An ancient complex comprising the eukaryotic elongation factor-1A and aminoacylated tRNA is shown to be the target of a cyclic heptapeptide and two unrelated natural products with potent anticancer activity.
Eukaryotic translation elongation factor 1A1 controls the process of heat shock response, from transcriptional activation of the HSP70 gene, to HSP70 mRNA stabilization, nuclear export, and translation.
The sigma subunit of bacterial RNA polymerase, classically known as an initiation factor, can also operate as an elongation factor with effects that vary with growth phase.

A comprehensive analysis of the glucocorticoid-sensitive pro-inflammatory genes in macrophages reveals fundamental differences between the temporal events and components of transcriptional machinery that the glucocorticoid receptor targets to repress their transcription.

The spatial-temporal computer model of plant root meristem combines biomechanics and biochemical scales to reveal design principles underlying cell polarity and anisotropic growth during root development.
During initiation factor-independent RNA structure-driven translation initiation, a flexible RNA element drives the movement of a viral IRES through the ribosome's tRNA binding sites and promotes tRNA binding.
Activation of the stress response pathway in young cells extends replicative lifespan, not by reducing global protein synthesis per se, but by Gcn4-mediated autophagy induction.

Structure-function analysis of the super elongation complex formed when HIV replicates inside cells reveals that the HIV-1 Tat protein binds to a cleft between P-TEFb, an enzyme that is involved in normal transcription, and AFF4, a protein that is used to build the super elongation complex
