Molecular Exploration Of Zbed6 Gene For Growth Trait In Lohi Sheep

by Usman Sagheer (2014-VA-03) | Dr. Maryam Javed | Dr. Akhtar Ali | Prof. Dr. Tahir Yaqub.

Material type: book Book; Literary form: not fiction Publisher: 2016Dissertation note: ZBED6 gene is a central transcription factor. It is as a repressor of IGF2 (insulin-like growth factor II) interpretation in skeletal muscle myogenesis and development. It is essentially included in organism development, signaling, cell to cell collaboration, hepatic fibrosis, clathrin intervened endocytosis and tight intersection signaling falls. Chromatin immune precipitation (ChIP) sequencing utilizing C2C12 cells recognized around 2,500 ZBED6 binding locations in the genome, and the derived accord theme gave an immaculate match with the set up tying site in IGF2. Silencing of ZBED6 in myoblast cells influences IGF2 expression, wound healing, cell proliferation and myotube arrangement. Genes connected with ZBED6 binding sites demonstrated a very huge advancement for certain Gene Ontology groupings, including improvement and transcriptional regulation. Forty two blood samples were collected. DNA extraction was done by using organic extraction method. Primers for PCR amplification designed using Primer3 software. PCR products were sequenced and then analyzed by using BioEdit software. Expasy translational tool for translation and POPGENE 32 software for analysis of population genetics at all the loci were used. Using this software the overall allele frequency, heterozygosity, probability using Chi-square test and Likelihood ratio test and Hardy-Weinberg equilibrium, genotype distribution at all SNP position, summary of genetic variation statistics for all loci and association were calculated. After this, for the association one way ANOVA was performed. Single nucleotide polymorphism within ZBED6 could be potential candidate gene to be serving as genetic marker for the selection of animals with higher tendencies towards weight gain.

Development Of Novel mtDNA Metabarcodes For Species Differentiation Of Class Mammalia

by Rabia Latif (2014-VA-952) | Dr. Muhammad Imran | Dr. Saadat Ali | Dr. Akhtar Ali.

Material type: book Book; Literary form: not fiction Publisher: 2016Dissertation note: The Folmer COI mtDNA universal primers that are considered standard for DNA barcoding of life contain so many mismatches against the target sequences of vertebrate origin that they often end in failure to amplify many of vertebrate DNA extractions. This discrepancy favors for the selection and designing of new metabarcode primers that can be used to identify all individuals of vertebrates or at least all individuals represented in a class of Vrtebrata such as Class Mammalia. The current study embarks on such an endeavor. In this study development of new mtDNA metabarcode (16SrRNA) that can be used as universal primers to amplify almost all species of Class Mammals for different forensic and molecular biodiversity analyses. Mitochondrion, the energy coins for the cell, performs the function of the oxidative phosphorylation and the formation of ATP also called energy coins for the cell. Mammalian mitochondrial genome (mtDNA) is a double stranded, circular, covalently closed molecule of approximately size of 16.4 kb. The mtDNA is inherited from the mother as a haploid and heteroplasmy has been found hardly.This fact makes it potentially relevant in the identification of maternal relationships, absence of recombination and the fast rate of evolution Blood/tissue samples were collected from Class Mammals (one specimen from every order reported to be present in Pakistan). DNA was extracted from the collected specimens through standard organic method, qualified and quantified and then PCR-amplified using novel universal primers selected from aligned mtDNA sequences originating from all mammalian mitochondrial DNA genomes submitted to different online sequence databases such as NCBI nucleotide database. The sensitivity of PCR also be assessed using a range of DNA concentrations. The amplified products were sequenced on ABI Genetic Analyzed following Sanger’s dideoxy method of Summary 67 sequencing. The correctness of obtained mtDNA sequences were examined visually in Chromas Lite 2.1 software and then alignment of these sequences were performed against highly similar DNA sequences in NCBI nucleotide databases using BLAST in order to identify the origin of unknown mtDNA sequences. Both sequencing experiments and phylogenetic studies confirmed the specificity of the universal primer set developed and present a novel metabarcode found in this region of genome (16SrRNA) for species level identification of large number of mammalian species. So, in future, this barcode can be used for species identification in various fields of study such as meat adulteration, illegal trade, food mislabeling and molecular estimation of biodiversity.
