The Effect Of Ultraviolet Light On Cell Viability, Dna Damage And Repair In Hutchinson-Gilford Progeria Syndrome And Bj Fibroblasts., Mckayla Johnson
The Effect Of Ultraviolet Light On Cell Viability, Dna Damage And Repair In Hutchinson-Gilford Progeria Syndrome And Bj Fibroblasts., Mckayla Johnson
Undergraduate Honors Theses
Patients of Hutchinson-Gilford Progeria Syndrome (HGPS) display a rate of aging up to ten times that of normal human populations. It might be expected that HGPS cells would have a decreased ability to repair DNA damage through the cell cycle as compared to normal cells such as those of the BJ cell line since DNA damage accumulation is a hallmark phenotype of aging. On earth, we are exposed to far more ultraviolet-B (UV-B, 280-315 nm) and UV-A (315-400 nm) than UV-C (100-280 nm) radiation, since the latter is filtered-out by the atmospheric ozone layer. The relative sensitivity of prematurely aging …

The Effects Of The Vitamin E Isomers Gamma Tocopherol And Gamma Tocotrienol On The Nfkb Pathway In The Pc-3 Cell Line., Brittney Rudder

Regions along the Mediterranean and Southern Asia have lower prostate cancer incidence compared to the rest of the world. It has been hypothesized that one of the potential contributing factors for this low incidence includes a higher intake of vitamin E (tocopherols and tocotrienols). This study examines the potential of gamma tocopherol (GT) and gamma tocotrienol (GT3) to reduce prostate cancer proliferation by examining their effects on the NFκB pathway. NFκB is known to inhibit apoptosis in cancer cells. Our data shows that both GT and GT3 are capable of down regulation of NFκB precursors and up regulation of Caspase …
Effects Of Vitamin E Isomer, Gamma Tocotrienol (Gt3), At Inhibiting Cell Growth And Inducing Apoptosis In Colon Cancer Cell Line Hct-116., Havya Dave
Undergraduate Honors Theses
Colorectal cancer is the third most prominent cancer world-wide and it is the second leading cause of cancer deaths in the United States. Many dietary components affect the risk of developing colorectal cancer, such as Vitamin E. Of the eight isomers of Vitamin E, four have a tocotrienol structure. Tocotrienols are found at highest concentrations in palm oil, which is ingested more in areas of Asia where the incidence of colorectal cancer is the lowest, suggesting a role of tocotrienols in the prevention of colorectal cancer. The metabolism of Arachidonic acid pathway produces a host of pro-inflammatory metabolites either by …
Molecular Modulation Of A-Subunit Visit-Dg Sequence Residue Asp-350 In The Catalytic Sites Of Escherichia Coli Atp Synthase., Sneha R. Jonnalagadda
Molecular Modulation Of A-Subunit Visit-Dg Sequence Residue Asp-350 In The Catalytic Sites Of Escherichia Coli Atp Synthase., Sneha R. Jonnalagadda
Electronic Theses and Dissertations
ATP Synthase is the fundamental means of cellular energy production in animals, plants, and almost all microorganisms. In order to understand the mechanism of ATP catalysis, critical amino acid residues involved in Pi binding have to be identified. The αVISIT-DG sequence at the interface of α/β subunits that contains residues from 345-351 is highly conserved and αAsp-350 has been chosen because of its negative charge side chain and its close proximity (~2.8 Å) to the known phosphate binding residue αArg-376. The mutant's αD350R, αD350Q, αD350A, αR376A/D, and αG351R/A/D were generated by site directed mutagenesis and several biochemical assays were performed …
