MicroRNAs (miRNAs) are small non-coding RNA molecules which function as negative gene regulators. The tissue expression profile of miRNAs shows great promise as a novel biomarker for diagnosis of cancer and other diseases. In addition, some recent reports have demonstrated that are present in human ...

Supercritical rosemary extract (containing 16.90% carnosic acid, 1.90% carnosol and 13.59% volatile compounds) showed antitumor activity on colon cancer cells in vitro. We treated colon cancer cells with the extract and we employed whole genome microarray expression profiling to identify genes poten...

The guanosine triphosphatases of the Rho and Rac subfamilies regulate protumorigenic pathways and are activated by guanine nucleotide exchange factors (Rho GEFs), which could be potential targets for anticancer therapies. We report that two Rho GEFs, Vav2 and Vav3, play synergistic roles in breast c...

Mitogen-activated dual-specificity MAPK phosphatases are important negative regulators in the MAPK signalling pathways responsible for many essential processes in plants. In a screen for mutants with reduced organ size we have identified a mutation in the active site of the dual-specificity MAPK ph...
