    摘要: The present invention provides a novel method for nucleic acid amplification. The method includes contacting the sample with at least one forward primer and at least one reverse primer, an AP endonuclease, and a nucleic acid polymerase. under conditions sufficient to allow the forward and reverse primers to hybridize to the target nucleic acid and form a reaction mixture, wherein at least one of the forward and reverse primer includes an AP endonuclease-cleavable linker L, and incubating the reaction mixture under reaction conditions that simultaneously allow the AP endonuclease to cleave at a linker site L and the extension of the primers in a template-specific manner to amplify the target nucleic acid sequence.

    摘要: Methods are provided for identifying agents that modulate signaling mediated by transforming growth factor beta (TGF-β) and members of the TGF-β family, such as bone morphogenic protein (BMP). Such agents may be identified using screens that evaluate candidate agents for the ability to modulate Smad protein degradation. Agents identified as described herein may be used to augment or inhibit signaling mediated by one or more TGF-β family members in a variety of cell types and for therapeutic purposes.
