BookPublisher: 2017Description: 107p.Subject(s): Molecular Biology and BiotechnologyDDC classification: 2939-T Dissertation note: In the biosynthetic pathway for brain serotonin, Tryptophan hydroxylase-2 (TPH2) acts as the rate-limiting enzyme. It is a key element in maintaining adequate serotonin neurotransmission in the central neuron system (CNS). It is broadly discussed as an important candidate gene in multiple psychiatric disorders, especially suicidal behavior and depression. A relationship between TPH2 and major depressive disorder (MDD) has been reported by multiple gene-disease association studies in different populations. Horse can be employed as a valuable candidate for an animal model of depression because it shares environmental factors which are known to cause depression in humans.The hypothesis of this study was that, there is association between TPH2 gene polymorphisms and risk of developing MDD.Blood was collected from each participant.Human (Experimental and Control group) and Horse (Experimental and Control group).DNA wasextracted usingthe standard Phenol Chloroform Isoamyl alcohol (PCI) protocol. Specific set of primers were designed for the amplification of TPH2 gene exons and partial region of the introns. The amplified PCR products was precipitated and sequenced for the identification of variants. For sequence data analysis Chromas Software(2.1) was used along with BLAST available at NCBI and Clustal W program. Multiple alignments were performed for polymorphism identification and association of identified polymorphisms was performed using SPSS.The significant association of the variant rs7305155 with Major Depressive Disorder indicates that TPH2 has a role in disease etiology.Understanding the extent of the role different genes play in MDDmay help in tailoring medication. “Gene-Response to drug” association studies have also shown that patients with certain polymorphisms might respond better to certain class of drugs. It is useful to know which variants are prevalent in our population.
