Identifying The Cell Composition And Clonal Diversity Of Supratentorial Ependymoma Using Single Cell Rna-Sequencing, James He
Honors Scholar Theses
Ependymoma is a primary solid tumor of the central nervous system. Supratentorial ependymoma (ST-EPN), a subtype of ependymomas, is driven by an oncogenic fusion between the ZFTA and RELA genes in 70% of cases. We introduced this fusion into neural progenitor cells of mice embryos via in utero electroporation of a non-viral binary piggyBac transposon system containing ZFTA-RELA. From preliminary data in the LoTurco lab, inducing the expression of ZFTA-RELA into different neural progenitor cells produces tumors of varying lethality and cellular composition. To define the cellular composition and subclonal diversity of ST-EPN tumors, we used single cell RNA-sequencing …
Identifying New Genes Involved In Centromere Establishment, Megan Boyer
Identifying New Genes Involved In Centromere Establishment, Megan Boyer
Honors Scholar Theses
The centromere is a site on the chromosome that mediates accurate cell division by serving as a platform for kinetochore assembly, and microtubule attachment during cell division. Errors in the process of chromosome segregation can contribute to genetic irregularities, such as those seen in cancer and congenital defects. Our lab uses the ectopic centromere as a tool to discover what proteins may be involved in centromere establishment, defined as the deposition of CENP-A at the locus. We use the lacO/LacI system within Drosophila S2 cells that contain a CAL1-GFP- LacI transgene and an integrated lacO array to study the ectopic …
In Vitro Characterization Of Avian Influenza Virus Isolates With A Truncated Ns1 Gene Segment, Aaron Dick
In Vitro Characterization Of Avian Influenza Virus Isolates With A Truncated Ns1 Gene Segment, Aaron Dick
Honors Scholar Theses
Avian Influenza Virus represents a significant threat to the world poultry population, and is a potential threat to humans due to the possibility of cross-species AIV infection. Our approach is to characterize a number of avian virus populations with respect to their content of biologically active particles that include hemagglutinating particles (HAP), plaque forming particles (PFP), interferon inducing particles (IFP), interferon induction-suppressing particles (ISP), defective-interfering particles (DIP), cell-killing particles (CKP) and non-infectious cell killing particles (niCKP) using unique in vitro assays developed for avian influenza virus in the Marcus-Sekellick Laboratory. Specifically, we will use a strain of Avian influenza virus, …
