Identification And Characterization Of Cysteine Protease Genes In Tobacco For Use In Recombinant Protein Production, Kishor Duwadi
Identification And Characterization Of Cysteine Protease Genes In Tobacco For Use In Recombinant Protein Production, Kishor Duwadi
Electronic Thesis and Dissertation Repository
Plants are an attractive host system for pharmaceutical protein production. Many therapeutic proteins have been produced and scaled up in plants at a low cost compared to the conventional microbial and animal based systems. The main technical challenge during this process is to produce sufficient level of proteins in plants. Low yield is generally caused by proteolytic degradation during expression and downstream processing of recombinant proteins. The yield of a human therapeutic protein interleukin (IL) -10 produced in transgenic tobacco leaves was found to be below the critical level, and is potentially due to degradation by tobacco cysteine proteases (CysPs). …
Transcriptional Regulation Of Peptidylarginine Deiminase Type Iv: Implications For Rheumatoid Arthritis, Ali Abbas
Electronic Thesis and Dissertation Repository
High titers of anti-citrullinated protein antibodies have been detected in sera of rheumatoid arthritis (RA) patients, implicating citrullinating enzymes in the pathogenesis of RA. Peptidylarginine deiminase type IV (PAD4) is a member of the PAD family of enzymes that catalyze the post- translational modification of arginine to citrulline and has been linked with RA. However, little is known about its transcriptional regulation. Therefore, our aim was to determine how transcription of PAD4 is activated in the myeloid lineage. Using bioinformatics, a potential nuclear factor kappa B (NF-kB) binding site was identified on the PAD4 promoter. Luciferase assays were used to …
