(Submitter supplied) We isolated and selected intestinal adenoma organoids from villin-CreER; Apcflox/flox and villin-CreER; Apcflox/flox; Prox1flox/flox mice and added tamoxifen to induce the deletion of the Apc and Prox1 genes in the intestinal epitheliul ex vivo. Microarray experiments were carried out 7 days after the addition of tamoxifen.

(Submitter supplied) We made intestinal organoid cultures from Villin-CreERT2;Apcflox/flox mice. Organoids were subjected to 4-OH-Tam treatment, whereafter Apc mutant organoids were selected in R-Spondin free medium. DBZ or DMSO treatment was started on day 3. On day 8, organoids were dissociated to obtain single cells and analyzed using the Chromium Single-cell 3'RNA-sequencing system

(Submitter supplied) We isolated and selected intestinal adenoma organoids from Apcmin/+; Rosa26LSL-TdTomato; Prox1-CreERT2 mice. After the selection procedure without growth factors, we induced CreERT2 activity and the transcription of tdTomato to label Prox1+ cells by 300 nM 4-hydroxytamoxifen for 16h. tdTomato+ (Prox1+) and tdTomato- cells (enriched for Prox1- cells) were FACS sorted and total RNA was isolated.

(Submitter supplied) Cancer stem cells (CSCs) are profoundly associated with refractory nature of cancer. A quiescent population of CSCs is responsible for tumorigenesis and chemoresistance in leukemia, whereas neither the presence nor clinical importance of the quiescent CSCs is clearly established in solid tumors. In colon cancer, LGR5 is regarded as a functional marker of CSCs, but heterogeneity among LGR5+ cells was not clearly defined. more...

(Submitter supplied) Here we identify HOXA5 as an important repressor of intestinal stem cell fate in vivo and identify a reciprocal feedback between HOXA5 and Wnt signaling. HOXA5 is suppressed by the Wnt pathway to maintain stemness and becomes active only outside the intestinal crypt where it inhibits Wnt signaling to enforce differentiation. In colon cancer, HOXA5 is down-regulated and its re-expression induces loss of the cancer stem cell phenotype preventing tumor progression and metastasis. more...

(Submitter supplied) Overview: We report here that gene expression in E13.5 wild type (WT) mouse lenses differs from the lenses of mice that conditionally lack the Prox1 transcription factor in the lens of their eyes (Prox1 cKO) as assayed by high throughput RNA sequencing (RNAseq). The methodology outlined herein is similar to a previous RNAseq experiment from our lab (Manthey et al., 2014a)(Geo ascension: GSE 49949), and the filtering and processing criteria for this experiment was published as well.(Manthey et al., 2014b). more...

(Submitter supplied) The homeobox transcription factor Prox1 is expressed in embryonic hepatoblasts and remains expressed in adult hepatocytes. Prox1-null mice show severe deficiencies of liver development, but the underlying mechanisms are unknown. We studied the effects of Prox1 on the transcriptional profile of embryonic day-14 (ED14) met-murine-hepatocytes (ED14-MMH). These immortalized murine hepatoblasts express numerous hepatoblast markers, but not Prox1. more...

(Submitter supplied) Alterations in the expression of key transcription factors can be harmful for pancreatic beta cell homeostasis and could lead to diabetes. This study uncovered that Prox1 overexpression obstructs beta cell maturation and results in severe hyperglycemia. The function of β-cells is key for glucose homeostasis because they supply insulin to the entire body. Genetic or metabolic conditions that disrupt the complex physiology of β-cells can lead to diabetes mellitus, a prevalent life-threatening disease. more...

(Submitter supplied) In our study, we investigated the effect of muscarinic receptor blockade on murine intestinal stem cell activity and differentiation. Following pharmacologic (scopolamine) and genetic muscarinic receptor interruption (M3R-KO, M1R-KO; Vil-Cre x M3R fl/fl, Vil-Cre x M1R fl/fl mice, respectively), we observe a selective, significant expansion of DCLK1-positive tuft cells. This is primarily sensed by endocrine Prox1-positive cells (Prox1-CreERT2 x M3R fl/fl mice), while Lgr5-positive ISCs respond with a reduction of their cellular activity (Lgr5-EGFP-IRES-CreERT2 x M3R fl/fl mice). more...
