Multi-species study reveals new insights into OCD
Canine OCD normally manifests as excessive licking, sucking, or tail chasing.

Researchers identify new genes associated with the disorder

A study by US scientists has revealed new insights into the genetics underlying obsessive-compulsive disorder (OCD) in humans and animals.

Researchers at the Broad Institute, Massachusetts, compared genetic information across multiple species that suffer from compulsive behaviour disorders and found four new genes with OCD-variants in humans.

The genes are thought to disrupt synapse development and throw neural pathways in the brain out of balance. The data is published in the journal Nature Communications.

OCD is a mental health disorder that affects some 80 million people worldwide. Obtained by inheritance, the biology of the disorder is still poorly understood.

To better understand the disorder, the team compiled a list of genetic associations from previous studies of human and animal OCD. The team used the data to refine a list of more than 600 genes and 80,000 related regulatory elements that might be involved in human OCD.

As part of the study, the researchers assessed genetic studies of canine OCD, which normally manifests as excessive licking, sucking, or tail chasing.

“We were seeking ways to take advantage of information from other species in order to inform and focus the study in humans,” explained study author Hyun Ji Noh. “Each additional species that we looked at gave us more information about possible factors in the brain that contribute to OCD.”

The four genes identified by the team - NRXN1, HTR2A, CTTNBP2 and REEP3 - all showed variants in either protein-coding or regulatory DNA significantly associated with human OCD.

Researchers say the data suggest new targets to pursue an improved biological and therapeutic understanding of OCD.

New online dental resource for vets and horse owners

News Story 1
 The British Equine Veterinary Association (BEVA) has launched a new online dental resource for vets and horse owners.

The veterinary section of the resource is aimed at primary practice equine vets who are performing dentals for clients as part of a routine care programme. Information includes 'how to perform a thorough oral exam,' guidelines for charting, and a list of BEVA equine vets with postgraduate qualifications in equine dentistry.

Free to BEVA members, the new resource is supported by a range of practical courses, veterinary CPD, workshops and webinars. To find out more visit the BEVA website

Vet school runs event for aspiring vets and nurses

Bristol Veterinary School is hosting an event for aspiring vets and vet nurses, to allow them to experience life as a student and find out what itís like to work in veterinary medicine. The one-day event, called VetQuest, will be held at the Langford Campus and includes a tour, talks on admissions and work experience, and the chance to take part in practical sessions. Taking place on Saturday 27 October, the event is primarily aimed at 11-12 year olds and costs £50, including lunch. There are a limited number of subsidised tickets for £10.
