The Role Of Gene Expression Noise In Mammalian Cell Survival, Kevin Farquhar
The Role Of Gene Expression Noise In Mammalian Cell Survival, Kevin Farquhar
Dissertations & Theses (Open Access)
Drug resistance and metastasis remain obstacles to effective cancer treatment. A major challenge contributing to this problem is cellular heterogeneity. Even in the same environment, cells with identical genomes can display cell-to-cell differences in gene expression, also known as gene expression noise. Gene expression noise can vary in magnitude in a population or in fluctuation time scales, which is influenced by gene regulatory networks.
Currently, it is unclear how gene expression noise from gene regulatory networks contributes to drug survival outcomes in mammalian cells. An isogenic cell line with a noise-modulating genetic system tuned to the same mean is required. …
Investigating The Role Of Prmt1 And Arginine Methylation Of Hsp70 In Human Pancreatic Cancer, Liang Wang
Investigating The Role Of Prmt1 And Arginine Methylation Of Hsp70 In Human Pancreatic Cancer, Liang Wang
Dissertations & Theses (Open Access)
Protein arginine methyltransferase 1 (PRMT1) is the major arginine methyltransferase, which catalyzes the addition of one or two methyl groups to the arginine residues of its substrate proteins. The best-known substrate for PRMT1 is histone, while more and more non-histone proteins are now found to be methylated by PRMT1. Dysregulation of PRMT1 is reported in several human cancer types. However, its biological roles in human pancreatic cancer initiation and development are still unclear. In the first part of this study, I found that the expression level of PRMT1 was elevated in both human and mouse pancreatic cancer tissues in immunohistochemistry …
