The intestine plays a central role in digestion, nutrient absorption and metabolism, with individual regions of the intestine having distinct functional roles. Many examples of region-specific gene expression in the adult intestine are known, but how intestinal regional identity is established during development is a largely unresolved issue. Here, we have(More)
BACKGROUND & AIMS The Lgr family of transmembrane proteins (Lgr4, 5, 6) act as functional receptors for R-spondin proteins (Rspo 1, 2, 3, 4), and potentiate Wnt signaling in different contexts. Lgr5 is arguably the best characterized of the Lgr family members in a number of adult and embryonic contexts in mice. However, the function of LGR family members in(More)
Nucleobase analogs 5-methylisocytosine ((Me)isoC) and isoguanine (isoG) form a non-natural base pair in duplex nucleic acids with base pairing specificity orthogonal to the natural nucleobase pairs. Sequencing reactions were conducted with oligodeoxyribonucleotides (ODNs) containing d(Me)isoC and disoG using modified pyrosequencing and dye terminator(More)
