Barrett, The Honors College at Arizona State University proudly showcases the work of undergraduate honors students by sharing this collection exclusively with the ASU community.

Barrett accepts high performing, academically engaged undergraduate students and works with them in collaboration with all of the other academic units at Arizona State University. All Barrett students complete a thesis or creative project which is an opportunity to explore an intellectual interest and produce an original piece of scholarly research. The thesis or creative project is supervised and defended in front of a faculty committee. Students are able to engage with professors who are nationally recognized in their fields and committed to working with honors students. Completing a Barrett thesis or creative project is an opportunity for undergraduate honors students to contribute to the ASU academic community in a meaningful way.

Description

Okur-Chung Neurodevelopmental syndrome (OCNDS) is a rare disorder characterized by hypotonia, developmental delay, dysmorphic features, and more. It is caused by pathogenic variants on CSNK2A1, the α subunit of protein kinase CK2. CK2 is considered a master regulator involved in many cell functions from cell differentiation and proliferation to apoptosis.

Okur-Chung Neurodevelopmental syndrome (OCNDS) is a rare disorder characterized by hypotonia, developmental delay, dysmorphic features, and more. It is caused by pathogenic variants on CSNK2A1, the α subunit of protein kinase CK2. CK2 is considered a master regulator involved in many cell functions from cell differentiation and proliferation to apoptosis. Here, we create a potential zebrafish model of OCNDS with CK2 inhibition and characterize fibroblast cells with, K198R, D156E, and R47G variants of CSNK2A1. RNAseq results display a wide range of effects notably in the Myosin Protein superfamily, Insulin-like Growth Factor family, and in proteins related to mitochondrial function and cell metabolism. Factors in cell growth and metabolism across the nervous system and neuromuscular interactions appear to be most affected with similarities in markers to oncogenic states in some cases.
