Project description:The Tasmanian devil, a marsupial carnivore, is endangered due to the emergence of a clonally transmissible cancer known as Devil Facial Tumor Disease (DFTD). This fatal cancer is clonally derived and is an allograft transmitted between devils by biting. We performed a large-scale genetic analysis of DFTD with microsatellite genotyping, mitochondrial genome analysis, as well as deep sequencing of the DFTD transcriptome and miRNAs. These studies confirm that DFTD is a monophyletic clonally transmissible tumor, and suggest that the disease is of Schwann cell origin. On the basis of these results we have generated a diagnostic marker for DFTD, and identify a suite of genes of relevance to DFTD pathology and transmission. We provide a genomic dataset for the Tasmanian devil, which is applicable to cancer diagnosis, disease evolution and conservation biology. This submission contains only small RNA sequence data from this study.

Project description:The canine transmissible veneral tumour (CTVT) is one of the few known clonally transmissible cancers in nature. CTVT regresses spontaneously or after a single treatment with vincristine, however we know little of the mechanisms. To understand CTVT regression, we performed transcriptional analyses on serial biopsies of regressing and non-regressing CTVT, aiming to identify the likely drivers of CTVT regression.

Project description:The canine transmissible veneral tumour (CTVT) is one of the few known clonally transmissible cancers in nature. CTVT regresses spontaneously or after a single treatment with vincristine, however we know little of the mechanisms. To understand CTVT regression, we performed methylome analyses on serial biopsies of regressing and non-regressing CTVT, aiming to identify the likely drivers of CTVT regression.

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:In this study, beta-TCP was implanted in dog mandibles, after which the gene expression profiles and signaling pathways were monitored using microarray and Ingenuity Pathways Analysis (IPA). Following the extraction of premolars and subsequent bone healing, betaâTCP was implanted into the artificial osseous defect. Total RNA was isolated from bone tissues and gene expression profiles were examined using microarray analysis. We used microarrays to detail the global programme of gene expression and identified distinct classes of up- and down- regulated genes during this process. Waiting 3 months healing after tooth extraction from beagle dog mandibles, we drilled the holes in the dog mandibles, and implanted without and with beta-TCP. And these dog mandibles were selected for RNA extraction and hybridization on Affymetrix microarrays. After implanting beta-TCP in the dog mandibles 4, 7, 14 days, we selected sample at 3 time points: Control_4d, beta-TCP_4d, Control_7d, beta-TCP_7d, Control_14d, beta-TCP_14d.

Project description:Whole genome sequencing of CTVT, breed dogs, and wild canids reveals pathways that are important in cancer cell survival. Comparison of these mutations with breed dogs shows that the original tumor came from a dog very similar to one of the modern Arctic breeds.
