BookPublisher: 2017Description: 93p.Subject(s): Forensic SciencesDDC classification: 2901-T Dissertation note: Behavior that is directed to injure living beings and damage their neuroconductual processes without any incitement, represents the aggressive behavior. COMT gene is of much importance in determining violent act in both animal and human.The present study is designed to molecular characterize the gene with following objective: to screen out polymorphism (SNPs) in exonic region of COMT gene in cats and tiger and to associate the identified polymorphism in cats and tiger. Aggression questionnaire was filled by honors of all domestic and wild cats included in our study.Blood sample of 5 Stray cat, 5 Persian cat and 5 Siamese cat and 5 Bengal tigers were collected from Lahore Zoo, UVAS PET Centre, Private Pet Clinics and Safari Zoo Lahore for SNP analysis. DNA were extracted from blood by organic method, 5 sets of primers were designed by primer 3 software for the amplification of the COMT genes. The amplified PCR products were precipitated and sequenced bi-directionally on ABI 3130XL Genetic analyzer, for the identification of SNPs.Alignment of sequences were done with the help of blast2 sequences. For sequence data analysis, Bioedit and Clustal W were used to complete the study.Results of sequencing were analyzed using BioEdit software. Sequence alignment tool like Clustal W was used for SNPs identification. 3 intronic and 1 exonic SNPs were observed and confirmed by Clustal W. Exonic SNP was linked to aggression. However, intronic SNPs were not found to be associated with self-reported aggression. SNP observed in exon 2 is reported to be involved in psychiatric and depressive disorders.Our study highlighted the role of COMTgene polymorphisms in aggression in animals (Cats and tiger). Different breeding Policies and Pet plains are now working and we can screen out the susceptibility of aggression in cats and tiger.
