Investigating Bmp7 Expression In Glioblastoma Multiforme, Yajaira Janett Macias
Theses and Dissertations
The PI3K/AKT/mTOR pathway regulates important cell processes such as growth, survival, motility, inflammation, proliferation, and apoptosis. In Glioblastoma multiforme (GBM) the PI3K/AKT/mTOR pathway is aberrant as it is almost always active. This results in the deregulation of downstream molecules and ultimately leads to cancer progression and maintenance in GBM tumors. In this study, we used RNA-sequencing to identify differentially expressed genes (DEGs) in U87MG GBM cells treated with NVP-BEZ235, a dual inhibitory drug targeting PI3K and mTOR. A total of 7,803 differentially expressed genes were identified via RNA-seq. GEPIA2 online tool was used to assess differential gene expression …
Novel Insights Into The Contribution Of Cellular Senescence To Cancer Therapy: Reversibility, Dormancy And Senolysis., Tareq Saleh
Novel Insights Into The Contribution Of Cellular Senescence To Cancer Therapy: Reversibility, Dormancy And Senolysis., Tareq Saleh
Theses and Dissertations
Cellular senescence a specialized form of growth arrest that contributes to the pathogenesis of several aging-related disorders including cancer. While by definition tumor cells are considered immortalized, they can undergo senescence when exposed to conventional and targeted cancer therapy. Therapy-Induced Senescence (TIS) represents a fundamental response to therapy and impacts its outcomes. However, TIS has been considered a positive therapeutic goal since senescent tumor cells are expected to enter a state of permanent growth abrogation. In this work we examined the hypothesis that a subpopulation of senescent cells can re-acquire proliferative potential after a state of senescent dormancy, indicating that …
Evaluation And Adaptation Of Live-Cell Interferometry For Applications In Basic, Translational, And Clinical Research, Kevin A. Leslie
Evaluation And Adaptation Of Live-Cell Interferometry For Applications In Basic, Translational, And Clinical Research, Kevin A. Leslie
Theses and Dissertations
Cell mass is an important indicator of cell health and status. A diverse set of techniques have been developed to precisely measure the masses of single cells, with varying degrees of technical complexity and throughput. Here, the development of a non-invasive, label-free optical technique, termed Live-Cell Interferometry (LCI), is described. Several applications are presented, including an evaluation of LCI’s utility for assessing drug response heterogeneity in patient-derived melanoma lines and the measurement of CD3+ T cell kinetics during hematopoietic stem cell transplantation. The characterization of mast cells during degranulation, the measurement of viral reactivation kinetics in Kaposi’s Sarcoma, and drug …
