  • Inhibition of Brd4:histone H4 interaction by the BET domain inhibitor (+)-JQ1 in ESCs results in enhanced differentiation to the endodermal lineage, by disrupting the protein abundance dynamics. (biomedcentral.com)
  • Together, our data demonstrate the fundamental role of Brd4 in monitoring cell differentiation through its interaction with acetylated histone marks and disruption of Brd4 may cause aberrant differentiation. (biomedcentral.com)
  • The differential medical diagnosis of PLNP and nodal marginal area lymphoma (MZL) with comprehensive plasmacytic differentiation is certainly tough. (irpa2006europe.com)
  • Here we review single gene disorders that have the potential to mimic multiple sclerosis, provide an overview of clinical and investigational characteristics of each disorder, and present guidelines for when clinicians should suspect an underlying heritable disorder that requires diagnostic confirmation in a patient with a definite or probable diagnosis of multiple sclerosis. (medscape.com)
  • Here, we have revealed the role of viral FLICE-inhibitory protein (vFLIP) in the initiation of PEL and MCD by specifically expressing vFLIP at different stages of B cell differentiation in vivo. (jci.org)
  • Our final student worked to introduce a "suicide gene" construct into engineered in iPSCs for the generation of the insulin-producing -cell to treat type 1 diabetes patients. (ca.gov)
  • It remains difficult to introduce defined changes and to achieve complete differentiation of iPSCs into for example sensory neurons (SNs). (ngn-pet.com)
