  • Environmental complex mixtures modify benzo[a]pyrene and dibenzo[a,l]pyrene-induced carcinogenesis

    Creator:
    Courter, Lauren A.
    Abstract:
    Human exposure to the carcinogenic polycyclic aromatic hydrocarbons (PAHs) benzo[a]pyrene (B[a]P) and dibenzo[a,l]pyrene (DB[a,l]P) is through environmental complex mixtures, such as urban dust particulate matter (UDPM) and diesel exhaust (DE), however the potency of these PAH within a mixture is not established. To determine the effect of these mixtures on...

  • Age-related alterations in transcriptional regulation of hepatic glutathione synthesis : remediation by R-alpha-lipoic acid

    Creator:
    Shenvi, Swapna V.
    Abstract:
    Glutathione (GSH) is the predominant low molecular weight thiol antioxidant in liver tissue. GSH plays an important role in maintaining the intracellular thiol redox ratio as well as detoxification of electrophiles and xenobiotics. Aging leads to a significant decline (35%; P ≤ 0.05) in hepatocellular GSH levels. Using young (2-4...

  • In vivo assessment of nanomaterial-induced toxicity using embryonic zebrafish

    Creator:
    Usenko, Crystal Y.
    Abstract:
    Due to their unique physical, chemical, and magnetic properties, nanomaterials have great potential for industrial development. There is a pressing need to develop rapid whole animal-based testing assays to assess the potential toxicity of engineered nanomaterials. To meet this challenge the embryonic zebrafish model was employed to determine the toxicity...

  • Unraveling tissue regeneration using chemical genetics

    Creator:
    Mathew, Lijoy K.
    Abstract:
    The emerging field of regenerative medicine is mainly approached by two different aspects. First is the use of stem cell based models to generate a suite of differentiated cells for therapeutic applications and the alternative approach is to utilize the non-mammalian models that have the inherent capacity to regenerate their...

  • Factors contributing to the formation of CC-->TT tandem mutations

    Creator:
    Skinner, Amy M.
    Abstract:
    The multistage model of carcinogenesis states that an accumulation of mutations in genes that are important for maintaining cellular homeostasis may lead to cancer. A specific type of mutation observed in particular types of cancer is the CC-->TT mutation found in the TP53 gene of patients with basal or squamous...

  • Electron molecule interactions of amino acids and peptides

    Creator:
    Figard, Benjamin J.
    Abstract:
    Electron-biomolecule interactions are a biologically relevant field of study because there are several ion fragmentation techniques that have come to the forefront in mass spectrometric analysis that involve the interaction of charged peptides and free electrons. By studying the electron energies that cause fragmentation in neutral amino acids, amino acid...
