Epithelial tumors secrete the ER-resident AGR2 in the extracellular matrix to function as a novel essential microenvironmental regulator of epithelial tissue architecture, which leads to tumorigenicity.
Genetic and biochemical analyses reveal that two stem-cell-specific microRNAs control stem cell fate decisions between pluripotency and differentiation through repressing Ago2, a key component of the microRNA machinery.
The central RNA interference protein, human Argonaute-2, releases its target following phosphorylation on a critical loop in the protein, freeing microRNA-bound Argonaute-2 to seek out and repress additional targets.
In transgenesis assays involving diploid model organisms, two clearly distinguishable transformation markers embedded in interweaved, but incompatible Lox site pairs allow the systematic creation of homozygous transgenic lines and minimize the number of wasted animals.

A single microRNA-binding site in a long non-coding RNA alters T cell responses in vivo by 'sponging' the miRNA to inhibit its gene regulatory function.
