Feasibility Of Tubulin As A Control For Gene Expression Following Transfection In Mouse Monocyte/Macrophage-Like Cells, Ankita Chabra
Feasibility Of Tubulin As A Control For Gene Expression Following Transfection In Mouse Monocyte/Macrophage-Like Cells, Ankita Chabra
Honors Program Theses and Research Projects
Transfection, which is the ability to modify host cells’ genetic content, has broad application in studying normal cellular processes, molecular mechanism of disease and gene therapy. There are several transfection techniques, and all require either a control or a reference gene. Commonly used controls for transfection experiments are housekeeping genes, which maintain expression for a given cell/tissue, experimental conditions, and treatment. However, recent research has uncovered that expression levels of housekeeping genes may vary depending on the gene, cell type and experimental conditions. A growing body of evidence demonstrates that housekeeping genes are inadequate internal standards for measuring gene expression …

A combined MD simulator and time dependent Laplace solver are used to analyze the electrically driven phosphatidylserine externalization process in cells. Time dependent details of nanopore formation at cell membranes in response to a high-intensity (100kV∕cm), ultrashort (10ns) electric pulse are also probed. Our results show that nanosized pores could typically be formed within about 5ns. These predictions are in very good agreement with recent experimental data. It is also demonstrated that defect formation and PS externalization in membranes should begin on the anode side. Finally, the simulations confirm that PS externalization is a nanopore facilitated event, rather than the …

Electroporation Dynamics In Biological Cells Subjected To Ultrafast Electrical Pulses: A Numerical Simulation Study, R. P. Joshi, K. H. Schoenbach
Bioelectrics Publications
A model analysis of electroporation dynamics in biological cells has been carried out based on the Smoluchowski equation. Results of the cellular response to short, electric pulses are presented, taking account of the growth and resealing dynamics of transient aqueous pores. It is shown that the application of large voltages alone may not be sufficient to cause irreversible breakdown, if the time duration is too short. Failure to cause irreversible damage at small pulse widths could be attributed to the time inadequacy for pores to grow and expand beyond a critical threshold radius. In agreement with earlier studies, it is …
