Cell migration is an integral part of re-epithelialization during skin wound healing, a complex process involving molecular controls that are still largely unknown. Here we identify a novel role for Tcf3, an essential transcription factor regulating embryonic and adult skin stem cell functions, as a key effector of epidermal wound repair. We show that Tcf3(More)
In this study, it was found that the arrangement of consecutive thiocarbonyl groups of s(2)T and m(5)s(2)C remarkably stabilized the pre-protonated form of the triplex, and that the stabilization of the pre-protonated form increased the pKa value of a cytosine derivative in the triplex.
In this paper, we report DNA and 2'-OMe-RNA probes containing 5-methyl-2-thiocytidine (m(5)s(2)C) residues that can bind selectively and strongly to the corresponding RNA targets containing inosine residues by the significant stacking effect and steric hindrance of the 2-thiocarbonyl group.
Amidine-type protecting groups, i.e., N,N-dimethylformamidine (dmf) and N,N-dibutylformamidine (dbf) groups, introduced into nucleobases were rapidly removed under mild acidic conditions using imidazolium triflate (IMT) or 1-hydroxybenztriazole (HOBt). This new deprotection strategy allowed a 2'-O-methyl-RNA derivative bearing a base-labile group to be(More)
Trivalent phosphoramidite derivatives could be readily converted by reacting with 1-hydroxy-7-azabenzotriazole to phosphotriester intermediates; these intermediates reacted smoothly with phosphorylated compounds to give pyrophosphate derivatives. This new phosphorylation approach enabled a facile and rapid synthesis of 5'-adenylated DNA oligomers(More)
