2007 Canine Health Foundation National Parent Club Canine Health Conference St. Louis, Missouri October 19-21, 2007 Proceedings and Summary
The Story So Far • Founded in 1995 • Seventh biennial Parent Club Conference • More than $20 million in research grants • More than 2,000 researchers from Netherlands to California The Canine Health Foundation
The Story So Far • American Kennel Club • Nestlé Purina PetCare Company • Canine Health Information Center (CHIC) • Orthopedic Foundation for Animals Alliances Make It Happen
The Story So Far • Mission: To develop significant resources for basic and applied health programs with emphasis on canine genetics to improve the quality of life for dogs and their owners. The Canine Health Foundation
The Story So Far • OAK grants • $12,000 to $250,000 in value + 8% overhead • Assessed annually and peer reviewed • $1.8 million in annual funding • ACORN grants • Maximum $12,000 + 8% indirect costs • More than 100 approved • $400,000 annual budget Two funding categories
The Story So Far • Prevention • 78% of major grant money • Includes genomics research • Treatment • 13% of grant money • Cure • Stem cell treatments to reverse the effects of disease Three areas of research
The Story So Far • “…Don’t eradicate good dogs from your breeding programs because they’re carriers…But that means knowing who is and who isn’t a carrier.” Basic prevention principle
The Story So Far • Genetically, dogs and humans are about 85% similar • Breeding practises are responsible for many canine diseases • Research on Dobermans with narcolepsy has led to tests of a therapy that, if effective in dogs, could help 250,000 Americans The human/canine connection
Genetics primer The Story So Far • Phenotype is an animal’s appearance • Genotype is its genetic characteristics • The genotype is determined by animal’s DNA • Genes are regions on a DNA strand that govern the specifics of the genotype, like hair length • DNA strands are made of nucleotide bases that combine to form the template of a gene
Genetics primer cont’d The Story So Far • Canines have more than two billion nucleotide bases, and 20,000 unique genes, packaged in 76 DNA regions called chromosomes • Chromosomes come in pairs • Within the chromosomes, the two copies of each gene are called alleles • Each pair of genes is called a diploid, and each is responsible for a specific trait, like hair color
Alleles The Story So Far • Dogs have two alleles in each chromosomal pair • Alleles can be identical or different, dominant or recessive • In meiosis, a puppy receives one randomly selected allele from the pair of each of its parents, forming a new combination
Prevention • There are about 400 domestic dog breeds, from 100-1,000 years old • Comparison of distantly related breeds that share a disease but little genetic information can reveal the most likely genetic source of the disease • Population studies allow researchers to learn a great deal from just one generation Breeds and genetic study
Recommendations for healthy breeds Prevention • Breed away from harmful alleles, before breeding for diversity • Overuse of one sire spreads harmful genes and eliminates positive ones from other good dogs • Genetic disease is controlled by reducing the frequency of dogs with defective genes • Genetic diversity is breeder diversity; we need a healthy range of opinions on the ideal dog
Prevention • Strategies to encourage or discourage particular traits in dogs: • Inbreeding • Line breeding • Phenotypic breeding • Outcross breeding • Compensatory breeding Approaches to breeding
Prevention • Samples are the key to research • A central tissue sample repository will advance research rapidly • Collection sites are already established at: • Ohio State University • Colorado State University • University of Wisconsin-Madison Canine Oncology and Genomics Consortium
Prevention • Spaying and neutering prevent overpopulation • 56% of litters are unplanned • Neutering males reduces the risk of some diseases, increases the incidence of cruciate ligament injury • Spaying females reduces common, frequently fatal diseases, but increases the frequency of urinary incontinence Canine reproduction
Prevention • Immunity is part innate, part acquired • The acquired immune system remembers every antigen or organism it encounters • Vaccines stimulate the acquired immune system Canine vaccination
Prevention • Infectious vaccines: • Modified live vaccine • Vector vaccine • Non-infectious vaccines: • Inactivated or killed vaccine • Recombinant subunit vaccine Canine vaccination cont’d
Canine Influenza Virus (CIV) West Nile Virus Leishmaniasis Treatment Infectious disease • Rabies • Intestinal Parasites • Brucellosis • Tularemia • Leptospirosis
Treatment • CHF is helping to fund research projects for two eye diseases: • Ocular melanosis in Cairn Terriers • Progressive retinal atrophy (PRA) Canine ophthalmology
Treatment • Signs that arthritis may cause canine cruciate rupture: • Roughening at edges of bone • Excess fluid within joint • Inflammatory cells in joint fluid • Bacteria present in many affected dogs Cruciate rupture and arthritis
Treatment • A genetic test for PHPT was successfully developed thanks to: • Samples from a variety of owners • Funding from CHF • Availability of technology Hyperparathyroidism in Keeshonds
Nutritional Treatment • Four stages of intervention: • Basic feeding of a complete, balanced diet • Adding nutrients like vitamin D, copper, selenium • Adding probiotics and whey protein • Tailoring the diet to the dog’s individual needs Nutrition and the immune system
Nutritional Treatment • Positive components in an active dog’s diet: • High fat • High protein • Antioxidants • Glucosamine • Omega-3 fatty acids Nutrition for the active dog
Nutritional Treatment • Good bacteria help the body by: • Improving overall nutrition • Promoting a healthy immune system • Helping to treat diarrhea Benefits of a balanced GI tract
Closing in on a Cure • Stem cell research is being conducted for such diverse conditions as • Dilated cardiomyopathy (DCM) • Spinal cord injuries • Idiopathic pulmonary fibrosis (IPF) • Lipoprotein lipase (LPL) deficiency Cytotherapeutics
Closing in on a Cure • Adult stem cells exist in bone marrow, the liver, and the heart • Bone marrow stem cells have the potential to become nervous tissue, bone, or heart muscle • Tests show that stem cells injected into the heart remain there Cardiology and stem cells
Closing in on a Cure • Existence of cancer stem cells has been demonstrated • Cancer stem cells can self-renew, reproduce • Mutated stem cells may resist therapy, then metastasize • Better knowledge may lead to treatment Canine cancer and stem cells
Closing in on a Cure • Golden Retrievers have… • A high rate of cancer • Predominance of specific cancers • A high rate of immune-mediated diseases • … indicating an inherited disposition for cancer. Cancer at the breed level
Closing in on a Cure • FACT: Even incurable cancers can be treated or managed • FACT:A “wait and see” attitude leads to tumors that are larger and likely to spread • FACT: Chemotherapy has few side effects and risks • FACT: Age is not a factor in treatment • FACT: Radiation rarely has side effects Responding to canine cancer myths
Closing in on a Cure • Much to learn about the effect of stem cells on cancer • Research funding is weighted toward prevention • Support of dog owners is needed Are we ready for cytotherapeutics?
