOLD1, C13ORF33, LIG4, RBMS3, PCK2, AK098422, HSD17B3, RTN4). These candidate genes were validated in further and provide further insight into the discovery of new putative markers to identify MIBCs preoperatively.

Transcriptome analysis reveals anti-cancer effects of Isorhapontigenin (ISO) on human high invasive bladder cancer cells

Project description:Bladder cancer, the most common malignancy of the urinary tract, has a poor overall survival rate if the tumor becomes muscle invasive. The discovery and evaluation of new alternative medications targeting high-grade muscle invasive bladder cancer (MIBC) are of tremendous importance in reducing bladder cancer mortality. Isorhapontigenin (ISO), a stilbene derivative from Chinese herb Gnetum cleistostachyum, exhibits a strong anti-cancer effect on MIBCs. Here, we report the whole transcriptome profiling of ISO-treated human bladder cancer T24 cells. A total of 1047 differentially expressed genes (DEGs) were identified, including 596 downregulated and 451 upregulated genes. Functional annotation and pathway analysis revealed that ISO treatment induced massive changes in gene expression associated with cell movement, migration, invasion, metabolism, proliferation, and angiogenesis. Additionally, ISO treatment activated genes involved in the inflammatory response but repressed genes involved in hypoxia signaling, glycolysis, the actin cytoskeleton, and the tumor microenvironment. In summary, our whole transcriptome analysis demonstrated a shifted metabolism and altered actin cytoskeleton in ISO treated T24 cells, which subsequently contribute to tumor microenvironment remodeling that suppresses tumor growth and progression.

Recurrence in non-muscle invasive bladder cancer

Project description:Although non muscle-invasive bladder cancer can be treated successfully by surgical resection, there is a high rate of recurrence, which frequently develops into an invasive form of cancer. Due to the lack of marker molecules to predict recurrence, it is currently recommended that after resection each patient is screened via cystoscopy at least twice a year. This results in a psychic burden to the patient and substantial economic costs to the health care system. Using antibody microarrays targeting 724 different cancer-related proteins, we studied protein profiles of patients with and without recurrence. The analysis revealed 255 proteins of differential abundance. Most are involved in the regulation and execution of apoptosis and cell proliferation. For prognosis, a signature of 20 proteins was determined that predicts bladder cancer recurrence with 100% sensitivity and 80% specificity. As a measure of overall accuracy, the area under the curve (AUC) value was found to be 90%. This is well within a clinically relevant window of quality and should support decision making about the stringency of surveillance or even different treatment options.

Impact of Immune and Stromal Infiltration on Outcomes Following Bladder-Sparing Trimodality Therapy for Muscle-Invasive Bladder Cancer

Project description:Background: Bladder-sparing trimodality therapy (TMT) is an alternative to radical cystectomy (RC) for muscle-invasive bladder cancer (MIBC), and biomarkers to inform therapy selection are needed. Objective: To evaluate immune and stromal signatures in MIBC treated with TMT.

Transcriptional profiling of tumor-associated blood vessels in invasive bladder cancer

Project description:Tumor-associated blood vessels differ from normal vessels at the morphological and molecular level. Proteins that are only present on tumor vessels may serve as biomarkers and as therapeutic targets for inhibition of angiogenesis in cancer. Comparing the transcriptional profiles of blood vascular endothelium from human invasive bladder cancer and from normal bladder tissue, we found several markers that could serve as novel biomarkers or therapeutic targets. In this dataset, we include the expression data obtained from laser capture microdissected (LCM) vessels isolated from tumor and bladder normal tissue. 10 samples were analyzed. We compared expression of tumor associated blood vessels with expression of vessels in the normal bladder tissue using Genespring GX 12.

Kinome expression profiling of muscle invasive bladder cancer (MIBC) patients

Project description:Muscle invasive bladder cancer (MIBC) is one of the aggressive cancer with limited treatment options. Targeted gene expression profiling in normal and tumor samples from MIBC patients could aid in identification of potential therapeutic targets. Thus we used kinase specific panel to study their expression pattern and to identify targetable genes.

FLI1 and FRA1 transcription factors drive the transcriptional regulatory networks characterizing muscle invasive bladder cancer

Project description:Bladder cancer is mostly present in the form of urothelium carcinoma, causing over 150.000 deaths each year. Its histopathological classification as muscle invasive and non-muscle invasive is the most prominent aspect, affecting the prognosis and progression of this disease. In this study, we defined the active regulatory landscape of MIBC and NMIBC cell lines using H3K27ac-seq and used an integrative data approach to combine our findings with existing data. Our analysis revealed FRA1 and FLI1 as the two critical transcription factors differentially regulating MIBC regulatory landscape. Importantly, we show that FRA1 and FLI1 regulate the genes involved in epithelial cell migration and cell junction organization. Knock-down of FRA1 and FLI1 in MIBC revealed the downregulation of several EMT-related genes such as MAP4K4 and FLOT1. Further, ChIP-SICAP performed for FRA1 and FLI1 enabled us to infer chromatin binding partners of these two transcription factors and link this information with their target genes, providing a comprehensive regulatory circuit for the genes implicated in invasive ability of the bladder cancer cells. Finally, we show that knock-down of FRA1 and FLI1 results in statistically significant less migration of cells using IC-CHIP assays. Our results collectively highlight the role of these two transcription factors in invasive characteristics of bladder cancer in selection and design of targeted options for treatment of MIBC.
