Abstract

Cell-based diabetes therapy may be achieved through xenotransplantation of adult porcine islets, but tissue quality and immunoreactivity barriers need to be overcome. Early identification and exclusion of irreversibly stressed and dying islets may improve transplant outcomes. We used oligonucleotide microarray and quantitative RT-PCR to identify molecular markers of physiological and immunological stress in porcine islets cultured under stress conditions of elevated glucose (16.7 mM), inflammatory cytokine addition (IL-1β, TNF-α, and IFN-γ), or both, for 48 h. Hyperglycemic conditions were associated with increased thioredoxin interacting protein and metabolic process mRNAs, as observed in rodent and primate species. Cytokine treatment increased expression of JAK-STAT pathway components, oxidative stress (transglutaminase 2), and β cell dysfunction genes. Transglutaminase 2 induction is unique to porcine islets. Biomarkers involved in hyperglycemia and islet inflammation may serve as novel targets for improving and monitoring isolated porcine islet function and viability.
