(Submitter supplied) Kruppel-like transcription factor 5 (Klf5) is expressed during late embryogenesis in the forming murine bladder urothelium. Targeted disruption of the Klf5flox alleles by the ShhGfpCre transgene resulted in failure of the bladder urothelium to mature accompanied by hydronephrosis, hydroureter, and vesicoureteric reflux in all E18.5 fetuses. The bladder urothelium did not stratify nor did it express terminal differentiation markers characteristic of basal, intermediate, and umbrella cells including keratins 20, 14, and 5, and uroplakins. more...

(Submitter supplied) To identify putative KLF5 target genes that may mediate villus morphogenesis and epithelial maturation, we performed microarray analysis on intestinal samples isolated on E14.5, prior to the initiation of villus formation. Total RNA was isolated from dissected intestine segments located ~1.5 cm anterior to the cecum from E14.5 Klf5D/D and Klf5wt/wtShhEGFP/Cre+ embryos (n=3 samples/genotype, each sample a pool of two intestines). more...

(Submitter supplied) Skin and bladder epithelia form effective permeability barriers through the activation of distinct differentiation gene programs. Employing a genome-wide gene expression study, we identified transcription regulators whose expression correlates highly with that of differentiation markers both in bladder and skin, including the Grainyhead factor Get1/Grhl3, already known to be important for epidermal barrier formation. more...

(Submitter supplied) Activation of the Ras/Erk pathway upregulates expression of the Kruppel-like Factor 5 (KLF5) transcription factor, and KLF5 is a downstream mediator of Ras oncogenic signaling. Specifically, in bladder and colon cancer cell lines KLF5 upregulates the Ras-pathway target gene cyclin D1, and facilitates entry into the S phase of the cell cycle. Ras mutations are common in lung cancer, but a role for KLF5 in lung tumorigenesis has not been defined. more...

(Submitter supplied) Deletion of Klf5 in satellite cells impaired muscle regeneration due to a failure of differentiation. Mechanistically, Klf5 controls transcription of muscle genes by interacting with MyoD and Mef2. These findings provide a potential intervention into the process of muscle regeneration through modulation of Klf5.

(Submitter supplied) The essential functions of intestinal stem cells (ISCs) are to self-renew and give rise to progenitors that subsequently differentiate to absorptive or secretory cells, thus maintaining homeostasis in the intestinal epithelium. In this study, we analyzed the transcriptomic and epigenetic changes of ISCs with Klf5 deletion to understand the role of KLF5 in ISC identity and functions.

(Submitter supplied) 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. more...

(Submitter supplied) KLF5 is a basic transcription factor that regulates multiple biological processes, but its function in tumorigenesis appears contradictory in the current literature, with some studies showing tumor suppressor activity and others showing tumor promoting activity. In this study, we examined the function of Klf5 in prostatic tumorigenesis using mice with prostate specific deletion of Klf5 and Pten, both of which are frequently deleted in human prostate cancer. more...

(Submitter supplied) Peroxisome Proliferator-Activated Receptor-gamma (PPARG) is a nuclear hormone receptor that was originally described as a master regulator of adipogenesis but could also promote cellular differentiation in a number of epithelium. PPARG also serves as an important regulator in anti-inflammatory activity after a variety of injuries, acting in part by antagonizing the NF-kB pathway. Moreover, the expression of PPARG is strongly down regulated in the basal subtype of bladder cancer, suggesting that its removal might be essential in tumorigenesis. more...

(Submitter supplied) Alveolar epithelial cell fate decisions drive lung development and regeneration. Using transcriptomic and epigenetic profiling coupled with genetic mouse and organoid models, we identified Klf5 as a critical regulator of alveolar epithelial cell fate across the lifespan. During prenatal lung development and alveologenesis, Klf5 enforces alveolar epithelial type 1 (AT1) cell lineage fidelity. While it is dispensable for both adult AT1 and alveolar epithelial type 2 (AT2) cell homeostasis, Klf5 regulates AT2 cell plasticity after injury. more...
