There was no complex coloration or shadowing to his art, it was just seven simple glyphs, thrown up all over the city in small, but persistent expressions of identity.
RARγ1 knockdown obliterates somite boundaries, and causes loss of Myod protein in the presomitic mesoderm, but ectopic, persistent expression of Myod protein in the trunk.
However, despite the viability and evident three-dimensional epidermis-like growth pattern, hMSC showed a persistent expression of mesenchymal but not of epithelial markers, thus indicating a lack of epidermal (trans) differentiation.
This suggests a persistent expression of mutant but non-functional Na+ channels despite the complete abolition of Na+ currents in the homozygote, consistent with a continued expression of non-functional channels rather than a total failure of expression of otherwise normal channels.
Currently, two challenges to the eradication of infection are apparent: the persistence of latent infection, and the persistent expression of low levels of virions from cells infected prior to ART initiation.
These findings indicate that persistent expression of wild type Smac56, but not Smac60, in the cytosol of 911 cells essentially abolished its ability to oligomerize.
The overlapping function of Neurod1 and Nhlh1 may not only lead to the survival of some neurons but the absence of Neurod1 may allow premature and persistent expression of Atoh1 in these remaining ganglion neurons (Fig. 2D, D').
The residual expression of Lpcat3 mRNA in the liver of Lpcat3 KO mice was likely due to persistent expression of Lpcat3 in cell types that do not express the albumin-Cre transgene (Kupffer cells, endothelial cells).
Isolated groups of Foxa2-expressing cells embedded in Foxa2-negative epithelium displayed persistent expression of ZO-1 (data not shown) and ZO-2 (Fig. 7C,D), demonstrating that the observed effect is specific and cell autonomous.
The ligand for CXCR4, stromal-derived factor-1 (SDF-1), is expressed on synovial endothelial cells [ 44], and persistent expression of the chemokine receptor CXCR4 on synovial CD4 T cells mediates their active retention within the rheumatoid synovium [ 45].
