Homothorax Is A Modifier Of Radiation Sensitivity In Drosophila Melanogaster Bantam Mutants, Geoffrey Meyerhof Jan 2017

Homothorax Is A Modifier Of Radiation Sensitivity In Drosophila Melanogaster Bantam Mutants, Geoffrey Meyerhof

Undergraduate Honors Theses

Radiation resistance in human cancers represents a massive impediment for successful tumor treatment. The fruit fly Drosophila melanogaster is an excellent model for human radiation resistance because of its largely conserved apoptotic pathways and malleable genome. This thesis investigates the genetic regulatory mechanisms for bantam (ban), an anti-apoptotic microRNA. To first identify genes that interact with ban, a forward genetic screen was conducted. This screen looked for genes that yielded radiation dependent pupal lethality in a ban deficient background. From this screen the transcription factor, homothorax, was identified as displaying radiation dependent synthetic lethality with ban. To investigate the mechanism ...
