Complimenting a Chlamydomonas reinhardtii Mutation Using Cell Penetrating Peptides

Matthew McKenzie and Jennifer L. Cooper

Chlamydomonas reinhardtii is a photosynthetic model organism most notable for its easily manipulatable genetics. C. reinhardtii uses flagella to swim and optimize its growth conditions in the light. We plan to use cell penetrating peptides (CPPs) to compliment C. reinhardtii that is affected with the IFT46 mutation. Cell penetrating peptides are short peptides that can move across a cell membrane. The novel CPP that we are using is called TaT-CaM. It consists of the trans-activator of transcription (TaT) and the calmodulin domain (CaM) that binds …

The Role Of Proneural Transcription Factor Ngn-1/Neurogenin During Caenorhabditis Elegans Embryonic Development, Michaela Diane Crego

Symposium of Student Scholars

Accurate control of neuronal cell identification and movement is crucial to embryonic development. Defects in this process can lead to neurodevelopmental disorders, creating an imperative for further study. The transcription factor neurogenin is required for multiple neurodevelopmental processes during vertebrate embryonic development and mutations in this gene underpin multiple human neurological disorders. Despite this, little is known about how this gene controls nervous system development and function. Neurogenin is deeply conserved across phyla. As such, we can investigate neurogenin function in simple systems such as the nematode Caenorhabditis elegans, which has a close ortholog of neurogenin, ngn-1. Previous work in …
