Description
Insulin degrading enzyme (IDE) is a major enzyme responsible for insulin degradation in the liver. The modulation of insulin degrading enzyme activity is hypothesized to be a link between T2DM and liver cancer. Results provide insight into role of IDE in proliferation and other cell functions.

Description
We analyzed chromatin dynamics and transcriptional activity of human embryonic stem cell (hESC)-derived cardiac progenitor cells (CPCs) and KDR+/CD34+ endothelial cells generated from cardiogenic or hemogenic mesoderm. Using an unbiased algorithm to hierarchically rank genes modulated at the level of chromatin and transcription, we identified novel candidate regulators of mesodermal lineage determination. HOPX, a non-DNA binding homeodomain protein, was identified as a candidate regulator of blood-forming endothelial cells. We used HOPX reporter and knockout hESCs, as well as hopx loss of function studies in zebrafish, to show the requirement of HOPX in vivo and in vitro in hemato-endothelial lineage specification. Loss of HOPX does not impact endothelial fate specification but markedly reduces primitive hematopoiesis acting at least in part through suppression of Wnt/ß-catenin signaling. Single cell RNA-seq data during mouse hematopoietic development in vivo confirm a role for HOPX in hematopoietic fate. Taken together, we show that HOPX is a novel regulator of hemato-endothelial fate specification in vitro and in vivo that functionally regulates Wnt signaling to modulate primitive hematopoiesis. Overall design: 2 biological replicates were isolated from cardiac progenitor cells (CPCs) and endothelial populations derived from cardiogenic mesoderm (C-ECs) and hemogenic mesoderm (H-ECs). RNA-seq and ChIP-seq (H3K4me3 and H3K27me3) was performed for each replicate.

Description
Intestinal organoids are complex three-dimensional structures that mimic cell type composition and tissue organization of the intestine by recapitulating the self-organizing capacity of cell populations derived from a single stem cell. Crucial in this process is a first symmetry-breaking event, in which only a fraction of identical cells in a symmetrical cyst differentiate into Paneth cells, which in turn generates the stem cell niche and leads to asymmetric structures such as crypts and villi. We here combine a quantitative single-cell gene expression and imaging approach to characterize the development of intestinal organoids from a single cell. We show that intestinal organoid development follows a regeneration process driven by transient Yap1 activation. Cell-to-cell variability in Yap1, emerging in symmetrical cysts, initiates a Notch/Dll1 lateral inhibition event driving the symmetry-breaking event and the formation of the first Paneth cell. Our findings reveal how single cells exposed to a uniform growth-promoting environment have the intrinsic ability to generate emergent, self-organized behavior resulting in the formation of complex multicellular asymmetric structures. Overall design: Single cell RNA sequencing of single cells isolated from intestinal organoids day3 and intestinal organoids day 5
