Mechanistic investigations revealed that RASSF1A blocked tumor growth by stimulating cofilin / PP2A - mediated dephosphorylation of the guanine nucleotide exchange factor GEF - H1, thereby stimulating its ability to activate the antimetastatic small GTPase RhoB. (science.institut-curie.org)
The Oligonucleotide Directed Mutagenesis (ODM) as Targeted Nucleotide Exchange (TNE) by single stranded DNA oligonucleotides (SDOs) attracts special attention for use in both basic science and plant breeding. (brc.hu)
