Summary of "Reward activation in childhood predicts adolescent substance use initiation in a high-risk sample."

Substance use at an early age conveys substantial risk for later substance-related problems. A better understanding of early risk factors could result in more timely and effective intervention. This study investigated the predictive utility of the brain's response to reward anticipation as a risk factor for early substance use initiation.

Medical and Biotech [MESH] Definitions

A eukaryotic initiation factor that binds to 40S ribosomal subunits. Although initially considered a "non-essential" factor for eukaryotic transcription initiation, eukaryotic initiation factor-1 is now thought to play an important role in localizing RIBOSOMES at the initiation codon of MRNA.

A component of eukaryotic initiation factor-4F that is involved in multiple protein interactions at the site of translation initiation. Thus it may serve a role in bringing together various initiation factors at the site of translation initiation.

A trimeric peptide initiation factor complex that associates with the 5' MRNA cap structure of RNA (RNA CAPS) and plays an essential role in MRNA TRANSLATION. It is composed of EUKARYOTIC INITIATION FACTOR-4A; EUKARYOTIC INITIATION FACTOR-4E; and EUKARYOTIC INITIATION FACTOR-4G.

Any observable response or action of an adolescent.

A eukaryotic initiation factor that interacts with the 40S initiation complex and promotes the hydrolysis of the bound GTP. The hydrolysis of GTP causes the release of EUKARYOTIC INITIATION FACTOR-2 and EUKARYOTIC INITIATION FACTOR-3 from the 40S subunit and the subsequent joining of the 60S ribosomal subunit to the 40S complex to form the functional 80S initiation complex
