Detection Of Insulin Receptor, Epidermal Growth Factor Receptor, And Interleukin-6 On Individual Mouse Embryos By Immuno-Polymerase Chain Reaction, Kun Xu
Electronic Theses and Dissertations
Three series of experiments were conducted to: 1) optimize the conditions for the production of pUC19 plasmid and of biotinylated pUC19 fragments; 2) optimize the conditions for the production of protein A-streptavidin chimera (chimeric protein); and 3) detect soluble antigens [bovine serum albumin (BSA) and interleukin-6 (IL-6)] and membrane-bound antigens [insulin receptor and epidermal growth factor receptor (EGFr)] of mouse embryos by immuno-polymerase chain reaction (I-PCR). The first experimental series, which included bacterial culture, chimeric protein purification, and chimeric protein functional experiments, was performed to investigate the effects of IPTG (isopropyl-β-D-thiogalactopyranoside) induction time and temperature, bacterial culture medium, and protein …
Cold-Temperature Adaptation Of Muscle Creatine Kinase From An Antartic Teleost (Chaenocephalus Aceratus), Paul Winnard Jr.
Cold-Temperature Adaptation Of Muscle Creatine Kinase From An Antartic Teleost (Chaenocephalus Aceratus), Paul Winnard Jr.
Electronic Theses and Dissertations
The white muscle of Chuenocephulus aceratus, an Antarctic teleost of the Channicthyidae family, has a compromised glycoiytic capacity and this fish cannot depend on glycolysis for rapid ATP generation For C. aceratus, creatine kinase (CK) and phosphocreatine (PCr) reserves comprise the metabolic pathway that may supplement and overcome this deficiency in energy transduction. Two conditions, low glycolytic capacity and evolution in a chronically cold habitat (-1.86°C), give us reason to believe that C. aceratus muscle CK (MMCK) has been subjected to strong selective pressure. Thus, the hypothesis of this thesis is that MMCK fiom C. aceratus white muscle …
Quinic Acid-Mediated Induction Of Hypovirulence And A Hypovirulence-Associated Double-Stranded Rna In Rhizoctonia Solani, Chunyu Liu
Electronic Theses and Dissertations
This study is a part of a project focused on the relationship between dsRNA and hypovirulence in R. solani. Hypovirulence refers to a condition in which a pathogen has a drastically reduced ability to cause disease. Rhizoctonia solani is a soil-borne pathogen causing diseases in numerous plants. Phenyl acetic acid (PAA), a metabolite of phenylalanine, causes Rhizoctonia disease symptoms on potato in the absence of the pathogen itself. The amount of PAA produced by a hypovirulent isolate is 10% of that produced by virulent isolates. A 3.6 kb dsRNA (M2) has been shown to be associated with hypovirulence in …

Baculovirus-expressed recombinant Sir3p (rSir3p) has been purified to near homogeneity, and its binding to naked DNA, mononucleosomes, and nucleosomal arrays has been characterized in vitro. At stoichiometric levels rSir3p interacts with intact nucleosomal arrays, mononucleosomes, and naked DNA, as evidenced by formation of supershifted species on native agarose gels. Proteolytic removal of the core histone tail domains inhibits but does not completely abolish rSir3p binding to nucleosomal arrays. The linker DNA in the supershifted complexes remains freely accessible to restriction endonuclease digestion, suggesting that both the tail domains and nucleosomal DNA contribute to rSir3p–chromatin interactions. Together these data indicate …
Positive Regulation Of Pka On Human Gonadotropin-Releasing Hormone (Hgnrh) Gene Expression In Human Placental Jeg-3 Cells, Zhaoyang Wen
Positive Regulation Of Pka On Human Gonadotropin-Releasing Hormone (Hgnrh) Gene Expression In Human Placental Jeg-3 Cells, Zhaoyang Wen
Chemistry & Biochemistry Theses & Dissertations
Using the human placental choriocarcinoma JEG-3 cell line as an in vitro human placental model, we studied the mechanisms of the PKA positive regulation of the hGnRH gene expression in the human placenta. Studies in JEG3 cells showed that through the PKA catalytic subunit a, human GnRH upstream promoter activity was stimulated by PKA signaling pathway in a cAMP dependent mechanism. The sequence between —202 (Afl II) and —554 (BamH I) base pair in the human GnRH upstream promoter region appeared to be responsible for the PKA positive regulation of the gene expression. Furthermore, Western blot analysis demonstrated the involvement …
