The goal of this project was to design and create a genetic construct that would allow for <br/>tumor growth to be induced in the center of the wing imaginal disc of Drosophila larvae, the <br/>R85E08 domain, using a heat shock. The resulting transgene would be combined with other <br/>transgenes in a single fly that would allow for simultaneous expression of the oncogene and, in <br/>the surrounding cells, other genes of interest. This system would help establish Drosophila as a <br/>more versatile and reliable model organism for cancer research. Furthermore, pilot studies were <br/>performed, using elements of the final proposed system, to determine if tumor growth is possible <br/>in the center of the disc, which oncogene produces the best results, and if oncogene expression <br/>induced later in development causes tumor growth. Three different candidate genes were <br/>investigated: RasV12, PvrACT, and Avli.
The transcriptome of an organism is a collection of the various messenger RNAs that the genes of an organism produce. As the level of gene expression is different between different tissues of an organism, understanding the transcriptome serves as a way to better understand the differences between the functions and abilities of tissues and cells in an organism. This understanding of the transcriptome can aid further research in targeted disease treatments and indentifying new biomarkers. This study aims to gather the transcriptome from various tissues of the organism Daphnia pulex. This will be done by using a combination of single cell RNA sequencing (scRNA-seq), which involves the isolation and sequencing of single cells, and single nuclei RNA sequencing (snRNA-seq), which involves the isolation and sequencing of single nuclei. Here we show the viability of isolating single cells and single nuclei from various Daphnia pulex tissues using different techniques and enzymes including trypLE, trypsin EDTA, accutase, etc by using microscopy and automatic cell counting. The results show that each tissue is best isolated using different techniques.
This thesis summarizes the process of writing a children's book about achondroplasia directed at children without genetic disorders. The thesis also includes the children's book The Genetics of Little People that was created during the project.
