Among gynecological malignancies, carcinoma of the cervix is the leading cancer type worldwide. Conversely, vaginal tumors account for an incidence of approximately 1-2% of lower genital tract malignancies. Interestingly, the major shared risk...
Long-term exposure to harmful carcinogens like benzo[a]pyrene (BaP) are linked to lung cancer. Benzo[a]pyrene diol epoxide (BPDE), the ultimate carcinogen produced by BaP bioactivation, is believed to play an important role in lung carcinogenesis....
Unrepaired DNA damage poses a serious threat to the genetic stability of a replicating cell. One mechanism of tolerating this damage is translesion DNA synthesis (TLS), in which an accessory polymerase synthesizes DNA directly across from a damaged...
Few previous studies have compared microbial communities in subterranean and surface environments. Chemical analyses used to characterize the surface and cave microbial environments indicated limited exchange between surface and subsurface waters....
Periodontitis is a chronic, destructive inflammatory disease of the supporting
tissues of the teeth with a high prevalence among adults. While the complete
pathogenesis of periodontitis remains unclear, it is initiated and sustained by...
Ribosomal biogenesis failure may contribute to neurodegenerative diseases, while its excessive activation has been shown to drive tumor growth. As ribosomal production is initiated and regulated by the Pol1-mediated transcription of rRNA genes in...
Epithelial Ovarian cancer (EOC) is the leading cause of gynecological cancer death in the USA. Recurrence rates are high after front-line platinum chemotherapy and most patients eventually die from platinum-resistant disease. P53 plays an important...
Recent advances in understanding the molecular mechanisms of mutagenesis indicate that most mutations are dependent on the activity of translesion synthesis DNA polymerases. The impact of reducing the level of these polymerases on mutagenesis and...
The Y family of DNA polymerases in higher eukaryotes contains at least four members which are implicated in potentially error-prone replication through unrepaired damage in the genome. These proteins are encoded by the REV1, POLH, POLI, and POLK...
Green tea--Health aspects; Green tea--Therapeutic use; Polyphenols--Physiological effect; Drug delivery systems; Lungs--Cancer--Treatment
Green tea polyphenols (GTPs) are gaining increasing attention because of their potential anti-tumor effects. However, poor oral bioavailability limits their efficacy in vivo. In this dissertation, two hypotheses were tested: 1) GTPs administered...
In the age of high-throughput molecular biology techniques, scientists have incorporated the methodology of in-situ hybridization to map spatial patterns of gene expression. In order to compare expression patterns within a common tissue structure,...
Current high-throughput gene expression experiments have a straightforward design of examining
the gene expression of one group or condition relative to that of another. The data is typically
analyzed as if they represent strictly intracellular...
While investigating estrogen response element (ERE) binding properties of Erα in de-identified human breast cancer extracts, additional proteins were observed that recognized ERE sequences (ERE-BP). In order to unravel the apparent role of these...
Background: When rat salivary gland cells are cultured in vitro, they dedifferentiate within 24 h. Hypothesis: Growth factors will prevent de-differentiation of primary cultures of parotid gland cells, and they will induce differentiation of ParC5...
High-throughput sequencing has provided a myriad of genetic data for thousands of organisms. Computational analysis of one data type, expressed sequence tags (ESTs) yields insight into gene expression, alternative splicing, tissue specificity gene...
Colon (Anatomy)--Cancer--Genetic aspects; Cancer cells--Mathematical models
Research over the past twenty five years has led to the development of the hypothesis that colorectal cancer is caused by the accumulation of mutations in tumor suppressor genes and proto-oncogenes. The last ten years has also revealed that the...
Arylamine N-acetyltransferase 1 (NAT1) and 2 (NAT2) catalyze the detoxification and/or activation of aromatic and heterocyclic amine carcinogens by two pathways. This metabolism reaction can lead to the detoxification by Nacetylation, or...
Recent studies indicate post-translational deacetylation by members of the superfamily of histone deacetylase complexes (HDACs) is necessary for oligodendrocyte precursor cell (OPC) differentiation into mature oligodendrocytes (OLs). However, it...
Pancreatic beta cells are extremely vulnerable to the destruction of Reactive Oxygen Species (ROS). In both type 1 and type 2 diabetes ROS are involved in the loss of U+000DF-cells. We hypothesized that the deficiency in ROS detoxifying system of...
Genes in folate metabolizing pathway are responsible for modulating key enzymes in folate metabolisms necessary for DNA synthesis and repair and influence DNA methylation. Irregularity in DNA methylation may modify tumor phenotype response to...
