Genome-wide association study of cocaine self-administration behavior in Heterogeneous Stock rats

Montana Kay Lara, Lieselot L. G. Carrette, Thiago Missfeldt Sanches, Oksana Polesskaya, Alicia Avelar, Angela Beeson, Hassiba Beldjoud, Brent Boomhower, Molly Brennan, Denghui Chen, Riyan Cheng, Lindsey China, Apurva S. Chitre, Dana Conlisk, McKenzie J. Fannon, , Olivier George

This study performs a GWAS on cocaine self-administration in rats, identifying six genome-wide significant loci, including one linked to carboxylesterase genes involved in cocaine metabolism.

Large-scale characterization of cocaine addiction-like behaviors reveals that escalation of intake, aversion-resistant responding, and breaking-points are highly correlated measures of the same construct.

Giordano de Guglielmo, Lieselot L. G. Carrette, Marsida Kallupi, Molly Brennan, Brent Boomhower, Lisa Maturin, Dana Conlisk, Sharona Sedighim, Lani Tieu, McKenzie J. Fannon, Angelica R. Martinez, Nathan Velarde, Dyar N. Othman, Benjamin C. Sichel, Jarryd Ramborger, , Olivier George

The paper shows that escalation of cocaine intake, progressive ratio responding, and continued use despite adverse consequences are highly correlated in rats, with sex differences in addiction-like behaviors.

Dynorphin counteracts orexin in the paraventricular nucleus of the thalamus: cellular and behavioral evidence

Alessandra Matzeu, Marsida Kallupi, Olivier George, Paul Schweitzer, Rémi Martin‐Fardon

This study shows that dynorphin in the paraventricular nucleus of the thalamus counteracts orexin's effect on cocaine-seeking behavior by reducing glutamate release.
