Metabolic Rescue Of “Glucose Addicted” Cancer Cells In Vitro, Paolo Vignali
Metabolic Rescue Of “Glucose Addicted” Cancer Cells In Vitro, Paolo Vignali
Pursuit - The Journal of Undergraduate Research at The University of Tennessee
Transformations in the glycolytic metabolism of neoplasms modulate their robust cellular division. This characteristic leads to an “addiction” to glucose for continued proliferation and viability. This study investigated whether glucose metabolites could rescue cellular viability in glucose-starvation conditions, a model of the inter-tumoral nutrient-deficient environment. Findings illustrated potential cellular viability rescue with pyruvate addition in glucose-deprived conditions, yet the same potential was not observed with lactic acid, a metabolite that exists at characteristically high concentrations within the intertumoral microenvironment. These results could implicate a predominance of certain metabolic pathways in nutrient-starved cells. Molecular transport capacities across plasma membranes are tied …

Histone modifying enzymes and chromatin remodeling complexes play an important regulatory role in chromatin dynamics that dictate the interaction of regulatory factors involved in processes such as DNA replication, recombination, repair and transcription, with DNA template. The CHD (Chromodomain Helicase DNA Binding Protein) family of proteins is known to be involved in the regulation of gene expression, recombination and chromatin remodeling via their chromatin specific interactions and activities. Phenotypic analysis of the Chd2 mutant mouse model developed by our laboratory indicates that the Chd2 protein plays a critical role in tumor suppression as the heterozygous mutant mice develop spontaneous lymphomas. …
