- Affymetrix Rat Genome 230 2.0 Array (rat2302)
Description
Loss of functional -cell mass is a hallmark of Type 1 and Type 2 diabetes, and methods for restoring these cells are needed. Nkx6.1 induces -cell proliferation, but the pathway by which Nkx6.1 activates -cell expansion has not been defined. Here we demonstrate that Nkx6.1 induces expression of the Nr4a1 and Nr4a3 orphan nuclear receptors, and that these factors are both necessary and sufficient for Nkx6.1-mediated -cell proliferation. Overexpression of the Nr4a receptors results in increased expression of key cell cycle inducers E2F1 and cyclin E1. Furthermore, Nr4a receptors induce components of the anaphase-promoting complex, including Ube2c.

Description
Loss of functional -cell mass is a hallmark of Type 1 and Type 2 diabetes, and methods for restoring these cells are needed. We have previously reported that overexpression of the homeodomain transcription factor Nkx6.1 in rat pancreatic islets induces -cell proliferation and enhances glucose-stimulated insulin secretion, but the pathway by which Nkx6.1 activates -cell expansion has not been defined. Here we demonstrate that Nkx6.1 induces expression of the Nr4a1 and Nr4a3 orphan nuclear receptors, and that these factors are both necessary and sufficient for Nkx6.1-mediated -cell proliferation. Consistent with this finding, global knockout of Nr4a1 results in a decrease in -cell area in neonatal and young mice. Overexpression of Nkx6.1 and the Nr4a receptors results in increased expression of key cell cycle inducers E2F1 and cyclin E1. Furthermore, Nkx6.1 and Nr4a receptors induce components of the anaphase-promoting complex, including Ube2c, resulting in degradation of the cell cycle inhibitor p21CIP1. These studies identify a new bipartite pathway for activation of -cell proliferation, suggesting several new targets for expansion of functional -cell mass.

Description
As somatic cells are converted to iPSCs, their chromatin undergoes wide-ranging rearrangements that affect the ratio of euchromatin-to-heterochromatin, DNA methylation patterns and the regulation of enhancers and promoters. The molecular machinery underlying this process remains largely unknown. Here, we show that Dppa2 and Dppa4, two thus far poorly characterized mES-specific factors, play a key role in resetting the epigenome to a pluripotent configuration. They function as a heterodimer, are induced in late reprogramming intermediates, and are required for reprogramming. When overexpressed with OSKM factors, Dppa2/4 yield reprogramming efficiencies exceeding 75% of the starting culture and accelerate reprogramming kinetics, generating iPSCs in as little as 4 days. When chromatinbound, Dppa2/4 initiate global chromatin decompaction via the DNA damage response pathway, which subsequently activates mES promoters and enhancers and enables an efficient progression to pluripotency. Our work provides critical insights into how the epigenome is remodeled during cell fate transitions.

Description
We analyzed the transcriptome of two different triple negative breast cancer (TNBC) cell lines to define a comprehensive list of Wnt target genes. Cells were treated with Wnt3a for 6h, 12h or 24h. We found up-regulated and down-regulated genes in response to Wnt3a treatment. They are involved in the Wnt pathway itself, and also in TGF, p53 and Hedgehog pathways. Thorough characterization of these novel potential Wnt target genes may reveal new regulators of the canonical Wnt pathway. The comparison of our list of Wnt target genes with those published in other cellular contexts confirms the notion that Wnt target genes are tissue-, cell line- and treatment-specific.
