Gene expression of unperturbed young and aged mouse bladders

ABSTRACT: Aging has multifaceted effects on the immune system, but how aging affects tissue-specific immunity is not well-defined. Bladder diseases characterized by chronic inflammation are highly prevalent in older women, but mechanisms by which aging promotes these pathologies remain unknown. Tissue transcriptomics of unperturbed, young, and aged bladders identified a highly altered immune landscape as a fundamental feature of the aging female bladder. Detailed mapping of immune cells using single cell RNA- sequencing revealed novel subsets of macrophages and dendritic cells and unique changes to the immune repertoire in the aged bladder. B and T cells are highly enriched in aged bladders and spontaneously form organized bladder tertiary lymphoid tissues (bTLTs).

Expression data from the bladders of carcinogen-treated mice with genetic Hh pathway manipulation

Project description:Attenuation of Hedgehog (Hh) pathway activity leads to accelerated tumor progression in a mouse model of N-butyl-N-4-hydroxybutyl nitrosamine (BBN) – induced bladder carcinoma. In order to identify genes regulated by the Hh pathway that might be involved in bladder cancer progression, we performed transcriptional profiling of bladders harvested from mice after BBN-exposure, comparing Gli1CreER/WT; Smoflox/WT mice to Gli1CreER/WT; Smoflox/flox mice, which express CreER under control of the Gli1 promoter and carry one or two floxed alleles of the essential Hh pathway transductory component Smoothened (Smo) respectively. Administration of Tamoxifen to these mice results in attenuation of Hh pathway activty to a greater extent in the Gli1CreER/WT;Smoflox/flox mice as compared to Gli1CreER/WT;Smoflox/WT mice, allowing identification of Hh-pathway regulated genes. 6 total samples were analyzed. 3 bladders from Gli1CreER/WT; Smoflox/WT mice and 3 bladders from Gli1CreER/WT; Smoflox/flox mice were analyzed.

The influence of age and sex on the pre-treatment immune microenvironment of a carcinogen induced murine model of bladder cancer

Project description:The incidence of urothelial carcinoma of the bladder is four times higher in males than females; however, females tend to present with a more aggressive disease, a poorer response to immunotherapy and suffer worse clinical outcomes. Recent findings have demonstrated sexual dimorphism in the tumor immune microenvironment of non-muscle invasive bladder cancer and associated clinical outcomes. However, a significant gap in knowledge remains with respect to the current pre-clinical modeling approaches and more precisely recapitulating these differences towards improved therapeutic design. Based on the similarities in mucosal immune physiology between humans and mice, we evaluated the sex and age-related immune alterations in healthy murine bladders. Bulk-RNA sequencing and multiplex immunofluorescence based spatial immune profiling of healthy murine bladders from male and female mice of age groups spanning young to old showed a highly altered immune landscape that exhibited sex and age associated differences, particularly in the context of B cell associated responses. Spatial profiling using markers specific to macrophages, T lymphocytes, B lymphocytes, activated dendritic cells, high endothelial venules, myeloid cells and the PD-L1 immune checkpoint showed sex and age associated differences. Bladders from healthy older female mice showed a higher number of tertiary lymphoid structures (TLSs) compared to both young female and male equivalents. Spatial immune profiling of N-butyl-N-(4-hydroxybutyl) nitrosamine (BBN) carcinogen exposed male and female bladders from young and old mice revealed a similar frequency of TLS formation, sex differences in the bladder immune microenvironment and, age differences in latency of tumor induction. These findings support the incorporation of sex and age as factors in pre-clinical modeling of NMIBC and will potentially advance the field of immunotherapeutic drug development to improve clinical outcomes in NMIBC.

Single-cell transcriptomic map of the human and mouse bladders

Project description:A comprehensive cellular anatomy of normal human bladder is vital to address the cellular origins of benign bladder disease and bladder cancer. The physiological function and pathological changes of bladder are associated with its cell type. To investigate the classification and underlying function of bladder cells, we conducted single-cell RNA sequencing (scRNA seq) of 12,423 cells from human bladder and 12,884 cells from mouse bladder. Here, we show a single-cell transcriptomic map of the human and mouse bladders, including 16 clusters of human bladder cells and 15 clusters of mouse bladder cells. Homology and heterogeneity of human and mouse were compared and analyzed by our study, and indicated that there were both conservative and heterogeneous aspects of human and mouse evolution. We also discovered two novel types of human bladder cells; one type is ADRA2A+ and HRH2+ interstitial cells which may be associated with nerve conduction and allergic reactions; the other type is TNNT1+ epithelial cells that may be different from other epithelial cells in biological function. Collectively, this analysis provides a resource for the discovery of novel cell type, specific transcription factors, signaling receptors, and genes dataset that will help us to study the relationship between cell types and diseases.

Transcription profiling of mouse postnatal day 1 and adult bladders

Project description:The long term objective is to create an encyclopedia of the expression levels of all genes in multiple components of the developing bladder. The central thesis is straightforward. The combination of microdissected and laser capture microdissection (LCM) plus microarray analysis offers a powerful, efficient and effective method for the creation of a global gene expression atlas of the developing urogenital system. Microarrays with essentially complete genome coverage can be used to quantitate expression levels of every gene. The ensuing rapid read-out provides an expression atlas that is more sensitive, more economical and more complete than would be possible by in situ hybridizations alone. The data submitted here represents the gene expression profiles of the embryonic day 14 bladder, urogenital sinus, and urethra. Experiment Overall Design: Bladders, from postnatal day 1 and adult SMGA/EGFP animals were isolated by dissection and total RNA extracted for gene expression analysis using the Affymetrix MOE430 microarray chip.

Expression data from mouse whole bladders of cyclophosphamide-induced cystitis

Project description:To analyze the gene expression of non-bacterial bladdder inflammation, mouse cyclophosphamide(CYP)-induced model of cystitis was adapted. Forty-eight hour after CYP or vehicle treatment, total RNA was extracted from CYP-treated group (CYP150) and control group (CYP0). We used microarrays to detail the gene expression underlying bladder inflammation. Five-week-old female Balbc/A mice were injected intraperitoneally with 150mg/kg body weight of CYP diluted in 15ml/kg body weight of saline. Mice injected with saline alone served as controls. Treated mice were killed 48 hours after administaration and the whole bladders harvested. Total RNA was extracted and microarray analysis was performed.
