Emphasizing equitable and inclusive access to research opportunities, the University of Maryland's Office of Undergraduate Research (OUR) empowers undergraduates and faculty to engage and succeed in inquiry, creative activity, and scholarship. This collection includes materials shared by undergraduate researchers during OUR events. It also encompasses materials from Undergraduate Research Day 2020, Undergraduate Research Day 2021, and Undergraduate Research Day 2022, which were organized by the Maryland Center for Undergraduate Research.

    Ribosome biogenesis is vital for a cell to make proteins and proceed through the central dogma of molecular biology. Human ribosomal proteins (RPs) RPS17 and RPS23 are protein-encoding genes associated with the formation of ribosomes in cells. Serious diseases are linked to dysfunction of RPS17 and RPS23. Mutations in RPS17 have been linked to Diamond-Blackfan anemia, a rare inherited bone marrow disease that affects red blood cells, leading to anemia. RPS23 protein dysfunction is linked to Hepatocellular carcinoma, a severe form of liver cancer. In this study, RPS17 and RPS23 were cloned and expressed with two different bacterial expression plasmids, pNIC28-Bsa4 and pNH-TrxT, with 100% sequence confirmation. Plasmids were then transformed into BL21 E. coli cells, and IPTG induction was used to express RPS17 and RPS23. SDS-PAGE, followed by Coomassie staining, was conducted to confirm the successful expression of the proteins. Future research will determine how overexpression and posttranslational modifications of RPS17 and RPS23 link to cellular growth and homeostasis.
