Research Interests

Approximately one-third of alleles causing genetic diseases carry premature termination codons (PTCs), which lead to the production of truncated proteins. Our laboratory seeks better therapeutic approaches aimed at readthrough of in-frame PTCs to enable synthesis of full-length proteins, including genetic incorporation of unnatural amino acids, suppressor tRNAs, stem cell therapy, single base editing systems to treat PTC-mediated diseases. We study the mechanistic underpinnings of PTC suppression, including the efficiency of termination differs between normal stop codons and premature termination codons. Meanwhile we established 17 types of PTC stable cell lines containing unnatural amino acids incorporation systems, suppressor tRNAs, or Heavy/light chain antibodiesto develop virus vaccines and therapeutic antibodies for biodefense.
