Project description:We sequenced total RNA from whole blood samples of 27 wild gray wolves from Yellowstone National Park. Gene expression level analysis of both male and female wolves, ranging from ages 0.8-8.8 years.
Project description:The goal of the study was to test whether CBD103 genotype of North American gray wolves impacts the gene expression response to polyI:C or to live canine distemper virus. We established 24 primary cultures of epidermal keratinocytes from skin punches of North American gray wolves, and also generated an immortalized keratinocyte line and a CRISPR/Cas9 edited cell line. We evaluated the gene expression response of cells to either 24 hours challenge with 1 ug/ml polyI:C or to five days challenge with live canine distemper virus (100 TCID50/ml). Every challenged cell culture had a paired null control sample (plated and collected at same time points).
Project description:This study uses a custom made Nimblegen aCGH chip that targeted all segmental duplications in the canine genome to identify associated CNVs. A total of 23 hybridizations were performed in a panel of diverse dogs and a single wolf. This study focuses on the use a custom made Nimblegen aCGH chip to genotype 1,611 dog CNVs in 23 wolf-like canids (4 purebred dogs, one dingo, 15 gray wolves, one red wolf, one coyote and one golden jackal) to identify CNVs that may have arisen after domestication
Project description:Through thousands of years of breeding and strong human selection, the dog (Canis lupus familiaris) exists today within hundreds of closed populations throughout the world, each with defined phenotypes. A singular geographic region with broad diversity in dog breeds presents an interesting opportunity to observe potential mechanisms of breed formation. Italy claims 14 internationally recognized dog breeds, with numerous additional local varieties. To determine the relationship among Italian dog populations, we integrated genetic data from 263 dogs representing 23 closed dog populations from Italy, seven Apennine gray wolves. Using 142,840 genome-wide SNPs, this dataset was used in the identification of breed development routes for the Italian breeds that included divergence from common populations for a specific purpose, admixture of regional stock with that from other regions, and isolated selection of local stock with specific attributes.

Project description:De novo mutation rate estimation in Yellowstone gray wolves
Project description:Diverse dataset of 1247 dogs from many breeds and wolves used to investigate the origins of dog domestication DNA for 1228 dogs from 35 breeds and 19 wolves was extracted from whole blood samples and genotyped on the Affymetrix Canine v2 Arrays. Genotypes were called using Affymetrix's snp5-probeset-genotype software and the BRLMM-P calling algorithm. The included breed designations are owner reported.
