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.

Incentive Salience, not Psychomotor Sensitization or Tolerance, Drives Escalation of Cocaine Self-Administration in Heterogeneous Stock Rats

Jarryd Ramborger, Joseph Mosquera, Molly Brennan, Benjamin C. Sichel, Dyar N. Othman, Sonja Lorean Plasil, Elizabeth A. Sneddon, Sélène Bonnet-Zahedi, Alex Morgan, Supakorn Chonwattanagul, Kathleen Bai, Lindsey China, Tu La, Lisa Maturin, Lieselot L. G. Carrette, Olivier George

The paper identifies incentive salience as the driver of cocaine self-administration escalation in rats, showing individual differences in pre-lever activity predict long-term intake.

Sex-specific transcriptional signatures of oxycodone persist during withdrawal and abstinence in the suprachiasmatic nucleus of heterogeneous stock rats

Tara C. Delorme, Snehal Sambare, Benjamin R. Williams, Mackenzie C. Gamble, Lieselot L.G. Carrette, Leah C Solberg Woods, Lisa Maturin, Abraham A. Palmer, Olivier George, Ryan W. Logan

This study identifies sex-specific transcriptional changes in the SCN of rats during oxycodone withdrawal and abstinence, linking these changes to addiction-related behaviors.

Addiction Neuroscience · Dec 1, 2025Peer-reviewedNeuroscience

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.
