LGALS4 and Hypoglycemia: Finally, we show that hs-akh expression in larvae with reduced amon function in the AKH cells (yw; hs-akh/uas-amon-RNAi28b; akh-gal4/+) was sufficient to restore glucose and trehalose to control levels (Figure 4, gray bar), indicating that amon functions upstream of AKH to prevent hypoglycemia.
