Abstract | BACKGROUND: METHODS: RESULTS: In a transgenic pancreatitis model, TAP and acinar necrosis increased simultaneously after the activation of SSAT, depletion of spermidine, and development of apoptosis. In taurodeoxycholate pancreatitis, necrosis developed along with the accumulation of TAP. SSAT was activated simultaneously or after TAP accumulation and less than in the transgenic model, with less depletion of spermidine than in the transgenic model. Supplementation with Me(2)Spm ameliorated the extent of acinar necrosis at 24 h, but contrary to previous findings in the transgenic model, in the taurodeoxycholate model it did not affect trypsin activation. Compared with the transgenic model, no extensive apoptosis was found in taurodeoxycholate pancreatitis. CONCLUSIONS:
