The manuscript, “Leptin protects against the development and expression of cocaine addiction-like behavior in heterogeneous stock rats”, has been accepted for publication in Frontiers in Behavioral Neuroscience. This study examines the the effect differing bodyweight and blood leptin levels on the vulnerability to addiction like behavior and the impact of exogenous leptin to cocaine seeking in a large heterogenous rat population. Dr. Abraham Palmer and current Palmer lab member, Clara Ortez, are coauthors along with several others. See pre-print here.

Congrats!

The manuscript, “A mutant allele of Neuronal Membrane Glycoprotein M6-B (Gpm6b) facilitates behavioral flexibility but increases delay discounting”, has been accepted for publication in Genes, Brain and Behavior. Authors include Sandra Sanchez-Roige, Samuel Barnes, Jazlene Mallari, Rebecca Wood, Oksana Polesskaya and Abraham Palmer.

Congratulations!

The manuscript, “A natural mutator allele shapes mutation spectrum variation in mice”, was accepted for publication in Nature. Using the BXD recombinant inbred mouse strain, this study aims to identify the loci that impacts germline mutagenesis. Natural variation in the DNA repair gene, Mutyh, was identified to possibly cause the BXD mutator phenotype. Dr. Abraham Palmer and several others are co-authors on this paper. See the manuscript here. 

Congrats, Dr. Palmer!

The manuscript, “Genome-wide association study on three behaviors tested in an open field in heterogeneous stock rats identifies multiple loci implicated in psychiatric disorders”, was accepted for publication in Frontiers Psychiatry, section Addictive Disorders. A genome-wide association study (GWAS) of behaviors measured in an open field was conducted in HS rats. 30 genome wide significant quantitative trait loci and 13 candidate genes were identified for these traits. Not only did this study identify genes that were implicated by human GWAS of psychiatry traits, but also observes several novel findings. Current

Palmer and Dulawa Lab members gathered to celebrate the holidays and Amanda’s new job as an Assistant Professor in New Mexico! Happy Holidays!

Dr. Amanda Barkley-Levenson has accepted a position as an Assistant Professor in the Department of Pharmaceutical Sciences at the University of New Mexico Health Sciences Center and will be starting in 2022. Her lab will work on understanding the genetic basis of alcohol use disorder and excessive drinking by translating novel hits from human GWAS into mouse models for comprehensive follow-up and validation.

Congratulations, Amanda!

Gabe Barrero joined the Palmer lab in November 2021 as an information system analyst with a Bachelor of arts in Biology. He is passionate about data science and its application in international development. In his free time Gabe enjoys Brazilian Jiu Jitsu, Muay Thai, biking, cooking and ice cream.

Welcome, Gabe!

The article, “Polygenic transcriptome risk scores (PTRS) can improve portability of polygenic risk scores across ancestries”, has recently been accepted for publication in Genome Biology. This study explores the use of polygenic transcriptome risk scores (PTRS) to improve the prediction of transcriptomic data in underrepresented populations. Dr. Abraham Palmer and several others coauthored this article. See the article here. Congratulations, Dr. Palmer!

The article, “Genes identified in rodent studies of alcohol intake are enriched for heritability of human substance use”, has been accepted for publication in Alcoholism: Clinical and Experimental Research. This article discusses the use of GeneWeaver to enrich rodent alcohol & nicotine gene-sets for heritability of substance use traits in humans. Dr. Abraham Palmer and several others coauthored this article. See article here. Congratulations!
