Evaluation Of Microsatellite Polymorphism And Genetic Variability In Thai Ridgeback And Bangkaew Dogs, Janjira Phavaphutanon, Sudtisa Laopiem

The Thai Journal of Veterinary Medicine

The origin of dogs came from the limited number of founders leading to inbreeding or genetic diseasewithin or among breeds. Thai Ridgeback (TR) and Bangkaew (BK) dogs were the only native dog breeds that webelieved to originate in Thailand. The study of genetic variability in Thai dogs (39 Thai Ridgeback dogs, 82 Bangkaewdogs) was defined by using 12 microsatellite markers. These DNA markers were highly informative and distributedthrough the canine genome. The result from these markers revealed the higher number of alleles, observedheterozygosity (Ho), expected heterozygosity (He) and polymorphic information content (PIC) in TR and BK dogs.The average Ho, He …

Antagonistic Effects Of Cellular Poly(C) Binding Proteins On Vesicular Stomatitis Virus Gene Expression, Phat X. Dinh, Lalit Beura, Debasis Panda, Anshuman Das, Asit K. Pattnaik

School of Veterinary and Biomedical Sciences: Faculty Publications

Immunoprecipitation and subsequent mass spectrometry analysis of the cellular proteins from cells expressing the vesicular stomatitis virus (VSV) P protein identified the poly(C) binding protein 2 (PCBP2) as one of the P protein-interacting proteins. To investigate the role of PCBP2 in the viral life cycle, we examined the effects of depletion or overexpression of this protein on VSV growth. Small interfering RNA-mediated silencing of PCBP2 promoted VSV replication. Conversely, overexpression of PCBP2 in transfected cells suppressed VSV growth. Further studies revealed that PCBP2 negatively regulates overall viral mRNA accumulation and subsequent genome replication. Coimmunoprecipitation and immunofluorescence microscopic studies showed that …

Acute Fatty Liver Of Pregnancy: An Update On Mechanisms, Sathish Kumar Natarajan, Kavitha R. Thangaraj, Ashish Goel, C. E. Eapen, K. A. Balasubramanian, Anup Ramachandran

School of Veterinary and Biomedical Sciences: Faculty Publications

Acute fatty liver of pregnancy (AFLP), characterized by hepatic microvesicular steatosis, is a sudden catastrophic illness occurring almost exclusively in the third trimester of pregnancy. Defective fatty acid oxidation in the fetus has been shown to be associated with this disease. Since the placenta has the same genetic makeup as the fetus and as AFLP patients generally recover following delivery, we hypothesized that the placenta might be involved in pathogenesis of this disease. In an animal model of hepatic microvesicular steatosis (using sodium valproate), we found that microvesicular steatosis results in mitochondrial structural alterations and oxidative stress in subcellular organelles …

Background: Recurrent airway obstruction (RAO) is a severe chronic respiratory disease affecting horses worldwide, though mostly in the Northern hemisphere. Environmental as well as genetic factors strongly influence the course and prognosis of the disease. Research has been focused on characterization of immunologic factors contributing to inflammatory responses, on genetic linkage analysis, and, more recently, on proteomic analysis of airway secretions from affected horses. The goal of this study was to investigate the interactions between eight candidate genes previously identified in a genetic linkage study and proteins expressed in bronchoalveolar lavage fluid (BALF) collected from healthy and RAO-affected horses. The …

Effect Of The Infection With Porcine Reproductive And Respiratory Syndrome Virus On The Regulation Of Cytokines: Tumor Necrosis Factor-Alpha And Interleukin-10, Sakthivel Subramaniam

School of Veterinary and Biomedical Sciences: Dissertations, Theses, and Student Research

Porcine reproductive and respiratory syndrome virus (PRRSV) causes late-term abortion in sows and pneumonia in growing piglets. PRRSV evades the host immune response by several mechanisms, including the modulation of cytokine secretions in infected pigs, which is the subject of this dissertation. Particularly, PRRSV reduces the secretion of the pro-inflammatory cytokine, tumor necrosis factor-α (TNF-α) but increases the secretion of the anti-inflammatory cytokine interleukin-10 (IL-10). The latter effect, however, is PRRSV strain-specific. In this dissertation, we have examined mechanisms by which PRRSV regulates TNF-α and IL-10 expressions. The pathogenic strain FL12, derived from a PRRSV infectious clone, consistently suppressed TNF-α …

Role Of Porcine Reproductive And Respiratory Syndrome Virus Non-Structural Protein 1 In Viral Replications And Pathogenesis, Lalit Kumar Beura

School of Veterinary and Biomedical Sciences: Dissertations, Theses, and Student Research

Porcine reproductive and respiratory syndrome virus (PRRSV) is an infectious agent of significant concern to the global swine industry. PRRSV infection of pigs is initiated by a long viremia after which the virus enters in an extended persistent phase of 3-4 months that ultimately is resolved by the immune system. The delayed and weak host adaptive response is responsible for the protracted convalescence period. An initial sub-optimal innate immune response is postulated to be the reason behind such meager adaptive immune response. A major focus of the studies undertaken in this dissertation was to identify the viral non-structural proteins (nsps) …

Identification Of Host Proteins Required For Vesicular Stomatitis Virus Infection, Debasis Panda

School of Veterinary and Biomedical Sciences: Dissertations, Theses, and Student Research

Viruses usurp host cell pathways for different stages of their infection. Understanding virus-host interaction will be invaluable to elucidate molecular mechanisms of virus infection and to identify drug targets. In order to identify such critical cellular genes in vesicular stomatitis virus (VSV, a model non-segmented negative strand RNA virus) infection, we developed a stable cell line constitutively expressing replication proteins of VSV. Attempts to establish a cell line replicating a sub-genomic replicon was not successful because of induction of interferon response by replication of viral genomic analog. Subsequently, we used siRNA technology and conducted a genome-wide siRNA screen in HeLa …

Genes Associated With Genetic Diseases In Collies, Shetland Sheepdogs And Border Collies, Gunnaporn Suriyaphol

The Thai Journal of Veterinary Medicine

Canine genetic disorders inherited through genes or chromosomes. Mutations can also occur spontaneouslyor influenced by environmental factors. Such disorders can be transmitted to offspring. However, the disease may notbe developed owing to other influenced factors. Dominant and recessive genetic mechanisms also affect the traitoutcome. This article discussed the abnormalities of genes affected by the disease and/ or genetic disorders in Collies,Shetland sheepdogs and Border collies, sharing the Collie lineage. Most of these disorders are caused by autosomalrecessive genes. Hence, paired recessive alleles are required in order to express its phenotype. Although dogs areasymptomatic carriers, they can pass down defective genes …
