View SamplesNotch signaling defines a conserved, fundamental pathway, responsible for determination in metazoan development and is widely recognized as an essential component of lineage specific differentiation and stem cell self-renewal in many tissues including the hematopoietic system. Until recently, the majority of studies in the hematopoietic system focused on Notch signaling in lymphocyte differentiation and knowledge of individual Notch receptor roles in early hematopoiesis has been limited due to a paucity of genetic tools available To fate-map Notch receptor expression and pathway activity in the hematopoietic system we used tamoxifen-inducible CreER knock-in mice for individual Notch receptors in combination to a novel Notch reporter strain (Hes1GFP) and a conditional gain of function allele of Notch2 receptor (Rosa-lsl-ICN2).

View SamplesWhile transcriptional regulation of stem cell self-renewal and differentiation has been extensively studied, only a small number of studies have addressed the roles for post-translational modifications in these processes. A key mechanism of post-translational modification is ubiquitination by the ubiquitin-proteasome system (UPS). Using UPS-targeted RNAi screens, we identify novel regulators of pluripotency and differentiation. We focus on two of these proteins, the deubiquitinating enzyme, Psmd14, and the E3 ligase, Fbxw7, and characterize their importance in ES cell pluripotency and cellular reprogramming.

View SamplesThe cellular response to replication stress requires the DNA-damage responsive kinase ATM and its co-factor ATMIN, however the roles of this signaling pathway following replication stress are unclear. RNA-seq and subsequent differential expression analyses were utilized to identify the functions of ATM and ATMIN in response to replication stress induced by Aphidcolin (APH). Overall design: Mouse Embryonic Fibroblasts (MEFs) deleted for ATM or ATMIN were treated with 1µM APH or DMSO as a control. Two different wild-type MEF cell lines (wtATM, wtATMIN) served as controls. RNA-seq was performed in duplicates, in a total of 32 samples, with an average of 31.1M aligned readsobtained per group,with 15.5M reads obtained per replicate.
