Figure 2: Transient elevation of proteasome activity following caerulein stimulation.
From: Proteasome activity is required for the initiation of precancerous pancreatic lesions

(a) H&E staining, Alcian blue staining, fluorescence imaging, and immunofluorescence staining for amylase and cytokeratin19 (CK19) of the pancreas of caerulein-treated Gdeg mice (n = 4). Bar, 100 μm. (b) The Gdeg-positive rate in acinar cells was quantified in each group. Values are shown as mean ± SD. The Gdeg-positive rates were 69.3% ± 3.1% in control mice, 32.5% ± 5.2% in mice at day 1, and 60.2% ± 1.0% in mice at day14, respectively.
