The eEF1γ subunit contacts RNA polymerase II and binds vimentin promoter region.

Here, we show that the eukaryotic translation elongation factor 1 gamma (eEF1γ) physically interacts with the RNA polymerase II (pol II) core subunit 3 (RPB3), both in isolation and in the context of the holo-enzyme. Importantly, eEF1γ has been recently shown to bind Vimentin mRNA. By chromatin immunoprecipitation experiments, we demonstrate, for the first time, that eEF1γ is also physically present on the genomic locus corresponding to the promoter region of human Vimentin gene.

RISC activity in hippocampus is essential for contextual memory.

RNA-Induced Silencing Complex (RISC) mediates post-transcriptional control of gene expression and contains Argonaute 2 (AGO2) protein as a central effector of cleavage or inhibition of mRNA translation. In the brain, the RISC pathway is involved in neuronal functions, such as synaptic development and local protein synthesis, which are potentially critical for memory. In this study, we examined the role of RISC in memory formation in rodents, by silencing AGO2 expression in dorsal hippocampus of C57BL/6 mice and submitting animals to hippocampus-related tasks.

The artificial gene Jazz, a transcriptional regulator of utrophin, corrects the dystrophic pathology in mdx mice.

The absence of the cytoskeletal protein dystrophin results in Duchenne muscular dystrophy (DMD). The utrophin protein is the best candidate for dystrophin replacement in DMD patients. To obtain therapeutic levels of utrophin expression in dystrophic muscle, we developed an alternative strategy based on the use of artificial zinc finger transcription factors (ZF ATFs).
