Wip1 regulates Smad4 phosphorylation and inhibits TGF-β signaling.

abstract：:Short interfering RNAs (siRNAs) are short (21-23 nt) double-stranded RNAs that direct the sequence-specific degradation of corresponding mRNAs, resulting in suppression of gene activity. siRNAs are powerful tools for gene functional analysis in mammals. Chemically synthesized siRNAs permit transient gene repression bu...
