英文摘要
Processing bodies(P-bodies) contain a common set of conserved RNA-processing enzymes, and mRNAs with AU-rich elements(AREs) are delivered to P-bodies for translational silencing. It is unclear how small GTPases are involved in the P-body regulation and the ARE-mRNA metabolism. We found here that overexpression of the RhoA-subfamily GTPases alters the P-body dynamics in HeLa cells. Interestingly, both RhoA activation and glucose depletion inhibit the mRNA accumulation and degradation. These findings indicate that RhoA participates in the stress-induced rearrangement of P-bodies and the release of nucleated ARE-mRNAs for their stabilization.
