Fig. 3. Intracellular trehalose reduces ubiquitinated proteins during hypoxia. (A) Western signals of ubiquitinated proteins and ß-actin. (B) Relative amount of ubiquitinated proteins per same amount of total proteins after hypoxic treatment for 0, 1, 2 and 3 days in HEK-v and HEK-dtps1 cells. This figure shows that there was almost no difference in the ratio of ubiquitinated proteins/ß-actin between HEK-v and HEK-dtps1 cells at days 0 and 1 of hypoxia exposure. However, as exposure time increased, there was a significant difference on days 2 and 3. ^*P<0.05 compared to HEK-dtps1 cells.
