Splice Factor Sfrs6: Regulation By P53 And Effect On Il-24 Splicing, Erin L. Schmidt
Splice Factor Sfrs6: Regulation By P53 And Effect On Il-24 Splicing, Erin L. Schmidt
Loma Linda University Electronic Theses, Dissertations & Projects
Alternative splicing of RNA transcripts is emerging as a major mechanism for expanding the proteome. Splice pattern changes are found in numerous diseases and cancers, indicating the importance of tight control over this process. While the mechanism of splicing has been described in detail, it is less clear how a cell is able to modify its splicing patterns in response to different conditions. Our lab previously demonstrated that DNA damage can induce SFRS6, the gene coding for splicing factor SRp55, thereby leading to changes in the splicing patterns of several target genes related to survival and apoptosis. We also …
Fetal Programming By Nicotine Increases Cardiac Susceptibility To Ischemic Injury, Jennifer Charlotte Alexie Lawrence
Fetal Programming By Nicotine Increases Cardiac Susceptibility To Ischemic Injury, Jennifer Charlotte Alexie Lawrence
Loma Linda University Electronic Theses, Dissertations & Projects
Fetal programming is the area of study that focuses on the prenatal origins of adult onset disorders. Previous studies have associated an adverse prenatal environment with the onset of physiologic and metabolic diseases during adulthood. Fetal malnutrition, hypoxia, and exposure to drugs - such as cocaine and nicotine - have been associated with adult disease states. Cigarette smoking is the number one cause of preventable death in the developed world. Among the many dangerous chemicals found in tobacco products is nicotine, the compound responsible for the addictive nature of tobacco use. Nicotine use during pregnancy is a known cause of …

Regulation Of Pim1 Under Hypoxia In Prostate Cancer, Eva Sahakian
Loma Linda University Electronic Theses, Dissertations & Projects
A defining characteristic of solid tumors is the capacity to divide and spread under conditions of nutrient deprivation and limited oxygen availability. These microenvironmental stresses arise from structural abnormalities in tumor vessels that lead to aberrant microcirculation. Hypoxia acts as a physiological “selection pressure” in the progression of cancer by activating pathways and enhancing the expression of specific genes in tumor cells which eventually diminish their apoptotic potential. Ultimately, hypoxic microenvironment functions as a “stress factor”, selecting cells with the ability to survive and divide under anoxic conditions. The members of the PIM family of cytoplasmic serine threonine kinases are …
Structural Dynamics And Signaling Roles Of The Aer Pas And F1 Regions, Asharie J. Campbell
Structural Dynamics And Signaling Roles Of The Aer Pas And F1 Regions, Asharie J. Campbell
Loma Linda University Electronic Theses, Dissertations & Projects
The Aer aerotaxis receptor in Escherichia coli mounts such a rapid response to redox that E. coli changes its swimming behavior within 100 ms after an oxygen pulse. This receptor is a membrane-bound homodimer, and it monitors internal energy (redox) via an FAD cofactor bound to a cytoplasmic N-terminal PAS domain. Understanding PAS sensing is important, as PAS domains comprise a superfamily of more than 25,000 members from all kingdoms. This study focused on the Aer N-terminal PAS sensor, as well as the region tethering it to the membrane anchor, known as the F1. Previous genetic studies on these regions …
