Transcriptome profiling of human urothelial carcinoma cell lines RT-112, VM-Cub-1, SW1710, UMUC3 and a benign urothelial control HBLAK engineered to stably express HDAC5 against their vector control

ABSTRACT: Aberrant expression of histone deacetylases (HDACs) and their activity are associated with a broad range of tumor development. However, based on cell or tissue types, class IIA HDACs such as HDAC4 and HDAC5 may facilitate or inhibit cancer progression. The goal of this project is to examine the gene expression changes caused by HDAC5 expression. Here, we studied the effects of stable expression of HDAC5 (that is normally downregulated or have a weak basal expression) in four urothelial carcinoma (UC) cell lines (RT112, VM-Cub-1, SW1710, and UM-UC-3) by rRNA-depleted RNA-sequencing in comparison to their vector controls. We observed that HDAC5 expression in VM-Cub-1 triggered a drastic phenotype change from an epitheloid to a mesenchymal (i.e., epithelial-mesenchymal transition, EMT) and altogether diminished cell proliferation of the other three cell lines. Our RNA-seq data are in line with the phenotypic transformation of VM-Cub-1. In addition, we also performed a gene expression profiling of HBLAK, a spontaneously immortalized from primary human bladder epithelial cells that can be directly compared with the four UC vector cells. HBLAK vector cells only were included for RNA-seq as the cells failed to express HDAC5 after lentiviral transduction and selection.

Class I histone deacetylases (HDACs) generally promote cell proliferation and tumorigenesis, whereas class IIA HDACs like HDAC4 and HDAC5 may promote or impede cancer development in a tissue-dependent manner. In urothelial carcinoma (UC), HDAC5 is often downregulated. Accordingly, HDAC5 was weakly expressed in UC cell lines suggesting a possible tumor-suppressive function. We therefore characterized the effects of stable HDAC5 expression in four UC cell lines (RT112, VM-Cub-1, SW1710 and UM-UC-3 ...[more]

Project description:Even though urothelial cancer (UC) is the fourth common tumor type among males, progress in treatment development has been deficient. Pathological assessment provides the urologists with only a broad classification, complicated by frequent disagreement among pathologist and the co-existence of different grading systems. Consequently, there is a great need for an objective, reproducible and biologically relevant classification system to make treatment more efficient. In the present investigation we present a molecular taxonomy for UC stratification based on integrated genomics. We used gene expression profiles from 308 UC to define seven molecular subtypes using step-by-step partitions and a bootstrap approach. Results were validated in three independent and publically available data sets. The subtypes differ significantly with respect to expression of cell cycle genes, of receptor tyrosine kinases particularity FGFR3, ERBB2 (HER2), and EGFR, of an FGFR3 associated gene expression signature, of cytokaratins, and of cell adhesion genes. The subtypes also differ significantly with respect to FGFR3, PIK3CA, and TP53 mutations. The expression of key proteins was validated by IHC on TMA. A further inspection indicated that the subtypes could be reduced to four major types of UC; Urobasal/D-driven, Genomically unstable/E-driven, Evolved urobasal, and Basal/SCC like, with characteristic and highly divergent molecular phenotypes. We show that the molecular subtypes cut across pathological classification and that tumors classified as one subtype maintain their characteristic molecular phenotype irrespective of pathological stage and grade. Available data from the Drugbank database and the Cochrane central registry of controlled trials indicate that susceptibility to specific drugs is more likely to be associated with the molecular stratification than with pathological classification. The presented molecular taxonomy stratifies UC into subtypes with distinct molecular phenotypes and biological properties. We anticipate that the molecular taxonomy will be a useful tool in future clinical investigations. Total RNA from fresh-frozen resection samples of 308 urothelial carcinomas was hybridized to the Illumina HumanHT-12 V3.0 expression beadchip arrays (Illumina Inc) at the SCIBLU Genomics Centre at Lund University Sweden (http://www.lth.se/sciblu). Supplementary files: GSE32894_non-normalized_308UCsamples.txt file = Raw intensity values for 308 UC (urothelial tumor) samples subjected only to background correction.

This dataset partly overlaps with Series GSE32549. Names of the overlapping sample names are the same, but the title of each sample is unique to the hybridization.
